Partnership self-employment tax is not optional—general partners must pay it on virtually all partnership income. Most partnerships generate significant self-employment tax bills because federal law requires partners to be self-employed, not employees. Self-employment tax consists of Social Security and Medicare contributions that total 15.3%, and it applies to partnership income that flows through to owners on Schedule K-1. The only major exception is limited partners, who typically avoid self-employment tax on their share of profits—but recent court rulings show that even limited partners may owe it if they actively participate in running the business. Understanding which type of partner you are determines whether you pay this tax, how much you owe, and which forms you must file.
According to the IRS, approximately 15.3% of all partnership income gets hit with self-employment tax when partners report earnings. This creates a combined tax burden that catches many owners off guard because partnership income gets taxed twice: once as regular income tax, and again as self-employment tax.

The Core Problem: Three Types of Partners, Two Different Tax Rules
The partnership self-employment tax issue starts with federal law itself. IRC Section 1402 says partners must include their share of partnership income in their “net earnings from self-employment,” which gets taxed at a flat 15.3% rate. However, Section 1402(a)(13) creates an exception for limited partners, excluding them from self-employment tax—but only on their share of partnership profits, not on guaranteed payments for services.
The problem is that this exception looks simple on the surface but causes massive confusion in real practice because the law doesn’t clearly define what a “limited partner” actually is for tax purposes. For decades, the IRS and taxpayers simply used state law to determine limited partner status. If your state law said you were a limited partner, you got the tax break. But that changed dramatically in 2023 when the Tax Court ruled in Soroban Capital Partners case that state law designation doesn’t matter—what matters is what you actually do in the partnership.
This ruling created urgent confusion for investment funds, family offices, and other partnerships that had relied on limited partner status to avoid self-employment tax on profits while partners actively managed the business. The Tax Court said the IRS could look at the facts and determine that someone labeled a “limited partner” under state law was really functioning like a general partner, making all their income subject to self-employment tax.
The Three Partner Types and How Each Gets Taxed
General Partners: All Income Is Subject to Self-Employment Tax
A general partner is someone who actively participates in management and bears liability for partnership debts. General partners must include entire distributive share of partnership ordinary business income in their net self-employment income, regardless of whether they materially participated in earning that income. This is not optional. General partners also must pay self-employment tax on any guaranteed payments they receive for services to the partnership.
The calculation works like this: Take your share of partnership profits, multiply by 92.35%, then apply the 15.3% self-employment tax rate to that amount. The 92.35% figure exists because employees pay half of their Social Security and Medicare taxes through payroll withholding—so self-employed people get to exclude that equivalent portion to avoid double-taxation of the employer’s share.
Example: Maria and James Partnership
Maria and James form a general partnership to run a consulting firm. The partnership generates $200,000 in net profit for the year. They split profits 50-50. Maria receives $100,000 as her share. Here’s what Maria owes:
| Step | Calculation |
|---|---|
| Start with partnership income | $100,000 |
| Multiply by 92.35% factor | $100,000 × 0.9235 = $92,350 |
| Apply 15.3% self-employment rate | $92,350 × 0.153 = $14,130 |
Maria owes $14,130 in self-employment tax, in addition to regular income tax on the $100,000. James calculates the same way and owes another $14,130.
Limited Partners: Usually No Self-Employment Tax on Profits, But All On Guaranteed Payments
Limited partners get special break under IRC Section 1402(a)(13). They can exclude their distributive share of partnership profits from self-employment income—meaning no 15.3% tax on that profit share. However, this exception does not apply to guaranteed payments. Any amount the partnership pays a limited partner as compensation for services gets treated as self-employment income.
The reasoning behind this exception: Limited partners typically contribute capital but don’t work in the business. They’re passive investors. Congress didn’t want to force them into Social Security contributions on investment returns. But when a limited partner receives payment for actual work performed, that work income still counts as self-employment income because the partner is providing services.
Example: Alex’s Limited Partnership Investment
Alex invests $50,000 in a real estate limited partnership. At the end of the year, his share of the partnership’s profits is $10,000. As a true limited partner, Alex owes $0 in self-employment tax on that $10,000 profit—it’s his return on capital invested.
But suppose the partnership also paid Alex $5,000 as a guaranteed payment for managing the property and handling tenant calls (even though he’s a limited partner). That $5,000 counts as self-employment income because it’s compensation for work performed. So Alex must calculate self-employment tax: $5,000 × 0.9235 × 0.153 = $705.
LLC Members Taxed as Partnerships: It Depends On Whether They’re “Really” Limited
This is where modern partnership taxation gets tangled. Federally, multi-member LLCs are taxed as partnerships. The IRS looks at whether members are manager-managed or member-managed, and whether individual members actually participate in running the business. If you’re an LLC member in a member-managed LLC, you’re treated like a general partner for self-employment tax purposes, meaning all your profits get hit with the 15.3% tax.
But here’s the catch: Even if your LLC operating agreement says you’re a “limited member” or the LLC is “manager-managed,” the IRS and Tax Court may say you’re really functioning as a general partner because you make business decisions. The Soroban ruling and the follow-up Denham Capital case in 2024 hammered this point home. The courts examined what the partners actually did—not just their titles—to determine tax status.
The Limited Partner Exception Has Functional Requirements, Not Just Title
How Courts Now Determine “Limited Partner” Status
The 2023 Soroban Capital Partners decision changed everything. The Tax Court held that “limited partner” for self-employment tax purposes is defined functionally, not by state law or organizational documents. A functional analysis means the court (or IRS) will examine what the partner actually does: How much time did they spend on business? Did they make management decisions? Did they hire or fire people? Did they negotiate contracts?
The test asks whether the partner is functioning as a passive investor or as an active business participant. If a partner’s role is passive, they keep the limited partner exception. If their role is active and essential to the business, they lose the exception and owe self-employment tax on all partnership income.
In Soroban, the Tax Court looked at whether the partners’ skills and judgment were essential to earning the partnership’s income. The court examined the percentage of time partners devoted to the business, whether they had power to hire, fire, or compensate employees, and whether the partnership marketed the partners’ specific expertise to clients. If the answer to any of these questions was “yes” in a way that showed the partner was central to generating income, the Tax Court said the partner was not truly limited—and therefore not entitled to the exception.
The Functional Analysis Test: Five Key Factors
Courts now examine these factors to determine whether someone claiming limited partner status is really limited:
| Factor | What This Means |
|---|---|
| Time Devoted | Does the partner spend most of their business hours on this partnership? High time commitment suggests active participation, not passive investment. |
| Essential Skills | Are the partner’s skills and judgment critical to the partnership’s success? If clients hire the partnership because of this partner’s reputation, they’re active. |
| Management Authority | Does the partner have power to hire, fire, or compensate others? Decision-making power suggests general partner-like control. |
| Role In Income Generation | Does the partner perform services that directly generate revenue? Service providers (lawyers, consultants, managers) are typically active. |
| Ownership vs. Capital Return | Is the partner’s income mostly from work effort or mostly from invested capital? Income from work effort means they’re functioning like a general partner. |
Example: Investment Fund Founders as Limited Partners
Venture capital funds often form as limited partnerships. Five wealthy investors each contribute $1 million and are listed as limited partners. Then three fund managers are also listed as limited partners but actually run the fund full-time: they evaluate deals, negotiate investments, manage the portfolio, and make all decisions.
Before Soroban, those managers could have argued they were limited partners entitled to exclude their share of profits from self-employment tax. After Soroban, the Tax Court would say: These managers spend 40+ hours per week on the fund. Their judgment is essential. They make all major decisions. They function as general partners. Therefore, all their income is subject to self-employment tax. The exception doesn’t apply just because the organizational documents say “limited partner.”
This is exactly what happened in the Denham Capital case decided in 2024. The Tax Court found that five investment managers who were technically limited partners under state law had to pay self-employment tax on all their distributive share because they were actively involved in running the fund.
How Self-Employment Tax Gets Calculated: The 92.35% Method
Self-employment tax is not 15.3% of all partnership income. Instead, it’s 15.3% of 92.35% of your net partnership income. This sounds confusing but it’s actually fair: The 92.35% factor accounts for the fact that regular employees only pay half of Social Security and Medicare taxes because employers pay the other half. Self-employed people pay both halves—which is 15.3%—but only on 92.35% of earnings to avoid taxing the employer portion.
Here’s the formula:
Net Partnership Income × 92.35% × 15.3% = Your Self-Employment Tax
However, the Social Security portion (12.4%) applies only up to a wage base limit. For 2025, that limit is $176,100 wage base. The Medicare portion (2.9%) has no ceiling—it applies to all net earnings. Additionally, once your total net self-employment income exceeds $200,000 (for single filers) or $250,000 (for married filing jointly), an extra 0.9% Medicare surtax kicks in.
Example: Calculating Multi-Tier Self-Employment Tax
Suppose you have $180,000 in net self-employment income from a partnership. Here’s how to calculate:
| Component | Calculation |
|---|---|
| Social Security (12.4%): Income up to $176,100 capped, multiply by 92.35% ($176,100 × 0.9235 = $162,670), then apply rate ($162,670 × 0.124) | $20,171 |
| Medicare (2.9%): All earnings subject, multiply by 92.35% ($180,000 × 0.9235 = $166,230), then apply rate ($166,230 × 0.029) | $4,821 |
| Additional Medicare surtax (0.9%): Applies if income exceeds $200,000 single/$250,000 married (not applicable here) | $0 |
| Total self-employment tax | $24,992 |
This gets reported on Schedule SE attached to your Form 1040 individual tax return.
Guaranteed Payments vs. Profit Distributions: Critical Differences
Understanding the difference between guaranteed payments and profit distributions is essential because they get taxed differently on self-employment income.
Guaranteed Payments: Always Subject to Self-Employment Tax
A guaranteed payment is amount the partnership pays to a partner for services rendered or for use of capital, and the payment is not dependent on partnership profits. In other words, the partnership writes the check to the partner whether the business made money that year or not. Guaranteed payments are like a salary, except partners don’t get W-2 forms—they get reported on Schedule K-1.
Guaranteed payments are always included in the partner’s net self-employment income. This applies to all partners—general partners, limited partners, and LLC members taxed as partnerships. If you receive a guaranteed payment, you owe self-employment tax on it.
Profit Distributions: Tax Treatment Depends on Partner Type
Profit distributions are the partner’s share of what’s left after the partnership pays all expenses and guaranteed payments. The tax treatment depends on partner status:
- General partners: Must include profit distributions in self-employment income
- True limited partners: Can exclude profit distributions from self-employment income
- Limited partners acting as active participants: Must include profit distributions in self-employment income (per Soroban)
| Payment Type | Guaranteed Payments | Profit Distributions |
|---|---|---|
| General Partner | ✓ Must pay self-employment tax | ✓ Must pay self-employment tax |
| Limited Partner (Passive) | ✓ Must pay self-employment tax | ✗ NO self-employment tax |
| Limited Partner (Active) | ✓ Must pay self-employment tax | ✓ Must pay self-employment tax |
| Multi-Member LLC Member | ✓ Must pay self-employment tax | ✓ Usually must pay self-employment tax |
Example: Two Partners, Two Different Tax Outcomes
Real estate partnership owns apartment buildings. Partnership has $150,000 in profit after expenses.
- Partner A is a general partner who works full-time at the partnership. The partnership pays Partner A a guaranteed payment of $50,000. Partner A’s share of remaining profit is $50,000 (half of remaining $100,000).
- Guaranteed payment: $50,000 × 0.9235 × 0.153 = $7,050 in SE tax
- Profit share: $50,000 × 0.9235 × 0.153 = $7,050 in SE tax
- Total SE tax: $14,100
- Partner B is a limited partner (true passive investor) who contributed capital but does no work. Partner B receives no guaranteed payment. Partner B’s share of profit is $50,000.
- Guaranteed payment: $0
- Profit share: $0 in SE tax (limited partner exception applies)
- Total SE tax: $0
Partner A owes $14,100 in self-employment tax. Partner B owes $0. Same partnership, same profit, but completely different tax outcomes because of partner status.
The Three Most Common Partnership Self-Employment Tax Scenarios
Scenario 1: Traditional General Partnership With Active Partners
A general partnership has multiple partners who all work in the business. Each partner must pay self-employment tax on their entire distributive share of ordinary business income plus any guaranteed payments they receive. There’s no exception—this is the default rule.
| Situation | Tax Consequence |
|---|---|
| Partner works full-time in business | Must include all profit share in SE income |
| Partner receives guaranteed compensation | Must pay SE tax on guaranteed payments |
| Partner receives distributions of profits | Must pay SE tax on profit distributions |
| Partner takes a distribution (return of capital) | No SE tax on capital return |
Real-World Example: Law Firm Partnership
A law firm has four partners. In year one, the firm earns $400,000 in gross revenue. After paying staff, rent, and expenses, the partnership has $200,000 in net profit. The partners allocate profits equally: $50,000 each.
- Partner 1: Spends 40 hours per week on client work and firm management. Receives $50,000 profit share.
- Partner 2: Spends 35 hours per week on client work. Receives $50,000 profit share.
- Partner 3: Works 25 hours per week, mainly on business development. Receives $50,000 profit share.
- Partner 4: New equity partner who works 30 hours per week. Receives $50,000 profit share.
All four partners must report their $50,000 share on Schedule K-1 from Form 1065. Each calculates: $50,000 × 0.9235 × 0.153 = $7,050 in self-employment tax. The partnership didn’t pay anyone a separate “salary” or guaranteed payment—just a profit distribution—but all four still owe self-employment tax because they’re all general partners.
Scenario 2: Limited Partnership With Some Passive Investors, Some Active Managers
An investment partnership has both true passive limited partners (who invested money and don’t touch the business) and one or more general partners (who actively manage investments). The passive limited partners typically owe no self-employment tax on profits, only on guaranteed payments if any. The general partners owe SE tax on everything.
| Situation | Tax Consequence |
|---|---|
| Limited partner who invested capital only | No SE tax on profit share |
| Limited partner who does management work | Depends on Soroban functional test; likely subject to SE tax |
| General partner who manages investments | Must pay SE tax on all profits |
| Either type receives guaranteed payment | Must pay SE tax on guaranteed payment |
Real-World Example: Real Estate Syndication
An apartment building investment syndication has a structure designed to protect passive investors. There’s one general partner (the syndicator) and 20 limited partners (passive investors).
- General Partner (Syndicator): Found the deal, raises capital, manages property, handles tenant issues. Receives guaranteed payment of $30,000 annually plus 10% of cash flow distributions.
- Must pay SE tax: $30,000 guaranteed payment + 10% of profits
- Limited Partners (Investors): Each invested $50,000-$100,000. No management role. Receive only their pro-rata share of cash distributions.
- No SE tax on distributions (traditional limited partner exception)
- Would owe SE tax only if they received separate guaranteed payment for services
- What if a Limited Partner starts actively managing the property after three years?
- Under Soroban, the IRS might argue this partner is now functioning as an active manager, not a passive investor
- The partner would lose the limited partner exception and owe SE tax on all profits
- This is exactly what concerned family offices and investment firms after the ruling
Scenario 3: Multi-Member LLC Taxed as Partnership With Mixed Manager/Non-Manager Members
An LLC with several members—some designated as “managers” and others as non-managers—gets classified as a partnership for federal tax purposes. The IRS now looks at whether each member actually participates in management decisions.
| Situation | Tax Consequence |
|---|---|
| Manager-member who makes daily decisions | Treated like general partner; must pay SE tax on all profits |
| Non-manager member who never participates | Depends on practical reality per Soroban; likely no SE tax if truly passive |
| Member who does some tasks but not management | Depends on whether role is essential to earning income |
| Any member receiving guaranteed payment for services | Must pay SE tax on guaranteed payment |
Real-World Example: Private Equity Fund as Member-Managed LLC
A private equity fund is structured as a member-managed LLC with three members:
- Member 1: The founder. Spends 50 hours per week evaluating deals, managing portfolio companies, making investment decisions. Designated as a manager. Receives 10% of profits.
- Per Soroban: Must pay SE tax on all 10% of profits because role is active and essential
- Member 2: A junior analyst. Spends 30 hours per week on deal analysis and portfolio monitoring. Not designated as a manager. Receives 2% of profits.
- Per Soroban: Likely must pay SE tax because she spends significant time and her analytical skills are essential to investment decisions
- Member 3: A silent investor who contributed capital. Does no work. Not a manager. Receives 3% of profits.
- Could argue for limited partner exception if truly passive
- But if the LLC is member-managed (not manager-managed), the IRS might argue all members are general partners regardless
- Better documentation needed to support passive status
How To File: Forms, Schedules, and Step-By-Step Instructions
Step 1: The Partnership Files Form 1065 and Issues Schedule K-1 to Each Partner
The partnership itself files Form 1065, U.S. Return of Partnership Income, with the IRS by April 15 (or applicable extension date). This form reports all partnership income, deductions, losses, and credits. The partnership does not pay income tax—it’s a pass-through entity. Instead, Form 1065 allocates each partner’s share to Schedule K-1, which the partnership issues to each partner individually.
Schedule K-1 reports partnership income allocation details:
- Ordinary business income (line 1)
- Net rental real estate income
- Other rental income
- Guaranteed payments for services (separate box)
- Self-employment income (box 14, code A)
Nuance: Not all partnership income appears on line 14 (self-employment income). Only income from active business operations gets reported there. Passive rental income, capital gains, and interest income typically do not appear on line 14. This distinction matters because only line 14 income triggers self-employment tax.
Step 2: Each Partner Reports Schedule K-1 on Their Individual Return
Each partner receives their copy of Schedule K-1 showing their allocated share. The partner then uses this information to complete their own individual Form 1040 tax return.
For General Partners or LLC Members:
- Take the amount from Schedule K-1, box 14 (self-employment income)
- Report it on Schedule SE (Self-Employment Tax Worksheet)
- Calculate self-employment tax using the 92.35% factor
- Enter self-employment tax on Form 1040
For Limited Partners (if claiming the exception):
- Take only guaranteed payments from Schedule K-1 and report on Schedule SE
- Do NOT report profit distributions on Schedule SE (the limited partner exception excludes them)
- Calculate SE tax only on guaranteed payments
Step 3: Completing Schedule SE—Line By Line Breakdown
Schedule SE is the form that calculates self-employment tax. Most partners don’t do this manually—tax software handles it—but understanding each line matters:
| Line Item | What Goes Here | Why This Matters |
|---|---|---|
| Line 1a: Schedule C income | Net profit/loss from Schedule C (sole proprietors); skip if using 1b-1d | Skip if you’re a partner |
| Line 1b: Schedule F income | Net farm profit/loss from Schedule F | Skip if you’re a partner |
| Line 2: K-1 income | Net profit/loss from Schedule K-1 (partners and LLC members) | Your profit share from Form 1065 K-1 |
| Line 3: Guaranteed payments | Guaranteed payments to you from partnerships | Required if you received guaranteed payments |
| Net earnings figure | (Line 2 + Line 3) minus certain deductions | This is your starting point for SE tax |
| Multiple businesses | If you have Schedule C AND Schedule K-1 income, combine them | Losses from one business reduce SE tax on another |
Let me convert this to 2-column format:
| Line Item | Explanation |
|---|---|
| Lines 1a & 1b (Schedule C/F) | Skip if you’re a partner; these are for sole proprietors |
| Line 2 (K-1 income) | Your profit share from Form 1065 Schedule K-1 |
| Line 3 (Guaranteed payments) | Required entry if you received guaranteed payments for services |
| Net earnings calculation | (Line 2 + Line 3) minus certain deductions = starting point for SE tax |
| Multiple businesses | Combine Schedule C AND Schedule K-1 income; losses reduce SE tax from profits |
Example: Completing Schedule SE as a Partner
John is a general partner in a consulting partnership. On his Form 1065 Schedule K-1, he sees:
- Box 1 (Ordinary business income): $120,000
- Box 14, Code A (Self-employment income): $120,000
- Guaranteed payments: $0
John moves to Schedule SE:
| Step | Amount |
|---|---|
| Line 2: Enter K-1 self-employment income | $120,000 |
| Line 3: Enter guaranteed payments | $0 |
| Calculate net earnings | $120,000 |
| Multiply by 92.35% factor | $110,820 |
| Apply 15.3% self-employment tax rate | $16,954 in self-employment tax |
John enters $16,954 on Form 1040 as his self-employment tax.
Important Line-By-Line Nuance: If you have partnership loss and profit from another business, you can combine them on Schedule SE. The loss reduces your self-employment tax on the profitable business. However, basis limitations, at-risk limitations, and passive activity loss limitations might block you from using the loss. This is one of the most common mistakes.
Step 4: Timing and Quarterly Estimated Tax Payments
Because partnerships don’t withhold tax from distributions, most partners must make estimated tax payments quarterly (April 15, June 15, September 15, and January 15 of the following year). If you don’t pay estimated taxes and owe more than $1,000 when you file your return, the IRS imposes penalties and interest.
Each quarterly payment should cover both regular income tax and self-employment tax on partnership income. Use Form 1040-ES (Estimated Tax Worksheet) to calculate what you owe, or consult a tax professional to avoid underpayment penalties.
Pros and Cons of Partnership Self-Employment Tax Treatment
| Advantage | Disadvantage |
|---|---|
| Partners get self-employment credit toward Social Security, which funds future retirement benefits | All partnership income is subject to a flat 15.3% tax with limited exceptions |
| General partners have no income cap on Medicare tax (only Social Security has a cap at $176,100) | Limited partners who actively participate may lose their tax exception under recent court rulings |
| Half of self-employment tax is deductible as an adjustment to gross income, reducing AGI | Self-employment tax applies to all profits, not just distributions actually taken by the partner |
| Limited partners can exclude profit distributions using Section 1402(a)(13) exception | Guaranteed payments for services are taxed at SE rate even for limited partners |
| Flexibility in allocating guaranteed payments vs. profit distributions for tax planning | Multi-member LLC members may be treated as general partners even if operating agreement says otherwise |
| Loss from one business can offset SE tax on another if combined on same Schedule SE | Married couples in spouse-owned partnerships may have to double the maximum Social Security tax ($176,100 × 2) |
Common Mistakes That Trigger IRS Audits and Penalties
Mistake 1: Assuming Limited Partner Status Based Only on Your State Law Title
The Error: A partner reads their operating agreement, sees “Limited Partner” in the title, and assumes they don’t owe self-employment tax on profits.
The Consequence: The IRS applies the Soroban functional analysis test, examines what the partner actually does, and determines the partner is functioning as an active business participant. The IRS adjusts the partner’s return, adds back all profit distributions to self-employment income, and issues a bill for back taxes, plus accuracy-related penalties of 20% on the underpayment.
How To Avoid: Document your actual role. If you claim limited partner status, create a written record showing: (1) you did not make management decisions, (2) you did not spend material time on the business, (3) your income comes from capital invested, not work effort, and (4) your specific expertise was not marketed to clients. Keep time logs if you do any work for the partnership—evidence of 500+ hours per year will trigger self-employment tax.
Mistake 2: Treating a Partner as an Employee on Payroll (Paying W-2 Wages Instead of Reporting on K-1)
The Error: A partnership gives a partner a Form W-2 showing wages instead of reporting all partnership income on Schedule K-1.
The Consequence: The IRS sees the W-2 and may argue the partner is not truly a partner but an employee—or that the partnership failed to report some partnership income. Either way, the IRS may demand back self-employment tax on all partnership income that should have been reported on K-1, plus penalties. Under Revenue Ruling 69-184, partners cannot be employees of their own partnership.
How To Avoid: Never issue a W-2 to a partner. Pay partners through guaranteed payments reported on Schedule K-1, or distributions of profits. If a partner worked as both a partner and a separate employee of an entity owned by the partnership, consult a tax professional immediately—this creates complex issues.
Mistake 3: Failing to Report Guaranteed Payments as Self-Employment Income
The Error: A limited partner receives a guaranteed payment ($40,000) for managing the partnership’s operations but fails to report it on Schedule SE, thinking “I’m a limited partner so I don’t pay SE tax.”
The Consequence: The partnership reports the guaranteed payment on the K-1, but the partner never reports it on Schedule SE. The IRS matches the K-1 to the partner’s return, sees the mismatch, and assesses back self-employment tax (15.3%) on the missed guaranteed payment plus penalties and interest.
How To Avoid: Understand that the limited partner exception applies only to profit distributions, not to guaranteed payments. All guaranteed payments (whether paid to limited or general partners) must be reported on Schedule SE. Set a calendar reminder to enter guaranteed payments on Schedule SE when you complete your return.
Mistake 4: Misallocating Income or Deductions Based on Oral Agreements Instead of Written Partnership Agreement
The Error: Partners verbally agree to split profits 60-40, but the written partnership agreement says 50-50. Partners file their returns based on the oral agreement, not the written one.
The Consequence: The IRS requires partnerships allocate income according to the written partnership agreement unless a special allocation is properly documented and has economic effect under IRC Section 704(b). Partners who file based on an oral agreement will face an adjustment and likely self-employment tax recalculation.
How To Avoid: Ensure your partnership agreement is in writing and clearly specifies profit allocation percentages. Update the agreement if allocations change. Document any special allocations (allocating specific income items to specific partners) in writing with clear business purpose. Have a tax professional review allocations before partners file their returns.
Mistake 5: Combining Losses From Multiple Businesses Incorrectly on Schedule SE
The Error: A partner has $100,000 in partnership income from one partnership and a $50,000 loss from a sole proprietorship. The partner subtracts the loss to get $50,000 of net earnings, then calculates SE tax as if the net earnings were $50,000.
The Consequence: Self-employment tax is calculated on “net earnings from self-employment” as defined by IRC Section 1402. Basis limitations under Section 704(d) and at-risk limitations under Section 465 may block the partner from using the loss to offset the profitable partnership income for SE tax purposes. The IRS disallows the loss offset and recalculates SE tax on the full $100,000. The partner gets hit with a bill for additional SE tax plus penalties.
How To Avoid: Use Schedule SE correctly. You can combine losses from multiple businesses if you have sufficient basis in each business. But consult a CPA before assuming a loss from one business offsets income from another. Basis, at-risk, and passive activity loss limits are complex. A mistakes here costs thousands.
Mistake 6: Failing To File Schedule SE At All (Thinking the Partnership Handles It)
The Error: A partner thinks the partnership’s Form 1065 reporting means the partner doesn’t need to file Schedule SE. The partner skips Schedule SE.
The Consequence: Self-employment tax doesn’t get calculated or paid. Years later, the IRS sends a bill for back SE taxes plus interest and accuracy penalties. The statute of limitations is typically three years, but can extend to six years if underreporting is substantial (20% or more of income).
How To Avoid: Remember: The partnership files Form 1065 for the business. Each partner files Schedule SE on their own Form 1040. These are two separate filings. If your K-1 shows self-employment income, you must file Schedule SE. Use tax software or hire a preparer who understands partnership taxation.
Mistake 7: Not Recognizing That Losses From One Business Cannot Reduce SE Tax Below Zero
The Error: A partner has $60,000 in SE income from a profitable partnership and a $75,000 loss from another business. The partner calculates: $60,000 – $75,000 = -$15,000 net earnings, assumes SE tax is $0.
The Consequence: This is partially correct—you can’t pay negative SE tax—but the partner may have missed the passive activity loss limitation or basis issue that blocked use of the loss in the first place. Or the partner used an inflated loss figure. The IRS denies the loss and recalculates SE tax on the full $60,000, resulting in a surprise bill.
How To Avoid: When combining business income and losses on Schedule SE, first verify that losses are allowable. Check that each business has sufficient basis for losses. Review whether passive activity loss limits block the loss. When in doubt, get professional help before filing.
The Limited Partner Exception and When It Actually Applies: Real Limits
The Written Partnership Agreement Must Clearly Designate Status
To claim limited partner status for tax purposes, your partnership agreement should clearly state that you are a limited partner under state law. But as of Soroban, this is necessary but not sufficient. The IRS will still examine what you actually do.
If you’re asking for limited partner treatment, prepare for audit by documenting:
- Time Records: Show that you spent fewer than 500 hours per year on partnership business. Keep monthly time logs.
- Decision-Making Records: Show that you made no hiring, firing, or compensation decisions. Compile records of partnership meetings showing you didn’t participate in management.
- Capital Contribution: Show that your income primarily reflects return on capital invested, not compensation for services. Calculate the relationship between your capital contribution and your income allocation.
- Marketing and Reputation: Show that the partnership doesn’t use your name or expertise in marketing. Clients don’t hire the partnership because of you specifically.
State Law Designation Alone Is No Longer Sufficient
Before Soroban, being a limited partner under state law nearly guaranteed the limited partner tax exception. After Soroban (2023) and Denham (2024), state law designation is just the starting point. The Tax Court will look at functional reality.
The Supreme Court hasn’t weighed in yet, but lower courts have consistently held that a partner’s actual role trumps the title in the operating agreement.
| Evidence Supporting Limited Partner | Evidence Suggesting Active General Partner |
|---|---|
| Time dedicated to partnership: <100 hours per year | Time dedicated to partnership: >500 hours per year |
| Capital invested: Income is proportional to capital | Expertise marketed: Partnership uses your name and reputation |
| No management decisions: You attend no meetings or observe only | Full management authority: You hire, fire, compensate employees |
| Passive investment: You have no say in hiring decisions | Active role: You negotiate with clients or vendors |
| Income flows from capital return, not services | Income flows from services you personally perform |
Spouse-Owned Partnerships and Double Self-Employment Tax
When married couples own and operate a partnership together, a special problem emerges: double self-employment tax on the same profits. This can cost couples thousands of dollars in unnecessary taxes each year.
How Spouse Partnerships Create Double SE Tax
If you and your spouse jointly own an unincorporated business (partnership or multi-member LLC taxed as partnership), the IRS typically treats it as a 50-50 partnership between two partners. Each spouse calculates their own self-employment tax on their 50% share using a separate Schedule SE.
For 2025, the Social Security portion of SE tax (12.4%) applies to earnings up to $176,100. In a spouse-owned partnership with $300,000 of combined profit, each spouse reports $150,000 as their share. Each spouse then multiplies by 92.35%, then by 15.3%.
- Spouse 1 SE tax: $150,000 × 0.9235 × 0.153 = $21,170
- Spouse 2 SE tax: $150,000 × 0.9235 × 0.153 = $21,170
- Combined: $42,340 in SE tax on $300,000 of profit
If this were a sole proprietorship run by one person, that person would pay: $300,000 × 0.9235 × 0.153 = $42,340. The combined tax is the same, but it gets split between two people. The problem: Because of the $176,100 Social Security wage base cap, each spouse hits the maximum Social Security tax separately.
Compare this to a single-owner sole proprietorship:
One person earning $300,000 from self-employment pays: ($176,100 × 0.9235 × 0.124) + ($300,000 × 0.9235 × 0.029) = $20,081 + $8,074 = $28,155. The higher earner is not hit with double Social Security tax because the wage base applies to one person’s total earnings, not split between two people.
Spouse-owned partnerships can often be avoided or restructured to reduce this double tax hit.
Options to Reduce Spouse Partnership SE Tax
Option 1: Operate as a Sole Proprietorship (One Spouse Only)
If one spouse is the sole operating owner and the other spouse is not actively involved in management or day-to-day operations, the business might qualify as a sole proprietorship run by one person only. The other spouse can be an employee (paid W-2 wages with FICA taxes withheld) or an independent contractor.
Advantage: Only one Schedule SE filed; no double Social Security tax on the same profits.
Disadvantage: The non-partner spouse doesn’t build Social Security credits if not compensated as an employee.
Option 2: Elect to Be Treated as an S-Corporation
The LLC (or partnership) can elect to be taxed as an S-Corporation by filing Form 2553. In an S-Corp, the spouses become shareholders, not partners. They pay themselves a reasonable W-2 salary (subject to payroll taxes: 15.3%), and remaining profits are distributed as dividends that avoid self-employment tax.
Example: A spouse-owned LLC generates $300,000 profit. The S-Corp elects to pay the spouses $150,000 each in salary (reasonable compensation for the work performed). Payroll taxes: $150,000 × 0.9235 × 0.153 × 2 = $42,340—exactly what they’d owe in a partnership. But the savings come from any income above the salary.
If they paid $200,000 total in salaries and received $100,000 in distribution dividends, the payroll tax is on salaries only ($200,000), not the full $300,000. This saves on self-employment tax.
Advantage: Can reduce overall FICA tax burden if structured correctly.
Disadvantage: Adds accounting complexity and requires payroll processing.
Option 3: Qualified Joint Venture Election (Non-Community Property States)
If you’re in a non-community property state and both spouses file jointly and materially participate, you can make a “Qualified Joint Venture” election. This avoids partnership taxation while recognizing both spouses as business participants. Each spouse files a separate Schedule C for their share of income, avoiding the need for Form 1065 and Schedule K-1.
Advantage: Simplifies compliance; each spouse gets separate Social Security credit; often no reduction in total SE tax but avoids partnership reporting complexity.
Disadvantage: Only available in non-community property states; both spouses must materially participate; still results in similar overall SE tax amount.
Option 4: Own Partnership Stake Through an S-Corporation
If the spouses want to remain as partners but reduce their SE tax burden, one spouse can own their partnership interest through an S-Corporation. The S-Corp pays the spouse a salary (subject to payroll taxes) and receives distributions as dividends (not subject to SE tax). This creates a “buffer” between the partner and the self-employment tax rules.
Example: Spouse A owns 50% of partnership directly; Spouse B owns 50% through an S-Corp. The partnership distributes $150,000 to Spouse A (no SE buffer). Spouse A pays: $150,000 × 0.9235 × 0.153 = $21,170 in SE tax. The partnership distributes $150,000 to the S-Corp owned by Spouse B. The S-Corp pays Spouse B a salary of $100,000 (payroll taxes: $15,300) and receives $50,000 in non-taxable distributions.
Spouse B’s total tax: $15,300 in payroll tax + $0 SE tax on distributions = $15,300 (compared to $21,170).
Advantage: Reduces one spouse’s SE tax burden by filtering income through S-Corp.
Disadvantage: Adds another business entity; requires careful tax planning; IRS has challenged similar structures (must ensure reasonable salary).
Do’s and Don’ts for Partnership Self-Employment Tax Compliance
Do’s
- Do file Schedule SE for any self-employment income reported on your Schedule K-1 — this is mandatory if you have net self-employment income of $400 or more
- Do keep written records of your actual role in the partnership — time logs, decision-making documentation, and capital contribution records support your limited partner status claim
- Do understand the difference between guaranteed payments (always taxable) and profit distributions (taxable for general partners, often not for true limited partners)
- Do make quarterly estimated tax payments if you expect to owe $1,000 or more in federal income tax plus self-employment tax
- Do review your Schedule K-1 from the partnership before filing your return to ensure box 14 (self-employment income) is accurate
- Do combine income and losses from multiple self-employment businesses on a single Schedule SE if you have more than one business (subject to basis and loss limitation rules)
- Do deduct 50% of your self-employment tax as an adjustment to gross income on Form 1040 or Schedule 1
Don’ts
- Don’t assume you don’t owe self-employment tax because you’re called a “limited partner” — the IRS now applies a functional test
- Don’t treat a partner as a W-2 employee — this violates Rev. Rul. 69-184 and exposes the partnership to payroll tax compliance failure
- Don’t fail to report guaranteed payments on Schedule SE — limited partners still owe SE tax on compensation for services
- Don’t skip Schedule SE if you have any self-employment income — the IRS will catch the omission and impose back taxes plus penalties
- Don’t use losses from one business to reduce self-employment tax below zero — losses cannot create negative SE tax
- Don’t ignore basis limitations, at-risk limitations, or passive activity loss limitations when combining business income and losses
- Don’t assume a verbal profit-sharing agreement will override your written partnership agreement — allocations must be documented in writing
FAQ: Self-Employment Tax for Partnerships and LLCs
Q1: If I’m a limited partner and don’t work in the partnership, do I owe any self-employment tax?
No. If you’re a true limited partner under IRC 1402(a)(13) and receive only your share of partnership profits (no guaranteed payments for services), you owe no self-employment tax on those profits. However, any guaranteed payments the partnership pays you for services must be reported on Schedule SE. The recent Soroban and Denham rulings make it risky to claim limited partner status if you actually participate in management.
Q2: I’m a general partner with a $50,000 share of partnership profits. How much self-employment tax do I owe?
Yes, $7,050. Calculate: $50,000 × 0.9235 × 0.153 = $7,050. This applies to all general partners regardless of how much actual work they perform for the partnership. As a general partner, all profit shares are subject to self-employment tax.
Q3: My LLC is taxed as a partnership. Am I treated as a general partner or limited partner for self-employment tax?
Depends on facts. The IRS no longer uses your LLC’s operating agreement title. It examines your actual role. If you manage the LLC and make business decisions, you’re treated as a general partner. If you truly don’t participate in management and your role is purely passive investment, you might qualify as a limited partner—but the burden is on you to prove it with documentation.
Q4: Can I reduce my partnership self-employment tax by electing S-Corp status?
Yes, potentially. If your multi-member LLC elects to be taxed as an S-Corporation, you become a shareholder and pay yourself a reasonable W-2 salary (subject to payroll taxes), with remaining income distributed as dividends (not subject to self-employment tax). This saves SE tax only if you can reduce salary below 100% of profits. The IRS scrutinizes these structures to ensure salary is reasonable.
Q5: My spouse and I own a partnership 50-50. Can we avoid double self-employment tax?
Possibly. Several options exist: (1) Operate as a sole proprietorship with one spouse as owner only; (2) Elect S-Corp status; (3) Use a Qualified Joint Venture election (non-community property states); or (4) Own your partnership interest through an S-Corp buffer. Each option has tradeoffs. Consult a CPA to choose the best structure for your situation.
Q6: I received a guaranteed payment from my limited partnership. Do I owe self-employment tax on it?
Yes, $705 on $5,000. All guaranteed payments (compensation for services) are subject to self-employment tax regardless of partner status. Calculate: $5,000 × 0.9235 × 0.153 = $705. Limited partners don’t escape SE tax on guaranteed payments—only on profit distributions.
Q7: If my partnership has a loss year, do I still owe self-employment tax?
No. If the partnership has a net loss, you don’t owe self-employment tax on that loss. However, if you have other self-employment income from a separate business with a profit, the partnership loss may offset it (subject to basis and loss limitation rules).
Q8: What happens if I don’t file Schedule SE when I should have?
IRS audit, back taxes, and penalties. The IRS matches your Schedule K-1 to your filed return. If you don’t report self-employment tax and didn’t file Schedule SE, the IRS will send a notice of deficiency. You’ll owe back SE taxes, plus interest (currently ~8% annually) and a 20% accuracy-related penalty. This can add 40%+ to your bill.
Q9: Can I be both a partner and an employee of my partnership?
No. Rev. Rul. 69-184 prohibits this. A person cannot be treated as both an employee (W-2) and a partner (K-1) of the same partnership. You’re either one or the other. If you’re a partner who also performs additional services beyond your partnership role, negotiate it through guaranteed payments or profit allocation, not W-2 wages.
Q10: If I have $300,000 in partnership income but it’s all guaranteed payments and no profit distributions, how much self-employment tax do I owe?
Yes, $45,900. Calculate: $300,000 × 0.9235 × 0.153 = $45,900. Guaranteed payments are fully subject to self-employment tax, just like self-employment income. The 92.35% factor and 15.3% rate apply. Being a limited partner offers no exception to guaranteed payments.
Q11: The partnership didn’t file its Form 1065 on time. Am I still liable for self-employment tax?
Yes. Your self-employment tax obligation is independent of whether the partnership filed Form 1065 on time. If you have actual self-employment income from the partnership, you must report it on Schedule SE by the due date of your return, regardless of the partnership’s filing status. Late partnership returns don’t eliminate your SE tax duty.
Q12: Do I have to make quarterly estimated tax payments if I’m a partner?
Yes, if you expect to owe $1,000+. Partnerships don’t withhold taxes from distributions. If your self-employment tax plus regular income tax will exceed $1,000 when you file, you should make quarterly estimated payments (April 15, June 15, September 15, January 15). Failure to pay estimated taxes results in underpayment penalties.
Q13: I lost my Schedule K-1. Can I still file my tax return?
Not ideally. You need your Schedule K-1 to know your exact profit share and guaranteed payments. Contact the partnership and request a copy. If the partnership can’t provide it, estimate conservatively based on your capital contribution and business performance. But filing without the K-1 is risky and may trigger an audit if your estimate doesn’t match the partnership’s Form 1065.
Q14: Are LLC members always subject to self-employment tax on profits?
Not always. Single-member LLCs are treated as sole proprietorships—owner pays SE tax on all profits. Multi-member LLCs taxed as partnerships: members are treated like general partners by default (SE tax on all profits) unless they meet limited partner criteria. Passive members might avoid SE tax, but the burden is on you to prove it with documentation of your passive role.
Q15: If the partnership is in a state without state income tax, do I still owe federal self-employment tax?
Yes. Self-employment tax is a federal tax, not a state tax. It funds Social Security and Medicare regardless of state income tax rules. Even if your state has no income tax, you owe federal self-employment tax on partnership income if it meets the threshold ($400+).
