No — a Charitable Remainder Unitrust (CRUT) itself does not pay federal income tax. Under IRC Section 664, a CRUT is a tax-exempt entity, which means the trust keeps every dollar of investment growth inside it without owing the IRS a cent. The catch is that beneficiaries owe income tax on the distributions they receive, and the IRS uses a strict four-tier system to decide how those payouts get taxed. According to the IRS’s own data on split-interest trusts, tens of thousands of CRTs file Form 5227 each year, managing billions of dollars in charitable assets nationwide.
There is one painful exception: if a CRUT earns unrelated business taxable income (UBTI), it faces a 100% excise tax on that UBTI — the IRS takes every penny. This makes knowing what goes into a CRUT just as important as knowing what comes out.

What Is a Charitable Remainder Unitrust?
A CRUT is an irrevocable trust that splits its benefits between you (the income beneficiary) and a charity (the remainder beneficiary). You transfer assets into the trust, receive annual payouts for life or a set term of up to 20 years, and when the trust ends, whatever is left goes to one or more qualified charities.
The IRS requires that the annual payout be a fixed percentage — between 5% and 50% of the trust’s fair market value — recalculated each year. This annual recalculation is what makes a CRUT different from a CRAT (which pays a fixed dollar amount). The trust must also pass the “10% remainder test,” meaning the IRS must project that at least 10% of the initial contribution will end up going to charity.
When you create a CRUT, you receive an immediate income tax deduction equal to the present value of the charitable remainder interest. That deduction is calculated using the IRS Section 7520 discount rate, your age, and the payout percentage. A higher 7520 rate produces a larger deduction because the IRS assumes the trust will grow faster, leaving more for charity.
Three Types of CRUTs
Not all CRUTs work the same way. The IRS recognizes three variations, and each serves a different financial goal.
Standard CRUT (SCRUT)
A Standard CRUT pays you a fixed percentage of the trust’s assets every year, no matter what. If the trust is worth $1,000,000 and your payout rate is 5%, you receive $50,000 that year. If the trust grows to $1,200,000 the next year, you receive $60,000. If the trust drops to $900,000, you receive $45,000. The payout always tracks the trust’s current value.
Net Income with Makeup CRUT (NIMCRUT)
A NIMCRUT pays you the lesser of the fixed percentage or the trust’s actual net income. If the trust earns less than 5% in a given year, you get only what the trust earned. But the shortfall gets tracked in a “makeup account.” In future years when the trust earns more than 5%, it pays you the extra to make up for past shortfalls.
This structure is ideal for trusts funded with assets that do not produce income right away — like raw land or a startup investment. The makeup provision allows deferred income to catch up later when the trust has cash.
Flip CRUT
A Flip CRUT starts as a NIMCRUT and then flips into a Standard CRUT when a specific triggering event occurs. The most common trigger is the sale of an illiquid asset — such as real estate or closely held stock — that was used to fund the trust. Before the flip, the trust pays only net income. After the flip, it pays the full unitrust percentage.
A donor who contributes $1,000,000 in appreciated real estate to a Flip CRUT with a 5% rate might receive very little income while the property sits unsold. Once the property sells, the trust flips, and the donor begins receiving 5% of the trust’s total value each year. This gives the trustee time to liquidate the asset without being forced to make distributions from an empty cash account.
How CRUTs Are Taxed at the Trust Level
A CRUT is treated as a tax-exempt entity under IRC Section 664(c). This means the trust pays zero federal income tax on interest, dividends, capital gains, and other investment income it earns. When the trust sells appreciated stock or real estate, it owes no capital gains tax on the sale. The full proceeds stay inside the trust and continue to grow.
This is one of the most powerful features of a CRUT. If you sold $500,000 of appreciated stock on your own, you might owe $100,000 or more in federal capital gains tax. But if a CRUT sells that same stock, it keeps the full $500,000 invested. The tax-free growth inside the trust means more money generating income for you and more money left over for charity.
However, the trust does owe taxes in one specific situation. If the CRUT earns unrelated business taxable income — known as UBTI — it faces a 100% excise tax on that income. This is covered in detail later in this article.
The Four-Tier Taxation System
While the trust pays no income tax, the beneficiary does — on every distribution received. The IRS uses a strict ordering system called the four-tier system under IRC Section 664(b) to classify each distribution. The tiers determine how your payout gets taxed. Think of it like a stack — the IRS forces you to empty the highest-taxed bucket first before moving to the next.
Tier 1: Ordinary Income
Distributions are first treated as ordinary income — including interest, rents, and nonqualified dividends — to the extent the trust has current or accumulated ordinary income. This tier is taxed at your regular federal income tax rate, which can be as high as 37%.
Qualified dividends sit in a subcategory of Tier 1 but are taxed at the lower long-term capital gains rate of 15% or 20%. The IRS requires the trustee to separate ordinary income into its subcategories on the trust’s tax return.
Tier 2: Capital Gains
After all ordinary income is distributed, the next dollars come from capital gains. Tier 2 has its own subcategories ranked by tax rate: short-term capital gains first (taxed at ordinary rates), then gains from collectibles (taxed at 28%), then unrecaptured Section 1250 gains from real estate (taxed at 25%), and last, long-term capital gains (taxed at 15% or 20%).
Tier 3: Other Income
This tier covers tax-exempt income, such as interest from municipal bonds. If the trust holds tax-exempt securities, distributions from this tier are not taxed to the beneficiary.
Tier 4: Return of Principal
Any remaining distribution — after tiers 1 through 3 are exhausted — comes from the trust’s corpus (principal). This is a tax-free return of your original contribution and carries no income tax.
Why the Tier System Matters
The tiers mean the IRS always taxes your highest-rate income first. You cannot cherry-pick favorable capital gains while the trust has accumulated ordinary income sitting in Tier 1. This is why investment strategy inside a CRUT matters — a trust loaded with interest-bearing bonds will push more ordinary income through Tier 1, resulting in higher taxes for the beneficiary.
Example: Arvind creates a CRUT and receives a $70,000 distribution. The trust has $25,000 of taxable interest, $10,000 of qualified dividends, $5,000 of short-term capital gains, and $30,000 of long-term capital gains. Under the four-tier system, the $70,000 payout is treated as:
| Income Type | Amount |
|---|---|
| Taxable interest (Tier 1 — ordinary rate) | $25,000 |
| Qualified dividends (Tier 1 — preferential rate) | $10,000 |
| Short-term capital gains (Tier 2 — ordinary rate) | $5,000 |
| Long-term capital gains (Tier 2 — preferential rate) | $30,000 |
Arvind owes tax on each piece at its respective rate. He cannot choose to receive the long-term gains first.
The Charitable Income Tax Deduction
When you fund a CRUT, you receive an immediate income tax deduction equal to the present value of the projected remainder interest that will pass to charity. The IRS calculates this value using three inputs: the Section 7520 discount rate at the time you create the trust, your age (or the ages of the income beneficiaries), and the payout percentage.
The deduction limit depends on what you donate and who receives the remainder. Cash gifts to a public charity or donor-advised fund qualify for a deduction of up to 60% of your adjusted gross income (AGI). Appreciated property gifts are limited to 30% of AGI. Any unused deduction carries forward for up to five additional tax years.
Example: Margaret funds a CRUT with $500,000 of appreciated stock and selects a 5% payout rate. Using the current IRS Section 7520 rate, the projected remainder interest is valued at $280,000. Margaret claims a $280,000 charitable deduction on her federal return. She also avoids the capital gains tax she would have owed if she had sold the stock herself.
Asset Types You Can Contribute to a CRUT
CRUTs accept a wide range of assets, but each type brings different tax consequences and planning challenges.
Cash
Cash is the simplest funding option. It produces an immediate deduction of up to 60% of AGI and creates no capital gains issues inside the trust. Cash-funded CRUTs work well in Standard CRUT structures.
Publicly Traded Stock
Appreciated stock is the most popular CRUT funding asset. The trust sells the stock without paying capital gains tax, reinvests the full proceeds, and the donor receives a deduction based on the stock’s fair market value. The key requirement is that you must have held the stock for more than one year to claim the full FMV deduction.
Real Estate
Real estate works well in a Flip CRUT because the property may not produce enough income to meet the standard payout requirement. The trust sells the property tax-free, and the Flip CRUT converts to a standard payout after the sale. One critical danger: if the property has a mortgage, the debt can generate UBTI inside the trust — triggering the 100% excise tax on the debt-financed income.
Closely Held Business Interests
Private company stock or LLC interests can fund a CRUT, but they require a qualified appraisal and create valuation headaches. The Flip CRUT structure is preferred because closely held interests are illiquid. The trust holds the interest, waits for a sale or redemption, and then flips to a standard payout.
Cryptocurrency and Artwork
These are treated as property by the IRS, not as cash. Cryptocurrency held for more than one year qualifies for the lower capital gains rate. Artwork donated to a CRUT requires a qualified appraisal, and the deduction may be limited to the donor’s cost basis if the charity’s use of the art is unrelated to its exempt purpose. Both asset types add complexity and should involve an experienced tax advisor.
CRUT vs. CRAT: Key Differences
Choosing between a CRUT and a CRAT depends on your financial goals and the assets involved. Here is how the two compare:
| Feature | CRUT | CRAT |
|---|---|---|
| Annual payout | Fixed % of trust value, recalculated yearly | Fixed dollar amount, never changes |
| Additional contributions | Allowed at any time | Not allowed after funding |
| Inflation protection | Yes — payout grows if trust grows | No — payout stays flat |
| Minimum payout rate | 5% of current FMV | 5% of initial FMV |
| Best for | Younger donors, growth-oriented investors | Older donors, income stability seekers |
| Trust variations | Standard, NIMCRUT, Flip | One type only |
| Annual valuation | Required every year | Not required |
A CRUT is the better choice if you expect the trust’s investments to grow over time, because your income grows along with it. A CRAT is simpler and provides predictable income that never changes, which appeals to retirees who want certainty. CRATs are also administratively easier because they do not require annual asset revaluation.
IRS Form 5227: The Annual Filing Requirement
Every CRUT must file IRS Form 5227 — the Split-Interest Trust Information Return — each calendar year. This form is due by April 15 of the following year (with extensions available). Failure to file can result in penalties and IRS scrutiny.
What Form 5227 Covers
The form is broken into several key parts:
- Heading: Trust name, trustee name, address, EIN, and identifying information.
- Part I — Income and Deductions: Reports all income earned by the trust during the year, including interest, dividends, capital gains, rents, and any deductions.
- Part II — Schedule of Distributable Income: This section applies only to Section 664 trusts (CRATs and CRUTs). It tracks the four-tier income categories and determines how distributions are characterized for the beneficiary.
- Part III — Distributions for Charitable Purposes: Reports any payments made to the charitable remainder beneficiary during the year.
- Part IV — Balance Sheet: Provides a snapshot of the trust’s assets, liabilities, and net worth at the beginning and end of the year.
- Schedule K-1 Attachment: Each beneficiary receives a Schedule K-1 (Form 1041) that reports their share of trust distributions, broken down by income type. The beneficiary uses this K-1 to report the income on their personal tax return.
Common Form 5227 Mistakes
Many trustees fail to track accumulated income from prior years in Part II. The four-tier system carries forward undistributed income from every previous year. If you do not maintain accurate running totals of each income category, the K-1 issued to the beneficiary will be wrong — and the IRS will notice.
UBTI: The 100% Excise Tax Trap
A CRUT’s tax-exempt status has one enormous exception. If the trust earns unrelated business taxable income (UBTI), the IRS imposes a 100% excise tax on that income. Every dollar of UBTI is confiscated.
What Creates UBTI
UBTI arises when a tax-exempt entity — including a CRUT — earns income from a trade or business that is not related to its exempt purpose. Common sources include:
- Debt-financed income: If a CRUT holds mortgaged real estate, the rental income attributable to the mortgage is UBTI. Even a portion of the sale proceeds can be tainted.
- Operating a business: If the trust directly operates a business, the profits are UBTI.
- Certain partnership income: If the CRUT invests in a partnership or LLC that runs an active trade or business, its share of that income is UBTI.
There is a $1,000 de minimis exception under IRC Section 512(b)(12). If the CRUT’s total UBTI is $1,000 or less, no excise tax is owed. But once the threshold is crossed, the full amount is taxed at 100%.
The Double-Tax Problem
UBTI gets taxed twice. The trust pays the 100% excise tax when it earns the UBTI. Then, when that income is distributed to the beneficiary, it is taxed again under the four-tier system as ordinary income. This makes UBTI the single most destructive tax event for a CRUT.
How to File
If your CRUT has UBTI, the trustee must file Form 4720 to report and pay the excise tax, in addition to the regular Form 5227 filing.
Self-Dealing and Prohibited Transactions
CRUTs are subject to certain private foundation rules under IRC Sections 4941 through 4945. These rules create strict boundaries around transactions between the trust and “disqualified persons” — which includes the donor, the trustee, family members, and entities they control.
What Counts as Self-Dealing
Prohibited transactions include:
- Selling, exchanging, or leasing property between the CRUT and a disqualified person
- Lending money or extending credit between the trust and a disqualified person
- Furnishing goods, services, or facilities between the trust and a disqualified person (unless provided for free and used for charitable purposes)
- Paying unreasonable compensation from the trust to a disqualified person
The Penalties
The initial tax on an act of self-dealing is 10% of the amount involved for each year the act remains uncorrected, charged to the disqualified person. If the self-dealing is not corrected, a 200% tax applies. The foundation manager (trustee) who knowingly participates faces a 5% penalty up to $20,000 per act. These penalties are in addition to any income tax consequences.
A Real-World Trap
Imagine you create a CRUT and serve as trustee. Your adult child’s company performs accounting services for the trust and charges a fee. Even if the fee is reasonable, this is a prohibited transaction because your child is a disqualified person. The penalty taxes apply regardless of whether the trust benefited from the deal.
Three Real-World Scenarios
Scenario 1: Retiree Funding Retirement Income
Linda, age 68, owns $800,000 in appreciated stock she bought for $200,000. She needs income but dreads the $120,000 capital gains tax bill she would face if she sold. She creates a 5% Standard CRUT with a public charity as the remainder beneficiary.
| What Happens | Tax Result |
|---|---|
| Linda transfers $800,000 in stock to the CRUT | No capital gains tax owed on the transfer |
| CRUT sells the stock for $800,000 | Trust pays $0 in capital gains tax |
| CRUT invests full $800,000 | All proceeds stay in trust, growing tax-free |
| Linda receives 5% payout ($40,000 in year 1) | Taxed under four-tier system on her personal return |
| Linda claims charitable deduction (~$350,000) | Reduces her taxable income for up to 6 years |
| At Linda’s death, remainder goes to charity | No estate tax on remaining trust assets |
Linda avoids $120,000 in capital gains tax, receives a six-figure charitable deduction, and generates more annual income than her stock dividends ever provided.
Scenario 2: Business Owner Selling a Company
David, age 55, owns a closely held business worth $2,000,000 with a cost basis of $300,000. A buyer is interested. If David sells outright, he faces over $340,000 in federal capital gains tax. Instead, he transfers the business interest into a 5% Flip CRUT.
| What Happens | Tax Result |
|---|---|
| David transfers business interest to Flip CRUT | No immediate tax; requires qualified appraisal |
| CRUT operates as NIMCRUT before sale | Minimal or no payouts while asset is illiquid |
| Buyer purchases business from CRUT for $2,000,000 | Trust pays $0 in capital gains tax |
| Flip CRUT converts to Standard CRUT | David begins receiving 5% of trust’s FMV annually |
| David claims charitable deduction (~$700,000) | Offsets other taxable income over several years |
David avoids the immediate capital gains hit, builds a long-term income stream, and receives a deduction worth hundreds of thousands of dollars.
Scenario 3: Real Estate Investor Avoiding Capital Gains
Priya, age 60, owns rental property worth $1,500,000 that she purchased for $400,000. The property is free of any mortgage — a critical detail to avoid UBTI. She is tired of managing tenants and wants passive income. She transfers the property into a 5% Flip CRUT.
| What Happens | Tax Result |
|---|---|
| Priya transfers property to Flip CRUT | No capital gains tax; requires qualified appraisal |
| CRUT collects rental income before sale | Pays net income only (NIMCRUT phase) |
| CRUT sells property for $1,500,000 | Trust pays $0 in capital gains tax |
| Trust flips to Standard CRUT | Priya receives 5% of trust FMV annually (~$75,000) |
| Priya claims charitable deduction (~$550,000) | Reduces taxable income over several years |
If that property had a mortgage, the debt-financed income rules would have triggered UBTI — and the 100% excise tax would have confiscated a portion of the rental income and sale proceeds. Priya avoided this trap by paying off the mortgage before funding the CRUT.
California and State Tax Nuances
Federal law drives most CRUT taxation, but state rules add another layer.
California
California conforms to federal law on CRUTs. A charitable remainder unitrust is exempt from California income tax under the same principles as federal law — except for years when the trust has UBTI. Even though the trust is tax-exempt, it must file California Form 541-B (Charitable Remainder and Pooled Income Trust) every calendar year. If the trust’s first return is being filed, a copy of the trust instrument must be attached.
California beneficiaries pay state income tax on their CRUT distributions at California’s rates, which reach 13.3% for high earners. This is on top of federal tax — making California one of the most expensive states for CRUT beneficiaries.
Other States
Most states follow the federal treatment and exempt the trust itself from state income tax. However, a few states have unique rules around fiduciary income tax, and the beneficiary’s state of residence determines where distributions are taxed. If you live in a state with no income tax — like Texas, Florida, or Nevada — your CRUT distributions face only federal tax.
Mistakes to Avoid
These are the most common — and most expensive — errors CRUT donors and trustees make.
- Funding with mortgaged property. Debt on property inside a CRUT creates UBTI. The 100% excise tax on that income is devastating. Pay off the mortgage before transferring property.
- Failing the 10% remainder test. If the IRS calculates that less than 10% of the initial contribution will reach charity, the trust is invalid from the start. You lose the charitable deduction and all associated tax benefits.
- Setting the payout too high. A 50% payout rate is legal but almost always fails the 10% remainder test. Most successful CRUTs use a 5% to 8% payout rate that balances income with trust longevity.
- Engaging in self-dealing. Any financial transaction between the trust and a disqualified person — even a fair one — triggers penalty taxes under IRC 4941. The penalties apply regardless of intent.
- Forgetting to file Form 5227. The annual filing is mandatory. Missing it can draw IRS penalties and increase audit risk. Every CRUT must file Form 5227 — even in years with no distributions.
- Ignoring state filing requirements. States like California require a separate trust tax return (Form 541-B) even though the trust is tax-exempt. Failing to file can trigger state penalties.
- Not getting a qualified appraisal for non-cash assets. Real estate, closely held stock, artwork, and cryptocurrency all require a qualified appraisal when donated to a CRUT. Without it, the IRS can deny the entire charitable deduction.
Do’s and Don’ts
Do’s
- Do work with an experienced estate planning attorney to draft the trust instrument. A single drafting error can disqualify the entire trust.
- Do use a Flip CRUT for illiquid assets like real estate or business interests. This avoids forced distributions when no cash is available.
- Do pay off all debt on real estate before transferring it to the trust. Mortgaged property creates UBTI.
- Do track accumulated income in all four tiers every year. The trustee’s records must be accurate for Schedule K-1 reporting.
- Do consider the Section 7520 rate when timing your trust creation. A higher 7520 rate means a larger charitable deduction.
- Do name a qualified corporate trustee or independent trustee to avoid self-dealing concerns.
Don’ts
- Don’t use CRUT assets for personal benefit — even temporarily. This is self-dealing and triggers penalty taxes.
- Don’t invest CRUT assets in partnerships or LLCs that generate active business income. This creates UBTI and the 100% excise tax.
- Don’t assume you can change the payout percentage after the trust is created. The rate is locked in the trust instrument.
- Don’t forget that the trust is irrevocable. Once you fund it, you cannot take the assets back.
- Don’t name a non-qualified charity as the remainder beneficiary. The organization must be a 501(c)(3) tax-exempt entity for the deduction to be valid.
- Don’t make additional contributions to a CRAT by mistake — only CRUTs allow additional funding after the initial transfer.
Pros and Cons of a CRUT
Pros
- Tax-free growth inside the trust. The CRUT sells appreciated assets and reinvests the full proceeds without owing capital gains tax.
- Immediate charitable deduction. You reduce your taxable income in the year you fund the trust, with up to five years of carryforward.
- Inflation-adjusted income. Because the payout is tied to the trust’s current value, your income rises if the investments grow.
- Estate tax reduction. The trust assets are removed from your taxable estate, potentially saving your heirs from federal estate tax.
- Flexibility. You can add assets to a CRUT over time, choose from three trust structures, and name multiple charitable beneficiaries.
Cons
- Irrevocable. You cannot undo the trust or reclaim the assets once transferred.
- Income is taxable to beneficiaries. The four-tier system means distributions are taxed — often at ordinary income rates first.
- Administrative burden. Annual valuations, Form 5227 filings, and four-tier income tracking require professional help and cost money.
- UBTI risk. One bad investment that generates UBTI can wipe out an entire year’s income through the 100% excise tax.
- Charity gets the remainder. Your heirs receive nothing from the trust. Some donors pair a CRUT with a wealth replacement trust (funded by life insurance) to offset this.
Gift Tax Considerations
Creating a CRUT does not trigger gift tax if you are the sole income beneficiary. The charitable remainder qualifies for the gift tax charitable deduction. However, if you name someone other than yourself or your spouse as an income beneficiary — such as a child — the present value of that person’s income interest is a taxable gift. You can apply your lifetime unified credit to offset this gift tax.
If both spouses are named as income beneficiaries, there is no gift tax issue between them due to the unlimited marital deduction. But if one spouse dies and the surviving spouse continues receiving payouts, the trust continues as designed.
FAQs
Does a CRUT pay income tax?
No. A CRUT is tax-exempt under IRC Section 664. It pays no federal income tax on investment gains, interest, or dividends earned inside the trust.
Do beneficiaries pay tax on CRUT distributions?
Yes. Beneficiaries owe income tax on every distribution, classified under the IRS four-tier system starting with ordinary income first.
Can I put mortgaged property in a CRUT?
Yes, but it is risky. The mortgage creates debt-financed income classified as UBTI, which triggers a 100% excise tax inside the trust.
Is a CRUT revocable?
No. A CRUT is irrevocable. Once you transfer assets into the trust, you cannot take them back or cancel the arrangement.
Can I be the trustee of my own CRUT?
Yes. You can serve as trustee, but you must follow all fiduciary duties and self-dealing rules to avoid penalty taxes under IRC 4941.
Does a CRUT file a tax return?
Yes. Every CRUT must file IRS Form 5227 annually, even in years when no distributions are made to beneficiaries.
What happens if the CRUT fails the 10% remainder test?
No deduction is allowed. The trust fails to qualify as a valid CRT, and all tax benefits — including the charitable deduction — are lost.
Can I change the charity after creating a CRUT?
Yes, if the trust instrument allows it. Many CRUTs include a provision letting the donor change the charitable remainder beneficiary.
Is there a minimum amount to fund a CRUT?
No legal minimum exists, but most advisors recommend at least $100,000 because administrative and legal costs make smaller trusts impractical.
Does California tax CRUT distributions?
Yes. California taxes CRUT distributions as income to the beneficiary at rates up to 13.3%, on top of federal tax obligations.
