How to Fill Out California Form 565 (w/Examples) + FAQs

California Form 565 is the Partnership Return of Income that every general partnership, limited partnership (LP), limited liability partnership (LLP), and Real Estate Mortgage Investment Conduit (REMIC) doing business in California, organized in California, or registered with the California Secretary of State must file each year with the California Franchise Tax Board. The form reports the partnership’s income, deductions, credits, and each partner’s distributive share, and it triggers the $800 annual minimum tax for LPs and LLPs under R&TC §17935.

Missing the deadline or filing an incomplete return is expensive: the FTB charges a per-partner, per-month penalty under R&TC §19172 that adds up fast for partnerships with several partners. The FTB processes more than 250,000 partnership returns each year, and roughly 1 in 7 are flagged for math errors, missing Schedule K-1s, or wrong apportionment, according to FTB e-file statistics.

What the Form Is and Who Must File It

California Form 565 is the state-level partnership income return used to report a partnership’s California-source income, deductions, credits, and partner allocations. The form is required by R&TC §18633, which forces every partnership with a California connection to file an annual information return, even when the partnership has no taxable income. The return is filed with the Franchise Tax Board, not the IRS, and it works alongside the federal Form 1065 that the partnership files with the IRS.

You must file Form 565 if any of these apply during the taxable year. The partnership is organized in California. The partnership is registered with the California Secretary of State. The partnership is doing business in California under R&TC §23101, which includes having California sales over the annual threshold (about $735,019 for 2025), California payroll over $73,502, or California property over $73,502. The partnership has California-source income from rentals, sales, services, or pass-through investments.

LLCs taxed as partnerships do not file Form 565. They file Form 568 instead, even when they are partnerships for federal purposes. Single-member LLCs disregarded for federal tax also file Form 568, never Form 565. REMICs file Form 565 but skip the partner-level schedules and use the REMIC-specific lines.

The form for the 2025 taxable year carries a revision date printed in the lower-left corner of Side 1, and you should always confirm you are using the correct year-stamped version before you start typing. Partnerships with short taxable years still file the current year’s form unless the FTB has not yet released it, in which case you file on the prior year’s form with the new year written at the top.

Before You Start: Documents and Information You Need

Gather every document below before you open the form, because Form 565 cross-references your federal return, your books, and your Secretary of State filings in dozens of places. A missing number forces you to stop, hunt, and restart, and partial entries are the single biggest cause of FTB processing delays.

• Federal Form 1065 (final, signed version). California starts with federal partnership income, so you cannot fill out Side 1 of Form 565 without your completed 1065. A draft 1065 will create mismatches the FTB catches automatically.
• Federal Schedule K-1s for every partner. You will mirror these onto California Schedule K-1 (565), one per partner. Missing a partner’s K-1 triggers the per-partner penalty under R&TC §19172.
• Secretary of State file number (SOS number) and FTB entity ID. Both numbers go on Side 1. Using the wrong one routes your return to the wrong account and causes the FTB to issue a Demand to File notice.
• EIN (federal employer identification number). The FTB matches your EIN against IRS records, and a mismatch holds processing until you respond to a letter.
• Principal business activity code (PBA). The 6-digit NAICS code from your 1065 must match on Form 565. A wrong PBA can flag the return for audit selection.
• Beginning and ending balance sheet. Schedule L on Side 4 requires book values at the start and end of the year. Missing balance sheet figures cause math-check holds.
• California-source income breakdown. If you operate in multiple states, you need apportionment data (sales, payroll, property by state) to complete Schedule R.
• Depreciation schedules and Form 3885P. California depreciation differs from federal in many cases, and you need the Form 3885P reconciliation before you can complete Side 1.
• Partner contact and ownership data. Each Schedule K-1 (565) needs the partner’s name, address, SSN or EIN, percentage interest, and capital account activity.
• Prior-year Form 565 and K-1s. Beginning capital accounts and carryovers come straight from last year’s return.
• Payment voucher FTB 3587. Needed if you owe the $800 annual tax or any balance due by check.

Where to Get the Form and How to Access It

The official 2025 Form 565 PDF is hosted on the FTB’s forms page, and you should always download the current-year Form 565 PDF directly from ftb.ca.gov rather than a third-party site. Third-party copies are often outdated by one or more revisions, and the FTB rejects returns submitted on the wrong-year form. The matching 565 Booklet contains line-by-line instructions and the current apportionment tables.

You can also access Form 565 through any FTB-approved business e-file software, including Lacerte, ProSeries, Drake, UltraTax, and CCH Axcess. The FTB does not allow Form 565 to be filed through CalFile, which is reserved for individual returns. Business e-filing routes through the FTB’s Business e-file program, and approved software handles XML transmission automatically.

Paper filers can print the PDF, complete it by hand or with a fillable PDF editor, and mail it to the FTB. The form is also available in large-print and Spanish-language summary versions on request from the FTB forms line at 800-338-0505. For payment-only access without filing the return, partnerships can use FTB Web Pay for Businesses to send the $800 annual tax or balance due electronically.

If you are amending a prior-year return, you do not use a separate amended form. Instead, you check the Amended Return box at the top of Side 1 on a fresh Form 565 for the year being amended. The FTB keeps prior-year forms back to 2010 on the forms archive, so amendments for older years use the form that was current for that year.

Step-by-Step: How to Fill Out Form 565 Line by Line

Form 565 has four sides plus several schedules and one K-1 per partner. Work through it in the order printed on the form, because later lines pull from earlier ones, and skipping around creates math errors. Use blue or black ink if filing on paper, all capital letters, no dollar signs, and round every entry to the nearest whole dollar.

Side 1, Header: Taxable Year and Entity Information

The top of Side 1 asks for the partnership’s taxable year dates, legal name, address, FEIN, California Secretary of State file number, and principal business activity. Enter the year dates in MM/DD/YYYY format, beginning with the first day of the partnership’s fiscal year. Most partnerships use the calendar year, so they enter 01/01/2025 through 12/31/2025.

Write the partnership’s full legal name exactly as it appears on the Secretary of State filing, in all capital letters. Maria Lopez & Co., A California Limited Partnership must be entered the same way it was registered, because the FTB matches the name against SOS records and rejects mismatches. The street address line accepts a physical address or PMB, and the FTB will accept a P.O. Box only if you also list a physical address on a separate attached statement.

A common mistake on the header is entering the trade name or DBA instead of the legal name, which causes the FTB to issue a Notice of Inconsistency and delay processing by 6–10 weeks. Another common error is leaving the SOS file number blank for general partnerships that never registered, which is fine, but you must then check the box indicating no SOS number was issued. Filers often think the FEIN and SOS number are interchangeable; they are not, and using one in place of the other will route your return to the wrong account.

Side 1, Questions A through K

These checkboxes set the FTB’s expectations for the rest of the return. Question A asks the principal business activity, principal product or service, and 6-digit business code. Use the same NAICS code printed on your federal 1065, such as 531110 for residential rental real estate.

Question B asks whether this is the partnership’s initial return, final return, amended return, or a protective claim. Mark only one box. A common mistake is checking Initial Return in the second year because the partnership did not file in year one; the correct action is to file a late initial return for year one first, because skipping a year can void the LP’s good standing with the Secretary of State.

Question J asks whether the partnership is a passive activity and whether any partner is a disregarded entity. Filers often leave Question J blank, assuming it is optional, but a blank answer triggers an FTB letter asking for clarification before the return can be processed. The misconception that “passive” means “inactive” is wrong; passive here refers to the federal §469 passive activity rules, which apply mainly to rentals and limited partner interests.

Side 1, Line 1 – Gross Receipts or Sales

Line 1 reports total gross receipts or sales from all sources, before returns and allowances. Pull this number directly from federal Form 1065, Line 1a. Enter the gross figure in the left column; do not net out returns yet.

For example, Carlos Mendez, GP of a landscaping partnership with $412,500 in gross billings writes 412,500 on Line 1. If your partnership had no gross receipts but had other income (interest, rents), still enter 0 on Line 1 rather than leaving it blank. A blank Line 1 forces the FTB to manually verify the return, adding weeks to processing.

The common mistake on Line 1 is reporting net receipts (after refunds and discounts) instead of gross. The consequence is that the FTB compares Line 1 to your 1099-K and merchant processing totals, and a low Line 1 triggers a Schedule C-style income discrepancy notice. A common misconception is that exempt sales (like resale-certificate sales) should be excluded; they should not — they belong on Line 1 and are removed later as part of cost of goods sold.

Side 1, Lines 2 through 7 – Other Income Items

Lines 2 through 7 add ordinary income from other partnerships and estates, net farm profit, net gain or loss from Form 4797, and other income. Each line maps directly to a federal 1065 line of the same number. If a line is zero on federal, it is zero on California, with two exceptions: depreciation differences and §179 differences, which California adjusts on Schedule CA-style reconciliations.

A specific example: Riverside Holdings LP has $58,000 of rental income flowing up from a tiered partnership. They enter 58,000 on Line 4. The nuance is that California does not always conform to federal bonus depreciation under IRC §168(k), so the gain on Line 6 (Form 4797) may differ between federal and California by the amount of disallowed bonus depreciation.

The common mistake is copying federal numbers without making the California depreciation adjustment, which understates California income and triggers a Form 3885P reconciliation request. The misconception that “California conforms to federal” is partly false; California has selective conformity with a fixed conformity date, and bonus depreciation, §179 limits, and NOL rules diverge.

Side 1, Lines 8 through 21 – Deductions

The deduction block mirrors federal 1065 Lines 9 through 21. Enter salaries and wages on Line 9, guaranteed payments to partners on Line 10, repairs on Line 11, bad debts on Line 12, rent on Line 13, taxes and licenses on Line 14, interest on Line 15, depreciation (from California Form 3885P) on Line 16a, depletion on Line 17, retirement plans on Line 18, employee benefits on Line 19, and other deductions on Line 20.

Line 21 is the total of Lines 9 through 20, and Line 22 is ordinary business income (Line 8 minus Line 21). For Carlos Mendez, GP, total deductions of $287,300 mean Line 22 reads 125,200 after subtracting from $412,500 of gross income. Round to whole dollars; do not enter cents.

The common mistake here is including the $800 annual tax on Line 14. The annual tax is not deductible on the California return — it is deductible only on the federal 1065, and including it on California Line 14 inflates deductions and understates income. The misconception that “state taxes are deductible everywhere” is wrong for California’s own franchise/annual tax on the California return itself.

Side 2, Schedule A – Cost of Goods Sold

Schedule A applies only to partnerships that sell tangible goods. Service-only partnerships skip Schedule A entirely and enter 0 on Line 2 of Side 1. Inventory partnerships report beginning inventory, purchases, cost of labor, additional §263A costs, other costs, and ending inventory to arrive at cost of goods sold.

For Pacific Surf Apparel LP, beginning inventory was $84,000, purchases totaled $312,000, and ending inventory was $96,000, so cost of goods sold equals 300,000. The Schedule A total flows to Line 2 of Side 1. The nuance is the §263A uniform capitalization adjustment, which forces certain indirect costs into inventory rather than expensing them immediately.

A common mistake is using a different inventory valuation method than the prior year without filing Form 3115 federally. Changing methods without IRS consent disallows the change for California too, and the FTB will recompute COGS using the prior method. The misconception that “FIFO and LIFO are interchangeable each year” is incorrect; you must commit to one method until you formally change it.

Side 2, Schedule B – Partnership Income Reconciliation

Schedule B reconciles federal partnership income to California partnership income line by line, showing every difference caused by depreciation, §179, NOL, and other adjustments. Each line lists a category, the federal amount, and the California amount. Enter both columns even when they are identical.

For example, Riverside Holdings LP reports federal depreciation of $48,200 but California depreciation of $36,500 on Form 3885P, so Schedule B shows the $11,700 add-back. The Schedule B totals must tie to Side 1 totals exactly. A common mistake is leaving the federal column blank “because it’s a California form” — the FTB uses the federal column to validate the reconciliation, and a blank column triggers a manual review.

The misconception that Schedule B is optional for partnerships with no federal-California differences is wrong. Even when amounts are identical, you must complete Schedule B so the FTB can confirm conformity. Skipping Schedule B is a top-five rejection reason for paper returns.

Side 3, Schedule K – Partners’ Distributive Share Items

Schedule K is the partnership-level summary of every income, deduction, and credit item that flows to partners. It mirrors federal Schedule K but with California-specific lines. The totals on Schedule K must equal the sum of the same line across every Schedule K-1 (565) you issue.

Line 1 of Schedule K is ordinary business income from Line 22 of Side 1. Line 2 is net rental real estate income, Line 3 is other net rental income, and so on through Line 21. Carlos Mendez, GP enters 125,200 on Schedule K, Line 1, matching his Side 1 Line 22. The nuance is that California Schedule K has additional lines for state-specific credits like the California Competes Tax Credit and the College Access Tax Credit, which have no federal equivalent.

A common mistake is filling out Schedule K but forgetting to allocate the totals to individual Schedule K-1s, leaving them blank or partial. The consequence is that partners cannot file their own California returns correctly, and the FTB charges the partnership a per-partner penalty of $18 per partner per month under R&TC §19172 for up to 12 months. The misconception that “K-1s are optional if I give partners my numbers verbally” is dead wrong — every partner needs a written, signed Schedule K-1 (565).

Side 4, Schedule L – Balance Sheet per Books

Schedule L is the partnership’s book balance sheet, reported at the beginning and end of the taxable year. It includes cash, accounts receivable, inventories, investments, depreciable assets less accumulated depreciation, intangibles, other assets, liabilities, and partners’ capital accounts. Pull these directly from your accounting software’s trial balance.

For Pacific Surf Apparel LP, ending cash of $42,800, accounts receivable of $19,500, inventory of $96,000, and fixed assets of $138,000 (net of depreciation) produce total assets of 296,300. Total liabilities plus capital must equal total assets to the dollar. A common mistake is forcing a “plug” entry to balance the sheet, which the FTB flags during processing.

The nuance is that partnerships with total assets under $1 million and total receipts under $250,000 can skip Schedule L if they check the box on Question K of Side 1. The misconception that “Schedule L doesn’t matter because it’s not on the tax calculation” is wrong; the FTB uses Schedule L to verify capital accounts on K-1s and to flag suspicious year-over-year jumps that suggest unreported income.

Side 4, Schedule M-1 – Reconciliation of Income (Loss) per Books With Income (Loss) per Return

Schedule M-1 reconciles book net income to tax-return ordinary income. The reconciliation captures permanent and timing differences such as tax-exempt interest, nondeductible meals (50% portion), depreciation differences, and §179 differences. Each line is labeled, and unused lines are entered as zero.

For Riverside Holdings LP, book income of $147,000 plus the $11,700 California depreciation add-back, minus $4,200 of tax-exempt municipal interest, equals tax-return ordinary income of 154,500. The common mistake is forgetting the 50% meals add-back, which understates taxable income and creates a discrepancy with the federal 1065 Schedule M-1.

The misconception that “Schedule M-1 is only for big partnerships” is wrong; every partnership filing Schedule L must also file Schedule M-1, regardless of size, unless it qualifies for the small-partnership exception under Question K.

Side 4, Schedule M-2 – Analysis of Partners’ Capital Accounts

Schedule M-2 tracks total partner capital from the start of the year to the end, including capital contributed, net income or loss, distributions, and other increases or decreases. The ending balance must match the total capital line on Schedule L and the sum of the ending capital accounts on every Schedule K-1.

For a two-partner general partnership where beginning capital was $80,000, partners contributed $20,000 additional, the partnership earned $125,200 of ordinary income, and distributions totaled $90,000, ending capital is 135,200. A common mistake is reporting tax-basis capital on M-2 but GAAP-basis capital on Schedule L; the two must use the same basis, and the FTB requires tax-basis capital reporting for partnerships starting with the 2020 taxable year, consistent with the federal rule.

The misconception that “distributions reduce taxable income” is a classic error; distributions reduce capital accounts but never reduce ordinary income on Line 22 of Side 1.

Schedule K-1 (565) – Partner’s Share of Income, Deductions, Credits

Each partner gets a Schedule K-1 (565) showing their share of every Schedule K item. The K-1 lists the partner’s identifying information, percentage interest, capital account activity, and line-by-line distributive share. You file copies of every K-1 with the FTB and give one to each partner.

For Maria Lopez, a 50% general partner in a $125,200-income partnership, her K-1 shows 62,600 on Line 1 (ordinary business income), her capital contributions, her share of distributions, and her ending capital account. The nuance is that nonresident partners require the partnership to either withhold California tax under R&TC §18662 at 7% of distributions, or to receive a signed Form 589 waiver, or to file a group return.

A common mistake is rounding percentages so the K-1 totals do not equal Schedule K totals. The misconception that “California uses federal K-1 numbers” is partly false — California K-1s often differ because of depreciation, §179, and credit adjustments.

Schedule R – Apportionment and Allocation of Income

Schedule R is required for any partnership with income from sources both inside and outside California. The schedule computes the California apportionment percentage using a single-sales-factor formula for most businesses under R&TC §25128.7. Multiply total business income by the California sales factor to get California-source business income.

For a multistate LP with $4 million of total sales and $1.6 million of California sales, the apportionment percentage is 40%. If business income is $500,000, California-source business income is 200,000. Nonbusiness income (rents from a specific California property, gains from a California building) is allocated directly to California, not apportioned.

The common mistake is treating intangible income (royalties, interest) as nonbusiness and allocating it to the home state when it actually relates to the California business operations. The misconception that “single sales factor doesn’t apply to partnerships” is wrong — it applies to most partnerships, with narrow exceptions for certain agricultural, extractive, and banking partnerships that still use the three-factor formula.

Annual Tax Line and Payment Voucher FTB 3587

LPs, LLPs, and REMICs owe the $800 annual tax under R&TC §17935 and §17948 even if they have no income. General partnerships do not owe the $800 tax. The annual tax is due by the 15th day of the 4th month of the taxable year (April 15 for calendar-year filers), separate from the return’s due date.

Pay using FTB Form 3587 or electronically through Web Pay. A common mistake is paying the $800 with the return instead of by the 4th-month deadline, which triggers a late-payment penalty plus interest under R&TC §19132. The misconception that “the $800 is deductible on California” is wrong — it is deductible federally but not on California Form 565 itself.

How to File the Completed Form

Form 565 can be filed electronically through any FTB-approved business e-file software, by mail on paper, or in person at an FTB field office. Electronic filing is required for partnerships with more than 100 partners under R&TC §18621.10, and the FTB strongly prefers e-file for all partnerships because it cuts processing time roughly in half.

E-file (preferred): Use any FTB-approved software listed on the Business e-file providers page. The software transmits the return in FTB XML format, and you receive an acknowledgment within 24–48 hours. There is no FTB e-file fee, though software vendors charge their own fees ranging from about $30 for self-prep tools to several hundred dollars for professional packages. Payment with the return is made by ACH debit through the software; keep the acknowledgment PDF as your proof of filing.

Paper (mail): If you owe a balance due (rare for partnerships), mail to Franchise Tax Board, P.O. Box 942857, Sacramento, CA 94257-0501. If you have no balance due, mail to Franchise Tax Board, P.O. Box 942857, Sacramento, CA 94257-0531. Use first-class mail with tracking, or certified mail with return receipt, and keep the green card as proof of filing date. Paper processing takes 8–12 weeks.

Payment-only channels: The $800 annual tax can be paid by Web Pay (free ACH debit), by credit card through ACI Payments (2.3% fee), or by check with FTB 3587. Web Pay confirmations should be screenshot or printed.

Due dates: Calendar-year returns are due March 15, 2026 for tax year 2025. The FTB grants an automatic 7-month extension to October 15, 2026, with no form required if no payment is owed. If the $800 annual tax is unpaid, file Form 3538 with payment to keep the extension valid.

What Happens After You File

Once the FTB receives your Form 565, an automated system runs math checks, federal-state cross-checks, K-1 totals against Schedule K totals, and Schedule L balance verification. E-filed returns receive an acknowledgment within 24–48 hours, while paper returns sit for 6–10 weeks before initial processing. If the return passes automated checks, the FTB posts it as filed on the partnership’s account.

If the return fails an automated check, the FTB issues a Return Information Notice (RIN) requesting clarification, missing schedules, or corrected K-1s. You typically have 30 days to respond. Common RIN triggers include missing K-1s, Schedule L imbalance, Schedule R apportionment errors, and unpaid annual tax.

The FTB may also select returns for examination based on risk scoring, large depreciation deltas, or anomalous balance sheet jumps. An FTB partnership examination typically begins with an Information and Document Request (IDR) and proceeds through field or correspondence review. Partnerships have full appeal rights through the Office of Tax Appeals.

Partners receive their K-1 (565) and use it to file their own California returns — Form 540 for residents, Form 540NR for nonresidents, or Form 100/100S for corporate partners. If the partnership amends Form 565 later, every partner must receive an amended K-1, and partners may need to amend their own returns.

Mistakes to Avoid When Filling Out the Form

The list below covers the ten most common errors the FTB sees on Form 565. Each error has a one-line description and a one-line consequence so you can spot and fix it before filing.

• Filing Form 565 when you should file Form 568. LLCs taxed as partnerships file 568, not 565; the FTB rejects the wrong form and you must refile, sometimes after the deadline.
• Missing the $800 annual tax payment by the 4th-month deadline. Late annual tax triggers a 5% late-payment penalty plus interest under R&TC §19132.
• Leaving Schedule K-1s incomplete or unsigned. Triggers per-partner penalty of up to $216 per partner under R&TC §19172.
• Wrong NAICS business code. Mismatched codes can flag the return for audit selection and delay refunds.
• Reporting GAAP-basis capital accounts on Schedule M-2 instead of tax-basis. Causes K-1 totals to disagree with Schedule L and triggers a Return Information Notice.
• Treating the $800 annual tax as deductible on Form 565. Inflates deductions; the FTB recomputes income and assesses tax plus interest.
• Skipping Schedule R for multistate operations. Without apportionment, the FTB assumes 100% California sourcing and assesses tax on the full amount.
• Using a draft federal 1065 instead of the final filed 1065. Numbers do not match IRS records and the FTB holds processing pending reconciliation.
• Forgetting Form 589 waivers for nonresident partners. Triggers 7% withholding on distributions under R&TC §18662, billed back to the partnership.
• Filing the wrong-year version of the form. The FTB rejects mismatched-year returns; if the rejection happens after the deadline, late-filing penalties apply.

Do’s and Don’ts

These six do’s and six don’ts compress the highest-leverage practices from 30 years of partnership filing into a quick checklist. Each carries a brief explanation of why it matters.

Do’s: – Do file electronically whenever possible, because e-file cuts processing time and gives you a same-day acknowledgment. – Do download the form directly from ftb.ca.gov, so you have the current revision with the correct year stamp. – Do reconcile Schedule K totals to the sum of all K-1s before filing, because mismatches are the top automated-rejection reason. – Do pay the $800 annual tax by the 15th day of the 4th month, separately from the return, to avoid late-payment penalties. – Do keep tax-basis capital accounts consistently year over year, because changing basis triggers FTB letters and partner confusion. – Do save digital copies of every K-1 you issue, because partners lose them and request reissues for years afterward.

Don’ts: – Don’t deduct the $800 annual tax on the California return, because the deduction is federal only. – Don’t file Form 565 for an LLC taxed as a partnership — file Form 568 instead, because the FTB treats them as completely different entities. – Don’t skip Schedule B even when federal and California are identical, because the FTB requires the reconciliation regardless. – Don’t round capital accounts to neat percentages if real percentages are uneven, because the sum of K-1s must equal Schedule K exactly. – Don’t mail returns without tracking, because lost-mail disputes are nearly impossible to win without delivery proof. – Don’t ignore an FTB Return Information Notice, because failure to respond within 30 days converts the proposed adjustment into a final assessment.

Pros and Cons of Filing on Your Own vs. With Help

Many partnerships face a choice between filing Form 565 themselves with off-the-shelf software and hiring a CPA or enrolled agent. The right answer depends on the partnership’s complexity, number of partners, and multistate footprint.

Pros of filing on your own: – Pro: Lower direct cost, because self-prep software runs $30–$200 versus $800–$3,000 for professional preparation. – Pro: Faster turnaround for simple partnerships with two partners and one state. – Pro: Direct control over data entry, which reduces communication errors. – Pro: Builds in-house tax knowledge that helps with quarterly estimates and bookkeeping. – Pro: No reliance on a preparer’s schedule near the March 15 deadline.

Cons of filing on your own: – Con: Apportionment errors are common for multistate partnerships and expensive to fix. – Con: Nonresident withholding rules are easy to miss, which exposes the partnership to FTB billbacks. – Con: K-1 capital account rules changed in 2020 and trip up many self-filers. – Con: California’s selective conformity to the IRC creates depreciation traps that automated software does not always catch. – Con: No professional standing to represent the partnership in an FTB exam, which forces hiring a preparer mid-audit at higher rates.

FAQs

Who is required to file California Form 565?

Yes — every general partnership, LP, LLP, and REMIC organized in California, registered with the Secretary of State, or doing business in California must file Form 565 each year under R&TC §18633.

Do LLCs file Form 565?

No — LLCs taxed as partnerships file Form 568, not Form 565, even though they are partnerships for federal tax. Filing the wrong form causes rejection.

Is the $800 annual tax required for general partnerships?

No — general partnerships do not owe the $800 annual tax. Only LPs, LLPs, and REMICs owe it under R&TC §17935 and §17948.

When is Form 565 due for the 2025 taxable year?

Yes — the calendar-year due date is March 15, 2026, with an automatic 7-month extension to October 15, 2026, if no balance is due.

Do I write the legal name or the DBA on the entity name line of Side 1?

Yes — write the legal name exactly as registered with the Secretary of State. Using the DBA triggers a name-mismatch notice and processing delay.

Should I leave the SOS file number blank if my general partnership never registered?

Yes — leave it blank and check the box indicating no SOS number was issued. General partnerships are not required to register with the SOS.

Do I check “Initial Return” on Question B if I forgot to file last year?

No — check Initial Return only in the partnership’s true first year. File the missed year first, then mark the current year as a continuing return.

Is Question J (passive activity) optional?

No — Question J must be answered. A blank answer triggers an FTB clarification letter and delays processing.

Can I file Form 565 through CalFile?

No — CalFile is for individual returns. Business returns file through FTB-approved e-file software listed on the Business e-file providers page.

Are paper-filed Form 565 returns still accepted?

Yes — paper filing is accepted, but partnerships with more than 100 partners must e-file under R&TC §18621.10. Paper processing takes 8–12 weeks.

Do nonresident partners need to be on a withholding return?

Yes — unless a signed Form 589 waiver is on file, the partnership must withhold 7% on distributions to nonresidents under R&TC §18662.

Can I deduct the $800 annual tax on Form 565?

No — the $800 annual tax is deductible federally on Form 1065 but is not deductible on the California Form 565 itself.

Do I need to file Schedule L if my partnership is small?

No — if total assets are under $1 million and total receipts are under $250,000, you can skip Schedule L by checking the small-partnership box on Question K of Side 1.

Does California follow federal bonus depreciation?

No — California does not conform to federal bonus depreciation under IRC §168(k), so depreciation must be recomputed on Form 3885P and reconciled on Schedule B.
