What California Form 3538 (565) Is For
California Form 3538 allows a limited partnership to submit an extension payment when it cannot file its partnership return on time. Form 3538 applies to eligible entities, including REMICs and foreign partnerships with income from California sources.
It ensures the Franchise Tax Board credits the payment by the original deadline for the income tax return. The automatic extension grants additional time to file but does not extend the deadline to pay income taxes.
Business entities must meet tax payment obligations to avoid penalties, regardless of return submission timing. Form 3538 satisfies Revenue and Taxation Code requirements without the need to file a separate extension form.
When You’d Use California Form 3538 (565)
Use Form 3538 when a California partnership cannot file its income tax return on time and owes tax. The voucher is necessary during the automatic extension period when business entities still have an unpaid franchise tax.
This includes general partnerships, domestic partnerships, and pass-through entities with business activities or source income in California. You should not use Form 3538 for late filings after the extension or for federal extension filings like Form 7004.
It does not apply to amended returns or to C corporations and S corporations filing Form 100 or Form 100S. If your entity files Form 565 and owes tax, submit payment using Form FTB 3538 during the extension period.
Key Rules or Details for 2014
California grants an automatic extension to file Form 565, but it does not extend the payment deadline. You must pay any tax liability, including the $800 franchise tax, by the original due date.
Late payments trigger penalties under the California Revenue and Taxation Code. Limited partnerships must estimate and pay taxes on income earned from California sources during the extension.
This includes rental income, passive activities, and other items of income reported on Schedule K. Underpayment may result in penalties, interest, or delays in processing your income tax return by the Franchise Tax Board.

Step 1: You must determine your estimated taxable income and the minimum franchise tax owed under California law for the tax year.
Step 2: Confirm that your entity is required to file Form 565 and not Form 568, Form 100, or Form 100S.
Step 3: Enter your entity’s full legal name and Secretary of State file number when completing California Form 3538.
Step 4: Prepare a check, money order, or electronic payment payable to the Franchise Tax Board in the correct amount.
Step 5: Submit Form 3538 and your payment by the original deadline to meet California Revenue and Taxation Code requirements.
Step 6: Keep a copy of the payment record and use it when completing your full partnership return and supporting schedules.
Common Mistakes and How to Avoid Them
Submission errors frequently delay processing and lead to misapplied payments. Identifying specific mistakes and correcting them improves accuracy and ensures compliance with state filing requirements.
- Incorrect Form Usage: This mistake occurs when you file Form 3538 expecting to receive a filing extension. You must use Form 3538 only to make an extension payment. It does not request additional time.
- Missed Payment Deadline: This mistake occurs when you submit the voucher after the original return due date. You must send your payment by the fourth month following your taxable year-end. This satisfies California's payment deadline.
- Mismatched Entity Identification: This mistake occurs when the FEIN or California Secretary of State number is missing or incorrect. You must confirm both identifiers before submitting Form 3538. You should double-check official registration documents before filing.
- Duplicate Payment Submission: This mistake occurs when you file Form 3538 after paying electronically. You must choose one payment method and avoid mailing a duplicate voucher. Electronic payment fulfills the extension payment requirement and does not require filing Form 3538.
- Underreported Payment Amount: This mistake occurs when you pay only the minimum tax without estimating additional liability. You must calculate the full tax liability, including income from California business activities and other reportable earnings. You should use prior-year data to support estimates.
What Happens After You File
After you submit Form 3538 with payment, the Franchise Tax Board processes the payment and applies it to your account. Once posted, the payment reduces your reported tax liability on Form 565 and prevents late payment penalties. You will not receive a confirmation unless you check your bank records or FTB online account.
When completing Form 565, report the extension payment on line 26 to reconcile your account. If your return shows a remaining balance, you must pay that amount when filing. If you overpaid, you may request a refund or apply the credit to next year’s tax.
