After filing your Articles of Organization with the California Secretary of State, you must adhere to several important state regulatory procedures and legal filings to remain in good standing with the state. One of them is filing Form 568 with the California Franchise Tax Board (FTB).
The LLC Return of Income Form (Form 568) is a state-level return that must be filed with the FTB. It clarifies your LLC’s income, members, deductions, and taxes owed to the state. Filing this form correctly ensures you remain in good standing with the FTB.
In this article, I’ve discussed the main filing requirements, key details, and important due dates to help you better understand how to file and manage California Form 568.

What Is California Form 568?
Form 568 California is a mandatory annual state tax filing required by the FTB. All LLCs operating in the state, whether active, inactive, or earning no income, must file this form each year to remain compliant.
The correct form to file depends on your LLC’s Federal Tax classification (Corporation, partnership, or disregarded entity).
The main reasons for filing Form 568 include:
- Providing key business details (LLC members, ownership percentages, and income distribution).
- Reporting your total income, credits, and deductions for the current taxable year.
- Filing and paying the $800 Annual Franchise Tax.
- Filing and paying the Estimated LLC Fee/Form 3536 (If applicable).
- Reconciling any fee, tax, or credit differences for the current taxable year.
Form 568 ensures you maintain your good standing with the FTB according to the California Revenue and Taxation Code (RTC) §18633.5.
Who Needs To File Form 568?
The state requires most LLCs operating in California to file Form 568 each year. This includes:
- LLCs taxed as a Sole Proprietorship.
- LLCs taxed as a Partnership.
- LLCs taxed as a Qualified Joint Venture.
If you’ve elected to be taxed as a Corporation, you don’t need to file Form 568. You’ll file one of the following forms based on your corporate tax classification instead:
- Form 100 if you’re taxed as a C-Corporation.
- Form 100S if you’re taxed as an S-Corporation.
Important: You do not need to file a tax return or pay the Annual Tax Fee if the following situations apply:
- Your LLC did not conduct state business during the 15 days.
- Your LLC’s taxable year is 15 days or less.
This is set out according to the 2024 Limited Liability Company Tax Booklet of the FTB.

Each form is a complex tax return that depends on several factors. Therefore, I can’t walk you through each one. The application process depends on:
- Your LLC’s tax classification.
- The number of members in your LLC.
- The residency status of your LLC members.
- Your type of business.
- The number of employees in your LLC.
Tip: I recommend that you work with a qualified California accountant who understands the state and Federal tax filing requirements.

Due Date For Filing Form 568
When filing Form 568, the due date depends on how your LLC is taxed and whether it follows a calendar or fiscal accounting year.
1. Calendar Year Vs. Fiscal Year
In a calendar year, the tax year runs from January 1 to December 31.
In a fiscal year, you follow a non-traditional, 12-month accounting period. For example, your fiscal year might run from May 1, 2025, to April 30, 2026
For most LLCs, Form 568 must be filed by March 15th or April 15th each year. This depends on the LLC’s tax classification. I’ve provided a detailed table below for your reference.
Your first Form 568 is due the year after your LLC was approved. For example, your form is due in 2025 if your LLC is approved anytime in 2025.
However, the FTB will automatically grant a 6-7 month filing extension in most cases. This applies to the filing deadline and not the payment. You must pay any fees and taxes owed by the original due date to avoid interest and penalties.
You can check the FTB: Due Date for Business page for more details on the due date and extended due date.
2. What Is The Automatic Filing Extension?
ALL California LLC’s filing Form 568, Form 100, or Form 100S, will be given a 6-7 month filing extension. This is only given as long as your LLC is in good standing with the FTB.
Important: This extension does NOT apply to payment. While you have 6–7 extra months to file, the state requires payment of your Annual Franchise Tax and any other applicable fees to prevent interest and penalties.
The FTB will grant an automatic 6-month filing extension to:
- LLCs taxed as Sole Proprietorships.
- LLCs taxed as Qualified Joint Ventures.
- LLCs taxed as S-Corporations.
The FTB will grant an automatic 7-month filing extension to:
- LLCs taxed as Partnerships.
- LLCs taxed as C-Corporations.
3. Payment For Automatic Extension For LLCs (Form 3537 Or Form 3539)
Remember, the California FTB only grants an automatic extension to the Form 568 filing period, not the payment. Any outstanding fees and taxes owed must be paid by the original due date to avoid interest and penalties.
You must include a payment voucher (Form 3537 or Form 3539) when making a payment. The specific one depends on your LLC’s tax classification.
If your LLC falls under any of these tax classifications, you’ll need to file Form 3537 alongside Form 3537:
- Sole Proprietorships.
- Partnerships.
- Qualified Joint Ventures.
If you’re LLC falls under these tax classifications, you must file Form 3539 with Form 100 or Form 100S:
- C-Corporations.
- S-Corporations.
These additional forms should be used to submit the required payment for the amount of tax reported on Form 568, Form 100, or Form 100S.
- You must submit the payment AND the appropriate voucher form (3537 or 3539) by the original due date if you owe a payment.
- The extension gives you more time to file the paperwork, not make the payment.
Furthermore, you do NOT need to file Form 3537 or Form 3539 if you’re only using the automatic filing extension and do NOT owe a payment. Simply file your LLC return (Form 568, Form 100, or Form 100S) by the extended due date.
Downloading Form 3537 Or Form 3539
You can download Form 3537 and 3539 from the official FTB website:
- Go to the California Franchise Tax Board: Forms and Publications page.
- Click “Search online.”
- Choose the appropriate tax year.
- Select the appropriate tax entity under “Taxpayer type.”
- Click “Get forms.“
- Find Form 3537 or Form 3539.
4. Filing And Extension Due Dates For Form 568, Form 100, And Form 100S
I’ve written a reference table that you can use to review the exact due dates and automatic extension deadlines when filing Form 568, Form 100, or Form 100S.
This depends on your LLC’s tax classification and accounting period.
| Form by tax classification | Initial due date for filing | Extension due date for filing | Due date for payment |
|---|---|---|---|
| 568 (LLC taxed as Sole Proprietorship) | April 15 | October 15 | April 15 |
| 568 (LLC taxed as Qualified Joint Venture) | April 15 | October 15 | April 15 |
| 568 (LLC taxed as Partnership) | March 15 | October 15 | March 15 |
| 100 (LLC taxed as C-Corporation) | April 15 | November 15 | April 15 |
| 100S (LLC taxed as S-Corporation) | March 15 | September 15 | March 15 |
| 568 (LLC owned by another company) | Depends on how the parent LLC is taxed | Depends on how the parent LLC is taxed | Depends on how the parent LLC is taxed |
Following the stated dates in the above table ensures that your returns and payments are filed correctly. This ensures that your LLC maintains its good standing with the California FTB.
Tip: I recommend that you always double-check your specific due dates every year. Weekends, state holidays, or legislative changes may adjust your filing deadlines.
Penalties And Interest For Form 568
Under California law, the FTB imposes strict compliance on all LLC reporting and payment requirements.
You can be faced with significant interest and penalties if you fail to meet any of these obligations. These will accrue until the outstanding balance is paid in full.
You’ll be subject to penalties and/or interest in the following situations:
- Not filing your return.
- Failing to file your return on time.
- Filing your return with incorrect or incomplete information.
I’ve written a summary table below showing the possible interest and penalties that you may be faced with when filing Form 568 and any related payments.
| Penalty name | Form/Obligation | R&TC section | IRC section | Computation/Description |
|---|---|---|---|---|
| Late filing penalty | Form 568 – Your LLC doesn’t file by the due date (Or extension) | R&TC § 19172 | IRC §6698 | LLC’s taxed as Partnerships or similar: – $18 per member per month or part of a month if the return is late (Up to 12 months) |
| Late payment penalty | Form 568 payment (Annual tax, LLC fee) | R&TC § 19132 | IRC § 6651(a)(2) | 5% of the unpaid amount + 0.5% per month (Or part of a month) until paid up to a maximum of 25%. Interest accrues from the due date. |
| Underpayment (10%) penalty | Form 3536 underpayment reconciled on Form 568 | R&TC § 17942(d)(2) | A 10% penalty applies to the difference between the estimated amount and the actual fee owed. The interest runs from the estimated fee due date. | |
| Demand penalty | Form 568 – Failure to file after FTB Demand for Return | R&TC § 19133 | 25% of the total tax or fee due is imposed (Regardless of payments or credits). | |
| Dishonored payment (Bad check) penalty | Payment submitted for Form 568 (Check, e-check, etc.) | R&TC §19134 | IRC §6657 | Payment of $1,250 or less: – $25 or the payment amount, whichever is lower Payment is greater than $1,250: – 2 % of the payment amount (This penalty applies in addition to any other penalties and interest assessed by the FTB). |
| Interest on unpaid tax or fees | All unpaid amounts related to Form 568 | R&TC § 19101 | IRC § 6601 | Daily Interest accrues from the original due date of the return (Or payment due date) until full payment is received. The rate is set quarterly by FTB. |
| Entity suspension/Forfeiture | Failure to file Form 568 or pay the required amounts | R&TC § 23301 | If the LLC fails to comply (File or pay), it may be suspended (Domestic) or forfeited (Foreign). A suspended/forfeited LLC loses rights and privileges until revived. |
Use the FTB’s official resources if you require more detailed penalty information:
Additional Required Forms And Payments When Filing Form 568
You may also be required to include additional forms and payments when filing Form 568. This depends on your LLC’s specific circumstances:
- Your income.
- The number of LLC members.
- The number of employees.
- Your LLC members’ residency statuses.
- Your type of business operations.
I’ve listed the notable forms and payments that you may need to include when submitting Form 568.
1. Form 3832 – Limited Liability Company Nonresident Members’ Consent
You must file Form 3832 (Limited Liability Company Nonresident Members’ Consent) along with Form 568 if you have LLC members who are NOT residents of California.
This form confirms that nonresident members consent to California’s tax laws. Once signed, nonresident members agree that the FTB may tax their share of income from California sources.
Form 3832 ensures that out-of-state members are taxed appropriately if earning income through a California LLC.
Note: You must ensure that Form 3832 is signed and included with all annual filings. This avoids potential processing delays and/or penalties.
a. How To Download Form 3832
Follow these steps to download Form 3832:
- Navigate to the California Franchise Tax Board: Forms and Publications page.
- Click “Search Online.”
- Choose the appropriate tax year under “Tax Year.”
- Choose “Limited Liability Companies” under Taxpayer Type.
- Click “Get Forms.”
- Find Form 3832.
- Click the download link.
2. Schedule K-1 (568): Member’s Share Of Income, Deductions, And Credits
Form Schedule K-1 (568) reports each LLC member’s share of income, deductions, credits, and other items obtained from the LLC’s operations.
Filing this ensures that all LLC members report their California-sourced income correctly on their personal or business tax returns.
One copy of each Schedule K-1 (568) must be attached to Form 568 when it is filed. This is according to the FTB 2024 Limited Liability Company Tax Booklet.
Furthermore, each LLC member must receive a copy of Schedule K-1 (568) to include with their individual or business tax return.
a. How To Download Schedule K-1 (568)
Follow these steps to download Schedule K-1 (568):
- Visit the California Franchise Tax Board: Forms and Publications website.
- Click “Search Online.”
- Under Tax Year, choose the appropriate tax year.
- Under Taxpayer Type, choose “Limited Liability Companies.”
- Click “Get Forms.”
- Find 568 Schedule K-1.
- Click the download link.
3. Form 3536: Estimated LLC Fees
If there is a difference between your estimated income and actual income when filing Form 568, you must pay any remaining LLC fee balance along with your return.
- The FTB will impose a 10% penalty on the underpaid LLC fee if your estimated payment is less than the total amount owed.
- You must include Form 3536 along with Form 568 when filing by mail. This needs to show the amount owed, plus the 10% penalty. Doing this ensures your payment is properly processed and credited to your LLC account by the FTB.
Example: Your tax year runs from January 1, 2025, to December 31, 2025.
- Your estimated 2025 gross receipts are $600,000 using Form 3536.
- You must pay an estimated LLC fee of $2,500 by June 15, 2025.
- Your actual gross receipts are $1,200,000 when filing your 2025 Form 568 on March 15, 2026.
- This results in a total LLC Fee of $6,000.
- You must pay the remaining $3,500 with your return.
- The FTB will impose a 10% penalty on the $3,500 difference since your estimated payment was less than your actual amount owed. This equals $350, bringing your total amount due to $3,850.
Note: You only need to pay the 10% penalty if your estimated payment was made and underpaid. In the case that you didn’t file Form 356 and make an estimated fee payment, you may be faced with interest and other penalties instead.
Read my full article on Form 3536 – Estimated Fee For LLCs for more information regarding due dates, fee schedules, and filing processes.
4. The $800 Annual LLC Tax Fee
You’re required to pay penalties and interest on the unpaid amount if you didn’t pay the $800 Annual LLC Tax by your original due date.
Important: You do NOT need to file Form 3522 again with your return when filing Form 568.
When submitting a late payment, you must send the total amount due. This includes:
- The $800 Annual LLC Tax.
- The late payment penalty.
- The accrued interest.
Include your payment for the total amount due alongside your return if you’re filing Form 568 by mail. This ensures that the FTB are paid accordingly.
Example: Your company, “ABC Designs LLC,” was approved for business in California on March 10, 2025.
- Your first $800 Annual LLC Tax payment is due by June 15, 2025. However, you delayed payment until filing Form 568 on March 15, 2026.
- Your payment is nine months late (From June 15, 2025, to March 15, 2026)
Your late payment penalty is calculated as follows:
- 5% of $800 = $40 (Base penalty).
- 0.5% × 9 months = 4.5% additional ($36).
- Total penalty = $76.
Your total payment is $800 + $76 + interest ($876 + Interest).
Note: You will accrue interest daily from your original due date (June 15, 2025) until full payment is made. The FTB adjusts its rate quarterly, meaning your total amount will vary depending on the rate when you make a payment.
Parent-Child LLC Filing Requirements In California
If you own multiple LLCs, each one is treated as a separate tax-paying entity under California law. This means that each one has its own tax and filing obligations.
This rule applies regardless of whether your parent LLC is formed in or outside of California. Both entities need to comply with the FTB filing regulations to maintain their good standing.
1. Doing Business And Compliance Obligations
Under California Revenue & Taxation Code § 23101, your non-California parent LLC is considered as “doing business in California” if it owns, wholly or partially, a California LLC. The parent LLC is subject to the California Tax laws and filing obligations.
Therefore, your parent LLC must comply with the FTB filing and payment requirements. These include:
- The $800 Annual LLC Tax.
- The Estimated LLC Fee (If applicable).
- Form 568 (LLC Return of Income).
Furthermore, your parent LLC has to register as a Foreign LLC in California. This needs to be done with the California Secretary of State before conducting business in the state.
Failure to comply with these requirements may result in enforcement actions from the California FTB. Potential interest, penalties, and fines for non-payment or non-filing can be issued on the following:
- The $800 Annual Franchise Tax.
- Estimated LLC Fee.
- Form 568 (LLC Return of Income).
On top of this, your parent LLC may face additional penalties for failing to register as a Foreign LLC:
- A $2,000 penalty under California Revenue & Taxation Code § 19135.
- A $20 per day penalty (Up to $10,000 maximum) under California Corporations Code § 2203. This is imposed by the California Secretary of State.
2. Filing And Extension Deadlines For Parent And Subsidiary LLCs
Even when owned by another company, both the Parent LLC and the Child LLC must file their own Form 568.
- Each LLC is treated as a separate taxpayer and must fulfill its own payment requirements and filing obligations.
The automatic filing extensions depend on how the Parent LLC is taxed:
You’ll be given a 6-month filing extension (For your Parent and Child LLC) if your Parent LLC is:
- Taxed as a Sole Proprietorship.
- Taxed as a Qualified Joint Venture.
- Taxed as an S-Corporation.
You’ll be given a 7-month filing extension (For your Parent and Child LLC) if your Parent LLC is:
- Taxed as a Partnership.
- Taxed as a C-Corporation.
These regulations ensure that both LLCs maintain their good standing with the FTB and avoid unnecessary delays and penalties.
California Quarterly Estimated Tax Obligations
If you’re an LLC owner or corporation and you owe state taxes, you’re required to make quarterly estimated tax payments to the FTB. These advanced payments help cover annual tax liabilities and reduce large end-of-year payments or underpayment penalties.
You may still need to make estimated tax payments even if your LLC doesn’t have a regular payroll or withholdings. This depends on how your LLC is taxed and its generated income.
1. Estimated Payments For Individuals
You must make quarterly estimated tax payments using Form 540-ES (Individual Estimated Tax Voucher) if you’re an LLC owner expecting to pay $500 or more in California Income Taxes.
Note: This applies regardless of whether your LLC is taxed as a disregarded entity, partnership, S corporation, or C corporation.
Form 540-ES is used to report and pay income taxes based on an LLC’s projected annual income. This applies to all individuals, including LLC members and partners. These payments are used to cover taxes on business earnings not withheld through the regular payroll.
You can make your estimated payment using:
- FTB Web Pay for Individuals.
- Electronic Funds Withdrawal (EFW).
- Mail Form 540-ES (Include a check or money order payable to the “Franchise Tax Board.”)
These are your quarterly payment due dates:
- April 15.
- June 15.
- September 15.
- January 15 (The following year).
The total estimated payment amount (From all four quarters) must equal at least 90% of your current year’s tax liability/100% of your previous year’s total tax. This avoids potential penalties from the FTB.
Downloading Form 540-ES
Download Form 540-ES from the FTB website using the following steps:
- Visit the California Franchise Tax Board: Forms and Publications page.
- Click “Search Online.”
- Choose the appropriate tax year.
- Select “Individual” under Taxpayer Type.
- Click “Get forms.“
- Look for Form 540-ES.
2. Estimated Payments For LLCs Taxed As Corporations
This requirement applies alongside the individual estimated payments made by LLC members.
Your LLC must also make quarterly estimated tax payments using Form 100-ES (Corporation Estimated Tax Voucher) if you’ve elected to be taxed as a C-Corporation or S-Corporation.
- Form 100-ES is used to pay Franchise or Income taxes in installments throughout the year. This applies to Corporations, including LLCs taxed as corporations.
- These payments prevent underpayment penalties and help LLCs to meet California’s minimum Franchise Tax.
You can submit your payment online using FTB Web Pay for Businesses or by mailing Form 100-ES. You must mail a check or money order to the Franchise Tax Board alongside your form.
Estimated payments are due on the following dates for LLCs following a calendar year:
- April 15 (15th day of the 4th month of the taxable year).
- June 15 (15th day of the 6th month).
- September 15 (15th day of the 9th month).
- December 15 (15th day of the 12th month).
Each of these payments equals 25% of your estimated annual tax. However, corporations may adjust this amount based on their actual income as the year progresses.
I recommend you make all of these payments to remain compliant with the California tax law and keep your good standing with the FTB.
Downloading Form 100-ES
Follow the steps below to download Form 100-ES:
- Visit California Franchise Tax Board: Forms and Publications.
- Click “Search Online.”
- Choose the appropriate tax year.
