Where do i mail form 568 is one of the most common questions asked by California limited liability company owners at tax time, because the answer depends on details that change from year to year and the wrong address can delay a return. Form 568 is the California Limited Liability Company Return of Income, filed with the California Franchise Tax Board, and the correct mailing address depends on whether you are sending a payment with the return or filing without one, and on the instructions for the tax year in question. This guide explains how to find the current, correct address through official channels, without guessing and without relying on an address copied from an old blog post.
Where Do I Mail Form 568?
The safest rule is simple: always use the mailing address printed in the official Form 568 instructions for the tax year you are filing, which are published on the Franchise Tax Board’s website. Addresses for tax agencies do change, and a street address that was correct two years ago may now route your return to the wrong processing centre. The Franchise Tax Board also offers electronic filing for many LLC returns, which removes the mailing question entirely and gives you a confirmation that the return was received. If you do mail a paper return, use a trackable delivery method so you can prove when it was sent.
What Form 568 Is and Who Files It
Form 568 is the annual tax return that most California LLCs must file, reporting the company’s income, deductions and credits for the year, and it is separate from the annual franchise tax and LLC fee that California charges. Most LLCs that are organised in California, or that do business in the state, need to file it each year, even in years when the business had little or no activity, although there are limited exceptions that the Franchise Tax Board’s guidance describes. The return is filed for the tax year, and the due date generally follows the standard schedule for the entity type, with extensions available under the rules the board publishes.
Because the form covers a whole year of business activity, it is worth preparing it from complete records rather than rushing it at the deadline: profit and loss statements, member information, and details of any payments already made. Many small LLCs use a tax professional for this return, which is often sensible given California’s separate franchise tax and fee calculations, but owners who file themselves should work from the official instructions rather than from summaries. For general guidance on where tax returns are sent, our guide to mailing tax returns explains the same official-channel principle for federal filings.
How to Find the Current Mailing Address
Finding the current answer to where do i mail form 568 starts on the Franchise Tax Board’s website, where the Form 568 booklet for your tax year lists the mailing addresses for returns with and without payments. Download the booklet that matches your filing year, not the most recent one by default if you are filing a late or amended return, because the addresses can differ between years. Inside the booklet, the mailing section distinguishes between returns that include a payment and returns that do not, and using the wrong one is the most common cause of processing delays.
If you cannot find the booklet, the Franchise Tax Board’s phone and online help services can point you to the right address, and its website also lists addresses by form and tax year. Double-check the address you write on the envelope against the booklet before posting, and keep a copy of the return and the proof of mailing. It is also worth confirming whether your return can be filed electronically, since the board’s e-file programme accepts many LLC returns and eliminates the risk of a misdirected envelope altogether. Remember that this article gives general guidance only and is not tax advice for your specific situation.
Payment or No Payment: Why It Matters
The distinction between mailing a return with a payment and mailing one without a payment matters because tax agencies route these envelopes to different processing centres. A return with a cheque or money order goes to a payment processing unit, while a return without payment goes to a returns processing unit, and sending either to the wrong centre means it must be forwarded internally, which takes time. In the worst case, a payment sent to the wrong address may not be credited promptly, which can lead to notices and penalties even though you posted on time.
To avoid that, decide first whether you owe anything with the return, then pick the matching address from the official instructions, and write the form number and tax year on your payment if you include one. If you pay electronically through the board’s payment system, you may still need to mail the return itself to the no-payment address, so check the instructions for that combination too. Using certified or tracked mail gives you a record of the posting date, which matters because California generally treats a return as filed on the postmark date. Keep that receipt with your tax records for at least the period the board recommends.
Common Mistakes When Asking Where Do I Mail Form 568
The most common mistake behind where do i mail form 568 searches is copying an address from an outdated source, such as a forum post or an article written for a different tax year. Tax agency addresses, processing centres and even form numbers change, so any address that is not taken from the current year’s official instructions should be treated as suspect. Another frequent error is mailing a California return to a federal address, or vice versa: Form 568 goes to the California Franchise Tax Board, not to the federal tax agency, and the two systems are entirely separate.
Other mistakes include forgetting to sign the return, omitting the LLC’s entity number, and failing to include the correct payment voucher when one is required. An unsigned return is not considered filed, and a missing voucher can delay the crediting of a payment. Before sealing the envelope, run through a short checklist: correct year booklet, correct payment or no-payment address, signature, entity number, and a copy kept for your records. If anything is uncertain, the Franchise Tax Board’s guidance pages and helpline are the authoritative source, and a tax professional can confirm the details for a complex return.

Frequently Asked Questions
Can I mail Form 568 to the IRS?
No. Form 568 is a California return and goes to the California Franchise Tax Board, not to the federal tax agency.
Does the mailing address change every year?
It can change, which is why you should always use the address in the official instructions for the tax year you are filing.
Is electronic filing available for Form 568?
The Franchise Tax Board accepts many LLC returns electronically; check its e-file programme for eligibility and confirmation.
Filing Deadlines, Extensions and Late Returns
Knowing where do i mail form 568 is only half the task, because the return also has to arrive on time, and California’s deadlines and extension rules catch many LLC owners out. The standard due date for Form 568 follows the schedule published by the Franchise Tax Board for the tax year, and LLCs that need more time can generally obtain an automatic extension by following the board’s extension procedure, although an extension to file is not an extension to pay any tax or fee due. Interest and penalties can still apply to amounts paid late, so owners who expect to owe should arrange payment by the original due date even if the return itself will follow later.
Late returns create their own complications, because the mailing address in the current year’s booklet may not be the right one for an older tax year, and the board’s instructions for prior years are published separately. If you are filing a return that is several years late, download the booklet for that specific year and use the address it lists, and consider whether the board’s voluntary compliance or penalty relief options apply to your situation. Keeping copies of every return, payment voucher and proof of mailing is especially important for late filings, since the board may ask for evidence of when a return was sent and what it contained.
Amended returns follow a similar principle: use the instructions for the year being amended, mark the return as amended in the way the booklet describes, and explain the changes clearly so the processing centre can match the amendment to the original filing. If you are unsure about any of these steps, a California tax professional can confirm the deadline, the address and the extension rules for your entity, and the cost of that advice is usually far less than the penalties for a misdirected or late return. The Franchise Tax Board’s website remains the authoritative source, and its guidance pages are updated whenever deadlines or addresses change.
Conclusion
The answer to where do i mail form 568 is always found in the same place: the official Form 568 instructions for your tax year on the Franchise Tax Board’s website, choosing the payment or no-payment address as appropriate. Do not trust an address copied from an old article, keep a copy of everything you send, and use tracked mail so you can prove the posting date. Better still, check whether you can file electronically and remove the envelope from the equation entirely. See also our California tax mailing addresses.
