California Form 568 is the Limited Liability Company Return of Income that every LLC classified as a partnership or disregarded entity, and registered or doing business in California, must file each year with the California Franchise Tax Board. The form reports the LLC’s income, calculates the $800 annual tax and the graduated LLC fee, and lists each member’s share of California-source income on Schedule K-1 (568).
Roughly 2.6 million LLCs are registered with the California Secretary of State, and the FTB processes well over a million Form 568 filings each year, with a rejection or correction rate near 12% on paper returns according to FTB processing reports. Getting this form wrong can cost real money, because the late-filing penalty under R&TC §19131 stacks on top of the per-member penalty under §19172.

What Form 568 Is and Who Must File It
Form 568 is California’s combined return for LLCs that are not taxed as corporations for federal purposes. It serves three jobs at once: it calculates the $800 annual tax under R&TC §17941, it calculates the LLC fee under §17942, and it reports each member’s share of income on Schedule K-1 (568). The form covers the 2025 tax year and carries a revision date printed in the lower-left corner of page 1, which the FTB updates each January.
Every LLC classified as a partnership for federal tax purposes must file Form 568 if it is organized in California, registered with the Secretary of State, doing business in California under §23101, or has California-source income. A single-member LLC owned by an individual still files Form 568, even though it is a disregarded entity for federal income tax. The owner reports the SMLLC’s income on a personal Form 540 or 540NR, but the $800 annual tax and the LLC fee still flow through Form 568.
LLCs taxed as corporations file Form 100 or Form 100S instead, not Form 568. Foreign LLCs registered with the California SOS owe the $800 even with zero California activity, a rule softened only by the Swart Enterprises decision, which held that a passive 0.2% member with no California presence was not “doing business” here. The takeaway is simple: registration with the SOS, not just income, can pull an LLC into the Form 568 net.
Before You Start: Documents and Information You Need
Filing Form 568 goes faster when you gather everything first. The form pulls numbers from your federal return, from your books, and from California-specific schedules, and missing any of these inputs is the top reason filers stall halfway through.
Here is a pre-filing checklist with at least eight items, each tied to a reason the FTB cares:
- Federal Form 1065 (or Schedule C for an SMLLC) because Form 568 starts with federal taxable income and adjusts from there.
- Articles of Organization or Application to Register, since the 12-digit Secretary of State file number must match SOS records exactly.
- Federal EIN confirmation letter (CP 575) because a missing or wrong EIN routes your return to the FTB’s error-resolution unit and freezes processing for weeks.
- California sales records and apportionment data, including everywhere your LLC sold goods or performed services, because Schedule R and Schedule IW depend on it.
- Each member’s full legal name, SSN or ITIN or FEIN, address, and ownership percentage for Schedule K-1 (568).
- Prior-year Form 568 and any FTB notices, so you can carry forward credits and match the prior-year capital account balances.
- Proof of $800 payment via FTB 3522 for the current tax year, due the 15th day of the 4th month after formation.
- Estimated LLC fee voucher FTB 3536 if your prior-year fee was over $0, because California requires the fee paid by the 15th day of the 6th month.
- Bank statements and merchant processor reports, since “Total Income from all sources” on Schedule IW must reconcile to deposits.
- Schedule EO (568) information for any pass-through entity owners or disregarded entities owned by the LLC.
If any item is missing, stop and gather it before you keep going. Filing with bad data triggers an FTB Notice of Tax Return Change, and fixing one is far slower than getting it right the first time.
Where to Get the Form and How to Access It
The official 2025 Form 568, its instructions booklet, and every related schedule live on the FTB’s forms and publications page. Always download the PDF directly from ftb.ca.gov, not from a third-party site, because older versions of the form are rejected when the line numbers no longer match the current year.
You can also access Form 568 through approved tax software such as TurboTax Business, Lacerte, ProSeries, Drake, and CCH Axcess, all of which carry the FTB’s e-file approval. The FTB lists every approved vendor on its e-file providers page, and using one is usually the fastest path because the software validates math, format, and SOS file number before transmission.
Paper filers can request a printed copy by calling the FTB’s forms line at 800-338-0505. CPAs and enrolled agents typically pull the form through their professional software, which auto-populates from the federal 1065 or Schedule C. New LLCs in their first short year still use the same Form 568, but check the Initial Return box at the top of page 1, a box many first-timers miss.
Step-by-Step: How to Fill Out Form 568 Line by Line
This is the heart of the article. Work through page 1 first, then the schedules in the order printed on the form. Use the exact field names and box numbers shown on the official 2025 Form 568.
Tax Year and Fiscal Year Boxes (Top of Page 1)
The very top of Form 568 asks for the taxable year — either the calendar year 2025 or a fiscal year with start and end dates. Enter the dates in MM/DD/YYYY format with no dashes or extra spaces.
A calendar-year LLC writes 01/01/2025 and 12/31/2025 in the fiscal-year boxes, or simply leaves them blank and relies on the preprinted 2025 in the masthead. A fiscal-year LLC running July 1 to June 30 writes 07/01/2025 and 06/30/2026.
For example, Maria Lopez’s single-member LLC, Lopez Coastal Marketing LLC, runs on a calendar year, so she leaves the fiscal-year boxes blank. The nuance to watch: if your LLC formed mid-year, your first return is a short period, and you must still write the actual organization date as the start, not January 1.
A common mistake is writing the wrong year because last year’s PDF was reused. The consequence is that the FTB rejects the e-file or routes the paper return to manual review, which can delay your $800 payment posting and trigger a late-payment penalty. The misconception many filers carry is that the year on the form refers to the year of filing — it does not. It refers to the taxable year being reported.
LLC Name, DBA, and Address Block
This block asks for the LLC’s exact legal name, any DBA, the street or PO box, the city, the state, the ZIP, and the foreign country if applicable. Write the legal name exactly as it appears on the Articles of Organization, in all capital letters, with no abbreviations the SOS did not use.
For example, LOPEZ COASTAL MARKETING LLC is the correct entry, while “Lopez Coastal” or “Lopez Coastal Marketing, L.L.C.” would mismatch SOS records. A PO box is allowed, but if you also have a physical address you want on file, use the Principal Business Activity line and an attached statement to clarify.
The most common mistake is using the trade name instead of the legal name. The consequence is that the FTB cannot match the return to the SOS file number, and your return sits in a suspense queue. The misconception is that punctuation does not matter; in fact, the FTB matches character-for-character, so commas and periods count.
California Secretary of State (SOS) File Number
This 12-digit number was assigned when the LLC registered with the California Secretary of State. It begins with two zeros for older LLCs or with 2, 3, or 4 for newer ones, and it is printed on the Articles of Organization stamped copy.
Enter the number with no dashes, no spaces, and no leading letters. 201912510123 is the correct format. If you cannot find your number, look it up on the SOS BizFile portal using the LLC name.
A common edge case is a foreign LLC that registered with California after forming in another state — that LLC still has a California SOS number assigned at registration, and that is the number to use. The mistake to avoid is entering the federal EIN in the SOS box, which guarantees rejection. The misconception is that the SOS number is optional for SMLLCs; it is not.
Federal Employer Identification Number (FEIN)
The FEIN is your nine-digit federal EIN, formatted XX-XXXXXXX. Disregarded SMLLCs that have no employees and no excise tax filings sometimes operate under the owner’s SSN federally, but California still expects an EIN if the LLC has one.
Enter exactly what is on your IRS CP 575 letter. For example, Lopez Coastal Marketing LLC enters 87-1234567.
The edge case: an SMLLC owned by an individual that has never obtained an EIN may enter the owner’s SSN, but only if no EIN exists. The mistake is transposing two digits, which causes the FTB’s matching system to flag the return. The misconception is that the EIN field is the same as the SOS number — it is not, and confusing the two is a common reason returns get rejected.
Principal Business Activity Code
This six-digit NAICS code describes what the LLC does. Use the same code reported on federal Form 1065 line A or Schedule C line B, and pull from the IRS Principal Business Activity Codes list.
For example, a marketing consultancy enters 541613. A short-term rental LLC enters 721199. Write the code in the boxes provided, plus the plain-English description on the next line, such as MARKETING CONSULTING.
The edge case is an LLC with two material business lines; pick the one producing the most gross receipts. The mistake is using last year’s code when the business pivoted, which can mislead the FTB’s risk-scoring system. The misconception that this field is cosmetic is wrong — California uses NAICS codes to test whether a single-sales-factor or three-factor apportionment applies.
Question A — Initial Return, Final Return, Amended Return
Question A is a row of check boxes at the top of page 1. Check Initial Return if this is the LLC’s first Form 568. Check Final Return if the LLC dissolved, cancelled, or merged out of existence. Check Amended Return if you are correcting a previously filed return.
For example, Lopez Coastal Marketing LLC, formed in March 2025, checks Initial Return on its 2025 filing. A multi-member LLC that cancelled with the SOS in November 2025 checks Final Return and attaches a copy of the SOS Form LLC-4/7.
The mistake to avoid is forgetting to check Final Return on the year you cancel, which keeps the LLC on the FTB’s active rolls and triggers another $800 the following year. The misconception is that an amended return needs a separate form; it does not, you check the Amended box on Form 568 itself and attach an explanation.
Question K — Series of Yes/No Boxes
Question K on page 2 is a series of yes/no questions about the LLC’s activities, ownership, and California connections. Each question has a real consequence. Answer truthfully, because false answers expose the LLC to the fraud penalty under R&TC §19164.
For example, Question K(1) asks whether the LLC is a member of another LLC; if yes, attach Schedule EO (568). Question K(4) asks about disregarded entities owned by the filing LLC. Question K(6) asks about transfers of California real property interests, which can trigger withholding under §18662.
The mistake is checking No by reflex when the answer is genuinely Yes. The consequence is a mismatch between Form 568 and other FTB filings, such as Form 593 real estate withholding, which produces an automated discrepancy notice. The misconception is that Question K is a formality — it is not, and FTB auditors use it as a roadmap.
Line 1 — Total Income from Schedule IW
Line 1 on Side 1 reports Total California Income from Schedule IW, which is the Limited Liability Company Income Worksheet on page 7 of the form. Schedule IW combines California-sourced gross receipts, gross rents, gross dividends, and other income items.
For example, if Pacific Coast Builders LLC has $1,250,000 of California gross receipts and $0 of California rental income, Line 1 reads 1,250,000. Round to whole dollars, no cents.
The edge case is an LLC with mixed California and out-of-state activity; only the California portion goes on Line 1, after Schedule R apportionment if applicable. The mistake is entering federal gross receipts; California’s number can be lower or higher depending on apportionment. The misconception is that Line 1 equals Form 1065 Line 1c — it usually does not.
Line 2 — Limited Liability Company Fee
Line 2 is the graduated LLC fee based on the bracket your Total California Income on Line 1 falls into. The 2025 brackets, set by R&TC §17942, are: $0 if income is under $250,000; $900 from $250,000 to $499,999; $2,500 from $500,000 to $999,999; $6,000 from $1,000,000 to $4,999,999; and $11,790 for $5,000,000 or more.
For example, Pacific Coast Builders LLC with $1,250,000 of California income owes a $6,000 fee. Write 6,000 on Line 2.
The mistake is using federal gross income to pick the bracket; the California-only number controls. The consequence is either underpayment of the fee, which triggers a 10% penalty under §17942(d), or overpayment that ties up cash for months. The misconception is that the fee scales linearly — it does not, it jumps in tiers, so being one dollar over a bracket can cost thousands.
Line 3 — 2025 Annual Limited Liability Company Tax
Line 3 is always $800 for any LLC that exists for any part of the tax year. This is the annual tax under R&TC §17941, and it is owed even if the LLC had zero income.
Write 800 on Line 3. There is no proration for short years, except for LLCs that organized after the first-year exemption sunset on January 1, 2024.
The edge case is an LLC that filed Articles of Cancellation within 12 months of forming and never did business; in that narrow case, no $800 is owed. The mistake is assuming a dormant LLC owes nothing, which is wrong. The misconception is that the $800 is paid through Form 568 — it is actually paid separately via FTB 3522 by the 15th day of the 4th month, and Line 3 just records the obligation.
Line 4 — Nonconsenting Nonresident Members’ Tax
Line 4 captures California tax withheld on nonresident members who did not sign a Nonresident Consent Form 3832. The rate is the highest individual rate, currently 12.3%, applied to each nonresident member’s distributive share of California-source income.
For example, if Pacific Coast Builders LLC has a nonresident member with $50,000 of California-source income who refused to sign Form 3832, the LLC withholds 6,150 and lists it on Line 4. Attach Form 3832 listing every consenting member.
The mistake is failing to obtain Form 3832 signatures before filing, which forces the LLC to pay tax on the member’s behalf. The misconception is that consent is automatic; it is not, every nonresident member must sign annually.
Line 7 — Amount Paid with Form 3537
Line 7 reports any extension payment made with FTB 3537, the Payment for Automatic Extension for LLCs. California grants an automatic 7-month extension to file, but not to pay, so any expected balance is paid with Form 3537 by the original due date.
For example, Pacific Coast Builders LLC paid $4,500 with Form 3537 in March 2026; that amount goes on Line 7. The mistake is double-counting the $800 here when it was already paid via Form 3522. The misconception is that filing an extension also extends the fee due date — it does not.
Line 8 — Amount Paid with Form 3522
Line 8 records the $800 annual tax already paid for 2025 via FTB 3522. For a calendar-year LLC, the 2025 payment was due April 15, 2025.
Enter 800 if you paid on time. If you skipped the payment, enter 0 and expect a late-payment penalty plus interest. The misconception is that a late payment somehow rolls into Form 568 — it does not, and the FTB issues a separate notice for the unpaid $800.
Line 9 — Amount Paid with Form 3536
Line 9 records the estimated LLC fee paid with FTB 3536, due the 15th day of the 6th month of the tax year. The estimated fee must equal at least the prior-year actual fee to avoid the 10% underestimation penalty.
For example, if last year’s fee was $2,500, Pacific Coast Builders LLC paid at least $2,500 with Form 3536 by June 15, 2025, even if 2025’s actual fee turned out higher. The mistake is paying the estimated fee using the current year’s projection, which is fine only if it equals or exceeds last year’s actual.
Schedule IW — Limited Liability Company Income Worksheet
Schedule IW lives on page 7 and is where Total California Income on Line 1 comes from. It walks through gross receipts, gross rents, gross royalties, gain on disposition, distributive share from other pass-throughs, and other California-source income.
For example, Pacific Coast Builders LLC enters $1,250,000 on Line 1a (California-source gross receipts) and $0 on the rest, summing to $1,250,000 on Line 17. The mistake is netting expenses against gross receipts; Schedule IW is gross, not net, and using net numbers understates the LLC fee bracket. The misconception is that Schedule IW mirrors federal gross income — it does not, because California source rules differ.
Schedule B — Income and Deductions
Schedule B on Side 4 mirrors federal Form 1065 page 1, with California adjustments. It reports gross receipts, cost of goods sold, gross profit, ordinary income, salaries, rents, taxes, and depreciation.
Start with the federal numbers and adjust for California differences such as bonus depreciation (California does not conform), federal tax credits flowed through, and any federal disaster loss deductions. The mistake is copying federal numbers without adjustments, which understates California income. The misconception is that Schedule B matches federal Form 1065 exactly — it rarely does.
Schedule K — Members’ Shares of Income, Deductions, Credits
Schedule K aggregates each member’s distributive share of ordinary income, rental income, interest, dividends, capital gains, §1231 gains, charitable contributions, and credits. Each line on Schedule K corresponds to a line on each member’s Schedule K-1 (568).
For example, if Pacific Coast Builders LLC has $400,000 of ordinary business income, Schedule K Line 1 shows 400,000 and each member’s K-1 shows their share. The mistake is mismatching Schedule K total with the sum of K-1s; the FTB’s matching system catches this within weeks. The misconception is that Schedule K is optional for SMLLCs — it is, since SMLLCs skip Schedule K and K-1.
Schedule K-1 (568) — Member’s Share
Each member receives a Schedule K-1 (568) showing their name, address, SSN/ITIN/FEIN, ownership percentage, capital account, and distributive shares. Distribute K-1s to members by the return due date, including extensions.
For example, David Chen, a 50% member of Pacific Coast Builders LLC, receives a K-1 showing 200,000 on Line 1 (ordinary income) and his ending capital account. The mistake is forgetting to issue K-1s, which exposes the LLC to a per-member penalty under §19172. The misconception is that nonresident members do not need a K-1 — they do, and they need it to file Form 540NR.
Schedule R — Apportionment and Allocation of Income
Schedule R applies if the LLC does business inside and outside California. California uses single-sales-factor apportionment for most LLCs, meaning California sales divided by total sales sets the percentage of business income apportioned to California.
For example, an LLC with $4,000,000 of total sales and $1,000,000 of California sales has a 25% sales factor, and 25% of business income is California-source. The mistake is forgetting to file Schedule R, which leaves the FTB to assume 100% California sourcing. The misconception is that service businesses use cost-of-performance — most do not, California uses market-based sourcing under R&TC §25136.
Single Member LLC Information and Consent (Side 7)
This section appears only on SMLLC returns. The single member signs a consent agreeing to California’s jurisdiction to tax, and provides the member’s name, SSN or FEIN, and ownership percentage.
For example, Maria Lopez signs as the sole member of Lopez Coastal Marketing LLC and writes 100%. The mistake is leaving this section blank on an SMLLC return, which the FTB treats as an incomplete filing. The misconception is that SMLLCs do not need to consent — they do, every year.
Signature Block
The Signature block is on Side 1 at the bottom. A managing member or authorized member signs, dates, and lists their title. A paid preparer signs in the preparer block to the right with their PTIN.
For example, Maria Lopez signs, dates 03/10/2026, and writes MEMBER as her title. The mistake is e-filing without the Form 8453-LLC e-file authorization on file, which voids the signature. The misconception is that an unsigned Form 568 still counts as filed — it does not, and the FTB treats it as a non-filing, restarting the late penalty clock.

How to File the Completed Form
California offers three filing channels, and each has its own quirks. Choose based on speed, cost, and recordkeeping needs.
E-file through approved software. Most LLCs file electronically through TurboTax Business, Lacerte, ProSeries, Drake, or another vendor on the FTB-approved list. There is no FTB filing fee for e-filing itself, payment is made via direct debit or Web Pay, processing time runs 2 to 4 weeks, and the proof of filing is the FTB acknowledgment number.
Paper file by mail. Mail Form 568 with a check or money order to Franchise Tax Board, PO Box 942857, Sacramento CA 94257-0501 if a payment is enclosed, or PO Box 942857, Sacramento CA 94257-0500 if no payment is due. Use certified mail with return receipt to lock in proof of mailing. Processing time runs 8 to 12 weeks, and California accepts checks payable to Franchise Tax Board with the FEIN, 2025 Form 568, and SOS file number written on the memo line.
Web Pay for the $800 and the LLC fee. Use FTB Web Pay for the $800 (Form 3522), the estimated fee (Form 3536), and the extension payment (Form 3537). Web Pay is free, posts within 1 to 2 business days, and confirms with a printable receipt.
The IRS has an e-file mandate for California business returns prepared by paid preparers filing more than 100 returns, so most professionally prepared 568s go electronic. Always save the acknowledgment number, the canceled check or Web Pay confirmation, and a PDF of the filed return for at least four years.
What Happens After You File
Once Form 568 hits the FTB, the system runs automated checks against the SOS database, the IRS data exchange, and California withholding records. E-filed returns usually post within 2 to 4 weeks; paper returns take 8 to 12 weeks during peak season.
If everything matches, no notice arrives. If something is off — a wrong SOS number, an unpaid fee, a mismatched K-1 — the FTB sends a Notice of Tax Return Change or an FTB 4734D demand letter. Respond within 30 days using MyFTB or by mail; ignoring a notice escalates to a Notice of Proposed Assessment.
If a refund is due, the FTB issues it within 6 to 8 weeks of acceptance for e-file or 12 to 16 weeks for paper. Members do not get K-1 information from the FTB; the LLC must distribute K-1s directly to each member by the original or extended due date so members can file their own Form 540 or 540NR. Keep the filed Form 568 and supporting workpapers for at least four years, since California’s standard audit window is four years from the original due date.
Mistakes to Avoid When Filling Out the Form
Form 568 generates more FTB notices than almost any other California return. Here are the most common errors and exactly what each one costs.
- Skipping the $800 via Form 3522. Triggers a late-payment penalty plus interest under §19132.
- Missing the SOS file number. Forces the return into manual review and delays processing by 4 to 8 weeks.
- Using federal gross income for the LLC fee bracket. Either underpays and triggers the 10% fee penalty or overpays and ties up cash.
- Filing a final-year return without checking the Final Return box. Keeps the LLC active and bills another $800 next year.
- Forgetting Form 3832 nonresident consents. Forces the LLC to pay nonresident tax on Line 4.
- Mismatching Schedule K total to the sum of K-1s. Generates an automated discrepancy notice within weeks.
- Filing without the SMLLC consent signature on Side 7. Treated as an incomplete return.
- Using last year’s PDF instead of the 2025 form. Causes line numbers to misalign and the return to be rejected.
- Confusing the $800 annual tax with the LLC fee. Leads to underpayment of one or both and stacking penalties.
- Forgetting to file Schedule R when doing business outside California. Defaults to 100% California sourcing and overstates tax.
- Late or missing K-1s to members. Triggers a per-member penalty under §19172.
- Entering the EIN in the SOS box. Guarantees rejection of the return.
Do’s and Don’ts
These quick rules keep most filers out of trouble.
Do’s:
- Do download the form fresh each year from ftb.ca.gov so line numbers match.
- Do pay the $800 with Form 3522 by the 15th day of the 4th month, because the annual tax is not paid through Form 568.
- Do file Schedule R if you do business outside California, because single-sales-factor apportionment can dramatically reduce your tax.
- Do issue K-1s by the due date including extensions, because members need them for their own returns.
- Do save proof of mailing or e-file acknowledgment, because the burden of proof of filing falls on you.
- Do reconcile Schedule IW to bank deposits before signing, because gross receipts drive the LLC fee bracket.
- Do check the Initial Return box on a brand-new LLC’s first 568, because skipping it complicates future-year matching.
Don’ts:
- Don’t use federal Form 1065 numbers as a shortcut, because California adjustments are required and the FTB checks.
- Don’t assume a dormant LLC owes nothing, because the $800 is owed even with zero income or activity.
- Don’t enter the FEIN where the SOS number belongs, because the systems treat them as two different identifiers.
- Don’t sign without verifying the LLC fee bracket, because being one dollar over a tier can cost thousands.
- Don’t ignore an FTB notice, because the next step is a Notice of Proposed Assessment with full collection rights.
- Don’t forget Form 3832 for nonresident members, because withholding stacks fast.
- Don’t paper file at the last minute, because postmark issues are routinely contested by the FTB.
Pros and Cons of Filing on Your Own vs. With Help
Filing Form 568 yourself is doable but uneven. Multi-member returns and apportionment add real complexity that often justifies a CPA.
Pros of filing yourself:

FAQs
Who must file Form 568?
Yes — every California LLC classified as a partnership or disregarded entity that is registered with the SOS, organized in California, or doing business in California must file Form 568 each year.
Do single-member LLCs file Form 568?
Yes — SMLLCs file Form 568 to report the $800 annual tax and the LLC fee, even though they are disregarded for federal income tax purposes.
Is the $800 annual tax paid through Form 568?
No — the $800 is paid separately with Form 3522 by the 15th day of the 4th month, and Form 568 only records that obligation on Line 3.
What is the deadline to file Form 568?
Yes — calendar-year LLCs file by the 15th day of the 3rd month (March 15) for partnership-classified LLCs, or the 15th day of the 4th month for SMLLCs.
Can I get an extension to file Form 568?
Yes — California grants an automatic 7-month extension to file, but not to pay; any expected tax must be paid with Form 3537 by the original due date.
What if I formed my LLC late in the year?
Yes — you still file Form 568 for the short year, owe the $800, and check the Initial Return box, because the first-year exemption sunset on January 1, 2024.
Do I write my legal name or trade name in the LLC Name box?
No — never write the trade name; write the exact legal name as filed with the California Secretary of State, in all capital letters.
What goes in the SOS file number box if I cannot find it?
Yes — look it up on the SOS BizFile portal by LLC name; never substitute the FEIN, because the FTB rejects mismatched identifiers.
Do I list every member on Schedule K-1 or only managing members?
Yes — every member with any ownership percentage during the year gets a K-1, including members who joined or left mid-year.
Should I use federal gross income for the Line 1 fee bracket?
No — only California-source income from Schedule IW counts; using federal gross income often pushes filers into the wrong bracket.
What happens if I forget to check the Final Return box?
No — the LLC stays on FTB’s active rolls and you owe another $800 the next year, even if the LLC was cancelled with the SOS.
Can I e-file Form 568 directly through ftb.ca.gov?
No — the FTB does not accept direct e-filing of Form 568 from its website; you must use approved software or paper file.
Do nonresident members owe California tax?
Yes — nonresident members owe California tax on their distributive share of California-source income; consenting members sign Form 3832, others trigger withholding on Line 4.
Is the LLC fee deductible on the federal return?
Yes — the LLC fee is generally deductible as a business expense on Form 1065 or Schedule C, but not the $800 minimum tax in many cases.
