California LLC Taxes: 7 Steps To Comply In 2026
Comprehensive guide to California LLC taxes, fees, filing deadlines, and compliance strategies for 2026 business owners.
California imposes specific tax requirements on Limited Liability Companies (LLCs) operating within the state, distinct from federal rules. These include a mandatory annual franchise tax and potential additional fees based on gross income, alongside pass-through income taxation for members.
Overview of LLC Tax Classifications in California
LLCs in California are typically treated as pass-through entities for tax purposes, meaning business income flows directly to owners’ personal tax returns rather than being taxed at the entity level. Single-member LLCs default to sole proprietorship status, while multi-member LLCs are treated as partnerships. Owners report their share of profits or losses on individual California income tax returns, facing rates up to 13.3% at the state level.
However, regardless of federal classification, all California LLCs must pay an $800 annual tax to the Franchise Tax Board (FTB), even if inactive or unprofitable. This tax applies from the year of formation until formal cancellation.
The Mandatory $800 Annual Franchise Tax
Every LLC doing business or organized in California owes an $800 annual tax. This is not an income tax but a franchise tax for the privilege of operating in the state. It is due for the first year by the 15th day of the 4th month after filing Articles of Organization with the Secretary of State (SOS). Subsequent payments are required annually thereafter.
Foreign LLCs (formed outside California but doing business here) must also pay this tax after registering with the SOS. Failure to pay triggers penalties starting at 5% of the unpaid tax plus 0.5% monthly interest.

Additional LLC Fee Based on Gross Income
Beyond the $800 tax, LLCs classified as partnerships or disregarded entities pay an extra fee if total California-sourced gross income exceeds $250,000. This fee scales with income levels:
| Total California Income | LLC Fee Amount |
|---|---|
| Less than $250,000 | $0 |
| $250,000 – $499,999 | $900 |
| $500,000 – $999,999 | $2,500 |
| $1,000,000 – $4,999,999 | $6,000 |
| $5,000,000 or more | $11,790 |
Use Form FTB 3536 for estimated fee payments if applicable. Income is calculated before deductions, and apportionment applies for multi-state operations via Schedule R.
Federal vs. California Tax Treatment
- Pass-Through Default: LLC income passes to members, reported on federal Form 1040 (Schedule C for single-member) or Form 1065 (partnerships with K-1s). California mirrors this but adds state-specific filings.
- Corporate Election: LLCs can elect C-corp (Form 100) or S-corp (Form 100S) status, subjecting them to entity-level taxes but potentially lower overall rates.
- Disregarded Entities: Single-member LLCs file as sole proprietorships but still submit Form 568 in California.
Key Filing Deadlines for 2026
California aligns many deadlines with federal ones but mandates Form 568 for most LLCs:
- Multi-Member LLCs/Partnerships/S-Corps: Form 568 due March 15, 2026.
- Single-Member LLCs: Form 568 due April 15, 2026.
- New LLCs: $800 tax due 3.75 months after SOS filing; full Form 568 by standard deadline.
- $800 Tax Payment: Use Form FTB 3522; same deadlines as above.
Extensions are automatic for six months (e.g., September 15 for partnerships, October 15 for individuals) if taxes are paid by original due date—no form required.
Quarterly Estimated Tax Payments
If your LLC anticipates owing $500+ in state income tax, members must make quarterly estimates:
- April 15, 2026
- June 15, 2026
- September 15, 2026
- January 15, 2027
Deadlines shift to the next business day if on weekends/holidays. Non-residents use Form 540NR.
Penalties for Non-Compliance
Late payments incur:
- 5% penalty on unpaid $800 tax.
- 0.5% monthly interest.
- Additional fines for late Form 568 (up to $18 per member per month).
Disaster extensions may apply in affected areas.
Special Rules for Foreign and Non-Resident Owners
Out-of-state LLCs doing business in California must register, file Form 568, and pay taxes/fees on California-sourced income. Non-resident members report via Schedule K-1 and Form 540NR. Foreign non-registered LLCs with CA income file Form 565.
Steps to Form and Maintain a California LLC
- Choose a unique name compliant with CA rules.
- Appoint a registered agent.
- File Articles of Organization (Form LLC-1) with SOS.
- Submit initial Statement of Information (Form LLC-12).
- Draft an operating agreement.
- Obtain EIN from IRS.
- Pay initial $800 tax.
Tax-Exempt Status for LLCs
LLCs seeking non-profit-like exemption file Form FTB 3500 with the FTB, providing supporting documents. Approval is not guaranteed and rare for for-profit structures.
Recent Tax Changes Impacting 2026
Key updates include restored 100% bonus depreciation, higher SALT deduction caps, and elevated Form 1099-NEC thresholds to $2,000.
