California has one of the most complex and expensive business tax environments in the United States. The state imposes a corporate income tax rate of ~8.84%, an alternative minimum tax, an LLC fee based on gross receipts, an LLC annual tax, and high personal income tax rates that affect pass-through entity owners. Despite these costs, California’s massive economy, talent pool, and venture capital ecosystem continue to attract businesses across all industries.

California Business Tax Overview (2026)

Tax TypeRate / Structure
Corporate income tax (C-Corp)~8.84%
Corporate alternative minimum tax~6.65%
S Corporation tax~1.50%
LLC annual minimum tax~$800
LLC fee (gross receipts-based)~$0 to ~$11,790
Personal income tax (pass-through owners)Up to ~13.30%
Sales tax~7.25% to ~10.75%

Corporate Income Tax

California’s ~8.84% corporate franchise tax rate applies to C corporations on their California-apportioned income. Key features:

Apportionment

California uses single sales factor apportionment, meaning only the percentage of revenue from California customers determines how much income is taxed. This benefits companies with significant operations in California but customers nationwide, while penalizing companies whose customer base is concentrated in California.

Minimum Franchise Tax

All corporations doing business in California must pay a minimum franchise tax of ~$800 per year, regardless of income. This applies even to dormant or unprofitable corporations.

Alternative Minimum Tax (AMT)

California imposes a corporate AMT of ~6.65% on preference items, which can increase the tax for companies with significant AMT adjustments.

S Corporation Tax

California is one of the few states that imposes a separate tax on S corporations, at a rate of approximately ~1.50% of net income. This is in addition to the income tax paid by shareholders on their pass-through income. The minimum S Corp tax is ~$800 per year.

LLC Tax and Fee

California LLCs face a two-part tax burden:

Annual LLC Tax

All LLCs doing business in California or organized in California pay an annual minimum tax of ~$800, regardless of income or activity.

LLC Fee (Gross Receipts-Based)

In addition to the ~$800 annual tax, LLCs with California-source gross receipts above ~$250,000 pay a fee based on total California income:

Total California IncomeLLC Fee
$0 — $249,999$0
$250,000 — $499,999~$900
$500,000 — $999,999~$2,500
$1,000,000 — $4,999,999~$6,000
$5,000,000 and above~$11,790

Important: The LLC fee is based on total income (gross receipts), not profit. An LLC with $5 million in revenue but zero profit still owes ~$11,790 plus the ~$800 annual tax.

Pass-Through Entity Tax (PTET)

California offers an electable Pass-Through Entity Tax that allows qualifying entities to pay state tax at the entity level (at approximately ~9.30%) and provides a corresponding credit to owners. This is designed to work around the federal $10,000 SALT deduction limitation, effectively allowing pass-through owners to deduct California state taxes above the cap.

California’s combined business tax burden (corporate tax + LLC fees + high personal income tax) is among the highest in the nation.

Tips for Minimizing California Business Tax

  1. Evaluate entity structure carefully. The ~1.50% S Corp tax and ~8.84% C Corp tax have different implications. Pass-through entities may face lower entity-level tax but higher personal income tax on distributions.

  2. Elect the Pass-Through Entity Tax. If you are a pass-through entity owner, the PTET election at approximately ~9.30% can provide a workaround for the federal SALT deduction cap.

  3. Plan for the LLC fee threshold. If your California gross receipts are near a threshold (e.g., just above $250,000 or $5,000,000), consider timing strategies to manage the fee level.

  4. Optimize apportionment. California’s single sales factor means revenue from out-of-state customers is not taxed. Expanding your customer base beyond California can significantly reduce your California tax liability.

  5. Plan for the $800 minimum. Even dormant entities owe ~$800 per year. Dissolve entities that are no longer active to avoid ongoing minimum tax obligations.

  6. Consider the R&D credit. California offers a research and development tax credit of approximately ~24.00% (of qualified research expenses above a base amount) that can substantially offset corporate income tax.
