Doing business in California means dealing with more taxes than most states. Between state taxes, local taxes, and various fees, it gets complicated fast. This guide covers the main tax considerations for California businesses, from choosing the right entity to staying compliant with state and local requirements.

Entity Selection

Choosing the right business entity affects your liability, taxes, and paperwork. It's one of the most important decisions you'll make. Many service professionals start as sole proprietors and later realize they're personally liable if something goes wrong. Picking the right structure from the start helps protect you.

Entity TypeKey Characteristics & Tax Implications
Sole Proprietorship

Default Status: No formal action required to form.

Taxation: Profits and losses are passed through to the owner's personal tax return (Schedule C).

Liability: No legal separation between the owner and the business, resulting in unlimited personal liability.

Limited Liability Company (LLC)

Liability & Flexibility: Offers the liability protection of a corporation with superior tax flexibility.

Taxation: Can be treated as a disregarded entity, a partnership, or elect to be taxed as an S or C Corporation. This is the most common and flexible structure for most businesses.

S Corporation (S Corp)

Tax Efficiency: An S Corp is a tax election that can yield significant savings on self-employment taxes for profitable businesses.

Compliance: Requires more formal operations, including paying yourself a reasonable salary. Many businesses switch to S Corp status once they're profitable enough to benefit from the tax savings.

C Corporation (C Corp)

Capital & Liability: The most robust legal structure, ideal for businesses intending to raise venture capital or retain significant earnings for reinvestment.

Taxation: Taxed as a separate entity at the corporate level, which can lead to double taxation if profits are distributed as dividends.

The Annual Minimum Franchise Tax

Almost every business entity in California owes an $800 annual minimum franchise tax. It doesn't matter if you made any money or not. You owe it just for being registered in California. This catches a lot of new business owners by surprise.

  • LLCs: The $800 tax is due by the 15th day of the 4th month following formation.
  • New Corporations: The tax is waived for the first year of operation but applies annually thereafter.

The California LLC Fee

On top of the annual franchise tax, LLCs pay a fee based on California gross receipts. Here's the important part: it's based on revenue, not profit. If you have high revenue but thin margins, this fee can be surprisingly expensive.

Total California Gross Receipts2026 Annual LLC Fee
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

You need to estimate and pay this fee by the 15th day of the 6th month of your tax year.

Local & City Business Taxes

State taxes are just part of the picture. California cities and counties add their own business taxes. Each city has different rates and rules, which makes it complicated if you operate in multiple locations.

  • City of Los Angeles: Imposes a gross receipts tax that varies by business classification. For professional services, the rate is $4.25 per $1,000 of gross receipts.
  • Culver City: The rate for professional services is $3.00 per $1,000 of gross receipts, with a full exemption on the first $200,000 of annual revenue.

Payroll & Employment Tax Compliance

Hiring employees in California comes with a lot of administrative work and tax responsibilities. As an employer, you're responsible for withholding and paying taxes to both state and federal agencies.

California Payroll Tax Obligations

Because of the complexity and potential penalties, using a professional payroll service is usually worth it. Arc & Ledger provides payroll processing services starting at $350 per quarter for businesses not on a retainer package.

Tax Credits & Deductions

California offers several tax credits that can reduce your tax bill.

  • Research & Development (R&D) Credit: Businesses doing qualified research can claim this credit. It's not just for tech companies. Manufacturing and other businesses that improve their processes may qualify.
  • New Employment Credit (NEC): You can get a credit for hiring qualified workers in certain areas. The credit is based on a percentage of their wages.
