Choosing California as a business location is also a tax decision. For a startup, that decision can begin before the first employee is hired or the first sale is made.
The tax consequences depend on more than where a company is incorporated. Entity type, California income, employees, property, sales and the extent of business activity can all affect what a company must file and pay.
That makes California business taxes less about finding one headline rate and more about understanding how several tax systems interact.
A California C corporation, S corporation, LLC and sole proprietorship can face very different obligations. An out-of-state company can also become subject to California requirements without formally incorporating in the state.
For founders and established companies, the useful question is therefore not simply how much tax California charges. It is what tax and compliance structure the company’s planned operations will create.
The California Tax Structure at a Glance
California’s business tax system includes several separate components.
The Franchise Tax Board (FTB) administers the state’s corporation and personal income taxes, including taxes applying to many businesses. The California Department of Tax and Fee Administration (CDTFA) handles sales and use taxes. Employers also have payroll-tax responsibilities through the Employment Development Department (EDD).
For corporations, California generally imposes an income or franchise tax based on the company’s taxable income, with an $800 minimum franchise tax for corporations subject to it. LLCs have a separate $800 annual tax and may also owe an additional fee based on California income.
Sales tax is different. It generally applies to taxable sales of tangible personal property rather than simply to a company’s existence in California.
The result is a layered system rather than a single business tax.
How Business Structure Changes the Tax Picture
The entity chosen by a founder can materially change the California tax calculation.
| Business structure | Main California tax consideration | What to examine |
|---|---|---|
| LLC | $800 annual tax plus possible LLC fee | California income and tax classification |
| C corporation | 8.84% corporate tax for most corporations plus applicable minimum franchise tax | Taxable income and California activity |
| S corporation | 1.5% California tax plus applicable $800 minimum franchise tax | Shareholder structure, income and apportionment |
| Sole proprietorship | Business income generally reported through the owner’s individual tax return | California-source income and individual tax position |
A C corporation generally pays California tax at 8.84%. Newly incorporated or qualified corporations are generally not subject to the $800 minimum franchise tax in their first taxable year, although first-year net income can still be taxed.
S corporations are generally subject to a 1.5% California tax. California also applies an $800 minimum franchise tax, although the minimum is waived for a newly formed or qualified S corporation’s first taxable year under the conditions described by the FTB.
An LLC is different because its federal tax classification can vary. An LLC may be treated as a disregarded entity, partnership or corporation for tax purposes, depending on its ownership and elections.
That means the legal entity name alone does not tell the complete tax story.
The $800 Question for LLCs and Corporations
The $800 figure is frequently misunderstood.
For 2026, an LLC generally owes an $800 annual tax if it is doing business in California or has articles of organization or a certificate of registration issued by the California Secretary of State. The tax is separate from the additional LLC fee that may apply at higher income levels.
For LLCs with California annual income of at least $250,000, the additional fee is currently:
- $250,000–$499,999: $900
- $500,000–$999,999: $2,500
- $1 million–$4.999 million: $6,000
- $5 million or more: $11,790
These amounts are based on the LLC’s California income under the FTB’s rules, not simply its net profit.
Corporations have a different structure. The $800 minimum franchise tax generally applies to corporations incorporated, registered or doing business in California, while the measured tax is based on income under California rules.
For a startup, these recurring obligations matter because they can arise even when the company is still developing its revenue model.
Sales and Use Tax: When Does It Apply?
Sales and use tax is a separate issue from corporate or franchise income tax.
California’s statewide sales tax rate is currently 7.25%, but local district taxes can increase the rate depending on the location of the transaction. California’s current district rates can add between 0.10% and 2.00% in applicable areas.
A company generally needs a California seller’s permit when it is engaged in business in the state and sells or leases tangible personal property that would ordinarily be subject to sales tax.
The requirement applies to corporations, LLCs, partnerships and other business structures.
Use tax can also become relevant when taxable merchandise is purchased for use, storage or consumption in California and sales tax was not collected.
For companies selling physical products, the practical issue is therefore not simply the tax rate. Businesses must determine which transactions are taxable, where tax is due, what registrations are required and how returns and payments will be handled.
What Happens When an Out-of-State Company Enters California?
California tax exposure does not necessarily begin with forming a California corporation.
The FTB considers a business to be doing business in California under several circumstances, including engaging in transactions for financial gain in the state, being organized or commercially domiciled there, or exceeding specified California sales, property or payroll thresholds.
For 2025, the FTB lists thresholds of $757,070 for California sales and $75,707 for California property or payroll, with the alternative 25% tests also applying. These thresholds are updated over time, so companies expanding into California should use the figures applicable to the relevant tax year.
Importantly, falling below those thresholds does not automatically mean a company is outside California’s tax system. The FTB notes that a company can still be considered to be doing business in California if it actively engages in a transaction in the state for financial gain or profit.
Employees can also matter. The FTB gives the example of an out-of-state partnership whose California-based employees sell and provide warranty services to California customers. Even when property, payroll and sales remain below the listed thresholds, the employees’ activities can result in the business being considered to be doing business in California.
This is particularly relevant for companies using remote employees or expanding across state lines.
The Costs Beyond the Headline Tax Rate
The actual cost of establishing a California operation can extend beyond income and sales taxes.
Companies with employees can have payroll-tax obligations through the EDD. California’s four state payroll taxes include Unemployment Insurance and Employment Training Tax, which are employer-paid, plus State Disability Insurance and Personal Income Tax withholding from employee wages.
For 2026, California’s EDD lists a 0.1% Employment Training Tax rate and a 1.3% State Disability Insurance withholding rate. UI rates vary by employer circumstances, with a 3.4% rate applying to new employers for the applicable period.
An employer generally must register with the EDD within 15 days after becoming an employer that hires employees and pays more than $100 in wages in a calendar quarter.
There are also business-registration and filing obligations. California’s Secretary of State requires qualifying entities to file Statements of Information, and failure to meet required filing obligations can lead to penalties or suspension or forfeiture.
These administrative requirements do not always appear in a headline tax-rate comparison, but they affect the cost of maintaining a California operation.
The Real California Tax Decision
For founders, the more useful calculation is the total annual tax and compliance cost relative to revenue, margins, workforce, physical footprint and growth strategy.
A software startup with a small California team can have a very different tax profile from a manufacturer operating a warehouse and employing hundreds of workers. A company selling physical products can have sales-tax obligations that a services business may not face in the same way.
An out-of-state company can also create California obligations through employees, sales or other business activity without establishing a traditional headquarters there.
This is why entity selection and operating structure should be considered together.
The decision is not simply whether to form an LLC or corporation. It involves examining how the entity will earn revenue, where employees will work, where property will be located, whether products are taxable, how income will be apportioned and which registrations will be triggered.
Conclusion
California business taxes are best understood as a combination of entity-level taxes, income rules, sales and use taxes, payroll obligations and compliance requirements.
For 2026, the headline figures include an 8.84% tax rate for most C corporations, a 1.5% California tax for S corporations, an $800 annual LLC tax and an additional LLC fee beginning at $900 once California income reaches $250,000. Sales-tax obligations are separate and depend on taxable transactions and applicable local rates.
But none of these numbers should be viewed in isolation.
Before establishing a California presence, a company should model its expected revenue, workforce, property, sales, entity structure and recurring compliance requirements. That approach provides a more useful picture of the economics than relying on a single tax rate.
