California Small Business Taxes: The Employer’s 2023 Guide

California isn’t just home to two of the world’s biggest industries—tech in Silicon Valley and show business in Los Angeles—it’s also home to millions of eager entrepreneurs. According to 2022 data from the Small Business Administration’s Office of Advocacy, small businesses make up 99.8% of all California businesses. With 4.2 million small businesses across the state, California is the state with the largest number of small businesses.  

However, California is also one of the states with the steepest business taxes. If you own a small business in California—or want to start one—it’s crucial to understand how small business taxes in California work. 

Below, we break down the different types of business taxes imposed, the tax rates, and which ones apply to which business entities. 

Which types of taxes do business owners pay in California?

In California, business owners pay different taxes according to business type. Depending on how you structure your operation, you could end up paying a California corporate tax, an alternative minimum tax (AMT), or a franchise tax. 

California corporate taxes

California corporate tax, which is the tax on an organization’s profits, applies to C corporations and Limited Liability Companies (LLCs) that elect C corp status. The corporate tax rate in California is higher than the average corporate tax rate in the US. It’s a flat 8.84%, and applies to net taxable income from any business activity in the state. 

California alternative minimum tax (AMT)

AMT is a tax imposed to ensure that a tax filer pays a certain amount in taxes—regardless of how many business tax deductions they take or tax credits they claim. The AMT in California is 6.65%. 

Corporations that don’t report a net income profit—because they take advantage of a lot of business tax deductions, for example—have to pay AMT instead of the corporate tax. The same treatment goes for LLCs that operate as C corps and don’t report a net income. 

California franchise taxes

Franchise taxes don’t apply to franchise businesses specifically. Rather, franchise taxes are taxes certain businesses have to pay for the privilege of doing business in California. In California, the franchise tax applies to C corps, S corporations, LLCs, limited partnerships (LPs), and limited liability partnerships (LLPs). 

The minimum franchise tax is $800, but the exact amount you pay depends on your business type. Here’s a breakdown:  

  • C corps: C corps have to pay the minimum franchise tax of $800. 
  • S corps: S corps have to pay a franchise tax of 1.5% of their net income or the minimum of $800, whichever is larger. 
  • LLCs: Every LLC has to pay a minimum of $800 in franchise taxes; however, the exact amount varies based on an LLC’s net income. If an LLC earns between $250,000 and $499,999, the franchise tax goes up to $900. If an LLC’s net income is between $500,000 and $999,999, they pay $2,500 in franchise taxes. For a net income between $1 million and $4,999,999, the franchise tax is $6,000. With a net income of $5 million or more, the franchise tax is $11,790. 
  • LLCs with C corp status: LLCs operating as C corps have to pay the minimum franchise tax of $800.
  • LPs and LLPs: Because they’re considered LLCs, LPs and LLPs each pay the minimum franchise tax of $800 a year. 
  • General partnerships and sole proprietorships: These business types don’t pay franchise taxes. 

California state income taxes

Sole proprietors, independent contractors, and people who earn income from pass-through entities like S corps and LLCs have to pay personal income taxes. The state income tax rate ranges from 1% to 12.3%, depending on your tax bracket and filing status. 

Below are the 2022 tax rates for people who are single or married but filing separately. You can see the rest of the 2022 tax rates for joint filers and heads of households here.
