What Is the Sales Tax in California?

The base sales tax rate in California is 7.25% (march 2026), but the total rate varies by location due to local taxes.

You can verify current California sales tax rates in the official California sales tax rate table published by the California Department of Tax and Fee Administration at https://cdtfa.ca.gov/taxes-and-fees/TaxRatesbyCountyandCity.pdf.

In most areas, the combined rate ranges from 7.75% to over 10%.

Why Sales Tax Varies in California

In California, sales tax can include additional local taxes imposed by cities, counties, and special districts.

These district taxes are usually approved by voters and are used to fund infrastructure, transportation, and public services.

Because of this, the total sales tax rate can vary even within the same region.

Example Calculation

Example (rates valid as of March 2026):

If you buy an item for $100 and your local tax rate is 9.5%:

• Tax = $9.50
• Total = $109.50

This rate typically includes the base state tax along with additional taxes from cities, counties, and special districts.

To calculate sales tax manually, multiply the price by the tax rate and add it to the total.

Sales and Use Tax in California

In California, sales tax and use tax are closely related.

Sales tax is collected by the seller at the time of purchase, while use tax applies when sales tax was not collected.

This commonly happens with online or out-of-state purchases.

Use tax is generally calculated using the same rate as sales tax and is reported through the same system.

Sales Tax Forms in California

Businesses in California must file sales and use tax returns using forms provided by the California Department of Tax and Fee Administration.

The most commonly used form is the CDTFA-401-A (Sales and Use Tax Return), which is used to report and pay sales and use tax.

Most businesses file electronically through the CDTFA system, but you can learn more about forms and filing requirements on the official California Department of Tax and Fee Administration website at https://www.cdtfa.ca.gov/

Forms and filing requirements may vary depending on your business type and reporting frequency.

• Annually – for low-volume sellers

Deadlines are typically due at the end of the month following the reporting period.
