Filing California Sales Tax FAQs
Where do I mail my California sales tax return?
If filing a paper sales and use tax return, mail it to the California Department of Tax and Fee Administration (CDTFA) office listed on your pre-printed tax return forms. Be sure to sign the return and include proper documentation and payments if owed. And do check the exact mailing address for your CDTFA district office, as it varies by region. Alternatively, you can file conveniently online for free through the CDTFA's online filing system.
How do I claim my California sales tax refund?
If you collected and remitted excess California sales tax in a previous tax period, you must file an amended return to claim an overpaid refund amount. Complete CDTFA form CDTFA-101-X Amended Sales and Use Tax Return, entering the corrected figures and negative amount to get refunded.
Clearly explain the reason and calculation of the credit or refund requested when submitting the amended return. Alternatively, you can file form BOE-101, State of California Claim for Refund or Credit, to claim a refund. Provide all supporting documentation and details demonstrating the overpayment for review.
How do I file my CA state tax return?

The easiest and fastest way is to file electronically using approved online tax preparation services or software like TurboTax. You simply enter your income, deduction, and credit information into the interactive program.

What is the current California sales tax?
California currently has a base statewide sales tax rate of 7.25%. On top of this, many cities and counties add additional local district taxes that apply to sales made in their jurisdiction. Some areas have no local taxes, while others can be as high as 3%.
Therefore, sales tax rates range from a minimum of 7.25% to 10.5% at the highest combined state and local levels, depending on where taxable sales are sourced. Use CDTFA resources like rate lookup tools, ZIP Code maps, and address-based rates to accurately charge customers the correct sales tax.

As a taxpayer filing individually, your complete CA state tax return and any money owed must be submitted by the federal due date in April—April 15th, 2026, for 2025 returns.
