Frequently asked
- What is the sales tax rate in Santa Rosa?
- 10% — the California state rate of 7.25% plus 2.75% in district taxes in effect in Santa Rosa, as published by the CDTFA for rates effective July 1, 2026.

- Is the Santa Rosa rate the same for every ZIP code?
- Not necessarily. Sales tax is set by city and district boundaries, not by ZIP code, and a ZIP can cross a city line. If an address sits near a boundary, the CDTFA's address lookup at maps.cdtfa.ca.gov gives the rate for that exact address.
- Does the rate apply to everything I buy?
- No. Most groceries and prescription medicines are exempt in California, and some items carry extra fees on top. This calculator applies the general rate to a taxable amount.
