California Sales Tax Rates by City and County: How to Look Up the Right Rate

To look up a California sales tax rate, start with the exact transaction location rather than relying only on a city name or ZIP code. Use the California Department of Tax and Fee Administration (CDTFA) address lookup, confirm that the map point matches the intended location, and then review the resulting total rate. If you use the city-and-county table instead, make sure you distinguish an incorporated city from an unincorporated community.

California’s statewide sales and use tax rate is 7.25%, but the total rate is higher wherever district taxes apply. Because boundaries and rates can change, a saved rate, a neighboring business’s rate, or a general ZIP-code result may not be reliable for a particular transaction.

How California sales tax rates are structured

CDTFA administers California sales and use tax and provides the official rate-lookup tools. The total rate for a location begins with the 7.25% statewide rate and may include one or more district taxes.

Individual district tax rates range from 0.10% to 2.00%, and more than one district tax can apply in the same area. This is why two locations that appear to be in the same general market can have different total rates. For a closer explanation of this rate structure, see California District Sales Tax: Why Your Rate Is Higher Than 7.25%.

The rate is not merely an amount collected for CDTFA. A seller owes the sales tax and is responsible for paying the correct amount to CDTFA. The seller is responsible for the statewide rate and applicable district taxes in cities and counties where the seller is engaged in business. That makes accurate rate selection an important part of pricing, checkout configuration, recordkeeping, and return preparation.

Choose the right lookup method

CDTFA offers official rate information through an address-based lookup and a city-and-county rate table. The appropriate method depends on what information you have and how precisely you need to identify the location.

Use the address lookup for a specific location

For a transaction-specific location, enter the complete address in CDTFA’s address lookup. After the tool locates the address, inspect the matched map point rather than accepting the first displayed result without review. The map marker should correspond to the intended store, delivery destination, job site, or other location you are evaluating.

An address lookup is preferable when local boundaries may be important. A mailing city or commonly used community name does not necessarily establish that an address is inside an incorporated city. Likewise, a ZIP code can cover more than one local tax area. The matched address and map point provide a more precise basis for identifying the displayed rate.

Use the city-and-county table for general reference

CDTFA’s current city-and-county table lists rates effective July 1, 2026. It can be useful when comparing listed incorporated cities or checking listed county areas. A convenient companion reference is the California State, County, City, & Municipal Tax Rate Table.

Do not assume that every place name will appear in the city portion of the table. Unincorporated cities and communities are not listed there. If the location is outside an incorporated city, the applicable county unincorporated-area rate or county rate applies. If a community name is missing, look for the applicable county entry and use the address lookup to confirm the location.

Step-by-step rate lookup process

1. Identify the transaction you are checking. Record the complete location information available for that transaction. Do not select a rate merely from the seller’s business address, customer’s mailing city, or delivery location without first determining which location is relevant to the transaction.
2. Use CDTFA’s address lookup. Enter the street address, city, state, and ZIP code as accurately as possible. Avoid substituting a nearby landmark or central city address for the actual location.
3. Verify the mapped point. Check that the displayed point corresponds to the intended address. If it appears on the wrong street, outside the expected parcel, or in a neighboring jurisdiction, correct the address and search again.
4. Review the total rate. Treat the result as a combined rate that includes the 7.25% statewide rate plus any district taxes applicable to the location shown by the tool.
5. Cross-check the jurisdiction when necessary. If the result is unexpected, compare the location with the current city-and-county table. Pay particular attention to whether the address is inside an incorporated city or in an unincorporated county area.
6. Document the lookup. Keep the address entered, the result used, and the date checked with the transaction or tax records. This helps explain how the rate was selected if local boundaries or rates later change.
7. Recheck rates instead of treating them as permanent. Rates and jurisdiction boundaries can change. Review the current CDTFA information before using an old result for a later transaction.

The correct district-tax sourcing treatment can depend on the seller’s activities and the circumstances of delivery. A rate lookup identifies the rate associated with the location entered, but selecting the legally relevant location may require attention to the facts of the transaction. Avoid creating a blanket rule for every sale if your business uses several fulfillment, pickup, installation, or delivery arrangements.

Practical mistakes to avoid

• Using 7.25% for every California sale. That is the statewide rate, not necessarily the total rate. District taxes can increase the amount applicable in a particular area.
• Searching only by ZIP code. A ZIP code is designed for mail routing and should not be treated as conclusive proof of a local tax boundary. Use the complete address and verify the map point.
• Assuming a community is an incorporated city. An unincorporated community may have a familiar place name even though it is outside city boundaries. Use the county unincorporated-area or county listing when appropriate.
• Choosing the nearest city in the table. Geographic proximity does not establish that two locations share a rate. Look up the actual address rather than borrowing a nearby city’s result.
• Ignoring multiple district taxes. More than one district tax may apply in an area. Do not try to reconstruct the total from memory when a current official lookup is available.
• Saving one result indefinitely. A rate used for an earlier transaction may not remain current. Recheck the official information when processing transactions after a rate change or when the relevant location differs.
• Confusing rate lookup with registration. Finding a rate does not replace obtaining a seller’s permit when one is required. Registration establishes the business’s account; rate lookup helps determine the rate associated with a location.

Registration and next steps

A person selling or leasing tangible personal property in California, even temporarily, is generally required to register with CDTFA and obtain a seller’s permit unless a specific exemption or exclusion applies. This requirement covers online and other selling methods.

Applicants may register through CDTFA Online Services by selecting “Register a New Business Activity,” or they may register in person at a CDTFA office. There is no charge for a seller’s permit, although CDTFA may require a security deposit depending on the type of business and its expected taxable sales. Businesses preparing to register can review the California CDTFA Sales Tax Registration Process for New Businesses in 2026.

After registration, build rate verification into the sales workflow. Decide who is responsible for checking new addresses, how lookup results will be recorded, and when saved rates will be reviewed. Businesses selling from or into several California locations should also separate the task of identifying the applicable transaction location from the task of looking up the rate for that location. This reduces the risk of applying an accurate rate to the wrong jurisdiction.

For an immediate lookup, gather the full address, confirm whether it is in an incorporated city or an unincorporated county area, verify the map point, and record the current result. If the applicable location is uncertain because of the seller’s activities or delivery arrangement, resolve that sourcing question before assigning the rate.
