California Sales Tax Calculator

California sales tax begins with a 7.25 percent statewide base rate, but the total charged at a specific location can be higher because local and district taxes may apply. The California Department of Tax and Fee Administration (CDTFA) explains that the sales and use tax rate has three parts: the state rate, the local rate and any district rate in effect.

Because of those additional pieces, a shopper in Los Angeles, San Diego or San Jose should not assume a single statewide number is the final rate. A city or county can fall within one or more district tax areas, and the rate can change when a new district tax takes effect. A street address is often more reliable than a ZIP code alone when determining the correct rate.

This article describes California’s base rate, local and district taxes, the official address lookup and simple calculation examples. It provides general information rather than a tax determination for a particular person or business. For an invoice or filing, use CDTFA’s current rate tools and verify the item’s taxability.

California Sales Tax at a Glance

The 7.25 percent figure is the statewide base. It is not a universal combined rate. CDTFA’s city and county information shows rates that differ widely by location and notes that some communities within a county or city may not be listed separately.

CDTFA’s consumer guidance states the rate depends on where an item is bought or where it will be used. The sales and use tax in effect at the time of purchase applies.

How California Sales Tax Is Built

State rate

The statewide base is 7.25 percent. It is the starting point for a basic tax calculation, but the final customer charge can include additional layers.

Local rate

Local tax is part of the overall rate and varies by jurisdiction. County or city boundaries do not always match a mailing address or ZIP code.

District rate

District taxes are voter- or local-government-approved taxes that apply inside defined areas. CDTFA notes that a large share of California businesses are located or operate in areas with a district tax, and a location can have more than one district tax in effect.

Use tax

Use tax generally applies when taxable goods are stored, used or consumed in California in a transaction that was not subject to sales tax. CDTFA further explains that use tax can apply to goods shipped to a California consumer from another state, including purchases made by mail, phone or online.

Rate components are separate from the taxability question. First determine whether the item or service is taxable. Then identify the correct rate and location.

How to Find the Rate for an Address

Use CDTFA’s official address lookup to get a current, location-specific rate. CDTFA also provides a city and county rate page and downloadable rate files.

Steps to follow:

1. Identify the full delivery, retail or use address.
2. Open CDTFA’s Find a Sales and Use Tax Rate tool.
3. Enter the street address and review the location returned.
4. Check the statewide, local and district components.
5. Confirm the effective date or the current rate period.
6. Save the lookup result with the invoice or business record.

A ZIP code alone may not show every boundary detail. CDTFA says it is not always possible to determine the correct rate solely from a mailing address or ZIP code, and it offers address and local database resources to help retailers identify the right rate.

Unincorporated communities require extra care. CDTFA’s city and county table notes that some unincorporated cities and communities are not listed; in those cases the county or unincorporated-area rate may apply.

If a business charges tax to customers, keep a rate log with the address, rate, effective date, source link and the date checked. Update it when CDTFA publishes a new rate period.

Why City and County Rates Differ

California’s local tax structure is based on jurisdictions and districts, not on a single uniform rate for all places with the same state name. A purchase in an incorporated city can have a different combined rate from a purchase in an unincorporated county area.

The same county can contain cities with different district taxes. For example, a seller in Los Angeles County should not assume one county figure applies to every city. The city, district boundaries, delivery details and effective date can change the result.

District taxes can change over time. CDTFA’s current rate page lists rates effective October 1, 2026 and provides historical and active district-rate resources. If a seller relies on an old table, it may collect too little or too much tax.

CDTFA’s consumer guidance also explains that a buyer who purchases an item from outside California for use in the city or county where the buyer lives may owe use tax if tax was not collected. That is another reason the location where an item will be used matters.

How to Calculate California Sales Tax

For a simple taxable purchase, use this formula:

Sales tax = taxable price × combined tax rate

Convert the percentage to a decimal before multiplying. A combined rate of 9.5 percent becomes 0.095.

Example: for a taxable $200 item at a 9.5 percent combined rate:

$200 × 0.095 = $19 tax

The total paid would be:

$200 + $19 = $219

For a $100 taxable purchase at the 7.25 percent statewide base rate: $100 x 0.0725 = $7.25 tax. $100 + $7.25 = $107.25 total.

This example assumes the item is fully taxable, the 9.5 percent rate applies to the location and transaction, and no special rule changes the tax base.

If the tax is already included in the total and the correct rate is known, divide the tax-inclusive total by 1 plus the rate as a decimal. At 9.5 percent:

$219 ÷ 1.095 = $200 pre-tax amount

A reverse calculation separates a known tax-inclusive total. It does not determine which district applies or whether the item is taxable.

A rate comparison example

A $500 taxable purchase at a 7.25 percent rate produces $36.25 in tax. The same purchase at a 9.75 percent rate produces $48.75 in tax. The difference is $12.50 on the same pre-tax price.

The example is not a rate claim about a specific city. It demonstrates why the final rate should be checked for the actual address instead of assumed from the statewide base.

California Use Tax and Online Purchases

Use tax generally applies when taxable goods are purchased in a transaction where sales tax was not charged and then stored, used or consumed in California. CDTFA states this can include purchases shipped from another state and delivered to a California consumer.

For the general rule, see What Is Use Tax.

For an online purchase, keep the order confirmation, delivery address, item description, tax line and seller information. Check whether the seller or marketplace collected California tax. If tax was not collected, review current CDTFA guidance for the buyer’s situation.

A resale purchase can create another question if the buyer later uses the item rather than reselling it. A seller’s permit, resale documentation and business records should reflect the actual use of the purchase.

Businesses operating in California must register with CDTFA and pay state sales tax on taxable retail sales, subject to the rules and exemptions that apply. CDTFA provides seller-permit, filing, use-tax and tax-rate resources.

Do not treat a broad calculator result as proof of compliance. A calculator can multiply a taxable amount by a rate but does not resolve nexus, taxability, resale status, district boundaries or filing obligations.

Common Questions About California Sales Tax

What is the California sales tax rate?

The statewide base sales and use tax rate is 7.25 percent, according to CDTFA.

Is California sales tax always 7.25 percent?

No. Local and district taxes can increase the combined rate, and a location may have more than one district tax.

How do I find California sales tax by address?

Use CDTFA’s official address lookup and check the current city and county rate information. A full address is safer than relying only on a ZIP code.

Why is the rate different in Los Angeles, San Diego and San Jose?

Cities and counties can fall within different local and district tax areas. The exact rate depends on the address and effective period, so check CDTFA’s lookup for the current rate.

Does California have use tax?

Yes. Use tax can apply to taxable goods stored, used or consumed in California when sales tax was not paid, including some out-of-state or online purchases.

What rate applies in an unincorporated California area?

The county or unincorporated-area rate may apply. CDTFA notes some unincorporated communities are not listed in the city table, so use the location resources rather than guessing from the nearest city.

What happens if a rate changes after I bought an item?

CDTFA states the sales and use tax in effect at the time of purchase applies. Keep the invoice date and the rate source with the transaction record.

Can I separate tax from a California receipt total?

Yes, if the correct combined rate is known and the total includes only the tax being separated. Divide the total by 1 plus the rate as a decimal. Confirm the location and taxability first.

California sales tax is simplest to calculate when the item, address, district and effective date are all correct. Start with the 7.25 percent statewide base, check local and district additions, and keep the official source with the calculation.

California Sales Tax Rates by City

Los Angeles, San Diego, San Jose, San Francisco, and Sacramento do not share one combined rate, so start with the rate for the city where the purchase is made. Compare these rates with the sales tax rates guide, then use the reverse sales tax calculator to separate the tax from a receipt total.

Rates are combined state, local, and district rates, checked November 5, 2026 in the CDTFA’s official address lookup and CDTFA-95, California Sales and Use Tax Rates by County and City, operative October 1, 2026. Los Angeles, San Diego, and San Francisco are not listed as separate city entries in CDTFA-95, so each was checked at its city hall address in the lookup. Confirm the rate for a specific address before you calculate; for comparison, see how local rates work in Ohio.
