The California Sales Tax Calculator, by city
California has the highest statewide sales tax rate in the United States at 7.25% (6% state plus 1.25% mandatory local). Cities and counties layer on district taxes from 0.10% to 3.25%, so the combined rate you actually pay runs from 7.25% in unincorporated rural areas to as much as 10.75% in pockets of Alameda and Los Angeles counties.
California also uses destination-based sourcing for most transactions: the rate is set by the buyer's address, not the seller's. A laptop shipped from a San Jose warehouse to a buyer in Los Angeles pays L.A.'s 9.50%, not San Jose's 9.375%.
What is the California sales tax rate?
The headline statewide rate is 7.25%, which is also the floor. That 7.25% breaks down into 6% true state sales tax plus 1.25% in mandatory local components (1.00% Bradley-Burns local plus 0.25% county transportation). On top of the floor, cities and counties impose district taxes through voter-approved measures — usually 0.25% increments for transportation, schools, libraries, or general fund.
California's 7.25% statewide rate is the highest state-level sales tax in the country. Indiana, Mississippi, Rhode Island, and Tennessee tie for second at 7.00%. State rates do not include local add-ons — counted together, Louisiana and Tennessee average higher.
The California sales tax formula
Two layers, one multiplication.
Base = 7.25% (6% state + 1.25% local)Combined = Base + DistrictTax = Price × CombinedPre-tax = Total / (1 + Combined)Worked example. A $500 stroller bought in the city of Los Angeles (9.50% combined): tax = $500 × 0.095 = $47.50; final price = $547.50. The same stroller in unincorporated Mono County (7.25%) costs $536.25 — an $11.25 difference from district stacking.
California sales tax by city
District rates are voter-approved at the city or county level. The CDTFA publishes a current rate file every quarter; major cities cluster between 7.75% and 10.25%, with a few outliers.
- Long Beach / Oakland / Berkeley = 10.25% (max in Alameda + parts of LA County)
- Los Angeles (city) = 9.50%
- San Jose = 9.375%
- Sacramento = 8.75%
- San Francisco = 8.625%
- Fresno = 8.35%
- San Diego = 7.75%
- Anaheim = 7.75%
- Unincorporated rural counties = 7.25% (floor)
California sales tax exemptions
Most groceries are exempt. The Revenue and Taxation Code carves out unprepared food for home consumption — produce, dairy, meat, bread, packaged cold food. About 20% of grocery spending in the average California household qualifies as taxable because of prepared, hot, or candy/soda exclusions.
Prescription drugs are exempt, as are most durable medical devices: prosthetics, hearing aids, wheelchairs, oxygen equipment, and insulin (the only non-prescription drug exemption). Over-the-counter medicines and dietary supplements are taxable.
The exemption is for unprepared food bought for home use. Rotisserie chicken, hot soup, salad bars, candy, soda, and energy drinks are all taxable. Cold sandwiches sold for off-premises consumption are exempt; the same sandwich heated up or eaten at the store becomes taxable.
California use tax and online purchases
If a retailer ships into California and does not collect sales tax, the buyer owes use tax at the same combined rate as their local sales tax. Since the Supreme Court's 2018 Wayfair decision and California's implementing legislation (AB 147), out-of-state sellers with $500,000 in California sales must register and collect.
That has mostly closed the gap for big retailers. Individual buyers still owe use tax on smaller transactions where no tax was collected; the FTB lets you report it on the state income tax return using a lookup table that estimates use tax owed by adjusted gross income.
California sales tax vs other states
California's 7.25% statewide rate is the highest in the country at the state level. With local add-ons the combined rate can reach 10.25-10.75% — high, but not the absolute peak. Tennessee, Louisiana, and Arkansas have higher average combined rates because their state rates (7%, 4.45%, 6.5%) get topped off by aggressive local sales taxes that often top 5%.
What makes California distinctive is the floor. Even the cheapest rural ZIP code pays 7.25%; in most states the floor matches the state rate (4-6%). California also taxes a relatively narrow base — services are largely exempt, food is exempt, prescription drugs are exempt — so the high rate is applied to a smaller slice of consumption than in states with broader bases. The Tax Foundation regularly ranks California's sales tax structure as the highest by statewide rate and middle-of-the-pack by total burden.
If you live near a county line and the rates differ, the practical savings on a single big-ticket purchase (a car, a high-end appliance) can run into hundreds of dollars. California taxes vehicles based on the registration address, not the dealer, so the savings only apply at non-vehicle retail.
Common California sales tax mistakes
The biggest mistake is assuming 7.25% applies everywhere. It does not. Of California's population, well over 90% lives in a district that adds at least 0.25% on top, and most major cities are at 9-10%. For budget planning, always look up the buyer's ZIP code at the CDTFA rate-lookup tool, which returns the address-specific combined rate.
The second is treating all groceries as exempt. Hot prepared food, candy (legally defined as sugar-based confection without flour), soft drinks, and dietary supplements all carry the full combined rate. The exempt portion of a typical grocery basket is closer to 80% by dollar value, not 100%. Cold sandwiches sold for take-out are exempt unless heated; the same sandwich consumed in a store seating area becomes taxable.
The third is ignoring use tax. If you buy a $2,000 item from a small out-of-state seller that does not collect California sales tax, you owe the same 9-10% to the FTB. Audit risk is highest on big-ticket items the state can match against shipping records — vehicles, boats, and furniture top the list.
A fourth and less obvious mistake is the resale-certificate trap. If a business buys inventory for resale, a properly completed resale certificate exempts the purchase from sales tax. Using a resale certificate to buy items for personal use is fraud and triggers penalties of up to 25% plus interest. Auditors regularly cross-reference resale purchases against the sales tax actually collected and remitted by the buyer.
