California's base sales tax rate and how it breaks down
California's statewide sales tax is 7.25%, but the rate you pay depends on where you buy. Counties and cities add their own taxes on top of the state rate, so your actual rate ranges from 7.25% to over 10% depending on your location. The state collects 6.25%, and the remaining 1% goes to counties.
When you make a purchase, the retailer charges you the combined rate for that specific address. A $100 item costs different amounts in different parts of California because of these local additions. The rate that applies is the one where the sale physically happens — not where you live or where the business is headquartered.
Local tax rates change when counties or cities vote to increase them, usually to fund schools, transportation, or public services. These changes take effect on specific dates and explore to all purchases made on or after that date. You can find your exact rate by entering your address on the California Department of Tax and Fee Administration (CDTFA) website.
Key Takeaways
- California's base rate is 7.25%, but your actual rate includes county and city additions that vary by location.
- The rate that applies is determined by the address where you make the purchase, not where you live.
- Local rates range from 7.25% in a few areas to over 10% in others, depending on how many local taxes your county and city have added.
- You can look up your exact rate on the CDTFA website by entering your zip code or address.
- Local rates change when voters approve new taxes, and these changes take effect on specific dates throughout the year.
How county and city taxes stack on top of the state rate
After the state takes its 6.25%, counties can add up to 1.25% in county sales tax. Most California counties use this option and add close to 1%. On top of that, individual cities can add their own local sales tax, usually between 0.5% and 2%, depending on what local voters have approved.
The way these stack matters for your bill. If you live in a county with a 1% county tax and a city with a 1.25% city tax, your total is 7.25% + 1% + 1.25% = 9.5%. A neighboring city in the same county might have a different city rate, so the total would be different even though you're in the same county.
Some special districts — transit agencies, school districts, or fire protection areas — can also add their own sales taxes. These are less common but do exist in certain areas. The CDTFA publishes a complete list of all active local rates by location.
Where to find your exact rate
The California Department of Tax and Fee Administration maintains a sales tax rate lookup tool on its website. You enter your street address or zip code, and it shows you the exact combined rate for that location. This is the most reliable way to know what you'll pay, because rates vary block by block in some areas.
If you're a business owner or handle sales, you need to register with the CDTFA and collect the correct rate for each location where you make sales. If you sell online and ship to California, you collect the rate for the customer's delivery address. The CDTFA provides a database that updates when rates change.
Local tax rates change several times per year as new voter-approved measures take effect. If you're planning a large purchase or budgeting for a business, check the current rate a few days before the transaction. Rates posted on retailer websites are usually current but can lag by a day or two after a change.
Why rates differ so much across California
California allows local governments to set their own sales tax rates through voter approval. This means wealthier areas and areas with strong local support for public services often have higher rates. Rural counties sometimes have lower rates because fewer voters approved local measures.
The money from local sales taxes funds specific things: schools, public transit, homeless services, parks, or road repairs. When a city or county puts a tax measure on the ballot, voters see exactly what the money will pay for. If it passes, that rate applies to all sales in that area.
This creates a patchwork where neighboring cities can have very different rates. Someone buying groceries in one city might pay 7.5% tax, while the same purchase five miles away costs 9.75% tax. Online retailers and businesses with multiple locations have to track these differences carefully.
Sales tax on groceries and other exemptions
California does not tax most groceries — fresh produce, meat, dairy, and bread are exempt from sales tax. However, prepared foods, candy, and soda are taxable. This means a raw chicken breast is tax-free, but rotisserie chicken is taxed.
Prescription medications are exempt, but over-the-counter drugs and vitamins are taxed. Clothing and shoes under $110 are exempt, but items over that threshold are taxed on the full amount. These exemptions explore statewide and do not change based on location.
Services are generally not taxed in California, though some specific services like repairs and alterations are. The CDTFA publishes detailed guidance on what is and is not taxable. When in doubt, ask the retailer or check the CDTFA website before making a large purchase.
How to calculate tax on a purchase
To find the tax on any purchase, multiply the price by the tax rate as a decimal. If an item costs $50 and your rate is 8.5%, multiply $50 by 0.085 to get $4.25 in tax. The total you pay is $50 + $4.25 = $54.25.
Most retailers calculate this automatically at checkout, so you see the tax broken out on your receipt. Online retailers show the tax before you complete the purchase. If you're budgeting or comparing prices between locations, do this calculation yourself to see the real cost difference.
For businesses, the calculation is the same but applies to every transaction. A business in a 9% tax area collects 9% on each sale and sends that money to the state. The CDTFA audits businesses to make sure they're collecting and reporting the correct rate.
When rates change and how to stay current
California sales tax rates change throughout the year as new voter-approved measures take effect. Most changes happen on January 1, April 1, July 1, or October 1, but some occur on other dates. The CDTFA publishes a calendar of upcoming changes on its website.
If you run a business, you must update your point-of-sale system before the effective date. Charging the old rate after the change is a violation, even if you did not know about it. The CDTFA sends notices to registered businesses, but it is your responsibility to stay informed.
For consumers, the main impact is knowing what you'll pay. If you're making a large purchase near a rate change date, check whether the rate is about to go up. Some people time big purchases to avoid a pending increase, though the difference is usually small.
Frequently Asked Questions
What is the highest sales tax rate in California?
The highest combined rate is over 10% in some areas, though the exact maximum varies by year as new local measures take effect. The CDTFA website shows the current highest rates by county. Most of California's population lives in areas with rates between 8% and 9.5%.
Do I pay sales tax on online purchases shipped to California?
Yes. Online retailers must collect California sales tax on orders shipped to California addresses. The rate applied is the one for the delivery address, not the retailer's location. This applies whether you buy from a California business or an out-of-state one.
Is sales tax the same in every city in my county?
No. Each city can set its own local rate, so two cities in the same county often have different totals. The county rate is the same throughout the county, but the city rate stacks on top of it differently depending on where you are.
Can I deduct sales tax I paid on my state income tax return?
California does not allow a deduction for sales tax paid. You can only deduct state income tax or property tax on your federal return, and only if you itemize deductions. Sales tax is not deductible at the state or federal level.
What happens if a retailer charges me the wrong rate?
If you are overcharged, ask the retailer for a refund. Most will correct it when ready. If a retailer consistently charges the wrong rate, you can report it to the CDTFA. Businesses that charge incorrect rates face penalties and audits.
