California sales tax is a tax added to the price of most goods you buy in the state

When you buy something at a store in California, the cashier adds sales tax to your total. That tax goes to the state and to your local city or county. The rate you pay depends on where you are in California — it is not the same everywhere. The state sets a base rate, but cities and counties add their own local taxes on top of it, so your final rate can range from 7.25% to over 10% depending on your location.

Sales tax is different from income tax. You do not file paperwork for it — it is calculated and collected right at the register. If you buy a $100 item in one California county, you might pay $107.25 in tax. In another county, the same item might cost $109.50. The difference comes from local add-ons.

Key Takeaways

  • California's base sales tax rate is 7.25%, but your actual rate includes local taxes added by your city or county, making it higher in most places.
  • Sales tax applies to most physical goods but not to services like haircuts, repairs, or professional fees.
  • Groceries, prescription medications, and some medical equipment are exempt from sales tax in California.
  • You can find your exact local sales tax rate by entering your zip code on the California Department of Tax and Fee Administration website.
  • Online purchases are subject to California sales tax if the seller has a physical presence in the state or meets certain sales thresholds.

How the state and local tax rates combine

California's base state sales tax rate is 7.25%. This is what the state government collects. On top of that, your county adds a tax, and your city may add another one. These local rates vary widely. Some counties add 0.5%, others add 1.5% or more. Some cities add an additional 0.25% to 1%.

The result is that your total sales tax rate depends entirely on your zip code. A purchase in San Francisco has a different tax rate than the same purchase in Los Angeles or in a rural area. You cannot predict your rate without knowing your exact location. The California Department of Tax and Fee Administration publishes a lookup tool where you enter your zip code and it shows you your combined rate.

This system exists because California lets local governments fund their own services through sales tax rather than relying only on state money. A city that wants to improve schools or roads can raise its local sales tax rate, and residents in that city pay the higher rate.

What items are taxed and what are not

Most physical goods are taxed. Clothing, electronics, furniture, toys, and household items all have sales tax added at checkout. However, services are not taxed. If you pay for a haircut, a plumber's labor, a doctor's visit, or car repair work, there is no sales tax on the service itself. (If the plumber sells you a part, that part is taxed, but the labor is not.)

Some goods are exempt from sales tax in California. Groceries — unprepared food you cook at home — are not taxed. This includes bread, milk, vegetables, meat, and canned goods. However, prepared foods, hot foods, and items from a deli counter are taxed. Soda and candy are also taxed because they are not considered groceries.

Prescription medications are exempt from sales tax. Over-the-counter medicines like aspirin or cold medicine are taxed. Medical equipment prescribed by a doctor — such as wheelchairs, hearing aids, or diabetic supplies — is typically exempt, but the rules vary by item. If you are unsure whether a medical item is exempt, ask the pharmacist or retailer.

Sales tax on online and out-of-state purchases

If you buy something online from a California seller, sales tax is added just as it would be in a physical store. The seller collects it and sends it to the state. This applies whether you pick up the item in a store or have it shipped to your home.

If you buy from an out-of-state seller, the rule depends on whether that seller has a physical presence in California — a warehouse, office, or store location. If they do, they must collect California sales tax. If they do not, they typically do not collect it at checkout. However, California law requires you to pay "use tax" on those purchases yourself when you file your state income tax return. In practice, most people do not report this, but it is technically owed.

Large online retailers like Amazon, Walmart, and Target have California locations, so they collect sales tax on all California orders. Smaller sellers may not have a presence here, so the tax situation depends on the specific seller.

Who collects the tax and where it goes

The retailer or seller collects sales tax at the point of sale. They hold onto the money temporarily, then send it to the California Department of Tax and Fee Administration. That department splits the revenue: the state keeps its portion, and the rest goes to the county and city where the purchase was made.

Local governments use this money for schools, roads, public safety, and other services. Because the tax rate varies by location, wealthier areas with higher sales volumes collect more tax revenue, while rural or lower-income areas collect less. This is one reason California cities and counties have different funding levels for public services.

Sellers are required to report their sales tax collections monthly or quarterly, depending on their sales volume. Large retailers report monthly. Small businesses may report quarterly. The state audits these reports to make sure the correct amount is being collected and sent in.

Special situations and exceptions

Resale certificates allow businesses to buy goods without paying sales tax if they plan to resell those items. A clothing store, for example, does not pay sales tax when it buys inventory from a wholesaler. The tax is paid only when the customer buys the finished item. This prevents the same item from being taxed multiple times as it moves through the supply chain.

Some nonprofits and government agencies are exempt from sales tax on their purchases. A school district buying supplies, for instance, does not pay sales tax. Churches and certain charitable organizations may also be exempt, though the rules are specific and require documentation.

If you buy something and later return it, the sales tax is refunded along with the purchase price. If you exchange an item for a different one, you pay sales tax only on the difference in price. These are handled at the register when you process the return or exchange.

How to find your exact local sales tax rate

Your sales tax rate is determined by your zip code. The easiest way to find it is to visit the California Department of Tax and Fee Administration website and use their sales tax rate lookup tool. Enter your zip code, and it shows you the combined state and local rate for that area.

You can also call your city or county tax assessor's office and ask for your local sales tax rate. They can tell you the breakdown: how much is state tax, how much is county tax, and how much is city tax.

If you are a business owner, you need to know your rate so you can collect the correct amount from customers and report it accurately. If you are a consumer, knowing your rate helps you estimate the final cost of a purchase before you reach the register.

Frequently Asked Questions

Why does California have different sales tax rates in different places?

California allows counties and cities to add their own local sales tax on top of the state's base rate. This lets local governments fund schools, roads, and services without raising income taxes. Each area decides whether to add a local tax and how much.

Do I have to pay sales tax on everything I buy?

No. Services are not taxed, and certain goods like groceries and prescription medications are exempt. Most physical goods are taxed, but there are exceptions. If you are unsure about a specific item, ask the retailer before you buy.

What is use tax and do I have to pay it?

Use tax is a tax on items you buy from out-of-state sellers who do not collect California sales tax. You are supposed to report and pay it yourself on your state income tax return. Most people do not report it, but it is technically owed on those purchases.

Does sales tax explore to online purchases from California sellers?

Yes. If you buy from a California seller online, sales tax is added to your order just as it would be in a physical store. The rate depends on where the item is being shipped or picked up.

Can I get a refund of sales tax I already paid?

If you return an item, the sales tax is refunded along with the purchase price. If you exchange an item for a different one, you pay tax only on the price difference. Both are handled at the register when you process the transaction.
