California Sales Tax: The Basics

California sales tax is a tax added to the price of most goods you buy in the state. When you purchase something at a store, online, or from a restaurant, the seller adds this tax to your bill at checkout. The state collects this money and distributes it to state and local governments.

The total sales tax rate you pay depends on where you are in California. The state sets a base rate of 7.25%, but cities and counties add their own local taxes on top of that. This means your actual rate could be anywhere from 7.25% to over 10%, depending on your location. For example, if you buy a $100 item in one county, you might pay $7.50 in tax, but the same item in another county could cost you $9.50 in tax.

Key Takeaways

  • California's base sales tax rate is 7.25%, but your actual rate includes local additions that vary by city and county.
  • Sales tax applies to most physical goods, but not to groceries, prescription medications, or most services.
  • You pay sales tax at the point of sale for in-store purchases, and it is included in the total price for most online orders shipped to California.
  • The tax you pay goes to state and local governments for schools, roads, and public services.
  • Some items are taxed differently depending on how they are sold or what category they fall into.

What Gets Taxed and What Does Not

Not everything you buy is subject to sales tax. Groceries — including bread, milk, vegetables, and meat — are not taxed. Prescription medications filled by a pharmacist are also exempt. However, vitamins, supplements, and over-the-counter medicines are taxed as regular goods.

Most services are not taxed. A haircut, dental work, car repair, or plumbing service does not have sales tax added. But if you buy a physical product as part of that service — like a bottle of shampoo at the salon or a replacement part for your car — that product portion may be taxed.

Clothing and shoes are taxed in California, unlike some other states. Restaurant meals and prepared foods are taxed, but unprepared groceries are not. Digital goods like e-books, music downloads, and software subscriptions are taxed. If you are unsure whether something is taxed, the receipt will show the amount.

How Your Local Rate Is Calculated

Your sales tax rate is built in layers. The state contributes 7.25% of the base rate. On top of that, your county adds a percentage, and then your city or district may add another percentage. Some special districts — for transit, schools, or other services — can add their own portion too.

This is why two stores just a few miles apart in different cities can have different tax rates. A purchase in San Francisco may be taxed at 8.625%, while the same purchase in Oakland is taxed at 10.25%. You can find your exact local rate by entering your address on the California Department of Tax and Fee Administration website, or by checking your receipt from a recent purchase.

Sales Tax on Online and Out-of-State Purchases

If you order something online and it ships to a California address, sales tax is usually included in the total price you pay. Most large online retailers now collect California sales tax automatically at checkout. The rate applied is based on the delivery address, not where the company is located.

If you buy something from an out-of-state seller who does not collect California sales tax, you are technically responsible for paying use tax — which is the same rate as sales tax — when you receive the item. In practice, most people do not report this, but the law requires it. If you run a business and make regular purchases from out-of-state suppliers, you may need to track and report use tax on your tax return.

Who Collects and Where the Money Goes

The seller — whether a store, restaurant, or online retailer — collects sales tax from you and then sends it to the state. Businesses file sales tax returns monthly or quarterly, depending on their size. The California Department of Tax and Fee Administration oversees this process.

Once collected, the money is split between the state and local governments. The state uses its portion for schools, infrastructure, and state services. Cities and counties use their portions for local schools, police, fire departments, libraries, and public works. The exact breakdown varies by location and what local taxes were approved by voters.

Special Cases and Exceptions

Some groups are exempt from paying sales tax on certain purchases. Nonprofit organizations, government agencies, and Native American tribes may not pay tax on items they buy for official use. If you are part of one of these groups, you typically need to provide a resale certificate or exemption document to the seller.

Resellers — people who buy items to resell them — can avoid paying sales tax on their purchases by providing a resale certificate. This prevents the same item from being taxed twice: once when the reseller buys it, and again when the customer buys it. If you run a small business and buy inventory, ask the seller about a resale certificate.

Checking Your Receipt and Understanding the Breakdown

Your receipt shows the subtotal before tax, the tax amount, and the final total. The tax line usually shows the rate applied or the dollar amount. If you want to verify the math, multiply the subtotal by your local tax rate. For example, a $50 purchase in a 8.5% tax area should have $4.25 added, for a total of $54.25.

If you notice a tax rate on your receipt that seems wrong, check the California Department of Tax and Fee Administration's rate lookup tool to confirm what your area's rate should be. Occasionally a store applies the wrong rate by mistake, though this is rare. If you find an error, you can contact the store or the tax department.

Frequently Asked Questions

Why does my sales tax rate change depending on where I shop?

California allows cities and counties to add their own local sales taxes on top of the state's 7.25% base rate. A store in one city might be in a different tax district than a store a few miles away, even if they are in the same county. Your address at checkout determines which local taxes explore.

Do I have to pay sales tax on groceries?

No. Unprepared food items like bread, milk, vegetables, meat, and canned goods are not taxed. However, prepared foods from a deli counter, restaurant, or bakery are taxed. Vitamins, supplements, and non-prescription medicines are also taxed because they are not considered food.

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. The rate is the same as sales tax for your location. You are legally required to report and pay it, though enforcement for individual purchases is rare. Businesses are more likely to be audited on use tax.

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

Generally, no. Sales tax is a final cost of the purchase. If you return an item and get a refund, the sales tax is refunded as part of that refund. If you paid tax on something you later found out was exempt, you would need to contact the seller or the tax department to request a correction.

How do I find out what the sales tax rate is in my city?

Visit the California Department of Tax and Fee Administration website and use their sales tax rate lookup tool. Enter your address or zip code, and it will show you the exact combined state and local rate for your location. You can also check a recent receipt from a local purchase to see what rate was applied.
