Understanding California Sales Tax Rules and Rates

How California Sales Tax Works

California imposes a statewide sales tax on most goods and some services. The state sales tax rate is 7.25%, which applies to all purchases across California. However, the total tax you pay often exceeds this percentage because counties and local jurisdictions can add their own sales taxes on top of the state rate. This means your actual sales tax rate depends on where you make the purchase.

The sales tax is collected by retailers at the point of sale. When you buy an item, the store calculates the tax based on the location where the transaction occurs, not where you live. For example, if you live in Los Angeles County but make a purchase in San Francisco, the San Francisco sales tax rate applies to your purchase. This location-based system is important because California has significant variation in total tax rates across different areas.

The California Department of Tax and Fee Administration (CDTFA) oversees sales tax collection and enforcement. Retailers must register with the CDTFA, collect the appropriate tax, and remit it to the state and local authorities. Large retailers with significant presence in California must collect sales tax regardless of whether they have a physical store location in the state. This includes online retailers, which have been required to collect California sales tax on purchases shipped to California addresses since 2019.

Understanding how sales tax applies to your purchases helps you understand your final costs at checkout. The sticker price you see on an item is not the final price you'll pay—you need to add the applicable sales tax for your location. When budgeting for purchases or comparing prices between different areas, remembering that sales tax varies by location prevents surprises at the register.

Practical Takeaway: Your total sales tax rate is the 7.25% state rate plus your county and local district taxes. Look up your specific rate on the CDTFA website by entering your zip code or address to know your exact tax percentage.

Sales Tax Rates by County and Location

California's 58 counties have different combined sales tax rates because local jurisdictions add taxes above the state rate. These additional local taxes fund specific purposes like transportation, infrastructure, education, and public services. The combined rate you pay is the sum of the state rate (7.25%) plus all applicable local district taxes in your area.

Some examples of total sales tax rates across California show the variation: Los Angeles County has a combined rate of 9.5%, San Francisco County has 8.625%, San Diego County has 7.75%, and Fresno County has 8.375%. Some areas in rural Northern California have rates closer to 7.25% because fewer local districts have added taxes. The highest combined rates in the state exceed 10% in some locations. This variation means a $100 purchase costs different amounts depending on where you shop.

Within each county, different cities and special districts may have their own additional sales taxes. For instance, a city in Los Angeles County might add an extra local tax beyond the county rate, creating multiple layers of taxation. A shopping district or transit district might also have its own tax. All these layers combine to create the final rate for that specific location. This is why two stores in the same county can have slightly different tax rates if they're in different cities or districts.

The CDTFA publishes detailed sales tax rate tables for every zip code and address in California. You can search by zip code, address, or city to find the exact rate that applies in that location. These rates change periodically when counties or districts approve new taxes or when existing taxes expire. The CDTFA website updates these changes regularly, and you can set up notifications to learn about rate changes in specific areas.

Practical Takeaway: Visit the CDTFA website and search your zip code to find your exact combined sales tax rate. If you shop in multiple locations, look up rates for each area to understand how tax affects your purchases across different regions.

What Items Are Subject to Sales Tax

Most tangible goods sold in California are subject to sales tax. This includes clothing, electronics, furniture, groceries, beverages, household items, and countless other physical products. When you purchase these items from a retailer, the seller must add the applicable sales tax. The general rule is that if the item is a physical good that you can touch and take with you, it's probably subject to sales tax.

Some items have special rules or reduced tax rates. Unprepared food items like raw vegetables, meat, and dairy products are not subject to sales tax in California. This means buying groceries like potatoes, chicken, milk, and eggs at a supermarket is tax-free. However, prepared food items are taxable—if you buy a prepared salad, rotisserie chicken, or a smoothie from a store, sales tax applies. Hot prepared food is always taxable. Beverages also receive different treatment: plain water and milk are not taxable, but soda, juice, and other flavored beverages are taxable.

Certain services are subject to sales tax in California, though the rules are more complex than for goods. Repairs to personal property, labor for installation or assembly, and some maintenance services are taxable. However, professional services like accounting, legal advice, and medical care are generally not subject to sales tax. Haircuts, spa services, and beauty treatments are taxable in California. Hotel stays, car rentals, and parking are taxable. Digital products present interesting cases—digital books are subject to tax, digital music is taxable, and online software subscriptions can be taxable depending on the service.

Prescription medications are exempt from sales tax in California, protecting consumers from additional costs for necessary medical treatments. Medical devices prescribed by a physician may also be exempt. However, over-the-counter medications and health supplements are generally subject to sales tax. This distinction exists because the state wants to reduce the financial burden on people purchasing medically necessary items.

Practical Takeaway: When shopping for groceries, unprepared food items have no sales tax, but prepared foods and beverages do. Check receipts carefully to understand what portions of your purchase are taxable, and remember that different stores may prepare items differently, affecting their tax status.

Sales Tax Rules for Online and Out-of-State Purchases

California requires online retailers and out-of-state sellers to collect sales tax on purchases delivered to California addresses. This rule applies to major online retailers, marketplaces, and smaller sellers who meet certain thresholds. The change significantly affects online shopping because many online shoppers previously believed they could avoid sales tax through online purchases. Now, most online purchases to California addresses are subject to the sales tax rate of the California location where the item will be delivered.

The federal Wayfair decision in 2018 allowed states to require out-of-state retailers to collect sales tax without having a physical presence in the state. California implemented this requirement, and the CDTFA began enforcement. Any retailer with sufficient sales activity to California—currently set at more than $100,000 in annual sales in the prior calendar year—must register with the CDTFA and collect tax. This includes Amazon, eBay, Walmart, Target, and countless smaller online retailers. These businesses collect the tax at checkout, and the total tax rate depends on your delivery address.

For purchases shipped outside California and then brought into the state, California consumers may owe "use tax," which is essentially the flip side of sales tax. If you buy an item from an out-of-state retailer who didn't collect California tax, you may technically owe tax on that item. In practice, individual consumers are rarely audited for use tax, but it remains a legal obligation. Businesses are more likely to face audits and requirements to pay use tax on items they've purchased outside California and used in the state.

The practical effect for most California shoppers is straightforward: online purchases are now taxed the same way as in-store purchases. The tax rate applied depends on your delivery address, not your location at the time of purchase. If you order from your home in Los Angeles, the Los Angeles County rate applies. This creates consistency between online and offline shopping and reflects the modern reality that online retailers operate across state lines.

Practical Takeaway: Expect to pay California sales tax on most online purchases delivered to California addresses, regardless of where the retailer is located. Enter your address accurately at checkout to ensure the correct tax rate is applied, and review your receipt to verify the correct tax was charged.
