What California's Use Tax Is

Use tax is a tax California charges on items you buy outside the state and bring in, or buy online from sellers who don't collect California sales tax. It exists because sales tax and use tax are meant to work together—if you buy something in another state where sales tax wasn't charged, California wants that tax paid when you use the item at home.

The use tax rate matches your local sales tax rate, which combines the state rate (7.25%) plus any county and local additions. So if your area's total sales tax is 8.5%, your use tax is also 8.5%. You owe use tax on the full purchase price, just as you would if you'd bought the item in California.

Most people encounter use tax when buying from out-of-state retailers or online sellers. However, many large online retailers now collect California sales tax automatically, which means you don't owe use tax separately on those purchases. The tax is still paid—it's just collected at checkout instead of being your responsibility to report later.

Key Takeaways

  • Use tax applies to items bought outside California or from online sellers who don't collect California sales tax, and you owe it at your local sales tax rate.
  • Most major online retailers now collect California sales tax automatically, so you typically don't owe use tax on those purchases.
  • You report use tax on your California income tax return using Form 540, Schedule CA, or you can report it separately to the California Department of Tax and Fee Administration.
  • Use tax covers tangible goods like clothing, electronics, and furniture, but not services or items already taxed in another state.
  • The tax applies whether you buy in person during a trip out of state or order remotely from a seller with no California presence.

When You Actually Owe Use Tax

You owe use tax when you buy a physical item outside California and bring it into the state for use, storage, or consumption. This includes purchases made during vacations, road trips, or online orders from sellers who don't charge California tax. The key is that the item must be tangible—clothing, furniture, electronics, appliances, and vehicles all count.

Services do not trigger use tax. If you pay for a haircut, car repair, or consulting work in another state, you don't owe California use tax on it. Similarly, if you buy something in another state and that state already charged you sales tax, you don't owe California use tax on top of it—the tax was already paid.

The practical reality is that most people don't track and report small purchases. The California Department of Tax and Fee Administration knows this. They focus enforcement on larger purchases and businesses. However, the law technically requires you to report use tax on all taxable items, even a single shirt bought out of state.

How to Report Use Tax on Your Tax Return

If you owe use tax, you report it when you file your California income tax return. On Form 540 (California Resident Income Tax Return), you use Schedule CA to calculate and report use tax owed. The form asks you to list the total purchase price of items you bought outside California and bring into the state.

You don't need receipts for every item. Instead, you estimate based on your purchases during the year. Many people use a worksheet or straightforward add up major purchases they remember. If you bought a laptop for $1,200 out of state and a suitcase for $80, and your local sales tax rate is 8.5%, you'd owe tax on $1,280.

Alternatively, you can report use tax separately to the California Department of Tax and Fee Administration outside of tax season, though most people handle it through their income tax return. If you file electronically, the software typically walks you through the Schedule CA questions.

What Items Are Subject to Use Tax

Use tax applies to most tangible goods: clothing, shoes, electronics, furniture, appliances, tools, toys, books, and vehicles. If you can touch it and buy it, use tax likely applies. The rule is broad because the intent is to tax consumption of goods in California, regardless of where you bought them.

Some items have special rules. Groceries and prescription medications are generally exempt from sales tax in California, so they're also exempt from use tax. Items you buy for resale (if you're a business) may not be subject to use tax depending on your situation. Motor vehicles have their own registration and use tax rules handled through the Department of Motor Vehicles, not through your income tax return.

Digital goods—software, e-books, music, and streaming subscriptions—are treated differently. Some are taxable and some are not, depending on whether they're considered a permanent read or a temporary license. When in doubt, check the California Department of Tax and Fee Administration website or ask the seller whether California tax applies.

The Difference Between Sales Tax and Use Tax

Sales tax and use tax are designed to be two halves of the same system. Sales tax is charged at the point of sale when you buy something in California. Use tax is charged when you buy something outside California and bring it in. Together, they may support that goods consumed in California are taxed once, at the California rate, regardless of where the purchase happened.

If you buy a jacket in Nevada and bring it home to California, you owe California use tax on it. If you buy the same jacket in a California store, you pay California sales tax at checkout. Either way, the tax gets paid—the difference is when and to whom you pay it.

This system exists because without use tax, people could avoid California sales tax by shopping just across the border or online. Use tax closes that gap. It's why online retailers have increasingly started collecting California sales tax—they're collecting it upfront so customers don't have to track and report it themselves.

Common Situations Where Use Tax Applies

You buy electronics online from a seller with no California location and no sales tax is charged at checkout. You owe use tax on the purchase price. You drive to Nevada, buy a television, and bring it home. You owe California use tax. You order furniture from a company in Oregon that doesn't collect California tax. You owe use tax when it arrives.

You attend a conference in another state and buy a book at the event. If no sales tax was charged, you owe use tax on it. You inherit furniture from a relative in another state and move it to California. Use tax may explore, though some situations involving gifts or inheritances have different rules—check with the tax authority if the value is significant.

You buy a car in another state and register it in California. The Department of Motor Vehicles handles use tax on vehicles separately; it's not reported on your income tax return. You purchase clothing during a vacation and bring it back. Technically you owe use tax, though enforcement on small personal purchases is minimal.

Why Most People Don't Pay Use Tax on Small Purchases

Use tax is a self-reporting tax, which means you're responsible for calculating and reporting it yourself. The California Department of Tax and Fee Administration doesn't send you a bill or notice. They rely on people to report it honestly on their tax returns. This creates a situation where many people straightforward don't report use tax on small or occasional purchases.

The state's enforcement focus is on larger transactions and businesses. If you buy a single item for under $100 out of state, the likelihood of the state tracking it down is extremely low. However, if you regularly buy expensive items out of state or run a business that makes large purchases without paying tax, you're more likely to face scrutiny during an audit.

That said, the law requires reporting use tax on all taxable purchases, regardless of size. If you're filing your taxes accurately and want to follow the rules, you should report use tax owed. If you're unsure whether a specific purchase qualifies, the California Department of Tax and Fee Administration has resources on their website, or you can contact them directly.

Frequently Asked Questions

Do I owe use tax if I buy something online from Amazon or another big retailer?

Not usually. Amazon and most large online retailers now collect California sales tax automatically at checkout. When tax is collected, you don't owe use tax separately. Check your receipt—if sales tax appears on it, you're done. If no tax was charged and the seller has no California location, you owe use tax on the purchase price.

What if I buy something in another state and use it there, then move to California with it?

If you already paid sales tax in the other state, you don't owe California use tax. Use tax only applies when no sales tax was paid. If you bought the item tax-free and then moved to California, you technically owe use tax, though enforcement on personal household goods is rare.

Can I deduct use tax on my federal income tax return?

You cannot deduct use tax on your federal return. However, some states allow you to deduct state and local taxes (SALT) on your federal return, up to $10,000 per year. California sales and use tax combined may count toward that limit if you itemize deductions, but the rules are complex—consult a tax professional for your specific situation.

Do I need to keep receipts for use tax reporting?

You don't need receipts for every small purchase, but you should keep them for larger items. If you're audited, the state may ask for documentation of major out-of-state purchases. For routine reporting on your tax return, you estimate based on what you remember buying.

What happens if I don't report use tax I owe?

If you don't report use tax and the state discovers it during an audit, you'll owe the tax plus penalties and interest. The penalties can be significant—typically 25% of the unpaid tax. However, audits focusing on use tax are uncommon unless you're a business or made very large purchases.
