How to Use This Use Tax Calculator

Enter the purchase amount, your home state tax rate, and any sales tax already paid (to an online seller or another state). The use tax owed is the difference between what your state would charge and what you already paid.

The Formula

Tax at home state rate = purchase amount Γ— home state rate
Credit for tax paid = min(tax already paid, tax at home state rate)
Use tax owed = max(0, tax at home state rate βˆ’ credit for tax paid)
Net tax rate = use tax owed Γ· purchase amount

Example

$800 laptop purchased online, no sales tax collected, California resident (7.25% state rate):
Tax at CA rate: $800 Γ— 7.25% = $58.00
Tax already paid: $0
Use tax owed: $58.00

If you bought it in Nevada and paid 6.85% ($54.80):
Use tax owed: $58.00 βˆ’ $54.80 = $3.20

How to report use tax: Most states allow you to report use tax on your annual state income tax return (look for a use tax line). Some states require a separate use tax return for businesses. Keeping track of all out-of-state purchases throughout the year makes reporting easier. Many accounting software programs have use tax tracking features for businesses.

Frequently Asked Questions

What is use tax and when do I owe it?
Use tax is a tax on the use, storage, or consumption of goods in your state when sales tax was not collected at the time of purchase. You owe use tax when you buy taxable items from out-of-state sellers (including online retailers) who did not collect your state's sales tax, and when you bring purchased items into your state from another state or country.
How does use tax differ from sales tax?
Sales tax is collected by the seller at the point of sale. Use tax is self-reported by the buyer when sales tax was not collected. The rate is usually the same as your state's sales tax rate. They are complementary taxes β€” the goal is to ensure the same items are taxed regardless of where they are purchased, preventing competitive disadvantage for local businesses.
Do I have to report use tax on my state tax return?
Many states include a use tax line on their individual income tax returns. Most taxpayers who buy taxable goods online without paying sales tax are required to report and pay use tax. In practice, enforcement is difficult for individual consumers, but the legal obligation exists. Businesses are audited more frequently and use tax compliance is strictly enforced for companies.
What can I subtract when calculating use tax?
You can reduce your use tax by any sales tax already paid to another state. If you paid 4% sales tax in a state with a 4% rate, and your home state rate is 7%, you owe the 3% difference as use tax. You never pay more than your home state's rate in combined tax, but you do owe the difference if you paid less elsewhere.
Which types of purchases commonly trigger use tax?
Common use tax situations: online purchases from small retailers without nexus in your state, furniture and appliances ordered from out-of-state showrooms, artwork purchased at out-of-state galleries, vehicles or boats purchased in low-tax states, software and digital products from foreign vendors, and business equipment purchased during trade shows in other states.
