When Do You Owe Use Tax?
You owe use tax whenever you store, use, or consume a taxable item in your state, but no sales tax was collected at the time of purchase.
You generally encounter use tax in three distinct scenarios:
- Out-of-state purchases: Vendors without a physical or economic presence (nexus) in your state may not collect sales tax. You must report and pay the tax on these items yourself.
- Inventory withdrawals: You buy stock for resale (which you bought tax-free with a resale certificate) but then consume that product. Since you "used" it instead of "selling" it, you now owe the state use tax on that item.
- Buying from states with no sales tax: You drive across the border to a state with no sales tax to buy equipment for your business and use it in your home state, where there is sales tax.
How to Calculate Use Tax
Your use tax rate matches your local sales tax rate.
The formula works like this:
- (Purchase Price + Shipping/Handling) X Your Local Sales Tax Rate = Use Tax Owed
Many states often tax shipping and delivery charges. So, if you paid $1,000 for a desk and $50 for shipping, your taxable base is $1,050.

If you already paid sales tax to another state at the time of purchase (but at a lower rate than your home state's), you usually only owe the difference.
How to Report Use Tax
How you report use tax depends entirely on the state. While it is common to report use tax directly on your regular monthly or quarterly sales tax return, this isn't a universal rule. Some states (like Colorado, for example) require you to file a completely separate return just for use tax.
With that in mind these are the two most common ways to file:
- Sales tax return: If you currently file a sales tax return, you typically add your use tax to a designated line item, such as "Taxable Purchases."
- The Math: Total Due = (Tax Collected from Customers) + (Use Tax You Owe).
- Separate return: If you don't make taxable sales, some states require a separate Consumer Use Tax return.
- The Math: Total Due = (Use Tax You Owe).
How to Manage Use Tax
Filing in the form is simple, but the record-keeping behind it requires a lot of attention to detail.
Consider a standard month for a growing business:
- You give away 50 t-shirts at a local conference.
- You use specialized 3D printer filaments for a demo.
- You buy an office chair from an out-of-state vendor who charges zero sales tax.
To accurately calculate that one line on your tax return, the best practice is to track every single promo t-shirt, filament roll, and tax-free invoice.
While tracking these items is often still required, how hands-on you need to be depends entirely on your systems and sales channels. It requires a lot of attention to detail, but you don't have to figure out the workflow alone.

FAQs
Do I owe use tax on purchases from other countries?
Yes. If you buy equipment or software from a vendor overseas and they do not charge you your state's sales tax, you still owe use tax when you use that item in your business.
Do I owe use tax on promotional items or free company swag?
If you buy branded t-shirts or pens tax-free to give away to customers, you owe use tax on them. Since you are giving the items away for free, the state considers you the end consumer.
Is there a minimum threshold for use tax?
For businesses, there is usually no minimum threshold. Technically, if you buy a $10 pack of folders tax-free, you owe the cents on that purchase. This is exactly why auditors find it so easy to catch mistakes.
How far back can an auditor look for unpaid use tax?
Usually, auditors look back three to four years. However, if you have never filed a use tax return or reported it on your sales tax return, the statute of limitations never actually starts. This means they can look back as far as they want.
Are there any exemptions for use tax?
Yes. The rule of thumb is that if an item is exempt from sales tax, it is also exempt from use tax. For example, if your state exempts certain manufacturing machinery from sales tax, you will not owe use tax on it either.
Why doesn't standard accounting software catch use tax?
Most standard accounting platforms only track the money coming in from your sales. They do not automatically analyze the bills you pay. Unless you manually flag a vendor invoice as needing use tax, the software will completely ignore it.
What should I do if I realize I owe years of unpaid use tax?
Do not panic, and do not just start filing old returns. You should look into a Voluntary Disclosure Agreement (VDA) with your state. A VDA allows you to come forward anonymously, pay what you owe for a limited number of years, and usually get the penalties waived.
