What Is Use Tax and When Do You Owe It?

Use tax is generally the purchaser-side counterpart to sales tax. It may become due when a taxable purchase is used, stored, or consumed in a state but the seller did not collect the sales tax that would otherwise apply. An exemption may remove the obligation, and the exact taxability, rate, reporting method, and deadline depend on state and local law.

This issue can affect both businesses and individuals. It often appears after an invoice review, an out-of-state purchase, or a transaction in which a vendor did not charge tax. Businesses should not assume that an untaxed invoice means the purchase was tax-free. They may need to determine whether use tax is due and, if so, how it must be reported.

A business that also makes taxable sales may have a separate registration responsibility. Our sales tax application information explains the registration process at a general level and provides access to state-specific details. Registration to collect sales tax and responsibility for use tax are related compliance issues, but they are not always the same obligation.

How use tax differs from sales tax

Sales tax and use tax generally address the same underlying concern: tax on taxable transactions should not depend solely on whether the seller collected tax at checkout. The practical difference is usually who handles the tax first.

• Sales tax: The seller generally calculates and collects the applicable tax from the customer as part of the transaction.
• Use tax: The purchaser may have to calculate and report the tax when the seller did not collect the required sales tax.

Use tax is not automatically due merely because an invoice shows no sales tax. The item or service must first be taxable under the relevant jurisdiction’s rules, the purchase must fall within that jurisdiction’s authority, and no applicable exemption may apply. Taxability can differ based on what was purchased, how it is used, who bought it, and where it is used or stored.

There is no single nationwide use-tax rate, return, deadline, or registration document. State and, where applicable, local rules control. The IRS does not administer a general federal use tax. For federal individual income-tax purposes, the IRS identifies general sales taxes as state and local taxes and allows eligible individuals to elect an itemized deduction for state and local general sales taxes instead of state and local income taxes, subject to federal limitations. That federal deduction rule does not create a nationwide use-tax rate or state filing obligation.

Because rates are jurisdiction-specific, a general comparison can be more useful than assuming that a familiar sales-tax percentage applies everywhere. The state sales and use tax rate overview can help identify where additional state-level research is needed, but the current state revenue department guidance should be checked for the transaction’s actual location and circumstances.

Who should review purchases for use tax

Any purchaser receiving untaxed invoices for potentially taxable goods or services should consider a use-tax review. That includes personal purchasers as well as businesses, although the return and payment method may differ.

For a business, useful review categories may include:

• Purchases from vendors that did not charge the destination state’s sales tax.
• Invoices on which tax was removed after an exemption or resale certificate was presented.
• Items originally purchased for resale but later used by the business rather than resold.
• Equipment, supplies, or other property delivered to one location and used or stored elsewhere.
• Purchases for which the vendor charged tax for a jurisdiction that may not match the place of use.

These categories are review signals, not automatic findings that tax is due. Exemptions, resale treatment, sourcing rules, and any credit for tax paid to another jurisdiction must be evaluated under the applicable state and local rules.

Texas provides a straightforward illustration of the purchaser-side rule. A Texas purchaser owes state and local use tax on taxable goods or services stored, used, or consumed in Texas when the seller does not charge Texas sales tax, unless an exemption applies. This rule applies to business and personal purchasers and is not limited to purchases from remote sellers.

That example also shows why an untaxed purchase should not be confused with seller nexus. A purchaser’s use-tax obligation can arise from the treatment of the purchase itself. It is not necessarily dependent on whether the purchaser knows why the seller did not collect tax.

How the amount and reporting method are determined

A practical use-tax review usually has three parts: determine whether the purchase is taxable, identify the location whose rules apply, and confirm the correct reporting route. Each part can affect the final amount or whether anything is due.

Determine the applicable tax treatment

Start with the invoice, purchase description, delivery information, and business purpose. Confirm whether the transaction is taxable and whether the purchaser has a valid exemption. If a resale or exemption certificate was used, verify that the actual use of the purchase remained consistent with that certificate.

Do not calculate use tax by copying a rate from another state or by applying only a state-level rate without checking possible local treatment. For example, Texas’s state use-tax rate is 6.25%, and up to 2% in additional local use tax may apply based on where the purchaser uses, stores, or consumes the item. Those figures describe Texas; they are not a national rate or an automatically combined rate for every Texas transaction.

Choose the correct reporting path

The reporting document may depend on whether the purchaser already holds a sales and use tax permit. In Texas, a purchaser holding a Texas Sales and Use Tax Permit reports use tax as “Taxable Purchases” on the Texas Sales and Use Tax Return. A purchaser without that permit uses Form 01-156, Texas Use Tax Return.

New York also distinguishes among purchaser types. A business registered or required to register for New York sales tax reports use tax on its sales and use tax return. An unregistered business other than a sole proprietorship generally reports it on Form ST-130, Business Purchaser’s Report of Sales and Use Tax. Separate rules apply to sole proprietors and individuals.

These examples should not be treated as interchangeable procedures. A state may use a regular sales and use tax return, a purchaser-specific return, or another reporting method. Check the relevant state’s current instructions before filing.

Practical steps for managing use tax

Use tax is easier to manage when it is incorporated into the accounts-payable process rather than addressed only at year-end. The goal is to create a consistent review trail without treating every tax-free invoice as taxable.

1. Flag invoices with no tax. Configure the purchasing or accounting process to identify potentially taxable transactions on which the vendor charged no sales tax.
2. Record where the purchase is used. Delivery location may not always tell the whole story. Keep records showing where property is stored, used, or consumed when that location matters to the state’s rules.
3. Document exemptions. Retain certificates and supporting records for purchases treated as exempt or for resale. If the use of an item changes, review whether the earlier treatment still applies.
4. Separate research from calculation. First determine whether the transaction is taxable and which jurisdiction applies. Then calculate the amount under the current state and local rules.
5. Reconcile before filing. Compare the use-tax workpaper with untaxed expense accounts, fixed-asset purchases, and vendor records. Investigate differences before submitting the return.
6. Keep an audit trail. Preserve invoices, tax calculations, exemption support, location information, and evidence of any tax already paid.

If an omitted purchase is found after a return has been submitted, the proper correction depends on the jurisdiction and circumstances. The discussion of whether a sales tax return can be amended after filing explains the general correction considerations. Businesses should use the state’s current amendment or disclosure procedures rather than simply adding an old transaction to a later return without confirming that treatment.

Deadlines and ongoing compliance

Use-tax compliance is not necessarily an annual exercise. The filing schedule can depend on the state, the purchaser’s registration status, the type of return, and other state-specific rules. A business already filing sales and use tax returns may report use tax on its assigned schedule, while a purchaser without a permit may use a different return and deadline.

Texas illustrates how filing obligations can change based on both permit status and the amount owed. A nonpermitted Texas purchaser owing less than $1,000 in use tax must file and pay by January 20 of the following year. After the purchaser reaches $1,000 or more in use tax during a calendar year, filing and payment are due by the 20th day of the following month. The $1,000 measure is the use tax owed, not sales or gross receipts.

Businesses should periodically confirm that their filing schedule still matches state records. Filing frequency can change under state procedures, and businesses should not begin using a different schedule solely because transaction volume has changed. Additional guidance is available on changing a sales tax filing frequency.

Permit maintenance should also remain separate from transaction review. Some registrations or certificates may have renewal or updating requirements, while others may remain active until closed or otherwise changed under state rules. The overview of sales tax renewals and expired state tax certificates explains why businesses should verify each jurisdiction’s current requirements rather than assume every permit renews annually.

A sound ongoing process combines invoice review, exemption documentation, jurisdiction-specific rate research, timely reporting, and periodic reconciliation. That approach helps distinguish genuinely exempt purchases from transactions on which the purchaser—not the seller—must account for the tax.
