Understanding use tax obligations for untaxed out-of-state purchases is vital for individuals and businesses. With the rise of e-commerce, many consumers buy goods from sellers outside their state without paying sales tax at the time of purchase, creating the responsibility to pay use tax under state laws.
This article examines how to identify taxable purchases, calculate use tax owed, and fulfill filing requirements. It also addresses exemptions, enforcement measures, and penalties for non-compliance.
Determining Which Purchases Are Taxable
Use tax applies to tangible personal property purchased out-of-state and brought into your home state for use, storage, or consumption. Items like electronics, furniture, and clothing are common examples. The purpose of the tax is to ensure local businesses compete fairly with out-of-state sellers.
The taxability of a purchase depends on its nature and intended use. For instance, if a business buys office equipment from an out-of-state vendor that doesn’t collect sales tax, the business must remit use tax. Similarly, individuals buying goods from online retailers without a physical presence in their state may be liable. The tax rate typically matches the local sales tax rate, which varies by jurisdiction.
Some purchases are exempt, such as items for resale or those used in manufacturing. State-specific rules govern these exemptions. For example, some states exempt agricultural equipment or renewable energy systems. Digital goods, like software downloads or streaming services, may also be taxable depending on state laws.
Calculating the Amount Owed
To calculate use tax, determine the applicable rate—usually the combined state and local sales tax rate where the item will be used. For example, if the state rate is 6% and the local rate is 1.5%, the total use tax rate is 7.5%. State tax agency websites provide current rates, which can change annually.
The tax base is generally the purchase price, and it may include shipping or handling when those charges are part of the sale. Discounts typically reduce the taxable amount; manufacturer rebates may not in many states. For example, if equipment is purchased for $1,000 with a $100 discount, the taxable amount is $900. At a 7.5% rate, the use tax owed would be $67.50.
Proper documentation is essential. Retain receipts, invoices, and records to substantiate the purchase price and ensure accurate reporting. Businesses, in particular, should maintain detailed records, as audits may require proof of compliance. Accounting software can simplify calculations and record-keeping, minimizing the risk of errors.
Filing and Documentation
Filing use tax obligations varies by state. Many states allow individuals to report and pay use tax on their state income tax return and provide estimated-use-tax lookup tables to simplify reporting for smaller purchases. In California, individuals can report use tax on the state income tax return and may use either a worksheet or an estimated-use-tax table, depending on their situation.1Franchise Tax Board. Use Tax
Some states require businesses to file returns monthly, quarterly, or annually based on liability or filing frequency. For example, Tennessee sets due dates by filing frequency: monthly and quarterly filers generally file by the 20th of the following month, while annual filers file by January 20.2Tennessee Department of Revenue.

For businesses, accurate record-keeping is critical. Documentation—such as invoices, proof of payment, and item descriptions—should be organized and readily available. States may request records from several years back during an audit. Accounting software designed for tax compliance can streamline documentation and reporting.
Individuals with minimal out-of-state purchases may use tools like state-provided lookup tables, which estimate use tax based on income levels. However, large purchases, such as vehicles or expensive electronics, require detailed records to ensure accurate reporting and avoid disputes.
Exemptions and Special Circumstances
Exemptions from use tax are determined by state regulations. Items purchased for resale are typically exempt since the final consumer bears the tax burden. Businesses must use resale certificates to claim these exemptions and maintain them for audit purposes.
Some states offer specific exemptions for industries or economic initiatives. For example, Texas exempts qualifying manufacturing machinery and equipment used directly in manufacturing tangible personal property for sale.3Texas Comptroller of Public Accounts.

Enforcement Measures
State tax authorities employ various strategies to enforce compliance with use tax laws. These include cross-referencing vendor sales data with taxpayer filings to uncover discrepancies.
Audits are a common enforcement tool. They may be random or targeted, focusing on taxpayers suspected of underreporting. Businesses should expect auditors to scrutinize accounting records, invoices, and filings. Some states collaborate with other jurisdictions to track cross-border transactions that may have escaped taxation. Accurate reporting and organized records are critical to avoid costly and time-consuming audits.
Penalties for Failure to Report and Pay
Failing to report and pay use tax can result in significant penalties, including fines and interest on unpaid amounts. In New York, for example, the late-filing and late-payment penalties for sales and use tax are 10% for the first month plus 1% for each additional month, up to 30%, and interest is compounded daily with rates set quarterly.5New York State Department of Taxation and Finance.

Some states offer voluntary disclosure programs, allowing taxpayers to report unpaid use taxes with reduced lookback periods and potential penalty relief. California’s In‑State Voluntary Disclosure Program limits the assessment period to three years and allows the tax agency to waive late-filing and late-payment penalties for qualifying applicants.6California Department of Tax and Fee Administration.
