Key takeaways
– A use tax is a tax on tangible goods (and sometimes certain services) that you buy out of state (or online) without paying the sales tax charged in your home jurisdiction, but which you bring into and use in your home state.
– The use tax rate is generally the same as the local/state sales tax rate (state + local combined). Consumers are typically expected to self‑assess and remit the tax when the seller did not collect sales tax.
– Use tax helps protect in‑state businesses from unfair out‑of‑state competition and ensures states collect revenue from purchases made outside their borders. Enforcement can be difficult, though many states now require remote sellers to collect tax after the 2018 Supreme Court decision in South Dakota v. Wayfair, Inc.
– Failure to report and pay use tax can result in interest and penalties; rules and filing channels vary by state.
What the use tax means
– Definition: Use tax is a complement to sales tax. It applies when you purchase taxable items (or taxable services in some states) outside your taxing jurisdiction without paying sales tax, and you bring those items into your home jurisdiction for storage, use, or consumption.
– Scope: Use tax generally applies to tangible personal property (furniture, electronics, vehicles, etc.). Some states exclude certain categories (for example, many states exempt most groceries).
Why use tax exists
– Fair competition: It prevents out‑of‑state sellers who don’t collect sales tax from undercutting local retailers who must collect and remit sales tax.
– Revenue integrity: It helps states recapture tax revenue from purchases made where no sales tax was charged.
– Completeness: It ensures residents contribute to funding local and state public services regardless of where they shop.
How use tax works (mechanics)
1. Purchase outside your taxing jurisdiction (including some online purchases) where sales tax was not collected.
2. You bring the item into your home state to use, store, or consume it.
3. You determine the applicable tax rate (your combined state and local sales tax rate).
4. You calculate the tax: purchase price × applicable rate.
5. You remit that tax to your state through a designated channel (state income tax return line, separate use tax return, or a special form).
6. If you later are audited and didn’t pay, you may owe tax plus interest and penalties.
Comparing use tax and sales tax
– Sales tax: Collected by the seller at point‑of‑sale and remitted to taxing authorities. Seller calculates and collects the tax from the buyer.
– Use tax: Self‑assessed by the buyer when the seller did not collect sales tax. The tax rate is usually the same as the sales tax rate for the buyer’s jurisdiction.
– Practical difference: Sales tax enforcement relies on seller collection; use tax enforcement relies on purchaser reporting. Since sellers historically didn’t always have to collect sales tax for out‑of‑state buyers, the use tax was the backstop.
The connection between use tax and nexus
– Nexus determines whether a seller must collect sales tax for a state. Traditionally physical presence (store, warehouse, employee) created nexus.
– After South Dakota v. Wayfair, Inc. (2018), states can impose sales‑tax collection obligations on remote sellers based on economic or virtual contacts (economic nexus), not only physical presence. As a result, many e‑commerce sellers now collect sales tax for buyers in those states, reducing the number of consumer‑remitted use tax cases.
– If a remote seller still does not collect tax, the buyer remains responsible for use tax.
Example: How use tax applies (California example)
– Scenario A: You buy a sofa in California from a local retailer. The retailer collects sales tax at checkout and remits it. No use tax is due.
– Scenario B: You buy the same sofa while in a state with no sales tax (or from an online seller that didn’t collect tax) and bring it back to California. You owe California use tax based on California’s combined rate for your location.
– California baseline rate: As of 2024, California’s statewide base sales/use tax rate is 7.25% (local districts can add additional rates, making the combined rate higher in many areas). Always check current rates for your locality.
Practical steps — Consumers (checklist)
1. At purchase:
• Check whether the seller charged sales tax. If they did, keep your receipt.
• If the seller didn’t collect sales tax (or you aren’t sure), treat the purchase as potentially subject to use tax.
2. Determine the correct rate:
• Look up your combined state + local sales tax rate on your state tax agency’s website or a reputable aggregator.
3. Calculate use tax:
• Use tax due = purchase price (or taxable portion) × combined rate.
4. Report and pay:
• Many states provide a line on your state income tax return for use tax or a separate use tax return/form. Some allow online payment.
• For large purchases (vehicles, boats), special registration or reporting procedures may apply.
5. Keep documentation:
• Maintain purchase receipts, shipping records, and any correspondence showing the seller did or did not collect tax.
6. When in doubt:
• Contact your state tax authority or a tax professional. Voluntary disclosure can reduce penalties if you owe back tax.
Practical steps — Businesses and sellers (checklist)
1. Determine nexus:
• Review both physical and economic nexus thresholds for the states where you have customers.
• Consider marketplace facilitator laws (many states require online marketplaces to collect and remit tax on behalf of third‑party sellers).
2. Register where required:
• Register for sales tax permits in states where you have nexus.
3. Collect and remit:
• Charge the correct combined rate (state + local) for customer addresses and remit on the required schedule.
4. Maintain records:
• Keep sales invoices, exemption certificates, and filing records for audits.
5. Monitor law changes:
• Sales/use tax law and economic nexus rules continue to evolve; review changes regularly or retain a tax advisor.
Common questions
– Who enforces use tax? State tax agencies enforce use tax; enforcement varies. Some states audit returns or send reminder notices for large purchases.
– Are online purchases taxed? After Wayfair (2018), many remote sellers must collect sales tax on online purchases if they meet economic nexus thresholds. If a seller does not collect tax, the buyer may owe use tax.
– What about exemptions? Some items (groceries, prescription drugs, certain services) may be exempt in your state even if purchased out of state. Confirm exemptions with your state tax agency.
Penalties and interest
– If you fail to report and pay use tax, states commonly assess the unpaid tax plus interest and possibly penalties. The amount and specifics depend on state law and the period involved.
Illustrative calculation
– You buy a $2,000 piece of furniture from an out‑of‑state vendor who did not charge tax. Your local combined rate is 8.5%.
• Use tax due = $2,000 × 0.085 = $170.
The bottom line
Use tax is the consumer‑side counterpart to sales tax. It ensures purchases made without sales tax still contribute to state and local revenues and levels the playing field for in‑state sellers. Consumers should be aware of their obligations, keep records, and pay use tax when required. Businesses should assess nexus, collect tax when obligated, and follow marketplace facilitator rules. For specific filing procedures, rates, exemptions, and penalties, consult your state tax authority or a qualified tax professional.
