Unlike India's GST, the US has no single national sales tax. Each state sets its own rate — and many cities and counties add their own on top. This makes US sales tax one of the most confusing systems for newcomers, immigrants, and online shoppers. This guide breaks it all down simply.
Sales tax in the US is a consumption tax added at the point of sale. Unlike GST which is included in the displayed price in many countries, US prices are almost always shown before tax. The tax is added at checkout.
There is no federal sales tax. Instead:
| State | State Rate | Avg. Combined Rate (with local) |
|---|---|---|
| Tennessee | 7.0% | ~9.55% |
| Louisiana | 4.45% | ~9.52% |
| Arkansas | 6.5% | ~9.44% |
| Washington | 6.5% | ~9.38% |
| Alabama | 4.0% | ~9.24% |
| California | 7.25% | ~8.82% |
| Texas | 6.25% | ~8.19% |
| New York | 4.0% | ~8.52% |
| Florida | 6.0% | ~7.02% |
| Oregon | 0% | 0% |
| Montana | 0% | 0% |
| New Hampshire | 0% | 0% |
Every state has different exemptions. Common patterns:
| Item Type | Generally Taxed? |
|---|---|
| Clothing (general) | Yes in most states; exempt in NY, PA, MN |
| Groceries (unprepared food) | Exempt in ~30 states; taxed at reduced rate in others |
| Restaurant food | Taxed in virtually all states |
| Prescription drugs | Exempt in most states |
| Digital downloads (apps, software) | Increasingly taxed; varies widely by state |
| Electronics | Taxed in most states |
| Cars | Taxed in all states (rate varies, often lower) |
Since the 2018 South Dakota v. Wayfair Supreme Court ruling, online retailers are required to collect sales tax in states where they have "economic nexus" — typically $100,000 in sales or 200 transactions per year. This means almost all major online purchases (Amazon, Walmart, etc.) now include sales tax based on your delivery address.
If you run an e-commerce business or freelance service, understanding sales tax nexus is critical. You must collect and remit sales tax in every state where you have nexus (physical presence or economic threshold). Failure to comply can result in large back-tax bills plus penalties. Most small businesses use software like TaxJar or Avalara to automate this.
It depends on the state and the type of service. Most states tax tangible goods. Services are taxed in some states (like Hawaii and New Mexico) but exempt in others. Professional services like legal and medical are generally exempt everywhere.
Unlike VAT refund schemes in Europe, the US does not have a general tourist sales tax refund program. Louisiana is the only state with a limited refund program for international visitors. For most US states, sales tax paid by tourists is non-refundable.
Yes. When you register a privately purchased vehicle, you pay a "use tax" equal to the sales tax rate, calculated on the purchase price or the car's market value (whichever the state uses). This is handled at the DMV during title transfer.
