Quick answer. Add tax: total = price × (1 + rate). Remove tax: pre-tax = total ÷ (1 + rate). Example: $40 at Texas 6.25% → tax $2.50, total $42.50. Rates below are statewide base rates as of 1 January 2026 — local city/county tax is often extra.
How to use the sales tax calculator
- Pick a mode. Add tax to a pre-tax price, strip tax out of a receipt total, or show the tax amount only.
- Enter the price and choose a US state (or DC). The statewide base rate fills in automatically.
- Optional custom rate. Tick the box and type a combined local rate when you know the ZIP-level figure.
Formulas
- Add tax: tax = price × rate%, total = price + tax.
- Remove tax: pre-tax = total ÷ (1 + rate%), tax = total − pre-tax.
- Tax only: tax = price × rate%.
Worked examples
| Pre-tax | State (base rate) | Tax | Total |
|---|---|---|---|
| $40.00 | Texas (6.25%) | $2.50 | $42.50 |
| $100.00 | California (7.25%) | $7.25 | $107.25 |
| $25.00 | New York (4.00% state) | $1.00 | $26.00 |
| $60.00 | Oregon (0%) | $0.00 | $60.00 |
New York City buyers usually pay more than 4% because of local tax — use a custom rate for combined figures.

Frequently asked questions
Are these the full tax rates I will pay at checkout?
No. The built-in figures are approximate statewide base rates. Many cities and counties add local sales tax on top. Use a custom rate when you know the combined rate for a ZIP code.
Which states have no statewide sales tax?
Alaska, Delaware, Montana, New Hampshire and Oregon have no statewide sales tax. Alaska still allows local sales taxes in some communities.
How do I add sales tax to a price?
Total = price × (1 + rate). Example: $40 with 6.25% tax is 40 × 1.0625 = $42.50.
How do I remove sales tax from a total?
Pre-tax price = total ÷ (1 + rate). Example: $42.50 at 6.25% is 42.50 ÷ 1.0625 = $40.00.
Do online sellers always charge sales tax?
It depends on nexus rules for your business and the marketplace. Etsy, Shopify and eBay often collect and remit in many states for you — check your seller dashboard.
