About Sales Tax Calculator
Calculates the sales tax on a purchase and the total price including tax, based on a tax rate you enter — built around the US model, where sales tax is a single rate added at checkout (combining state, county, and city rates).
Pick your state to fill in its average combined rate (or its state-only base rate), or type your exact local rate. A ZIP code finds your state and fills the rate only where the state has a single rate; otherwise it asks you to look up your address. Enter the price, quantity and any discount, or tick Several items to mark each item taxable or exempt and add shipping.
Sales tax rates vary by state, county, and sometimes city — look up your specific local combined rate rather than assuming a single statewide number, since the actual rate at checkout is often higher than the state rate alone. Looking for India's GST specifically? It works differently (split into CGST/SGST components rather than a single added rate) — the GST Calculator tool handles that correctly instead of approximating it here.

- Does this account for different tax rates within the same state or country?
- It's built around the general rate structure for the region you select, but local jurisdictions can layer on their own additional rates. Confirm the specific combined rate for your exact location before relying on it for anything official.
- How do I calculate sales tax backwards?
- Choose Remove Sales Tax and enter the price that already includes tax. The tool divides by 1 plus the rate to find the price before tax, and the tax is the difference. For example, $108 with 8% tax is $100 before tax and $8 of tax.
- What is the sales tax in my state?
- Pick your state to fill in its average combined rate or its state-only base rate from the Tax Foundation midyear 2026 table (rates as of 1 July 2026). Your own rate can be higher or lower because cities, counties and districts add their own, so check your exact rate with your state's revenue department.
- Is sales tax charged on shipping?
- It depends on the state and on how the shipping is billed. Some states tax shipping when the item is taxable and others do not. In the several-items view you tick whether shipping is taxable, so you decide; check your state's revenue department for its rule.
- Why do rates differ within a ZIP code?
- A ZIP code is a mail route, not a tax area. One ZIP can cross city, county and special-district lines, and each can add its own tax. That is why the ZIP box fills in a rate only where the state has a single rate, and otherwise asks you to look up your street address with your state's official page.
