Frequently Asked Questions

It uses the state's base (statutory) rate and lets you add your local city or county rate. Combined rates vary by address, so check your local rate for an exact figure.
Which states have no sales tax?expand_more
Alaska, Delaware, Montana, New Hampshire, and Oregon have no statewide sales tax. Alaska and Montana can still have local sales taxes in some areas.
Is sales tax based on where I live or where I buy?expand_more
US sales tax is generally based on the location where the sale takes place or where the item is delivered (destination-based in most states).
What this calculator does
Work out sales tax and the total price from a pre-tax amount, using your state's base sales-tax rate plus any local city or county rate.
Who it is for
Shoppers, freelancers, and small businesses who need to estimate sales tax on a purchase or invoice in a US state.
How it works
The combined rate is your state's base rate plus any local rate you enter. Sales tax is the pre-tax amount multiplied by that combined rate, and the total is the amount plus the tax.
Example calculation
On a 100 purchase in California (7.25% state rate) with no local rate, sales tax is 7.25 and the total is 107.25. Add a 2% local rate in Texas (6.25% state) and the combined rate is 8.25%, so a 200 purchase has 16.50 tax and a 216.50 total.
Regional variations
Five states have no statewide sales tax. Elsewhere, local rates can add several percentage points, and some categories (groceries, clothing, prescriptions) are taxed differently or exempt.
Common mistakes to avoid
- Assuming the state rate is the full rate - many cities and counties add their own local sales tax.
- Applying sales tax to items that are exempt in your state, such as some groceries or clothing.
- Using your home rate for an online order delivered to a different state.
