Sales Tax Calculator by ZIP

Calculate sales tax with less guesswork. Sales Tax Calculator by ZIP helps you look up US sales tax rates, estimate tax on a purchase, and see the total before you pay. Search by ZIP code, city, or state, enter an amount, and get a clear calculation in seconds.

Use it to check a purchase, compare prices across states, prepare a quote, or review a receipt. Built for shoppers, freelancers, and small businesses.

FIND SALES TAX RATES BY LOCATION

Choose the United States, browse states and cities, or search a ZIP code to find the relevant location. Select a state for its statewide rate or choose a city to work with a combined sales tax rate. Location details can show the state sales tax, county tax, city tax, and local district tax components available for that location.

See how a combined rate is formed instead of one unexplained percentage.

CALCULATE BEFORE OR AFTER TAX

Enter a purchase amount and choose the calculation you need:

- Before Tax adds sales tax to the entered price and shows the final total.
- After Tax works backward from a tax-inclusive total to estimate the subtotal and tax amount.

Results are separated into subtotal, calculated tax, and total amount, so you can review each part at a glance. Change the location or amount whenever you want to compare another result.

APPLY A DISCOUNT

Turn on the discount option, enter a percentage, and let the calculator apply the discount before calculating sales tax. This is useful when checking sale prices, promotional discounts, or marked-down items. The result shows the discounted subtotal, the calculated tax, and the amount due.

SAVE LOCATIONS YOU USE OFTEN

Add frequently used countries, states, provinces, or cities to Favorites. Saved locations give you a shorter route back to the tax rates you check most often. Apply a favorite to the calculator instead of repeating the full location search each time.

REVISIT RECENT CALCULATIONS

Calculation History keeps recent results inside the app. Review the amount, discount, location, rate, subtotal, tax, and total. Restore a result to adjust it or run a similar calculation. Remove individual items or clear the full history.

CHOOSE YOUR DISPLAY CURRENCY

Set the amount display to US Dollar, Canadian Dollar, Euro, or British Pound. The selected currency changes how purchase amounts and results are formatted while the tax calculation continues to use the rate for the location you selected.

DESIGNED FOR QUICK CHECKS

The focused layout keeps the amount, location, tax breakdown, discount, and result on one screen. Move between the calculator, tax rate search, Favorites, and Settings without building formulas or repeatedly entering rates.
