# Sales Tax Calculator

Leave one field blank and it solves for before-tax price, tax rate, or the final total. See the tax amount, the step-by-step math, and a visual breakdown, then check typical U.S. state rates in the guide below.

## How to use this sales tax calculator

1. Enter the before-tax price and tax rate to find the total, and leave after-tax blank.
2. If you already know the receipt total, enter the after-tax price and rate to back out the pre-tax amount instead.
3. Shopping across jurisdictions? Enter both prices and the calculator works out the effective rate that was actually applied.

## What is sales tax?

Sales tax is a consumption levy added right at the point of sale. In the United States, states and localities administer it, so the rate printed on a receipt can combine state, county, city, and special-district pieces all at once. Unlike VAT, U.S. sales tax usually shows up as its own line on the receipt instead of being baked into the shelf price.

### Forward and reverse formulas

If you already know the final total, you can work backward instead:

### Sample U.S. state rates

Five states skip a statewide sales tax entirely: Alaska, Delaware, Montana, New Hampshire, and Oregon, though local taxes can still sneak in depending on the area. The table below shows a cross-section of state rates alongside approximate combined local maximums:

Check current figures with your state revenue department before you file or price anything.*

### Sales tax vs VAT vs GST

**Value-added tax (VAT)** shows up across Europe and plenty of other regions. It gets assessed at each stage of production, but the consumer still ends up carrying the cost. **Goods and services tax (GST)**, used in countries like Canada, Australia, and India, works on a similar credit-invoice model. U.S. sales tax is simpler at the register, but the rate can swing sharply from one ZIP code to the next.

### Tax deductions (U.S.)

If you itemize, you can deduct either state and local sales tax *or* income tax, subject to SALT caps and IRS rules. Hang onto receipts for big purchases if you go with the sales-tax method. This calculator is meant for estimation. Talk to a tax professional before you make a filing decision.

## Examples and use cases

### Worked example

Take a $200 item in a jurisdiction with 8.25% combined sales tax:

- Tax amount = $200 × 0.0825 = $16.50
- Total at register = $216.50
- Reverse check: $216.50 ÷ 1.0825 = $200 pre-tax

### Real-world use cases

- Cross-border shopping: A buyer near a state line compares receipts to see if driving to a lower-tax county actually saves enough on a big appliance purchase.
- Small business pricing: An Etsy seller adds the correct combined local rate to handmade goods so the shelf price matches what the customer actually pays at checkout.
- Expense reporting: An employee enters the after-tax total from a receipt and backs out the pre-tax amount for a reimbursement form that excludes tax.

## Frequently Asked Questions

### How do I find the price before tax from a receipt?
Enter the **after-tax total** and the **tax rate**, leave before-tax blank, and the calculator divides by (1 + rate) to get there.

### Does this include local city tax?
Enter whatever **combined rate** you actually pay: state plus county or city, if that applies to you. The reference table shows approximate maximums once local add-ons are included.

### What does the pie chart show?
Blue is the pre-tax subtotal, green is the tax portion of your after-tax total.

### Can I calculate tax from only two known values?
Yes. Enter any two of before-tax price, tax rate, or after-tax total, and the calculator solves for whichever one is missing, refreshing the breakdown as it goes.

### Are the listed state rates official?
No, they are approximate reference rates meant for planning. Always confirm the current combined rate with your state or local tax authority before you file or quote prices.
