Texas Sales Tax Calculator

What is Texas sales tax?

Texas sales tax is a charge on taxable sales of goods and some services. The state rate is 6.25%. Cities, counties, transit authorities and special districts can add local sales tax, up to a combined local rate of 2%. That makes the maximum combined rate 8.25%.

Your actual rate depends on the sale’s location and whether the item or service is taxable. The calculator works with a combined rate by adding the state rate to the local rate you enter. It can add tax to a price or estimate the tax included in a tax-inclusive total. It does not determine whether a particular sale is taxable or identify the correct local rate for an address.

Why Texas sales tax matters

If you sell taxable goods or services, the tax affects the amount your customer pays and the amount you need to account for. Separating the pre-tax price, state tax and local tax can help you set prices, prepare invoices and reconcile sales records.

If you are buying something, backing tax out of a total helps you understand the pre-tax price and the tax component. That can be useful when checking a receipt or comparing a tax-inclusive amount with a quoted price.

The calculator provides an estimate based on the rate you enter. Check the Comptroller’s rate locator for the exact address, and confirm whether a sale is taxable using the Comptroller’s guidance. For a business tax question that affects your filings, confirm your approach with a qualified tax professional.

How to use this Texas sales tax calculator

1. Enter the amount. For an add-tax calculation, enter the price before sales tax. For a back-out calculation, enter the total that already includes tax.
2. Choose whether to add tax to a price or back tax out of a total.
3. Enter the local tax rate from 0% to 2%. Use the rate for the sale’s location. The calculator combines it with the 6.25% state rate.
4. Review the result. For an add-tax calculation, check the tax to collect and the total. For a back-out calculation, check the estimated pre-tax amount and tax included.

How to read your sales tax result

The combined rate is the state rate plus the local rate you entered. In the example, the 6.25% state rate and 2.00% local rate produce a combined rate of 8.250%. The sales tax to collect is the amount added to the pre-tax price. The total with tax is what the customer pays when tax is added.

When you back tax out, the calculator divides the tax-inclusive total by one plus the combined rate. The result separates the estimated pre-tax amount from the tax already included. Check that the entered local rate matches the sale’s location before relying on the result.

How to use your result in pricing and bookkeeping

1. 01

   Keep the tax separate from your price

   Show the pre-tax price and sales tax as separate amounts on quotes, invoices and receipts when appropriate. This makes it easier to explain the customer’s total and reconcile the sale in your records.

2. 02

   Verify the location rate

   Before setting up prices or invoices, check the Comptroller’s rate locator for the exact address. If you sell in more than one location, review each location rather than applying one local rate to every sale.

3. 03

   Review which sales are taxable

   Do not assume every product or service is treated the same way. The Comptroller identifies some taxable services, including data processing, repair and certain cleaning services. Check the applicable guidance for what you sell.

4. 04

   Reconcile totals with your records

   Compare tax collected with your sales records and receipts. If a total includes tax, use the back-out calculation to separate the estimated tax from the pre-tax amount, then confirm the rate and tax treatment.

Common Texas sales tax mistakes

• Entering the wrong local rate

  The local rate can vary by location. Using an incorrect rate changes both the calculated tax and the customer’s total. Verify the address-specific rate rather than assuming the maximum applies everywhere.

• Choosing the wrong calculation

  Choose add tax when your amount is before tax. Choose back out when your amount already includes tax. Selecting the wrong option can lead you to quote or record the wrong pre-tax amount.

• Treating every sale as taxable

  The calculator applies a rate to an amount; it does not decide whether the sale is taxable. Check the Comptroller’s guidance for the specific product or service.

• Using an estimate as a filing determination

  The result depends on the amount and rate you enter. Confirm the location, taxability and reporting treatment before using it for business filings. Ask a qualified tax professional if you need help applying the rules to your situation.
