Frequently Asked Questions

Not if you’re certain you stayed within the same local taxing jurisdiction. If you aren’t sure, enter both locations. Many ZIP codes have more than one local taxing jurisdiction.

If you changed your city or county of residence (even within the same ZIP code), then enter your new residence separately in the calculator. The calculator will give the correct answer whether or not the two locations have different sales tax rates.

No. But the calculator has local sales tax rate information. This is not contained in the paper instructions. It also does the math for you.

Because it is in lieu of your having to add all of your general sales tax payments from your receipts, which you are always entitled to do.

These “big ticket” items are generally not purchased every year. If an average annual amount were included in the tables for these purchases, then taxpayers would be able to get double benefit for them: using their actual receipts in years when they purchased such items, but using the tables in all other years. As a result, the law provides for such items to be accounted for outside of the tables entirely.

There are two key features of a general sales tax: What is taxed (the tax base), and how much it is taxed (the tax rate). Among states that have local sales taxes, these two features create three basic categories:

  1. When the local tax base is the same as the state tax base and there is just one local sales tax rate throughout the state – The local sales tax amount can be included with the state table using a combined rate on the same items.
  2. When the local tax base is the same as the state tax base, but the local sales tax rates vary throughout the state - The local sales tax amount can be derived from the state amount using the ratio of the local rate to the state rate.
  3. When both the local tax bases and the local sales tax rates vary throughout the state - The local sales tax amount must be derived independently from the state amount.

The deduction for state and local general sales tax is meant to be the amount of sales tax you actually paid. Rather than require you to keep all of your receipts, the tax law allows you to use the optional sales tax tables provided by the IRS. This lets you approximate your sales tax payments using average consumption patterns, taking into account the relevant tax rates and your income and family size.

If a locality (defined as a state-county-ZIP code combination) has more than one taxing district, the calculator uses the average of the local sales tax rates among those districts to estimate the amount of sales tax the average taxpayer in that locality actually paid. This assumes residents purchase taxable items throughout the locality, not just in the taxing jurisdiction where they reside.

  • For example: If there are two tax districts within a locality, with local tax rates of 1% and 2%, then the calculator uses 1.5%, which is the average of the two local tax rates. The average provides a much more accurate estimate of the sales tax actually paid by taxpayers in localities with multiple taxing districts.

Yes. The Sales Tax Deduction Calculator is updated with overseas U.S. military zone and districts where members of U.S. military pay no sales tax. If you are deployed overseas, you can use the calculator to determine the sales tax you paid while you were in the United States.

When you use the calculator, enter one of these military zone abbreviations:

  • AA - Military personnel in the Americas, excluding Canada
  • AE - Military personnel in Europe, Middle East, Africa and Canada
  • AP - Military personnel in Asia Pacific
  • APO - Military Post Office for U.S. Army & Air Force personnel
  • FPO - Military Post Office for U.S. Navy personnel
  • DPO - Post Office for U.S. Embassy, State Department and other diplomatic personnel
