Online Verification of Maryland Tax Account Numbers

Businesses are often confronted with customers who wish to make purchases tax free, either because they intend to resell the item and charge the sales tax or because they are making a purchase for an organization possessing a tax exempt card issued by the State Comptroller's Office.

Other individuals may fall under the Diplomatic Tax Exemption Program, which provides sales and use, occupancy, food, airline, gas, and utility tax exemptions to eligible foreign officials on assignment in the United States.

Using the online search, you can verify that the customer possesses a valid tax exempt number or a valid Maryland combined registration number. You can also print out a prepared resale certificate for your records if the purchase is being made for resale.

You may use this page before you complete a sales transaction to verify:

• a Maryland Tax Registration Number, or
• a Maryland Sales and Use Tax Exemption Number

Verification of a Diplomatic Tax Exemption card is available through the tax card verification database of the U.S Department of State.
