Tax Preparers Online Services

The Revenue Administration Division of the Comptroller of Maryland has introduced a Preparer Services site. This interactive service currently allows the tax preparer to view the client’s Form 1099-G information, and has the following features:

  • Each tax preparer must register in order to use the site, using a valid PTIN number and their federal adjusted gross income (FAGI) from the prior year’s Maryland tax return.
  • Preparers who did not file a Maryland tax return in the prior year will need to submit certain required documentation to the Revenue Administration Division, who will then validate them and issue a PIN. Please contact the Tax Practitioner Hotline at 410-260-7424 Monday through Friday from 8:30a.m. until 4:30p.m. or by e-mail to
  • The client (taxpayer) will separately need to log onto the site and authorize the tax preparer to view their Form 1099-G record. The client must have an enhanced registration.
  • Preparers will identify the client whose information they wish to access, providing the SSN and entire last name of the client. Both must match, and the client must have authorized that preparer to access his/her information.
  • Taxpayers have the ability to view a history of tax preparer activity in their account
  • Taxpayers have the ability to grant or revoke preparer access to their account. As the online services are expanded, the taxpayer will have the ability to grant or revoke specific capabilities of the site.

Go to the Tax Preparer's Online Service Center.

Once you've had a chance to use our interactive online services, please take a few moments to let us know what you think!
