Marylandís Software Designations

Effective January 1, 2014, the Comptroller of Maryland began designating e-File Software Vendorsí Maryland products as either Basic or Comprehensive (see Tax Alert). This applies to both business and individual income tax software packages.

The Basic designation is used for simple returns. Software packages designated as Comprehensive support all electronic forms, including Form 500CR, Amended Returns and the transmission of binary attachments (PDFs).

This process is designed to help taxpayers and tax professionals determine which software will best fit their needs. Please see the list of approved eFile software vendors for individuals and businesses
