Maryland's Electronic Filing Program

The Comptroller's Office offers various online services, including the ability to file Maryland tax returns electronically. Electronic filing, also known as e-filing, has saved many millions of taxpayer dollars through reduced processing costs since the 1990's.

E-filing helps you provide your clients with the fastest, safest and most convenient way to file a return. It also provides them with the fastest way to receive their refund if they choose direct deposit and e-file a return. Learn more about electronic filing and how to become a provider below.

For technical assistance, you can also call our eFile Tax Pro hotline at 410-260-7753. You can also submit your technical questions by e-mail at efil@comp.state.md.us.

Personal Resident and Nonresident Returns

Maryland's electronic filing program for personal resident and nonresident returns follows the same rules and guidelines as the IRS electronic filing program, as specified in IRS Publication 1345. We retrieve Maryland tax filings through the federal/state e-file program.

Business Returns

Maryland's electronic filing program follows the same rules and guidelines as the IRS 1120/1065 electronic filing program, as specified in IRS Publication 4164. Returns for the IRS and Maryland can be transmitted to a single point (the IRS). The IRS will forward the Maryland returns to Maryland for processing. Maryland will return acknowledgments back to the IRS where they can be picked up by transmitters. The following links provide information and guidance for software developers and transmitters interested in developing software for the Maryland Fed/State 1120/1065 eFile Program.

Throughout the year, multiple versions of these documents may be used at the same time. It is for this reason that special attention should be paid to the Release Memo issue date and the projected start and end dates.
