Business tax e-File

Business Tax Services

The electronic filing program that New York City participates in (known as Modernized e-File or MeF), is hosted by the IRS. All participating jurisdictions, including NYC, obtain their returns through the IRS-maintained MeF gateway. Once received by the IRS, returns remain in the gateway until the taxing jurisdictions retrieve them. The IRS has marked these returns with an electronic received date, which is the date the Department of Finance will use to determine the timely filing of these returns for New York City purposes.

Note: New York City will accept—and strongly prefers—that electronically filed returns be amended electronically as well. At present, we accept amended returns through our MeF program for tax years 2022, 2023, and 2024.

The Department of Finance participates in four of the IRS Federal and State Modernized e-File programs, which allow New York City corporations, businesses, and individuals to electronically file their Federal and NYC business tax returns together: 1120, 1065, 1040, and 1041.
