The IRS is granting many of the businesses affected by this week’s Winter Storm Stella additional time to request a six-month extension to file their 2016 federal income returns.

The relief is offered to victims and tax professionals affected by the storm that hit portions of the Northeast and Mid-Atlantic.

Business taxpayers who were unable to file their tax returns by the March 15 due date can request an automatic extension by filing Form 7004 on or before March 20.

Form 7004 provides a six-month extension for returns filed by partnerships (Forms 1065 and 1065B) and S corporations (Forms 1120S).

Eligible taxpayers should write “Winter Storm Stella” on their Form 7004 extension request (if filing Form 7004 by paper).
