People directly affected by the storm that hit the Northeast on Sunday and Monday are entitled to a two-day extension for filing their tax returns, the Internal Revenue Service said Monday.

Impacted taxpayers will have until midnight Thursday, April 19, to file their taxes. For others, the deadline this year is April 17 because April 15, normally tax day, fell on a Sunday and Monday was Emancipation Day, a legal holiday in Washington D.C.

"Because this unusually forceful storm hit within 24 hours of the filing deadline, we are giving affected taxpayers 48 additional hours," IRS Commissioner Mark Everson said in a statement.

The deadline extension is aimed at helping those directly affected by power outages or public transportation problems such as flight cancellations that made it difficult for people to file their returns on time.

Affected taxpayers, in order to avoid incurring late fees, should mark their paper tax returns with the words "April 16 Storm," the IRS said. Those filing electronically can use their software's "disaster" feature if available.
