Waited till the last minute to file your taxes? You’re in luck because the IRS is extending the deadline to April 18.

On the night of Tax Day (April 17) the US Internal Revenue Service’s website crashed and was unavailable for most of the day. They later came out to announce that they’ll be giving taxpayers an extra day to file and pay their federal taxes.

Last minute taxpayers now have till 11:59 pm on April 18, to submit their returns electronically through the IRS website or third-party softwares.

The IRS apologized for the issue and said it appreciated everyones patience. “This is the busiest tax day of the year, and the IRS apologizes for the inconvenience this system issue caused for taxpayers,” said acting IRS Commissioner David Kautter said in a statement.

Citizens were already has an extended deadline to submit their taxes this year. Usually the deadline is April 15 but it fell on a Sunday and the next day was Emancipation Day, a legal holiday in Washington DC to commemorate the signing of the Compensated Emancipation Act in 1863.
