The Internal Revenue Service has extended the deadline to file taxes until midnight April 18, following a system outage Tuesday morning.
The Indiana Department of Revenue announced it will also extend its deadline.
People attempting to file their taxes electronically were still able to on Tuesday, but those making payments weren't able for most of the day.
“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 in a statement.
Taxpayers who need an extension beyond midnight can find more information at the Indiana Department of Revenue's website or on the IRS website.
