Taxpayers who need extra time to file an extension on their taxes have one day left to avoid the cutoff date.

The IRS explains on its website that taxpayers who asked for an extension by the April 15 tax filing due date have until Wednesday, Oct. 15 to file without penalties, even as the government shutdown enters its second week.

FOX Business reported that while extensions give taxpayers more time to file, they don't receive additional time to pay what they owe and must pay taxes due on April 15 of this year to avoid being impacted by penalties and interest.

The IRS furloughed half of its workforce this month because of the government shutdown, but the agency established a shutdown contingency plan to keep some customer service agents at work.

And these individuals are listed below:

However, tax payments are still due April 15, or interest will be charged. Details are available in Publication 3, Armed Forces’ Tax Guide.
The IRS noted that those serving in combat zones have about 180 days after they leave the combat zone to file tax returns and pay any taxes due.

This year they have until June 16 to file. However, tax payments are still due April 15, or interest will be charged, according to the IRS.
Taxpayers in certain federally declared disaster areas may also have an automatic extension to both file and pay. According to the IRS, taxpayers in these areas are not required to submit an extension request. Information on the most recent tax relief for disaster situations is available on IRS.gov.
