IRS Confirms Taxpayers Must Meet the Final October 15 Cutoff—Shutdown Does Not Change Federal Liability.
The deadline is here for millions of Americans who requested a filing extension earlier this year. Tax returns must be submitted by the mandatory deadline of October 15, a critical requirement that remains in full effect even with the ongoing U.S. government shutdown.
The Internal Revenue Service (IRS) is clear: A lack of funding does not relieve taxpayers of their federal income tax responsibilities.
“Taxpayers should continue to file, deposit and pay federal income taxes as they normally would,” an IRS spokesman confirmed to CBS News.
The Oct. 15 Clock and Why It Matters
Roughly 20 million Americans—about 13% of all taxpayers—request this six-month filing extension annually. While the extension is automatically granted upon request, giving taxpayers extra time to sort out complex financials, it is vital to remember its limitation:
An extension only grants more time to file, not more time to pay. The IRS expects any taxes owed to have been paid by the regular April 15 deadline to prevent penalties.
How the Shutdown Impacts the IRS
While the government shutdown has shuttered most IRS offices, key operations remain active to handle the flood of incoming returns.
According to tax advisory firm Baker Tilly, approximately half of the agency’s workforce is currently furloughed. However, essential personnel are on the job in critical areas like taxpayer services and submission processing, ensuring the agency is ready to process the millions of returns due today.
The Final Cutoff Time
The filing deadline for those with an extension is 11:59 p.m. on October 15 in the taxpayer’s local time zone. Taxpayers submitting electronically must ensure their return is successfully received by the IRS before this midnight cutoff.
Limited Exceptions: Natural Disaster Relief
The October 15 date is generally a hard deadline, and the IRS does not grant further extensions to the general public.
However, the agency has offered relief to specific areas hit hard by recent natural disasters. Taxpayers in designated disaster zones have been granted temporary filing extensions beyond today’s date:
- Arkansas and Tennessee: Residents affected by April storms, flooding, and tornadoes have until November 3 to submit their federal returns.
- Kentucky and West Virginia: Certain counties in these states, impacted by February storms, also have an extension until November 3.
Penalties for Missing the Deadline
Failure to submit your tax return by the October 15 deadline can lead to significant financial penalties:
- Penalty Fee: The IRS charges a penalty of 5% of the unpaid taxes for each month or partial month the return is late, up to a maximum of 25%.
- Waiver Opportunity: The IRS might waive this penalty if a taxpayer can provide a “reasonable explanation” for the late filing. Anyone requesting a waiver must attach a detailed, written explanation to their tax return.
- Refunds: If you are due a refund and file late, the IRS typically does not impose a penalty.
