What Happens if I File After the Deadline?

Reporting your taxes after the respective US tax deadline is still better than not reporting them at all. The IRS emphasizes that the first step to take whenever you realize you’ve missed a deadline is to obtain the necessary files and proceed to submit your tax statements. With the tax deadline extended for many tax categories including federal tax in 2021, it’s also important that you check for any changes to the deadline.

No penalty applies if you don’t owe any taxes. If there is an amount due, though, a penalty calculated as a set percentage is applied to it both for late filing and late payment.
