What is the deadline for filing US federal income taxes this year?

April 15th, just like every year.

Filing Form 4868 gives taxpayers until October 15 to file their 2020 tax return but does not grant an extension of time to pay taxes due. Taxpayers should pay their federal income tax due by May 17, 2021, to avoid interest and penalties. The IRS urges taxpayers who are due a refund to file as soon as possible.

May 17 is the deadline for both filing and paying federal 2020 personal income tax. 

However some state returns are still due April 15 and those generally require you to have already filed a federal return. If you live in one of those states, consider requesting an extension.

Returns for corporations and trusts, and 2021 estimated tax are still due April 15.

May 17th  this year

May 15, it was extended.

May 17th for 2021

Estimated taxes are due April 15.  2020 tax returns AND payment is due on May 17. Your state may have a different deadline.

Any money that is due must be paid by April 15th.

The paperwork is not due until May 17th

May 17....................
