The first quarterly payment is due for individuals who must make estimated tax payments using Form 1040-ES.

Deadline for filing and paying your 2020 income tax return.  This is also the deadline for requesting an automatic six-month extension to file your income taxes with Form 4868. Remember, however, that this is only an extension for filing: You must still pay any tax due on time.

Deadline for filing for U.S. Citizens or resident aliens living and/or working outside the United States and Puerto Rico. File Form 1040 and pay any tax, interest, and penalties due. If you want additional time to file your return, file Form 4868 to obtain a four month extension to file.

The second quarterly payment is due for individuals who must make estimated tax payments using Form 1040-ES.

The third quarterly payment is due for individuals who must make estimated tax payments using Form 1040-ES.

Income tax filing deadline for taxpayers who requested a six-month extension to file their returns. Returns are still filed with Forms 1040, 1040A or 1040EZ.

Last day to e-file your 2019 tax return. After this date, the IRS will no longer accept 2019 returns electronically, and you will need to paper file your return.

Deadline to claim a refund for a 2020 Amended Tax return. You generally have a deadline of 3 years from the original due date to claim a tax refund, if you wait longer than 3yrs any tax refund is lost.  On the other hand, you can file an Amended Return to pay taxes due anytime, since taxes owed are never forgiven.

You can file a Tax Return for a previous tax year anytime, but you can only claim a refund within 3 years of the original tax deadline. This can only be prepared and filed via mail, however.
