Tax Day is the deadline to file or e-file your federal income tax return (and most state tax returns).

Exceptions for certain states: Maine and Massachusetts state taxes are due April 17; Delaware and Iowa state taxes are due April 30; Hawaii state taxes are due April 20; Virginia state taxes are due May 1; and Louisiana state taxes are due May 15.

This is also the deadline to request an extension by filing Form 4868 and to pay any taxes due from tax year 2023 (even if you are requesting an extension).

You must also make HSA and IRA contributions for tax year 2023 by April 15, 2024.

April 15 is also when estimated tax payments are due for the first quarter of 2024.
