April 15 is the deadline for filing individual tax returns with the Internal Revenue Service for previous calendar year.
Individual Tax Returns Due for last year: If you haven’t applied for an extension, e-file or postmark your individual tax returns by midnight on April 15.
Individual Tax Return Extension Form Due for last year: If you need more time to prepare your tax return, you can file for an extension to push your deadline back to October 15.
1st Quarter Estimated Tax Payment Due: If you are self-employed or have other first-quarter income that requires you to pay quarterly estimated taxes, get your Form 1040-ES postmarked by April 15 tax deadline.
Last Day to make a prior year IRA Contribution: If you haven’t already funded your retirement account, do so by April 15. This is the deadline to contribute to a traditional IRA, deductible or now, and a Roth IRA. If you have a Keogh or SEP and you get a filing extension to October 15, then you can wait until then to put money into those accounts.
