Quarterly Estimated Tax Due Dates (2026)
If you're self-employed, a freelancer, or receive income without tax withholding, you may need to make quarterly estimated tax payments:
| Quarter | Period Covered | Due Date |
|---|---|---|
| Q1 | Jan 1 – Mar 31 | April 15, 2026 |
| Q2 | Apr 1 – May 31 | June 15, 2026 |
| Q3 | Jun 1 – Aug 31 | September 15, 2026 |
| Q4 | Sep 1 – Dec 31 | January 15, 2027 |
Filing a Tax Extension
If you need more time to prepare your return, file Form 4868 to get an automatic 6-month extension, moving your deadline to October 15, 2026. You can file electronically for free through IRS Free File.
An extension gives you more time to file, not more time to pay. You must still estimate and pay any taxes owed by April 15 to avoid penalties and interest.
What Happens If I File Late?
If you owe taxes and file late (without an extension):
Failure-to-file penalty: 5% of unpaid taxes for each month the return is late, up to 25%. Failure-to-pay penalty: 0.5% of unpaid taxes per month, up to 25%. Interest also accrues on unpaid taxes from the due date.
If you're due a refund:
There is no penalty for filing late if you're owed a refund. However, you have three years from the original due date to claim your refund before it expires.

Yes. The IRS may grant automatic filing and payment extensions to taxpayers in federally declared disaster areas. Check IRS.gov for current disaster relief provisions.
