2026 Estimated Tax Payment Dates

| April 1–May 31 | June 15, 2026 |
| June 1–August 31 | September 15, 2026 |
| September 1–December 31 | January 15, 2027 |
The IRS confirms these dates in its 2026 estimated-tax guidance.
These payments can be particularly relevant to self-employed individuals, independent contractors, investors, and other taxpayers whose income isn't subject to enough withholding.
Important exception
If you file your 2026 Form 1040 or 1040-SR by the applicable January/early-February 2027 deadline and pay the remaining balance, you may not need to make the January 15 estimated payment.
2026 Business Tax Deadlines

S Corporations
Form 1120-S is generally due on the 15th day of the third month after the end of the corporation's tax year.
C Corporations
Form 1120 is generally due on the 15th day of the fourth month after the end of the corporation's tax year, subject to special rules for certain fiscal and short tax years.

Businesses should also remember that extending the filing deadline does not necessarily eliminate the obligation to pay taxes by the original deadline.

If you miss the IRS tax deadline 2026, you may face interest and penalties depending on whether you failed to file, failed to pay, or underpaid estimated taxes.
Failure to file
A penalty may apply when a required return isn't filed by its applicable deadline or valid extension.

Underpayment of estimated tax
