When Are Taxes Due in 2026? Tax Deadlines by Month
Avoid costly IRS penalties and interest by tracking the most important 2026 federal income tax due dates for individual taxpayers.
Rocky Mengle
Although the April 15 tax deadline has passed, federal tax obligations extend well beyond the traditional spring filing window.
In fact, the IRS enforces a year-round monthly schedule of deadlines for estimated quarterly payments, extension requests, tip reporting, and specialized account contributions.
Missing certain individual dates could trigger immediate penalties. The standard penalty for failing to file an on-time return is 5% of the unpaid tax per month (or partial month), while late payments accrue an additional 0.5% monthly fee up to a 25% cap, plus interest.

However, it can be hard to keep track of every IRS tax deadline and pay your taxes on time. (There's at least one tax deadline every month, after all.)
So to make things easier, here are the most important 2026 federal income tax due dates for individuals.
January
January tax deadlines
Date | Deadline |
January 12 | Tips for December 2025 reported to employer |
January 15 | Estimated tax payment for fourth quarter of 2025 |
January 15 | Farmers and fishermen paid estimated tax for 2025 |
January marked the start of the 2026 tax filing season, but there were also a few tax deadlines during the month. The first was related to tips, which must have been reported to your employer by the 10th of the month following the month you received them.
The other January tax deadline involved estimated tax payments for the last quarter of 2025, which were due January 15 for most people who were required to make quarterly payments. You didn't need to make this payment if you filed and paid your taxes in full by February 2, 2026 (normally the end of January, but January 31 fell on a weekend).
If you lived in one of the states with extended IRS tax deadlines due to natural disasters, your January estimated tax payment (and other relevant tax obligations) could have been paid in accordance with that new deadline.
February
February tax deadlines
Date | Deadline |
February 2 | Deadline to file and pay 2025 taxes in full if you didn't make an estimated tax payment in January |
February 10 | Tips for January 2026 reported to employer |
February 16 | Form W-4 filed to reclaim exemption from withholding for 2026 |
The monthly tip reporting deadline was February 10. This time, the deadline was for taxable tips received in January.
If you were exempt from income tax withholding in 2025 and wanted to reclaim the exemption for 2026, you needed to fill out a new W-4 form and give it to your employer by the 16th (if you qualified for the exemption). The typical deadline for filing and paying your estimated taxes in full was February 2 this year, due to January 31 falling on a weekend.
March
March tax deadlines
Date | Deadline |
March 2 | Farmers and fishermen filed 2025 tax return to avoid penalty if estimated tax not paid by January |
March 10 | Tips for February 2026 reported to employer |
March 16 | S-Corporations and partnerships filed 2025 business tax returns |
There were only three tax deadlines in March: Farmers and fishermen who didn't make an estimated tax payment in January; S-Corporations and partnerships; and monthly tip reporting.
April
April tax deadlines
Date | Deadline |
April 1 | First required minimum distribution (RMD) by individuals who turned 73 in 2025 |
April 10 | Tips for March 2026 reported to employer |
April 15 | 2025 tax return and tax payment due |
April 15 | Form 4868 filed to request six-month income tax return filing extension (payment of tax not extended) |
April 15 | Schedule H (1040) filed and paid employment taxes for household employees (filed separately if Form 1040 was not filed) |
April 15 | Estimated tax payment for first quarter of 2026 |
April 15 | Contributions to individual retirement account (IRA) for 2025 |
April 15 | Withdrawals of excess IRA contributions in 2025 to avoid penalty if filing of form 1040 was not extended |
April 15 | Contributions to health savings account (HSA) for 2025 |
April 15 | Contributions to solo 401(k) plan or simplified employee pension (SEP) plan for 2025 by self-employed if filing of form 1040 was not extended |
April 15 | Filed 2022 tax return (Form 1040) to request unclaimed tax refund for the 2022 tax year |
April was an important month for tax deadlines.
For most people, April 15 was the last day to file a 2025 tax return, unless you applied for an automatic six-month tax extension with the IRS, which was also due on April 15.
If you were a household worker (for example, a nanny), you also had until April 15 to file Schedule H and pay your employment taxes.
- April 15 was also the last day that you could contribute to an IRA or health savings account (HSA) for 2025.
- In addition, except for those who requested an extension to file their 2025 tax return, April 15 was the deadline for self-employed people to contribute to a solo 401(k) or a simplified employee pension (SEP) plan for 2025.
- If you made excess IRA contributions in 2025, these must have also been withdrawn by April 15.
After you turn 73, you must take your first required minimum distribution (RMD) from your traditional IRAs and 401(k) plans by April 1 of the following year. RMDs for inherited IRAs have their own set of rules.
May
May tax deadlines
Date | Deadline |
May 11 | Tips for April 2026 reported to employer (Form 4070) |
May 15 | Deadline for certain tax-exempt organizations on a calendar-year basis to file Form 990 series. |
You only needed to worry about two May tax deadlines: Tax-exempt organizations that did not file for an automatic six-month extension (taxes still needed to be paid by the original due date), and tips you received in April.
However, if you received less than $20 in tips from a single employer in April, you didn't need to worry about this deadline.
June
June tax deadlines
Date | Deadline |
June 10 | Tips for May 2026 reported to employer |
June 15 | Estimated tax payment for 2nd quarter of 2026 |
June 15 | U.S. taxpayers living and working abroad filed 2025 tax return |
June 15 | U.S. taxpayers living and working abroad filed Form 4868 to request four-month income tax return filing extension (payment of tax not extended) |
June 15 | Military personnel on duty outside the U.S. filed 2025 tax return |
June 15 | Military personnel on duty outside the U.S. filed Form 4868 to request four-month income tax return filing extension (payment of tax not extended) |
Military personnel and other taxpayers serving or living outside the U.S. had until June 15 to file their 2025 tax returns. Estimated tax payments for the second quarter of 2026 were also due June 15.
July

August

Estimated tax payments for the third quarter of 2026 are due by September 15.
October
October tax deadlines

October 12 | Tips for September 2026 reported to employer |
October 15 | File extended 2025 tax return (Form 1040) |
October 15 | Withdraw excess IRA contributions in 2025 to avoid penalty if filing of Form 1040 was extended |
October 15 | Contribute to solo 401(k) plan or simplified employee pension (SEP) plan for 2025 by self-employed if you received a filing extension |
Most October deadlines only apply if you receive a six-month tax filing extension. If that applies to you, you have to meet the October 15 deadline to avoid penalties.
Some taxpayers who receive a filing extension could also contribute to or withdraw from certain accounts.
See the table above to determine if that applies to you.
November
