When Can I File Taxes? 2026 Filing Season Dates & Deadlines

Quick answer: For tax year 2025, IRS e-file opened Monday, January 26, 2026, the filing and payment deadline was Wednesday, April 15, 2026, and the extension deadline is October 15, 2026. For tax year 2026, the projected federal deadline is Thursday, April 15, 2027, with a projected extension deadline of Friday, October 15, 2027.

2026 Filing Season: Key Dates Timeline

Every date below comes from an official IRS source. Dates marked Projected follow the standing IRS April 15 and 6-month extension rules and will be confirmed when the IRS announces the 2027 season.

When Can I Start Filing?

Quick answer: You can start filing once the IRS opens e-file and you have every income document. For tax year 2025, the IRS began accepting and processing federal individual returns on Monday, January 26, 2026, and the IRS Free File program opened earlier on January 9, 2026 for qualified taxpayers.

Do not file until every document has arrived. Wait for all of these before you submit:

• Form W-2 from each employer (wages and withholding).
• Forms 1099 — interest, dividends, freelance and contract income, retirement distributions, and unemployment.
• Form 1095-A if anyone on the return had marketplace health coverage.
• Records for deductions and credits you plan to claim, such as student loan interest, IRA contributions, and childcare expenses — see the Earned Income Tax Credit guide if you have lower earned income.

Filing with missing forms is the most common cause of rejected returns and delayed refunds. If you are ready early, you can also use free filing options or follow our step-by-step how to file taxes guide.

Filing Deadline and What Counts as On Time

Quick answer: For tax year 2025, the federal filing and payment deadline was Wednesday, April 15, 2026. Your return counts as on time if the IRS accepts your e-filed return by midnight on April 15, or if a paper return is postmarked by April 15.

The IRS applies a weekend and holiday rule: if April 15 falls on a Saturday, Sunday, or legal holiday, the deadline moves to the next business day. That shift was not needed in 2026, and April 15, 2027 is a Thursday, so the projected tax year 2026 deadline of Thursday, April 15, 2027 is not expected to move. See also our tax filing deadline 2026 guide.

April 15 is both the filing deadline and the payment deadline. Even if you get an extension to file, any tax you owe is still due in April — pay what you can to limit penalties and interest.

Quarterly Estimated Tax Dates (2026)

Quick answer: Self-employed and gig workers pay 2026 estimated tax on April 15, June 15, and September 15, 2026, with the final Q4 2026 payment due January 15, 2027.

*You do not have to make the payment due January 15, 2027, if you file your 2026 tax return by February 1, 2027, and pay the entire balance due with your return. Calendar-year farmers and fishermen have a special rule: pay 2026 estimated tax by January 15, 2027, or file and pay in full by March 1, 2027. For worksheets and safe-harbor rules, see our estimated tax payments guide.

State Deadlines Note

Quick answer: Most states mirror the federal April 15 deadline, but several set their own dates for 2026. Confirm with your state revenue department before you file.

State dates change yearly and state extension and payment rules may differ from IRS rules — always confirm with your state revenue department. Compare rates in our state tax rates guide.

Refund Timing: How Long After You File?

Quick answer: E-file with direct deposit and the IRS issues more than nine out of ten refunds in less than 21 days. Paper returns take six weeks or longer.

• E-filed return: refund typically in less than 21 days (about 3 weeks from the e-file date).
• Paper return: six or more weeks from the mailing date.
• Track it with Where is My Refund: available 24 hours after e-filing a current-year return, 3–4 days after e-filing a prior-year return, and 4 weeks after mailing a paper return.

Errors, missing forms, or identity-verification checks can delay your refund. Estimate yours with our tax refund calculator and track the payout with our refund timeline and Where Is My Refund guides.

Benefits of Filing Early

• Get your refund faster — e-file + direct deposit typically pays in less than 21 days.
• Reduce identity-theft risk — file before a fraudster files with your SSN.
• More time to fix rejects — missing W-2s, 1099s, or 1095-A errors are easier to correct in February than April.
• More time to plan payment — even if you owe, filing early gives you until April 15 to pay.
• Better preparer availability — slots fill up in late March and early April.

What If You Miss the Deadline?

If you cannot pay the full balance, still file on time and then set up monthly payments — see our IRS payment plan guide for the available options.

How to Get an Extension (Form 4868)

Need more time? File IRS Form 4868 by the April deadline for an automatic 6-month extension to October 15. Three ways: (1) pay via IRS Direct Pay / EFTPS and mark it as an extension, (2) e-file Form 4868 through software or a preparer, (3) mail paper Form 4868. An extension extends filing only — you must still pay owed tax by April. See our step-by-step guide: How to File a Tax Extension. You can also read the overview in our tax extension guide.
