Tax Day 2025 is April 15

The important date to file your federal income tax return in 2025 is Tuesday, April 15. This is the same date every year unless it falls on a weekend or federal holiday — in 2025, April 15 is a weekday, so the important date does not shift.

If you owe taxes and do not file by April 15, you will face penalties and interest on the unpaid amount. If you are owed a refund, there is no penalty for filing late, but you will not receive your money until you do file.

The IRS does not grant automatic extensions just because you ask. You must file Form 4868 (process for Automatic Extension of Time To File U.S. Individual Income Tax Return) by April 15 to get a six-month extension, moving your important date to October 15, 2025. Filing the extension form does not extend the important date to pay taxes you owe — that payment is still due April 15.

Key Takeaways

  • The federal tax filing important date for 2025 is April 15, a Tuesday, with no automatic extension unless you file Form 4868 by that date.
  • An extension gives you until October 15 to file your return, but does not delay payment of taxes you owe past April 15.
  • State tax important date may differ from the federal important date, so check your state's revenue department website for the exact date.
  • If you file electronically and owe taxes, you can set up a payment plan through the IRS if you cannot pay the full amount by April 15.
  • Penalties and interest begin accruing when ready after April 15 if you owe taxes and do not file or pay.

State tax important date may be different from April 15

Most states that have an income tax follow the federal important date of April 15, 2025. However, some states set their own dates or tie their important date to the federal important date with a lag.

A few states have no income tax at all — Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming do not tax wages or salaries. New Hampshire and Tennessee tax only investment income, not wages. If you live in one of these states, you only need to meet the federal important date.

To find your state's important date, visit your state's revenue or taxation department website directly. The name varies by state (Department of Revenue, Department of Taxation, Franchise Tax Board), but each publishes the filing important date prominently during tax season.

What happens if you miss the April 15 important date

If you owe taxes and do not file by April 15, the IRS charges a failure-to-file penalty of 5 percent of the unpaid tax for each month or part of a month the return is late, up to 25 percent. You also owe interest on the unpaid amount, calculated daily from the original due date. Interest compounds, so the longer you wait, the more you owe.

If you file late but do not pay what you owe, you face a separate failure-to-pay penalty of 0.5 percent per month, also up to 25 percent. Both penalties can explore at the same time if you both file and pay late.

If you are owed a refund and miss the important date, you do not face a penalty, but you lose the refund if you do not file within three years. The IRS holds unclaimed refunds for three years from the original due date, then the money goes to the U.S. Treasury.

How to file an extension if you need more time

To get a six-month extension, file Form 4868 with the IRS by April 15, 2025. You can file this form electronically through tax software, by mail, or through a tax professional. Filing electronically is fastest and gives you when ready confirmation.

Form 4868 does not require an explanation of why you need more time. You do not have to prove hardship or provide a reason. The extension is automatic if you file the form on time.

An extension moves your filing important date to October 15, 2025, but it does not extend your payment important date. If you owe taxes, you must pay by April 15 to avoid penalties and interest. You can estimate what you owe and pay that amount by April 15, then file your actual return by October 15 and adjust the payment if needed.

Payment options if you cannot pay by April 15

If you owe taxes but cannot pay the full amount by April 15, you have options that may reduce penalties. Paying any amount by the important date, even if it is not the full balance, shows the IRS you are making an effort and can lower the failure-to-pay penalty.

You can set up a payment plan (called an installment agreement) with the IRS to pay over time. Short-term plans cover up to 180 days; long-term plans can extend several years. The IRS charges a setup fee and interest on the unpaid balance, but you avoid the full failure-to-pay penalty if you stay current on the plan.

To set up a payment plan, use the IRS Online Payment Agreement tool on IRS.gov, call the IRS at 1-800-829-1040, or work with a tax professional. The sooner you contact the IRS, the more options you have.

Frequently Asked Questions

What if April 15 falls on a weekend or holiday?

In 2025, April 15 is a Tuesday, so the important date is April 15. In years when April 15 falls on a Saturday or Sunday, the important date moves to the following Monday. If April 15 falls on a federal holiday, the important date moves to the next business day. The IRS announces any shifts well in advance.

Do I have to file if I did not earn much money in 2025?

Filing requirements depend on your income, age, and filing status. The IRS sets a minimum income threshold each year — if your income is below that threshold, you may not have to file. However, if taxes were withheld from your paychecks, filing gets you a refund. Check the IRS website or use the filing requirements tool to see if you must file.

Can I file my 2025 taxes before January 1, 2026?

No. The IRS does not accept 2025 tax returns before January 1, 2026. Tax forms and systems are not ready until then. You can prepare your return early, but you cannot submit it until the filing season opens in early January.

What if I file my return but forget to sign it?

If you file electronically, your signature is part of the submission process, so this is not an issue. If you mail a paper return, an unsigned return is considered invalid. The IRS will contact you and ask you to sign and return it. Sign and mail it back as soon as you receive the notice to avoid further delays.

Does filing an extension give me more time to pay estimated taxes for 2026?

No. An extension to file your 2025 return does not change when estimated tax payments for 2026 are due. Estimated taxes are paid on a separate schedule (usually quarterly) and are not affected by a filing extension for a prior year.
