Tax Return Day is April 15 in most years, but the exact date shifts when April 15 falls on a weekend or holiday

The federal deadline to file your tax return or request an extension is April 15 in most years. If April 15 falls on a Saturday or Sunday, the deadline moves to the following Monday. If a federal holiday falls on April 15 or the Monday after it, the deadline moves to the next business day. In 2024, April 15 was a Monday, so the deadline was April 15. In 2025, April 15 is a Tuesday, so the deadline is April 15.

This deadline applies whether you file on paper or electronically. It also applies whether you owe money or expect a refund. Missing the deadline without filing an extension results in a failure-to-file penalty, which the IRS charges as a percentage of unpaid tax.

You do not have to wait until April 15 to file. The IRS begins accepting returns in late January each year. Filing early can mean receiving a refund sooner, since the IRS processes returns in the order they arrive.

Key Takeaways

  • The standard tax deadline is April 15, but it shifts to the next business day if April 15 falls on a weekend or federal holiday.
  • You can file your return anytime after late January; filing early does not trigger an audit and may get you a refund faster.
  • If you cannot file by April 15, you can request an automatic six-month extension, which moves your deadline to October 15.
  • An extension gives you more time to file, but it does not extend the deadline to pay taxes you owe — those are still due April 15.
  • The IRS charges penalties for filing late without an extension, and separate penalties for paying late.

How to request an extension if you cannot file by April 15

You can request an automatic six-month extension by filing Form 4868 (Application for Automatic Extension of Time to File U.S. Individual Income Tax Return) before April 15. Filing this form moves your deadline to October 15. You do not need a reason to request the extension, and the IRS grants it automatically.

You can file Form 4868 on paper, electronically through tax software, or through a tax professional. If you file electronically, you receive confirmation immediately. If you file on paper, mail it to the IRS address listed in the form instructions for your state.

Important: an extension to file is not an extension to pay. If you owe federal income tax, that payment is still due April 15, even if you file Form 4868. If you cannot pay by April 15, you can set up a payment plan with the IRS, but you will owe interest and penalties on the unpaid balance.

What happens if you miss the April 15 deadline without an extension

The IRS charges a failure-to-file penalty if you file after April 15 without an extension. The penalty is 5 percent of the unpaid tax for each month or part of a month that your return is late, up to a maximum of 25 percent. This penalty applies even if you are owed a refund.

If you owe tax and also pay late, the IRS charges a separate failure-to-pay penalty of 0.5 percent per month, up to 25 percent. Interest also accrues on any unpaid tax from April 15 onward, compounded daily.

If you file very late — more than 60 days after the deadline — the minimum penalty is the smaller of $435 (as of 2024) or 100 percent of the unpaid tax. The IRS may also pursue collection action, including wage garnishment or bank levies.

When the IRS starts accepting returns each year

The IRS typically begins accepting tax returns in late January. The exact date varies slightly year to year, but it is usually around January 27 or 28. The IRS announces the opening date in December of the previous year on its website.

Tax software companies and tax professionals can often file returns a few days before the IRS officially opens, but your return will not be processed until the IRS begins accepting. Filing early does not speed up processing; the IRS processes returns in the order they arrive, regardless of when you submitted them.

If you are waiting for a document like a W-2 or 1099 form from your employer or a financial institution, you may want to wait to file. Employers must send W-2s by January 31, and most financial institutions send 1099s by the same date. Filing before you have all your documents can result in errors that trigger an IRS notice later.

State tax deadlines and how they differ from federal

Most states that have an income tax use the same April 15 deadline as the federal government. However, some states have different rules. A few states do not have an income tax at all, including Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming.

If you live in a state with an income tax and you file a federal extension, most states automatically extend your state deadline as well. However, some states have their own extension rules. Check your state's tax agency website to confirm whether your state extension is automatic or requires a separate form.

If you live in one state but work in another, you may owe tax to both states. Each state has its own deadline and rules. Some states offer credits for tax paid to other states to prevent double taxation.

How to track your return after you file

Once you file your return, you can track its status using the IRS's Where's My Refund? tool on IRS.gov. This tool shows whether the IRS has received your return, whether it is being processed, and when your refund will be issued (if you are owed one). You can check the status 24 hours after you file electronically, or about four weeks after you mail a paper return.

The IRS typically issues refunds within 21 days of accepting your return if you file electronically and choose direct deposit. Paper returns take longer — usually six to eight weeks. If your refund is delayed beyond these timeframes, the Where's My Refund? tool will show you why.

If the IRS needs more information from you, it will send you a notice by mail. Do not wait for a phone call; the IRS does not initiate contact by phone about your return.

Frequently Asked Questions

Can I file my tax return before January?

No. The IRS does not accept returns before late January each year. If you try to file before the IRS opens, your tax software or tax professional will hold your return and submit it automatically once the IRS begins accepting. You cannot file on paper before the IRS opens.

Do I have to file by April 15 if I do not owe any tax?

No legal deadline applies if you owe no tax. However, if you are owed a refund, filing by April 15 ensures you receive it within the normal processing window. If you file late, your refund may be delayed, and you lose the opportunity to use that money sooner.

What if April 15 falls on a holiday in my state?

The federal deadline is based on federal holidays, not state holidays. If April 15 falls on a federal holiday (like Emancipation Day in Washington, D.C.), the deadline moves to the next business day. State holidays do not affect the federal deadline, though they may affect state tax deadlines in some cases.

If I file an extension, do I have to pay anything by April 15?

You do not have to file your return by April 15 if you file Form 4868, but you must pay any tax you owe by April 15. If you cannot pay the full amount, you can set up an installment agreement with the IRS, but interest and penalties will accrue on the unpaid balance.
