The IRS opens 2025 tax return filing on January 27, 2025

The Internal Revenue Service will begin accepting 2025 tax returns on Monday, January 27, 2025. This is the official start of the 2025 filing season. You cannot file before this date, even if you have all your documents ready — the IRS systems straightforward will not accept returns submitted earlier.

The filing important date itself is Tuesday, April 15, 2025. This is the last day to file your return or request an extension without penalty. If you file after April 15 without an extension, you will owe failure-to-file penalties on top of any taxes owed.

The delay between the start of filing season and the important date gives you about 2.5 months to gather documents, complete your return, and submit it. For most people, filing earlier in this window means faster refunds and fewer complications if the IRS has questions about your return.

Key Takeaways

  • The IRS will not accept any 2025 tax returns before January 27, 2025, regardless of how early you have your documents.
  • The tax filing important date is April 15, 2025, and filing after that date without an extension triggers penalties and interest.
  • Refunds typically process within 21 days if you file electronically and choose direct deposit, but this timeline starts only after the IRS accepts your return.
  • If you need more time, you can request an automatic extension by filing Form 4868, which moves your important date to October 15, 2025, but does not extend the time to pay taxes owed.

Why the IRS delays the start of filing season

The IRS does not open filing season on January 1 because tax forms and instructions are not finalized until late January. Employers, financial institutions, and the IRS itself need time to test their systems and may support that documents like W-2s, 1099s, and other income statements are being transmitted correctly.

The delay also gives the IRS time to update its software to reflect any tax law changes that took effect for the 2025 tax year. If the IRS opened filing too early, returns filed in early January might be rejected or processed incorrectly because the system was not yet configured for the current year's rules.

Starting on January 27 is a compromise: it gives the IRS enough time to prepare while still leaving taxpayers nearly three months to file before the April 15 important date.

When you will receive your refund

If you file electronically and choose direct deposit, the IRS typically issues refunds within 21 days of accepting your return. This 21-day window begins on the date the IRS accepts your return, not the date you submit it. For returns filed in late January or early February, you can expect refunds in mid-to-late February or early March.

Refunds filed by mail take significantly longer — often six to eight weeks or more. The IRS must receive the return, open it, scan it, and enter the data into its system before processing can begin. If you are expecting a refund, electronic filing with direct deposit is the fastest route.

The IRS publishes a Where's My Refund tool on its website where you can check the status of your refund after it has been accepted. This tool updates once per day and shows whether your return is still being processed, approved, or sent to your bank.

What documents you need before January 27

You do not have to wait until January 27 to gather your documents. In fact, starting early means you will be ready to file as soon as the IRS opens. Most people need a W-2 from each employer, a 1099 for self-employment or investment income, and records of deductions or credits they plan to claim.

Employers are required to send W-2s by January 31, 2025. If you have not received one by early February, contact your employer or the IRS. Financial institutions send 1099s on a similar timeline. If you are waiting for these forms, you can file a return using estimates and then file an amended return once the actual forms arrive, though this creates extra work.

For deductions, gather receipts for charitable donations, medical expenses, property taxes, mortgage interest, and business expenses. For credits like the Earned Income Tax Credit or Child Tax Credit, have your Social Security numbers, dependent information, and proof of childcare costs ready. Having these documents organized before January 27 means you can file within hours of the filing season opening.

Filing before the rush versus filing at the last minute

Filing early in the season — in late January or February — has several advantages. Refunds arrive faster because the IRS processes returns in the order it receives them. Early filers also have more time to respond if the IRS has questions or needs additional information about their return.

Filing in March or early April means you are in a much larger crowd. The IRS processes millions of returns in the final weeks before April 15, which can slow down refund processing. If there is an error on your return, you may not hear about it until after the important date, and you will have less time to correct it.

Filing at the very last minute — on April 14 or 15 — is risky. If you encounter a technical problem with your tax software or the IRS website, you may miss the important date. If you owe taxes, filing late means you start accruing failure-to-file penalties when ready after April 15.

What to do if you cannot file by April 15

You can request an automatic extension by filing Form 4868 (process for Automatic Extension of Time to File U.S. Individual Income Tax Return). This form moves your filing important date to October 15, 2025. You do not need a reason to request an extension, and the IRS grants it automatically if you file the form on time.

Important: an extension to file is not an extension to pay. If you owe taxes, they are due on April 15 even if you have an extension to file. If you do not pay by April 15, you will owe interest and penalties on the unpaid amount, even if you file your return in October. To avoid these charges, estimate what you owe and pay it by April 15, then file your actual return later.

You can file Form 4868 electronically through tax software, by mail, or by phone. Filing it electronically is the fastest and most reliable method. The form itself is straightforward and takes only a few minutes to complete.

State tax filing important date

Most states follow the federal April 15 important date for income tax returns. However, some states have different dates or do not have an income tax at all. If you live in a state with income tax, check your state's tax agency website to confirm the important date — it is usually the same as the federal important date, but not always.

If you file a federal extension, most states automatically grant you an extension as well, moving your state important date to October 15. A few states have different rules, so verify with your state tax agency if you are filing an extension.

Frequently Asked Questions

Can I file my 2025 return before January 27?

No. The IRS will not accept any 2025 tax returns before January 27, 2025. If you submit a return through tax software before that date, it will be rejected or held until the filing season opens. You can prepare your return in advance, but you cannot submit it to the IRS until January 27.

What happens if I file after April 15 without an extension?

You will owe a failure-to-file penalty, which is typically 5 percent of the unpaid tax for each month your return is late. You will also owe interest on any taxes owed, calculated from the original April 15 important date. Filing an extension before April 15 eliminates the failure-to-file penalty but not the interest if you owe taxes.

How long does it take to get a refund if I file on January 27?

If you file electronically with direct deposit on January 27, you can expect your refund within 21 days, typically by mid-February. The exact timing depends on your bank and whether the IRS needs to verify any information on your return. Mail-filed returns take much longer, often six to eight weeks.

Do I need to file my state return on the same day as my federal return?

No. State filing important date usually match the federal important date of April 15, but you can file your state return separately and on a different date if you choose. However, most people file both at the same time using tax software that handles both returns together.

What if my employer has not sent my W-2 by January 27?

You can file your return using an estimate of your W-2 income, then file an amended return once you receive the actual W-2. However, this creates extra work. If your employer is late sending W-2s, contact them first. If they do not send it by January 31, you can contact the IRS, which will investigate and may issue you a substitute W-2.
