The IRS filing season for 2025 tax returns begins January 27, 2025

The Internal Revenue Service will begin accepting and processing 2025 tax returns on Monday, January 27, 2025. This is the official start date each year, and it applies whether you file by mail, through tax software, or with a tax professional. You can file before this date, but the IRS will not process your return or issue refunds until after January 27.

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 cannot meet this important date, you can request a six-month extension, which moves your important date to October 15, 2025 — but an extension to file is not an extension to pay. If you owe taxes, interest and penalties begin accruing on April 15 regardless of whether you filed.

Key Takeaways

  • The IRS will not process any 2025 returns before January 27, 2025, even if you submit them earlier.
  • Your tax return must be filed or postmarked by April 15, 2025, or you must request an extension before that date.
  • If you expect a refund, filing early after January 27 typically means you receive it faster than filing in March or April.
  • An extension to file does not delay when taxes are due; if you owe money, it is due April 15 even if you file in October.
  • You can file your return using IRS Free File, tax software, or a tax professional at any time after January 27.

Why the IRS delays the start of filing season

The IRS does not open filing season on January 1 because employers, financial institutions, and other payers need time to prepare and mail tax documents. Your employer must send you a W-2 by January 31. Banks and investment firms must send 1099 forms (interest, dividends, capital gains) by the same date. The IRS waits until late January to give these documents time to reach you and to allow their systems to process the volume of returns that arrive when ready after the season opens.

Starting on January 27 also gives the IRS a buffer to test their systems and catch errors before millions of returns arrive. This timing has been consistent for several years and is unlikely to change unless Congress passes new legislation.

What documents you need before you file

Do not file until you have received all the tax documents from 2024. Gather these before January 27:

  • W-2 forms from each employer you worked for in 2024. Your employer must mail this by January 31.
  • 1099 forms if you received interest, dividends, capital gains, freelance income, or other non-wage income. These come from banks, brokerages, and clients.
  • 1098 forms if you paid mortgage interest or student loan interest. Your lender sends these.
  • Records of estimated tax payments if you made quarterly payments to the IRS during 2024.
  • Receipts or records for deductions you plan to claim, such as charitable donations, medical expenses, or business expenses if you are self-employed.
  • Last year's tax return for reference, especially if your situation has not changed much.

If you are missing a document by early February, contact the issuer directly. Most will resend or provide a copy. Do not guess at amounts — using incorrect figures can trigger an audit or delay your refund.

How to file after January 27

Once the IRS begins accepting returns on January 27, you have three main routes:

IRS Free File: If your household income was $79,000 or less in 2024, you may use IRS Free File through participating tax software companies. This is a partnership between the IRS and private software makers. You access it through IRS.gov, and the software is free. You do not pay filing fees. Income limits and available forms vary by provider.

Tax software: Commercial software like TurboTax, H&R Block, TaxAct, and others charge fees ranging from $0 to $200+ depending on the complexity of your return and which version you buy. These programs walk you through questions, calculate your refund or tax owed, and file electronically. Most offer state return filing for an additional fee.

Tax professional: A CPA, enrolled agent, or tax preparer can file for you. They typically charge $150 to $500+ depending on return complexity and your location. A professional is useful if you are self-employed, have investment income, own rental property, or had major life changes in 2024.

Electronic filing is faster than mailing a paper return. The IRS processes e-filed returns in 21 days or less if there are no errors. Paper returns take 4 to 6 weeks.

Refund timing after you file

If you are owed a refund, the IRS issues most refunds within 21 days of accepting your return. This does not mean 21 days from when you file — it means 21 days from when the IRS actually processes it. If you file on January 27, processing may take a few days, so expect your refund in early to mid-February at the earliest.

Refunds filed later in the season (March and April) may take longer because the IRS is processing millions of returns simultaneously. Filing in February or early March generally results in faster refunds than waiting until April.

The IRS deposits refunds directly to your bank account if you provide your routing and account numbers. This is faster than a paper check. You can check the status of your refund using the IRS Where's My Refund tool on IRS.gov starting 24 hours after you file electronically.

What to do if you cannot file by April 15

If you know you will not have all your documents or will not be ready to file by April 15, request an automatic extension. You do this by filing Form 4868 with the IRS. You can file this form electronically through tax software or by mail. Filing Form 4868 moves your filing important date to October 15, 2025.

An extension to file does not reduce what you owe in taxes. If you expect to owe money, you should pay as much as you can by April 15 to avoid interest and penalties. If you cannot pay the full amount, paying something is better than paying nothing. The IRS charges interest on unpaid taxes at a rate set quarterly, plus a failure-to-pay penalty of 0.5% per month.

If you file Form 4868 and later discover you do not need the extension, you can straightforward file your return early. There is no penalty for filing before your extended important date.

Common mistakes to avoid when filing early

Filing as soon as the season opens can save time, but rushing creates errors. The most common mistakes are:

  • Filing before you have received all your W-2 and 1099 forms. If you file without a 1099 and then receive it later, you may have to file an amended return.
  • Entering the wrong Social Security number for yourself, your spouse, or dependents. The IRS will reject the return or delay processing.
  • Claiming a dependent who does not meet the IRS definition. Dependents must live with you for more than half the year, be a U.S. citizen or resident alien, and meet income limits.
  • Mismatching your name or address with what the IRS has on file. Update your address with USPS and the IRS before filing if you moved.
  • Forgetting to sign and date your return if filing on paper. Electronic returns require an electronic signature, which the software handles.

If you make a mistake after filing, you can file an amended return using Form 1040-X. You have three years from the original filing date to amend a return.

Frequently Asked Questions

Can I file my 2025 return before January 27?

You can submit your return to tax software or a tax professional before January 27, but the IRS will not process it until after that date. Your refund will not be issued and your return will not be officially received until after January 27. There is no advantage to preparing early except to have everything ready to file when ready when the season opens.

What happens if I file after April 15?

If you file after April 15 without an extension, you owe a failure-to-file penalty of 5% per month of the tax you owe, up to 25%. You also owe interest on any unpaid taxes. If you filed an extension on time, the penalty does not explore, but interest still accrues if you owe money.

Do I need to file if I did not work in 2024?

You may still need to file if you had income from other sources — interest, dividends, self-employment, or rental property. If you had no income at all and no one can claim you as a dependent, you do not have to file. However, filing may result in a refund if taxes were withheld from your account.

How do I know if I am using the right filing method?

Use IRS Free File if your 2024 income was $79,000 or less. If your income is higher or your return is complex (self-employed, rental income, business losses), use tax software or a tax professional. A tax professional is most useful if you own a business, have multiple income sources, or had major life changes like a divorce or home sale.

Can I file my state return at the same time as my federal return?

Yes. Most tax software allows you to file your state return when ready after your federal return. Some states participate in IRS Free File and offer free state filing. State filing important date usually match the federal important date of April 15, though a few states have different dates. Check your state's tax agency website to confirm.
