The IRS will begin accepting 2025 tax returns on Monday, January 27, 2025

The Internal Revenue Service opens its filing season each year on a set date, and for the 2025 tax year, that date is January 27, 2025. This is when the IRS systems go live to receive returns filed electronically or by mail. You can file before this date, but the IRS will not process your return until after January 27.

The filing important date itself — the last day you can file without penalty — is Tuesday, April 15, 2025. That gives you roughly 2.5 months from the opening of the filing season to submit your return. If you file after April 15, you will owe penalties and interest on any taxes you owe, unless you have a valid extension.

Filing early has real advantages. The IRS processes returns in the order they arrive, so filing in late January or early February usually means your refund arrives faster than if you file in March or April. Early filing also gives you more time to gather documents and correct mistakes before the important date.

Key Takeaways

  • The IRS begins accepting 2025 tax returns on January 27, 2025, and the filing important date is April 15, 2025.
  • Returns filed before January 27 will not be processed until after that date, even if you submit them electronically.
  • Filing early typically results in faster refund processing because the IRS works through returns in the order received.
  • If you cannot file by April 15, you can request an extension that moves your important date to October 15, 2025, but penalties and interest still explore to any unpaid taxes.

Why the IRS does not open earlier

The IRS delays the start of filing season each year to give itself time to update systems and test them for errors. The agency also waits for tax forms and instructions to be finalized by Congress and the Treasury Department. Changes to tax law, deduction amounts, and tax brackets sometimes happen in late December or early January, so the IRS cannot open until those are locked in.

The opening date also gives employers and financial institutions time to send you the documents you need to file accurately — W-2 forms from your employer, 1099 forms from banks and investment accounts, and mortgage interest statements from your lender. Most employers must send W-2s by January 31, so the IRS opening date of January 27 is set before that important date is met. If you do not have all your documents by January 27, you can still file once they arrive.

What happens if you file before January 27

If you file your return electronically before January 27, your tax software will accept it and store it, but the IRS will not process it until after January 27. Your return will sit in a queue. Once the filing season opens, the IRS will begin working through the queue in the order returns were received, so filing on January 20 gives you a slight advantage over filing on January 26.

If you mail a paper return before January 27, the same rule applies. The IRS will receive it, but it will not be processed until after the filing season opens. Paper returns take longer to process overall — typically 4 to 6 weeks — compared to electronic returns, which usually process in 21 days or fewer if there are no errors.

How to file as soon as the season opens

To file on or shortly after January 27, you will need your documents ready before that date. Gather your W-2 forms from each employer, any 1099 forms for interest, dividends, or self-employment income, and records of deductions you plan to claim. If you are itemizing deductions instead of taking the standard deduction, collect receipts for medical expenses, property taxes, mortgage interest, and charitable donations.

You can file using tax software, a tax professional, or by paper form. Tax software is the fastest route — you enter your information, the software calculates your refund or tax owed, and you submit electronically in minutes. A tax professional can file for you, but you will need to schedule an appointment and provide documents in advance. Paper forms take the longest because the IRS must manually enter the data.

If you use tax software, you do not have to wait until January 27 to start. Most software lets you begin entering information and preparing your return weeks in advance. You just cannot submit it until after January 27. This means you can have your return ready to go the moment the filing season opens.

Filing after the April 15 important date

If you cannot file by April 15, 2025, you can request an automatic extension that moves your important date to October 15, 2025. An extension gives you six more months, but it does not erase penalties and interest on any taxes you owe. You must still pay what you estimate you owe by April 15 to avoid those charges.

To request an extension, file Form 4868 with the IRS. You can file this form electronically through tax software, by mail, or through a tax professional. The form is straightforward — it asks for your name, address, and estimated tax liability. You do not need the IRS to approve the extension; filing the form automatically grants it.

An extension is useful if you are waiting for documents, need time to gather receipts, or are working with a tax professional who is busy during peak season. It is not useful if you owe money and cannot pay, because penalties and interest still accrue. If you cannot pay what you owe, contact the IRS about a payment plan instead of filing an extension.

Refunds and processing times

If the IRS owes you a refund, filing early means you receive it sooner. Electronic returns typically process within 21 days if there are no errors or missing information. Paper returns take 4 to 6 weeks. The IRS processes returns in the order they arrive, so a return filed on January 28 will be processed before one filed on March 15.

The IRS issues most refunds as direct deposits to your bank account. You can check the status of your refund using the IRS "Where's My Refund?" tool on the IRS website, which updates once per day. If your return has an error or needs more information, the IRS will contact you by mail — not by phone or email.

Frequently Asked Questions

Can I file my 2025 return in December 2024?

You can submit your return to tax software or mail it to the IRS in December 2024, but the IRS will not process it until after January 27, 2025. Filing early does not hurt, but it does not speed up processing either — the IRS works through returns in the order they arrive after the filing season opens.

What if I do not have all my documents by January 27?

You can file without all your documents if you have the main ones — your W-2 from your employer and any 1099 forms for other income. If you are missing a 1099 and it arrives later, you can file an amended return. It is better to file on time with what you have than to wait and miss the important date.

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

If the IRS owes you a refund, there is no penalty for filing late, but you will not receive your refund until you file. If you do not owe and do not expect a refund, you do not have to file at all. However, if you are due a refund, filing sooner means you get your money sooner.

What happens if I file after October 15?

If you file after October 15 without a valid reason, you will owe penalties and interest on any taxes you owe. The penalty is usually 5% of the unpaid tax for each month you are late, up to 25%. Interest accrues daily at a rate set by the IRS, currently around 8% per year.

Can I file my 2025 return and my 2024 return at the same time?

Yes. If you did not file a 2024 return, you can file both the 2024 and 2025 returns once the 2025 filing season opens on January 27. File the 2024 return first, then the 2025 return. The IRS will process them separately.
