The IRS begins accepting 2025 tax returns on 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 for income earned in 2025. If you file before that date, the IRS will reject your return — it simply cannot process it yet, even if you have all your documents ready.

The start date matters because it affects when you can file, when you might receive a refund, and how long you have before the April 15 deadline. Filing on January 27 gives you the maximum time to gather documents, correct errors, and receive your refund before the tax year closes.

Key Takeaways

  • The IRS will not accept 2025 tax returns before January 27, 2025, regardless of how early you submit them.
  • Filing early in the season (late January through February) typically results in faster refund processing than filing in March or April.
  • The deadline to file remains April 15, 2025, unless that date falls on a weekend or holiday in your state.
  • You can file electronically as soon as January 27, but paper returns can be mailed anytime before the April 15 deadline.
  • Tax software and tax preparation services usually allow you to prepare your return before January 27, but transmission to the IRS will not succeed until the filing season opens.

Why the IRS has a staggered start date each year

The IRS does not open filing season on the same calendar date every year. Instead, the agency sets a new start date annually, usually in late January. This timing allows the IRS time to update systems, test software, and prepare for the volume of returns it will receive over the next three months.

The staggered approach also gives tax software companies and tax preparation firms time to finalize their systems and ensure they can transmit returns correctly to the IRS. If everyone could file on January 1, the IRS systems would face an immediate surge that could cause delays and errors.

How to prepare before January 27

You do not have to wait until January 27 to get ready. Most people can start gathering documents in early January. Collect your W-2 forms from employers, 1099 forms for freelance or investment income, mortgage interest statements, charitable donation records, and medical expense documentation if you itemize deductions.

You can also open tax software or contact a tax preparer before the filing season opens. Many tax software platforms let you enter your information, answer questions, and build your return before January 27. Once the IRS opens, you can review your completed return and transmit it immediately. This approach often results in faster refunds because your return reaches the IRS on the first day of the season, when processing queues are shortest.

If you use a tax preparer or accountant, contact them in early January to schedule an appointment. Many preparers book up quickly once filing season begins, so scheduling ahead ensures you can file early rather than waiting until March or April.

Refund timing based on when you file

The IRS typically issues refunds within 21 days of accepting your return, but this timeline depends partly on when you file. Returns filed in late January and early February usually process faster because the IRS has fewer returns in its queue. Returns filed in March and April often take longer because the volume is much higher.

If you file electronically and choose direct deposit, you will generally receive your refund faster than if you request a paper check. The IRS also processes returns with no errors or missing information more quickly than returns that require follow-up questions or corrections.

What happens if you file before January 27

If you submit your return to the IRS before January 27, 2025, the IRS will reject it. Your tax software or tax preparer may warn you that the return cannot be transmitted yet, or the transmission may fail silently and you will not know until you check your account status.

If you file on paper and mail your return before January 27, the IRS will receive it but will not process it until after the filing season opens. Your return will sit in a queue until January 27 or later, so mailing early does not speed up processing — it only means your return arrives before the IRS is ready to read it.

The safest approach is to file electronically on or after January 27, 2025. If you use a tax preparer, ask them to hold your return and transmit it on January 27 or shortly after, rather than attempting to file before the season opens.

The April 15 deadline and extensions

The deadline to file your 2025 tax return is April 15, 2025. If April 15 falls on a weekend or holiday, the deadline moves to the next business day. You must file by this date or request an extension before the deadline passes.

An extension gives you until October 15, 2025, to file your return, but it does not extend the deadline to pay taxes owed. If you owe money, you should pay as much as you can by April 15 to avoid penalties and interest. An extension only postpones filing the paperwork, not paying what you owe.

Filing options once the season opens

Once January 27 arrives, you have three main ways to file: electronically through tax software, through a tax preparer or accountant, or by mailing a paper return. Electronic filing is fastest and most reliable. The IRS confirms receipt within 24 to 48 hours, and you can track your return status online.

Tax preparers and accountants file electronically on your behalf, so the timeline is the same as self-filing through software — your return reaches the IRS within hours of submission. Paper returns take longer because they must be physically mailed, received, and manually entered into the IRS system. If you file on paper, mail your return early in the season to allow time for postal delivery and processing.

Frequently Asked Questions

Can I file my 2025 tax return in December 2024?

No. The IRS will not accept 2025 tax returns until January 27, 2025. Any return submitted before that date will be rejected by IRS systems. You can prepare your return in December, but you cannot transmit it to the IRS until the filing season opens.

Will I get my refund faster if I file on January 27?

Usually yes. Filing in late January or early February typically results in refunds within 21 days because the IRS has fewer returns to process. Filing in March or April can take longer due to higher volume, though the IRS still aims for 21-day processing for most returns.

What if I owe taxes instead of getting a refund?

You can file anytime after January 27, but if you owe, you should pay by April 15 to avoid penalties and interest. Filing early does not change your payment deadline — you still owe by April 15 regardless of when you submit your return.

Can I file a paper return before January 27?

You can mail a paper return before January 27, but the IRS will not process it until after the filing season opens. Mailing early does not speed up processing. The IRS will receive it, hold it, and begin processing once January 27 arrives.

What if I miss the April 15 deadline?

You can request an extension before April 15 to file by October 15 instead. However, if you owe taxes, you must pay as much as possible by April 15 to minimize penalties and interest. An extension only postpones filing, not payment.
