The IRS opens its filing season on January 27, 2025

The Internal Revenue Service begins accepting 2025 tax returns on January 27, 2025. This is the official start date each year when the IRS systems are ready to receive returns from tax software, tax professionals, and people filing by mail. You can file before this date, but the IRS will not process your return until after January 27.

The IRS sets this date each year to allow time for employers and financial institutions to send W-2 forms, 1099 forms, and other income documents to both the IRS and to you. If you file before these documents arrive, you may have to file an amended return later if the information does not match what you reported.

Filing early does not speed up your refund if you file before January 27. The IRS will hold your return and begin processing it on the official start date. If you are owed a refund and you file electronically with direct deposit, you can typically expect your refund within 21 days of the IRS accepting your return.

Key Takeaways

  • The IRS begins accepting 2025 returns on January 27, 2025, and will not process returns filed before that date.
  • Filing before January 27 does not speed up your refund; the IRS processes all returns starting from the official opening date.
  • W-2 forms from employers and 1099 forms from banks and investment firms must reach you by January 31, 2025, so waiting until late January or early February gives you time to gather all documents.
  • If you file electronically with direct deposit, refunds typically arrive within 21 days of the IRS accepting your return.
  • You can file by mail at any time, but the IRS will not begin processing paper returns until after January 27.

Why the IRS waits until late January to open filing season

The IRS does not open filing season when ready after the new year because employers, banks, and investment firms need time to prepare and send income documents. Employers must issue W-2 forms to employees by January 31. Banks and brokerages must send 1099 forms (for interest, dividends, capital gains, and other income) by the same date. The IRS itself must receive copies of these forms from employers and financial institutions before it can safely process individual returns.

If you file before these documents reach you, your return may not match the information the IRS receives from your employer or bank. This mismatch can trigger a notice from the IRS asking you to explain the difference, or it can delay your refund while the IRS verifies the numbers. Filing after you have received all your income documents reduces the chance of this problem.

What documents you need before you file

Gather these documents before you sit down to file, whether you use tax software, a tax professional, or file by hand:

  • W-2 forms from each employer you worked for in 2025. Your employer must send this to you by January 31.
  • 1099 forms if you received interest, dividends, capital gains, rental income, freelance income, or other income outside of a regular paycheck. The type of 1099 depends on the income source.
  • Social Security number or Individual Taxpayer Identification Number (ITIN) for yourself and anyone you claim as a dependent.
  • Prior year tax return (optional but helpful) to check if anything has changed in your filing status or deductions.
  • Records of deductions if you itemize: mortgage interest statements, property tax records, charitable donation receipts, medical expense records, or business expense records.
  • Proof of health insurance or records of any payments you made toward health insurance premiums, if required by your situation.

If you are missing a W-2 or 1099 by early February, contact your employer or the financial institution directly. You can also file a return based on your best estimate and amend it later when the document arrives, though this creates extra work.

Filing electronically versus filing by mail

The IRS accepts returns by mail at any time during the year, but paper returns are processed much more slowly than electronic returns. If you mail your return on January 15, the IRS will not begin processing it until after January 27, and then it will move through the system at a slower pace than electronic returns. Processing times for paper returns can stretch to several months, especially during the peak filing season in February and March.

Electronic filing through tax software or a tax professional begins on January 27 and processes much faster. If you file electronically with direct deposit, the IRS typically sends your refund within 21 days. If you file electronically and request a check, add another week or two for the check to arrive by mail.

The IRS offers free electronic filing through IRS Free File if your income is below a certain threshold (the income limit changes each year). You can also use commercial tax software, hire a tax professional, or file through a community organization that offers free tax preparation.

What happens after you file

Once you file your return electronically, the IRS sends you an acknowledgment within 24 hours confirming that your return was received. This is not the same as acceptance. The IRS then reviews your return for errors, missing information, and anything that does not match documents they have received from employers or financial institutions.

If your return is accepted without problems, the IRS processes your refund. You can track the status of your refund using the IRS Where's My Refund tool on the IRS website, which updates once per day. If there is a problem with your return, the IRS will send you a notice by mail explaining what needs to be corrected.

If you owe taxes instead of receiving a refund, you can pay online, by phone, by mail, or through an installment agreement if you cannot pay the full amount at once.

important date and extensions

The important date to file your 2025 tax return is April 15, 2026, unless that date falls on a weekend or holiday. If you cannot file by April 15, you can request an automatic extension that gives you until October 15, 2026. An extension gives you more time to file, but it does not extend the important date to pay taxes you owe. If you owe money and do not pay by April 15, you will owe interest and penalties on the unpaid amount, even if you have an extension to file.

To request an extension, file Form 4868 (process for Automatic Extension of Time to File U.S. Individual Income Tax Return) by April 15. You can file this form electronically through tax software or by mail.

Frequently Asked Questions

Can I file my 2025 taxes before January 27?

You can prepare your return and submit it to tax software or a tax professional before January 27, but the IRS will not process it until after that date. If you file by mail, you can mail it anytime, but the IRS will not begin processing paper returns until after January 27. Filing early does not speed up your refund.

What if I do not have all my W-2s and 1099s by January 27?

You can wait to file until you have all your documents, or you can file based on your best estimate and amend your return later when missing documents arrive. Employers must send W-2s by January 31 and financial institutions must send 1099s by the same date. If a document is late, contact the employer or institution directly to request it.

How long does it take to get a refund after I file?

If you file electronically with direct deposit, the IRS typically sends your refund within 21 days of accepting your return. If you request a check by mail, add another week or two. Paper returns take much longer — sometimes several months during peak filing season.

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

No. If you do not owe taxes and do not expect a refund, you are not required to file. However, if you are owed a refund, you must file to receive it. There is no time limit on how long you can wait to claim a refund, but the IRS typically keeps refunds for three years before they are forfeited.

What if I cannot file by April 15?

File Form 4868 by April 15 to request an automatic extension until October 15. An extension gives you more time to file your return, but you must still pay any taxes you owe by April 15 to avoid interest and penalties.
