The IRS filing season typically opens in late January

The IRS usually begins accepting tax returns in late January or early February each year. The exact date shifts slightly year to year because it depends on when the IRS completes testing of its systems and when certain tax forms are finalized by the Treasury Department. For the 2024 tax year, the IRS started accepting returns on January 29, 2024. For 2025, the IRS announced it would begin accepting returns on January 27, 2025.

The opening date applies to all filing methods: paper returns mailed to the IRS, returns filed through tax software, and returns prepared by tax professionals. You can file before the official opening date, but the IRS will not process your return until after that date. If you mail a return before the opening date, it will sit in the mailroom until processing begins.

The IRS publishes the opening date each year on its official website (irs.gov) and announces it in December of the prior year. Tax software companies and tax preparation services also publish this date prominently when it is announced.

Why the IRS does not open on January 1

The IRS cannot begin processing returns on January 1 because tax forms and instructions are not finalized until late in December or early January. The Treasury Department and IRS coordinate to release final versions of forms like the 1040, schedules, and worksheets. Until those forms are locked in, tax software cannot be programmed to accept and validate the data correctly.

The IRS also uses the weeks before opening to test its computer systems. This testing ensures that the systems can handle the volume of returns that will arrive during peak filing season (typically February through April). A system failure during peak season would delay refunds for millions of people, so the IRS runs extensive tests before opening the gates.

What you can do before the filing season opens

You do not have to wait for the filing season to open to prepare. Gather your documents now: W-2 forms from your employer, 1099 forms for interest or self-employment income, mortgage interest statements, charitable donation receipts, and any other income or deduction records. Organizing these documents before the season opens means you can file within hours of the opening date if you choose.

If you use tax software, you can usually enter your information into the program before the filing season opens. The software will hold your return and let you review it. Once the IRS opens for the season, you can submit it immediately. If you work with a tax professional, you can meet with them and provide documents before the season opens; they will file your return as soon as the IRS is ready to receive it.

How long returns take to process after filing

Processing time depends on how you file. Returns filed electronically (through software or a tax professional) are usually processed within 21 days if there are no errors or missing information. Paper returns take much longer — typically 4 to 6 weeks or more, depending on the volume of mail the IRS receives.

If you are owed a refund, the IRS will issue it after your return is processed. Refunds filed electronically usually arrive within 21 days of filing; paper returns take longer. The IRS does not issue refunds faster if you file early in the season, so filing on January 29 versus March 15 does not change your refund timeline significantly.

What happens if you miss the April 15 deadline

The deadline to file a tax return is April 15 (or the next business day if that date falls on a weekend or holiday). This deadline does not change based on when the filing season opens. If you do not file by April 15, you may owe a failure-to-file penalty, even if you are owed a refund.

You can request an automatic extension to file by October 15, but an extension to file is not an extension to pay. If you owe taxes, you must pay by April 15 to avoid interest and penalties. An extension only gives you more time to submit your return; it does not reduce what you owe.

State tax filing seasons

State tax filing seasons do not always align with the federal IRS opening date. Some states open their filing season before the IRS; others wait until the IRS opens. A few states do not have an income tax at all. Check your state's tax agency website to find out when your state begins accepting returns. The state deadline to file is usually April 15 as well, but some states have different dates.

If you file your federal return through software, the software usually lets you file your state return at the same time, as long as your state has opened its filing season. If your state has not opened yet, you may have to wait or file your state return separately.

Frequently Asked Questions

Can I file my taxes before January 27, 2025?

You can prepare and submit your return to tax software or a tax professional before January 27, but the IRS will not process it until after that date. If you mail a paper return before the opening date, it will not be processed until the season opens. Filing early does not speed up your refund.

What if I file on January 27 and owe taxes?

You must pay any taxes you owe by April 15, regardless of when you file. Filing early does not change the payment deadline. If you file in January and owe money, pay it by April 15 to avoid penalties and interest.

Do I have to file as soon as the season opens?

No. You can file anytime between the opening date and April 15. Filing early may get your refund sooner if you are owed money, but there is no penalty for filing in March or early April. The only deadline that matters is April 15.

Will the IRS open on the same date every year?

No. The opening date shifts year to year because it depends on when forms are finalized and system testing is complete. The IRS announces the opening date in December of the prior year. Check irs.gov in December to find out when the next filing season will begin.
