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 from year to year because it depends on when the IRS completes its systems testing and when certain tax documents arrive from employers and financial institutions. For the 2024 tax year, the IRS started accepting returns on January 29, 2024. For 2025 returns, the IRS announced it would begin accepting them on January 27, 2025.

The opening date matters because you cannot file before the IRS systems are ready to receive your return, even if you have all your documents. If you submit a return before the official start date through tax software or a tax preparer, it will be rejected. You will need to resubmit once the filing season opens.

The IRS publishes the opening date on its website and through tax software companies several weeks in advance. You can find the current year's date on IRS.gov under "Filing Season" or by checking with your tax preparer or software provider.

Key Takeaways

  • The IRS filing season opens in late January or early February each year, with the exact date announced weeks in advance on IRS.gov.
  • You cannot file your return before the official opening date, even if you have completed your tax forms and gathered all required documents.
  • Tax software and tax preparers will reject returns submitted before the IRS systems are ready, and you will need to resubmit after the opening date.
  • The opening date shifts year to year because it depends on IRS system testing and the arrival of W-2s, 1099s, and other tax documents from employers and financial institutions.

Why the IRS does not open filing season until late January

The IRS waits until late January because employers, banks, and other payers must send tax documents to both the IRS and to you by January 31 each year. The IRS needs time to receive and process those documents — primarily W-2s from employers and 1099s from banks, investment firms, and other sources — before it can safely accept returns. If the IRS opened filing season before those documents arrived, returns filed early would be incomplete and likely rejected or flagged for review.

The IRS also uses the weeks before filing season to test its computer systems and make sure they can handle the volume of returns that will arrive. This testing period typically runs through mid-January. Any major software updates or security patches are completed before the filing season opens.

Some tax documents arrive later than others. For example, mortgage interest statements (Form 1098) and education expense statements (Form 1098-T) often arrive in February. The IRS does not wait for every possible document, but it does wait for the most common ones that most filers need.

What happens if you file before the season opens

If you attempt to file a return before the IRS filing season opens, your return will be rejected by the IRS system. Tax software will show an error message, and your tax preparer will tell you the return cannot be submitted yet. You will not lose your work — you can save your return and resubmit it after the opening date.

Filing early does not give you an advantage in terms of your refund. The IRS processes returns in the order they are received after the filing season opens, not in the order they were prepared. A return submitted on the first day of filing season does not receive faster processing than one submitted in February or March.

When to file if you want a refund quickly

If you expect a refund, filing as soon as the season opens can help you receive it sooner, but only slightly. The IRS typically issues refunds within 21 days of accepting your return if you file electronically and request direct deposit to your bank account. Filing on January 27 versus February 15 might get your refund to you a few weeks earlier, but the difference is not dramatic.

The fastest path to a refund is to file electronically with direct deposit. Paper returns take much longer — often six to eight weeks or more. If you owe taxes instead of receiving a refund, the filing date matters less for your timeline, though filing by the April deadline is legally required.

How to find out the exact opening date each year

The IRS announces the filing season opening date on IRS.gov, usually in November or December of the prior year. You can also find it by searching "IRS filing season" or by calling the IRS at 1-800-829-1040. Tax software companies and tax preparers also receive this information and will display it prominently when you open their platforms.

If you are working with a tax preparer or accountant, they will know the opening date and will contact you when they are ready to file your return. You do not need to track the date yourself if someone else is handling your taxes.

State filing seasons and deadlines

Most states follow the same filing season as the federal IRS, opening in late January. However, some states have slightly different rules or earlier deadlines for certain situations. For example, some states require state returns to be filed by a different date than the federal deadline, or they may have different rules for extensions.

If you file a federal return, you can usually file your state return at the same time through the same tax software or tax preparer. The state filing season opening date is typically the same as the federal date, but you should confirm with your state's tax agency if you have questions.

Frequently Asked Questions

Can I file my taxes before the IRS filing season opens?

No. The IRS will reject any return submitted before the official opening date. You can prepare your return and save it in tax software, but you cannot submit it until the IRS systems are ready. The opening date is announced weeks in advance so you can plan accordingly.

Does filing on the first day of tax season get me a faster refund?

Filing electronically on the first day may get your refund a few weeks sooner than filing in March or April, but the difference is small — usually a few weeks at most. Direct deposit is much more important than filing early. The IRS processes returns in the order received after the season opens, not by preparation date.

What if I need to file before the season opens because I owe taxes?

You still cannot file before the opening date. The IRS system will not accept your return. However, if you owe taxes, you can make an estimated payment to the IRS before filing your actual return. This stops interest and penalties from accruing while you wait for the filing season to open.

Why does the opening date change every year?

The opening date shifts because it depends on when the IRS finishes testing its systems and when W-2s and other tax documents from employers arrive. The IRS needs both of these things to be ready before it can safely accept returns. The date typically falls between late January and early February.

Do state taxes open on the same date as federal taxes?

Most states open their filing season on the same date as the federal IRS. However, some states may have different rules or earlier deadlines for specific situations. Check your state's tax agency website to confirm if you are unsure about your state's opening date.
