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 agency finishes testing its systems 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, the IRS began accepting returns 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. Filing as soon as the season opens can reduce the time between when you file and when you receive a refund, though it also means filing before some year-end tax documents have arrived.

The filing season does not end on a fixed date. You can file any time during the year, but if you owe taxes, penalties and interest begin to accrue on April 15. If you expect a refund, there is no penalty for filing late, though you will wait longer to receive your money.

Key Takeaways

  • The IRS opens its filing season in late January each year, with the exact date announced in the fall of the previous year.
  • You cannot file before the IRS systems are ready, even if you have your W-2s and other documents.
  • Filing early in the season can speed up your refund, but some tax documents may not have arrived yet.
  • The April 15 deadline applies only to taxes owed; if you expect a refund, you can file anytime without penalty.

How to find the exact opening date for this year

The IRS announces the filing season opening date in October or November of the previous year. You can find this date on IRS.gov by searching for "filing season" or looking at the IRS newsroom. The agency also posts the date on its social media accounts and sends notifications to tax professionals who are registered with the IRS.

If you use tax software or work with a tax preparer, they will know the opening date and will not let you file before the IRS is ready. The software simply will not submit your return until the systems are live.

Why the IRS does not open on the same date every year

The IRS must test all its systems before opening to the public. This testing takes several weeks and cannot be rushed. The agency also waits for W-2s, 1099s, and other documents to flow in from employers and financial institutions, since the IRS cross-checks these documents against the returns you file. If the IRS opened before these documents arrived, it would have to process returns twice.

Congress also sometimes passes new tax laws in December or January that require the IRS to reprogram its systems before opening. This happened in recent years when stimulus payments and child tax credit changes were enacted late in the previous year.

What to do if you need to file before the season opens

If you need a refund urgently and the filing season has not yet opened, you have limited options. You cannot file electronically, but you can mail a paper return to the IRS. Paper returns are processed more slowly than electronic ones, and the IRS will not begin processing them until after the filing season opens anyway, so mailing early does not speed things up.

If you owe taxes and the April 15 deadline is approaching, you can file a paper return and pay what you owe by the deadline to avoid penalties. The IRS will process the return after the season opens.

How long refunds take after you file

The IRS aims to issue refunds within 21 days of accepting your return if you file electronically and choose direct deposit. If you file early in the season, you may receive your refund within this timeframe. If you file later or choose a paper check, the wait is longer.

Refunds can take longer if the IRS needs to verify information on your return, if you claimed certain credits like the Earned Income Tax Credit, or if there are errors or inconsistencies. The IRS will contact you if it needs more information.

Filing before all your documents arrive

Many people file in early February because they want their refund quickly, but not all W-2s and 1099s have arrived by then. If you file before receiving a document, you may have to file an amended return later if the information on that document differs from what you reported.

To reduce this risk, wait until you have received all documents from your employer, banks, investment firms, and any other sources of income. If you must file early, keep copies of the documents you did receive and be prepared to amend if needed.

Frequently Asked Questions

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

No. The IRS systems will not accept returns before the official opening date, even if you file electronically through tax software. You can mail a paper return, but the IRS will not process it until after the season opens. Filing early does not speed up processing.

What happens if I file after April 15?

If you expect a refund, there is no penalty for filing late. You will simply receive your refund later. If you owe taxes, you will owe penalties and interest on the unpaid amount from April 15 onward, even if you file months later.

How do I know when my refund will arrive?

The IRS aims to issue refunds within 21 days of accepting your return if you file electronically and choose direct deposit. You can track your refund status on IRS.gov using the "Where's My Refund?" tool, which updates once per day.

Should I file as soon as the season opens?

Filing early can speed up your refund, but some tax documents may not have arrived yet. If you file before receiving all your W-2s and 1099s, you may need to amend your return later. Weigh the benefit of an earlier refund against the risk of having to file an amended return.
