The IRS opens tax filing on a set date each year, usually in late January or early February

You cannot file your federal tax return before the IRS opens the filing season. The IRS announces the opening date each year, and for the 2024 tax year (returns filed in 2025), filing opened on January 29, 2025. The exact date shifts slightly year to year because the IRS needs time after December 31 to update its systems and test them with tax software companies.

Filing before the IRS opens means your return will be rejected. Tax software will not let you submit, and if you mail a paper return, the IRS will send it back. The IRS publishes its opening date on IRS.gov and announces it in December of the prior year, so you can plan ahead.

State tax filing often opens on the same day as federal filing, though some states open a few days earlier or later. Check your state's tax agency website for the exact date if you file a state return.

Key Takeaways

  • Federal tax filing opens in late January or early February each year; the IRS announces the exact date in December of the prior year.
  • You cannot file before the IRS opens the season, whether you file electronically or by mail.
  • State filing dates vary by state and may differ from the federal opening date by a few days.
  • Filing early after the season opens can speed up your refund if you are due one.
  • The IRS needs the time between January 1 and the opening date to process prior-year returns and update systems.

Why the IRS does not open filing when ready on January 1

The IRS must process millions of returns filed in the prior tax year before it can safely open the new season. Returns filed in December and early January are still being processed, and the IRS needs to close out those accounts before opening new ones. If the IRS opened filing too early, it could create errors where new returns are matched to the wrong taxpayer account or where prior-year refunds are delayed.

The IRS also coordinates with tax software companies to test their systems against the IRS computers. Tax software must be certified to work with the IRS before filing opens, and this testing takes several weeks. The IRS publishes testing requirements and timelines on its website for software developers.

What you can do before filing opens

You can gather documents and organize your information before the IRS opens filing. Collect W-2 forms from your employers, 1099 forms for other income, receipts for deductions you plan to claim, and records of estimated tax payments you made during the year. If you received unemployment benefits, student loan interest statements, or charitable donation receipts, gather those too.

You can also read tax software or set up an account with a tax preparation service before filing opens. Most software will let you enter your information and preview your return before you submit it. You just cannot transmit the return to the IRS until after the filing season opens.

If you are waiting for a specific form—such as a Schedule K-1 from a partnership or S corporation—you may need to wait until after filing opens to complete your return. These forms are often issued later than W-2s and 1099s, and the IRS allows filers to submit returns without them if they are not yet available, then file an amended return later.

How filing early affects your refund timeline

If you are due a refund, filing as soon as the season opens can speed up when you receive it. The IRS processes returns in the order they are received, so an early filing means your return moves through the queue sooner. The IRS typically issues refunds within 21 days of accepting your return, though some refunds take longer if the return requires review or if you claim certain credits.

Filing electronically is faster than mailing a paper return. Electronic returns are received and processed when ready, while paper returns must be opened, scanned, and entered into the system by hand. If you are expecting a refund and want it as soon as possible, e-filing is the better choice.

State filing important date and opening dates

Most states open their filing season on the same day as the IRS or within a few days. However, some states have different rules. A few states do not have an income tax, so there is no state return to file. Others allow filing to open earlier than the federal date.

Check your state's tax agency website for the opening date and any state-specific rules. Some states require you to file by April 15 even if the federal important date is extended, while others follow the federal important date exactly. State websites usually post this information by December.

What happens if you file after the important date

The federal tax important date is usually April 15, though it can shift to April 16 or 17 if April 15 falls on a weekend or holiday. If you file after April 15 without an extension, you owe a failure-to-file penalty on top of any taxes owed. The penalty is usually 5 percent of unpaid taxes for each month the return is late, up to 25 percent.

If you cannot file by April 15, you can request an automatic extension from the IRS. An extension gives you until October 15 to file your return, though you still owe any taxes due by April 15. The extension only delays filing, not payment.

Frequently Asked Questions

Can I file my taxes before January 29, 2025?

No. The IRS will not accept any federal returns before the filing season opens. Tax software will reject the submission, and paper returns will be returned by mail. You can prepare your return and gather documents before the opening date, but you cannot submit it to the IRS.

Do I have to file on the first day the season opens?

No. You can file anytime between the opening date and April 15 (or the extended important date if you request one). Filing early can speed up a refund, but there is no penalty for filing later in the season as long as you file by the important date.

What if my state opens filing before the IRS does?

Some states do open a few days before the federal season. You can file your state return early if your state allows it, but you still cannot file your federal return until the IRS opens. You may need to file state and federal returns on different dates.

Does the filing opening date change every year?

Yes. The IRS sets a new opening date each year, usually in late January or early February. The exact date depends on when the IRS finishes testing systems and processing prior-year returns. The IRS announces the date in December of the prior year.

What if I owe taxes instead of getting a refund?

You still cannot file before the season opens. Once filing opens, you can file your return and arrange payment. If you owe taxes, you must pay by April 15 even if you file earlier. You can set up a payment plan with the IRS if you cannot pay the full amount by the important date.
