The IRS opens its filing season in late January or early February each year

The IRS does not accept tax returns on January 1st. Filing season typically begins in late January or early February, though the exact date shifts slightly from year to year. The 2024 season opened on January 29. For 2025, the IRS announced it will begin accepting returns on January 27. The agency sets this date each fall and publishes it on IRS.gov.

The delay exists because the IRS needs time after the calendar year ends to receive final documents from employers, banks, and other institutions. Your W-2 forms, 1099s, and other income statements are not due to you until January 31st. The IRS waits a few weeks after that important date to let stragglers arrive before opening the system to millions of filers at once.

You can prepare your return before filing season opens—gather documents, use tax software to draft it, or meet with a tax preparer. But you cannot submit it to the IRS until the season officially begins. If you try to file early, the IRS will reject it.

Key Takeaways

  • The IRS opens its filing season in late January or early February each year, not on January 1st.
  • The exact opening date is announced in the fall and published on IRS.gov; for 2025 it is January 27.
  • The delay allows time for W-2s, 1099s, and other income documents to reach the IRS from employers and financial institutions.
  • You can prepare your return before filing season opens, but the IRS will reject any submission filed before the official start date.
  • Filing early in the season reduces the risk of identity theft and gives the IRS more time to process your return before the April important date.

Why the IRS does not open on January 1st

The IRS receives millions of documents from employers, banks, investment firms, and other sources. Your employer must send you a W-2 by January 31st. If you received unemployment benefits, a 1099-U will arrive by that date. Interest income, dividends, and other earnings come on 1099 forms with the same important date. The IRS itself does not receive these documents until after January 31st, and processing them all takes weeks.

If the IRS opened filing season on January 1st, most people would not yet have the documents they need to file accurately. The agency would also face a massive surge of incomplete or incorrect returns, which slows processing for everyone. By waiting until late January or early February, the IRS ensures that most filers have their documents in hand and can submit accurate returns.

How to find the exact opening date for this year

The IRS publishes the filing season opening date on its official website, IRS.gov, in the fall of the previous year. You can search "IRS filing season" or look for the annual announcement on the homepage. The date is also listed on the IRS's social media accounts and in press releases.

Tax software companies and tax preparation services also announce the opening date as soon as the IRS does. If you use TurboTax, H&R Block, TaxAct, or another platform, you will see the date prominently displayed when you log in during the off-season. Your tax preparer will also know the date and can tell you when to expect to file.

What happens if you try to file before the season opens

If you submit your return to the IRS before filing season officially begins, the IRS system will reject it automatically. The rejection is not an error—it is by design. The IRS does not process returns outside the official filing window.

You can still file with a tax preparer or use tax software to prepare your return before the season opens. The software will let you draft, review, and save your return. But when you click "submit" or "file," the system will either refuse to send it or will hold it until the IRS opens. Some software platforms let you schedule your return to submit automatically on the first day of filing season.

The important date to file is April 15th, regardless of when you start

Filing season opens in late January or early February, but the important date to file your return is always April 15th (or the next business day if April 15th falls on a weekend or holiday). This gives you roughly 2.5 to 3 months to file.

Filing early has real advantages. The sooner you file, the sooner you receive a refund if you are owed one. Early filers also reduce their risk of identity theft, because a thief cannot file a fraudulent return in your name if you have already filed. The IRS processes returns in the order they are received, so filing in late January or early February means your return moves through the queue faster than one filed in March or April.

What to do while you wait for filing season to open

Gather your documents now. Collect your W-2 from your employer, any 1099 forms from banks or investment accounts, mortgage interest statements, property tax records, and receipts for deductible expenses. If you are self-employed, organize your income and expense records. Having everything ready means you can file within days of the season opening.

If you use a tax preparer, schedule your appointment early. Many preparers book up quickly once filing season begins. Meeting in late January or early February ensures you get a time slot and can file promptly. If you use tax software, read it and create an account before the season opens so you are ready to start the moment the IRS accepts returns.

State filing seasons may open on different dates

Most states follow the federal IRS schedule and open their filing season on the same date. However, some states open a few days earlier or later. A few states do not have an income tax at all, so there is no state filing season.

Check your state's tax agency website to confirm the opening date for state returns. If your state opens before the IRS, you can file your state return first and then file your federal return once the IRS season begins. If your state opens after the IRS, file federal first and state second.

Frequently Asked Questions

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

You can prepare your return before filing season opens, but you cannot submit it to the IRS. Tax software will let you draft and save your return, and some platforms allow you to schedule it to submit automatically on the first day of the season. A tax preparer can also prepare your return in advance.

What happens if I file after April 15th?

If you owe taxes, you will owe penalties and interest on the unpaid amount starting April 16th. If you are owed a refund, there is no penalty for filing late, but you lose the refund if you do not file within three years. Filing an extension gives you until October 15th to submit your return, though you still owe any taxes due by April 15th.

Why does the filing season opening date change every year?

The IRS adjusts the opening date based on when January 31st falls and how long the agency needs to process incoming documents from employers and financial institutions. The date typically falls between January 24th and February 4th, but the exact day shifts year to year.

Do I need to wait for filing season to open to meet with a tax preparer?

No. You can meet with a tax preparer before filing season opens to gather information, organize documents, and discuss your tax situation. The preparer will prepare your return and file it as soon as the IRS opens for the season.
