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 finishes testing its systems and when certain tax forms are ready. For the 2024 tax year (returns filed in 2025), the IRS started accepting returns on January 27, 2025. The agency announces the opening date in the fall of the previous year, so you can plan ahead.

Filing early has real advantages. The sooner you file, the sooner you receive a refund if you are owed one. If you are expecting a refund, filing in late January or February means you could see the money within two to three weeks. Waiting until April means a longer wait, even though the important date is April 15. Early filing also reduces the chance that someone else files a fraudulent return using your Social Security number.

Key Takeaways

  • The IRS opens its filing season in late January or early February each year, with the exact date announced in the fall.
  • You can file your return as soon as the IRS begins accepting them, even if your employer has not yet sent your W-2 form.
  • Filing early increases your chances of receiving a refund quickly and reduces identity theft risk.
  • The tax important date remains April 15 regardless of when the filing season opens, but filing later leaves less time to resolve problems.
  • Tax software and tax professionals can often file your return before the IRS officially opens if you have all your documents ready.

Why the filing season does not open on January 1

The IRS does not open filing season on January 1 because employers and financial institutions need time to prepare and mail tax documents. Your employer must send you a W-2 form, banks must send 1099 forms for interest and dividends, and brokerages must send forms for investment income. The IRS has set January 31 as the important date for most employers to mail W-2s, which is why the agency waits until late January to open filing.

The IRS also uses the delay to test its systems and make sure they can handle millions of returns without crashing. The agency runs security checks and updates its software to catch fraud and errors. This testing period typically takes two to three weeks, which is why you see the filing season open in late January rather than early January.

What you can do before the filing season opens

You do not have to wait for the IRS to open filing season to prepare. Gather your documents as soon as you receive them: W-2s from your employer, 1099s from banks and investment firms, receipts for deductible expenses, and records of charitable donations. If you are self-employed, organize your income and expense records. Having everything ready means you can file within hours of the IRS opening its doors.

You can also meet with a tax professional or use tax software before the filing season opens. Many tax professionals will prepare your return in advance and hold it until the IRS is ready to receive it. Tax software companies often let you enter your information and review your return before filing it. This approach saves time on the actual filing day and gives you a chance to catch errors or missing information.

Filing before you receive all your documents

You can file your return before you receive every document, but you may need to file an amended return later. If your employer is late sending your W-2, you can file using your last pay stub and the income information your employer provided during the year. The IRS will match your return against the W-2 when it arrives, and if the numbers do not match, the IRS will contact you. You can then file an amended return to correct the discrepancy.

This approach works best if you are expecting a refund, because filing early starts the refund process. If you owe taxes, waiting for all your documents reduces the risk of underpaying and owing penalties. If you are unsure whether you have everything, a tax professional can review your documents and advise you on whether it is safe to file.

The difference between filing season opening and the tax important date

The date the IRS opens filing season is not the same as the tax important date. The filing season opening is when the IRS begins accepting returns. The tax important date is April 15 (or the next business day if April 15 falls on a weekend or holiday). You have from late January through April 15 to file your return for that tax year.

Filing before April 15 does not change your important date or your obligations. You still owe the same taxes whether you file in February or April. The main reason to file early is to receive a refund sooner and to reduce fraud risk. If you owe taxes, filing early gives you more time to arrange payment and avoid penalties for late payment.

What happens if you miss the April 15 important date

If you do not file by April 15, you can request an automatic extension that gives you until October 15 to file. You must request the extension before April 15 — you cannot wait until after the important date. Filing for an extension does not extend the important date for paying taxes you owe; you still owe payment by April 15 even if you file your return later. If you owe taxes and do not pay by April 15, you will owe penalties and interest on the unpaid amount.

If you are expecting a refund, there is no penalty for filing late, but you will not receive your refund until you file. The IRS will not send you a refund automatically. If you file more than three years after the important date, the IRS may keep any refund you are owed.

How to find the exact filing season opening date

The IRS announces the filing season opening date on its official website, irs.gov, in the fall of the previous year. You can also call the IRS at 1-800-829-1040 to ask when filing season opens. Tax software companies and tax professionals will also have the date posted on their websites and will notify you when they are ready to file returns.

The IRS also publishes a tax calendar that shows important dates throughout the year, including the filing season opening date, quarterly estimated tax payment important date, and the final tax important date. You can find the tax calendar on irs.gov by searching for "tax calendar" or asking a tax professional for a copy.

Frequently Asked Questions

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

Some tax software and tax professionals will prepare your return before the IRS opens, but they cannot submit it to the IRS until the filing season officially begins. You can have your return ready to go on day one of filing season, which means it will be processed faster than if you wait until March or April.

What if my employer has not sent my W-2 by the time filing season opens?

You can file using your last pay stub or the income information your employer provided during the year. When your W-2 arrives, the IRS will match it against your return. If the numbers match, nothing happens. If they do not match, the IRS will contact you and you may need to file an amended return.

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

No. You can file anytime between when the IRS opens filing season and April 15. Filing early is usually better because you receive refunds sooner and reduce fraud risk, but there is no requirement to file on the first day.

What happens if I file after April 15?

If you do not file by April 15, you can request an extension that moves your important date to October 15. You must request the extension before April 15. If you owe taxes and do not pay by April 15, you will owe penalties and interest on the unpaid amount, even if you file your return later.

Where can I find the exact filing season opening date for next year?

The IRS announces the filing season opening date on irs.gov in the fall of the previous year. You can also call the IRS at 1-800-829-1040 or check with a tax professional or tax software company for the date.
