The IRS opens tax filing in late January for most people

The IRS typically opens the filing season in late January or early February each year. For the 2024 tax year (filed in 2025), the IRS began accepting returns on January 24, 2025. The exact date shifts slightly year to year because the IRS needs time to update its systems and process forms from employers and financial institutions.

You cannot file before this date, even if you have all your documents ready. The IRS's computers will reject early returns. However, you can prepare your return and gather your paperwork weeks in advance — you just cannot submit it until the filing season officially opens.

The important date to file is April 15 of the following year, though this date can shift if April 15 falls on a weekend or holiday. You have roughly 2.5 months from the opening of filing season to submit your return.

Key Takeaways

  • Tax filing season opens in late January or early February each year, and you cannot file before the IRS announces the official start date.
  • You can gather documents and prepare your return before filing season opens, but submission will be rejected if you try to file early.
  • The filing important date is April 15 unless that date falls on a weekend or federal holiday, in which case it moves to the next business day.
  • If you need more time, you can request an extension that pushes the important date to October 15, though taxes owed are still due by April 15.
  • The IRS opens filing season late to allow employers and banks time to send W-2s, 1099s, and other income documents to both you and the IRS.

Why the IRS waits until late January to open filing

The delay exists because employers, banks, and other institutions must send you copies of income documents before the IRS can process returns accurately. Your employer must send your W-2 by January 31. Banks and investment firms must send 1099s (forms showing interest, dividends, or other income) by the same date. The IRS itself receives copies of these documents from employers and financial institutions, and the agency needs time to match them against returns you file.

If you filed before these documents arrived, your return might be incomplete or incorrect. The IRS would then have to contact you to correct it, creating delays for everyone. By waiting until late January, the IRS ensures that most people have received their documents and can file accurately the first time.

What you can do before filing season opens

You can start gathering documents as soon as you receive them. Collect your W-2s from employers, 1099s from banks and investment accounts, mortgage interest statements (Form 1098), student loan interest statements, and receipts for deductible expenses. If you are self-employed, organize your income records and business expenses.

You can also use tax software or work with a tax preparer before filing season opens. Many software programs let you enter information and prepare a draft return. You straightforward cannot submit it to the IRS until the filing season officially begins. Some people find this helpful because it lets them identify missing documents or questions before they try to file.

How to know the exact filing season start date

The IRS announces the filing season start date on its website (irs.gov) in December, before the year ends. You can also check the IRS's social media accounts or sign up for email updates from the agency. Tax software companies and tax preparation services also announce the date prominently when it is released.

Do not rely on guesses or past years' dates. The opening date varies slightly, and filing a day or two early can cause your return to be rejected. Wait for the official announcement, which is always available on irs.gov by mid-December.

Filing early in the season versus waiting until April

Filing early has advantages. If you are due a refund, you receive it sooner — sometimes within a few weeks if you choose direct deposit. Filing early also means you finish before the rush, so if you work with a tax preparer, you may get faster service and avoid the April crunch.

Filing closer to April 15 has no real advantage unless you are still waiting for a document or expecting additional income. The only reason to wait is if your financial situation is still changing. Otherwise, filing in February or March is simpler and faster.

What to do if you need more time

You can request an extension that moves your filing important date to October 15. This is called an automatic extension because you do not need the IRS's permission — you straightforward file Form 4868 before April 15. However, an extension only delays when you must file your return. It does not delay when taxes are due.

If you owe taxes, you still must pay by April 15, even if you have an extension. Paying late results in interest and penalties. An extension is useful if you need more time to gather documents or work with a preparer, but it does not help you avoid paying what you owe on time.

Special situations that affect when you can file

If you are waiting for a corrected or amended document from an employer or financial institution, you may need to file after you receive it. For example, if your employer sends you a corrected W-2 in February, you can file once you have the corrected version. The IRS understands these delays and does not penalize you for filing after April 15 if you are correcting an error caused by the other party.

If you are a U.S. citizen or resident alien living abroad, you automatically get an extension until June 15 to file, though taxes are still due by April 15. Military members stationed overseas also receive this extension. These are the only situations where the filing important date itself moves; in all other cases, April 15 is the important date.

Frequently Asked Questions

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

No. The IRS's systems will reject any return filed before the official filing season start date, which is announced in December and typically falls in late January or early February. You can prepare your return in advance, but you cannot submit it until the IRS opens for the year.

What happens if I file too early?

Your return will be rejected by the IRS's computer system. You will need to resubmit it after the filing season officially opens. This does not result in a penalty, but it does delay processing and any refund you might receive.

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

No. You can file anytime between the opening date and April 15. Filing early can speed up refunds, but there is no penalty for waiting until March or early April. The only important date that matters is April 15 (or October 15 if you request an extension).

If I file an extension, do I still have to pay taxes by April 15?

Yes. An extension delays when you must file your return, not when you must pay. If you owe taxes, you must pay by April 15 even if you have an extension to file. Unpaid taxes after April 15 result in interest and penalties.

What if my W-2 or 1099 arrives after filing season opens?

You can file your return once you receive the document. If you have already filed without it, you can file an amended return (Form 1040-X) after you receive the missing document. The IRS expects some documents to arrive late and does not penalize you for amending a return to include them.
