The IRS began accepting 2024 tax returns on January 29, 2025

The IRS opened its filing season on January 29, 2025, and will continue accepting returns through April 15, 2025. This date marks when the agency's systems are ready to receive and process returns for the 2024 tax year. You can file electronically through tax software, a tax professional, or by mail, though electronic filing is faster and more reliable.

The IRS does not process returns before this date, even if you submit them earlier. If you mail a return before January 29, the IRS will hold it and process it once the season officially opens. Electronic returns submitted before the season opens will be rejected and you'll need to resubmit.

Key Takeaways

  • The 2024 tax filing season runs from January 29, 2025, through April 15, 2025.
  • Filing electronically is faster than mailing and reduces errors that delay processing.
  • Returns submitted before January 29 will be rejected if filed electronically or held if mailed.
  • The IRS typically issues refunds within 21 days of accepting an electronic return, though some take longer.
  • If you owe taxes, filing early gives you more time to arrange payment before the April 15 deadline.

Why the IRS doesn't open earlier

The IRS needs time to update its systems with new tax laws, forms, and procedures that took effect in the new year. The agency also coordinates with employers and financial institutions to ensure W-2s, 1099s, and other documents are ready for distribution. These documents typically arrive in late January, and the IRS waits until most are in circulation before opening the filing season.

Starting the season on a consistent date also gives tax professionals and software companies time to prepare their systems. Tax software must be tested and certified to work with IRS systems before the season opens, which takes several weeks of development and quality checks.

Electronic filing versus mailing your return

Electronic filing is the fastest way to get your return processed. The IRS accepts e-filed returns 24 hours a day, seven days a week during filing season. Once accepted, your return is typically processed within 21 days, though refunds can take longer depending on your bank and whether the IRS needs to verify information on your return.

Mailing a paper return takes longer because the IRS must receive it, open it, scan it into the system, and then process it. A mailed return typically takes four to six weeks to process, and refunds take even longer. If you mail your return, send it early in the season to avoid delays from high mail volume in March and April.

You can file electronically through IRS-approved tax software (many offer free versions if your income is below a certain threshold), through a tax professional, or through the IRS Free File program if you meet income requirements. The IRS website lists all approved software and providers.

What to have ready before filing

Gather your W-2s from all employers, 1099s for interest or investment income, and records of deductions or credits you plan to claim. If you're claiming dependents, have their Social Security numbers and birth dates. If you're claiming education credits, have your 1098-T forms from your school. For itemized deductions, collect receipts for medical expenses, property taxes, mortgage interest, and charitable donations.

If you received unemployment benefits in 2024, you'll need the 1099-U form. If you received a third stimulus payment or advance child tax credit payments, have those records as well. Having everything organized before you start filing reduces errors and speeds up processing.

Refund timing and direct deposit

The IRS issues most refunds within 21 days of accepting your return if you file electronically and request direct deposit. Direct deposit is the fastest method—the IRS transfers your refund directly to your bank account. If you request a paper check, the refund takes longer because the IRS must print and mail it.

Some refunds take longer than 21 days. The IRS may need to verify information on your return, especially if you claim certain credits or deductions. If your return is flagged for review, the IRS will contact you by mail. Do not contact the IRS about your refund before 21 days have passed; the agency cannot speed up processing.

You can track your refund status using the IRS Where's My Refund tool on the IRS website. This tool updates once daily and shows whether your return has been received, is being processed, or has been approved for refund.

Filing early versus filing close to the deadline

Filing early in the season has advantages. Your return is processed faster because the IRS has fewer returns in the queue. If you're owed a refund, you receive it sooner. If you owe taxes, filing early gives you time to arrange payment or set up a payment plan before April 15.

Filing close to the deadline increases the risk of errors and missed deadlines. Tax software may experience slowdowns from high volume. If you mail your return, it may not arrive before April 15 if there are postal delays. If you discover an error after filing, you have less time to correct it before the deadline passes.

What happens if you miss the April 15 deadline

If you do not file by April 15, 2025, you may owe penalties and interest on any taxes you owe. The failure-to-file penalty is typically 5 percent of unpaid taxes for each month your return is late, up to 25 percent. Interest accrues daily on unpaid taxes at a rate set by the IRS each quarter.

If you are owed a refund, there is no penalty for filing late, but you lose the ability to claim that refund after three years. If you need more time, you can request an automatic extension by filing Form 4868 before April 15. An extension gives you until October 15, 2025, to file, but does not extend the deadline to pay taxes you owe—those are still due April 15.

Frequently Asked Questions

Can I file my 2024 return before January 29, 2025?

No. The IRS will not accept 2024 returns before January 29. If you try to file electronically before that date, your return will be rejected. If you mail it early, the IRS will hold it and process it once the season opens.

What if I don't have all my documents by January 29?

You can file without some documents if you have the main ones (W-2s, 1099s). However, if you're missing forms you need to claim deductions or credits, you may want to wait until you receive them. You can also file and then amend your return later if you find you missed something.

How do I know if my return was received by the IRS?

If you filed electronically, you'll receive an acknowledgment from the software or tax professional within 24 hours confirming receipt. You can also use the IRS Where's My Refund tool to check the status. If you mailed your return, there's no immediate confirmation, so keep a copy for your records.

Is there a penalty if I file after April 15?

If you owe taxes and file late, you'll owe penalties and interest. If you're owed a refund, there's no penalty, but you cannot claim the refund after three years from the filing deadline. Filing an extension form before April 15 gives you until October 15 to file without penalty.

Can I file my return on April 15 if it falls on a weekend?

In 2025, April 15 is a Tuesday, so that is the deadline. If April 15 falls on a weekend or holiday in other years, the deadline moves to the next business day. The IRS website announces the exact deadline each year.
