The IRS began accepting 2024 tax returns on January 27, 2025

The IRS opened its filing season for 2024 returns on Monday, January 27, 2025. This is the official start date when the agency begins processing returns filed electronically or by mail. If you file before this date, the IRS will not process your return — it will be held until the filing season opens, which can delay any refund you are owed.

The filing deadline itself is April 15, 2025. You have until midnight on that date to file your return or request an extension. Filing early does not speed up processing time significantly, but it does reduce the window during which identity theft or fraud could occur using your information.

Key Takeaways

  • The IRS began accepting 2024 returns on January 27, 2025, and will not process returns filed before that date.
  • The deadline to file is April 15, 2025, unless you request an extension, which gives you until October 15, 2025.
  • E-filed returns are processed faster than paper returns, typically within 21 days if there are no issues.
  • If you are owed a refund, filing early can get money into your account sooner, though the IRS cannot issue most refunds before mid-February 2025.

Why the IRS does not accept returns before January 27

The IRS waits until late January to open filing season because employers and financial institutions need time to send out tax documents. Your employer must send you a W-2 by January 31, and banks must send 1099 forms for interest and dividends by the same date. The IRS sets the filing season start date to give people time to receive these documents and gather the information needed to file accurately.

Filing before you have all your documents in hand often means filing an incomplete or incorrect return. You can amend it later, but that creates extra work and delays any refund. The IRS's January 27 start date is designed to align with when most people will have the paperwork they need.

How long the IRS takes to process returns

If you file electronically and your return has no errors or missing information, the IRS typically processes it within 21 days. This is the standard timeframe the agency publishes. However, the IRS cannot issue most refunds before mid-February 2025, even if your return is processed sooner. This delay is intentional — the agency uses the time to verify information and prevent fraud.

Paper returns take much longer. The IRS estimates six to eight weeks for a mailed return to be processed, partly because staff must manually enter the information. If you are expecting a refund, filing electronically is significantly faster than mailing a paper return.

What happens if you file after April 15

If you do not file by April 15, 2025, and do not request an extension, you will owe a failure-to-file penalty on top of any taxes you owe. The penalty is typically 5 percent of the unpaid tax for each month your return is late, up to 25 percent total. You will also owe interest on any unpaid taxes, calculated daily from the original due date.

If you cannot file by April 15, you can request an automatic extension using Form 4868. This gives you until October 15, 2025, to file your return. The extension applies only to filing — you still owe any taxes due by April 15, or you will owe penalties and interest on the unpaid amount. You can pay an estimate of what you owe when you request the extension to avoid these charges.

How to file your 2024 return

You have three main options: file electronically through IRS-approved software, use a tax professional, or file by mail. Electronic filing is the fastest and most accurate method. The IRS Free File program offers free tax software to people who earn less than a certain amount — that threshold varies by year, so check the IRS website for 2024 income limits.

If you use a tax professional, they will file electronically on your behalf. If you file by mail, send your return to the address listed in the instructions for your form — the address depends on your state and whether you are including a payment. Keep a copy for your records and consider using certified mail so you have proof the IRS received it.

Refund timing and direct deposit

The fastest way to receive a refund is to file electronically and choose direct deposit. The IRS will deposit your refund directly into your bank account rather than mailing a check. Even with direct deposit, most refunds do not arrive before mid-February 2025 because of the IRS's fraud-prevention review process.

You can track your refund using the IRS's "Where's My Refund?" tool on the IRS website. This tool updates once a day and shows the status of your return and when your refund will be issued. If your refund is delayed beyond the normal timeframe, this tool will tell you why.

Common reasons the IRS delays processing

The IRS holds returns for review if there are math errors, missing information, or inconsistencies with documents they have on file. If your return claims a large refund, the IRS may take extra time to verify the information. Returns claiming the Earned Income Tax Credit (EITC) or the Additional Child Tax Credit are also reviewed more carefully, which can add weeks to processing time.

Identity theft and fraud detection also cause delays. If the IRS suspects someone filed a return using your Social Security number, they will hold your return while they investigate. You will receive a letter explaining the delay and what information you need to provide. This process can take several weeks or longer.

Frequently Asked Questions

Can I file my 2024 return before January 27, 2025?

You can prepare your return and submit it to tax software or a tax professional before January 27, but the IRS will not process it until the filing season opens. Your return will be held and processed starting January 27. There is no advantage to filing before the season opens.

What if I do not have all my tax documents by January 27?

You can file your return without all documents if you have the main ones, such as your W-2. If you are missing a 1099 form, you can file based on the information you have and amend your return later when the document arrives. However, this creates extra work and may delay your refund.

Do I have to file electronically, or can I mail my return?

You can file by mail, but paper returns take six to eight weeks to process compared to 21 days for electronic returns. If you are expecting a refund, mailing your return will delay it significantly. Electronic filing is faster and more reliable.

What if I owe taxes instead of getting a refund?

You still need to file by April 15, 2025. If you owe taxes, you can pay when you file or set up a payment plan with the IRS. Paying by the deadline avoids penalties and interest. If you cannot pay the full amount, the IRS offers installment agreements that let you pay over time.

Can I request an extension if I am not ready to file?

Yes. File Form 4868 by April 15, 2025, to get an automatic six-month extension until October 15, 2025. The extension gives you more time to file your return, but you still owe any taxes due by April 15. Pay an estimate of what you owe with the extension to avoid penalties and interest on the unpaid amount.
