The IRS begins accepting returns on January 29, 2025

The Internal Revenue Service will start accepting and processing 2024 tax returns on Wednesday, January 29, 2025. This is the official start date each year, and it applies whether you file electronically or by mail. The IRS does not accept returns before this date, even if your tax software is ready or your documents are complete.

The delay between the end of the tax year (December 31) and the start of filing season gives the IRS time to update systems, test software, and prepare for the volume of returns. It also gives employers and financial institutions time to send you the forms you need — W-2s, 1099s, and other income documents — which are due to reach you by January 31.

If you file before January 29, the IRS will reject your return. If you mail a paper return that arrives before that date, it will be held and processed starting January 29. There is no advantage to submitting early, and doing so only delays your refund.

Key Takeaways

  • The IRS will not accept any 2024 tax returns before January 29, 2025, regardless of how you file.
  • Employers and financial institutions must send you W-2s and 1099s by January 31, so waiting until late January to file gives you time to receive all your documents.
  • Filing electronically is faster than mailing a paper return, and refunds typically arrive within 21 days of acceptance if you choose direct deposit.
  • The IRS processes returns in the order they are received after January 29, so filing on the first day does not speed up your refund.

Why the IRS waits until late January to open filing season

The IRS needs time to reprogram its systems for the new tax year, update tax tables, and incorporate any law changes that took effect. The agency also coordinates with employers, banks, and other institutions to ensure they have sent out all the forms taxpayers need to file accurately.

W-2 forms from employers and 1099 forms from banks, investment firms, and other payers are due to reach you by January 31. If the IRS opened filing season earlier, many people would file incomplete returns and then have to amend them later when the missing forms arrived. Starting on January 29 gives most filers time to receive their documents before they file.

How to prepare before filing season opens

Gather your documents now so you are ready to file as soon as January 29 arrives. You will need your Social Security number, date of birth, and filing status. If you are claiming dependents, have their Social Security numbers and dates of birth ready.

Collect income documents as they arrive: W-2s from employers, 1099-INT from banks (for interest), 1099-DIV from investment accounts (for dividends), 1099-MISC or 1099-NEC from clients or side work, and mortgage interest statements (Form 1098) if you own a home. If you received unemployment benefits, student loan interest statements, or education credits, gather those forms too.

If you paid state and local taxes, property taxes, or made charitable donations, keep records of those amounts. You will need them to claim deductions if you itemize rather than take the standard deduction.

Electronic filing versus mailing a paper return

Filing electronically is faster and more reliable. The IRS accepts e-filed returns immediately after January 29, processes them within 24 hours, and sends refunds within 21 days if you choose direct deposit to a bank account. Paper returns take longer: the IRS must receive them, open the envelope, scan the documents, and enter the data, which can take several weeks or months.

You can file electronically through tax software (paid or free), a tax professional, or the IRS Free File program if your income is below a certain threshold. The IRS Free File program offers free federal return preparation and filing through participating software companies. Check IRS.gov to see if you meet the income limits.

If you must mail a paper return, send it early enough that it arrives by the April 15 deadline. The postmark date is what counts, not the arrival date, so mailing by April 15 protects you even if the IRS receives it later.

What happens if you file before January 29

If you submit an electronic return before January 29, the IRS will reject it with an error message. Your tax software will tell you the return was rejected and will not let you resubmit until after January 29. You will then have to file again once the IRS opens for the season.

If you mail a paper return that arrives before January 29, the IRS will hold it and begin processing it on January 29 along with all other returns received that day. There is no penalty for mailing early, but your return will not be processed any faster than one mailed on January 29 itself.

Timeline for refunds after you file

If you file electronically and choose direct deposit, the IRS typically issues your refund within 21 days of accepting your return. If you request a check by mail, add another week or two for postal delivery. Some refunds take longer if the IRS needs to verify information or if your return is selected for review.

The IRS processes returns in the order they are received, so filing on January 29 does not give you a faster refund than filing in February or March. The 21-day timeline starts from the date the IRS accepts your return, not from the date you submit it.

You can check the status of your refund using the IRS Where's My Refund tool on IRS.gov. This tool updates once a day and will tell you whether the IRS has received your return, is processing it, or has issued your refund.

Frequently Asked Questions

Can I file my 2024 return in December 2024?

No. The IRS will not accept any 2024 returns before January 29, 2025. If you try to file electronically, your software will reject the return. If you mail a paper return in December, the IRS will hold it and process it starting January 29.

What if I have not received my W-2 by January 29?

You can file without it if you know your income amount, but you risk errors. If your W-2 arrives later and shows different income, you may owe money or have to amend your return. Contact your employer if you have not received a W-2 by February 1 — they are required to send it by January 31.

Does filing on January 29 get me a faster refund?

No. The IRS processes returns in the order received, and refunds typically take 21 days from acceptance regardless of when you file. Filing in early February will not meaningfully delay your refund compared to filing on the first day.

What if I owe taxes instead of getting a refund?

You can file as soon as January 29 and pay what you owe immediately, or you can wait until closer to April 15. If you cannot pay in full, the IRS offers payment plans. Filing early does not change your deadline — taxes are due April 15, 2025.

Can I file my 2024 return after April 15, 2025?

You can file late, but you will owe penalties and interest on any taxes owed. If you are expecting a refund, there is no penalty for filing late, but you lose the refund if you do not file within three years. File by April 15 to avoid complications.
