The IRS opens filing for 2025 taxes on January 24, 2025

The Internal Revenue Service begins accepting and processing 2025 tax returns on January 24, 2025. This is the official start date each year — before this date, tax software will reject your return and the IRS will not process it, even if you file electronically.

The January 24 start date applies to all filing methods: paper returns mailed to the IRS, e-filed returns through tax software, and returns filed through a tax professional. If you mail a paper return before January 24, it will sit in the IRS mailroom unprocessed until after that date.

The IRS sets this date each year to allow time for W-2s, 1099s, and other income documents to reach both taxpayers and the agency. Employers and financial institutions have until January 31 to send W-2 and 1099 forms to workers and the IRS, so the January 24 start gives the IRS a small window to receive and load those documents into their system before processing begins.

Key Takeaways

  • January 24, 2025 is the first day the IRS will accept 2025 tax returns through any method — paper, e-file, or tax professional.
  • Filing before January 24 will not work; tax software will reject your return and the IRS will not process paper returns received early.
  • W-2s and 1099s do not have to arrive in your mailbox before you file, but the IRS waits until January 24 to allow employers and financial institutions time to send them.
  • If you file on January 24 or shortly after, expect your refund within 21 days if you chose direct deposit and had no errors on your return.

Why the IRS does not open earlier

The January 24 start date exists because employers, banks, investment firms, and other payers must send income documents to both you and the IRS by January 31. The IRS needs time to receive and process millions of W-2s and 1099s before it can match them against the returns you file.

If you filed before those documents reached the IRS, your return would not match the income records the agency has on file. This mismatch would trigger a notice months later asking you to explain the difference, even if your return was correct. By waiting until January 24, the IRS reduces these mismatches and speeds up processing overall.

Some income documents arrive late — a few employers miss the January 31 deadline, and the IRS accepts late W-2s and 1099s throughout the year. But the agency cannot delay opening for everyone because of late filers. January 24 is a compromise: early enough that most people can file within a few days, late enough that the vast majority of income documents have arrived.

What to do if you do not have all your documents by January 24

You do not have to wait for every document to arrive before you file. If you have received most of your W-2s and 1099s by late January, you can file with what you have. The IRS expects some documents to arrive after you file.

If you are missing a W-2 from an employer, contact the employer's payroll or human resources department and ask them to send it or provide a copy. If they cannot, you can file without it and amend your return later once it arrives. If you are missing a 1099 from a bank or brokerage, log into your account online — most financial institutions post 1099s in your account before mailing them.

Do not guess at income amounts or leave fields blank hoping to fill them in later. Report what you know, and if a document arrives after you file showing different income, you will receive a notice from the IRS. You can then file an amended return (Form 1040-X) to correct it. This is normal and happens to thousands of filers each year.

How fast you will get your refund if you file early

If you file within the first week of January 24 and chose direct deposit on your return, the IRS typically issues your refund within 21 days. This 21-day window is the IRS's standard processing time for returns with no errors or missing information.

The speed depends on three things: whether you chose direct deposit (faster than a check), whether your return had any errors, and whether the IRS needs to verify any information. If you filed electronically, chose direct deposit, and your return matches your income documents, 21 days is realistic. If you mailed a paper return or chose a check, add 2 to 4 weeks.

The IRS does not process returns in the order they arrive. Instead, it runs returns through automated checks, then sends some to human reviewers if something looks unusual. A return filed on January 24 might be processed before one filed on February 1 if the later return needs manual review.

Filing before January 24 through a tax professional or employer

Some tax professionals and payroll services offer to file your return before January 24 using a process called "return preparation" — they prepare it, store it, and submit it the moment the IRS opens. This is legal and does not violate any rule.

However, the IRS still will not process it until January 24 or later. The only advantage is that your return is ready to go the instant the filing window opens, so you do not have to wait for the tax professional to prepare it after January 24. If you are working with a tax professional, ask whether they offer this service and whether there is an extra fee.

Some employers offer to prepare and file your taxes as a benefit. The same rule applies: they can prepare it early, but the IRS will not accept it until January 24.

What happens if you file after the April 15 deadline

April 15, 2025 is the deadline to file your 2025 tax return. If you owe taxes and do not file by April 15, you will owe a failure-to-file penalty on top of the taxes owed, plus interest. If you are due a refund, there is no penalty for filing late, but you will lose the refund if you do not file within three years.

If you cannot file by April 15, you can request an automatic extension from the IRS. Filing Form 4868 (Application for Automatic Extension of Time To File U.S. Individual Income Tax Return) gives you until October 15, 2025 to file. The extension gives you more time to file, but it does not extend the time to pay taxes owed — if you owe, you should pay by April 15 anyway to avoid interest and penalties.

Frequently Asked Questions

Can I file my 2025 taxes in December 2024?

No. Tax software will reject your return, and the IRS will not process it. The earliest you can file is January 24, 2025. If you want to prepare your return early, most tax software lets you save a draft, but you cannot submit it until after January 24.

Do I need to wait for my W-2 to arrive in the mail before I file?

No. You can file as soon as January 24 even if your W-2 has not arrived. Most employers post W-2s online before mailing them. Log into your employer's payroll portal or ask payroll for a copy. If it has not arrived by late January, you can file with your best estimate and amend later if needed.

What if I file on January 24 and my refund does not arrive in 21 days?

Check the IRS website using the "Where's My Refund?" tool with your Social Security number and refund amount. This tool shows the real status of your return. If the IRS is still processing it, the tool will tell you. If there is an error or missing information, the IRS will send you a notice by mail.

Is there a penalty for filing before January 24 if I somehow manage to do it?

No penalty, but the IRS simply will not accept it. Your return will be rejected by the software or the IRS mailroom, and you will have to resubmit it after January 24. There is no fine for trying.

Can I file my 2024 taxes and 2025 taxes at the same time?

Yes. If you have not yet filed your 2024 return, you can file both 2024 and 2025 returns after January 24, 2025. File the 2024 return first, then the 2025 return. The IRS processes them separately, but there is no rule against filing both in the same tax season.
