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

The Internal Revenue Service (IRS) opens its filing system on January 29, 2025, and that is the earliest date you can submit your 2024 return to the federal government. You cannot file before that date, even if you have all your documents ready. The filing window stays open through April 15, 2025, which is the deadline for most people.

This timing applies to federal returns. Some states open their filing systems on different dates, though most align with the federal start date. If you file through a tax software company or a tax preparer, they may let you prepare your return before January 29, but they cannot transmit it to the IRS until that date.

The IRS staggered the opening date to give itself time to process the previous year's returns and update its systems. This also spreads out the volume of returns hitting the agency at once, which reduces processing delays.

Key Takeaways

  • You cannot file your 2024 federal return before January 29, 2025, no matter how early you have your documents.
  • The deadline to file is April 15, 2025, unless you request an extension or live in a state with a different deadline.
  • You can prepare your return in tax software before January 29, but it will not transmit to the IRS until that date or later.
  • W-2 forms from employers and 1099 forms from other income sources must reach you by January 31, 2025.
  • Filing early can speed up your refund if you are owed money, since the IRS processes returns in the order they arrive.

Why the IRS does not open filing until late January

The IRS needs time after the calendar year ends to prepare its systems and receive documents from employers and financial institutions. Employers must send W-2 forms to workers by January 31, and banks and investment firms must send 1099 forms by the same date. The IRS cannot safely process returns before it has received and verified these documents.

Opening on January 29 gives the IRS a two-day buffer before the January 31 document deadline. In practice, some documents arrive late, and the IRS accounts for this by accepting amended returns and corrected forms throughout the year. But the official filing window does not open until the agency has had time to test its systems and prepare for the volume of returns.

What you need before January 29

Gather your income documents as they arrive. For most people, this means your W-2 from your employer, which you should receive by January 31. If you have other income — from a side job, rental property, investments, or self-employment — you will receive a 1099 form for each source, also by January 31.

You will also need records of deductions or credits you plan to claim. This includes receipts for charitable donations, mortgage interest statements, property tax records, student loan interest statements, and childcare expenses. If you are claiming the Earned Income Tax Credit (EITC) or the Child Tax Credit, have your Social Security numbers and birth dates for all dependents ready.

If you received unemployment benefits, a 1099-G form will show the amount. If you received a distribution from a retirement account, you will get a 1099-R. The specific forms depend on your situation, but the rule is the same: they arrive by January 31.

Filing early versus waiting until April

If you expect a refund, filing as soon as the window opens — around late January or early February — means the IRS will process your return sooner and send your refund sooner. The IRS processes returns in the order they arrive, so an early filer typically receives a refund within 21 days of the IRS accepting the return. A filer who waits until March or April will wait longer for the same refund.

If you owe taxes, there is no advantage to filing early. You do not owe the money until April 15, and filing early just means you pay sooner. However, if you cannot pay the full amount by April 15, filing early gives you more time to set up a payment plan with the IRS.

If you are unsure whether you will owe or receive a refund, you can file as soon as you have your documents. The IRS will calculate the result and either send you a refund or bill you for what you owe.

What happens if you file before January 29

If you submit your return to the IRS before January 29, the agency will reject it. Tax software and tax preparers are programmed to block transmission before the official opening date, so you will get an error message rather than a successful submission.

You can prepare your return in advance — most tax software lets you do this — but the software will hold it and transmit it automatically on or after January 29. Some software lets you choose the transmission date; others send it as soon as the window opens. Check your software's settings if you want to control the timing.

State tax filing dates and deadlines

Most states that have an income tax follow the federal filing window and deadline. They open around January 29 and close on April 15. A few states have different dates, though this is rare.

If you file federal taxes through a tax software company, the software usually handles state returns at the same time. You will see the state filing date when you set up your return. If you use a tax preparer, they will file both federal and state returns together unless you ask otherwise.

Some states do not have an income tax — these include Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming. If you live in one of these states, you only file federal taxes.

Frequently Asked Questions

Can I file my 2024 taxes in December 2024?

No. The IRS does not accept 2024 returns until January 29, 2025. If you submit a return before that date, it will be rejected. You can prepare your return in tax software in December, but it will not transmit to the IRS until the filing window opens.

What if I do not receive my W-2 by January 31?

Contact your employer and ask them to send it. If they do not send it by January 31, you can file your return using an estimate of your income and file an amended return later when the W-2 arrives. The IRS also has a process for reporting missing W-2s, though this delays your return. It is better to follow up with your employer directly.

Does filing on January 29 may provide a faster refund?

Filing on January 29 gives you the earliest possible position in the processing queue, which usually means a faster refund. However, the IRS processes returns in batches, and refunds can take 21 days or longer depending on the complexity of your return and the IRS's workload. Filing early improves your odds but does not may provide a specific date.

What if April 15 falls on a weekend or holiday?

If April 15 is a Saturday or Sunday, the deadline moves to the following Monday. If it falls on a federal holiday, the deadline moves to the next business day. For 2025, April 15 is a Tuesday, so the deadline is April 15. Check the IRS website each year to confirm the exact deadline for your state.

Can I file my 2024 return after April 15?

You can file after April 15, but you will owe a failure-to-file penalty if you owe taxes. If you expect a refund, there is no penalty for filing late, but you lose the refund if you do not file within three years. The safest approach is to file by April 15 or request an extension before that date.
