The IRS began accepting 2024 returns on January 27, 2025

The IRS opens its filing season on a set date each year, and for the 2024 tax year, that date was January 27, 2025. This is when the agency's systems go live to receive returns from taxpayers and tax professionals. You can file as soon as that date arrives — there is no advantage to waiting, and filing early can mean a refund reaches your account weeks sooner.

The filing season runs through April 15, 2025, which is the deadline for most taxpayers. If you cannot file by that date, you can request an automatic extension that moves your deadline to October 15, 2025. The extension gives you more time to file, but it does not extend the deadline to pay any taxes you owe — those are still due on April 15.

Key Takeaways

  • The IRS began accepting 2024 returns on January 27, 2025, and you can file immediately after that date.
  • The standard filing deadline is April 15, 2025, and filing early can speed up your refund by several weeks.
  • If you need more time, you can file Form 4868 to request an automatic extension that moves your deadline to October 15, 2025.
  • An extension delays your filing deadline but not your payment deadline — taxes owed are still due April 15 unless you have a separate hardship reason.

Why the IRS opens on a specific date each year

The IRS does not accept returns before its official opening date because the agency needs time to update its systems with new tax laws, forms, and procedures for the year. Tax code changes, inflation adjustments, and new filing requirements all take effect on January 1, but the IRS systems that process returns take weeks to build and test. Opening too early would mean rejecting returns that do not match the current year's rules.

The opening date also gives tax software companies and tax professionals time to update their systems. Most major software providers — TurboTax, H&R Block, TaxAct, and others — release their 2024 versions around the same time the IRS opens, so you can file through those platforms as soon as January 27.

How to file as soon as the season opens

If you want to file immediately, you have three main routes. You can use tax software on your computer or phone, work with a tax professional in person or by video, or file by mail. Tax software is the fastest option for most people — you enter your information, the software calculates your refund or payment, and you submit electronically within minutes. The IRS processes electronic returns much faster than paper returns, often depositing refunds within 21 days.

If you use a tax professional, they can file your return as soon as they have all your documents. Many professionals begin scheduling appointments in early January so they can file on opening day for clients who are ready. If you file by mail, your return takes longer to process — the IRS estimates 4 to 6 weeks for paper returns, and you lose the speed advantage of filing early.

What documents you need before filing

You cannot file until you have the documents that show your income for the year. For W-2 employees, that is your W-2 form from each employer. For self-employed people, you need records of all income and business expenses. If you have investment income, rental income, or other sources, you need the corresponding 1099 forms or statements.

Most employers and financial institutions mail W-2s and 1099s by January 31, so you may not have everything by January 27. If you are missing documents, you can wait to file, or you can file with the information you have and amend later if needed. The IRS allows you to file without a W-2 if your employer has not sent it yet — you can use your pay stubs or last paystub of the year as a substitute, then file an amended return if the W-2 shows different numbers.

Filing early versus waiting until later

Filing early has real advantages. If you are owed a refund, filing in late January or early February means the IRS can deposit it by mid-February or early March. If you wait until March or April, your refund arrives later in the year. If you owe taxes, filing early gives you more time to arrange payment before the April 15 deadline.

The only reason to wait is if you do not yet have all your documents or if you are still gathering receipts for deductions. If you are itemizing deductions instead of taking the standard deduction, you may need time to organize charitable donations, medical expenses, or property tax records. But if you have your W-2s and basic income documents, there is no benefit to waiting.

What to do if you cannot file by April 15

If you cannot file by the April 15 deadline, you can request an automatic extension by filing Form 4868. You do not need a reason — the extension is automatic if you file the form before April 15. The form is simple: it asks for your name, address, and estimated tax liability. You can file it electronically through tax software, by mail, or through a tax professional.

Filing Form 4868 moves your filing deadline to October 15, 2025, but it does not move your payment deadline. If you owe taxes, they are still due April 15. If you cannot pay by then, you can request a payment plan or other relief, but filing the extension form alone does not protect you from penalties and interest on unpaid taxes. If you are owed a refund, the extension does not affect you — there is no penalty for filing a refund return late.

Common reasons people file late

Some people file after April 15 because they owe money and want to delay payment. This creates penalties and interest that grow each month. If you know you owe, filing early and setting up a payment plan with the IRS is cheaper than waiting. Other people file late because they are disorganized or procrastinate, which also costs them in penalties.

Others file late because they have a complicated return — multiple income sources, business income, rental property, or significant deductions. If your situation is complex, working with a tax professional in February or March gives you time to gather documents and plan your return without rushing. A professional can also spot deductions or credits you might miss, which can save you money and reduce the chance of an audit.

Frequently Asked Questions

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

No. The IRS does not accept 2024 returns before January 27, 2025. If you try to file through tax software or a professional before that date, the system will reject it. You can prepare your return ahead of time, but you cannot submit it until the filing season opens.

What happens if I file after April 15?

If you owe taxes and file after April 15 without an extension, you owe penalties and interest on the unpaid amount. If you are owed a refund, there is no penalty for filing late, but you lose the refund if you do not file within three years. Filing an extension form before April 15 moves your deadline to October 15 and protects you from failure-to-file penalties.

Do I have to file on opening day to get my refund faster?

Filing on opening day is not necessary, but filing in January or February does mean your refund arrives sooner than if you file in March or April. The IRS processes returns in the order it receives them, so earlier filing generally means earlier refund. If you are owed a refund, there is no penalty for waiting, but you do get your money faster by filing early.

Can I file my return if I have not received my W-2 yet?

Yes. If your employer has not sent your W-2 by January 31, you can file using your last paystub or pay stubs from the year. The IRS will match your return against the W-2 when it arrives. If the numbers differ, you may need to file an amended return, but you can file now and correct it later if needed.
