When the IRS Starts Accepting Tax Returns Each Year

The IRS filing season typically opens in late January

The IRS usually begins accepting tax returns in late January or early February each year. The exact date shifts slightly because the IRS needs time after the new year to update its systems and test them with real returns. For the 2024 tax year, the IRS started accepting returns on January 29. For 2025, the start date is January 27.

The opening date matters because returns filed before the IRS is ready to receive them will be rejected by tax software and professional preparers. Even if you finish your return in early January, you cannot submit it until the IRS announces it is ready. The IRS publishes the opening date on its website and through tax software companies several weeks in advance.

Filing season runs from the opening date through April 15 (or the next business day if April 15 falls on a weekend). This gives you roughly 2.5 to 3 months to file. If you owe taxes, filing early means you pay sooner. If you are owed a refund, filing early means you receive it sooner — typically within 21 days if you file electronically and choose direct deposit.

Why the IRS does not open earlier in January

The delay exists because employers and financial institutions must send you documents — W-2s from your employer, 1099s from banks and investment firms, and other income records — by January 31. The IRS cannot process your return accurately until it receives these documents and loads them into its system. If the IRS opened in early January, most returns would be incomplete or incorrect.

The IRS also uses the time between January 1 and late January to update its computer systems, test them with sample returns, and prepare for the volume of returns it will receive. This testing period catches errors before they affect millions of taxpayers. Once the IRS announces the opening date, tax software companies and professional tax preparers also run their own tests to make sure they can submit returns correctly.

How to find the exact opening date each year

The IRS publishes the opening date for the upcoming filing season on IRS.gov, usually in November or December of the prior year. You can search for "IRS filing season" or "when does tax season start" on the IRS website to find the current year's date. Major tax software companies — TurboTax, H&R Block, TaxAct, and others — also display the opening date prominently when you log in during January.

If you use a tax professional or CPA, they will know the opening date and will not let you file before the IRS is ready. If you prepare your own return using software, the software will prevent you from submitting until the IRS is accepting returns. Attempting to file before the opening date will straightforward result in an error message.

What happens if you file before the IRS opens

If you try to file electronically before the IRS opens, your tax software will reject the return with an error message. The software is programmed to block submissions until the IRS announces it is ready. You will need to wait until the opening date to resubmit.

If you mail a paper return before the opening date, the IRS will still receive it and process it once the filing season begins. Paper returns are date-stamped by the post office, so filing early by mail does not create a problem — the IRS straightforward processes it in the order it arrives after the season opens. However, mailing early does not speed up processing, since the IRS does not begin reviewing paper returns until after the opening date.

important date and penalties if you miss April 15

April 15 is the final important date to file your return and pay any taxes owed, unless you receive an extension. If you do not file by April 15 and do not have an extension, you owe a failure-to-file penalty of 5 percent of your unpaid taxes for each month the return is late, up to 25 percent total. If you owe taxes and do not pay by April 15, you also owe interest and a failure-to-pay penalty.

If you are owed a refund, there is no penalty for filing late — but you cannot receive your refund until you file. The IRS will hold your refund indefinitely if you never file. If you are unsure whether you owe or are owed a refund, filing early removes the risk of a penalty.

You can request a six-month extension by filing Form 4868 before April 15. An extension moves your important date to October 15 but does not extend the important date to pay taxes owed. If you owe, you must estimate the amount and pay it by April 15 to avoid interest and penalties, even if your return is not due until October.

Why filing early is usually better than waiting

Filing as soon as the IRS opens gives you the longest window to catch errors, respond to IRS notices, and receive your refund. If the IRS finds a mistake on your return, it will contact you — but the sooner you file, the sooner any issue can be resolved before the April 15 important date.

If you are owed a refund, filing early means you receive your money sooner. Direct deposit refunds typically arrive within 21 days of the IRS accepting your return. If you wait until March or April to file, you may not receive your refund until late May or June.

Filing early also reduces the risk of identity theft. Tax-related identity theft happens when someone files a fraudulent return using your Social Security number before you file your legitimate return. The IRS processes the first return it receives. Filing early protects you by ensuring your legitimate return is processed first.

What to have ready before filing season opens

Gather your W-2s, 1099s, and other income documents as soon as they arrive in January. 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. If you own a business or have rental income, organize receipts and records of expenses.

If you received unemployment benefits, student loan interest payments, or made charitable donations, have those documents ready. If you are itemizing deductions instead of taking the standard deduction, organize receipts for medical expenses, property taxes, mortgage interest, and other deductible items. Having everything organized before the filing season opens means you can file when ready once the IRS is ready.

Frequently Asked Questions

Can I file my taxes before the IRS opens?

No. Tax software will reject your return if you try to submit it before the IRS announces it is ready. You can prepare your return in advance, but you cannot submit it electronically until the opening date. Paper returns can be mailed early, but the IRS will not process them until after the season opens.

What if I miss the April 15 important date?

You owe a failure-to-file penalty of 5 percent of unpaid taxes for each month late, plus interest. You can avoid the penalty by filing Form 4868 before April 15 to request a six-month extension, moving your important date to October 15. However, you must still pay any taxes owed by April 15 to avoid additional penalties.

How long does it take to get a refund after I file?

The IRS typically processes electronic returns and issues refunds within 21 days if you choose direct deposit. Paper returns take much longer — often six to eight weeks or more. Filing early in the season does not speed up processing, but it ensures you receive your refund before the summer.

Do I have to file if I do not owe taxes?

If you are owed a refund, you should file to receive it. The IRS will not send you a refund unless you file a return. If you do not owe and are not owed a refund, you are not required to file, but filing does not hurt.

Where do I find the exact opening date for next year?

The IRS publishes the opening date on IRS.gov in November or December of the prior year. You can also check your tax software or call the IRS at 1-800-829-1040. Tax professionals and preparers will also have the date available.
