The IRS filing season typically opens in late January

The IRS usually begins receiving tax returns in late January or early February each year. The exact date shifts slightly from year to year because it depends on when the IRS completes its systems testing and when January 31st falls on a weekday. For the 2024 tax year, the IRS started accepting returns on January 29, 2024. For 2025 tax returns, the IRS began accepting on January 27, 2025.

The opening date matters because the IRS processes returns in the order they arrive. If you file early in the season, your return moves through the queue faster, and if you are owed a refund, you receive it sooner. The IRS does not hold early returns and process them all at once — they work through the stack continuously from the moment filing opens.

You can file before the official opening date using tax software or a tax professional, but the IRS will not receive your return until after that date. Some software programs let you prepare your return early and schedule it to transmit automatically on opening day, which can be useful if you want to be among the first filers.

Key Takeaways

  • The IRS opens its filing season in late January, usually between January 27 and February 4, and the exact date changes each year.
  • Returns filed earlier in the season are processed faster, so filing in February or early March usually means a quicker refund than filing in April.
  • You can prepare your return before the opening date using tax software or a tax professional, but it will not transmit to the IRS until after filing season opens.
  • The IRS processes returns continuously from opening day through the April 15 deadline, not in batches, so timing affects how long your return sits in the queue.

Why the IRS does not open earlier

The IRS needs time after the end of the calendar year to prepare its systems and test them. Tax forms change from year to year, employers and financial institutions send updated information to the IRS, and the agency must update its computers to handle new rules or changes to tax law. This testing period typically runs through most of January.

The IRS also coordinates its opening date with state tax agencies, many of which open their filing seasons on the same day or shortly after. A staggered opening across federal and state systems helps prevent the computer overload that would happen if millions of people tried to file everywhere at once.

What happens if you file before the season opens

If you submit your return to the IRS before the official opening date, the IRS will reject it. Your tax software or tax professional will receive an error message, and your return will not enter the IRS system. You will need to resubmit it after the filing season opens.

Some tax software allows you to prepare your return completely and then schedule it to file automatically on opening day. This is a legitimate way to be among the first filers without manually resubmitting. Check your software's settings to see if it offers this feature.

How filing early affects your refund timeline

The IRS typically issues refunds within 21 days of receiving your return, but that timeline assumes your return has no errors and does not require additional review. Returns filed in late January or early February usually receive refunds by mid-February or early March. Returns filed in March or April face longer waits because they enter a larger queue.

If you are owed a refund and you file by early February, you are likely to receive it before mid-March. If you wait until late March or April, the same return might not be refunded until May or June, even though the processing time is the same. The difference is purely the position in the queue.

Returns that trigger additional review — such as those claiming the Earned Income Tax Credit, the Child Tax Credit, or certain business deductions — take longer regardless of when you file. The IRS is required by law to hold these returns for a minimum period before issuing a refund, usually until mid-February at the earliest.

Filing after April 15 if you miss the deadline

If you do not file by April 15, you can still file after that date, but you will owe penalties and interest on any taxes you owe. The IRS charges a failure-to-file penalty of 5 percent per month (or part of a month) of the unpaid tax, up to 25 percent total. If you are owed a refund, there is no penalty for filing late, but you have only three years from the original deadline to claim that refund.

If you cannot file by April 15, you can request an automatic extension from the IRS, which gives you until October 15 to file without penalty. An extension does not extend the deadline to pay taxes you owe — you still owe payment by April 15 — but it does extend the filing deadline itself.

State tax filing seasons and deadlines

Most states open their tax filing seasons on the same day as the IRS or within a few days. A few states do not have income tax, so there is no state return to file. If you live in a state with income tax, you will typically file both your federal return and your state return around the same time using similar information.

State filing deadlines usually match the federal deadline of April 15, though some states set their own dates. Check your state's tax agency website to confirm the opening date and deadline for your state, as they can differ from the federal dates.

Frequently Asked Questions

Can I file my taxes before the IRS opens its filing season?

You can prepare your return before the season opens, but the IRS will reject it if you try to submit it early. Some tax software lets you schedule your return to file automatically on opening day. Otherwise, you must wait until after the official opening date to submit.

What is the difference between filing in January versus April?

Both returns are processed the same way, but filing in late January or early February means your return enters a shorter queue and is processed faster. A return filed in April enters a much longer queue and waits longer for processing, even though the actual processing time is the same. If you are owed a refund, filing early means receiving it sooner.

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

No, but filing in early February is significantly faster than filing in late March or April. You do not need to file on the exact opening day, but filing within the first two weeks of the season puts you ahead of the majority of filers. Filing in the last week before April 15 means a much longer wait.

What happens if I file after April 15?

If you owe taxes, you will owe penalties and interest on the unpaid amount. If you are owed a refund, there is no penalty, but you have only three years from April 15 to claim it. You can request an automatic extension to October 15 to file without penalty, though you still owe any taxes due by April 15.

Does the IRS filing season opening date change every year?

Yes, the opening date shifts slightly each year because it depends on when the IRS finishes testing its systems and when January 31st falls. The opening date is usually between January 27 and February 4. The IRS announces the opening date in December of the prior year.
