The IRS typically opens its filing season in late January

The IRS begins receiving tax returns in late January or early February each year. The exact date shifts slightly year to year — it depends on when the agency finishes testing its systems and when the IRS and tax software companies coordinate their readiness. For the 2024 tax year (returns filed in 2025), the IRS started receiving returns on January 27, 2025. The agency announces the opening date in the fall of the previous year, so you can plan ahead.

You can file your return as soon as you have all your documents, even if the IRS hasn't officially opened yet. However, the IRS will not process it until after the filing season officially begins. If you file early, your return sits in a queue. This matters most if you're expecting a refund — filing early means your refund arrives earlier, since processing begins on the official start date.

The filing deadline is April 15 each year, unless that date falls on a weekend or holiday. If April 15 is a Saturday or Sunday, the deadline moves to Monday. If it's a federal holiday, the deadline moves to the next business day. You can request an automatic extension to October 15, but this only extends your filing deadline — taxes owed are still due by April 15.

Why the IRS doesn't open immediately after January 1

The IRS needs time to update its systems for the new tax year. Tax laws change annually — standard deduction amounts shift, tax brackets adjust for inflation, and new forms or schedules may be required. The agency also coordinates with tax software companies, employers, and financial institutions to ensure all systems can communicate correctly when processing begins.

The IRS also uses this time to test its infrastructure. The volume of returns filed in the first few weeks is enormous, and the agency stress-tests its systems to handle that load without crashing. If problems are discovered during testing, the opening date may be delayed. This happened in 2023 when a cyberattack forced a delay, though such events are rare.

What happens when you file before the official opening

Tax software and the IRS both accept early filings. Your return is transmitted to the IRS immediately, but it enters a holding queue. The IRS does not begin processing these returns until the official filing season opens. This means your return sits unprocessed for days or weeks, depending on how early you filed.

If you're owed a refund, this delay matters. The IRS processes returns in the order they were received, starting on the official opening date. Filing on January 15 means your return is first in line; filing on January 27 means it's processed alongside thousands of others filed that same day. The difference can be one to three weeks in when you receive your refund.

If you owe taxes, filing early has no downside — you're not required to pay until April 15 anyway. However, if you're paying electronically, the payment itself must be scheduled for April 15 or earlier; you cannot pay before you file.

How to find the exact opening date for the current year

The IRS publishes the filing season opening date on its official website, IRS.gov, in the fall of the previous year. You can search "IRS filing season opening date" or visit the IRS newsroom. The agency also announces the date through press releases and updates its homepage when the season is about to begin.

Tax software companies also display the opening date prominently when you log in during January. If you're using TurboTax, H&R Block, TaxAct, or another major platform, the software will tell you whether the IRS is currently accepting returns. This is the most reliable way to check if you're ready to file.

What to do if you file before the opening date

If you file before the IRS officially opens, keep a copy of your filed return and the confirmation number. The IRS will send you an acknowledgment email or letter once your return is received, but this may take several days. Do not file again — filing the same return twice creates confusion and delays processing.

If you need to make changes after filing but before the IRS opens, you can file an amended return (Form 1040-X) once the season begins. However, if the IRS hasn't processed your original return yet, you may be able to withdraw it and file a corrected version instead. Contact the IRS or your tax software provider for guidance on your specific situation.

Refund timing after the IRS opens

Once the IRS begins processing returns on the official opening date, refunds typically arrive within 21 days for most filers. This timeline assumes your return is complete, accurate, and filed electronically. Paper returns take longer — usually six to eight weeks.

The IRS processes returns in batches, so the exact timing depends on when your return is processed within that batch. Filing on the opening day does not may provide a refund within 21 days; it means your return enters the processing queue first. If your return requires additional review — for example, if you claimed the Earned Income Tax Credit — processing takes longer.

You can track your refund status using the IRS "Where's My Refund?" tool on IRS.gov. This tool updates once per day and shows whether your return has been received, is being processed, or has been approved for refund.

Extensions and late filing

If you cannot file by April 15, you can request an automatic extension by filing Form 4868. This moves your filing deadline to October 15 but does not extend your payment deadline. If you owe taxes, they are due April 15 even if you file an extension. Paying late results in penalties and interest.

Filing an extension is free and can be done electronically through tax software or by mailing Form 4868 to the IRS. You must request the extension by April 15 — you cannot file it after the deadline has passed. If you file your return after October 15 without an extension, the IRS assesses a failure-to-file penalty in addition to any taxes owed.

Frequently Asked Questions

Can I file my taxes before the IRS opens for the season?

Yes, you can file before the official opening date. Tax software accepts your return immediately, and it is transmitted to the IRS. However, the IRS will not process it until after the filing season officially begins. If you expect a refund, filing early means it arrives sooner since processing starts on the opening date.

What if I file early and need to make changes?

If you filed before the IRS opened and need to correct something, you can file an amended return (Form 1040-X) once the season begins. If the IRS hasn't processed your original return yet, you may be able to withdraw it and file a corrected version instead. Contact the IRS or your tax software for guidance on your situation.

Does filing an extension give me more time to pay taxes I owe?

No. An extension (Form 4868) moves your filing deadline to October 15, but taxes owed are still due April 15. If you owe money, pay by April 15 to avoid penalties and interest, even if you file an extension.

How do I know when my refund will arrive?

Most refunds arrive within 21 days of the IRS processing your return, if you filed electronically. Paper returns take six to eight weeks. Use the IRS "Where's My Refund?" tool on IRS.gov to check your status — it updates once per day and shows whether your return has been received, is being processed, or has been approved.

What happens if I file after April 15 without an extension?

The IRS assesses a failure-to-file penalty on top of any taxes owed, plus interest on unpaid taxes. The penalty is typically 5% of unpaid taxes per month, up to 25%. Filing an extension by April 15 prevents this penalty, even if you file your actual return after October 15.
