The IRS typically begins accepting returns in late January

The IRS opens its filing season in late January most years, though the exact date shifts slightly from year to year. For the 2024 tax year, the IRS began accepting returns on January 29, 2024. For 2025 returns, filing opened on January 27, 2025. The IRS announces the opening date several months in advance, so you can plan around it.

The delay between the end of the calendar year (December 31) and the opening of filing season exists because employers, banks, and other institutions need time to send you the documents you need — your W-2 forms, 1099s, mortgage interest statements, and others. The IRS waits until most of these documents are in circulation before opening the system to prevent you from filing incomplete returns.

You can prepare your return before the IRS opens for filing. Many people gather documents and use tax software to draft their return in January, then submit it the moment the system goes live. This approach lets you file early and receive a refund sooner if one is due to you.

Key Takeaways

  • The IRS opens for filing in late January each year, with the exact date announced months in advance.
  • The delay allows time for employers and financial institutions to send you the tax documents you need to file accurately.
  • You can prepare your return before filing season opens, then submit it as soon as the IRS system accepts returns.
  • Filing early in the season can speed up refund processing if you are due money back.
  • The filing deadline remains April 15 regardless of when the season opens, unless that date falls on a weekend or holiday.

Why the IRS doesn't open immediately after New Year's

Tax documents arrive on a staggered schedule. Your employer must send your W-2 by January 31, but many send them earlier. Banks and investment firms send 1099 forms (for interest, dividends, and other income) by the same deadline. Mortgage companies send 1098 forms showing interest paid. State tax agencies send information about state income tax refunds. The IRS waits until the bulk of these documents are in the mail before opening filing.

If the IRS opened immediately on January 1, you would file without these documents and likely have to amend your return later when they arrived. That creates extra work for you and for the IRS. By waiting until late January, the agency ensures most people have what they need to file once.

How to prepare before filing season opens

Gather your documents as they arrive. Keep W-2s, 1099s, mortgage statements, and charitable donation records in one place. If you are self-employed or have business income, organize your income and expense records now rather than waiting until you file.

You can enter information into tax software before the IRS opens for filing. Most major tax software platforms let you build your return in draft form, review it, and save it. Once the IRS opens, you simply review the draft one more time and submit. This approach means you are ready to file within minutes of the system going live, which can matter if you are expecting a refund.

If you use a tax professional or accountant, you can meet with them in January to review your situation and gather what they need. Many professionals begin preparing returns in January and file them the moment the IRS opens.

Filing early versus filing at the last minute

Filing early has one clear advantage: if you are due a refund, you receive it sooner. The IRS typically processes refunds within 21 days of receiving your return, though it can take longer during peak season. If you file in late January, you might have your refund by mid-February. If you file in April, you might wait until May or June.

Filing early also reduces the risk of identity theft. Tax fraud happens when someone files a false return in your name to claim a refund. If you file first, the fraudulent return will be rejected. If you wait until April, a thief might file before you do.

The only reason to delay filing is if you need more time to gather documents or if you expect to owe money and want to hold onto cash longer. Even then, remember that the deadline is April 15 (or the next business day if that falls on a weekend). Filing on April 14 still counts as on time, but filing on April 16 results in penalties and interest.

What happens if you file before the season officially opens

If you submit a return before the IRS opens for filing, the system will reject it. You will receive an error message telling you to resubmit once filing season has begun. Your return is not lost — you simply need to file it again after the opening date.

This is why most people wait for the official opening date rather than trying to file early. Tax software will usually prevent you from submitting before the IRS is ready, but if you use a tax professional, they will hold your return and file it on opening day.

The filing deadline doesn't change with the opening date

No matter when the IRS opens for filing, the deadline to file remains April 15 of the following year (or April 16 or 17 if April 15 falls on a weekend or a federal holiday). Opening late in January does not extend the deadline. You have roughly 2.5 months from opening day to file.

If you cannot file by April 15, you can request an extension from the IRS. An extension gives you until October 15 to file your return, but it does not extend the deadline to pay taxes owed. If you owe money, you still owe it by April 15 even if you have an extension to file.

Frequently Asked Questions

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

No. If you submit a return before the IRS opens for filing, it will be rejected. You will need to resubmit once the system is accepting returns. Most tax software will prevent you from submitting early, and tax professionals typically hold returns and file them on opening day.

What if I don't have all my documents by the time filing opens?

You can file without some documents and amend your return later when they arrive. However, this creates extra work. A better approach is to wait a few days after filing opens to give late documents time to arrive, or contact the issuer directly if a document is overdue.

Does filing early mean I'll get my refund faster?

Yes. The IRS typically processes refunds within 21 days of receiving your return, though this can take longer during peak season. Filing in late January means you could receive a refund by mid-February, while filing in April might mean waiting until May or June.

What if April 15 falls on a weekend?

The deadline moves to the next business day. If April 15 is a Saturday, the deadline becomes Monday, April 17. If it is a Sunday, the deadline becomes Monday, April 16. The IRS announces the exact deadline each year.

Can I file my return on April 14 and still be on time?

Yes. Any return filed on or before April 15 (or the next business day) is considered on time. Filing on April 14 is perfectly fine. Filing on April 16 results in late-filing penalties and interest, even if you are due a refund.
