The IRS typically opens its filing season in late January or early February

The IRS does not accept tax returns before a specific date each year, even if you have all your documents ready. The agency sets an official start date — usually in late January or the first week of February — and will reject any return filed before that date. For the 2024 tax year (returns filed in 2025), the IRS began accepting returns on January 27, 2025. The exact date shifts slightly year to year because the IRS coordinates with state tax agencies and needs time to update its systems after the previous year closes.

The opening date applies to all filing methods: paper returns, e-file through a tax professional, and self-filed returns through tax software. If you submit electronically before the official date, your return will be rejected and you will need to resubmit it. If you mail a paper return before the date, it will be processed when received, but the IRS will not begin processing it until after the season opens.

Key Takeaways

  • The IRS announces its opening date in November or December of the prior year, so you can plan ahead rather than guess.
  • Filing before the official date will result in rejection if you e-file, or delayed processing if you mail a paper return.
  • The opening date is the same for all filers — there is no early access for certain income types or filing statuses.
  • State tax agencies often open on the same date as the IRS, though a few states open earlier or later depending on their own schedules.
  • The IRS typically closes its filing season on April 15, though extensions can push your important date to October 15 if you request one.

Why the IRS does not open when ready after December 31

The delay between the end of the tax year and the opening of filing season exists because the IRS needs time to reprogram its systems, coordinate with state agencies, and may support that employers and financial institutions have submitted the documents you need. Form W-2s from employers and Form 1099s from banks and brokers are due to the IRS by January 31, so the agency waits until after that important date to begin accepting returns. This timing reduces the chance that you will file a return based on incomplete information.

The IRS also uses the gap to update tax software providers, test its systems, and train staff. If the opening date falls on a weekend or federal holiday, the IRS moves it to the next business day. For example, if January 27 is a Saturday, the season opens on Monday, January 29.

How to find the exact opening date for your tax year

The IRS publishes its filing season opening date on its official website, IRS.gov, in November or December of the prior year. You can search for "IRS filing season" or "when does tax season open" on that site to find the announcement. The date is also listed on the IRS's social media accounts and in press releases.

If you work with a tax professional — a CPA, enrolled agent, or tax preparer — they will know the opening date and will not file your return before it. If you use tax software, the software will not allow you to e-file before the official date; it will show an error message instead. Do not assume the date based on prior years, because it does shift. Verify the date for the current year before you gather your documents and sit down to file.

What happens if you file before the season opens

If you attempt to e-file before the IRS opens, your return will be rejected with an error message. You will then need to resubmit it after the opening date. This rejection does not count as a failed filing attempt or trigger any penalty — it is straightforward a timing issue. Your tax software or preparer will guide you to resubmit once the date arrives.

If you mail a paper return before the opening date, the IRS will receive it and hold it until the season opens, then process it in the order received. Mailing early does not speed up your refund; it only means your return sits in a queue. The postmark date is what matters for the April 15 important date, so mailing in early January is fine from a important date perspective — it just will not be processed until after the season opens.

State tax return important date and opening dates

Most states open their tax filing season on the same date as the IRS, but not all. Some states open a few days earlier or later. A handful of states — including Illinois and a few others — do not have a state income tax, so there is no state return to file. If you live in a state with income tax, check your state's tax agency website in November or December to confirm when it will begin accepting returns.

If your state opens before the IRS, you can file your state return early and then file your federal return once the IRS season opens. If your state opens after the IRS, you can file federal first and state later. There is no requirement to file both on the same day.

Planning ahead: what to do before the season opens

Gather your documents now rather than waiting until the season opens. You will need your prior year's tax return, your Social Security number or ITIN, your spouse's information if filing jointly, and all income documents: W-2s, 1099s, K-1s, and any other forms showing income. You will also need records of deductions if you itemize — mortgage interest statements, property tax records, charitable donation receipts — or documentation of any credits you plan to claim.

If you are working with a tax professional, contact them in December or early January to schedule an appointment. Many preparers book up quickly once the season opens, and scheduling early ensures you get a time slot before April. If you plan to e-file yourself, read or purchase your tax software in advance so you can review it and become familiar with it before you need to file.

What to do if you need your refund quickly

Filing on the first day the IRS opens does not speed up your refund significantly. The IRS processes returns in the order received, and even early filers typically wait three to five weeks for a refund if they e-file and choose direct deposit. If you file by mail, the wait is longer — often six to eight weeks or more.

The fastest way to receive a refund is to e-file your return and request direct deposit to your bank account. Avoid claiming a refund anticipation loan, which charges fees and does not actually speed up the IRS's processing. If you need cash before your refund arrives, explore other options — a short-term loan, a line of credit, or a payment plan with creditors — rather than paying fees to a tax preparer for a loan against your refund.

Frequently Asked Questions

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

No. If you e-file before the official opening date, your return will be rejected. If you mail a paper return, it will be received but not processed until after the season opens. There is no way to file successfully before the IRS's announced date.

Does filing on the first day of tax season get me a faster refund?

Not significantly. The IRS processes returns in the order received, and early filers typically wait three to five weeks for a refund via direct deposit. Filing a few days or weeks later will not change your refund timeline much. Accuracy and completeness matter more than speed.

What if I do not have all my documents by the time the season opens?

You can file without some documents if you have a reasonable estimate — for example, if your W-2 is delayed, you can estimate your wages based on recent pay stubs and amend later. However, waiting until you have all documents reduces the chance of errors and the need to file an amended return. The important date is April 15, so you have time to wait.

Do I have to file my state and federal returns on the same day?

No. You can file federal and state returns on different dates. If your state opens before the IRS, file state first. If the IRS opens first, file federal first. There is no penalty for filing them separately or on different days.

Where can I find the exact opening date for this year?

Visit IRS.gov and search for "filing season" or check the IRS's press releases in November or December. Your tax preparer or software provider will also have the date. Do not assume it based on prior years — verify the current year's date before you file.
