The IRS opens the 2025 tax filing season on January 27, 2025

You can begin filing your 2025 tax return on January 27, 2025. This is the official start date the IRS sets each year — before this date, the agency will not accept returns, even if you have all your documents ready. The filing season runs through April 15, 2025, which is the important date to file or request an extension.

Starting your return before January 27 means preparing documents and organizing information, but you cannot actually submit it to the IRS or most tax software platforms until that date. Some tax software will let you enter information and preview your return early, but transmission to the IRS will not happen until the season opens.

The delayed start gives the IRS time to update systems and gives employers and financial institutions time to send you the forms you need — W-2s, 1099s, and other income documents. Most employers must send W-2s by January 31, so waiting until late January or early February to file often means you have everything in hand.

Key Takeaways

  • The 2025 tax filing season opens January 27, 2025, and you cannot file before that date, even if you have all your documents.
  • April 15, 2025, is the important date to file your return or request an extension that gives you until October 15, 2025.
  • W-2s must be sent to you by January 31, 2025, so most people have what they need by early February.
  • Filing early can mean a faster refund, but only if your return is complete and accurate.
  • If you owe taxes, filing by April 15 avoids penalties and interest, even if you cannot pay the full amount when ready.

Why the IRS waits until late January to open filing

The IRS does not set the opening date arbitrarily. The agency needs time to reprogram its systems to handle the new tax year, update tax tables and standard deductions, and incorporate changes to tax law. For 2025, Congress and the IRS also need to finalize which tax provisions from recent years continue, expire, or change.

Employers and financial institutions also need time to prepare. Your employer must generate and send your W-2 by January 31. Your bank or brokerage must send 1099s for interest, dividends, and capital gains. If the IRS opened filing in early January, most people would not have these forms yet, and filing would be incomplete or inaccurate.

The delayed opening also spreads the filing load. If millions of people could file on January 1, the IRS systems and tax software companies would face a surge that could cause delays and errors. Staggering the start over several weeks helps the systems handle the volume.

What you can do before January 27

Gather your income documents as they arrive. Your employer should send your W-2 by January 31. If you are self-employed, compile your income and expense records. If you received interest, dividends, or capital gains, wait for the 1099 forms from your bank, brokerage, or mutual fund company — these are due by January 31 as well.

Collect receipts and records for deductions you plan to claim. If you itemize deductions, gather records of charitable donations, medical expenses, state and local taxes paid, and mortgage interest. If you take the standard deduction, you do not need receipts, but keeping them is still wise in case of an audit.

If you use tax software, many platforms let you create an account and start entering information before the filing season opens. You can preview your return and see what forms you still need. However, you cannot submit the return to the IRS until January 27.

Filing early versus waiting until April

Filing as soon as the season opens — late January or early February — means your refund arrives faster. The IRS typically issues refunds within 21 days of accepting your return, though it can take longer if you claim certain credits like the Earned Income Tax Credit. If you are counting on a refund to pay bills or cover expenses, filing early matters.

Waiting until March or April does not change your tax liability or the amount you owe or receive. It only delays your refund. However, some people wait because they are still gathering documents, working with a tax professional, or waiting for a corrected form from their employer or financial institution.

If you owe taxes, filing by April 15 is important. Filing late triggers penalties and interest, even if you cannot pay the full amount. If you cannot pay by April 15, you can request a payment plan or short-term extension through the IRS, but you must file the return itself by the important date.

What happens if you miss the April 15 important date

If you do not file by April 15, 2025, you can request an automatic extension that moves your important date to October 15, 2025. This extension gives you six more months to file, but it does not extend the time to pay taxes you owe. If you owe money, interest and penalties begin accruing on April 16.

To request an extension, file Form 4868 with the IRS before April 15. You can file this form electronically through tax software, by mail, or through a tax professional. Filing the extension form does not mean the IRS has approved it — you are notifying them that you need more time, and they grant it automatically if you file on time.

If you do not file by October 15 and do not have another extension in place, the IRS can assess a failure-to-file penalty. This penalty is typically 5% of the unpaid tax for each month the return is late, up to 25%. If you owe a large amount, this penalty adds up quickly.

How to file once the season opens

You have three main routes: file online using tax software, file by mail using paper forms, or work with a tax professional. Most people file online because it is faster, reduces errors, and produces a refund more quickly.

If you file online, you can use free IRS software if your income is below a certain threshold (this varies by year and filing status), or you can purchase software from a commercial provider. Both routes transmit your return electronically to the IRS. Paper filing is slower — the IRS must scan and process your forms, which can delay your refund by weeks.

If you work with a tax professional — a CPA, enrolled agent, or tax preparer — they can file on your behalf once the season opens. They handle the submission and can often file before you could do it yourself, especially if your situation is complex.

Documents you will need by filing time

Gather these documents before you sit down to file. Your W-2 from each employer (due by January 31). Any 1099 forms for self-employment income, interest, dividends, capital gains, or other income (due by January 31). If you received unemployment benefits, a 1099-G. If you made student loan interest payments, a 1098-E. If you paid mortgage interest, a 1098.

If you claim deductions, have records ready: receipts for charitable donations, medical expense bills, property tax statements, and mortgage interest statements. If you claim the Child Tax Credit or other credits, have your children's Social Security numbers and birth dates. If you made estimated tax payments during the year, have the payment confirmations.

If your situation changed during the year — marriage, divorce, a child born, a home purchase — have the relevant documents. The more organized you are before you start, the faster and more accurate your filing will be.

Frequently Asked Questions

Can I file my 2025 taxes before January 27?

No. The IRS will not accept 2025 returns before January 27, 2025. Some tax software will let you prepare and preview your return early, but you cannot submit it to the IRS until the filing season opens. Filing before the official date means your return will be rejected.

What if I do not have all my documents by January 27?

You can file without every document if you have the major ones — your W-2s and any 1099s for income. If a form arrives late, you can file an amended return (Form 1040-X) once you have it. However, if you are missing significant income information, waiting a few weeks to file is often safer than guessing.

Does filing early change how much tax I owe?

No. Your tax liability is the same whether you file on January 27 or April 14. Filing early only affects when you receive a refund or when you must pay taxes owed. If you owe money, filing late triggers penalties and interest, so filing on time matters for that reason.

What if April 15 falls on a weekend or holiday?

The IRS moves the important date to the next business day. In 2025, April 15 is a Tuesday, so the important date is April 15. If the important date falls on a Saturday or Sunday, or on a federal holiday observed in Washington, D.C., the IRS extends it to the next business day.

Can I file my 2024 taxes after January 27, 2025?

Yes. The 2025 filing season opening does not affect your ability to file 2024 returns. You can file a late 2024 return at any time, though penalties and interest will explore if you owed taxes for 2024. If you are due a refund for 2024, there is no penalty for filing late, but you should file within three years to claim it.
