If You Miss the Tax Filing Deadline or Need an Extension: Here’s What To Do (2025 Guide)

Missed the tax deadline? Here's what to do next.

Table of Contents

Let’s be real: life happens. Whether it’s a mountain of responsibilities, personal setbacks, or just forgetting the date, missing the tax filing deadline doesn’t make you a criminal—it makes you human. But if you’ve missed that April 15, 2025, cut-off (or you know you’re not going to make it), there are still smart, proactive steps you can take to fix it.

First Things First: Don’t Panic—Act Fast

Missing the IRS tax filing deadline isn’t the end of the world, but ignoring it could lead to penalties, interest, and a headache that lasts way longer than tax season. Here’s what you need to know and do, in plain, real-world language.

If You Haven’t Missed the Deadline Yet (April 15, 2025)

File an Extension NOW

If you know you won’t be ready, you can request an automatic six-month extension using Form 4868, which gives you until October 15, 2025, to file your return. Here’s how:

Ways to Request an Extension:

  • IRS Direct File (Free): If eligible, you can request an extension directly on the IRS site. It’s free and available even after April 15 (but don’t delay on payments).
  • IRS Free File: If your adjusted gross income (AGI) was $84,000 or less in 2024, you can file Form 4868 for free with guided software until October 15.
  • IRS Free Fillable Forms: For those over the income limit, this no-cost option still lets you e-file Form 4868.
  • Tax Software: Tools like TurboTax, H&R Block, TaxAct all have built-in options to file an extension quickly.
  • Tax Professional: Not a DIYer? A tax pro can handle it all—either electronically or via mail.
  • Mail: Download and fill out Form 4868, then mail it to the correct IRS address. But FYI—e-filing is faster and gives you confirmation.

What an Extension Does (and Doesn’t) Do

Let’s clear this up—because it trips up a lot of people:

  • YES: You get six more months to file your paperwork.
  • NO: It does not give you more time to pay. You still owe taxes by April 15, 2025.

Translation:

You can delay the paperwork, but the IRS still wants their money on time. If you expect to owe, estimate your tax liability and pay by April 15 to avoid extra fees.

Already Missed the Deadline Without an Extension?

Here’s what you need to do—immediately:

  1. File Your Return ASAP – Whether you’re doing it electronically or by mail, don’t delay any further.
  2. Expect Penalties (But Minimize Them):
    • Late Filing Penalty: 5% of unpaid taxes per month (up to 25% max).
    • Late Payment Penalty: 0.5% per month (also up to 25%).
    • Interest: Charged on any unpaid tax from the original due date.

Even if you can’t pay in full, file something to avoid the higher filing penalty. You can set up a payment plan with the IRS online if needed.

Key Terms to Know:

  • Form 4868: This is the form you file for an extension.
  • Adjusted Gross Income (AGI): Your gross income minus specific deductions. The IRS uses this number to determine eligibility for free services.
  • Extension to File vs. Extension to Pay: You get more time to submit your tax return, not more time to pay what you owe.

Pro Tip:

If you’re struggling, talk to a tax professional like us. It might cost you upfront, but it could save you from bigger financial issues and unnecessary penalties down the line.

Final Thoughts

  • File for an extension if you can’t meet the April 15 deadline.
  • Pay what you owe by April 15 to avoid penalties.
  • If you already missed the deadline and didn’t request an extension—file ASAP.
  • Don’t ignore it—taking action now makes things easier later.
