If you filed for a tax extension earlier this year, your time is almost up. The extended deadline to file your federal income tax return is October 15, and missing it can trigger penalties, interest charges, and lost opportunities for refunds or deductions.
Whether you’re a small business owner, self-employed professional, or individual taxpayer who needed more time in April, this guide walks you through everything you need to know before October 15 rolls around.
Each year, millions of taxpayers file IRS Form 4868 to request an automatic six-month extension on their tax return. But while this extension gives you extra time to file, it does not give you extra time to pay.
The original tax due date — April 15 — remains the deadline for payment. So if you owed taxes and didn’t pay by then, interest and penalties have already been accruing. However, filing your return by the October 15 deadline can help reduce additional late filing penalties and help you claim refunds or credits you’re entitled to.
Missing the October 15 extension deadline comes with serious consequences:
The IRS can charge you 5% of the unpaid tax for each month your return is late, up to a maximum of 25%. This is on top of any failure-to-pay penalties you already face.
Unpaid taxes accrue interest at the federal short-term rate plus 3%, compounded daily. Even if your tax balance is small, these costs can add up quickly over time.
If you’re due a refund and don’t file within three years, the IRS can keep your money. Don’t leave your own cash on the table.
Missing the deadline can cause complications with future tax filings, impact business records, or delay your ability to apply for loans or mortgages that require proof of tax compliance.

Even if you can’t pay the full amount you owe, you should still file your return by October 15 to avoid the steeper failure-to-file penalties.
Here are your options:
Gives you up to 180 days to pay the full amount. No setup fee, but interest continues to accrue.
