Individual Tax Return Deadline — April 15

Who must file or pay

All U.S. taxpayers required to file a federal income tax return for tax year 2025 (income thresholds vary by filing status — generally $14,600 single, $29,200 MFJ for 2025).

What you need to know

April 15, 2026 is the deadline to file your 2025 federal individual income tax return (Form 1040) or request a 6-month extension. If you owe taxes, payment is still due April 15 even if you file an extension.

For the 2026 filing season, keep in mind that the Tax Cuts and Jobs Act provisions expired at the end of 2025. This means 2025 tax returns are filed under transitional rules: the standard deduction, personal exemptions, and many deduction limits may differ from what you've seen in recent years. Confirm current thresholds with a licensed tax professional.

With TaxosAgent, a licensed professional reviews your return before it is filed. Upload your documents, let Genie analyze your situation, and receive a strategy call to confirm every deduction before you sign.

Failure-to-file penalty: 5% of unpaid tax per month, up to 25%. Failure-to-pay penalty: 0.5% of unpaid tax per month. Interest accrues on unpaid tax from the original due date. If you cannot pay in full, file on time to avoid the larger failure-to-file penalty, and apply for an installment agreement.
