Deadline to file your federal income tax return (Form 1040) and pay any taxes owed.
Tax Day is the most important annual tax deadline in the United States. Individual taxpayers must file their federal income tax return covering the prior calendar year (e.g., April 15, 2025 is for 2024 taxes) and pay any taxes owed.
The deadline applies to most taxpayers who have filing obligations. Even if you owe no taxes, filing may be required if you received income, and you may be eligible for refundable tax credits (Earned Income Tax Credit, Child Tax Credit, etc.) that can result in a refund.
The IRS allows automatic 6-month extensions (until October 15) if you file before the April deadline. However, an extension to file does not extend the deadline to pay taxes owed — estimate your tax and pay by April 15 to avoid penalties and interest.
State income tax returns are typically due on the same date as federal returns (April 15), though some states have different deadlines. Check your state's revenue agency for specific rules.
Extensions are free and automatic if requested on your return (or using Form 4868). Filing late without requesting an extension results in failure-to-file penalties.
Missing Tax Day without an extension or payment results in:
- Failure-to-file penalty: 5% of unpaid taxes per month (max 25%)
- Failure-to-pay penalty: 0.5% of unpaid taxes per month (max 25%)
- Interest: Currently ~8% annually, compounded daily
- Potential audit and legal action if intentional evasion is suspected
- Loss of refunds or credits (3-year statute of limitations for claiming refunds)
Add this deadline to your phone, calendar, or reminder app 2–3 weeks in advance to avoid last-minute stress.
