When is the US tax filing deadline?
The federal income tax filing deadline is generally April 15 each year. For the 2025 tax year, the deadline is April 15, 2026. If you need more time, you can file for an extension, which gives you until October 15. Note that an extension to file is not an extension to pay.
What documents do I need to file?
You will need your Social Security number, W-2 forms from employers, 1099 forms for freelance or investment income, records of deductible expenses, and information about any tax credits you qualify for. If you are filing electronically, you will also need your prior year's AGI for verification.
How do I file my taxes?
You can file electronically using IRS Free File, commercial tax software, or a tax professional. Electronic filing is faster, more accurate, and you receive your refund sooner. You can also file by mail using paper forms, though this takes longer.
What happens if I miss the deadline?
If you miss the deadline without filing for an extension, you may face penalties and interest on any taxes owed. The failure-to-file penalty is generally 5% of the unpaid tax per month, up to 25%. It is better to file on time or request an extension.
