Tax Day is on Thursday, April 15, 2027, the usual deadline for filing federal income tax returns. It’s the date most Americans must file their return, or request an extension, and pay any tax they owe. When April 15 falls on a weekend or holiday, the deadline moves to the next business day.
When Is Tax Day?
For most people, it’s April 15. The IRS says that if the date lands on a weekend or legal holiday, the deadline shifts to the next business day. A return mailed on time counts if it’s properly addressed, postmarked and sent by the due date.
Some taxpayers get more time. People in federally declared disaster areas may receive postponements, and special rules apply to service members in combat zones.
Why Is Tax Day April 15?
The 16th Amendment, adopted on February 3, 1913, gave Congress the power to tax incomes. The first deadline was March 1. The Revenue Act of 1918 moved it to March 15.
The deadline shifted to April 15 starting in 1955, the Tax Foundation notes. An IRS spokesman later said the move helped spread out the agency’s peak workload.
What Is the Deadline For?
It’s the annual deadline to settle up with the federal government for the previous year’s income. Most workers have tax withheld from each paycheck, so the return reconciles what was withheld with what they actually owe. Many people get a refund; others owe more.
Tax Day isn’t a federal holiday, so banks, post offices and government offices stay open.
How to Prepare for Tax Day
- Gather your forms early: W-2s, 1099s and mortgage or tuition statements usually arrive by early February.
- File electronically: e-filing with direct deposit is typically the fastest way to get a refund.
- Request an extension if needed: file Form 4868 by the deadline for six more months to file.
- Pay what you can on time: even a partial payment reduces penalties and interest.
- Keep copies: save your return and supporting documents; the IRS says three years is the usual minimum, with longer periods in some cases.
- Set up a payment plan: the IRS offers online payment agreements if you can’t pay in full.
- Check your state: most states with income taxes have their own deadlines, often the same day.
What Happens if You File or Pay Late?
The IRS charges a failure-to-file penalty of 5% of unpaid tax for each month a return is late, up to 25%. For returns more than 60 days late, the minimum penalty is $525 or 100% of the tax owed, whichever is less, for 2026 due dates.
The failure-to-pay penalty is 0.5% of unpaid tax per month, also capped at 25%. It drops to 0.25% a month if you filed on time and set up an approved payment plan.
Frequently Asked Questions
Does an extension give me more time to pay?
No. Form 4868 gives you six more months to file, not to pay. Pay any tax you expect to owe by the original deadline to avoid penalties.
What if I’m owed a refund and file late?
The failure-to-file penalty is based on unpaid tax. If you’re due a refund, you generally won’t owe that penalty, but you should still file to claim your money.
Why is Tax Day sometimes April 17 or 18?
Weekends and a D.C. holiday. In 2023, April 15 fell on a Saturday and Emancipation Day was observed Monday in Washington, D.C., so the deadline moved to April 18.
Can I file my taxes for free?
Possibly. IRS Free File offers guided software at no cost for taxpayers with adjusted gross income of $89,000 or less. Free fillable forms are available at any income level.
Is Tax Day the same in every state?
No. States set their own deadlines, and some states have no income tax. Check your state revenue department’s website.
