In 2027, April 15 falls on a Thursday, so the deadline is April 15 with no shift. When Tax Day falls on a weekend or a Washington DC holiday (such as Emancipation Day on April 16), the deadline shifts to the next business day.
Why April 15?
The April 15 deadline was set by the Revenue Act of 1954, signed by President Eisenhower. Before that, Tax Day was March 15 (set in 1918) and originally March 1 (when the modern income tax was established by the 16th Amendment in 1913).
Congress moved the deadline from March 15 to April 15 in 1955 to give taxpayers more time to organize records and to spread the IRS workload across additional weeks.
What Tax Day Means
Tax Day is the deadline by which most US taxpayers must file their federal income tax return for the previous calendar year. The return covers income earned January 1 through December 31 of the prior year.
For Tax Day 2027 (April 15, 2027), the return covers tax year 2026.
If you cannot file by April 15:
- File Form 4868 to request an automatic 6-month extension. This pushes your filing deadline to October 15, 2027.
- Pay any tax owed by April 15 even if you file an extension. Extensions extend the filing deadline only, not the payment deadline. Unpaid taxes accrue interest and penalties starting April 16.
Estimated Tax Deadlines
Self-employed workers and others without sufficient tax withholding must pay quarterly estimated taxes. The 2027 quarterly deadlines:
- Q1 2027 estimated taxes (covering Jan-Mar 2027): April 15, 2027
- Q2 2027 estimated taxes: June 15, 2027
- Q3 2027 estimated taxes: September 15, 2027
- Q4 2027 estimated taxes: January 15, 2028
Failure to pay estimated taxes when required can trigger underpayment penalties even if the full balance is paid by Tax Day.
State Income Tax Deadlines
Most states with income taxes use April 15 as their state deadline as well. State deadlines may vary in years when April 15 shifts due to weekends or holidays.
Nine US states have no state income tax for wage earners:
- Alaska
- Florida
- Nevada
- New Hampshire (no tax on wages, taxes interest and dividends through 2024 only)
- South Dakota
- Tennessee
- Texas
- Washington
- Wyoming
If you live in one of these states, you only file a federal return (assuming no other income sources triggering state filing).
