When Are Taxes Due?

Tax return items with reminder note

It's very important to file your income tax returns before the deadline. It not, you could find yourself facing stiff penalties. Fortunately, there is consistency regarding the timeframe that U.S. taxes need to be submitted each year.

Annual Federal Income Taxes

Annual income taxes are generally due at the same time each year.

Individual Taxes

Annual individual federal tax returns are generally due on April 15 each year. In years that this date falls on a weekend or federal holiday, the due date is moved to the first business day after the 15th of April.

Business Taxes

The due date for annual business taxes varies based on business type and fiscal year (FY). Tax returns for S-corporations and partnerships that use a calendar year FY are due on March 15, while C-corporations that use the same type of FY have an April 15 due date. As with the deadline for individual returns, if the due date falls on a weekend or federal holiday, the filing deadline will be moved to the following business day.

For details on other forms of businesses or those with an alternate FY structure, see the due date summary provided by the American Institute of Certified Public Accountants (AICPA).

Quarterly Estimated Taxes

Taxpayers who file estimated income taxes on a quarterly basis also need to keep up with these deadlines. IRS deadlines by quarter are as follows:

  • April 15
  • June 15
  • September 15
  • January 15

These timeframes apply to individual taxpayers as well as businesses. As with annual taxes, the deadline is adjusted to the next business day when the actual due date falls on a weekend or federal holiday.

Additional Filing Deadlines

While annual and estimated quarterly taxes are the most common filing deadlines (because they apply to the majority of the population), other tax filing requirements and associated deadlines apply to some individuals and businesses. See this detailed tax calendar if you are looking for due dates for other types of taxes.

State Filing Deadlines

For states that require income taxes to be filed, the deadline is usually the same as the applicable federal deadline. To be certain, you should verify with your state tax agency or your tax professional.
