Tax Deadlines In 2020

While Tax Day (April 15th this year) is the only date some people may have on their calendar when it comes to tax deadlines, there are actually many important tax dates throughout the year. These due dates impact both businesses and individuals. The dates you’ll need depend on your unique situation.

What is a Tax Calendar?

A tax calendar is a 12-month calendar divided into quarters. This calendar gives specific due dates for:

  • Filing tax forms
  • Paying taxes
  • Other actions taxpayers may have to take as required by federal tax law

This tax calendar is suitable for individual tax filers, small businesses, and employers. It contains information about how to use the calendar and general tax deadlines throughout 2020. Here are some of the important deadlines.
