Tax Deadlines In 2019 – For Individual Filers

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 individual filers 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 2019. Here are some of the important deadlines.

First Quarter

January, February, & March Tax Deadlines


January 15: Estimated quarterly tax payments for Q4 of 2018 are due.

January 31: Form W-2 and 1099-MISC for non-employee compensation (box 7) must be filed with the IRS and furnished to individuals by this deadline.


February 15: Individuals who claimed exemption from income tax withholding in 2018 on Form W-4, Employee’s Withholding Allowance Certificate, must file a new Form W-4 with their employer by this date to continue their exemption for another year.


March 1: Ordinarily, farmers who did not pay all estimated tax payments by January 15 must file by March 31 each year. However, for 2019 only, the IRS is allowing farmers to file and pay all taxes due by April 15.

March 15: S corporation and partnership tax returns are due. This is the deadline to file an S corporation and partnership tax extension, as well.

Second Quarter

April, May, & June Tax Deadlines


April 15: TAX DAY! Your individual 2018 income tax return is due. If you want an automatic 6-month extension of time to file the return, file Form 4868 and pay what you estimate you owe in tax to avoid penalties and interest.
