The Internal Revenue Service today reminded self-employed individuals, retirees, investors, businesses, corporations and others who pay their taxes quarterly that the payment for the first quarter of 2021 is due Thursday, April 15, 2021.

The extension to May 17, 2021 for individuals to file their 2020 federal income taxes does not apply to estimated tax payments. The 2021 Form 1040-ES, Estimated Tax for Individuals, can help taxpayers estimate their first quarterly tax payment.
