Estimated tax payment due April 15 IR-2021-67, March 29, 2021

Notice 2021-21, issued today does not alter the April 15, 2021, deadline for estimated tax payments; these payments are still due on April 15. Taxes must be paid as taxpayers earn or receive income during the year, either through withholding or estimated tax payments. In general, estimated tax payments are made quarterly to the IRS by people whose income isn't subject to income tax withholding, including self-employment income, interest, dividends, alimony or rental income. Most taxpayers automatically have their taxes withheld from their paychecks and submitted to the IRS by their employer.
