Certain taxpayers must make estimated tax payments throughout the year. Taxpayers must generally pay at least 90 percent of their taxes throughout the year through withholding, estimated tax payments or a combination of the two. If they don’t, they may owe an estimated tax penalty.
Estimated tax is the method used to pay tax on income that is not subject to withholding. This income includes earnings from self-employment, interest, dividends, rents, and alimony. Taxpayers who do not choose to have taxes withheld from other taxable income should also make estimated tax payments.
The due dates of the payments are based on the following table.
||January 1 – March 31
||April 1 – May 31
||June 1 – August 31
||September 1 – December 31
