Taxpayers should know that an extension to file is not an extension to pay taxesTaxpayers who aren’t able to file by the April 18, 2023, deadline can request an extension before that deadline, but they should know that an extension to file is not an extension to pay taxes. If they owe taxes, they should pay them before the due date to avoid potential penalties and interest on the amount owed.
Taxpayers who request a six-month extension to file their taxes have until October 16, 2023, to file their 2022 federal income tax return.
