When you work with us to complete your tax return filing we will apply the extension fee towards your tax return invoice. If you have questions or concerns about filing an extension please view our video below. As a reminder, filing an extension extends the time to complete your return by 6 months but does not extend the time to pay your taxes. If you typically owe, or expect to owe, make a payment towards your return by April 15 to reduce penalties and interest. Make payments here.
