What are additions to fees and how are they computed?
Addition to fees is a penalty charged for failure to pay or failure to file the required return(s) by the due date. When your return has been filed, but not paid by the required due date, you should calculate your penalty by multiplying the tax amount due by 5 percent. This penalty does not increase. When no return has been filed, you should calculate your penalty by multiplying the tax amount due by 5 percent for each month you are late. This penalty increases each month you fail to file the return. The maximum amount of penalty is 25 percent. Note: Do not calculate interest on the amount of additions to tax due. Please visit our interest and additions calculator.
