If you do not pay the full amount you owe by the tax deadline, even if you file an extension, you will be assessed a penalty of 0.5% of your balance due per month. The amount of your failure-to-pay penalty will not exceed 25% of your back taxes.

If you do not pay your full balance due, you will also owe interest on the unpaid amount.The interest rate is set quarterly by the federal government.

The current 2016 interest rate for underpayment of taxes is 4%.
