Subtotal (Minus Credits)

If you file this tax return after the due date, see penalty rates above the signature line on page 1 of the tax return to find the penalty rate. Multiply the penalty rate by the subtotal (minus credits). Write that amount on this line. There is no penalty if no tax is due.

If you are filing late and are requesting a waiver of penalty, please check the box at the bottom of page 1 and attach a written request. The written request must explain the circumstances that caused your tax return to be filed late. We may waive penalties or interest if the return was late because of circumstances beyond your control.
