If you file this tax return after the due date, see the 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 on line 25 and write this amount on line 26. 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 left of page 2 and attach a written request. The written request must explain the circumstances that caused your tax return to be filed late. The Department may waive penalties or interest if the return was late because of circumstances beyond your control.
Add lines 25 and 26 and write the amount on line 27. This is amount you owe.
