Overview

If you owe interest or penalties for underpayment, late payment, or late filing of your Massachusetts state taxes, you may need to complete the Interest and Penalty Worksheet on your return. This form helps calculate the amount due and ensures compliance with Massachusetts Department of Revenue (DOR) regulations.

Generally, you should complete the Interest and Penalty Worksheet if:

• You are filing your return after the due date and have a balance.
• You are subject to failure-to-pay, failure-to-file, or underpayment penalties.
• You are proactively calculating interest to avoid future assessments.
