Massachusetts Interest and Penalties
Massachusetts imposes interest and penalties on unpaid or underpaid state income taxes. These charges apply when taxpayers fail to pay their full tax liability by the due date or when they file their returns late. The Massachusetts Department of Revenue (DOR) enforces these rules to ensure timely compliance with state tax obligations.
Interest Charges
- Interest is charged on any unpaid tax balance from the due date of the return until the date of payment.
- The interest rate is determined by the DOR and is typically based on the federal short-term rate plus 3 percentage points.
- Interest applies to both individual and business taxpayers who owe Massachusetts income tax.
Penalty for Late Filing
- A late filing penalty of 5% of the unpaid tax is assessed for each month or part of a month the return is late, up to a maximum of 25%.
- This penalty applies if the return is filed more than 60 days after the due date, regardless of whether a balance is owed.
Penalty for Late Payment
- A late payment penalty of 0.5% of the unpaid tax is charged for each month or part of a month the payment is overdue, up to a maximum of 25%.
- These penalties are in addition to any interest accrued on the unpaid balance.
Payment and Filing Instructions
- Taxpayers must mail their original or amended Form 1 (Massachusetts Individual Income Tax Return) to: Massachusetts Department of Revenue, PO Box 7003, Boston, MA 02204-7003.
- If using tax software, ensure the correct PO box is selected as specified on the inside front cover of the tax booklet.
- For electronic filing, use Form M-8453 (Individual Income Tax Declaration for Electronic Filing) to submit returns electronically.
