Review which form you need to submit

We mail notice letters in February. This letter will give you instructions on how to fill out the 38D Property Tax Return. Please note: You must return the Property Tax Return type that we request in the mailing. You can submit six different forms online:

  • Form A2, if you own or lease an apartment or lodging property
  • Form H, if you own or lease a hotel, motel or a bed and breakfast
  • Form NC, if you own or lease a new construction property
  • Form O, if you own or lease an office building
  • Form PK, if you own or lease a parking facility, and
  • Form SH, if you own or lease subsidized housing
Please note:

You must file your return within 60 days of the mailing date on the notice. If you fail to comply within 60 days of the request, it may be grounds for dismissal of a filing at the appellate tax board. You may also face a fine of $50 for residential properties, or $250 for commercial or industrial properties. Massachusetts General Laws, Chapter 59, § 38D has more information.


Download and complete an Excel form

To make sure we are efficient and accurate, we require you to download an Excel workbook, complete it, then submit your return online. You'll need to attach your completed Excel workbook, along with any other documents, to your online submission.

If you can't file online, please contact us to receive a paper copy of the return.

The 38D Property Tax Return is an Excel workbook. When you open the workbook, you must click “Enable Editing” at the top of your screen. We have more detailed instructions in the Excel workbook about how to fill it out.
