How to File Your 38D Property Tax Return Online

Last updated:

38D Property Tax Returns are now open for Fiscal Year 2025.

Step
1

Review which form you need to submit

We mail notice letters starting in February. This letter will give you instructions on how to fill out the 38D Property Tax Return. You must return the Property Tax Return type that we request in the mailing. 

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.
