Annual Business Income and Expense Filing


The Cambridge Board of Assessors has adopted an electronic filing process for Income and Expense data. This request to fill out an online form constitutes the Department’s request for a written return under oath pursuant to Massachusetts General Laws Chapter 59, Section 38D. The Department requests detailed information regarding recent leases, parking income, other forms of income, rentable area’s use of space and total leased area, expenses, extraordinary expenditures, sales transactions, issues that contend value, and the rent roll as of January 1st. 

Please follow this link Income and Expense Form, Start New Application to find your parcels, using our service provider Just Appraised. Follow the instructions on the entry forms.  The rent roll can either be entered in the form directly or uploaded from a comma delimited file (CSV) with the required columns. The Assessing Department recommends using the CSV for apartments with eight or more units or tenants. The following templates should help format your rent roll data for easier completion; Apartment Template and Commercial Template. For instructions on converting a file from Excel to CSV, please see this link.

Complete all forms then sign and submit along with an uploaded rent roll image as of January 1st. Upon submission, an electronic receipt will be sent to the email address provided.

The City of Cambridge Assessing Department is requesting specific income and expense data during the prior calendar year for the purposes of analysis and valuation as of this January 1st.

Please be advised that all information filed is subject to the confidentiality requirements of Chapter 59 of the Massachusetts General Laws.

If any owner or lessee of real property in a return made under this section makes any statement which he knows to be false in a material particular, such false statement shall bar him from any statutory appeal under this chapter.
