Cambridge, Massachusetts, could be headed for another steep increase in commercial property taxes, extending a recent trend that is straining business owners while raising broader concerns about what could come next for homeowners.
City Manager Yi-An Huang's plan calls for a 21% increase in the commercial tax rate and a 4% increase in the residential rate, after commercial property values declined and as the city tries to prevent even larger increases for homeowners.
Here's what to know
The City Council was set to vote Sept. 28 on whether Cambridge will charge $16.99 per $1,000 of commercial property value and $6.95 per $1,000 of residential value, according to Cambridge Day.
That would follow fiscal 2026's 22% increase in the commercial rate, making it the second large jump in two years and pushing the total increase since fiscal 2025 to 47%.
The proposal reflects broader shifts in Cambridge's property values. Cambridge Day reported that the city's total assessed value has fallen by about $3 billion for a second straight year, even as residential values continued to rise. Commercial property also now makes up a smaller share of the city's overall value, though it would still account for 62% of total tax revenue under the plan.
City Councilor and Finance Committee Co-Chair Patty Nolan said a higher rate will not automatically produce an equally large increase for every business taxpayer.

"For many small businesses, very few will see an actual 21% increase," she said.
More background
Property taxes can affect rents, storefront stability, and household budgets.
For homeowners, the impact varies by property type. Condominium owners are expected to see relatively small changes because condo values have grown slowly, while owners of single-, two-, and three-family homes could see their taxes rise by roughly $800 or more. Owner-occupants can also qualify for a 30% discount.
Commercial owners will not be affected uniformly, either. Office-building owners may see little change because office values have dropped so much. Owners of retail, restaurant, and hotel properties could face steeper increases.
Cambridge is still below its legal taxing limit, but a continued run of similarly sharp commercial increases could bring the city to that ceiling within two years. At that point, officials would face a more difficult choice between higher residential taxes and budget cuts.
What's being done?
The next important step is the council's vote. The council usually approves the annual tax rates, though Cambridge Day said the charter-right process has occasionally delayed that action.
Cambridge also remains under the limit allowed by Massachusetts' Proposition 2½ rules. The city is expected to be at about 82% of its maximum levy, meaning it has not yet hit the legal cap.
Nolan said city officials have been in touch with business owners ahead of the Sept. 28 vote so they would be aware of the increases. She also said an override remained possible, though she did not expect one.
What someone ultimately owes depends on assessment changes, owner-occupancy discounts, and exemptions connected to age, family structure, disability status, or military-veteran status, as Cambridge Day noted.
As Nolan put it, the city is trying to avoid placing too much of the burden on households.
"While it may seem reasonable to say, 'Well, let's just raise the taxes for residential,'" she said of taxpayers. "If we want to continue to be conscious of and sensitive to the middle class in Cambridge, I think we have to tread very carefully. You may not have an extra $1,000 just hanging around."
