Would you support higher property taxes to keep local services in your area?

Cambridge administrators have proposed capping fiscal year 2028 tax levy and budget growth at 5.5%, even as residential property tax rates could rise 10% to 15%. Owners of one-to-three family homes face the largest increases.

Why it matters

The city faces a projected $6.7 million deficit if existing services are maintained, while commercial property values keep declining and high interest rates have slowed development. Property taxes are covering a larger share of the budget because service charges, licenses, and permits have grown more slowly than spending.

The city seeks $7 million in cuts to current spending against a $57 million anticipated operating budget increase. Residential tax rates rose an average of 7% in fiscal year 2027, and reserves have fallen 20% over two years.

The players

Harvard University

A tax-exempt research university whose voluntary payments in lieu of taxes to Cambridge are a key component of the city's revenue projections.

City of Cambridge

The Massachusetts municipality whose administrators set the levy cap and budget proposal affecting local property owners and businesses.

The details

Property taxes cover a larger share of Cambridge's budget because revenue from service charges, licenses, and permits has grown more slowly than spending. Commercial property values continue to decline while employee cost-of-living adjustments and capital project debt payments rise, shifting the burden onto residential owners. Buildings with one to three family units face the greatest increases because those properties have appreciated the most. Harvard's voluntary payments in lieu of taxes, made under agreements allowing tax-exempt universities to contribute to surrounding communities, are a key assumption in the city's projections.

March 2025: Harvard signed a $6 million in-lieu-of-tax agreement with Cambridge.
Fiscal year 2027: Residential tax rates increased an average of 7%.
2027 calendar year: An extra 53rd employee paycheck requires drawing on free cash reserves.
Fiscal year 2028: Proposed 5.5% cap on tax levy and budget growth.

Market Landscape

Cambridge's budget depends on voluntary in-lieu-of-tax agreements with Harvard, which the city's projections assume will renew at $6 million. Declining commercial values and slowed development leave residential owners carrying a growing share of the levy.

Owners of one-to-three family buildings and commercial landlords should model residential rate increases of 10% to 15% in their planning. Businesses reliant on city services or permits should review how a tighter levy cap could affect fees and service levels.

The takeaway

Operators should treat the 5.5% levy cap as a signal that residential and commercial property costs will keep rising. Owners should consult a qualified accountant about how a projected 10% to 15% tax increase affects their Cambridge property expenses.
