Understanding Property Taxes In Boston (2025)

Boston's tax rates and residential exemptions in 2025 reflect shifts in property valuations, state law, and local fiscal policy.

 

Current Rates And Exemptions

The City of Boston has set the FY2025 residential tax rate at $11.58 per $1,000 of assessed value, a noticeable increase from the previous year's rate of $10.90. Commercial property is taxed significantly higher at $25.96 per $1,000, underscoring the city's longstanding split-rate system. Importantly, Boston continues to apply the maximum residential exemption, reducing the taxable value of owner-occupied homes by $3,984.21.

For example, a property assessed at $750,000 would have its taxable amount reduced to approximately $746,016, resulting in a bill of about $8,643 before any further exemptions.

 

How Boston Calculates Assessed Value

Assessments are based on market value as of January 1st of the previous year, adjusted annually. Neighborhoods with rapid development or renovation tend to experience steeper increases. Unlike sale price, assessed value often lags, creating temporary disparities buyers must be ready for. Home improvements—especially those visible in public records—can trigger reassessments in subsequent years.

Boston also allows taxpayers to view assessments and property tax bills via the city's online portal, making it easier to track value trends year to year.

 

Factors Driving The 2025 Property Tax Increase

Three key elements have caused property tax burdens to increase for many homeowners this year:

 

1. Decline In Commercial Valuations

 

3. Legislative Gridlock

A proposal by Mayor Michelle Wu to shift more tax responsibility onto commercial property was stalled in the state legislature. Without that reclassification, homeowners are bearing a disproportionate share of the municipal tax base, particularly in neighborhoods with fewer corporate properties.

 

Strategic Tax Planning For Boston Buyers

Savvy homebuyers in 2025 should consider more than just purchase price when estimating long-term affordability.

 

Leveraging The Residential Exemption

One of Boston's most valuable tax relief tools is its residential exemption. To qualify, the property must be your principal residence on January 1 of the tax year. This exemption reduces the taxable value significantly—by nearly $4,000 in 2025. Buyers should work with their agent and closing attorney to ensure all paperwork is filed promptly so benefits apply in the next billing cycle.

 

Appealing An Assessment

If your new home is assessed above market value, you can appeal. The City of Boston allows homeowners to request abatements, usually from January to February each year. Filing requires submitting comparable sales, appraisal documents, or proof of depreciation. This can result in substantial savings, especially in neighborhoods with inconsistent assessments.

 

Evaluating Neighborhood Trends

Property taxes can vary dramatically by area depending on how aggressively local values have climbed. Some neighborhoods, like West Roxbury or Hyde Park, may offer stable tax expectations, while others—like Seaport or Fort Hill—can experience valuation surges within short periods. Real estate consultants can provide year-over-year data to forecast how taxes may rise after purchase.
