Matthew Gigantelli's Massachusetts Analysis

ASCSP Member M009-25 · Lead Cost Segregation Engineer

"Massachusetts is one of the highest-value cost segregation markets in the country. The 'millionaire's tax' surcharge pushes the top state rate to 9% for high-income investors, making every dollar of accelerated depreciation worth nearly 46 cents in combined federal+state savings. Boston and Cambridge have exceptional commercial property values, and the biotech/life sciences corridor along Route 128 and in Kendall Square produces lab and office properties with extremely high component density. Even without bonus depreciation at the state level, the numbers are compelling."

Bonus Depreciation Status

Massachusetts uses rolling IRC conformity but has decoupled from federal bonus depreciation under §168(k). Federal benefits are fully available. The state's "millionaire's tax" surcharge of 4% on income over $1M (bringing the top rate to 9%) makes cost segregation particularly valuable for high-income investors.

100% Bonus Depreciation Restored (July 2025): The One Big Beautiful Bill Act permanently restored 100% bonus depreciation for qualifying assets placed in service after 2022. This dramatically increases cost segregation ROI in Massachusetts.

How Cost Segregation Works in Massachusetts

Cost segregation is an IRS-approved tax strategy that reclassifies components of your Massachusetts property from the standard 39-year (commercial) or 27.5-year (residential) depreciation schedule to shorter 5, 7, and 15-year recovery periods. With 100% bonus depreciation restored under the One Big Beautiful Bill Act, these reclassified components can be fully depreciated in year one.

For Massachusetts property owners, this means turning a $5.0M commercial property into $65,000 - $185,000 of first-year tax savings instead of waiting decades for the same deduction.
