Last updated: November 12, 2026

The best cost segregation firms in New Jersey for 2027 are Madison SPECS, Cost Recovery Solutions and Withum, followed by Cost Seg EZ, Engineered Tax Services and Capstan Tax Strategies. Madison SPECS leads for in-house engineers with deep Northeast experience, Cost Recovery Solutions for a New Jersey firm based in Metuchen, and Withum for a Princeton accounting firm founded in 1974.

New Jersey investors own Jersey City and Hoboken apartments, North Jersey industrial near the ports, Shore vacation homes and suburban office and retail. The One Big Beautiful Bill Act made 100% bonus depreciation permanent for qualifying property acquired after January 19, 2025, so reclassified components can often be deducted in the first year on the federal return.

New Jersey does not follow federal bonus depreciation, and it caps Section 179 expensing at $25,000. That means the state deduction is spread over the normal recovery periods, while the federal benefit arrives up front. Your CPA will need to keep separate New Jersey depreciation schedules.
