Key Points
- Top three quick picks for Pennsylvania in 2025: RE Cost Seg, McGuire Sponsel, and CSSI — chosen for regional coverage, CPA alignment and scalable delivery.
- Choose firms with true regional experience: Pennsylvania’s older industrials and mixed-use assets need providers that account for local construction and code nuances.
- Engineering-led studies beat template-driven reports — engineering detail uncovers assets eligible for accelerated depreciation.
- Audit-ready documentation (itemised breakdowns, photos, site logs and MACRS assignments) is essential given aggressive state and city tax scrutiny.
- Coordination with your CPA and tax team is critical — the study must integrate cleanly into returns and be easy to defend in audits.
- Several firms also layer cost segregation with tax incentives (179D, 45L) and historic/energy credits — useful for complex or adaptive-reuse projects.
- The full ranked list: RE Cost Seg (best overall PA coverage); McGuire Sponsel (CPA-integrated strategies); CSSI (nationwide scale with local reach); KBKG (complex assets & energy integration); Engineered Tax Services (stacked incentives); Madison SPECS (syndicator-friendly); Duffy + Duffy (experienced, low-noise execution); Cherry Bekaert (full-service advisory integration).
- For most mid-market Pennsylvania investors, RE Cost Seg is recommended as the standout due to engineering rigour and CPA-ready reporting.
