Cost Segregation in Mason, Ohio 

Mason has developed into a high-income commercial market characterized by corporate office campuses, retail centers, and planned commercial developments. These properties frequently involve tenant build-outs, mechanical systems, structured parking, and exterior site improvements that must be properly classified for depreciation purposes.


When commercial real estate is constructed, renovated, expanded, or acquired, the associated costs require structured evaluation. A Cost Segregation analysis provides an engineering-based review to determine whether certain building components may qualify for shorter recovery periods under applicable tax guidance.


Since 2004, RCG has completed more than 25,000 R&D tax credit studies and identified over $750 million in tax savings. RCG applies the same documentation-focused and compliance-driven methodology to Cost Segregation engagements performed in Mason.

Mason’s Corporate and Retail Property Profile 

Mason’s commercial landscape commonly includes:

Corporate headquarters and regional offices

Professional office parks

Retail shopping centers

Lifestyle and mixed commercial developments

Service-oriented commercial facilities

Corporate office facilities often contain extensive interior build-outs, HVAC systems, electrical infrastructure, and shared mechanical systems. Retail centers may include storefront construction, parking lot improvements, signage infrastructure, and common-area mechanical installations.


These features require technical analysis to determine appropriate depreciation classification.



Each property must be evaluated individually based on documentation and physical characteristics.

What a Cost Segregation Study Evaluates 

A Cost Segregation Study examines construction-related costs to determine whether certain components may qualify for 5-, 7-, or 15-year recovery periods, instead of standard 27.5- or 39-year treatment.


RCG’s structured methodology generally includes:

Project Documentation Review 

  • Contractor payment applications
  • Construction invoices
  • Change orders
  • Depreciation schedules
  • Final project cost summaries

Onsite Engineering Inspection

A physical inspection is conducted to evaluate building systems, tenant configurations, and operational characteristics. Photographs of qualifying components are incorporated into the final report.

Engineering-Based Cost Reconciliation

  • Blueprint review when available
  • Quantity take-offs and cost estimation where necessary
  • Reconciliation of total project costs by tax life
  • Allocation of applicable soft costs
  • Preparation of a report aligned with IRS Cost Segregation Audit Technique Guide standards

The objective is proper classification supported by engineering documentation and reconciliation.

Ohio Tax Considerations

Ohio income tax calculations begin with federal adjusted gross income but may include state-level modifications. Certain federal bonus depreciation deductions under IRC §168(k) may require adjustment under Ohio law.


Ohio’s Commercial Activity Tax (CAT) is measured by taxable gross receipts rather than net income. Accelerated depreciation generally impacts income tax liability rather than CAT liability.



Implementation decisions should be coordinated with a qualified CPA or tax advisor.

RCG’s Technical Approach

Experience in Technical Tax Services - Since 2004, RCG has completed more than 25,000 R&D tax credit studies and identified over $750 million in tax savings.

Common Misconceptions

“Office properties offer limited opportunity.” 

Corporate and professional buildings often contain tenant improvements and infrastructure requiring technical evaluation.


“Retail centers are fully long-life property.” 

Retail facilities frequently include site improvements and interior systems that warrant structured review.
