Our Cost Segregation Services

Comprehensive engineering-based cost segregation solutions designed to maximize depreciation deductions and accelerate tax savings for Oregon property owners.

Cost Segregation Study

A full engineering-based analysis that reclassifies property assets into 5-, 7-, or 15-year depreciation categories, unlocking significant accelerated deductions. Includes audit defense, depreciation schedules, and CPA-ready reporting — completed in 2–4 weeks.

Lookback Study

Claim missed depreciation on properties placed in service up to 15 years ago — without amending prior returns. Using IRS Form 3115, all catch-up deductions are applied in a single tax year, recovering years of overlooked savings.

Virtual Property Tours

A convenient 30–45 minute video-call inspection that replaces costly on-site visits. Our engineers conduct real-time component identification and digital documentation, delivering faster turnaround times of 2–3 weeks with no disruption to your schedule.

IRS Audit Defense

Every study includes Seneca AuditDefense at no extra cost — covering you for the entire duration of property ownership. If an audit occurs and the study has a material issue, we can refund the cost of your study.

CPA Coordination & Support

Post-study support ensuring seamless implementation of your cost segregation findings. Our team coordinates directly with your CPA or tax advisor to integrate depreciation schedules into current returns or via Form 3115 for lookback studies.

Rush Service

Need your study completed before a critical tax deadline? Our expedited service delivers fully engineered cost segregation studies in as little as one week, prioritized to meet your Oregon filing requirements.

Frequently Asked Questions

What is a cost segregation study and how does it work?

A cost segregation study is an engineering-based tax analysis that reclassifies components of your real property — such as flooring, lighting, landscaping, and specialty equipment — into shorter depreciation categories of 5, 7, or 15 years, instead of the standard 27.5 or 39 years. This accelerates your depreciation deductions, significantly reducing your taxable income in the early years of ownership and freeing up cash for reinvestment.
