Cost Segregation and Allocation Services for Real Estate

A cost allocation plan in real estate serves to systematically categorize and assign property purchase costs to different asset classes based on their useful lives. This strategic allocation allows property owners to accelerate depreciation by identifying components that qualify for shorter recovery periods (5, 7, or 15 years) rather than depreciating the entire property over 27.5 or 39 years. The plan transforms a single lump-sum acquisition into a detailed breakdown of building systems, personal property, land improvements, and structural elements. This creates immediate tax deductions, increases cash flow, and provides IRS-compliant documentation that withstands audit scrutiny while maximizing the financial benefits of real estate ownership.

Yes, cost segregation is completely legal and explicitly supported by the IRS through established tax codes and court precedents dating back decades. The IRS provides detailed guidance in the Cost Segregation Audit Techniques Guide, which outlines proper methodology and compliance standards. Property owners have the legal right to depreciate assets based on their actual useful lives rather than treating entire buildings as single assets. When performed by qualified professionals using engineering-based analysis and proper documentation, cost segregation studies are low-risk, defensible tax strategies. Seneca includes lifetime audit defense with every study, demonstrating our confidence in the legality and compliance of our methodology.

Cost segregation study fees vary based on property size, complexity, and type, typically ranging from $3,000 to $60,000+. Entry properties ($300K-$1M basis) cost $3,000-$12,000 with typical first-year savings of $30,000-$75,000. Medium properties ($1M-$3M) cost $10,000-$20,000 with savings of $75,000-$200,000. Large properties ($3M-$10M) cost $15,000-$30,000 with savings of $200,000-$400,000. Very large properties ($10M+) cost $30,000-$60,000+ with savings exceeding $400,000. The average Seneca client achieves $171,243 in first-year deductions, with ROI typically ranging from 10:1 to 25:1. We provide free preliminary analyses to determine if a study makes financial sense.

Cost segregation applies to any income-producing real estate with a depreciable basis, including single-family homes, multifamily properties, apartment complexes, hotels, office buildings, medical facilities, industrial warehouses, self-storage units, retail centers, restaurants, gas stations, auto dealerships, assisted living facilities, and more. Both newly constructed and acquired properties qualify, as do recently renovated buildings. Properties must be used for business or income generation—personal residences don't qualify unless converted to rental use. The building basis (excluding land value) should typically exceed $300,000 for studies to be cost-effective, though careful analysis of smaller properties may still yield positive returns.

Absolutely. Lookback cost segregation studies allow you to recapture missed depreciation from properties purchased, constructed, or renovated up to 15 years ago without amending prior tax returns. Using IRS Form 3115, you can claim all previously uncaptured accelerated depreciation in a single year, creating substantial immediate tax savings. The process and deliverables mirror current-year studies, including full engineering analysis, comprehensive reporting, and audit defense. Lookback studies cost approximately the same as current-year studies and often provide even greater immediate impact since multiple years of missed deductions are captured at once.

Seneca Cost Segregation completes most studies within 2-4 weeks, significantly faster than the industry standard of 4-8 weeks.
