Illinois's diverse rental market–from Chicago's urban multifamily to suburban single-family rentals across Naperville and Aurora–offers varied opportunities for real estate investors. A cost segregation study can help Illinois property owners accelerate depreciation and improve cash flow. SMF Cost Segregation Advisors delivers thorough, IRS-ready studies designed to maximize tax savings across Chicago and Illinois investment properties.
In Illinois, the most common candidates are single-family rentals, duplexes, triplexes, fourplexes, and small apartment buildings (1-10 units). Properties with extensive site improvements–such as parking lots, landscaping, fencing, and outdoor amenities–tend to yield the highest percentage of accelerated depreciation.
Yes, provided the depreciable building basis (purchase price minus land value) is at least $150,000-$200,000. With 100% bonus depreciation now permanent, the first-year tax savings on a single Illinois property often exceed the study cost by 5-10x.
You'll need the property address, original purchase price or closing statement, the date it was placed in service as a rental, and any renovation invoices. Building plans are helpful but not required–our engineering team can work from a virtual walkthrough for Illinois properties.
Federal cost segregation benefits are calculated at the federal level. However, Illinois may or may not conform to federal bonus depreciation rules. In non-conforming states, you may need two depreciation schedules. Your CPA can determine Illinois's current conformity status.
The tax savings are realized when you file your tax return for the year the study applies to. For look-back studies on older Illinois properties, the catch-up deduction is claimed on the current year's return via Form 3115.
For Illinois investors, the typical ROI ranges from 5x to 20x the cost of the study, depending on property value and type. A single-family rental with a $300,000 building basis might generate $20,000-$30,000 in first-year tax savings from a study costing $1,750-$2,750.
