Cost segregation is a highly effective tax strategy for Illinois property owners. By accelerating depreciation, it can lower taxable income and improve cash flow.
See how much a cost segregation study could save you on a Illinois investment property.
| Property Value | Est. Building Basis | Est. Accelerated Depreciation | Est. Year 1 Tax Savings |
|---|---|---|---|
| $250,000 | $200,000 | $60,000 | $22,200 |
| $375,000 | $300,000 | $90,000 | $33,300 |
| $500,000 | $400,000 | $120,000 | $44,400 |
*Estimates assume 20% land ratio, 30% reclassification rate, and 37% federal tax bracket. Actual results vary.
Most cost segregation providers are built for large commercial projects. We're built for real-world rental investors, including STR operators, single-family rentals, and 5-50 unit small multifamily.
For Illinois property owners, a cost segregation study should deliver results you can trust. Our engineering team produces IRS-compliant reports backed by detailed documentation.
In Illinois, the most common candidates are single-family rentals, duplexes, triplexes, fourplexes, and small apartment buildings (1-50 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.
