State Income Tax Rate: 4.95%
Bonus Depreciation Conformity: Does not conform to federal rules
Illinois decoupled from federal bonus depreciation in 2021 (Public Act 102-16). Investors must file Form IL-4562 to add back bonus depreciation and use standard MACRS accelerated methods for state purposes. The federal benefit remains substantial, and the accelerated state depreciation still delivers savings over straight-line.
Rock Island anchors the Quad Cities metro alongside Moline, Davenport, and Bettendorf. The Rock Island Arsenal-the largest government-owned weapons manufacturing facility-employs 6,000+ workers, while Augustana College and the District of Rock Island arts corridor drive rental demand downtown. Broadway and Watch Hill neighborhoods offer affordable duplexes and triplexes, and the Milan Beltway area attracts families seeking value near John Deere's global headquarters in nearby Moline.
Rock Island's Midwest brick construction from the 1920s-1950s contains high-value cost segregation components: tuckpointed masonry, original hardwood, steam heating systems, and detached garages with separate electrical service. Illinois's 4.95% flat income tax and full federal conformity generate dual-level savings. At median prices around $118,000, investors recover the full cost of a study in Year 1, making Rock Island one of the most efficient cost-seg markets in the state.
Rock Island's Arsenal employment and Augustana College create steady rental demand in the Quad Cities.

For Rock Island 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.
For most residential properties in Rock Island, we conduct a virtual site visit via FaceTime or video call. This is faster, less disruptive to tenants, and produces the same quality results as an in-person visit.
The best time is as soon as the property is placed in service or after a major renovation. For Rock Island properties acquired in the current tax year, completing the study before your filing deadline maximizes the first-year benefit.
In Rock Island, the most common candidates are single-family rentals, duplexes, triplexes, fourplexes, and small apartment buildings (1-10 units). Properties with site improvements like parking lots, landscaping, and fencing tend to yield the highest accelerated depreciation.
Yes. Renovation is an ideal time to engage a cost segregation provider. You can segregate both the original building and new renovation costs. Old components being removed may qualify for a Partial Asset Disposition write-off.
Land is non-depreciable, so higher land values reduce the depreciable basis. In high-land-value areas of Rock Island, a $500,000 property might only have a $200,000 building basis. We use defensible methods to establish the land allocation for maximum benefit.
