Cost Segregation Study in Kansas for Airbnb and Short-Term Rental Investors

Kansas is one of the more favorable states for cost segregation precisely because of how its tax code is structured. Kansas maintains rolling conformity to the Internal Revenue Code, and the state's Schedule S supplemental schedule — where Kansas filers report additions and subtractions from federal adjusted gross income — has no line item requiring individuals or pass-through owners to add federal Section 168(k) bonus depreciation back to Kansas income. In practice, that means Kansas taxable income already reflects whatever bonus depreciation you claimed federally; there's no separate state recapture schedule to track and no multi-year spread-out of an addback like several decoupled states require.

Kansas then goes further than plain conformity. Under K.S.A. 79-32,143a, the state offers an optional 'Kansas expensing deduction,' filed on Schedule K-120EX, for tangible MACRS property with a recovery period of 25 years or less. The deduction equals the depreciable cost remaining after federal bonus depreciation and Section 179 have been applied, multiplied by a statutory 'applicable factor' set out in K.S.A. 79-32,143a(f) that varies depending on the property's depreciation method under IRC Section 168(b)(1), (2), (3), or (g) and its recovery period — so the write-off is not automatically equal to 100% of whatever basis is left. The statute specifically excludes 'residential rental property, nonresidential real property... or any other property with an applicable recovery period in excess of 25 years,' meaning it can never reach the 27.5- or 39-year building shell itself. It is, in effect, written for the exact 5-, 7-, and 15-year components — flooring, cabinetry, decorative lighting, fencing, parking areas, landscaping — that a cost segregation study pulls out of that shell. Owners who never separately identify those components typically have nothing left to claim this Kansas-only deduction against.

Property taxes are a separate consideration but still relevant to the overall math. Kansas's statewide average effective property tax rate on owner-occupied housing runs about 1.2% of assessed value, though county mill levies vary a great deal — Johnson County (home to Overland Park and Olathe) has the state's highest median property tax bill, roughly $4,400 to $4,800 per year according to 2025-2026 SmartAsset data, reflecting the county's higher median home values relative to more rural Kansas counties. That tax bill doesn't change based on how you depreciate the property, but it's useful context for the overall carrying cost an investor is weighing against the income-tax savings a study can unlock.

Without a study, the IRS default is straight-line depreciation: 27.5 years for a residential rental property, 39 years for a commercial building, spread evenly regardless of how quickly individual components actually wear out. A cost segregation study is an engineering-based analysis — typically involving a site visit, review of construction or purchase documents, and a component-by-component cost allocation — that identifies which parts of the property qualify for much shorter IRS-recognized recovery periods of 5, 7, or 15 years. Those categories commonly include removable flooring, decorative millwork and fixtures, specialty electrical and plumbing runs tied to appliances, exterior signage, fencing, and land improvements like paving, curbing, and landscaping.

Before mid-2025, only a declining percentage of that reclassified basis qualified for full first-year bonus depreciation, with the remainder phasing down year over year. That changed with the One Big Beautiful Bill Act, signed into law in July 2025: it permanently restored 100% bonus depreciation for qualifying property acquired and placed in service after January 19, 2025, subject to binding-contract acquisition-date rules, with a transitional election available for some property acquired before that date but placed in service later. For a Kansas property that qualifies, the 5-, 7-, and 15-year assets a study identifies can generally be written off in full in the year the property is placed in service, rather than trickling out over a decade.

For illustration only — your results depend on your property and tax situation, and this is not a projection of actual savings.

Suppose an investor buys a $500,000 short-term rental in Overland Park, allocating roughly $100,000 to land (which is never depreciable) and $400,000 to the structure and its contents. Under standard straight-line depreciation over 27.5 years, that $400,000 produces a first-year deduction of only around $14,500. A cost segregation study might instead reclassify approximately $100,000 of that basis — flooring, cabinetry, appliances, lighting, fencing, the parking pad, and landscaping — into 5-, 7-, and 15-year property. Under the OBBBA's 100% bonus depreciation for qualifying property acquired and placed in service after January 19, 2025, that entire $100,000 could potentially be deductible in year one instead of over multiple decades. Because Kansas doesn't require a bonus-depreciation addback, that same $100,000 would generally reduce Kansas taxable income as well. Actual reclassification percentages, qualifying amounts, and tax savings depend on the property's engineering study, purchase price allocation, and the owner's individual tax situation — a CPA should confirm the numbers before you file.

Cost segregation isn't limited to the year you close on a property. If you already own a Kansas rental — whether it's been in service for one year or fifteen — you can commission a 'look-back' study that captures the same component reclassification retroactively. The mechanism is a Form 3115, Application for Change in Accounting Method, filed with your federal return; it triggers a Section 481(a) adjustment that lets you claim the entire cumulative catch-up depreciation you missed in prior years as a single deduction in the current tax year, without amending any past returns. Because Kansas taxable income begins from federal adjusted gross income and Kansas imposes no separate bonus-depreciation addback, that federal catch-up deduction generally carries through to your Kansas return as well, subject to the same documentation a CPA would expect for any depreciation change.

• Short-term rental and Airbnb hosts operating in markets such as Overland Park, Wichita, Lawrence, and Manhattan, or the Kansas side of the Kansas City metro (Wyandotte and Johnson counties)
• Long-term, buy-and-hold rental owners across the state, from single-family rentals in suburban Johnson County to multifamily properties in Wichita or Topeka
• Investors who recently purchased, built, or substantially renovated a Kansas rental property and haven't yet had a cost segregation study performed
• High-income owners evaluating the short-term rental material participation strategy who need real, substantiated losses to offset W-2 or other active income
• Owners of older Kansas properties who assume it's too late to benefit — a look-back study under Form 3115 can often still capture depreciation that was missed in earlier years
