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

Nebraska is one of a minority of states where the personal income tax code is written to move automatically with federal law. Under Neb. Rev. Stat. § 77-2714, references to "the laws of the United States" in Nebraska's tax statutes mean the Internal Revenue Code "as the same may be or become effective, at any time or from time to time, for the taxable year" — the definition of rolling, rather than fixed-date, conformity. When the One Big Beautiful Bill Act (OBBBA) restored 100% federal bonus depreciation, Nebraska did not need to pass separate legislation to pick it up; the state simply follows along.

That has not always been the case. For bonus depreciation claimed on assets placed in service after September 10, 2001, Nebraska required individual and corporate taxpayers to add back a share of that federal bonus depreciation and the enhanced Section 179 deduction, then recover that add-back through a five-year subtraction schedule, for tax years beginning before January 1, 2006. The Nebraska Department of Revenue's own guidance confirms that requirement was repealed for tax years beginning on or after January 1, 2006, and has not returned since. For a pass-through owner filing an individual Nebraska return today, this means a cost segregation study's accelerated first-year deduction reduces both federal and Nebraska taxable income in the same year, dollar for dollar, with no reconciliation adjustment to track on the state return.

The payoff is amplified by two other Nebraska realities. First, Nebraska's top individual income tax rate is still 4.55% for 2026 (scheduled to fall to 3.99% in 2027 under LB754), so every dollar of accelerated depreciation still offsets real state tax liability in the near term, not just federal. Second, according to the Tax Foundation's property tax rankings, Nebraska carries one of the higher property tax burdens in the country, with an average effective rate near 1.4% of market value — well above the roughly 0.9% national average. (Nebraska assesses residential real property near 100% of actual value, so the state's assessed-value and market-value rates are close in practice.) Investors who already feel that property tax pressure often find that recovering cash faster through accelerated depreciation, rather than waiting out 27.5 or 39 years of straight-line schedules, meaningfully improves early-year cash flow on a Nebraska rental or Airbnb.

The IRS default for a residential rental building is a 27.5-year straight-line depreciation schedule; a commercial building depreciates over 39 years. Either way, the land underneath is never depreciable, and everything attached to the building — the roof, the HVAC system, the framing — gets lumped into that single long recovery period unless someone breaks it apart. A cost segregation study is an engineering-based analysis that does exactly that: it inspects the property, reviews construction costs or a current appraisal, and separates out components that the IRS actually classifies with shorter recovery periods under Section 1245 and related guidance — items like flooring, cabinetry, decorative and site-specific electrical, appliances, fencing, and land improvements such as parking areas, landscaping, and irrigation. Those components typically fall into 5-year, 7-year, or 15-year classes instead of the 27.5- or 39-year building life.

Why does the reclassification matter so much right now? Because of bonus depreciation. The One Big Beautiful Bill Act, signed into law in July 2025, permanently restored a 100% bonus depreciation rate for qualifying property acquired after January 19, 2025. Any component a cost segregation study identifies as having a recovery period of 20 years or less is eligible for that 100% first-year write-off rather than being depreciated gradually. On a typical rental property, a study often reclassifies somewhere between 20% and 35% of the depreciable building basis into these shorter-lived categories — turning what would have been a decades-long deduction into a single large deduction in the year the property is placed in service.

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

Suppose an investor purchases a short-term rental property in Omaha for $500,000, with $100,000 of that price allocated to land and $400,000 to the building and its components. Under standard straight-line depreciation, that $400,000 building basis would be written off over 27.5 years — roughly $14,500 a year. A cost segregation study on this property might identify around 25% of the building basis, or $100,000, as personal property and land improvements eligible for 5-, 7-, and 15-year treatment: things like appliances, flooring, window coverings, exterior lighting, and driveway paving. Under the OBBBA's 100% bonus depreciation for property placed in service after January 19, 2025, that entire $100,000 could potentially be deducted in year one, instead of trickling out over decades. That is a hypothetical scenario built from round numbers to show the mechanics — actual reclassification percentages, purchase price allocations, and eligible amounts vary property by property and must be verified by an engineer-prepared study and your tax advisor.

Cost segregation is not limited to the year of purchase. If you have owned a Nebraska rental or short-term rental property for one year or longer and never had a study performed, a look-back study can still capture the missed depreciation. Rather than filing amended returns for every prior year, the study is implemented through IRS Form 3115, Application for Change in Accounting Method, which allows the taxpayer to claim the entire cumulative catch-up adjustment under Section 481(a) in a single current-year tax filing. Because Nebraska's income tax follows federal depreciation figures directly under its rolling conformity statute, that same 481(a) catch-up amount carries over onto the Nebraska return without any separate state addition or election, simplifying the process for owners who are catching up on depreciation they left on the table in earlier years.

• Short-term rental and Airbnb hosts in active Nebraska markets such as Omaha, Lincoln, and the Lake McConaughy area around Ogallala, where seasonal demand and strong average daily rates make front-loaded deductions especially valuable
• Long-term rental property owners with single-family homes, duplexes, or small multifamily buildings anywhere in the state, from the Omaha and Lincoln metro areas to smaller Nebraska communities
• Recent buyers and renovators who purchased or substantially remodeled a Nebraska rental property within the last one to two years and have not yet had a cost segregation study performed
• High-income W-2 earners or business owners exploring the short-term rental material participation strategy, which pairs an average guest stay of seven days or less with material participation in the activity to potentially offset active income with rental losses
• Owners nearing a sale or refinance who want to understand their current depreciation position and any potential Section 1250 recapture exposure before making a move
