Million-dollar STR investments generate six-figure tax deductions through cost segregation — enough to meaningfully reshape your tax position for years.
Estimates are for illustration only. Details
Investing $1M in a short-term rental property unlocks the full power of cost segregation. At this price point, the accelerated depreciation reaches $240K — enough to generate approximately $89K in first-year tax savings. For high-income investors in the 37% bracket, this single deduction can eliminate a substantial portion of their federal tax liability.
Properties at the million-dollar level tend to be luxury STRs with extensive buildouts: custom kitchens, high-end appliances, designer furnishings, smart home automation, premium landscaping, pools, and outdoor entertainment areas. Every one of these elements qualifies for accelerated MACRS classification — most in the 5-year class, with site improvements in the 15-year class.
The study cost at $1M is $1,195 — still remarkably affordable relative to the deduction. Many investors at this level work with CPAs who specifically recommend cost segregation as part of a broader tax strategy that includes bonus depreciation, material participation qualification, and strategic timing of property purchases around tax year-end.

Short-term rentals contain a higher concentration of depreciable personal property than almost any other residential property type. Furniture, appliances, linens, kitchenware, electronics, decorative fixtures, and specialty items like hot tubs or game room equipment all qualify as 5-year property under the IRS MACRS classification system. This furniture, fixtures, and equipment (FF&E) component typically represents 15-20% of the depreciable basis.
Beyond interior components, site improvements add additional reclassification value. Driveways, walkways, patios, outdoor lighting, fencing, landscaping, and irrigation systems fall into the 15-year MACRS class rather than the default 27.5-year residential schedule. For STR properties with pools, outdoor kitchens, or fire pits, these components can represent a meaningful share of the total reclassified amount.
With 100% bonus depreciation permanently restored under the One Big Beautiful Bill Act (signed July 2025), every dollar reclassified into 5-year, 7-year, or 15-year MACRS classes is deductible in full in the first year. For STR owners who materially participate in their rental operation, these accelerated deductions can offset W-2 and business income — not just passive rental income.
If your property is a passive investment managed entirely by a third party, the accelerated depreciation may only offset passive income. If your property has minimal furnishings or you plan to sell within 1-2 years, the benefit may be reduced. Actual results vary based on property age, condition, renovations, and local construction costs.

A cost segregation study is an engineering-based analysis that reclassifies components of your property into shorter IRS depreciation categories (5, 7, and 15 years) instead of the default 27.5 or 39 years. This accelerates your depreciation deductions, reducing your tax bill in the early years of ownership.
Short-term rentals are typically furnished with furniture, appliances, electronics, linens, kitchenware, and décor — all of which qualify as 5-year personal property under MACRS. This FF&E (furniture, fixtures, and equipment) often represents 15-20% of the property's depreciable basis, significantly increasing the accelerated depreciation amount compared to unfurnished long-term rentals.
When you sell a property, the IRS recaptures accelerated depreciation at a maximum rate of 25%. However, the time value of money strongly favors taking the deduction now: $50K in tax savings today is worth far more than paying $12,500 in recapture tax years later. Additionally, a 1031 exchange can defer recapture indefinitely.
