Depreciation

Depreciation is a tax deduction that allows short-term rental owners to recover the cost of their property and its improvements over a defined useful life — reducing taxable income each year without any cash outlay. The IRS depreciates residential rental buildings over 27.5 years, making this phantom deduction one of the most valuable financial levers available to Airbnb hosts and STR investors. On a $400,000 property, the building component alone generates roughly $11,000–$13,000 in annual deductions before a single receipt is filed.

Key Takeaways

• Residential rental buildings depreciate over 27.5 years; furnishings and appliances over 5-7 years, starting the month a property is placed in service
• Depreciation is a non-cash deduction — it reduces taxable income without requiring any out-of-pocket payment
• STR hosts who meet the material participation or real estate professional tests can apply depreciation losses directly against W-2 and other active income
• Cost segregation studies reclassify 20-40% of building value into 5- or 15-year schedules, dramatically front-loading deductions
• Depreciation is recaptured at up to 25% on sale, but a 1031 exchange defers that tax indefinitely

How Depreciation Works for Rental Properties

Standard Depreciation Schedules

Asset Type	Useful Life	Annual Deduction Rate
Residential building (structure)	27.5 years	3.636% of basis per year
Appliances and equipment	5 years	20% per year (straight-line)
Furniture and fixtures	7 years	14.29% per year (straight-line)
Land improvements (landscaping, driveways)	15 years	6.67% per year
Land	Not depreciable	N/A

The clock starts the month the property is first rented — not the month of purchase. A property acquired in December and listed in January begins depreciating in January.

Calculating Annual Depreciation

Step 1: Establish the depreciable basis — purchase price minus the land value allocation.

Step 2: Divide the building basis by 27.5; add separate calculations for personal property (5-7 years).

Example — $450,000 property:

Item	Amount
Purchase price	$450,000
Land value (20% allocation)	-$90,000
Building depreciable basis	$360,000
Annual building depreciation (÷ 27.5 yrs)	$13,091
Furnishings and setup costs	$30,000
Annual furnishing depreciation (5-7 yrs)	$4,286–$6,000
Total annual depreciation	$17,377–$19,091

At a 32% marginal tax rate, this saves $5,561–$6,109 per year in taxes — without spending a dollar.

The Tax Savings Math by Bracket

Tax Bracket	Annual Depreciation	Annual Tax Savings	10-Year Cumulative
22%	$15,000	$3,300	$33,000
24%	$15,000	$3,600	$36,000
32%	$15,000	$4,800	$48,000
35%	$15,000	$5,250	$52,500
37%	$15,000	$5,550	$55,500

Higher-bracket investors capture the most absolute value, but depreciation is worth claiming at every bracket — it is the only major real estate deduction that requires zero spending to earn.

Accelerated Depreciation: Bonus Depreciation and Cost Segregation

Standard straight-line depreciation is conservative. Two tools let STR owners take far larger first-year deductions:

Bonus Depreciation

Bonus depreciation allows an immediate deduction on a fixed percentage of eligible 5-, 7-, or 15-year property in the year it is placed in service. The rate phases down under current law: 80% in 2023, 60% in 2024, 40% in 2025, 20% in 2026, then 0% from 2027 onward unless Congress extends it. Furnishings, appliances, and most cost-segregated components qualify.

On $30,000 in furnishings in 2026, a 40% bonus depreciation rate means a $12,000 first-year deduction — instead of $4,286–$6,000 spread across 5-7 years.

Cost Segregation

Cost segregation is an engineering study that reclassifies portions of a building from 27.5-year real property into 5-year, 7-year, or 15-year personal property and land improvements. Components that typically qualify include carpet, specialty lighting, decorative finishes, HVAC systems, and outdoor features. Studies typically cost $3,000–$10,000 but can generate $50,000–$150,000 in additional first-year deductions on a $400,000–$700,000 STR property.

Depreciation — and especially accelerated depreciation — is the mechanism that lets a profitable short-term rental produce a paper tax loss even in years when it generates strong cash flow. That combination of taxable loss and real income is the core of STR as a wealth-building vehicle.

Material Participation: Unlocking STR Depreciation Against Active Income

By default, rental income is passive, and passive losses (including depreciation) can only offset other passive income. Two pathways override that rule for STR investors:

Real estate professional status: Spend more than 750 hours per year in real-estate-related activities and more time in real estate than in any other profession. Losses become active, fully offsetting W-2 income without limit.

STR material participation: Short-term rentals with an average guest stay of 7 days or fewer are not automatically classified as passive activity under IRC §469. An STR host who materially participates in the rental (100+ hours, more than anyone else, or one of five other tests) can deduct depreciation losses against ordinary income regardless of professional status.

The STR investment analysis guide walks through how to document material participation so these deductions survive IRS scrutiny.

Depreciation Recapture: The Exit Cost

Every depreciation dollar claimed (or that should have been claimed) is subject to recapture at sale. The IRS taxes recaptured depreciation at a maximum 25% rate — higher than the standard 15-20% long-term capital-gains rate.

Example: $80,000 in cumulative depreciation → up to $20,000 in recapture tax at sale.

The standard mitigation strategy is a 1031 exchange, which defers both the capital gain and the recapture tax by rolling proceeds into a like-kind replacement property. Investors who hold STRs for decades and exchange repeatedly can defer recapture indefinitely — effectively converting it into a step-up in basis for heirs.

The DSCR financing landscape in 2026 is relevant here: investors who use DSCR loans to acquire replacement properties can complete a 1031 exchange without showing W-2 income, making the deferral accessible even to full-time STR operators.

Why Depreciation Matters for Airbnb Hosts

• Tax-free income shelter: In markets where STR revenue is strong — AirROI data shows Nashville median revenue at $44,039 and Scottsdale at $49,153 per year — depreciation can shelter 30–50% of gross income from tax, dramatically improving after-tax returns
• Phantom deduction: Unlike operating expenses such as cleaning and supplies, depreciation costs nothing out of pocket while still reducing taxable income
• Portfolio compounding: Tax savings from depreciation can fund down payments on additional properties, accelerating portfolio growth without external capital
• Competitive advantage: Full-time STR investors who understand depreciation mechanics — especially cost segregation and bonus depreciation — routinely outperform investors who treat rentals as passive income plays

Airbnb vs. long-term rental comparison shows how depreciation often tips the after-tax return decisively in favor of STR even in markets where gross revenue gaps are modest.
