Depreciation (Real Estate)

Quick Definition

Real estate depreciation (also called cost recovery) is a tax deduction that allows property owners to gradually deduct the cost of an income-producing property from their taxable income over the property's IRS-defined useful life: 27.5 years for residential rental properties and 39 years for commercial properties. It is a non-cash deduction: you receive a tax benefit without spending any money in the current year, making it one of the most powerful tax advantages in real estate investing.

What It Means

Depreciation is the single most important tax benefit in rental real estate. It allows you to report lower taxable income than the cash you actually received, in many cases turning a property that is cash-flow positive into a tax loss on paper. For investors in high tax brackets, depreciation can eliminate or greatly reduce the tax on rental income, dramatically improving after-tax returns.

A major change arrived in July 2025 when the One Big Beautiful Bill Act (OBBBA) made 100% bonus depreciation permanent for qualified property acquired and placed in service after January 19, 2025. The IRS followed up with Notice 2026-11 in January 2026, providing interim guidance on the permanent reinstatement. This reversed the TCJA phase-down schedule that had reduced bonus depreciation from 100% in 2022 to 40% in early 2025, and transforms cost segregation from a useful tactic into an essential strategy for real estate investors.

The Mechanics of Depreciation

Residential rental property:

• Depreciable basis = purchase price + acquisition costs - land value (land is not depreciable)
• Recovery period: 27.5 years
• Method: Straight-line (equal deduction each year)

Annual depreciation = Depreciable basis / 27.5 years

Example: $500,000 residential rental:

Depreciation's Tax Impact: A Real Example

Property: $500,000 rental, 20% down, $2,500/month rent

Without depreciation, there is already a small paper loss. With depreciation, a $30,000 revenue property generates a $17,836 paper loss, potentially offsetting other income and saving $4,000 to $7,000 in taxes annually depending on your bracket.

Passive Activity Rules: Who Can Use Depreciation Losses

IRS passive activity rules limit who can use rental losses against ordinary income:

Real Estate Professional status requires more than 50% of working hours and 750+ hours/year in real estate activities. When met, all rental losses are deductible against any income, an enormous tax benefit that high-income investors specifically structure their lives around.

Cost Segregation: Accelerating Depreciation

Standard depreciation spreads the deduction over 27.5 or 39 years. Cost segregation is a tax strategy that reclassifies components of a building into shorter-life categories:

A cost segregation study on a $1,000,000 commercial property might reclassify $200,000 as 5-7 year property, accelerating $200,000 of deductions from over 39 years to 5-7 years. With 100% bonus depreciation now permanent, those reclassified components can be fully expensed in year one.

The 100% Bonus Depreciation Comeback (2025-2026)

The Tax Cuts and Jobs Act (2017) introduced 100% first-year bonus depreciation on qualified property (5-15 year class lives). The original schedule phased down by 20 percentage points per year:

The OBBBA, signed July 4, 2025, replaced this phase-down with a permanent 100% deduction for qualified property acquired and placed in service after January 19, 2025. There is no scheduled phase-out under current law.

The Two-Track System in 2026

Property placed in service in 2026 falls into one of two tracks depending on acquisition timing:

This means a property placed in service in 2026 can still qualify for full 100% bonus depreciation on its short-life components, as long as the acquisition date falls after January 19, 2025.

What This Means for Cost Segregation

Cost segregation identifies 5, 7, and 15-year components eligible for immediate expensing. The building structure (27.5 or 39 years) does not qualify for bonus depreciation. Without a cost segregation study, the IRS has no documented basis for treating building components as anything other than 27.5 or 39-year property.

On a $3 million commercial building, a study might reclassify $600,000 to 5- or 15-year property, all eligible for immediate write-off at 100%. This can more than double first-year tax savings compared to the 40% bonus rate that applied in early 2025.

Depreciation Recapture: The Tax Bill at Sale

When you sell a depreciated property, the IRS recaptures all depreciation previously taken:

Recapture tax rate: 25% (Section 1250 unrecaptured depreciation)

Example: held 10 years, took $148,360 in depreciation:

• Depreciation recapture tax: $148,360 x 25% = $37,090
• Long-term capital gains on appreciation: additional tax

This is why 1031 exchanges are so powerful. By exchanging instead of selling, depreciation recapture is deferred indefinitely.

The Section 163(j) Trade-Off

Real estate investors using cost segregation should be aware of the Section 163(j) interaction. Section 163(j) limits the business interest deduction to 30% of adjusted taxable income. For highly leveraged investors, this limit often binds.

Real estate businesses can make a real property trade or business election under Section 163(j)(7)(B) to remove the interest limit. The price for this election: you must depreciate residential property over 30 years instead of 27.5, nonresidential property over 40 years instead of 39, and Qualified Improvement Property (QIP) loses bonus depreciation eligibility. Investors must weigh the value of full interest deductibility against the cost of slower depreciation and lost bonus depreciation on QIP.

Key Points to Remember

• Annual depreciation = depreciable basis (excluding land) / 27.5 years (residential) or / 39 years (commercial)
• Depreciation is non-cash; you get a tax deduction without spending money
• Creates a paper loss that reduces taxable rental income, sometimes to zero or below
• Passive activity rules limit loss deductions for high-income investors unless they qualify as Real Estate Professionals
• Cost segregation accelerates depreciation by reclassifying short-life components
• The OBBBA (July 2025) made 100% bonus depreciation permanent for property acquired and placed in service after January 19, 2025
• Depreciation recapture at 25% is owed at sale; deferred via 1031 exchange

Common Mistakes to Avoid

• Not taking depreciation because you do not want to: You will owe depreciation recapture tax at sale on the depreciation you were "allowed or allowable," whether you actually claimed it or not. The IRS taxes you as if you took the deduction. Not taking depreciation saves no tax at sale but costs you the annual deduction. Always take depreciation on investment property.
• Getting the land allocation wrong: More structure means more depreciation. In high-cost urban markets, land may be 30-40% of value; in rural areas, 10-15%. Use the county property tax assessment ratio or an appraisal to establish land value. Getting this allocation right matters.
• Skipping the cost segregation study: Without a formal engineering-based study, the IRS has no documented basis for treating building components as shorter-life property. Skip the study and you leave the 100% bonus deduction on the table.
• Ignoring the Section 163(j) election trade-off: If you make the real property trade or business election to remove the interest deduction limit, you lose bonus depreciation on QIP and must use longer recovery periods. Model both scenarios before electing.
• Forgetting about state conformity: Many states decouple from federal bonus depreciation rules. Your federal deduction may be 100% in year one, but your state may require standard MACRS depreciation. Check your state's conformity rules before projecting after-tax returns.

Frequently Asked Questions

Q: Do I have to take depreciation if I do not want to? A: No, but you will owe depreciation recapture tax at sale on the depreciation you were "allowed or allowable," whether you actually claimed it or not. The IRS taxes you as if you took the deduction. Not taking depreciation saves no tax at sale but costs you the annual deduction, the worst of both worlds. Always take depreciation on investment property.

Q: How is land value determined for depreciation? A: Land value is typically determined using the county property tax assessment ratio between land and improvements. If the assessment shows 20% land and 80% structure, apply those percentages to the purchase price. Alternatively, an appraisal can establish land value. In high-cost urban markets, land may be 30-40% of value; in rural areas, 10-15%. Getting this allocation right matters: more structure means more depreciation.

Q: What is the status of bonus depreciation in 2026? A: The OBBBA (signed July 4, 2025) made 100% bonus depreciation permanent for qualified property acquired and placed in service after January 19, 2025. IRS Notice 2026-11 (January 2026) provides interim guidance. Property tied to binding contracts dated on or before January 19, 2025 still follows the old phase-down schedule (20% for 2026). There is no scheduled phase-out under current law for post-January 19, 2025 acquisitions.

Q: What is Section 1250 depreciation recapture? A: Section 1250 recapture applies to real property (buildings). The portion of gain attributable to depreciation previously taken on the structure is taxed at a maximum 25% rate. This is different from Section 1245 recapture (personal property), which is taxed at ordinary income rates. In practice, when you sell a rental property, part of your gain is classified as Section 1250 unrecaptured depreciation (25% tax), and the remaining gain is long-term capital gain (0/15/20% depending on income).

Q: Is cost segregation worth it for a small rental property? A: Cost segregation studies typically cost $3,000 to $10,000 depending on property size and complexity. For a $500,000 rental, the first-year tax savings from 100% bonus depreciation on reclassified components can easily exceed the study cost. For properties under $300,000, the math may not work. Consult a tax professional who specializes in real estate to evaluate your specific situation.
