Depreciation on Rental Property: How It Works and Why It Matters

What Is Rental Property Depreciation?

The IRS lets you deduct the cost of a rental building over time, even if the property is actually going up in value. This is a paper loss — you’re not spending any extra money, but you get to reduce your taxable rental income as if you were.

Here’s the logic: the IRS considers buildings to have a finite useful life. Roofs wear out. Plumbing corrodes. HVAC systems break down. So they allow you to write off the building’s cost gradually, reflecting that theoretical wear and tear.

The key distinction: you depreciate the building only, not the land. Land doesn’t wear out. So you need to separate the two values before calculating anything.

For most rental property owners, depreciation is the single largest tax deduction available. It often turns a property that generates positive cash flow into one that shows a loss on paper — which means you could owe little or no tax on that rental income. Combined with other rental property tax deductions, this can dramatically reduce your effective tax rate.

Depreciation applies to any property “placed in service” as a rental. The day a tenant moves in or the property is listed for rent, the depreciation clock starts. You don’t need to wait until January — it begins mid-year if that’s when you start renting.

How to Calculate Depreciation on a Rental Property

The standard calculation for residential rental property follows three steps.

Determine Your Cost Basis

Your cost basis is what you paid for the property, including closing costs that get capitalized: title insurance, legal fees, recording fees, and transfer taxes. It does not include prepaid items like property tax prorations or insurance.

If you bought a duplex for $300,000 with $5,000 in capitalizable closing costs, your cost basis is $305,000.

Subtract the Land Value

The IRS requires you to separate land from building value. Most investors use one of these methods:

• Tax assessor allocation — your county assessment breaks out land vs. improvements. If the assessment shows 20% land and 80% building, apply those percentages to your purchase price.
• Appraisal — a formal appraisal that separates land and building values. More defensible in an audit.
• Insurance replacement cost — your insurance policy covers the building replacement cost, not land. This gives a reasonable building value.

Using our example: $305,000 cost basis with 20% allocated to land = $61,000 land. That leaves $244,000 as the depreciable basis.

Divide by 27.5 Years

Residential rental property depreciates over 27.5 years using the straight-line method (equal amounts each year). This timeline comes directly from IRC Section 168(c).

$244,000 / 27.5 = $8,873 per year in depreciation deductions.

That’s $8,873 you get to subtract from your rental income every year for 27.5 years — without spending a single additional dollar. This deduction shows up on Schedule E of your tax return.

There’s one wrinkle: the IRS uses a mid-month convention for the first year. If you place the property in service in July, you only get 5.5 months of depreciation that first year (July through December, counting July as half). The final year gets the remaining half-month.

Depreciation Schedules by Property Type

Not everything depreciates over 27.5 years. The IRS assigns different useful lives based on asset type.

These shorter-life assets matter because you can either depreciate them on their assigned schedule or, in many cases, apply bonus depreciation to write them off even faster. A cost segregation study identifies and reclassifies building components into these shorter categories.

Depreciation Recapture: The Tax Bill When You Sell

Depreciation isn’t free money — the IRS collects its share when you sell. This is called depreciation recapture, governed by Section 1250 of the tax code.

When you sell a rental property, the IRS taxes all the depreciation you claimed (or could have claimed, even if you didn’t) at a flat 25% rate. This is separate from any capital gains tax on the property’s appreciation.

Here’s what that looks like in practice:

• You bought a property for $300,000 (with $240,000 depreciable basis)
• You held it for 10 years and claimed $87,273 in depreciation ($8,727/year)
• You sell for $400,000
• Adjusted basis: $300,000 – $87,273 = $212,727
• Total gain: $400,000 – $212,727 = $187,273
• Depreciation recapture: $87,273 x 25% = $21,818 in recapture tax
• Remaining capital gain: $100,000 taxed at long-term capital gains rates (0%, 15%, or 20%)

Important: you owe recapture tax on depreciation you could have taken, even if you never claimed it. The IRS doesn’t let you skip depreciation deductions and then sell without recapture. So always take the depreciation — there’s no benefit to leaving it on the table.

There are two main ways to defer or avoid recapture:

• 1031 exchange — swap into another investment property and defer all gain and recapture taxes indefinitely. Learn the full process in our 1031 exchange guide.
• Step-up in basis at death — if you hold the property until death, your heirs receive a stepped-up basis equal to fair market value. All accumulated depreciation and gains are wiped clean.

Bonus Depreciation and Cost Segregation

Standard depreciation spreads deductions evenly over 27.5 years. Bonus depreciation lets you front-load a massive chunk of those deductions into year one — but only for assets with recovery periods of 20 years or less.

That’s where cost segregation enters the picture. A cost segregation study, conducted by an engineer, reclassifies building components into shorter-life categories. Instead of depreciating the entire building over 27.5 years, portions get moved into the 5-year, 7-year, or 15-year buckets — and those reclassified assets qualify for bonus depreciation.

The rate depends on when the property was acquired. The One, Big, Beautiful Bill Act made the 100% additional first-year (“bonus”) depreciation deduction permanent for qualified property acquired after January 19, 2025, per IRS Notice 2026-11 (January 2026). Property acquired before that date still falls under the older TCJA step-down:

On a $500,000 rental property, a cost segregation study might reclassify 25-30% of the building cost ($125,000-$150,000) into shorter-life categories. At 100% bonus depreciation, that’s $125,000-$150,000 in first-year deductions on top of regular depreciation. At a 37% marginal tax rate, that saves $46,250-$55,500 in year one alone.

Cost segregation studies run $5,000 to $15,000 depending on property size and complexity. The ROI is often 5x to 10x the study cost. Read the full breakdown in our cost segregation study guide.

This strategy pairs particularly well with real estate professional status, which allows you to use rental losses (including depreciation) to offset W-2 income.

How Depreciation Creates Tax-Free Cash Flow

This is where depreciation becomes genuinely powerful. The gap between actual cash flow and taxable income is where the tax magic happens.

Let’s walk through a real example:

You put $12,000 of real cash in your pocket, but you only owe tax on $3,273. At a 24% marginal rate, that’s $786 in federal tax on $12,000 of income — an effective rate of 6.5%.

With a cost segregation study or higher-value property, the depreciation deduction can exceed cash flow entirely, creating a tax loss on paper even though you’re making money. That paper loss can offset other passive income if you have it, or get carried forward to future years.

For those who qualify as a real estate professional, those paper losses can offset active income — your salary, business income, or self-employment earnings. That’s the strategy high-income investors use to bring their effective tax rate well below their marginal bracket.

This dynamic is one of the primary reasons real estate remains attractive to investors compared to stocks, bonds, or other asset classes. No other mainstream investment offers this combination of cash flow, appreciation, and tax-sheltered income.

Common Depreciation Mistakes to Avoid

After working with hundreds of rental property owners, these are the errors that come up most often.

Not Depreciating at All

Some landlords skip depreciation, thinking they’ll avoid recapture tax when they sell. This doesn’t work. The IRS calculates recapture based on depreciation “allowed or allowable” — meaning what you could have claimed. You’ll owe recapture tax regardless, so take every dollar of deduction available to you.

Depreciating Land

Land is not depreciable. If your entire purchase price is being depreciated without separating the land value, you’re overstating deductions and inviting an audit. Use your county tax assessment, an appraisal, or the insurance replacement cost method to establish the split.

Wrong Placed-in-Service Date

Depreciation starts when the property is placed in service as a rental — not when you buy it, not when renovations finish, but when it’s available for rent. If you bought a property in March and listed it for rent in June, the placed-in-service date is June.

Mixing Improvements with Repairs

Repairs (fixing what’s broken) are deducted fully in the year incurred. Improvements (making something better, longer-lasting, or new) must be capitalized and depreciated. A new roof is an improvement (depreciated). Patching a leaky section is a repair (deducted). Getting this wrong either over- or understates your deductions. Review the details in our rental property tax deductions guide.

Forgetting to Depreciate Improvements

Every capital improvement to a rental starts its own depreciation schedule. New roof in year 5? That’s a new 27.5-year asset. New appliances? Those go on a 5-year schedule. Track each improvement separately — many investors leave thousands in deductions unclaimed because they forget to depreciate upgrades.

Depreciation and Your Investment Strategy

How you approach depreciation should align with your broader investment goals.

Buy-and-hold investors benefit from standard depreciation year after year, steadily sheltering rental income from taxes. Over a 27.5-year holding period, you’ll have deducted the full building value. After that, your taxable income rises because the depreciation deduction disappears — a common trigger for a 1031 exchange into a higher-value property that resets the depreciation clock.

High-income earners should consider accelerated depreciation through cost segregation, especially now that 100% bonus depreciation is permanent for property acquired after January 19, 2025. Pairing this with real estate professional status (or the short-term rental loophole) can shelter hundreds of thousands in W-2 income.

First-time investors buying a single rental should still understand depreciation thoroughly. Even on a modest $200,000 property, you’re looking at $5,800+ per year in deductions. Over 10 years, that’s $58,000 in income you didn’t pay taxes on. Start with the basics in our guide to buying your first rental.

For investors considering entity structuring, depreciation flows through to your personal return regardless of whether you hold the property personally or in an LLC. The entity choice doesn’t change the depreciation calculation — it changes liability protection and how income is reported.

Frequently Asked Questions

Can I depreciate my primary residence?

No. Depreciation is only available for property used in a trade, business, or held for the production of income. Your primary residence doesn’t qualify. If you convert your home to a rental, depreciation begins on the conversion date, using the lesser of your adjusted basis or fair market value at conversion.

What happens when depreciation runs out after 27.5 years?

Your annual depreciation deduction drops to zero, and your taxable income from the property increases by that amount. Many investors use this as a trigger to sell (via 1031 exchange) or refinance. The property itself continues to operate normally — you just lose the tax shelter.

Do I have to use straight-line depreciation?

For the building structure itself, yes — residential rental property must use straight-line over 27.5 years. Shorter-life personal property (appliances, carpet, land improvements) can use accelerated methods like MACRS and may qualify for bonus depreciation.

Can I claim depreciation during vacancies?

Yes, as long as the property is available for rent and you’re actively trying to lease it. A brief vacancy between tenants doesn’t stop depreciation. Extended personal use or taking the property off the rental market does.

Does depreciation reduce my cost basis when I sell?

Yes. Each year of depreciation lowers your adjusted basis in the property. When you sell, the gain is calculated from that lower adjusted basis, increasing both your capital gain and the depreciation recapture amount. This is why some investors plan their exit strategy with a 1031 exchange or hold until the step-up in basis at death.
