Rental Property Depreciation: How It Works and What It Saves You (2026)

Rental property depreciation is the single biggest tax advantage of owning rental real estate — and the one most owners understand least. It’s a paper deduction: the IRS lets you write off the cost of the building a little each year, even as the property appreciates in value and generates cash. Done right, depreciation can shelter much or all of your rental income from tax. Done wrong — or ignored — it can leave money on the table and still create a tax bill when you sell. This guide explains exactly how it works, walks a real example, and covers the part nobody warns you about: depreciation recapture.

This is general information based on common scenarios — not tax advice. Depreciation rules, basis allocation, recapture, and bonus-depreciation percentages are technical and change with the tax law. Confirm everything here with a CPA before you file. Figures and rates are directional; verify current ones.

What rental property depreciation actually is

Depreciation is the IRS’s way of letting you recover the cost of a wearing asset over time. The theory: a building physically deteriorates — roof, structure, systems — so the tax code lets you deduct a slice of its cost each year as a non-cash expense. The reality for a landlord is more powerful than the theory: in most markets the property appreciates while you’re taking the deduction, so you’re writing off the cost of an asset that’s actually gaining value.

That’s what makes depreciation the headline tax benefit of rental real estate. It’s a deduction you take without spending a dollar. Your mortgage interest, property tax, insurance, repairs, and management fees are real cash leaving your account. Depreciation is a deduction layered on top that costs you nothing in cash — it simply reduces the income the IRS taxes.

Three foundational rules before the mechanics:

• You depreciate the building, never the land. Land doesn’t wear out, so it isn’t depreciable. This is the allocation step most DIY filers get wrong.
• You depreciate over a fixed schedule. Residential rental is 27.5 years; commercial is 39 years. The method is straight-line under MACRS.
• You start when it’s “placed in service.” Ready and available to rent, not when you closed or when a tenant arrives.

For where depreciation fits among the broader tax advantages of holding rentals in an entity, see tax benefits of LLC for rental property.

The 27.5-year schedule and straight-line MACRS

Residential rental property uses the Modified Accelerated Cost Recovery System (MACRS), but for the building itself the recovery is straight-line over 27.5 years — meaning you deduct the same amount each full year (the first and last years are partial, using a mid-month convention).

The math is simple once you have the depreciable basis (the building’s allocated value):

Annual depreciation = Depreciable basis ÷ 27.5

That’s roughly 3.636% of the building’s value per year. A building portion worth $220,000 yields about $8,000/year in depreciation deductions for 27.5 years.

A few mechanics that matter:

• Mid-month convention. In the year you place the property in service, you get a partial year’s depreciation based on the month it went into service (you’re treated as placing it in service mid-month). The same applies in the year you sell.
• Straight-line, not accelerated, for the building. The “accelerated” in MACRS applies to shorter-life components (appliances, carpet, land improvements), not the 27.5-year structure. The building grinds down evenly.
• 27.5 years is residential; 39 is commercial. A pure residential rental is 27.5. Mixed-use and commercial shift to 39. Confirm classification with your CPA.

Property type	Recovery period	Method	Approx. annual rate
Residential rental building	27.5 years	Straight-line MACRS	~3.636%
Commercial building	39 years	Straight-line MACRS	~2.564%
Appliances, carpet, furniture	5 years	MACRS (accelerated)	front-loaded
Office/desk-type personal property	7 years	MACRS (accelerated)	front-loaded
Land improvements (fences, paving)	15 years	MACRS (accelerated)	front-loaded
Land	Not depreciable	—	0%

That last row is the whole game: separating land from building, and then optionally separating shorter-life components from the building (that’s cost segregation, below).

Finding your depreciable basis (building vs. land)

This is the step that decides your deduction, and the one to get right. Your depreciable basis is generally what you paid for the property (purchase price plus certain closing costs and capital improvements), minus the value of the land.

The standard process:

1. Start with your cost basis. Purchase price + qualifying acquisition closing costs (title, recording, legal, transfer taxes) + capital improvements made before placing it in service.
2. Subtract the land value. Land isn’t depreciable, so you allocate the basis between land and building.
3. The result is your depreciable basis — the building portion you divide by 27.5.

How to allocate land vs. building. The most common and defensible method is the county tax assessor’s ratio. Your property tax bill (or assessor’s site) usually lists an assessed value for land and a separate value for improvements (the building). Apply that ratio to your purchase price.

Worked allocation:

• You buy a rental for $300,000.
• The assessor values the property at $250,000 total: $50,000 land / $200,000 improvements — a 20% land / 80% building ratio.
• Apply that ratio to your $300,000 cost: $60,000 land (not depreciable) / $240,000 building (depreciable).
• Annual depreciation = $240,000 ÷ 27.5 = ~$8,727/year.

Other allocation methods exist (a professional appraisal that breaks out land, or insurance replacement-cost data), but the assessor ratio is the workhorse. Don’t lowball the land to inflate depreciation — that’s a red flag the IRS looks for, and it bites you on recapture anyway. Get the allocation reasonable and documented.

A so-called “rental property depreciation calculator” is just this arithmetic: depreciable basis ÷ 27.5, with the mid-month convention in the first and last years. The hard part isn’t the division — it’s nailing the basis and the land allocation.

”Placed in service” — when the clock starts

Depreciation begins when the property is placed in service, defined as ready and available for rent — not when you bought it and not when a tenant signs.

• If you buy a rent-ready house in March and list it for rent that month, it’s placed in service in March even if it sits vacant until June.
• If you buy a property that needs renovation, it’s generally placed in service when the work is done and it’s listed/available to rent, not at closing. The pre-service rehab costs roll into basis rather than being deducted immediately.

Getting the placed-in-service date right matters because the first-year deduction uses the mid-month convention from that date. Document when the property became available to rent (the listing date is good evidence).

A worked example: depreciation in action

Let’s run a full year to show why landlords love this deduction.

The property:

• Purchase price: $300,000, allocated 80/20 → $240,000 building, $60,000 land
• Placed in service January, so a near-full first year
• Annual depreciation: $240,000 ÷ 27.5 = ~$8,727

The cash picture (annual):

• Gross rent: $30,000
• Cash operating expenses (taxes, insurance, repairs, management): −$10,000
• Mortgage interest (deductible): −$12,000
• Pre-depreciation taxable income: $8,000

Now apply depreciation:

• Taxable income before depreciation: $8,000
• Depreciation deduction: −$8,727
• Taxable rental income/(loss): −$727

Look at what happened. The property generated real positive cash flow (rent exceeded cash costs and the cash part of the mortgage payment), yet for tax purposes it shows a small loss — because the $8,727 non-cash depreciation deduction wiped out the taxable income and then some. You pocketed cash and reported a paper loss the IRS may let you use against other income (subject to passive-activity loss rules and income limits — that’s a CPA conversation).

This is the magic of depreciation: it converts a cash-positive rental into a tax-neutral or tax-negative one, deferring tax for as long as you hold. The word “deferring” is doing real work, though — which brings us to the part most owners forget.

Depreciation recapture: the bill that comes due when you sell

Here’s the trade-off the IRS makes with you. It lets you deduct depreciation every year, lowering your taxable income while you hold. In exchange, when you sell, it takes some of that benefit back through depreciation recapture.

How it works for residential rental (Section 1250 property):

• Every year of depreciation lowers your adjusted basis in the property. Take $8,727/year for 5 years and you’ve reduced your basis by ~$43,600.
• A lower basis means a larger gain when you sell.
• The portion of your gain attributable to depreciation you took is taxed as unrecaptured Section 1250 gain, at a federal rate of up to 25% — separate from, and on top of, the long-term capital-gains rate (0/15/20%) that applies to the actual appreciation.

A quick illustration:

• Buy at $300,000, take $43,600 of depreciation over 5 years → adjusted basis = $256,400.
• Sell for $360,000.
• Total gain = $360,000 − $256,400 = $103,600.
• Of that, $43,600 is unrecaptured Section 1250 gain, taxed at up to 25%.
• The remaining $60,000 (true appreciation) is taxed at long-term capital-gains rates.

So depreciation isn’t free money — it’s a deferral plus a rate arbitrage. You deduct now (often against ordinary income at your marginal rate) and pay recapture later (capped at 25%). For most investors that’s still a strong deal: you get the deduction’s use for years, the rate is capped, and you can often defer recapture entirely with a 1031 exchange.

The trap: “allowed or allowable”

This is the part that catches owners who think skipping depreciation avoids the future tax. The IRS recaptures depreciation “allowed or allowable.” Translation: when you sell, recapture is calculated on the depreciation you could have taken — whether or not you actually claimed it.

So if you never depreciated the property to “keep it simple,” you still owe recapture as if you had — you just never got the deduction. You’d be paying the tax for a benefit you forfeited. That’s the worst of both worlds. Depreciate every year; it’s not optional in any sense that helps you. (If you’ve missed years, a CPA can often fix it with Form 3115 to catch up the deductions.)

Bonus depreciation and cost segregation — front-loading the deduction

Two advanced tools let you accelerate depreciation well beyond the steady 27.5-year drip.

Cost segregation is an engineering-based study that breaks your property into components by useful life. Instead of depreciating everything over 27.5 years, a cost-seg study reclassifies portions into 5-year (appliances, carpet, certain fixtures), 7-year, and 15-year (land improvements like paving, landscaping, fencing) buckets — all of which depreciate far faster than the building. The result is much larger deductions in the early years of ownership. For the full mechanics and when a study pays for itself, see cost segregation for real estate.

Bonus depreciation supercharges this. When components are reclassified into shorter-life categories via cost seg, a percentage of their value can be deducted immediately in year one under bonus depreciation rules. Bonus has been phasing down from 100% — verify the current-year percentage with your CPA, since the figure changes by tax year and has been subject to legislative changes. Combined, cost seg + bonus can turn a modest first-year deduction into a very large one.

The honest caveats:

• It accelerates, it doesn’t multiply. Front-loading deductions you’d otherwise spread over decades. You’re pulling future deductions into today.
• Recapture stakes rise. More (and faster) depreciation means more to recapture on sale — and the shorter-life personal property is recaptured at ordinary rates under Section 1245, not the 25% Section 1250 cap. A 1031 exchange and hold strategy mitigates this.
• There’s a cost and complexity layer. Cost-seg studies aren’t free, and they pencil best on higher-value properties held long enough to use the deductions. This is firmly CPA territory.

How an LLC interacts with depreciation

A common question: does putting the rental in an LLC change depreciation? For tax purposes, generally no — and that’s a feature.

• A single-member LLC is disregarded by default: depreciation flows to your Schedule E exactly as if you owned the property personally.
• A multi-member LLC files a partnership return (Form 1065); depreciation is computed at the entity level and passed through to members on K-1s.

The LLC is a liability shield, not a tax shelter — it doesn’t add or subtract depreciation. You get the same 27.5-year deduction either way. What the LLC adds is asset protection: it walls off your personal assets from claims arising at the property. So you don’t choose between depreciation and an LLC — you get the tax benefit and the liability protection together. For the protection side, see should you put your rental property in an LLC.

Common depreciation mistakes

• Not depreciating at all. “Allowed or allowable” means you’ll owe recapture as if you did — depreciate every year or you pay the tax for a deduction you never used.
• Depreciating the land. Land isn’t depreciable. Failing to back out land overstates your deduction and invites an adjustment.
• Lowballing land to inflate the building. A red flag the IRS watches for, and it just increases your recapture later. Use a defensible ratio (assessor’s is standard).
• Wrong placed-in-service date. It’s when the property is ready and available to rent, not closing day or move-in day.
• Forgetting recapture in the sale math. Depreciation is a deferral, not free money. Model the up-to-25% recapture before you sell — or plan a 1031 exchange.
• DIY cost seg or bonus depreciation. These are powerful but technical, with real recapture and audit considerations. Use a CPA and, for cost seg, a qualified study.

FAQ

Frequently asked questions

How does rental property depreciation work? +

You deduct the cost of the building (not the land) over 27.5 years using straight-line MACRS — roughly 3.636% of the building's value each year against your rental income. It's a non-cash deduction, so it reduces taxable income without costing you anything. Depreciation starts when the property is placed in service (ready and available to rent) and continues until you've fully depreciated the building or sell.

How do I calculate depreciation on a rental property? +

Take your cost basis (purchase price plus qualifying closing costs and pre-service improvements), subtract the land value to get your depreciable basis, then divide by 27.5 for the annual deduction. To split land from building, most investors use the county assessor's land-to-improvement ratio applied to the purchase price. The first and last years are partial under the mid-month convention. A CPA should confirm your basis and allocation.

Why can't I depreciate the land under my rental? +

Depreciation recovers the cost of an asset that wears out over time, and land doesn't deteriorate — so the tax code treats it as non-depreciable. You must allocate your purchase price between land and building and depreciate only the building portion. Skipping this and depreciating the whole purchase price overstates your deductions and is a common IRS adjustment.

What is depreciation recapture on a rental property? +

When you sell, the depreciation you took lowered your basis and therefore increased your gain. The portion of the gain attributable to that depreciation (unrecaptured Section 1250 gain on residential rental) is taxed at a federal rate of up to 25%, separate from and on top of capital-gains tax on the appreciation. It's the trade-off for deducting depreciation while you held the property — a deferral, not a free deduction.

What happens if I never claimed depreciation on my rental? +

You still owe recapture. The IRS recaptures depreciation 'allowed or allowable,' meaning it's calculated on the depreciation you could have taken whether or not you claimed it. So skipping depreciation doesn't avoid the tax on sale — it just forfeits the yearly deduction. If you've missed years, a CPA can often catch them up using Form 3115. Depreciate every year; not depreciating helps no one.

Can I avoid depreciation recapture? +

You can defer it. A 1031 like-kind exchange rolls the gain (including the depreciation component) into a replacement property, deferring recapture and capital-gains tax. Holding until death can also reset basis for heirs under current step-up rules. Outside those strategies, recapture is generally owed on sale. These are technical, change with the tax law, and require a CPA and often a qualified intermediary to execute.

What's the difference between depreciation and cost segregation? +

Standard depreciation spreads the whole building over 27.5 years. Cost segregation is an engineering study that breaks the property into shorter-life components — 5-year (appliances, carpet), 7-year, and 15-year (land improvements) — that depreciate much faster, front-loading your deductions. Paired with bonus depreciation, a large share can be deducted in year one. It raises the recapture stakes and has a study cost, so it pencils best on higher-value, longer-hold properties.

Does putting my rental in an LLC change depreciation? +

Generally no. A single-member LLC is disregarded for tax, so depreciation flows to your Schedule E exactly as if you owned the property personally; a multi-member LLC computes it at the entity level and passes it through on K-1s. The LLC is a liability shield, not a tax change — you keep the same 27.5-year deduction and add asset protection. So you don't trade one for the other; you get both.

How much will depreciation save me in taxes each year? +

It depends on your building basis and your marginal tax rate. The deduction equals your depreciable basis ÷ 27.5; the tax saved is that deduction times your marginal rate (subject to passive-activity loss rules). A $240,000 building yields ~$8,727/year of deduction, which at a 24% marginal rate saves roughly $2,094/year in tax — while costing you nothing in cash. A CPA can model your specific situation.

Bottom line

Rental property depreciation is the quiet engine of real-estate tax efficiency: a non-cash deduction that lets you write off the building over 27.5 years, often turning a cash-positive rental into a tax-neutral or tax-negative one. The mechanics are simple — depreciable basis (building, not land) divided by 27.5 — but the details decide the outcome: allocate land correctly, nail the placed-in-service date, and depreciate every year.

Just don’t forget the other half of the bargain. Depreciation is a deferral, recaptured at up to 25% when you sell — and the IRS recaptures it whether or not you claimed it, so never skip it. For investors who want to front-load deductions, cost segregation and bonus depreciation accelerate the benefit, at the cost of higher recapture and complexity. And putting the property in an LLC changes none of this — you keep the full deduction and add liability protection.
