Depreciation is the most powerful tax benefit available to landlords — and the most commonly misunderstood. It's a non-cash deduction that can shelter $7,000–$15,000 per year in rental income from taxes, even though you never actually wrote a check for it. For a landlord in the 24% tax bracket, that's $1,700–$3,600 in annual tax savings from depreciation alone. Yet many landlords don't fully understand how it works, how to calculate it, or what happens when they sell.

What Is Rental Property Depreciation?

Depreciation is an accounting concept that recognizes physical assets wear out over time. The IRS allows you to deduct a portion of your property's cost each year as a "loss" on your tax return, even though no money left your bank account. This reduces your taxable rental income, which reduces your tax bill.

The key principle: you depreciate the building, not the land. Land doesn't wear out (in the IRS's view), so it's not depreciable. You must separate the purchase price into land value and building value, and only depreciate the building.

The MACRS System: How the IRS Calculates Depreciation

The Modified Accelerated Cost Recovery System (MACRS) is the IRS-required method for depreciating residential rental property placed in service after 1986. Here are the rules:

Residential Rental Property

Commercial Rental Property

"Placed in service" means when it's ready to rent

You begin depreciating property when it's "placed in service" — meaning it's ready and available for renting, not when a tenant actually moves in. If you buy a property on March 15 and spend April renovating, it's placed in service when renovations are complete and the unit is listed for rent. Track this date carefully.

Calculating Depreciation: Step by Step

Step 1: Determine the Cost Basis

Your cost basis is the purchase price plus certain acquisition costs:

Costs that are NOT part of the basis: lender fees, points, appraisal fees, credit report fees. These may be deductible as current expenses or amortized over the loan term.

Step 2: Allocate Between Land and Building

You can only depreciate the building portion. Use one of these methods to allocate:

Example: Using the property tax assessment, land is 20% of total value.

Step 3: Calculate Annual Depreciation

Full-year depreciation: $208,000 ÷ 27.5 = $7,564/year

But the first year uses the mid-month convention, so you get a partial year based on the month placed in service:

MACRS Mid-Month Convention Table (Month Placed in Service)

Example: Property placed in service June 15:

Step 4: Report on Form 4562 and Schedule E

File Form 4562 (Depreciation and Amortization) in the first year to establish the depreciation schedule. In subsequent years, the annual depreciation goes directly on Schedule E, Line 21.

What Can Be Depreciated Beyond the Building

The 27.5-year schedule covers the building structure. But many components of your rental property depreciate faster:

5-Year Property (MACRS)

7-Year Property

15-Year Property

27.5-Year Property

The $2,500 safe harbor for individual items

Under the safe harbor rule, you can expense individual items costing $2,500 or less immediately (deduct in full the year purchased) instead of depreciating. A $1,200 refrigerator? Deduct it now. A $3,000 HVAC component? Depreciate over 5 years (or use cost segregation to accelerate). This safe harbor simplifies accounting for most appliance replacements.

Cost Segregation Studies: Accelerating Depreciation

A cost segregation study is an engineering analysis that identifies building components that can be depreciated over 5, 7, or 15 years instead of 27.5 years. This front-loads depreciation, creating much larger deductions in the early years of ownership.

How It Works

An engineer or specialized firm analyzes your property's construction costs and separates them into categories:

Example

Property cost basis: $400,000 (building only, land already separated)

Year 1 depreciation comparison (placed in service January, with bonus depreciation):

Year 1 deduction increases from $7,054 to $23,704 — an additional $16,650 in depreciation. At 24% tax rate, that's $3,996 in tax savings in year 1 alone. Over the first 5 years, the additional deductions can total $50,000–$80,000.

When Is a Cost Seg Study Worth It?

When It's NOT Worth It

Catch-up depreciation for existing properties

If you've been depreciating your property as all 27.5-year but could have used cost segregation from the start, you can do a "catch-up" adjustment. A cost seg study can reclassify components, and you deduct the missed accelerated depreciation in a single year (Section 481(a) adjustment). This can generate a massive one-time deduction. Consult a CPA specializing in real estate.

Bonus Depreciation: The Phase-Down Schedule

Bonus depreciation allows you to deduct a percentage of certain assets' cost in the first year, before normal depreciation begins. It applies to personal property (appliances, furniture) and land improvements — not to the building structure itself.

Bonus Depreciation Schedule

In 2026, you can take 20% bonus depreciation on eligible assets (those identified in a cost segregation study as 5, 7, or 15-year property). The remaining 80% is depreciated normally over the asset's recovery period.

While bonus depreciation is phasing down, it's still valuable. On $50,000 of eligible 5-year property in 2026: $10,000 bonus + $50,000 × 80% ÷ 5 = $8,000 normal = $18,000 total Year 1 depreciation instead of $10,000.

What Happens When You Sell: Depreciation Recapture

Depreciation isn't free money — it's a tax deferral. When you sell, the IRS "recaptures" the depreciation you claimed at a 25% flat rate.

How Recapture Works

Example: You sell a property after 10 years:

The gain is split into two parts:

Total tax on sale (at 15% capital gains rate): $18,910 + $12,000 = $30,910

Avoiding Recapture with a 1031 Exchange

A Section 1031 like-kind exchange defers both capital gains and depreciation recapture. You sell the property, identify a replacement property within 45 days, and close within 180 days. The deferred gain carries over to the new property's basis. You can repeat 1031 exchanges indefinitely, deferring taxes until you eventually sell for cash (or pass away, at which point heirs get a stepped-up basis).

Stepped-up basis: the ultimate tax strategy

If you hold a property until death, your heirs inherit it at a "stepped-up basis" — the fair market value at the date of death. All accumulated depreciation recapture and capital gains are eliminated. A property you bought for $250,000 that's worth $500,000 at death gives your heirs a $500,000 basis. They can sell immediately and pay $0 in capital gains and $0 in recapture. This is one of the most powerful tax benefits in real estate.

Common Depreciation Mistakes to Avoid

Depreciation and Passive Loss Rules

Depreciation creates paper losses that can offset rental income — but there are limits:

Building a Depreciation Schedule

For each property, maintain a depreciation schedule like this:

Also track separate schedules for:

Your CPA needs this schedule each year to prepare Schedule E and Form 4562. If you use property management software, this should be tracked automatically.

Depreciation is the closest thing to free money in the tax code. A non-cash deduction worth thousands per year, available to every landlord, regardless of income level. Don't leave it on the table — set up your depreciation schedule correctly from day one, consider cost segregation for larger properties, and plan for recapture when you sell. The tax savings are real, and they compound year after year.
