What Is Depreciation on a Rental Property? A Simple Guide for New Investors
Depreciation is an annual tax deduction for the gradual "wearing out" of your rental property. For residential rentals, the IRS lets you deduct 1/27.5 of the building value each year — with no cash outlay. It's the single largest recurring deduction most rental investors have.
Depreciation is the tax code's recognition that physical assets wear out over time. A building's roof will eventually need replacement. Appliances wear out. Carpets get stained. Rather than waiting until those items actually fail, the IRS lets you deduct a portion of the property's value each year as a "depreciation" expense — even if you haven't spent a dollar on repairs.
How Rental Property Depreciation Is Calculated
The formula is simple: (Purchase Price − Land Value) ÷ 27.5 years = Annual Depreciation. Land cannot be depreciated because it doesn't wear out. You must allocate a portion of the purchase price to land (typically based on the assessed value ratio on your property tax bill) and depreciate only the building value.
| Property Value | Land Allocation (15%) | Depreciable Basis | Annual Deduction |
|---|---|---|---|
| $300,000 | $45,000 | $255,000 | $9,273/yr |
| $500,000 | $75,000 | $425,000 | $15,455/yr |
| $750,000 | $112,500 | $637,500 | $23,182/yr |
| $1,000,000 | $150,000 | $850,000 | $30,909/yr |
Why Depreciation Is So Powerful
Depreciation is a non-cash deduction. You don't write a check for it — it just reduces your taxable income on paper. For a rental property generating $30,000/year in net rental income, $15,000/year in depreciation reduces your taxable rental income by half. At a 32% tax rate, that's $4,800 in taxes you don't pay — every year, for 27.5 years.
For properties with enough depreciation to exceed rental income, the excess loss flows through to your tax return (subject to passive activity rules). This is where cost segregation becomes transformative — by accelerating depreciation into year one, a single year's deduction can exceed the property's annual rental income many times over.
Where Depreciation Goes on Your Tax Return
Rental income and expenses — including depreciation — are reported on Schedule E (Supplemental Income and Loss) attached to your Form 1040. Depreciation appears as a line item expense, reducing your net rental income (or increasing your rental loss). The depreciation is calculated on Form 4562 and flows to Schedule E.
Cost Segregation: Accelerating Depreciation
Standard straight-line depreciation over 27.5 years is just the default. Cost segregation reclassifies components of the property into shorter-life categories (5-year and 15-year) that depreciate faster — and with 100% bonus depreciation, qualify for full first-year deduction. The result: instead of $15,000/year for 27.5 years, you might take $130,000 in year one.
