Depreciation on Rental Property: The Ultimate Guide

What Is Rental Property Depreciation?

Depreciation is a non-cash tax deduction that allows you to recover the cost of a rental property over its useful life as determined by the IRS. For residential rental property, the recovery period is 27.5 years. For nonresidential (commercial) property, the recovery period is 39 years. The IRS requires you to use the Modified Accelerated Cost Recovery System (MACRS) and the mid-month convention, which means the property is treated as placed in service in the middle of the month you begin renting it.

The key to understanding depreciation is that it reduces your taxable income without requiring any cash outlay. If your rental property generates $20,000 in net operating income and your annual depreciation deduction is $12,000, you only owe tax on $8,000. Meanwhile, you received the full $20,000 in cash. This gap between taxable income and actual cash flow is the core reason real estate investing is so tax-advantaged.

How to Calculate Depreciation

Only the building (the structure and its components) is depreciable. Land is never depreciable. When you purchase a property, you must allocate the purchase price between land and building. The most common approach is to use the property tax assessment ratio. If the county assessor values the land at 20% and the improvements at 80%, you apply that same ratio to your purchase price.

For a property purchased at $400,000 with an 80/20 building-to-land split, the depreciable basis is $320,000. Add any closing costs that must be capitalized (title insurance, recording fees, transfer taxes, legal fees related to the purchase) to arrive at the total depreciable basis. If those costs add $8,000, the depreciable basis becomes $328,000.

The annual depreciation deduction for residential property is the depreciable basis divided by 27.5. In this example: $328,000 / 27.5 = $11,927 per year. The first and last years of the depreciation period are prorated using the mid-month convention. If you place the property in service in March, you depreciate 9.5 months of the first year.

Capital Improvements vs. Repairs

The distinction between repairs and capital improvements directly affects depreciation. Repairs restore the property to its existing condition and are fully deductible in the year incurred. Capital improvements add value, extend the property's useful life, or adapt it to a new use, and must be capitalized and depreciated separately.

Replacing a broken faucet is a repair. Replacing all the plumbing in a property is a capital improvement. Patching a section of roof is a repair. Installing an entirely new roof is a capital improvement that gets its own 27.5-year depreciation schedule.

The IRS provides safe harbors to simplify this distinction. The de minimis safe harbor allows you to expense items costing $2,500 or less per invoice (or $5,000 if you have an applicable financial statement). The routine maintenance safe harbor allows you to deduct the cost of maintenance activities you reasonably expect to perform more than once during the property's class life.

The Depreciation Recapture Trap

Depreciation is a deferral, not a permanent tax savings. When you sell the property, the IRS "recaptures" the depreciation you claimed (or should have claimed) by taxing that portion of your gain at a flat 25% rate under Section 1250. This recapture applies regardless of whether you actually deducted the depreciation. The IRS taxes the depreciation you were entitled to take, so there is no benefit to skipping the deduction.

For example, if you claimed $100,000 in depreciation over your holding period, you owe $25,000 in depreciation recapture tax at sale (in addition to any capital gains tax on the remaining appreciation). The only ways to avoid or defer recapture are through a 1031 exchange, holding the property until death (your heirs receive a stepped-up basis), or donating the property to charity.
