Everything You Need to Know About Depreciating Assets

If you own or manage rental property, you have probably heard the term "depreciating assets"—but what are depreciating assets, and how do they affect your taxes? Understanding depreciation is one of the most powerful ways to lower your taxable income and keep more of your rental profits. For deadlines and the full tax picture, see our 2026 Tax Prep Checklist; for the operational side of repairs vs improvements, see Who Fixes What?.

What Are Depreciating Assets?

Depreciating assets are tangible (and some intangible) property used in your business or for producing income that the IRS expects you to deduct over time rather than in a single year. For rental real estate, that typically means the building itself, plus items like appliances, flooring, and HVAC. The land is not depreciable.

Why Depreciation Matters for Property Managers

Depreciation lets you recover the cost of an asset over its "useful life." Instead of taking one big deduction when you buy a property, you spread the deduction across many years. For residential rental buildings, that useful life is 27.5 years. Properly tracking and claiming depreciation can significantly reduce your tax bill while staying compliant with the IRS.

Key Concepts: MACRS, Bonus Depreciation, and Safe Harbors

MACRS (Modified Accelerated Cost Recovery System)

MACRS is the IRS system for depreciating most business and rental property. Under MACRS, residential rental property (the building, not the land) is depreciated over 27.5 years using the straight-line method. Personal property used in rentals—such as appliances, carpeting, and certain improvements—may have shorter recovery periods (e.g., 5 or 7 years) and can sometimes qualify for accelerated or bonus depreciation.

100% Bonus Depreciation (OBBBA)

The One Big Beautiful Bill Act (OBBBA) permanently restored 100% bonus depreciation for qualifying property placed in service after January 19, 2025. That means you can deduct the full cost of eligible shorter-lived assets (e.g., new appliances, carpet, HVAC, qualified improvement property) in the first year instead of over 5 or 7 years. Qualified improvement property (QIP) generally means certain interior improvements to non-residential real property placed in service after the building; see the IRS tangible property regulations for details. This is a major opportunity for property managers making capital improvements.

De Minimis Safe Harbor

For smaller purchases, the IRS de minimis safe harbor lets you expense items that cost $2,500 or less per invoice (or $5,000 if you have an applicable financial statement) in the year you buy them—no depreciation schedule required. An applicable financial statement (AFS) is an audited financial statement or one filed with the SEC; most small landlords don't have one, so the $2,500 threshold applies. This simplifies recordkeeping for small tools, minor repairs, and similar items.

Residential Rental Property: The 27.5-Year Rule

The physical structure of your residential rental property is depreciated over 27.5 years. You must allocate the purchase price between land (non-depreciable) and building (depreciable). Your accountant or a qualified appraisal can help with the split. Depreciation begins when the property is placed in service (e.g., when it is ready for tenants).

Repairs vs. Improvements

Repairs maintain the property in its current condition and are generally deductible in the year incurred. Improvements add value or extend useful life and must be depreciated (or may qualify for bonus depreciation if they meet the rules). The IRS tangible property regulations provide detailed guidance on classifying costs. For deduct-now vs depreciate examples in plain language, see our Repairs vs Improvements for Taxes guide.

Practical Tips for Property Managers

• Keep detailed records of all improvements and their in-service dates.
• Track personal property (appliances, flooring, etc.) separately from the building when possible—they may qualify for faster depreciation or bonus depreciation.
• Use accounting or property management software to maintain depreciation schedules and support tax filing.
