What Are Capital Expenses for Rental Property: Depreciation Rules

Capital expenses for a rental property are costs that improve, restore, or adapt the property rather than simply keep it running, and the IRS requires you to spread those costs across multiple years through depreciation instead of deducting them in the year you pay. The building itself depreciates over 27.5 years; appliances, carpeting, and landscaping run on faster schedules.¹ Classifying an expense correctly controls when you get the deduction, how much you owe when you sell, and whether your return holds up under scrutiny.

Capital Improvement or Repair

A repair keeps the property in its current working condition. Patching a roof leak, fixing a broken toilet, repainting a room — those come off your income in the year you pay them. A capital improvement, by contrast, makes the property better, brings it back from serious deterioration, or changes its use. Treasury Regulation 1.263(a)-3 lays this out in a three-part test the IRS calls BAR: Betterment, Adaptation, and Restoration.¹

Betterment. You fix a defect that existed before you bought the property, expand a structure, or upgrade a system to meaningfully higher capacity or quality than what was there.
Adaptation. You convert the property to a new use, such as turning a residential rental into commercial retail space.
Restoration. You replace a major component or substantial structural part, rebuild the property to like-new condition, or repair damage from a casualty loss for which you adjusted your basis.

Trigger any one of the three and the cost gets capitalized. The IRS applies each test at the level of the “unit of property,” meaning the whole building system rather than the piece you touched. Replacing one faucet washer is a repair. Replacing the plumbing throughout the building is a restoration.

Common Capital Expenses on a Rental

Publication 527 walks through the items the IRS treats as improvements. They sort into a handful of familiar categories.¹

Structural work: a new roof, replacement flooring throughout a unit, permanent wall coverings.
Heating and cooling: a new furnace, heating system, or central air conditioning.
Plumbing and electrical: rewiring, replacing the plumbing, a new water heater, a new septic system.
Appliances and furnishings: stoves, refrigerators, wall-to-wall carpeting, furniture used in the rental unit.
Land improvements: fences, sidewalks, driveways, landscaping, drainage, parking areas.
Additions and upgrades: new storm windows, security systems, and similar installations.

The question is not how much you spent. It is whether the work bettered the property, restored it from serious decline, or adapted it to a new use.

How Long Each Type Takes to Depreciate

Once an expense is capital, the recovery period depends on what you improved. Classifying each item correctly determines how quickly you get your money back through deductions.

The Building and Its Structural Components — 27.5 Years

Residential rental buildings and their structural components depreciate over 27.5 years on a straight-line basis.¹ Furnaces, water pipes, venting, a new roof, a full HVAC replacement — all part of the building for depreciation purposes. The clock starts the month the improvement is placed in service, and the first month counts as a half-month regardless of the actual date.

Land Improvements — 15 Years

Work done to the land itself — fences, roads, sidewalks, landscaping, drainage — falls into a 15-year recovery class.² A new parking lot or retaining wall runs on this schedule rather than the building’s.

Appliances, Carpeting, and Furniture — 5 Years

Personal property inside the unit runs on a much shorter clock. Stoves, refrigerators, wall-to-wall carpeting, and rental-unit furniture are 5-year property under the general depreciation system.¹ You recover the cost in roughly a fifth of the time a structural improvement takes.

Safe Harbors That Let You Deduct Anyway

Several IRS elections let you expense costs immediately even when they would otherwise be capital. They matter most for smaller landlords and smaller purchases.

De Minimis Safe Harbor

Without an applicable financial statement (most individual landlords do not have one), you can immediately deduct any item of tangible property costing $2,500 or less per invoice.³ You need a consistent accounting procedure in place at the start of the tax year and you make the election each year on your return. Taxpayers with an applicable financial statement use a $5,000 threshold.

Safe Harbor for Small Taxpayers

This one applies to buildings with an unadjusted basis of $1 million or less. If your total spending on repairs, maintenance, and improvements for the building during the year does not exceed the lesser of $10,000 or two percent of that unadjusted basis, you can deduct all of it instead of capitalizing the improvements.⁴ You also need average annual gross receipts of $10 million or less. Every maintenance and improvement dollar spent on the building counts toward the limit, so one large project can push you over and disqualify the election for the whole year.

Routine Maintenance Safe Harbor

Even work that looks like a restoration can be deducted if it qualifies as routine maintenance. The activity has to be recurring — something you reasonably expect to do more than once during the first ten years after the building or system is placed in service — and it has to keep the property in ordinary operating condition.⁴ Servicing HVAC on a schedule fits. Betterments do not, so upgrades that push capacity or quality past the original state are out.

Faster Write-Offs When You Do Have To Capitalize

The 27.5-year building schedule is fixed, but shorter-lived assets around and inside the property may qualify for accelerated recovery, sometimes down to a single year.

Bonus Depreciation

Under the One, Big, Beautiful Bill enacted in 2025, qualified property acquired after January 19, 2025, gets a permanent 100-percent first-year depreciation deduction.⁵ Bonus depreciation only applies to property with a MACRS recovery period of 20 years or less.⁶ For a rental owner that covers 5-year assets (appliances, carpet, furniture), 7-year assets (certain office furniture), and 15-year land improvements (fences, parking lots, sidewalks). The 27.5-year building structure is not eligible.

Section 179 Expensing

Section 179 lets you write off the full cost of qualifying property in the year it is placed in service, up to an annual limit. For 2026 the maximum is roughly $2.5 million, with the deduction phasing out once total qualifying property placed in service exceeds around $4 million. Like bonus depreciation, Section 179 covers personal property such as appliances, carpeting, and furniture used in your units, not the residential rental building or its structural components.¹ You claim it on Form 4562, and the amount expensed reduces the property’s depreciable basis going forward.

Cost Segregation Studies

A cost segregation study is an engineering analysis that breaks a building’s components into separately classifiable assets. Without one, the entire purchase price of the rental (minus land) typically defaults to the 27.5-year schedule. A study might reclassify decorative lighting, cabinetry, countertops, and dedicated electrical outlets as 5-year personal property, and parking lots, landscaping, and drainage as 15-year land improvements. Once reclassified, those components can also qualify for bonus depreciation.

Study fees vary. Technology-driven providers may charge under $2,000; traditional engineering-based firms typically run $5,000 to $10,000 or more depending on the property. The math tends to work only when projected tax savings comfortably exceed the fee, which usually points to higher-priced properties.

When You Replace a Component: The Partial Disposition Election

Replacing a major component creates a quiet problem. Tear off an old roof and install a new one, and you have to capitalize the new roof as a separate improvement. Meanwhile the undepreciated cost of the old roof is still sitting on your depreciation schedule, quietly running out over the remainder of its 27.5 years even though the roof is in a dumpster.

Treasury Regulation 1.168(i)-8(d)(2) lets you elect a partial disposition. You claim a loss for the remaining adjusted basis of the old component in the year it comes out, effectively writing off the depreciation you had not yet taken.⁷ There is no separate form. You make the election by reporting the loss on a timely filed return for the year of disposition. Skip it and you end up depreciating both the old and new components at the same time, inflating your basis and setting up complications at sale.

What Happens When You Sell: Depreciation Recapture

Every dollar of depreciation reduces your income now and creates a tax obligation later. When you sell, the IRS recaptures the benefit by taxing the depreciation-related portion of your gain.

For residential rental property this is “unrecaptured Section 1250 gain.” The portion of gain attributable to depreciation you previously claimed is taxed at a maximum federal rate of 25 percent, higher than the long-term capital gains rate that applies to the rest of the profit.⁸ Gain beyond total depreciation taken is taxed at your regular capital gains rate.

Here is the trap. The IRS calculates recapture on depreciation “allowed or allowable,” whichever is greater.² If you were entitled to $50,000 of depreciation over the years and never claimed a dollar of it, the IRS still treats your basis as though you did. You owe the recapture tax on deductions you never actually received. Claiming every depreciation deduction you are entitled to is not optional in any practical sense.

Fixing Missed Depreciation

If you never depreciated a rental you should have, you do not go back and amend each old return. You file Form 3115, Application for Change in Accounting Method, to switch from an impermissible method (not depreciating property you were required to depreciate) to the correct one.⁹

The form triggers a Section 481(a) adjustment covering the cumulative depreciation you should have taken in prior years. Because missed depreciation is a negative adjustment (it reduces taxable income), you generally claim the full cumulative amount in a single year: the year of the change.⁹ It falls under the automatic change procedures, so no IRS user fee applies and consent is granted automatically when you meet the filing requirements. Given the “allowed or allowable” rule, filing this correction is not just about recovering deductions. It keeps you from paying recapture tax on depreciation you never used.
