Repairs versus improvements, and why the line matters

Money spent on a rental property is either currently deductible as a repair or capitalized and depreciated as an improvement.

The difference in timing is substantial. A $9,000 expenditure deducted this year reduces taxable income by $9,000 now. Capitalized over 27.5 years, it reduces taxable income by about $327 a year.

The general distinction

A repair keeps the property in ordinary efficient operating condition. An improvement betters it, restores it, or adapts it to a new use.

The Internal Revenue Service regulations articulate this through three categories, generally referred to as betterment, restoration and adaptation.

Betterment — fixes a material defect that existed before acquisition, materially adds to the property, or materially increases capacity, productivity, efficiency, strength or quality.

Restoration — replaces a major component or substantial structural part, returns the property to operating condition after it had deteriorated to a state of disrepair, or rebuilds to like-new condition.

Adaptation — changes the property to a new or different use.

The unit of property concept

The technical point that determines many outcomes.

Whether something is a repair or a replacement of a major component depends on what the relevant unit of property is.

For buildings, the regulations identify the building structure and several separately defined building systems — including HVAC, plumbing, electrical, fire protection, escalators, elevators, gas distribution and security systems.

Each is analyzed separately. Replacing one of three rooftop HVAC units is analyzed against the HVAC system as a whole, which is why it may be a repair, whereas replacing the entire system is a restoration.

The safe harbors

The regulations provide several elections that simplify matters considerably, and they are underused.

De minimis safe harbor. Allows expensing of items below a per-item or per-invoice threshold, provided the taxpayer has a written accounting policy in place at the start of the year and follows it.

The threshold differs depending on whether the taxpayer has an applicable financial statement. For most small investors, a written capitalization policy adopted before the year begins is the requirement, and many do not have one.

Safe harbor for small taxpayers. Permits certain taxpayers with buildings below a specified unadjusted basis to expense repairs, maintenance and improvements up to a limit based on a percentage of unadjusted basis or a dollar figure, whichever is less.

Routine maintenance safe harbor. Allows expensing of activities reasonably expected to be performed more than once during a defined period — ten years for buildings — to keep the property in ordinary operating condition.

The specific thresholds and conditions change and should be confirmed with a tax professional for the current year.

Typical classifications

Generally treated as repairs: patching a roof section, fixing a leak, replacing broken windows, repainting, servicing HVAC, replacing a faucet, minor drywall repair, replacing a few damaged floorboards.

Generally treated as improvements: full roof replacement, new HVAC system, rewiring, replumbing, new windows throughout, room additions, kitchen and bathroom remodels, converting a space to a different use.

The ambiguous middle is where professional advice earns its cost, and where documentation at the time makes the difference.

The renovation-before-rental trap

Worth knowing because it catches new investors.

Work performed to prepare a property for its first rental use is generally capitalized rather than expensed, because it relates to placing the property in service rather than maintaining it.

An investor who buys a property, spends $40,000 renovating it, and then rents it, generally cannot deduct that $40,000 as repairs. It is added to basis and depreciated.

The classification of work performed after the property is in service is a different analysis.

Partial disposition

An underused provision.

When a component is replaced — a roof, for instance — an election is available to recognize the disposition of the old component, writing off its remaining undepreciated basis.

Without it, you continue depreciating a roof that no longer exists while also depreciating its replacement.

This requires knowing the original component's allocated basis, which requires either a cost segregation study or a reasonable estimation method.

What to actually do

Adopt a written capitalization policy before the tax year begins, so the de minimis safe harbor is available.

Describe work specifically on invoices. "Repaired leak at north valley and replaced twelve damaged shingles" supports a repair classification. "Roof work" does not.

Photograph before and after.

Do not aggregate. A single invoice covering a full renovation is harder to classify than separate invoices for distinct work.

And engage a tax professional who works with rental property, because this area is genuinely technical, the amounts are meaningful, and the rules have specific elections that must be made timely.
