Repairs vs. Capital Improvements: Why Property Owners Get This Wrong

Every dollar spent on a rental property falls into one of two tax categories, and which one it falls into changes when — and how much — you get to deduct it. A repair is deductible in full, the same year you pay for it. A capital improvement has to be capitalized and depreciated over its useful life, which for most residential rental property is 27.5 years.

The general rule under IRS regulations is that a repair keeps the property in its normal operating condition, while an improvement betters the property, restores it to like-new condition, or adapts it to a new use. Patching a section of roof after a storm is typically a repair. Replacing the entire roof is typically a capital improvement, even though both are, colloquially, "roof work."

This is where property owners consistently get it wrong in both directions. Some capitalize routine repairs unnecessarily, spreading a deduction over decades that they were entitled to take in full immediately. Others deduct a full-scale renovation in the year they paid for it, which can trigger an IRS notice — or simply understate the property's basis for years afterward, quietly costing money at sale.

There's a safe harbor that helps in the gray area: the de minimis safe harbor election lets you deduct amounts below a set per-item or per-invoice threshold outright, without having to make the repair-versus-improvement judgment call at all, as long as you have a consistent capitalization policy in place. Most owners have never elected it, simply because nobody told them it existed.

The fix isn't complicated once someone actually looks — it's reviewing what's been capitalized versus expensed against the actual nature of the work, correcting anything misclassified, and, where relevant, evaluating whether a cost segregation study would accelerate depreciation on components that qualify for a shorter recovery period. That's exactly the review we run for property management and real estate clients, because it's rarely done unless someone is specifically looking for it.
