Repairs vs. Improvements — and the Three Safe Harbors Most Landlords Miss

Landlord Ledger · Guides for landlords with 2–10 units · Published August 21, 2026 · Updated August 21, 2026

This is the tax question small landlords get wrong most often, in both directions. Deducting a $9,000 roof as a "repair" is the version that draws attention. Capitalizing a $400 water heater element because you were scared is the version that quietly costs you money every year.

The rules are more generous than their reputation. Here they are.

The default test: betterment, adaptation, restoration

Under the tangible property regulations you must capitalize an amount if it results in a betterment, an adaptation, or a restoration of the unit of property. Otherwise it is generally a currently deductible repair. (IRS: Tangible property final regulations.)

• Betterment — correcting a material condition or defect that existed before you acquired the property or arose during production; a material addition; or work reasonably expected to materially increase productivity, efficiency, strength, quality or output.
• Adaptation — adapting the property to a new or different use, inconsistent with your ordinary use of it.
• Restoration — replacing a major component or substantial structural part, returning the property to working order after it had deteriorated to unusable, or rebuilding to a like-new condition.

Safe harbor 1 — De minimis ($2,500 per invoice or item)

A taxpayer without an applicable financial statement may elect to expense amounts up to $2,500 per invoice, or per item as substantiated by the invoice. (The figure was raised from $500 by IRS Notice 2015-82; note that the regulation text itself still prints $500, which confuses everyone who reads the raw regulation.) With an applicable financial statement the limit is $5,000, which almost no small landlord has.

Three conditions matter:

1. You must have accounting procedures in place at the start of the tax year treating such amounts as expenses. They need not be in writing without an applicable financial statement — but writing a one-paragraph policy and dating it is close to free.
2. The election is annual, made by attaching a statement to a timely filed original return (including extensions). It cannot be made on an amended return.
3. The threshold applies per invoice or per item, so ten $900 items on one invoice can each qualify — provided the invoice substantiates them individually.

These amounts are not inflation-indexed and have not changed since 2016.

Safe harbor 2 — Small taxpayers

A qualifying taxpayer — average annual gross receipts of $10 million or less over the three preceding years — may elect, per building, to expense repairs, maintenance and improvements on a building with unadjusted basis of $1,000,000 or less, provided the total spent on that building for the year does not exceed the lesser of 2% of the building's unadjusted basis or $10,000.

Worked through: a duplex with an unadjusted basis of $300,000 has a limit of the lesser of $6,000 (2%) or $10,000 — so $6,000. Spend $5,400 on it that year and the whole lot can be expensed under the election. Spend $6,200 and you lose the safe harbor entirely for that building for that year — not just for the excess — and every item falls back to the ordinary betterment/adaptation/restoration analysis.

Important: the running total includes amounts you expensed under the de minimis and routine maintenance safe harbors as well — the limit is the aggregate spent on that building, not just the capitalizable part. That cliff edge is why the number is worth watching in December rather than discovering in April. Like the de minimis election, this is an annual election on a timely filed return.

Safe harbor 3 — Routine maintenance

Recurring work that keeps the property in its ordinarily efficient operating condition — inspection, cleaning, testing, replacing worn parts with comparable parts — can be treated as a deductible repair if, when the building structure or system was placed in service, you reasonably expected to perform the activity more than once during the following ten years.

No election or statement is required for this one; it is a method of accounting rather than an election. It does not apply to betterments, to restorations after a casualty loss, or to work on property that was in disrepair when you acquired it.

When it is genuinely an improvement

Capitalized work gets depreciated. The periods that matter for residential rentals:

"Placed in service" means ready and available for its intended use — for a rental, when the unit is ready and available to rent, not when a tenant moves in. (IRS Publication 527.)

One planning note worth raising with your preparer: bonus depreciation applies to property with a recovery period of 20 years or less, so the 27.5-year building itself never qualifies — but 5-year appliances and 15-year land improvements can. That makes the classification of a project into its components a conversation worth having with a professional rather than a spreadsheet.

The habit that makes all of this work

None of these rules can be applied retroactively to a shoebox. They require that you know, per building and per year, what you spent and on what. Flag improvements when you log them — see what to put in a maintenance log — keep a running total per building against the small-taxpayer limit, and hand your preparer a clean list in January.
