Repair or improvement for rental property?

The rule in plain terms

Publication 527 states the default: an expense for repairing or maintaining your rental property may be deducted if you are not required to capitalize it. It then states the opposite rule in one sentence: you must capitalize any expense you pay to improve the property. The question for every invoice is whether it falls under improvement. This page answers both search questions at once, whether a repair is deductible and whether a given job is a repair or an improvement, because they are the same test.

The test has three prongs. If a job triggers any of them, it is an improvement. If it triggers none, it is a repair or maintenance cost and you deduct it as a rental expense when you pay it. Keep separate records of repairs and improvements, because the publication warns you will need the cost of improvements when you sell or depreciate.

Betterment

Betterments include fixing a pre-existing defect or condition, enlarging or expanding the property, and increasing its capacity, strength or quality. The common thread is that the property ends up better than it was before the job, not merely back to normal. Building a deck, adding a bathroom or a garage, installing central air where there was none, and putting in a sprinkler system all appear in Table 1-1 as improvements, and all are betterments in this sense.

Restoration

Restoration covers replacing a substantial structural part of the property, repairing damage after you properly adjusted the basis of the property for a casualty loss, and rebuilding the property to a like-new condition. A new roof appears on Table 1-1, as do a furnace, duct work and kitchen modernization.

Adaptation

Adaptation means altering the property to a use that is inconsistent with the intended ordinary use when you began renting it. For instance (our illustration, not the publication's), converting a garage into a separate apartment would change its use. If the change does not alter the use, adaptation is not the reason to capitalize.

Table 1-1: the publication's improvement list

Table 1-1 groups examples by area. Additions: bedroom, bathroom, deck, garage, porch, patio. Lawn and grounds: landscaping, driveway, walkway, fence, retaining wall, sprinkler system, swimming pool. Miscellaneous: storm windows and doors, new roof, central vacuum, wiring upgrades, satellite dish, security system. Heating and air conditioning: heating system, central air conditioning, furnace, duct work, central humidifier, filtration system. Plumbing: septic system, water heater, soft water system, filtration system. Interior improvements: built-in appliances, kitchen modernization, flooring, wall-to-wall carpeting, and insulation of the attic, walls, floor, pipes and ducts.

The table is a list of examples of improvements, not a ruling that every invoice with those words is capitalized. Use it to calibrate, then apply the three prongs.

Safe harbors and how to deduct

Two safe harbors can still let you deduct costs that look like improvements. If you elect the de minimis safe harbor for the tax year, you need not capitalize the de minimis costs of acquiring or producing certain real and tangible personal property, and you deduct them on Schedule E, line 19. And if your cost was for an improvement to a building or equipment, you may still deduct it under the routine maintenance safe harbor. The publication refers you to the IRS Tangible Property Regulations FAQ for the details, and so should you before relying on either.

A related wrinkle: if a tenant pays for a repair and takes it out of the rent, the repair cost is rental income to you and also a deductible rental expense. In the publication's furnace example, the tenant's repair bill is included in income and deducted.

What capitalizing means in dollars

Capitalized improvements are generally depreciated as if the improvement were separate property. Residential rental property uses straight line depreciation over 27.5 years. The publication's example: you pay $4,000 for a furnace installed May 1. Because it was placed in service in May, the Table 2-2d percentage is 2.273 percent, so first-year depreciation is $4,000 x 0.02273 = $91. A repair of the same $4,000 would have been fully deductible in the year paid, which is why the classification matters. Use the rental property depreciation calculator to see the stream of deductions, and see landlord insurance for another expense with a timing rule.
