What is the difference between repairs and capital improvements?
Repairs keep property in its ordinary operating condition. Capital improvements add value, extend useful life, or adapt property to a new use. The distinction matters because repairs are fully deductible in the year you pay for them, while capital improvements must be depreciated over multiple years.
The IRS uses three tests to determine if something is a capital improvement. First, betterment: does it fix a defect that existed when you acquired the property, or expand the property beyond its original state? Second, restoration: does it restore property that’s been damaged to like-new condition or rebuild a major component? Third, adaptation: does it adapt property to a new or different use? If the expense meets any of these tests, it’s likely a capital improvement.
Fixing a leak in your roof is a repair. Replacing the entire roof is a capital improvement. Patching drywall is a repair. Adding a bathroom or converting a garage to office space is an improvement. The scale and nature of the work both matter.
For HVAC systems, replacing a broken component is usually a repair. Installing an entirely new system is a capital improvement. The same logic applies to plumbing, electrical, and other building systems.
There’s a safe harbor that helps with smaller expenses. Businesses without audited financial statements can elect to deduct items costing $2,500 or less per invoice or item. This simplifies recordkeeping and lets you avoid capitalizing small purchases even if they might technically qualify as improvements.
Getting this wrong has real consequences. Deducting an improvement as a repair overstates your current deduction and understates depreciation. The IRS can disallow the deduction and assess penalties. Going the other way and capitalizing repairs ties up deductions you could have taken immediately.
Real estate investors deal with this constantly when turning over rental units. A fresh coat of paint, new carpet, and minor plumbing fixes after a tenant moves out are repairs. But if you gut the unit, replace all the appliances, and upgrade the electrical system, you’re looking at capital improvements that need to be depreciated.
Contractors should understand this distinction for their own buildings and equipment, not just for client projects. That new truck bed liner might be a repair. Adding a lift gate to the truck is an improvement.
When you’re unsure, document your reasoning. Take photos before and after. Keep invoices that describe the work in detail. If the IRS questions your classification years later, good documentation supports your position. Working with small business bookkeepers in New Mexico who understand these rules can help you categorize expenses correctly from the start and avoid problems down the road.
