A Must-Read Guide for Las Vegas Resident Landlords and Small Business Owners
I. Repairs
Definition: Minor fixes that keep an asset in normal operation, without extending its life or increasing its value.
Tax Treatment: Fully deductible in the year incurred.
Examples: Replacing a window glass in a rental property; fixing plumbing in a restaurant; repairing the floor in a retail store.
II. Improvements
Definition: Expenditures that extend the asset’s useful life, increase its value, or adapt it for a new use.
Tax Treatment: Cannot be deducted all at once; must be depreciated.
Examples: Replacing an entire air conditioning system in a rental; renovating a restaurant kitchen; remodeling a retail store.
III. Depreciation
Definition: The process of allocating the cost of an asset with a useful life greater than one year over its lifespan.
Common Lifespans: Residential rental property 27.5 years; commercial property 39 years; furniture/equipment 5–7 years; vehicles 5 years.
Accelerated Methods: Bonus Depreciation; Section 179 Deduction.
