The regulations set forth the general rule that amounts paid to improve a property unit must be capitalized. An improvement is defined as an expenditure that betters a unit of property, restores it, or adapts it to a new and different use. The treasury regulations include various examples and explanations of betterment, restoration, and adaption tests.
Betterments look at whether the property is in a materially better condition above and beyond what the asset needed in repair after the incurred expenditure. Additions, expansions, and physical enlargements to the Unit of Property (defined below) must be capitalized. Strengthening, increasing productivity, and efficiency, or the quality of the asset also reflect a betterment.
Restorations generally look at whether the taxpayer is replacing a major property component or substantial structural part that may perform a discrete and critical function to the asset’s intended use. If an asset is in a state of disrepair and is brought back to life for its intended use, the costs will generally be capitalized and depreciated.
Adaptation is the simplest standard to understand and measure. The taxpayer solely looks at whether the asset is being used for a new or different use than its originally intended use.
If you fail to meet all three capitalization standards above, your costs are considered repair and maintenance expenses, regardless of the dollar amount. So, what previously you may have capitalized as a $50,000 improvement for fixing part of a roof or plumbing issue may be written off in the current year.
