How and why is the matching rule applied to the cost of a building?

The matching rule in accounting dictates that expenses should be recognized in the same period as the revenues they help generate. When it comes to the cost of a building, this means that the expense associated with the building is not fully recognized at the time of purchase; instead, it is capitalized and depreciated over its useful life. This approach aligns the building's cost with the income it produces over time, providing a more accurate representation of financial performance. By doing so, it ensures that financial statements reflect the ongoing utility of the asset in generating revenue.
