INTRODUCTORY DISCUSSION OF THE BASIC
CONCEPTS OF DEPRECIATION AND EXPENSING
Depreciation, the deduction of the cost of physical capital over time, is employed in the tax code
to determine allowable business deductions for the cost of investment. Depreciation is a flawed
concept that understates the real cost of plant, equipment, and structures, overstates business income,
boosts business taxes, and greatly increases the cost to businesses of acquiring and employing
capital. The result is less investment and capital formation than would occur under a more rational
treatment of capital expenditures. Expensing, the immediate deduction of the cost of acquiring
plant, equipment, structures, and inventory, is the economically correct way to treat investment for
tax purposes. This paper is intended to provide the reader with a clear understanding of the concepts
of depreciation and expensing, and to show that the proper treatment of capital expenditures can
significantly increase the nation's prosperity. It should be noted that all of the major consumption-
based tax reform proposals have, at their core, an explicit or implicit shift from depreciation to
expensing of investment outlays.
Depreciation is aflawed concept that understates the real cost ofplant, equipment,
and structures, overstates business income, boosts business taxes, and greatly
increases the cost to businesses of acquiring and employing capital.
What are depreciation and expensing all about?
To determine profit, businesses must subtract their costs from their revenues. Costs include,
among other things, labor, raw materials, inventory, and the cost of plant, equipment, and structures.
Expensing is the immediate subtraction of the cost of plant, equipment, structures, and inventory
from revenue at the time the asset is purchased. Expensing is used in cash flow accounting, the
simplest and most common-sense kind of record keeping.
