How the DGT's position has evolved

Settled doctrine High confidence 8 rulings · 2014–2025

Current position

The deductibility of expenses and interest requires that the liability be necessary to obtain income and that the asset be used for the activity. Capital gains or losses from the transfer of business assets are determined by the difference between the transfer value and the book value. In the case of real estate, depreciation is calculated on the acquisition value excluding the land, and may include notary, registry, or loan origination expenses.

The position of the DGT remains stable in determining capital gains or losses through the book value for business assets. There is a constant reiteration in the requirement of a link and the necessity of the expense for its deductibility. No doctrinal changes are observed, but rather a uniform application of the criteria for business use and book value assessment.
