How the DGT's position has evolved
Current position
The acquisition value includes the cost of investments, improvements, and expenses inherent to the acquisition. Works that increase the capacity, habitability, or extend the useful life of the property are considered improvements or expansions. Repair and maintenance expenses intended to maintain the useful life or normal use of the asset do not form part of the acquisition value. The taxpayer must justify the nature of the works through objective means.
The DGT's position remains constant in the distinction between repair expenses and improvements. Throughout the rulings, it has been reiterated that works that increase capacity, habitability, or useful life increase the acquisition value, while maintenance works do not. The doctrine has been consistent from 2015 to 2026.
