How the DGT's position has evolved
Current position
Repair and maintenance expenses are deductible for Personal Income Tax (IRPF) if the property is used for economic activity and its portion is capable of independent use. They are distinguished from improvements, which increase the acquisition value and are deducted through depreciation. Regarding Value Added Tax (IVA), the deductibility of works depends on whether they are considered investment goods and the percentage of use for the activity.
The DGT's position remains constant regarding the technical distinction between repairs and improvements. Rulings confirm that repairs are expenses for the current fiscal year, whereas improvements increase the acquisition value. The doctrine has focused on specifying the partial use of the dwelling and the nature of the works to determine their tax treatment.
Turning points
-
Establishes that in the case of partial use, only those parts capable of separate and independent use are considered used for the activity.
-
Clarifies that repair works do not form part of the acquisition value, whereas improvements that increase capacity or useful life do.
