How the DGT's position has evolved

Stable position High confidence 8 rulings · 2014–2023

Current position

The reduced rate of 10% applies to construction or rehabilitation works of buildings primarily intended for housing, which requires that at least 50% of the built-up area be allocated to said use. In the case of outdoor tanks, the occupied area counts at 20% and, if they have a structure or construction, at 55%. Unbuilt or uncovered area where the activity is not directly carried out, such as roads or parking lots, is not included in the calculation.

The DGT's position on the concept of a building primarily intended for housing remains constant, always requiring that residential use exceeds 50% of the area. The most recent rulings introduce specific criteria for calculating areas in specific activities, such as tanks or declared variations in area.

Turning points
