How the DGT's position has evolved

Settled doctrine High confidence 66 rulings · 2014–2026

Current position

Renovation and repair works in buildings intended for housing may be taxed at the reduced rate of 10% if the recipient is a natural person or a community of owners and the construction was completed more than two years ago. It is an essential requirement that the cost of the materials provided does not exceed 40% of the taxable base of the transaction. If this limit is exceeded, the general rate of 21% will apply to the entire execution of the works.

The DGT's position has remained constant since 2015. Following an initial phase in 2014 with reconstruction requirements, the doctrine was established in 2015 by setting the 40% limit for the cost of materials. Since then, all rulings confirm this threshold and the consequence of applying the general rate to the total transaction if it is exceeded.
