How the DGT's position has evolved
Current position
The 4% tax rate applies to the transfer of social housing under special regimes or public promotion. This rate also applies to housing with regional public protection, provided that its surface area, price, and income limits do not exceed the parameters of social housing. For any other case, the 10% rate applies.
The DGT's position remains constant in applying the 4% rate to social housing and regional housing that meets the state limits for surface area, price, and income. No changes are observed in the interpretation of the qualification requirements. The doctrine has remained stable throughout the entire sequence.
Turning points
