How the DGT's position has evolved
Current position
The exemption requires reinvesting the total amount obtained in the acquisition or rehabilitation of a new primary residence within a period of two years (before or after the sale). The amount obtained is calculated by subtracting the principal of the outstanding loan from the transfer value. If the reinvestment is partial, only the proportional part of the gain corresponding to the amount actually invested shall be excluded.
The DGT's position remains constant regarding the definition of the requirements for the reinvestment exemption. Clarifications have been integrated concerning the calculation of the amount obtained, specifically the deduction of the outstanding principal and the application of proportionality in the event of partial reinvestment. There are no substantive changes to the timeframe or the nature of the housing.
Turning points
-
Specifies that the amount obtained for the calculation of the exemption is the transfer value minus the outstanding loan amounts.
-
Formally defines the transfer value as the sale price minus expenses and inherent taxes paid by the seller.
