How the DGT's position has evolved
Current position
The exemption requires that both the transferred and the acquired property be primary residences. The reinvested amount comprises the price and acquisition costs of the new home, including both own funds and external financing. It is not mandatory that the funds used be the same ones obtained from the sale, given the fungibility of money. The acquisition must take place within a period of two years before or after the transfer.
The DGT's position has moved from a restrictive criterion in 2014, where only the amount used to reduce debt was considered reinvested if the property was already fully paid, to a consolidated criterion of fungibility. Rulings from 2022 onwards confirm that the reinvested amount is the total acquisition value, regardless of the source of financing.
