How the DGT's position has evolved

Settled doctrine High confidence 95 rulings · 2015–2026

Current position

For the exemption due to reinvestment in housing construction, the total amount from the sale must be applied within a period of two years (before or after the transfer). Construction must be completed within a maximum period of four years from the start of the investment, except for extensions due to exceptional circumstances or the developer's insolvency. In the event of partial reinvestment, only the proportional part of the amount is excluded. It is permitted to include land costs in the construction of buildings.

The DGT's position remains stable regarding the temporal requirements for reinvestment (two years) and completion of works (four years). Since 2022, the doctrine has focused on the exemption for reinvestment following the suppression of the construction deduction, specifying the calculation of deadlines and the application of amounts in cases of partial reinvestment or the construction of buildings.

Turning points

  1. V2055-23

    Clarifies that the amount considered reinvested includes both the money obtained from the sale and the money obtained through a mortgage loan.

  2. V2633-24

    Establishes that in the construction of two buildings, the costs of the primary residence and the proportional part of the land may be included.
