Construction of a new home must be completed within four years to apply the exemption

Individuals wishing to avoid paying Personal Income Tax (IRPF) by reinvesting the capital gain obtained from the sale of their primary residence must observe very specific deadlines when the funds are intended for the construction of a new property.

What the DGT has ruled

The Directorate General of Taxes (DGT) has specified the requirements necessary to apply the exemption in the case of home construction. For the operation to be valid, two concurrent conditions must be met:

• Reinvestment period: The amount obtained from the sale of the previous home must be reinvested within a period of two years, either before or after the transfer.
• Construction completion period: The construction of the new home must be completed within a maximum period of four years from the start of the investment.

The tax authority clarifies that the calculation of the construction period begins from the first payment made for the work that is considered as the reinvested amount. However, this four-year period allows for an extension if exceptional circumstances not attributable to the taxpayer occur or if the developer enters insolvency proceedings.

What this means for you

If you have sold your primary residence and plan to use that capital to build a new home, making the initial payments is not enough. The regulations require that the work be completed within the established time limit. If construction extends beyond four years without justified force majeure causes or developer insolvency situations, you will lose the right to the exemption on the capital gain, which will result in an unexpected tax cost.

What you should do

It is essential to rigorously monitor construction schedules and payments made. Since the construction period is calculated from the first disbursement intended for the investment, it is necessary to document every payment to determine exactly when the calculation begins. In the event of any construction delay exceeding four years, it is necessary to evaluate whether exceptional circumstances exist that allow for a request to extend the period to avoid losing the tax benefit.
