Construction of new home must be completed within four years to qualify for exemption

Applying the reinvestment exemption for the construction of a new primary residence requires strict compliance with timeframes that link the sale of the previous property with the start and completion of the new construction. An error in calculating these periods can lead to the loss of the tax benefit on the capital gain generated.

What the DGT has ruled

The Dirección General de Tributos (DGT) has specified that, for an individual to benefit from the Personal Income Tax (IRPF) exemption when reinvesting the proceeds from the sale of their primary residence into the construction of another, they must satisfy a double temporal condition:

• Reinvestment of the amount: The entire amount obtained from the transfer of the previous home must be applied to the construction of the new one within a maximum period of two years from the date of the sale.
• Completion of the work: The construction process must conclude within a period not exceeding four years from the start of the investment.

The regulations provide for very limited exceptions to this second deadline, allowing extensions only for exceptional causes or in situations involving the developer's insolvency.

What this means for you

If you are an individual who has sold your primary residence with the aim of building a new one and avoiding tax payments on the capital gain, it is not enough to allocate the money to the construction within the two years following the sale. It is imperative that the construction does not extend beyond four years from the start of the investment. Failure to meet this time limit for the completion of the work would invalidate the right to the exemption, forcing the taxpayer to pay tax on the gain obtained from the initial sale.

What you should do

It is necessary to maintain rigorous monitoring of the construction schedule and investment milestones. You must ensure that the cash flow from the sale is applied in its entirety to the construction within the two-year margin and that the construction project is designed to be completed before the fourth year from the start of the works passes. Each particular situation must be analyzed to verify that the deadlines comply with those established in the IRPF Law and its Regulations.
