Main residence deduction: impact of loan restructuring

Managing the financing of your main residence involves decisions that can directly affect taxpayers' tax burden. Recently, the Directorate General of Taxes (DGT) has issued a relevant ruling regarding the continuity of the deduction for investment in the main residence in debt restructuring scenarios.

What the DGT has ruled

The query concerned whether the cancellation of a mortgage loan and the simultaneous contracting of a new one allowed for the maintenance of the right to a deduction for the amounts amortized. The DGT has determined that the novation, subrogation, or substitution of a loan does not exhaust the possibility of applying the deduction, provided that the new loan is used to amortize the previous one.

The ruling establishes that if the cancellation and the signing of the new contract are carried out in the same simultaneous act, the annual installments, interest, and cancellation or establishment costs will be deductible in the proportional part attributable to the investment in the residence. However, the administration warns that if a cancellation occurs and, subsequently, a new loan is contracted without a direct connection, the right to the deduction for the new financing would be lost.

What this means for you

This ruling directly affects natural persons who hold the right to the deduction for investment in the main residence under the transitional regime and who wish to modify their financing conditions. The key lies in the timing and the purpose of the operation:

• Simultaneity: If the substitution operation is immediate and the new credit is intended to amortize the previous one, the deduction is maintained.
• Associated costs: Costs derived from the operation (cancellation or establishment) can also be proportionally deductible.
• Risk of loss: A break in temporal continuity between the cancellation and the new contracting can lead to the loss of the tax benefit for the new debt.

What you should do

In the event of a possible restructuring of mortgage debt, it is necessary to analyze the structure of the financial operation. The direct connection between the cancellation of the old loan and obtaining the new one is the determining factor for preserving the right to the deduction according to Law 35/2006 on Personal Income Tax (IRPF). It is recommended to assess each particular case to ensure that the financial operation does not interrupt the tax right.
