How the DGT's position has evolved
Current position
The reduction of net income under article 23.2 of the Law 35/2006 on Personal Income Tax (IRPF) requires that the lease be for residential purposes according to the LAU, which requires satisfying the tenant's permanent housing need. Seasonal rentals, university courses, or summer periods do not meet this requirement. Proving the effective use as a residence is a matter of fact that must be proven by the taxpayer.
The DGT's position has remained constant over time. Since 2014, the administration has reiterated that the reduction depends on the primary purpose of satisfying the permanent housing need, excluding seasonal or academic leases. The most recent rulings maintain this interpretation and emphasize the burden of proof on the taxpayer.
