Difference between repairs and improvements in property rentals

The distinction between what constitutes a repair and what is considered an improvement is fundamental in determining the tax burden for property owners who obtain rental income. An erroneous classification can lead to an improper deduction or an undervaluation of the asset's acquisition cost.

What the DGT has ruled

The Dirección General de Tributos (DGT) has specified that repairs and maintenance are works intended to maintain the useful life and the capacity for use of the property. These expenses are directly deductible from the net income from real estate capital.

In contrast, improvements or expansions are interventions that increase the capacity, habitability, or useful life of the property. These concepts cannot be deducted as current expenses; instead, they must be integrated into the acquisition value of the property.

Furthermore, the ruling addresses expenses incurred before the property is rented. For these repairs to be deductible, they must be aimed exclusively at the future generation of income and not at the owner's personal enjoyment. The regulations establish that the deduction has a limit based on the gross income obtained, allowing the excess to be offset in the following four years.

What this means for you

If you are the owner of a home or premises intended for rent, you must classify every construction invoice with rigor. If the work only seeks to ensure the property remains functional, you may reduce your Personal Income Tax (IRPF) taxable base in the corresponding tax year. If the work provides added value that improves the conditions of the asset, the tax impact will shift to the time of the future sale, increasing the acquisition value.

What you should do

It is necessary to maintain detailed documentation that allows for the distinction of the nature of each intervention. In the case of works carried out before starting the leasing activity, it is vital to prove that their purpose is strictly the generation of income. Since the application of these criteria depends on the technical nature of the work, it is recommended to assess each situation individually.
