DEDUCTIONS AND REDUCTIONS APPLICABLE TO PERSONAL INCOME TAX ON INCOME FROM RENTING OUT A RESIDENTIAL PROPERTY
DEDUCTIONS AND REDUCTIONS APPLICABLE TO PERSONAL INCOME TAX ON INCOME FROM RENTING OUT A RESIDENTIAL PROPERTY
When a property is let, the owner or, alternatively, the usufructuary must declare the total income received in their income tax return. The regulations allow for a number of expenses to be deducted, as detailed below:
1. Interest and other financing costs for borrowed capital invested in the acquisition or improvement of the asset, right or entitlement to use or enjoyment.
This includes loan interest, origination or processing fees, and other expenses related to financing or cancellation.
The maximum total amount deductible for interest and other financing costs (together with the maintenance and repair expenses mentioned in the following section) may not exceed, for each asset or right, the amount of the gross income obtained. Any excess may be deducted in the following four years.
2. Maintenance and repair expenses.
These are expenses incurred to maintain the normal use of real estate, such as painting, plastering or repairing installations, and the replacement of elements, such as heating systems, elevators, security doors or others.
Amounts allocated to the expansion or improvement of the property are not deductible under this heading, as they constitute an increase in the acquisition value, the recovery of which is effected through the corresponding depreciation charges.
3. Taxes, surcharges and fees.
This includes taxes and surcharges that are not levied by the central government, as well as state-level fees and surcharges. For example: property tax (IBI), garbage collection fees, etc.
4. Amounts accrued by third parties as a result of personal services.
For example: administration, security, concierge, garden maintenance, etc.
5. Lease formalization and legal defense expenses.
This includes fees paid to professionals for drafting and formalizing the lease agreement and attorney and legal representative fees in the event of disputes with the tenant (non-payment of rent, breach of contract, etc.).
6. Doubtful debts.
These will be deductible when the risk of non-collection is duly justified. To qualify, at least one of the following requirements must be met:
- The debtor is subject to insolvency proceedings.
- More than six months must have elapsed between the taxpayer's first collection attempt and the end of the tax period, and the debt must not have been renewed.
When a doubtful debt is collected after its deduction, this income must be declared in the tax year in which the collection takes place.
7. Insurance premiums.
These can refer to home insurance, liability insurance or rent guarantee insurance, provided they cover the assets or rights that generate the income.
8. Services or utilities.
Amounts spent on services or utilities, such as water, electricity, gas, internet, etc., are deductible if they have been incurred and paid for by the landlord.
9. Other necessary tax-deductible expenses.
In addition to the expenses specifically listed above, any other expense is considered tax-deductible provided that it is necessary for the generation of the corresponding income.
10. Amounts allocated to depreciation.
Depreciation reflects the loss of value of real estate and other assets transferred with it due to use or the passage of time.
In the case of real estate, annual depreciation may not exceed 3% of the higher of the acquisition cost (excluding the land) and the cadastral value of the building. For fixtures, fittings and equipment, the limit is 10% per year.
Regarding the expenses listed, they will only be deductible for the period during which the property was rented and generating income, in proportion to the corresponding income-expense matching principle. However, maintenance and repair expenses will be deductible even if they were incurred while the property was not rented, provided they were carried out for the purpose of renting the property and not for the owner's personal use.
Furthermore, if the property was only partially rented, only the expenses proportional to the rented portion will be deductible.
A reduction may be applied to the net income remaining after deducting the aforementioned expenses. This reduction will vary depending on which of the following requirements are met:
• A 90% reduction when the same landlord has entered into a new lease agreement for a property located in a high-demand residential market area, where the initial rent has been reduced by more than 5% compared to the last rent of the previous lease agreement for the same property, after applying, where applicable, the annual adjustment clause of the previous contract.
• A 70% reduction when any of the following circumstances take place:
- The taxpayer is renting the property for the first time, provided it is located in a high-demand residential area and the tenant is between 18 and 35 years old.
- The tenant is a public administration or non-profit entity that uses the property for social housing.
• A 60% reduction when the property has undergone renovation work, provided that the work was completed within the two years prior to the date the lease agreement was signed.
• A 50% reduction in all other cases.
