How to calculate the net return on real estate capital
To understand how to reduce taxes on renting an apartment, you first need to understand the tax mechanics. Income generated from a lease is taxed in the personal income tax (IRPF) as real estate capital income.
Therefore, the base on which you will pay taxes is not the total gross income. The calculation is performed on the net earnings, which is the result of subtracting deductible expenses from the received income.
The more expenses you can correctly justify, the lower your net earnings will be. As a result, the final IRPF amount you will have to pay to the Tax Agency will be reduced considerably.
The importance of the prorating rule
A very common mistake occurs when the property has not been rented for the entire year. In this case, the Tax Agency requires the proration rule to be applied strictly.
This means that you will only be able to deduct expenses proportional to the actual time of the contract. For example, if you rented your apartment in Mallorca for six months, you will only be able to deduct half of the annual IBI bill.
At Gestoría G1 we always recommend keeping a thorough record of tenants' move‑in and move‑out dates. This will prevent possible penalties during a tax audit for improper deductions.
Main deductible expenses in the rental of a property
Knowing exactly which expenses can be deducted from rent makes a difference in your profitability. Below, we break down the most important items that tax regulations recognize for landlords.
Mortgage and loan interest
If you financed the purchase of the property with a mortgage loan, the interest paid annually is deductible. The same applies if you took out a loan to carry out conservation work on the home.
However, you must be very careful: only the interest is deductible, never the amortized principal. The portion of your monthly payment that goes toward repaying the loan principal does not count as an expense.
Furthermore, there is a legal limit. The sum of financial expenses and repair expenses cannot exceed the gross rental income for that year. The excess can be carried forward and offset in the next four fiscal years.
Municipal taxes and fees
Taxes that are levied directly on the property are a clear example of deductible expenses in property leasing. The most well-known is the Property Tax (IBI).
You can also include the municipal waste collection fee, provided the bill is in your name and you pay it yourself. Any other local tax linked to the dwelling receives the same tax treatment.
Condominium fees and special assessments
If your apartment or premises belongs to a community, the regular monthly fees are fully deductible. This is a fixed expense that directly reduces your taxable base month by month.
Likewise, extraordinary special assessments can also be included, provided they are allocated to the building's maintenance. Many owners forget this concept, losing a valuable deduction on their personal income tax.
Insurance premiums linked to the home
The annual cost of home or multi-risk insurance is an expense you can deduct from your income. If the policy includes civil liability coverage, the full premium is deductible.
Similarly, rent default insurance, which is increasingly popular in Mallorca, is fully tax-deductible. Always keep the bank receipt and the policy as proof for the tax authorities.
Legal expenses and contract formalization
If you hire a professional to draft the lease agreement, their fees are deductible. This includes services from real estate agencies, management firms, or specialized lawyers.
Moreover, if you have a conflict with the tenant and need legal defence, those costs are also tax-deductible. The expenses of an eviction lawsuit or the claim for unpaid rents reduce your net income.
Repairs versus improvements: which expenses can be deducted in rental
This is one of the areas that generates the most doubts among our clients. To correctly apply tax deductions as a residential landlord, you must distinguish between maintaining and improving.
Concept of deductible repair and maintenance
Repairs are those necessary interventions to keep the property in optimal habitability conditions. These expenses are fully deductible in the year they occur.
For example, fixing a broken pipe, repairing the existing boiler, or painting the walls after normal wear and tear. The key is that the action addresses a maintenance need, not an aesthetic whim.
Investments and improvements not directly deductible
On the contrary, improvements are works that increase the value, capacity, or useful life of the property. These cannot be deducted as a direct expense in the current fiscal year.
Installing air conditioning where there was none or completely renovating a kitchen in good condition are improvements. Their cost is recovered gradually through depreciation over several years.
| Type of intervention | Practical example | Tax treatment |
|---|---|---|
| Repair / Maintenance | Fix leaks or replace a broken glass | Direct deductible expense in the current year |
| Improvement / Investment | Close a terrace to expand the living room | It is amortized annually (not a direct expense) |
At Gestoría G1 we carefully analyze our clients' invoices in Mallorca. This ensures that each invoice is correctly classified, avoiding parallels and surcharges from the Tax Agency.
Property depreciation: the key tax deduction for residential landlords
Depreciation is the star expense for any property owner. It allows you to deduct the theoretical loss of value that the property suffers over time, without requiring an actual cash outlay.
Calculation of construction depreciation
The regulations allow an annual deduction of 3% of the construction value. To calculate it, you must take the greater of two values: the acquisition cost or the cadastral value of the property.
It is vital to remember that the value of land never depreciates, as land does not lose value over time. You should only apply the percentage to the portion corresponding to the building.
Depreciation of furniture and appliances
If you rent out your furnished apartment, you can also depreciate the wear and tear of the furnishings. The usual rate for furniture and appliances is 10% per year, as their useful life is shorter.
To benefit from this deduction, you must keep the purchase invoices. Additionally, it is highly recommended to include a detailed inventory in the rental contract signed by the tenant.
Other lesser-known deductible expenses
Beyond the usual expenses, there are other specific situations that can generate deductions. Knowing them will help you understand how to comprehensively reduce rental taxes on an apartment.
Utilities borne by the landlord
Generally, the tenant pays for electricity, water, and gas. However, if the contracts are in your name and you assume the cost by including it in the rent, those bills are deductible.
This is very common in room rentals or seasonal leases. If you pay the bill to the supplying company, that amount will be deducted from your gross income.
Doubtful receivables due to tenant non-payment
Suffering a missed payment is a complex situation. The tax authority forces you to declare the accrued income even if you haven't received it, which is very frustrating for the owner.
Fortunately, you can deduct that missed payment as a doubtful collection balance if you meet certain requirements. The main one is that more than six months have passed since the first verifiable claim until the end of the year.
Common mistakes when applying tax deductions as a housing landlord
The complexity of tax regulations causes many owners to make mistakes in their filing. These errors can trigger inspections and unnecessary financial penalties.
Including personal expenses or amortized capital
A classic mistake is trying to deduct personal travel expenses to visit the property. The Tax Agency is very strict and usually rejects these items if they are not perfectly justified.
Another serious mistake is to deduct the full mortgage payment instead of only the interest. At Gestoría G1 we meticulously review each draft to ensure that only the correct amounts are included.
Additional reductions for renting a primary residence
Once the net return is calculated, the law allows an additional reduction if the property is the tenant's primary residence. This does not apply to commercial premises, offices, or tourist apartments.
New reduction percentages according to the housing law
With the recent regulations, the general reduction has risen to 50%. However, this percentage can increase to 60%, 70% or even 90% depending on various socioeconomic factors.
Renting to young people in high‑tension areas or having recently renovated the dwelling allows access to the highest brackets. Properly certifying that the apartment is the tenant's permanent residence is essential.
Are you correctly applying all your tax deductions?
Managing a lease involves much more than collecting a monthly rent. As we have seen, the correct application of deductible expenses can make a huge difference in your annual tax bill.
From the prorating of municipal taxes to the complex depreciation of the property, every detail matters. Mastering this regulation allows you to protect your profitability and comply with current legal requirements without any hiccups.
Therefore, having professional advice is the best investment for your peace of mind. You can maximize your benefits if you make sure not to leave any allowed deduction on the table.

Specifics in tourist and seasonal rentals
The rise of vacation rentals requires knowing how these specific modalities are taxed. Unlike traditional long‑term rentals, you cannot apply the state reductions of 50% or more here, as they do not meet the permanent housing need.
In these cases, the deductible rental expenses for the owner are strictly limited to the días that the property has been occupied. During the periods in which the dwelling remains vacía, you must impute property income in your tax return, without the possibility of deducting associated expenses.
What happens if you rent the property to a family member?
Renting an apartment to a spouse or a relative up to the third degree has specific tax rules. The Tax Agency establishes strict control in these cases to avoid possible simulations or leases agreed well below market price.
In this situation, the total declared net income cannot be lower than the computable minimum income. This amount generally equals 2% of the cadastral value of the property (or 1.1% if that value has been revised in the last ten years).
Therefore, even if you maximize the deductible rental expenses, the Tax Agency will always exigirá to pay that set legal minimum. It is essential to calculate beforehand whether this intra-family operation is advantageous from a strictly fiscal point of view.
Taxation for non-resident foreign property owners
If you reside outside Spain but have a rented property in the country, you do not pay tax through the Personal Income Tax (IRPF), but through the Non-Resident Income Tax (IRNR). The applicable rules vary drastically depending on your fiscal residence country.
EU resident citizens or residents of the European Unión or the European Económico Area can apply the same tax deductions for rental property owners as the españoles. The applicable tax rate on the net income obtained will be 19%.
Conversely, non-EU owners are taxed at a fixed rate of 24% on total gross income. In this scenario, the strict regulations do not allow any type of expense, nor depreciation, nor repairs, nor mortgage loan interest to be deducted.
Conclusion: Maximize the profitability of your real estate investment
Understanding thoroughly how to reduce rental apartment taxes is essential for any owner who wishes to protect their investment. A rigorous control of your invoices, contracts and bank receipts will allow you to make the most of the current tax regulations and avoid paying more.
Always remember to clearly differentiate between conservation expenses and capital improvements, apply the proration rule when appropriate, and correctly calculate the annual depreciation. These small technical details make a huge difference in the final result of your tax return.
Given the undeniable complexity of tax laws and their continuous regulatory changes, having expert advice is the smartest decision. Professional management guarantees your peace of mind, ensures strict regulatory compliance, and optimizes the real economic performance of your real estate assets.
