The Spanish government announced a new measure a few days ago aimed at curbing the sharp rise in rents: landlords will be fully exempt from income tax (IRPF) if they refrain from increasing rents when contracts are renewed.

The timing is critical. In the coming months, more than 1.6 million rental contracts are due to expire, many of them in high-demand areas where rents have recently jumped by several hundred euros in a single increase.
Politically, the message is clear. Economically, however, the proposal has been met with widespread scepticism among tax specialists and housing experts.
When economic incentives outweigh political appeals
According to tax advisers, the proposed exemption is unlikely to change the behaviour of many property owners. The reason is straightforward: raising rents remains significantly more profitable than the tax benefit offered by the government.
Tax experts at bdp Team, which has its Spanish headquarters in Marbella, illustrate this with a realistic example. A property rented at €1,000 per month generates €12,000 in gross annual income. After deducting standard expenses such as property tax, community fees, insurance, maintenance costs and the legally permitted depreciation, the taxable profit is reduced to around €4,800.
With the current minimum 50% IRPF reduction, the taxable base falls to approximately €2,400, resulting in an effective tax bill of €800 to €1,000 per year. Under the new measure, this amount could be fully saved if the landlord keeps the rent unchanged.
However, if the owner raises the rent by €500 per month — a scenario already common in many Spanish cities — annual income increases by €6,000. Even accounting for a higher tax bill, the net financial gain remains substantially greater than the value of the tax exemption.
The conclusion drawn by experts is clear: from a purely financial perspective, there is little incentive for many landlords to freeze rents.
An additional risk: limited protection in cases of non-payment
Another factor often overlooked in the political debate but crucial for property owners is the risk of rent default.
In Spain, when a tenant stops paying rent, landlords have very limited and slow legal options. Eviction proceedings frequently take many months and, in some cases, more than a year. During this period, owners receive no rental income while continuing to pay mortgages, community charges, taxes and maintenance costs.
For many landlords, this reality reinforces the desire to build financial buffers or offset potential losses through higher rents, further reducing the effectiveness of tax-based incentives alone.
A contradictory incentive system
Further criticism comes from technicians at the Spanish Ministry of Finance (Gestha), who point to inconsistencies within the current tax framework.
Under existing rules, landlords in so-called “stressed areas” can benefit from a 90% tax reduction if they cut rents by at least 5% when renewing contracts. The newly announced measure, however, would grant a 100% exemption to those who simply freeze rents without reducing them.
The result is paradoxical: landlords who actively lower rents are treated less favourably than those who merely avoid an increase. According to Gestha, this undermines both the logic and credibility of the policy.
Tax policy cannot replace housing policy
Beyond technical details, many experts highlight a deeper structural issue: tax incentives cannot substitute for a coherent housing policy.
While such measures may send short-term signals, they fail to address the underlying problems:
-
they do not increase housing supply,
-
they do not expand public housing stock,
-
and they do not ease pressure in an overheated rental market.
In the long term, specialists continue to point to the need for affordable housing development, direct rental support, and clear, stable regulation, even if these solutions are more politically complex and costly.
Frozen rents are not necessarily affordable
Tenant organisations also argue that the tax exemption applies even where rents have already reached unsustainable levels for many households.
The figures underline the concern: in Spain, rent absorbs an average of 47% of gross income. In Madrid, the figure exceeds 70%, while in Barcelona and the Balearic Islands it stands at around 60–65%. Under such conditions, freezing prices does little to solve the core issue — a lack of affordability.
Strong headlines, limited impact
The full IRPF exemption comes at a moment of mass contract renewals and has generated strong political headlines. Yet tax experts, housing specialists and social organisations largely agree that it is unlikely to alter the behaviour of most landlords.
As long as rent increases remain more financially attractive than tax incentives — and landlords continue to face weak protection in cases of non-payment — the impact of the measure is expected to be limited. Once again, Spain’s rental market highlights a familiar pattern: ambitious political announcements with modest real-world effects.
