The short answer: Yes, Spain capped rent increases at 2% per year for all residential leases, effective March 24, 2026, under Royal Decree-Law 8/2026. This applies to every landlord — individual or corporate — across the entire country, with no distinction for property size or stressed-market zones. It runs until December 31, 2027.
If your lease review date falls after March 24, 2026, you cannot increase rent by more than 2%, regardless of what index your contract references. If your tenant’s lease expires before end-2027 and all standard extensions are used up, they can demand up to two more years at the same rent.
Read on for the full breakdown: who’s affected, what the official decree says, how it interacts with CPI and IRAV, what it means for non-resident landlords and Beckham Law holders, and what happens from 2028.
What is RDL 8/2026 — Official Source and Full Text
Real Decreto-ley 8/2026, of March 24, 2026, was approved by the Council of Ministers under the constitutional emergency legislative procedure (Article 86 of the Spanish Constitution). It was published in the Boletín Oficial del Estado (BOE) on the same date and entered into force immediately on publication.
The official BOE reference is: Real Decreto-ley 8/2026, de 24 de marzo, por el que se adoptan medidas urgentes en materia de alquiler de vivienda — searchable at boe.es.
The decree introduces two measures:
- Article 1 — Extraordinary extension of habitual residence leases for up to 2 additional years, at the tenant’s request, once all standard LAU extensions are exhausted.
- Article 2 — A 2% ceiling on annual rent updates for all habitual residence leases, replacing any higher index written into the contract.
Both measures apply until December 31, 2027, nationwide.
Why an emergency decree?
The Government invoked extraordinary and urgent necessity on the basis that housing affordability has deteriorated significantly in Spanish cities. This is the fourth consecutive intervention in the residential rental market via emergency decree since 2020 — following RDL 11/2020 (COVID moratorium), RDL 6/2022 (first 2% cap for large holders), and RDL 11/2022 (extended to all landlords). Each has been ratified by the Congreso de los Diputados within the constitutionally required 30-day window.
Rent Increase Cap for 2026: Is it 2%, 3%, or 5%?
This is the most searched question — and the answer depends on the time period:
| Period | Cap | Legal Basis |
|---|---|---|
| 2022 (large holders) | 2% | RDL 6/2022 |
| 2022–2023 (all landlords) | 2% / 3% | RDL 11/2022, RDL 1/2023 |
| 2024 | 3% transitional | Ley 12/2023 |
| Jan 2025 – Mar 2026 | IRAV index (INE) | Ley 12/2023 |
| From March 24, 2026 | 2% | RDL 8/2026 |
| From Jan 2028 (unless extended) | IRAV index | Ley 12/2023 |
From March 24, 2026 onward: the cap is 2%. Not 3%, not 5%. Any reference to those figures applies to the prior regulatory periods.
The IRAV (Índice de Referencia para la Actualización de Contratos de Arrendamiento de Vivienda) is the permanent index established by Ley 12/2023 (Ley de Vivienda). RDL 8/2026 overrides it temporarily. If IRAV falls below 2% on a given review date, the lower IRAV figure applies — the cap works as a ceiling, not a floor.
Who’s Affected: Existing Leases vs New Contracts
Existing leases
All habitual residence leases regulated by Ley 29/1994 (LAU) are subject to the 2% cap on any annual rent update falling on or after March 24, 2026. This includes:
- Leases signed years before the decree
- Leases that reference CPI, IRAE, IRAV, or any other index in the contract text
- Leases in both stressed and non-stressed residential zones
- Leases held by individual landlords and by corporate landlords (companies, funds, SOCIMIs)
If your annual review date arrived after March 24, 2026 and you have already applied an increase above 2%, you must correct it and refund the excess.
New contracts
New residential leases signed after March 24, 2026 are not subject to the 2% cap on the initial rent — the parties can agree any market rent at the outset. However, the subsequent annual updates during the decree’s validity are capped at 2%.
In stressed residential market zones declared under Ley 12/2023, additional restrictions apply to new contracts: the initial rent may not exceed the reference price published by the Ministry of Housing, regardless of RDL 8/2026.
Excluded tenancy types
- Commercial leases (premises, offices, warehouses)
- Seasonal leases (temporary use, not habitual residence)
- Room rental agreements
- Tourist and holiday lets
Landlord Compliance Checklist
Use this checklist to verify compliance from March 24, 2026:
- Identify all review dates across your portfolio that fall on or after March 24, 2026
- Recalculate permitted increases: apply IRAV or 2%, whichever is lower
- Issue a corrected notice to any tenant who received a notice above 2% after March 24
- Refund excess amounts charged since the decree came into force (with statutory interest)
- Check contract expiry dates: if any lease exhausts all LAU extensions before end-2027, prepare for a possible extraordinary extension request from the tenant
- Document personal occupancy need if you intend to oppose an extension on that ground — generic statements are insufficient; you need verifiable evidence
- Review standard contract templates to ensure annual update clauses reference the correct regulatory framework
- Engage a property manager or legal advisor if you have multiple units — systematic non-compliance attracts fines of EUR 3,000 to EUR 90,000 under Ley 12/2023
Tax Implications: Non-Resident Landlords and Beckham Law Holders
This is the section most relevant to BMC’s client base — foreign investors, expats, and internationally mobile professionals with rental property in Spain.
Non-resident landlords (IRNR)
If you are not a Spanish tax resident and you let out a property in Spain, your rental income is taxed under the IRNR (Impuesto sobre la Renta de No Residentes):
- Non-EU/EEA landlords: taxed at 24% flat on gross rental income — no expense deductions permitted
- EU/EEA resident landlords: taxed at 19% on net income (expenses deductible in proportion to rental days)
The 2% rent cap directly compresses gross income. For non-EU landlords who cannot offset costs, the cap reduces the taxable base and the tax bill — but it also reduces net cash yield simultaneously, with no relief mechanism.
Non-resident landlords must file quarterly IRNR returns (Modelo 210) for each quarter in which rental income accrues.
Beckham Law holders (Ley Beckham / Art. 93 LIRPF)
The Beckham Law is the Spanish special tax regime for inbound workers and their families (Article 93 LIRPF), applicable for up to 6 years from the year of arrival. It taxes Spanish-source income at a flat 24% rate (up to EUR 600,000).
Key considerations for Beckham Law holders with rental property in Spain:
- Rental income from Spanish property is taxed at 24% flat — not the standard IRPF progressive scale
- The 2% cap means the taxable rental income grows more slowly than inflation, which partially offsets the regime’s tax efficiency
- If the property is the habitual residence of the Beckham Law holder themselves, RDL 8/2026 restrictions on rent updates do not apply (owner-occupied, not let)
- If the property is let to a third party, the cap applies fully — and the 24% flat rate on compressed income means yield planning becomes more important
Beckham Law holders with rental portfolios should model cash-flow projections under the 2% cap scenario through 2027 and assess whether to exit, hold, or restructure before the transitional period ends.
When to get specialist advice
If any of the following apply, seek specialist advice before your next rental review or filing date:
- You hold Spanish rental property as a non-resident
- You are on the Beckham Law (or considering applying)
- You own rental property through a Spanish or foreign company
- Your property is in a stressed zone (reference price restrictions apply)
- You are considering selling — capital gains for non-residents are taxed at 19% under IRNR, and the rental income history affects cost basis calculations

Context and Background: An Intervention Five Years in the Making
RDL 8/2026 is not an isolated measure. It forms part of a chain of emergency legislative interventions that began with Real Decreto-ley 11/2020, of March 31, approved in the context of the COVID-19 pandemic. That decree introduced the first extraordinary extension of habitual residence lease contracts — then limited to six months — and established the first rent modulation mechanisms for situations of vulnerability.
The second phase came with successive extensions of the rent containment indices that the Government approved from 2022 onwards, when inflation pushed the CPI above 10%. Real Decreto-ley 6/2022 capped the update ceiling at 2% for large holders and at the negotiated increase for small landlords during 2022. RDL 11/2022 extended that regime and for the first time introduced a universally applicable 2% cap, regardless of landlord size. RDL 1/2023 maintained the cap at 3% for 2023 and created the Índice de Referencia para Actualización de Arrendamientos (IRAE — Reference Index for Rent Updates), which in January 2025 definitively replaced the CPI as the statutory reference index for residential leases.
The third milestone was Ley 12/2023, of May 24, on the right to housing (the Ley de Vivienda), which permanently introduced the stressed residential market zone system, the expanded definition of large holder (five or more properties in a stressed zone), the Reference Price Index, and the specific restrictions applicable in those zones. The Ley de Vivienda, however, made much of its practical effect conditional on the declaration of stressed zones by the autonomous communities — a process that has progressed unevenly.
RDL 8/2026 now takes a different position: rather than restricting its application to stressed zones or large holders, it establishes the 2% cap and the extraordinary extension as measures of general application across the entire national territory. In that sense, it is the broadest intervention in the residential rental market since the Ley de Arrendamientos Urbanos of 1994.
Article 1: The Mandatory Extraordinary Extension
Article 1 of RDL 8/2026 provides that where a habitual residence lease has exhausted the mandatory extension periods under Articles 9 and 10 of Ley 29/1994, of November 24, on Urban Leases (LAU), and the contractual expiry falls before December 31, 2027, the tenant may request from the landlord an extraordinary extension of up to two years under the same conditions as the current contract.
Extension mechanics. The request must be made in writing at least two months before the contract’s expiry date. The landlord is required to accept it, unless the ground of personal need of the property for the landlord’s own use or that of first-degree relatives — as provided for in Article 9.3 LAU — applies. Under no circumstances may the landlord demand different economic conditions from those in the current contract, or make the extension conditional on the signing of a new lease.
Personal scope. The extension applies to habitual residence leases entered into under the LAU, regardless of the date of signing. Leases for non-residential use, seasonal leases, and room rental agreements are excluded.
Interaction with contracts currently in force. For contracts still within the mandatory extension period under Article 9 LAU (up to five years if the landlord is a natural person; up to seven years if a legal entity) or within the tacit extension period under Article 10 LAU (three additional years), RDL 8/2026 adds no further period. The extraordinary extension is only triggered once all ordinary LAU extension mechanisms have been exhausted.
Practical effect. A lease signed in March 2021 by an individual landlord completed its five-year mandatory extensions in March 2026 and is now in the tacit extension period under Article 10. If the tenant does not wish to vacate and the landlord attempts to recover the property before December 31, 2027, RDL 8/2026 allows the tenant to demand the extraordinary extension and remain in the property until March 2028 — assuming they request the maximum two-year extension.
Article 2: The 2% Cap on Annual Rent Updates
Article 2 of RDL 8/2026 provides that, during the period between the decree’s entry into force and December 31, 2027, the annual update of rent under habitual residence leases may not exceed 2%, regardless of the reference index agreed in the contract and regardless of the landlord’s size.
Universal application. Unlike the measures in force during 2022 and 2023, which distinguished between large holders and small landlords, the 2% cap is now uniform and applies to all landlords: natural persons, companies, investment funds, and SOCIMIs. This uniformity is the most significant innovation compared to the previous regulatory framework.
Nullity of contrary agreements. Any contractual clause or subsequent agreement between the parties that establishes an update exceeding 2% during the validity of RDL 8/2026 is null and void. The landlord may not make the renewal of the contract, the carrying out of works, or any other performance conditional on acceptance of a higher update.
Concrete calculation. If the monthly rent is EUR 1,200 and the IRAVE applicable on the update date yields an increase of 4%, the maximum permitted update is 2%: the new monthly rent may not exceed EUR 1,224. The difference of EUR 24 per month (EUR 288 per year) cannot be recovered in subsequent years or passed on in the price of a potential new contract.
If the monthly rent is EUR 900 and the IRAV stands at 1.8%, the IRAV applies (1.8%), as it is below the 2% cap. The cap operates as a ceiling, not as a fixed update rate.
Date of application. The cap applies to all updates accruing from the date RDL 8/2026 entered into force, including those communicated to the tenant before that date but not yet executed.
Does RDL 8/2026 Apply to You? Decision Tree
The following sets out the logic for applying the decree’s measures depending on the contractual situation:
To determine whether the 2% cap applies to you:
- Is your lease a habitual residence contract regulated by the LAU? If not, RDL 8/2026 does not affect you (commercial premises, offices, seasonal leases).
- Has an annual rent update date occurred since the decree entered into force? If yes, the 2% cap applies regardless of what was agreed in the contract.
- Would the index agreed in the contract yield an increase below 2%? If yes, the agreed index applies. The cap only operates when the index exceeds 2%.
To determine whether the extraordinary extension applies to you:
- Has your contract exhausted the mandatory extensions under Article 9 LAU and the tacit extension under Article 10 LAU? If not, the extraordinary extension under RDL 8/2026 is not yet applicable; the ordinary LAU extension provisions apply.
- Does the contract expire before December 31, 2027? If it expires after that date, the extraordinary extension under RDL 8/2026 does not apply.
- Is the property needed for the landlord’s own use or that of their first-degree relatives? If yes, the landlord can oppose the extension by evidencing that need in accordance with Article 9.3 LAU.
- If no ground of need exists, the landlord is required to accept the extension for the period requested by the tenant, up to a maximum of two years.
Impact by Party Type
Individual Landlords
Landlords with one or a small number of rental properties are the group most directly affected by the 2% cap in terms of gross yield. With the CPI or IRAV historically above 2% in recent years, the gap between the cost of living and rental income widens year by year for as long as the measure remains in force.
Recommended actions: review all rent update dates across your portfolio to correctly apply the cap from the decree’s entry into force; document any update communication in writing; and assess, where a contract is approaching expiry, whether a ground of personal need exists to oppose the extraordinary extension. If you intend to rely on that ground, it must be evidenced in a reliable and verifiable manner — a generic communication is insufficient.
From a tax perspective, the deduction for income from the residential letting of habitual residences (currently 60% under the general regime of the LIRPF; 90% in stressed zones under certain conditions) is applied to net income, meaning the impact of the cap feeds through proportionally into the taxable base.
Tenants
RDL 8/2026 provides tenants with two concrete protections: certainty over rental costs — rent cannot rise by more than 2% per year — and security of tenure — they can extend the lease for up to two additional years once the LAU no longer protects them.
To benefit from the extraordinary extension, the tenant must request it expressly and in writing at least two months before expiry. A common mistake is to wait until the last moment or to fail to formalise the request in writing, which can give rise to disputes about whether the extension was validly requested in time. The recommended approach is to use a certified letter with acknowledgement of receipt or an email with a read receipt.
Tenants should bear in mind that the extension is granted on the same terms as the current contract: no better rent, no better conditions — but no worse ones either. The landlord cannot use the extension as an opportunity to introduce contractual amendments.
Investors and SOCIMIs
Sociedades Anónimas Cotizadas de Inversión en el Mercado Inmobiliario (SOCIMIs — Spanish real estate investment trusts) with residential rental portfolios need to review their financial models urgently. The impact operates through three channels:
Revenue. Rent updates are capped at 2% until the end of 2027, regardless of movements in the IRAV or CPI. This compresses organic rental income growth (like-for-like rental growth) — the primary tracking metric used by real estate equity analysts.
Turnover. Extraordinary extensions reduce the ability to release units at contract expiry for re-letting at market rates. This lower turnover negatively affects the capacity to reposition the portfolio upwards.
Special tax regime. SOCIMIs are required to distribute at least 80% of profits from rental income. If margin compression reduces distributable profit, the mandatory dividend distribution falls proportionally, which may affect market valuation and the attractiveness of the stock to income-focused investors.
For real estate investment funds and private capital vehicles with residential portfolios, the analysis is equivalent: return models that assumed rent increases above 2% need to be revised, and hold periods must be extended to absorb the impact of the cap.
Property Managers
Registered property managers (administradores de fincas colegiados) are the operational execution point for these measures. Their practical responsibilities include:
- Identifying, within each managed portfolio, the contracts with update dates falling within the period of validity of RDL 8/2026 and recalculating the applicable increases.
- Managing extraordinary extension requests received in writing from tenants, verifying that the formal and timing requirements are met.
- Advising landlords on the viability of invoking a ground of personal need where one exists, and on the documentation required to support that ground in the event of a legal challenge.
- Reviewing the standard contract templates used for new leases to ensure that rent update clauses are drafted consistently with the current regulatory framework.
Common Misconceptions and Clarifications
“The 2% cap only applies in stressed zones.” This is incorrect. RDL 8/2026 applies the 2% cap across the entire national territory, regardless of whether the property is in a stressed residential market zone declared under Ley 12/2023. Stressed zones are subject to additional restrictions — such as the Reference Price Index for new contracts — but the 2% cap on periodic updates is a measure of general application.
“It only affects large holders.” Incorrect. RDL 11/2022 was the first to establish a universal 2% cap regardless of landlord size, and RDL 8/2026 maintains that structure. There is no distinction between landlords with one property and those with one hundred for the purpose of applying the cap.
“If my contract references the CPI, I can apply the CPI.” Incorrect during the validity of RDL 8/2026. From January 2025, the IRAV replaced the CPI as the statutory reference index for residential leases. If the contract was signed before that date and references the CPI, the applicable update is the lowest of: CPI, IRAV, or 2%. Under no circumstances may it exceed the 2% legal cap.
“The extraordinary extension is automatic.” It is not. The tenant must request it expressly and in writing. If the tenant fails to request the extension within the required timeframe, the contract may terminate in accordance with the LAU.
Procedural Perspective: What Happens If the Landlord Does Not Comply
If the landlord applies a rent increase above 2%, the tenant may claim repayment of the excess amounts charged by way of a verbal tenancy proceedings claim (juicio verbal de arrendamiento) before the Juzgado de Primera Instancia. The limitation period is five years under Article 1964 of the Código Civil. Amounts charged in excess accrue statutory interest from the date of the wrongful charge.
If the landlord refuses the extraordinary extension without justification, the tenant may seek interim measures to maintain possession of the property while the declaratory proceedings are conducted. The court may order the suspension of any eviction process pending the outcome of the proceedings.
Landlords who systematically fail to comply with these obligations may also incur administrative housing violations under Ley 12/2023, with fines ranging from EUR 3,000 to EUR 90,000 depending on the severity of the breach and the type of landlord.
Validity and Political Risk
RDL 8/2026 is in force until December 31, 2027. On that date, absent an extension or legislative amendment, the residential rental market would once again be governed exclusively by the regime of Ley 12/2023 and the LAU. The experience of the past five years — in which none of the emergency decrees has expired without being extended or replaced — suggests that regulatory uncertainty is itself a risk that investors must factor into their valuation models.
The decree must be ratified by the Congreso de los Diputados within thirty days of its publication in the BOE. If it is not ratified, it would be repealed with retroactive effect from the date of publication — although actions already taken in reliance on it would be left in a state of legal uncertainty that the courts would need to resolve on a case-by-case basis.
RDL 8/2026 substantially alters the economic and temporal terms of habitual residence leases in Spain for the next two financial years. Whether you are a landlord who needs to calculate the correct rent update, a tenant who wishes to exercise your right to an extraordinary extension, or a manager of a real estate portfolio with direct exposure in your financial projections, we recommend reviewing your contractual position with appropriate care.
