A SOCIMI (Sociedad Anónima Cotizada de Inversión en el Mercado Inmobiliario) is Spain's equivalent of a Real Estate Investment Trust (REIT). Introduced in 2009 and significantly reformed in 2012, the SOCIMI regime provides a highly tax-efficient vehicle for investing in rental real estate, provided certain regulatory requirements are met.
The SOCIMI regime is primarily used by institutional investors and family offices investing in commercial real estate — offices, shopping centres, residential portfolios, logistics warehouses, hotels, and student accommodation. SOCIMIs are listed on regulated markets or multilateral trading facilities (including the MAB/BME Growth market), which is a core requirement of the regime.
The headline feature of the SOCIMI regime is a 0% CIT rate on income derived from qualifying activities — principally rental income and capital gains from the disposal of qualifying assets. This compares to the standard 25% CIT rate applicable to ordinary Spanish companies.
However, this 0% rate comes with an important caveat: the SOCIMI must distribute at least 80% of rental income, 50% of capital gains from asset disposals, and 100% of income from dividends received from qualifying subsidiaries. The distribution requirement is what makes the SOCIMI a "flow-through" vehicle — the tax liability is effectively moved to the investor level.
A reform introduced in 2020 added an important tax charge for cases where a SOCIMI's shareholders are not themselves subject to taxation on dividends received. Specifically, where a SOCIMI has a shareholder who holds 5% or more of the share capital and who pays less than 10% tax on the dividends received from the SOCIMI, the SOCIMI itself is subject to a 19% special levy on the dividends distributed to that shareholder.
This provision — sometimes called the "anti-abuse" or "fiscal resident" rule — was aimed at preventing SOCIMIs from being used as efficient dividend conduits for investors in jurisdictions with 0% or very low dividend taxation. It has significant implications for structuring.
For individual investors (whether Spanish residents or non-residents), SOCIMI dividends are treated as investment income and taxed at the savings income rates (19%–28% for Spanish residents under IRPF). For non-resident investors, the standard withholding rate under Spanish Non-Resident Income Tax (IRNR) applies — typically 19% for EU residents, or a reduced DTA rate for investors from treaty countries.
Capital gains on the disposal of SOCIMI shares by non-resident investors are exempt from Spanish IRNR in many cases — subject to the anti-abuse conditions and DTA provisions.
To maintain SOCIMI status, the company must meet ongoing requirements relating to its asset base and activity:
While large institutional SOCIMIs are listed on the main Spanish market, family offices and private investors typically use the BME Growth (formerly MAB) listing route, which has lower admission requirements and is accessible for portfolios of meaningful but not institutional scale.
A typical private SOCIMI structure involves:
Shareholders holding 5%+ through a low-tax structure may trigger the 19% SOCIMI-level charge. Structure your shareholding carefully with respect to your jurisdiction's dividend taxation rate.
Only Spanish SAs qualify as SOCIMIs. The minimum share capital is €5m, and the shares must be listed. This makes the regime unsuitable for very small portfolios.
Assets disposed of before 3 years of SOCIMI ownership are subject to standard CIT rates. Exit planning should account for this holding period requirement.
If the SOCIMI forms part of a group, related-party transactions (management fees, financing) must comply with arm's-length transfer pricing rules. The STA scrutinises SOCIMI-group transactions closely.

Investors and fund managers must understand what happens when a SOCIMI fails to meet its ongoing qualifying requirements — a scenario known as incumplimiento de requisitos. The consequences are severe enough that exit planning should begin at the moment of structuring, not at the point of departure.
A SOCIMI loses its special tax regime if it fails to satisfy any of the following on a persistent basis: the 80% asset composition test, the mandatory distribution obligations (80% of rental income, 50% of capital gains, 100% of dividends received), the listing requirement, or the 3-year asset holding condition for a significant portion of its portfolio. A breach of the listing requirement — for example, delisting from BME Growth — immediately disqualifies the vehicle from the date of delisting.
Spanish law (Art. 11 Ley 11/2009) grants a SOCIMI a 2-year cure period to remedy non-compliance before the loss of regime becomes definitive. If the breach relates to the asset composition test or income test, the SOCIMI has until the end of the second tax year following the year in which the breach was first identified to restore compliance. This grace period does not apply to wilful non-distribution or to a deliberate delisting.
Where SOCIMI status is lost — whether by failure to cure or by voluntary exit — the company reverts to the standard Spanish CIT regime at 25%. Critically, a penalty applies: all income and gains that were taxed at 0% during the SOCIMI years become subject to a regularisation charge equal to the difference between 0% (paid) and 25% (standard) on those historical profits, plus late payment interest accrued from the date the income was originally earned. In practice, this can represent a large back-tax liability on assets that appreciated significantly during the SOCIMI period.
For investors, loss of SOCIMI status affects the future dividend flow (which had benefited from the pass-through regime) and the capital value of their shares. If the SOCIMI's effective tax burden increases from 0% to 25%, the after-tax distributable income falls correspondingly, reducing the dividend yield and the underlying NAV of the vehicle. Shareholders who invested based on SOCIMI economics should monitor compliance carefully — particularly the listing status and distribution track record.
The table below compares the tax position of a SOCIMI holding a €2 million Spanish commercial property generating €100,000 per year in gross rental income against direct property ownership by a Spanish company, for a Spanish resident individual investor:
| Tax Item | SOCIMI Structure | Direct Property (Spanish Company) |
|---|---|---|
| Corporate tax on rental income | 0% (SOCIMI regime) | 25% CIT → €25,000/year |
| Distributable rental income (net of corporate tax) | €100,000 | €75,000 |
| WHT on dividends (Spanish resident) | 19% on distributed amount → €19,000 | 19% on distributed amount → €14,250 |
| Net income to investor after all taxes | €81,000 | €60,750 |
| Special 19% SOCIMI levy (if applicable) | €19,000 payable by SOCIMI (if shareholder <10% taxed) | N/A |
| Capital gains on 3-year+ asset disposal | 0% CIT at SOCIMI level | 25% CIT on gain |
| Capital gains on share disposal (investor) | 19–28% IRPF on gain over cost | 19–28% IRPF on gain over cost |
On a €100,000 annual rental income, the SOCIMI structure delivers approximately €20,250 more net income per year to the investor compared with a standard corporate holding — assuming no triggering of the 19% special levy. Over a 10-year hold on a €2 million property portfolio, this differential compounds substantially. The SOCIMI advantage narrows if the 19% special levy applies, and disappears entirely if the SOCIMI loses its status and reverts to standard CIT.
Non-resident investors face a distinct set of considerations when investing in SOCIMIs, shaped by the interaction between Spanish domestic law, applicable double tax treaties (DTAs), and EU law principles.
SOCIMI dividends paid to non-resident shareholders are subject to Spanish IRNR (Impuesto sobre la Renta de No Residentes) withholding at the domestic rate of 19%. This rate can be reduced under an applicable DTA. For example, under the Spain-UK DTA dividends may be reduced to 10–15% depending on the shareholding percentage; under Spain-US the general rate is 15%, reduced to 5% for qualifying corporate shareholders holding 10%+ of voting shares. EU/EEA shareholders may benefit from additional protections under the EU Parent-Subsidiary Directive where the relevant conditions (10% holding, 1-year minimum) are met, potentially reducing WHT to 0% on qualifying distributions.
EU-resident investors benefit from free movement of capital protections under Art. 63 TFEU. Spain cannot impose discriminatory withholding on EU shareholders without objective justification. Non-EU investors have no such treaty protection and are entirely dependent on the applicable DTA (or the domestic 19% rate if none exists). Investors from jurisdictions with no DTA with Spain — certain LATAM countries, some Middle Eastern jurisdictions, and others — pay the full 19% IRNR on SOCIMI dividends.
Non-resident investors disposing of SOCIMI shares may benefit from a capital gains exemption under Spanish IRNR, provided the gain does not arise from shares in a vehicle more than 50% backed by Spanish real estate and the disposal is not treated as an indirect transfer of Spanish real estate. In practice, SOCIMIs — as real-estate-backed vehicles — often do not qualify for this exemption, making DTA capital gains provisions (and the specific DTA real estate article) critical to planning the exit of a non-resident SOCIMI investment.
