Buying Property in the Balearic Islands as a Non-Resident: Legal Risks and Compliance Filters

Table Of Contents

The Liquidity vs. Legality Gap

The property market in the Balearic Islands continues to attract international buyers. In locations such as Ibiza and Mallorca, demand remains strong and transactions regularly involve high-value assets.

However, in 2026 the main obstacle in many transactions is no longer financing.

It is compliance.

Many foreign buyers assume that once the funds are available, the purchase process will move quickly toward completion. In practice, the transaction must pass through a series of legal and administrative filters before the notarial deed can be signed.

Military authorisation requirements, tax exposure, anti-money laundering verification and urban legality checks now play a decisive role in determining whether a purchase proceeds smoothly or stalls before completion.

These requirements arise from several layers of Spanish legislation governing national security, tax transparency and financial supervision.

The Non-EU Bottleneck: Military Authorisation

One of the least known requirements affecting certain foreign buyers in the Balearic Islands is the need to obtain military authorisation prior to acquiring property.

This requirement derives from Law 8/1975 on Areas and Installations of Interest for National Defence, which allows the Spanish state to control property acquisitions in territories considered strategically sensitive.

The Balearic Islands fall within this category due to their geographic position in the Mediterranean.

As a result, buyers from outside the European Union may need express authorisation from the Spanish Ministry of Defence before completing a property purchase.

In practice, Spanish notaries will normally request evidence of this authorisation before executing the public deed when the buyer falls within the scope of the regulation.

Processing times may vary, and delays in obtaining the authorisation can affect contractual deadlines agreed in deposit agreements.

For this reason, many transactions involving non-EU buyers now include contractual clauses making completion conditional upon the approval of the required permit.

Fiscal Reality: The Cost of Holding Property

Non-resident ownership of Spanish property also involves a number of tax obligations that apply even when the property is not rented.

Among the most relevant are:

• Non-Resident Income Tax (IRNR), regulated by Royal Legislative Decree 5/2004
• Spanish Wealth Tax under Law 19/1991
• The temporary Solidarity Tax on Large Fortunes, introduced by Law 38/2022

The interaction between regional tax rules and national legislation means that the fiscal position of a non-resident property owner may differ significantly depending on asset value and ownership structure.

In particular, the Solidarity Tax introduced in 2022 was designed partly to ensure a minimum level of taxation on large personal assets at national level, regardless of regional tax relief schemes.

For foreign buyers unfamiliar with the Spanish system, understanding these obligations before completing the purchase is essential to assessing the long-term holding cost of the property.

Transparency Rules: Beneficial Ownership and AML Controls

Property transactions involving foreign buyers are also subject to strict anti-money laundering controls.

These controls derive primarily from Law 10/2010 on the Prevention of Money Laundering and Terrorist Financing, which requires financial institutions, notaries and other professionals to identify the ultimate beneficial owner (UBO) behind corporate structures involved in financial transactions.

In practice, this means that when property is acquired through a company, trust or other legal vehicle, the individuals who ultimately control the entity must usually be identified and documented.

Spanish banks frequently apply additional internal compliance procedures when processing high-value international transfers related to property transactions.

If the beneficial ownership structure is not sufficiently transparent, financial institutions may delay or refuse to process the transaction until the required information is provided.

As a result, ownership structures that appear complex or opaque can become a practical obstacle during the acquisition process.

Urban Legality and Planning Compliance

Urban planning compliance remains one of the most sensitive aspects of property transactions in the Balearic Islands.

Properties that include extensions, pools or guest houses built without full planning authorisation may present legal complications even when the irregularity dates back several years.

Spanish planning legislation allows administrative sanctions to expire after certain periods. However, the expiry of a sanction does not necessarily legalise the construction itself.

In protected rural areas, particularly those classified as environmentally sensitive land, planning restrictions may remain in place indefinitely.

Authorities increasingly rely on cadastral records, planning registries and historical aerial imagery to verify whether the built structure corresponds to the authorised planning permissions.

For this reason, verifying urban planning compliance before signing the purchase agreement is a key element of legal due diligence.

Scenario: When a Buyer Cannot Complete the Purchase

Consider a scenario involving a buyer based outside the European Union who agrees to purchase a property in Ibiza.

The funds are available and the parties sign a deposit agreement establishing a completion date before a Spanish notary.

However, the buyer has not yet obtained the military authorisation required under Law 8/1975.

Without this authorisation, the notary may be unable to proceed with the execution of the public deed.

If the contractual deadline expires before the authorisation is granted, the buyer may face difficulties completing the transaction within the agreed timeframe.

Situations like this illustrate how administrative requirements can influence the practical timeline of property transactions involving international buyers.

Due Diligence Has Become Central to the Transaction

Buying property in the Balearic Islands remains legally accessible to foreign buyers.

However, the regulatory environment surrounding these transactions has become more structured in recent years.

National security rules, tax transparency legislation and anti-money laundering controls now form part of the legal framework governing property acquisitions.

For non-resident buyers, understanding these regulatory filters before entering into contractual commitments can help prevent delays, disputes or financial exposure during the purchase process.

Legal due diligence is therefore no longer limited to verifying title or charges in the Land Registry.

It increasingly involves analysing the regulatory path that allows the transaction to be completed without unexpected obstacles.

FAQs – Buying Property in the Balearic Islands as a Non-Resident

Do non-EU buyers need a military permit to buy property in the Balearic Islands?

In certain cases, yes.

Under Law 8/1975 on Areas and Installations of Interest for National Defence, property acquisitions by non-EU nationals in territories considered strategically sensitive may require prior authorisation from the Spanish Ministry of Defence.

The Balearic Islands fall within the scope of this regulation. Spanish notaries may request evidence of this authorisation before completing the public deed when the transaction involves buyers subject to the rule.

How long does the property purchase process take for non-resident buyers?

The timeline varies depending on documentation requirements and the complexity of the transaction.

A standard purchase can sometimes be completed within several weeks. However, if additional procedures are required, such as military authorisation or tax registrations, the process may extend over several months.

For this reason, contractual deadlines in deposit agreements should take these administrative steps into account.

Do non-resident property owners pay tax in Spain even if they do not rent the property?

Yes.

Under the Spanish Non-Resident Income Tax regime (Royal Legislative Decree 5/2004), owners of property located in Spain may be subject to taxation based on deemed rental income, even if the property is not actually rented.

Depending on the value of the asset, other taxes such as Wealth Tax (Law 19/1991) or the Solidarity Tax on Large Fortunes introduced by Law 38/2022 may also apply.

Can property in Spain be purchased through a foreign company?

Yes, property can be acquired through a foreign company.

However, under Law 10/2010 on the Prevention of Money Laundering, financial institutions and notaries must identify the ultimate beneficial owner (UBO) behind the purchasing entity.

This means that the individuals who ultimately control the company must be properly identified during the transaction.
