New Netherlands–Spain Tax Treaty: What Dutch Property Investors Should Know

A planned change to the tax agreement between Spain and the Netherlands could have important consequences for Dutch investors who own Spanish real estate through a company. Here is what property owners and prospective investors need to know.

ough a Spanish S.L.

Some investors purchase Spanish properties through a Sociedad Limitada (S.L.), the Spanish equivalent of a limited liability company.

This company may hold a single luxury villa, several rental apartments or an entire property portfolio. In some cases, the Spanish company is owned by a Dutch holding company, such as a B.V.

When the investment is sold, there are two possible approaches:

• The company sells the property itself.
• The investor sells the shares in the company that owns the property.

Although these transactions may appear similar from an investment perspective, their tax treatment can be very different.

2. Why Selling Shares Has Traditionally Been Attractive

Under the existing Netherlands–Spain tax treaty, certain capital gains realised by Dutch tax residents when selling shares in a Spanish property company may fall under the taxing rights of the Netherlands rather than Spain.

Depending on the investor's circumstances and applicable Dutch tax rules, this has sometimes offered a favourable way to structure a real estate investment and its eventual sale.

The proposed treaty could significantly change that situation.

What Could Change Under the New Agreement?

The new treaty is expected to give Spain additional rights to tax capital gains arising from the sale of shares in companies whose value is predominantly connected to Spanish real estate.

In practical terms, this means that selling shares in a company holding Spanish property could potentially create a Spanish capital gains tax liability even when the seller is a Dutch tax resident.

The precise conditions, thresholds and exceptions will depend on the final published agreement.

This development could be particularly relevant for investors who:

• Own luxury villas or investment properties through a Spanish S.L.
• Hold Spanish real estate through a Dutch B.V. and Spanish subsidiary.
• Manage multiple properties within a corporate structure.
• Are considering selling their property company rather than individual assets.
• Plan to restructure or transfer an existing Spanish real estate investment.

Importantly, the potential change does not mean that every Dutch property owner will face additional taxation.

The structure of the investment, the seller's tax residence and the nature of the transaction will all matter.

What Does This Mean for Investors in Marbella and the Costa del Sol?

Consider a Dutch investor who owns several premium apartments in Marbella through a Spanish limited company.

Over time, the properties increase in value, and the investor eventually decides to sell the business, including its real estate assets.

Under the existing treaty, certain gains arising from a share sale may be taxable in the Netherlands rather than Spain.

Under the proposed arrangement, Spain may acquire additional rights to tax those gains.

Depending on the circumstances, the difference could materially affect the net proceeds received from the investment.

For investors managing substantial property portfolios, the potential financial implications make early planning particularly important.

Does This Affect Individual Property Buyers?

For Dutch buyers purchasing a holiday home or permanent residence in their own name, the proposed change to the taxation of company shares is generally less directly relevant.

Standard Spanish property acquisition costs, ongoing ownership taxes and taxation on a direct property sale remain separate considerations.

However, buyers planning a larger investment, acquiring multiple properties or considering corporate ownership should understand the implications before deciding how to structure their purchase.

The choice between personal and corporate ownership should be based on the complete investment picture, including tax residence, financing, rental plans, administrative costs and long-term objectives.

Five Things Dutch Property Investors Should Consider

With the new treaty still awaiting implementation, investors have an opportunity to review their position.

1. Review Your Ownership Structure

Determine whether your Spanish properties are held personally, through a Spanish S.L., through a Dutch B.V. or through another arrangement.

2. Understand Your Future Exit Strategy

Selling an individual property and selling shares in a property company are different transactions. Consider which option may be appropriate for your investment objectives.

3. Evaluate the Potential Tax Impact

Ask a qualified adviser experienced in both Spanish and Dutch taxation to assess how the anticipated changes could affect your circumstances.

4. Monitor the Treaty’s Implementation

The agreement is not yet in force. Its final provisions, effective date and any transitional arrangements should be confirmed before making decisions.

5. Think Beyond Taxation

Property location, rental potential, liquidity, market demand and long-term value remain essential elements of a successful real estate investment.

When Will the New Tax Treaty Take Effect?

As of October 2026, the Netherlands and Spain have reached an agreement in principle, but the existing treaty from 1971 remains in force.

The new agreement must complete the necessary formal procedures before it can replace the current rules.

Until its final provisions and implementation timetable are confirmed, investors should avoid making decisions based solely on anticipated tax changes.

Nevertheless, staying informed and reviewing existing structures early can help investors prepare for potential changes.
