Spain’s proposed 100% complementary tax would apply only to resale properties purchased by non-EU/EEA buyers, not new builds. As of March 2026, the measure remains in parliamentary debate and is not yet law. New build purchases are exempt because they use VAT instead of transfer tax, making them unaffected by this proposal.
In May 2025, Spain’s government proposed a landmark tax policy that sent shockwaves through the international property market. The 100% complementary tax on non-EU property purchases represents one of the most significant changes to Spain’s property laws in recent years. For Costa Blanca buyers — where over 43% of purchases involve foreign nationals — understanding this proposal is critical to your investment strategy. This guide explains what the tax actually is, who it affects, and why new build buyers have good reason to breathe easier. Read on to discover how to protect your Costa Blanca purchase regardless of the tax outcome.
What Is Spain’s Proposed 100% Tax on Non-EU Buyers?
Spain’s Socialist government (PSOE) proposed a new complementary tax targeting property purchases by buyers from outside the EU and European Economic Area. This is not a replacement for existing taxes — it sits on top of current Transfer Tax (Impuesto sobre Transmisiones Patrimoniales, or ITP). The complementary tax is calculated at 100% of the taxable base, which means it doubles the tax burden for affected buyers on resale properties. For example, if a property’s cadastral value is €300,000, the complementary tax could add another €300,000 in tax liability on top of the standard ITP (which ranges from 6-10% depending on the region). This makes the total tax burden on resale property purchases potentially catastrophic for non-EU buyers.
Who Is Affected by This Tax?
The proposed tax applies to property buyers from countries outside the EU and EEA. This includes: UK nationals (post-Brexit), US citizens, Canadian buyers, Chinese investors, and buyers from Latin American countries. Notably, the tax does not affect EU and EEA citizens, meaning buyers from Germany, France, Italy, Scandinavia, and the Netherlands remain unaffected. This creates a significant disparity in the Costa Blanca property market, where British expats have historically represented a major buyer demographic. The tax also does not affect Spanish nationals or residents with legal residency status purchasing property.
The Critical Exemption: Why New Builds Escape This Tax
Here is the most important detail for Costa Blanca property buyers: new builds and off-plan properties are completely exempt from the proposed 100% complementary tax. Why? Because new builds are taxed under a different system. They use VAT (IVA — Impuesto sobre el Valor Añadido) rather than Transfer Tax (ITP). Since the complementary tax is designed as a supplement to ITP, it does not apply to properties using the VAT system. This distinction is crucial for your strategy. If you purchase a newly constructed property or buy off-plan from a developer, you pay VAT (typically 10% on new builds) plus other costs, but you avoid the proposed complementary tax entirely. This makes new build purchases inherently more tax-predictable and protects your investment regardless of whether this proposal becomes law.
Current Status: Still in Parliamentary Debate
As of March 2026, the 100% complementary tax remains a proposal in Spanish parliamentary debate. It has not yet been enacted into law. While the Spanish government has pushed for its adoption, legislative progress has been slower than initially anticipated. The measure faces several hurdles: political opposition, practical implementation challenges, and potential legal challenges under EU law. Some economists and property market analysts argue that such a high tax could violate EU free movement of capital principles, which guarantee equal treatment of capital movements between member states and third countries. Until the law is formally passed, property buyers should monitor developments but not make decisions based on assumptions. The current legal framework remains unchanged.
Impact on Costa Blanca: A Market Reality Check
Costa Blanca has long been characterized as Spain’s most international property market. Foreign buyers account for 43% or more of all property transactions in the region, with British, German, Scandinavian, and American buyers particularly active in Benidorm, Torrevieja, and Alicante. A 100% complementary tax on non-EU buyers would fundamentally reshape market dynamics. Property prices could fall as non-EU buyers seek alternative markets or recalculate their investment returns. Developers might adjust marketing strategies, and the competitive advantage for EU and Spanish buyers would increase dramatically. However, this scenario assumes the tax becomes law in its proposed form. In practice, political negotiations often result in modified versions of proposed legislation, and exemptions (like the new build exemption already built into this proposal) may expand.
Your Strategy: New Builds Offer Tax Certainty
Regardless of whether Spain’s proposed 100% tax becomes law, new builds and off-plan properties offer significant advantages for non-EU buyers seeking tax certainty. By purchasing off-plan or newly constructed properties, you bypass the complementary tax risk entirely. New builds offer additional benefits beyond tax protection: they come with 10-year structural guarantees, modern energy efficiency, no hidden defects, and often superior financing terms. Many Costa Blanca developers offer flexible payment plans spread over the construction period, reducing upfront capital requirements. Additionally, new build purchases support Spanish employment and economic development, which may provide political goodwill if tax disputes arise. For non-EU buyers, choosing new builds is not just a tax strategy — it’s a comprehensive risk mitigation approach.

How This Compares to Other Countries’ Foreign Buyer Taxes
Spain is not the first country to consider foreign buyer taxes. Canada, Australia, New Zealand, and some US states have implemented foreign buyer surcharges. However, Spain’s proposed 100% rate is exceptionally high — far exceeding most international precedents. Canada’s foreign buyer tax, for example, sits at 15% in Ontario and 20% in British Columbia. Australia’s foreign buyer surcharge ranges from 4-8% depending on the state. Spain’s proposal at 100% represents a fundamentally different approach, effectively doubling the already substantial transfer tax burden. This suggests Spain’s government views the tax as a tool not just for revenue generation but also for discouraging non-EU property ownership. If implemented, it would rank among the world’s harshest foreign buyer taxes and could make Spain less competitive internationally compared to Portugal, Italy, or Greece, which offer more favorable tax treatment to foreign investors.
Frequently Asked Questions
Q: Does this tax apply to properties I already own? A: No. The proposed tax would only apply to future purchases made after the law takes effect. Existing properties are not subject to retroactive taxation.
Q: Am I affected if I have Spanish residency? A: If you have legal residency in Spain (empadronamiento), you may be treated as a Spanish resident for tax purposes, potentially exempting you from the complementary tax. Consult a Spanish tax advisor for your specific situation.
Q: What about inherited or gifted properties? A: The proposal as currently drafted focuses on purchases. Inherited properties typically follow different tax rules (inheritance tax rather than transfer tax), and gifted properties may have different treatment. Details remain unclear in the ongoing parliamentary debate.
Q: Can I still get a mortgage as a non-EU buyer if this passes? A: Yes. Spanish banks typically base lending decisions on property value and buyer creditworthiness, not nationality. However, higher total costs (including the complementary tax) might affect loan-to-value ratios and borrowing capacity.
Q: Should I rush to buy now before the tax passes? A: If you’re ready and have found the right property, purchasing sooner rather than later eliminates tax uncertainty. However, don’t make rushed decisions based on tax speculation. Focus on finding properties that match your needs. If you’re interested in new builds specifically, you remain protected regardless of this tax’s fate.
Q: How do I calculate the potential tax impact on a resale property? A: For resale property, total transfer costs typically include ITP (6-10% depending on region), plus notary fees (0.2-0.5%), plus land registry fees (0.1-0.2%). If the complementary tax passes, add another 100% of the cadastral value as a separate tax. Working with a property lawyer or tax advisor is essential for accurate calculations specific to your purchase.
Q: What about Stamp Duty for UK buyers? A: UK buyers should distinguish between Spanish transfer tax and UK stamp duty. You may face UK obligations depending on your residency status, but Spanish transfer tax/ITP is the primary concern for Spain-side costs. Consult a cross-border tax advisor familiar with UK-Spain property transactions.
Q: Are there any other foreign buyer restrictions I should know about? A: Spain does not have a blanket foreign buyer ban like some countries. The main restriction affects agricultural land purchases by non-EU buyers in some regions. Foreign buyer registration is straightforward, and non-residents can own property. The proposed complementary tax is an economic barrier, not a legal prohibition.
Next Steps for Costa Blanca Buyers
Whether you’re a British expat, Scandinavian investor, or international buyer considering Costa Blanca, here’s what you should do now. First, if you’re interested in resale properties, monitor developments on this tax proposal but don’t let uncertainty paralyze your decision-making. Work with a local property lawyer experienced in international transactions to understand your specific tax position. Second, seriously consider new builds and off-plan properties as a tax-efficient strategy. They offer protection from this proposed tax plus significant additional benefits (warranties, modern construction, financing flexibility). Third, explore all property-related costs and taxes comprehensively so you’re not blindsided. Finally, if you’re a British expat planning a long-term move to Spain, understand how the British buyer landscape has changed post-Brexit and how residency status affects your tax obligations. Costa Blanca remains an attractive market with strong fundamentals — don’t let one proposed tax policy overshadow your investment opportunity.
Conclusie
Spain’s proposed 100% complementary tax on non-EU property purchases is significant, but it’s not yet law, and it doesn’t affect new builds. For Costa Blanca buyers, this means the strategy is simple: if you want tax certainty and strong property fundamentals, choose off-plan or newly constructed properties. They offer complete protection from this tax plus superior warranties and modern construction. Regardless of the tax outcome, your new build investment remains secure.
