Who has never dreamed of a warm Spanish home nestled between the sea and the sun? More and more Belgian families and investors are taking the plunge, drawn by the idea of enjoying an exceptional quality of life on the Costa Blanca. Spain is attractive not only for its enchanting setting, but also for the many advantages it offers in terms of non-resident taxation, in particular thanks to international tax treaties and favourable schemes for expatriates.
Why is the Costa Blanca so popular with Belgian buyers?
The Costa Blanca is renowned for its mild climate all year round, its golden beaches and its easy access from Belgium via direct flights or good road connections. Local communities warmly welcome newcomers, creating an ideal environment to settle or invest without any major culture shock.
Alongside the Mediterranean lifestyle, prices per square metre remain competitive compared with other regions of southern Europe. This attractive positioning makes it possible to buy a villa or an apartment with a garden on terms rarely matched in Belgium. But the appeal goes well beyond the purchase price alone: property taxation in Spain and tax treaties play a decisive role in the overall financial equation.

Understanding the basics of property taxation in Spain
When a Belgian buys property in Spain, they must take into account several property purchase taxes, notably VAT, ITP (Impuesto sobre Transmisiones Patrimoniales) for resale properties, and AJD (Actos Jurídicos Documentados). These levies vary depending on the type of property (new build or resale) and the specific region where it is located. It is always useful to read our detailed guide to buying costs for a property transaction on the Costa Blanca.
After the purchase, the property tax in Spain (IBI), maintenance costs and non-resident income tax (IRNR) must be factored into the overall budget. Each of these items directly affects the return on your investment.
What does non-resident taxation cover?
For Belgian nationals who own property but are not tax residents in Spain, the non-resident tax regime applies. IRNR covers both the rental income generated in Spain and personal use of the property, even when it is not actually rented out.
For a property that is not rented out, IRNR is charged on imputed income equal to 2% of the cadastral value (1.1% if the municipality’s cadastral values were revised in the last 10 years), taxed at 19% for an EU/EEA resident such as a Belgian. For a rented property, the tax is charged on the rent: 19% for an EU/EEA resident, who may deduct expenses directly linked to the rental. The return is filed annually on Modelo 210. Double taxation is then dealt with under the bilateral agreements between Belgium and Spain (see below).
The special case of tax residence in Spain
Becoming a tax resident in Spain changes everything. Anyone who spends more than 183 days a year there or has their centre of economic interests in Spain automatically falls under Spanish tax residence. This means tax on worldwide income applies, but some newcomers who move to Spain to work can benefit from a special regime.
The Beckham regime (impatriate regime) is for people who move to Spain to work (employees, remote workers, company directors, entrepreneurs of innovative activities, highly qualified professionals) and who were not Spanish tax residents in the previous 5 years: their Spanish-source employment income is taxed at 24% up to €600,000 (47% above), for the year of arrival and the following 5 years. These tax advantages for expatriates are not available to retirees or passive investors. If you would like to know more about how to get in touch with our experts, we are at your disposal.
International tax treaties and avoiding double taxation
The existence of a bilateral tax treaty between Belgium and Spain protects buyers from excessive taxation. It sets the rules for determining where, when and how different types of income and property are taxed in order to avoid double taxation, a major source of confusion for many expatriates.
In practice, Spain taxes the property and Belgium exempts that income with progression: it is not taxed a second time, but it raises the rate applied to your other Belgian income. The IRNR paid in Spain is not credited against Belgian tax. Since tax year 2022 (income 2021), a Belgian cadastral income is set for the foreign property, which must be reported to the FPS Finance within 4 months of purchase. Declaring foreign income therefore remains essential, in line with the requirements of each tax authority.
Focus on taxation on resale and capital gains on property in Spain
When you sell a Spanish property, you will have to pay capital gains tax on the property, which applies to the profit made. The calculation is based on the difference between the purchase and sale price, adjusted for eligible investments, depreciation and costs. For a non-resident the rate is 19%, and the buyer withholds 3% of the sale price (Modelo 211) as a payment on account of this tax.
There are, however, relief mechanisms to reduce this burden, notably for senior owners or those reinvesting in a main residence. Hence the importance of getting advice from the time of purchase so that you can plan wisely for the tax implications of a future sale of the property.
Optimising your taxes: the importance of expert support in your language
Navigating Spanish and Belgian regulations with peace of mind means surrounding yourself with experts who speak your language and know the regulations of both countries inside out. A good adviser knows the subtleties of tax when buying a house in Spain, can spot the risk of filing errors and implements the best strategies to take full advantage of international tax treaties.
Dedicated support is sometimes the best investment to ensure your procedures are compliant, optimise your declaration of foreign income and, above all, identify exemptions or tax credits that would otherwise go unnoticed. For a personalised estimate of your future tax regime, consult a tax adviser; our expertise lies in supporting your purchase, from the property search to the practical paperwork (NIE, power of attorney).
Practical tips for mastering Spanish property taxation
Before buying, check your tax status carefully and plan your stays so that you do not risk becoming a tax resident inadvertently. Compare taxation in Belgium and in Spain, choose the most efficient purchase structure (in your own name or through a company) and always consult a recognised professional to secure the transaction.
Do not forget to budget for property purchase taxes such as VAT, ITP and AJD, which differ between the Valencian and Murcian provinces. Pay attention to the calendar of local declarations (IBI, IRNR), as omissions or delays can lead to penalties that are sometimes high.
Quick comparison: tax charges for non-residents vs Spanish tax residents
Below is a summary table showing the main differences in taxation depending on your status:
| Type of tax | Non-resident for tax purposes | Spanish tax resident |
|---|---|---|
| Property tax (IBI) | Mandatory | Mandatory |
| Tax on rental income | IRNR: 19% with deductible expenses for EU/EEA residents (including Belgium); 24% on the gross rent, with no deductions, for others | Progressive IRPF rates |
| Capital gains tax | 19% (3% of the price withheld by the buyer as a payment on account) | Possible relief (reinvestment, retirement, family transfer) |
| Declaration of worldwide income | No (Spanish income only) | Yes, all income worldwide |
This overview clearly shows the potential for tax optimisation when your personal situation changes or when structuring your property investments.
Frequently asked questions about property taxation for Belgians in Spain
How can you avoid double taxation when buying a house in Spain?
Thanks to the Belgian-Spanish tax treaty, your Spanish property income is taxed in Spain and exempt in Belgium with progression (there is no tax credit for the IRNR paid). The property must also be reported to the FPS Finance within 4 months of purchase. You still need to complete the declaration of foreign income correctly with both countries to ensure you are not taxed twice. A professional who speaks your language can help you organise these essential administrative procedures.
What are the main taxes paid by Belgian buyers in Spain?
When buying, budget for:
- VAT (10% on new builds)
- ITP on resale properties: 9% in the Valencian Community (deeds from 1 June 2026), 7.75% in the Region of Murcia (reduced rates under conditions for a main home)
- AJD on new builds: 1.4% in the Valencian Community (from 1 June 2026), 1.5% in the Region of Murcia (no proportional AJD on a resale subject to ITP)
After that, property tax (IBI), IRNR (if non-resident) and possibly capital gains tax on resale apply. Additional local charges may exist depending on the municipality or the autonomous community.
How can you optimise the taxation of your Spanish property investment?
Appropriate planning can reduce the tax impact:
- adapt the legal structure (purchase in your own name or through a structure)
- check the deductions linked to the use of the property (for example rental expenses for an EU/EEA resident)
- plan ahead for the capital gain and adjust the holding period
- get help from a specialist tax adviser who speaks your language
Regular follow-up also lets you benefit from new legislation introduced on the Costa Blanca or at national level.
Why use an expert who speaks your language to buy in Spain?

Their support provides reassurance on legal certainty and the compliance of your declarations, and makes the most of international tax treaties to minimise your overall tax burden.
