Belgian buyers have to declare an Ibiza villa at home, and will almost never pay Belgian income tax on it. The Spain-Belgium treaty leaves the property’s income and gains to Spain, and Belgium exempts them, counting the income only to set the rate on your other earnings. The real Belgian cost comes at the end: regional inheritance tax on a Belgian resident’s worldwide estate. Belgians made 3.69% of all foreign home purchases in Spain in the second quarter of 2026. This guide is for Belgian buyers of prime homes on Ibiza.

What does Spain charge a Belgian owner?
The same as any EU owner, and the table below sets the rates out. Belgium has no wealth tax on property, so the charge that will feel new is Spain’s: the Balearics levy it in full on Spanish assets above EUR 700,000. The Spanish income taxes on the villa are, in practice, the only income tax you’ll pay on it, because Belgium exempts that income. Our Ibiza property tax guide runs the numbers.
| Spanish tax for a Belgian owner (2026) | Rate |
|---|---|
| Transfer tax on a resale | 8% to 13% in Balearic bands: EUR 600,000 on EUR 5M |
| New build | 10% VAT plus 2% stamp duty from EUR 1M |
| Home kept for own use | 19% of a notional 1.1% of cadastral value |
| Rental income | 19% of the net rent |
| Gain on sale | 19%, with 3% of the price withheld by the buyer |
| Wealth tax | Spanish assets above EUR 700,000: about EUR 53,500 a year on EUR 5M |
What does Belgium tax on the villa?
Nothing directly, but it still has to be declared. Under the Spain-Belgium tax treaty, income from Spanish property is taxed in Spain and exempt in Belgium. The exemption comes with progression: the Spanish income is added back only to work out the rate Belgium charges on your other Belgian income, such as a salary or pension. So the villa can nudge up the rate on your Belgian earnings without being taxed in Belgium itself.
How Belgium measures that income changed on 17 February 2021, in your favour. Belgium used to count foreign property at its actual or estimated rental value, a rule the European Court of Justice found discriminatory. Now the Belgian tax authority assigns a foreign home a cadastral income on the same basis as a Belgian one, which is usually a much lower figure. Declare the Spanish home on your Belgian return so that it can be assessed.
| Tax on the Ibiza home | Spain | Belgium (if Belgian-resident) |
|---|---|---|
| Income from the home | 19% of notional income or net rent | Exempt, counted for the rate on other income |
| Gain on sale | 19% | Exempt under the treaty |
| Wealth tax | Above EUR 700,000 | None on property |
| Inheritance, close family | 100% Balearic relief | Regional inheritance tax on a resident’s worldwide estate |
Will Belgium tax you when you sell?
Usually not. The treaty gives the gain on Spanish property to Spain, which taxes it at 19%, and Belgium exempts it. So the Spanish tax is the whole tax on the gain, not a first instalment before a Belgian top-up.
Two Belgian rules are worth knowing so they don’t cause worry. Belgium taxes a private individual’s gain on a second home sold within five years of purchase, at 16.5%, but most buyers of prime villas hold far longer. And the new Belgian capital gains tax that took effect on 1 January 2026 covers financial assets such as shares and funds, at 10% above a EUR 10,000 annual allowance. It does not apply to real estate, so your Ibiza villa sits outside it.
How does inheritance work for a Belgian family?
Spain largely steps aside; Belgium doesn’t. A Belgian family’s children, grandchildren, spouse and parents have been fully relieved of Balearic inheritance tax since July 2023, and the relief works even though the person who died lived in Belgium. But Belgium’s regional inheritance taxes, set by Flanders, Wallonia or Brussels depending on where the deceased lived, apply to a Belgian resident’s worldwide estate, including the villa.
Belgium gives credit for foreign inheritance tax on foreign property, but with the Balearic relief there is little or none to credit, so the Belgian regional rate applies. Which law governs the estate is set by the EU Succession Regulation: Belgian law for a Belgian resident, unless the will picks the law of another nationality you hold. Plan ownership and gifts with Belgian and Spanish advisers before you buy, not after.
Can you move to Ibiza?
Yes, freely. As an EU citizen you need no visa and register as a resident after three months. The end of Spain’s golden visa in April 2025 makes no difference to you.
Living there most of the year is another matter. Pass 183 days in a year, or shift your business life to Spain, and Spain taxes you as a resident, on income and wealth worldwide, with a Balearic wealth-tax allowance of EUR 3M. Our residency guide explains the switch.
What should a Belgian buyer check?
On the Belgian side, that the villa is declared and assessed, and how the progression effect will touch your Belgian income. On the island, check that a country house and its pool are fully licensed, how it gets its water, and, if letting is the plan, that it already holds a tourist registration: a rustic-land home built after 1956 can’t get one since August 2025.
The order of the purchase is in our buying guide; for where to look, see our prime areas guide, and for the market as a whole, our main Ibiza guide.
Key takeaways
- Spain taxes a Belgian owner at EU rates: 19% on net rent, notional income and gains.
- Belgium exempts the Spanish income but counts it for the rate on your other income.
- Since 2021, Belgium values foreign homes on a cadastral income, usually lower than the old rental value.
- The gain on sale is taxed in Spain only; the 2026 Belgian capital gains tax doesn’t cover property.
- Belgian regional inheritance tax still reaches the villa, even though Spain gives close family 100% relief.
- Budget for Spanish wealth tax, which Belgium doesn’t have: about EUR 53,500 a year on EUR 5M.
Frequently asked questions
Can Belgians buy property in Ibiza freely?
Yes. EU citizens face no restrictions. Get a Spanish tax number (NIE) and a lawyer who acts only for you.
Do I have to declare an Ibiza villa in Belgium?
Yes. A Belgian resident declares foreign property on their Belgian return, even though its income is exempt under the treaty.
Is income from a Spanish property taxed in Belgium?
No. It is taxed in Spain and exempt in Belgium, but Belgium counts it to set the rate on your other Belgian income.
How does Belgium value a foreign home?
Since 17 February 2021, on a cadastral income assigned by the Belgian tax authority, on the same basis as a Belgian property, instead of its rental value.
Does Belgium tax the gain when I sell my Ibiza villa?
No. The treaty gives the gain to Spain, which taxes it at 19%, and Belgium exempts it.
Does the 2026 Belgian capital gains tax apply to property abroad?
No. It covers financial assets such as shares and funds, not real estate.
Do Belgian owners pay Spanish wealth tax?
Yes. The Balearics charge it in full above an allowance of EUR 700,000, so a Belgian owner with EUR 5M of net Spanish assets pays about EUR 53,500 a year.
Does Belgian inheritance tax apply to a villa in Ibiza?
Yes, for a Belgian resident’s estate. The Balearic relief removes the Spanish tax for close family, so there is little Spanish tax to credit against the Belgian regional tax.

No. Belgians, like all EU citizens, can live in Spain by right and register after three months.
When does a Belgian owner become Spanish tax-resident?
