What is wealth tax and how does it affect residents and non-residents?

August 5, 2025

The wealth tax has been a recurring topic of debate in Spain. Its complexity generates many questions, especially among those with substantial wealth, whether residents or non-residents.

Unlike other taxes, this tax levies the entire net worth of an individual as of December 31 of each year, not just the income earned.

In this article, we explain everything you need to know about wealth tax, the differences between residents and non-residents, the new solidarity tax, and how it affects your wealth planning.

The wealth tax: basic concepts

This tax is direct, personal, and supplementary to personal income tax (IRPF). The taxable base consists of all assets and rights of economic value belonging to a person, valued according to the relevant regulations. Debts and encumbrances related to these assets are then deducted from this sum.

What assets and rights are included?

  • Real estate (houses, premises, land).
  • Bank deposits, current accounts and financial products.
  • Stocks, bonds and securities.
  • Life insurance.
  • Art objects, antiques and jewelry.
  • Vehicles and boats.

Exemptions and exempt minimums

There are significant exemptions, such as for primary residences (up to €300,000) and family businesses. In addition, there is a general tax-free allowance of €700,000 at the national level.

The situation of residents in Spain

If you are a tax resident in Spain, you are taxed on all your assets, whether they are inside or outside the country.

Furthermore, the administration of wealth tax is delegated to the autonomous communities. Each one can modify the tax-free threshold, the tax rate, and apply tax breaks.

Madrid and Andalusia: special cases

Until recently, regions like Madrid and Andalusia offered a 100% tax break, which in practice meant paying no tax at all. This attracted wealthy individuals to these regions.

Other autonomous communities

In other regions such as Catalonia, Valencia, the Balearic Islands or Extremadura, the wealth tax is effectively applied and can represent a significant burden.

The case of non-residents

If you are not a tax resident in Spain, you only pay taxes on the assets and rights you own within Spanish territory. Your overall net worth is not taken into account.

Real estate and other assets

The main reason a non-resident must declare this tax is the ownership of real estate in Spain. Bank accounts and shares in Spanish companies are also included.

Application of regional regulations

Thanks to a ruling by the Court of Justice of the European Union, if you reside in an EU or EEA country, you can apply the regulations of the autonomous community where you hold the majority of your assets. This may entitle you to tax breaks. If you reside outside the EU/EEA, national regulations apply.

The temporary solidarity tax on large fortunes

Since 2023, a new tax has been in place: the wealth solidarity tax (ITSGF). Its aim is to ensure that large fortunes are taxed in all regions, even where a wealth tax reduction applies.

Who does it affect?

This tax applies to residents and non-residents with a net worth exceeding 3 million euros.

How does it work?

A progressive scale is applied starting from €3,000,000. From the resulting amount, any wealth tax already paid is deducted, thus avoiding double taxation.

Estate planning: key to optimization

The combination of wealth tax and ITSGF makes advance planning essential.

Asset valuation

How you value your assets (especially real estate and stocks) directly affects your taxable income. It is essential to carry out realistic and accurate valuations.

Investment structures

In certain cases, structuring your investment through companies or funds can offer tax advantages. However, it should always be done with legal advice to avoid risks.

Professional advice

In a complex and ever-changing tax environment, having a specialized team is key. A tax advisor can help you understand which regulations apply to you, how to file your taxes correctly, and how to optimize your situation.
