Lately, many friends on the forum have been discussing tax matters, especially the dreaded wealth tax. When I first came to Spain, I thought I only had to worry about IBI (local property tax), but I later discovered this ’millionaire’s tax’ was also waiting for me. Seeing the lively discussion, I’ve compiled my recent findings to get the ball rolling. Hopefully, this can help some people, and I welcome corrections and additions from the experts here.
What is Wealth Tax?
Simply put, wealth tax is a tax levied on an individual’s net assets. If the value of all your assets in Spain, minus your liabilities, exceeds the tax-free allowance, you have to pay. This includes property, bank deposits, stocks, funds, luxury cars, and so on. For most of us, our most valuable asset is likely our home. That’s why when discussing Spain’s wealth tax, the conversation often turns to property, and this wealth tax is commonly known as the ‘property wealth tax’.
Thresholds and Rates by Autonomous Community
The most complicated part of this tax is that while there is a national basic law, each autonomous community has its own set of rules. The nationally established tax-free allowance is €700,000, with an additional €300,000 exemption for the primary residence. This means, in theory, you only need to start thinking about this tax if your net assets exceed €1 million. However! The autonomous communities can modify these allowances and rates themselves
! This leads to huge differences in tax burdens across Spain.

For example, Madrid and Andalusia previously offered a 100% tax relief, effectively making it tax-free. But starting in 2023, to promote ‘tax fairness,’ the central government introduced a ‘Solidarity Tax’ specifically targeting the wealthy in regions where the wealth tax is rebated. The threshold for this new tax is €3 million. So, if you are in Madrid or Andalusia and your assets are below €3 million, you generally don’t have to worry. But in places like Catalonia and Valencia, where the allowances are lower and the rates are higher, things are tougher.
Below is a simplified table I’ve put together to give you a quick overview of the differences in a few popular regions:
| Autonomous Community | General Allowance | Tax Rate | Notes |
| Community of Madrid | €700,000 | 100% relief | Solidarity Tax applies to net assets over €3 million |
| Andalusia | €700,000 | 100% relief | Same as above |
| Catalonia | €500,000 | 0.21% - 2.75% | One of the highest tax burden regions in Spain |
| Valencian Community | €500,000 | 0.25% - 3.5% | Higher primary residence allowance of €600,000 |
This tax doesn’t affect most ordinary working families, as it’s difficult to exceed the tax-free allowance. But if you own several properties in Barcelona or Valencia, or are planning a large investment, you should definitely consult a professional tax advisor (asesor fiscal)
in advance for planning. Don’t just assume things; getting investigated by the tax authorities can be a major headache. If anyone has good tax avoidance tips, feel free to share and discuss them in the comments below!
