Wealth tax was temporarily re-established for the periods of 2011, 2012, due to the financial crisis.
This case has been extended year after year, and is currently still in force.
As a non-resident, you’re obliged to present this kind of tax yearly, if your property or assets in Spain surpass 700.000€
Imagine that your property has a value of 1.000.000€, but it’s + owned in equal marital parts. Seen as the figure of 500.000€ per person isn’t surpassed, you wouldn’t have the obligation of presenting this kind of tax.
