If you want to stay in Spain for more than 183 days per calendar year, or if you want to work in Spain or start your own business, you are required to apply for a residence permit.
This means that you have to unsubscribe from the United Kingdom.
Unsubscribe does not automatically mean that you are no longer taxable in the Netherlands. You can choose to become a resident of Spain and still be taxable in the Netherlands.
