Many accountants tend to avoid trying to give you advice on cross border tax issues, mainly because they aren't qualified to give you proper advice and it can be so complex that even the authorities don't understand it. So, you sometimes have to figure it out for yourself, and the best way to approach it is to look at how the authorities in each jurisdiction will see it from their perspective. If you work and pay Spanish taxes, I assume you have the right to work in Spain too (e.g. EU citizenship or spouse of an EU citizen). In countries with strong government health insurance, private insurance is often not that expensive.
