Common challenges for Spain-based freelancers

These are the issues we see most often from freelancers in Spain.

1

Does Spain tax your foreign income?

Most countries tax residents on worldwide income. If you’re earning from foreign clients while based in Spain, you likely need to declare that income to your local tax authority.

2

Double taxation risk is real

Without understanding the tax treaty between Spain and your client’s country, you could end up paying tax on the same income in both places.

3

Local accountants don’t know foreign rules

Your accountant in Spain knows local tax law. But cross-border work requires understanding both countries’ rules and how they interact through treaties.

Key tax facts for Spain
