These three cases illustrate how the same rules play out differently.
Case 1 – Tech employee based in Spain with a German employer
She moved to Valencia during the pandemic and never updated her situation. In 2025, HR asks for clarity: either she transfers her contract to a Spanish entity or comes back regularly to Germany. Spain may claim income tax and social contributions because she performs most of her work there. The solution is to align her contract and tax residence with Spain, possibly using the Spanish digital-nomad visa if she meets the conditions.
Case 2 – Freelance consultant living in France with UK and US clients
He invoices foreign companies from his home office in Lyon. If he spends most of the year in France, French tax rules and social contributions apply, even if all clients are abroad. Depending on how he structures his business, there can also be a risk that authorities see a permanent establishment abroad. Our guides on banking and invoicing for expats can help him organise his accounts, starting with Best Banks for Expats in Europe 2025.
Case 3 – Compliant digital nomad in Greece under a specific visa
She lives in Athens under an official digital-nomad visa, works for a foreign employer and pays tax in Greece. Her social security and immigration status are clear, and she keeps documents proving her days in and out of the country. She still travels, but always from a solid legal home base.
