The employer's side is already very complicated though. International banking is not settled. You cannot settle your taxes in Spain with a foreign IBAN, there are similar issues with many other services too (internet, phone and utility contracts, etc.). I didn't mention income taxes, but payroll taxes i.e. the employer side. But income tax shouldn't exist anyway. > Insurance isn't needed. You can insure yourself in your new country. But the employer is usually required to pay it - e.g. national insurance in the UK, social security in Spain, that is a massive barrier to international work even within the EU. There needs to be agreements to split the payment to allow the employer and the employee to reside and operate in different EU member countries. > Oh, I see. You're only in it for the money. Making business easier makes us all more money (less friction and overhead = a bigger pie). I'm not even a business owner, but could benefit a lot if I could more easily move somewhere within the EU with a lower cost of living.
