Hello everyone,
I wonder if anyone could share their experience or advice regarding moving to Barcelona while maintaining relation with current British employer.
I have done quite broad research online and read multiple sources but I feel like they contradict each other.

I have European passport so relocation for me shouldn’t be a problem and I understand more or less what needs to be done for my wife, who doesn’t have European passport, to stay legally on Spain.

However I’m not exactly sure about best work solutions. My company doesn’t have a Spanish branch and I would be the first employee to work overseas. To my understanding, UK tax system should not be a problem as all I have to do is to feel a form to notify of work overseas to avoid double taxation.

What I’m not sure of is how Spanish side works. I heard lots about employer having to pay Spanish social security for me. Does it require the company to have a legal presence in Spain? What other issues does staying on British payroll cause? Anyone is such situation?

The two other solutions I learnt about is either registering myself as ‘autonomo’. But that brings potential “falso autonomo” issue as I would like to work for the same company or using EOR. Not sure what drawbacks using EoR has beside having to sacrifice some salary to pay for their services. But how does EoR solve “falso autonomo” issue?

I’m aware of Digital Nomad but afaik it’s limited to 3 years and ideally we would like to move indefinitely.

Thanks,
Jan
