Hello,
I am a Spanish citizen with settlement status living in the UK. I am planning to return to Spain shortly and my company is considering whether it is possible to keep me employed remotely. I undertand that I would personally need to fill out the P85 form and declare my salary in Spain. However, my company would like to know if there is specific guidance for them or if so, to confirm that there are no specific actions they need to take on their part to do this.
Thank you
