I am an EU national based in the UK working for a British company. I would like to live and work remotely from Spain between 3 to 6 months per year. My current company told me they would not accomodate that and other companies interested in hiring me won't accomodate it either, without providing details. I would like to understand what the tax/law implications are that make companies so reluctant.
I'm a senior software engineer with a skillset that attracts lots of recruiters and companies, but as soon as I mention my plan, they quickly either ignore me or tell me it won't be possible.
Based on my research, I would remain a tak UK resident as I would spend less than 183 days per year from Spain. My understanding is that companies need to pay PAYE tax based on how long I work from abroad (https://www.gov.uk/guidance/paying-employees-working-abroad), which involves filling a P85 form. From a NICs perspective, it looks like there are no special implications as long as this arrangement does not go beyond 2 years (https://www.gov.uk/guidance/national-insurance-for-workers-from-the-uk-working-in-the-eea-or-switzerland).
I acknowledge this is a fairly niche situation but any information or links to resources would be greatly appreciated. The more I search, the more contradictory statements I find, and I'm quickly overwhelmed by all the jargon.
