I am currently a full-time employee at a UK registered charity currently residing in the UK. I have verbal approval from the organisation to work abroad under Spain's new digital nomad visa programme. Under the visa programme I would be registered as working in the UK for my current organisation. I would, from what I understand, remain PAYE but apply for a UK tax exemption under the dual taxation agreement - waiving taxation at source and instead filing my taxes in Spain.
My organisation is concerned over the additional administrative burden of having an employee residing in a foreign country. If I am remaining PAYE and simply changing my personal tax code to allow me to file taxes in Spain as a resident, what impact will this have on my charities annual tax fillings and will this create a significant additional administrative burden for the organisation?
I understand this is a broad question, but would appreciate any infromation you can provide.
