Thanks. Is it not possible to stay under PAYE system in the UK and only declare this foreign income? What sort of evidence do I need to send them?
Sorry, I am not quite sure, whether I would need to work it all out from scratch or is it enough to copy what Inland Revenue had already calculated as my tax? (For example this year I am supposed to have underpaid, because that got my tax free allowance wrong). Also what would constitute "expenses" during my weeks in Spain?
Thanks. Can you tell me what sort of proof do I need to provide to show that the Spanish tax had been paid at source?
Yes but so far they just told me things by emails (like: "if they ask, tell them it's deducted at source"). What do they need to provide?
