If I (who live in the EU but outside the UK) come and do a contract in the UK, then I will be liable for UK income tax on the income from that contract, but not NIC (if I have an E101 from my country of residence).
Question: how do we work out the sum on which the UK Income Tax is due? It shouldn't be the whole amount because that would take no account of NI or equivalent payments. Would it be the taxable income of a UK resident in the same contrat? Or the equivalent taxable income in my country of residence?
