Self Assessment: UK tax guides
You must still file a UK Self Assessment tax return from abroad if you have UK income or gains, or if HMRC has issued you a notice to file, even though you are non-resident. The 3 guides in this section cover Expat Self Assessment, Why You Cannot File the SA109 on HMRC Online and Let Property Campaign.
