If you are non-resident for Income Tax and Capital Gains, that means you’re non-resident for the other taxes right? Of course not – that would be too simple. This is tax we’re talking about!
Our tax system has built up over time with residency definitions developing independently based on historical contexts, legal precedents, and changing economic conditions.
Due to the different definitions, an individual could (in theory) be non-UK resident for Income Tax, Capital Gains Tax, and Stamp Duty Land Tax, but UK resident for VAT, National Insurance, Withholding Tax and the Non-Resident Landlord Scheme. And they might also be domiciled in the UK for Inheritance Tax purposes.
Some of the definitions of tax residency are below:
𝗜𝗻𝗰𝗼𝗺𝗲 𝗧𝗮𝘅 𝗮𝗻𝗱 𝗖𝗮𝗽𝗶𝘁𝗮𝗹 𝗚𝗮𝗶𝗻𝘀 𝗧𝗮𝘅 – this goes by the Statutory Residency test, which has Automatic Overseas tests, Automatic UK tests, and a Sufficient Ties test. Note that the UK test can be overridden by a Double Tax Treaty, meaning you can be UK resident under domestic law but non-resident by virtue of a Treaty.
𝗡𝗮𝘁𝗶𝗼𝗻𝗮𝗹 𝗜𝗻𝘀𝘂𝗿𝗮𝗻𝗰𝗲 𝗖𝗼𝗻𝘁𝗿𝗶𝗯𝘂𝘁𝗶𝗼𝗻𝘀 – non-residency is where you are ‘ordinarily resident’ outside the UK. This is not defined in the legislation but there is case law which assists in interpreting the definition. Your residency is where you have a settled and regular mode of life, and where you live apart from temporary/occasional absences. Although the need to use this definition can be overridden by Bilateral Social Security Agreements.
𝗦𝘁𝗮𝗺𝗽 𝗗𝘂𝘁𝘆 𝗟𝗮𝗻𝗱 𝗧𝗮𝘅 – non-residency occurs when you spend fewer than 183 days in the UK in any continuous period of 365 days beginning 364 days before and ending 365 days after the transaction occurs.
𝗪𝗶𝘁𝗵𝗵𝗼𝗹𝗱𝗶𝗻𝗴 𝗧𝗮𝘅 𝗮𝗻𝗱 𝘁𝗵𝗲 𝗡𝗼𝗻-𝗥𝗲𝘀𝗶𝗱𝗲𝗻𝘁 𝗟𝗮𝗻𝗱𝗹𝗼𝗿𝗱 𝗦𝗰𝗵𝗲𝗺𝗲 – you are non-resident if your ‘usual place of abode’ is outside the UK.
𝗜𝗻𝗵𝗲𝗿𝗶𝘁𝗮𝗻𝗰𝗲 𝗧𝗮𝘅 – this is not actually based on residency (currently) but on a closely linked concept called ‘domicile’. Massively simplifying, you can be non-UK domicile and therefore not subject to Inheritance Tax where you have a ‘voluntary residence as an inhabitant’ overseas and a ‘settled intention to permanently reside’ there.
𝗩𝗔𝗧 – you are non-resident if your ‘usual place of residence’ is overseas. Again, this is not defined in legislation but there is a raft of case law to assist.
Do we really need all these separate definitions? This could have been something for the Office of Tax Simplification to look at, if it hadn’t been abolished back in 2022.
