Who Can Actually Use This Arrangement?
You need to tick specific boxes to qualify. First, you must be a UK resident for tax purposes, which usually means spending enough time here that HMRC considers this your home.
But here's the twist: you also need to be "not domiciled" in the UK. Domicile is different from residence or nationality it's essentially where you consider your permanent home to be.
Most people inherit their domicile from their father when they're born. You can have British citizenship but not be domiciled here, which is what opens the door to claiming remittance basis.
If your unremitted foreign income and gains are under £2,000 in a tax year, you automatically get remittance basis treatment. No claim needed, no charges to pay.
Once you've lived in the UK for a while, things get pricier. Been here for seven of the last nine years? You'll face an annual charge if you want to keep using this arrangement.
That charge starts at £30,000 a year. After twelve years of UK residence in any fourteen-year period, it jumps to £60,000 annually.
Your nationality doesn't matter for these rules. Someone from France, Australia, or anywhere else can potentially use the remittance basis if their domicile is outside the UK.
