Hello, I’m dual nationality, UK and Portugal. I haven’t lived in the UK for years. I’ve just bought a property in wales that I’m going to rent out as a holiday let. Would I be able to claim the personal allowance in the UK against the income?
As you are a British citizen, you are entitled to claim the personal allowance no matter where in the world you live, or whether you hold dual citizenship. So yes, you can use the personal allowance against your UK rental income.
