Non-domiciled' residents
The same rules apply if you make any foreign capital gains, eg you sell shares or a second home.
Working out your domicile
Your domicile’s usually the country your father considered his permanent home when you were born. It may have changed if you moved abroad and you don’t intend to return.
There are additional rules for domicile and Inheritance Tax
The rate of Inheritance Tax is 40% on anything above the threshold. The rate may be reduced to 36% if 10% or more of the estate is left to charity.
Tax if you’re non-domiciled
You don’t pay UK tax on your foreign income or gains if both:
they’re less than £2,000 in the tax year
you don’t bring them into the UK, eg transfer them to a UK bank account
If this applies to you, you don’t need to do anything.
If your income is £2,000 or more
You must report foreign income or gains of £2,000 or more, or any money that you bring to the UK, in a Self Assessment tax return.
If you work in the UK and abroad
There are special rules if you work both in the UK and abroad.
You don’t have to pay tax on foreign income or gains (even those you bring into the UK) if you get the ‘foreign workers’ exemption’.
your income from your overseas job is less than £10,000
your other foreign income (eg bank interest) is less than £100
all your foreign income has been subject to foreign tax (even if you didn’t have to pay, eg because of a tax-free allowance)
