Can I cut my potential tax bills when returning to UK?

18 August 2022

British by birth, I moved to the US 25 years ago for work reasons and now plan to move back with my family — my American wife and our two children. I understand there are special tax rules for returning domiciled people. What do I need to be aware of and should I transfer any assets into my wife’s name to reduce my potential tax liabilities?

If you were born in the UK and have a UK domicile of origin, the tax rules for ‘formerly domiciled residents’ (FDRs) will apply. Spouses without a common domicile are treated very differently for tax purposes by the UK.

Whilst FDRs are deemed domiciled whenever they are UK resident (subject to a one-year grace period for inheritance tax (IHT) purposes), non-FDRs are only deemed domiciled once they have been UK resident for at least 15 of the preceding 20 tax years. The FDR rules now cover income tax and capital gains tax (CGT).

That said, for income tax and CGT purposes, exposure to UK tax will still largely be assessed under the Statutory Residence Test — which assesses a person’s status related to the number of days they spend in the UK — not domicile test. However, an FDR will be deemed UK domicile for income tax and CGT purposes as soon as they become UK resident. The most significant consequence of this is that an FDR will not be able to benefit from the remittance basis of taxation while resident in the UK, under which tax on foreign earnings and gains is paid only if the funds are transferred to the UK.

For IHT, a formerly domiciled individual will be deemed UK domicile from the start of their second tax year of continuous UK residence. From that point, their worldwide estate would be subject to IHT while they remain UK tax resident, and possibly for a short period afterwards.

In terms of planning while you are still overseas, you should be aware that trusts set up by FDRs who become deemed domiciled under the FDR rule are taxed on the arising basis on foreign income and gains within their offshore trusts (in line with the taxation of trusts settled by an actual UK domicile).

In contrast, your non-FDR spouse could establish an offshore trust and later become deemed domiciled under the 15-year rule but still benefit from a form of tax-protected offshore trust. This type of trust will prevent the non-UK assets from being subject to IHT. As the US Estate Tax threshold is considerably more generous than the UK, this may result in a significant tax saving, although tax advice should be sought before the transfer of any assets.

This protected status will, however, be lost if your wife acquires an actual UK domicile or if the trust falls foul of the rules at any time.
