Non-UK domiciled partners are subject to UK tax on their allocation of profits arising in the UK but are only taxable in the UK on their overseas profits which are remitted. If the partner has an overseas account which receives both elements of his profit share HMRC's practice in the years up to 5 April 2008 was to accept that the UK profits were treated as being remitted to the UK first, with any balance of the total remittances relating to overseas profits. This is best explained by way of an example:
- Example 1 – HMRC Practice up to 5 April 2008
UK profit share - £40,000
Remittance to the UK - £50,000
Taxable on £40,000 of UK income
Taxable on £10,000 of overseas income
Total UK taxable income £50,000
The changes to the taxation of non-UK domiciled individuals introduced new rules for remittances from "mixed accounts". A "mixed account" is an overseas account which has a mixture of sources of income and gains and would include a partner's account which has a mixture of UK and non-UK source income, as described above. The new legislation sets out rules for taxing remittances from a mixed account. These rules override previous HMRC practice with effect from 6 April 2008.
Under the new rules, where a remittance is made to the UK from a mixed account, the foreign income will be taxed before UK source income. This could have the effect of significantly increasing a partner's UK tax liability. Using the same figures this is shown in example 2.
- Example 2 – Taxation of a mixed account from 6 April 2008
UK profit share - £40,000
Remittance to the UK - £50,000
Taxable on £40,000 of UK income on an arising basis
Taxable on £50,000 of overseas income based on remittances to the UK
Total UK taxable income £90,000
This issue will only arise where the UK and overseas profits are paid into a mixed account and a subsequent remittance is made from that account. The effect is that the UK tax liability for a non-UK domiciled partner may increase significantly from 6 April 2008 unless steps are taken to counter this.
In either example, if any tax has been paid overseas in relation to the overseas profits, it may be possible to claim a tax credit against the UK tax due.
We understand that the new rules were not intended to have these consequences so it is possible that guidance will be given by HMRC to reinstate the former position. However, until then, non-UK domiciled partners should consider changing their banking arrangements so that this unintended and unwelcome tax increase does not arise.
