The position becomes more complicated when looking at UK resident, non-domiciled taxpayers who are subject to the remittance basis and subject to the £30,000 or £50,000 remittance basis charge.
If there is insufficient UK and nominated foreign income available to cover the available reliefs, a further amount of foreign income is deemed to be added to give a tax increase equal to the remittance basis charge. This is best illustrated by way of an example:
Jemima has UK income of:
£2,000,000
and is claiming reliefs subject to the restriction of:
£600,000
Jemima claims the remittance basis and pays the remittance basis levy:
£30,000
Based on her UK income, without the deemed addition, the reliefs would be restricted to:
£2,000,000 x 25% = £500,000
Her income subject to tax would be:
£1,500,000
As there are surplus reliefs available, it is necessary to add an amount of deemed income in order to ascertain the amount of reliefs that may be used, as follows:
Remittance basis charge £30,000 grossed up at marginal rate of tax:
£30,000 x 100/45 = £66,667
The amount of adjusted net income on which the restricted reliefs will be based is therefore:
£2,000,000 + £66,667 = £2,066,667
Jemima’s restricted reliefs are therefore:
£2,066,667 x 25% = £516,667
rather than £500,000.
