This principle applies to clients who have no or minimal earnings, such as those who only have state pension or are in full time education. University students (those over the age of 18) with no earnings whatsoever, can make a chargeable gain of £17,570 on an offshore bond without incurring any tax.
Note also that if the PSA is included, that figure is actually £18,570. From 6 April 2016, the £1,000 PSA was introduced. If however any of the individual’s income is higher rate income, then the allowance will be reduced to £500. If any of the income is additional rate income, then the allowance will be nil. The PSA is more accurately described as a savings nil rate, since the amount of savings income covered by the PSA will still form part of the individual’s total income.
