Who is this article for?

Advisers wanting to find out about the income tax treatment of trusts created by a UK individual, when their unmarried minor children are beneficiaries of the trust.

Key takeaways

Introduction

The benefits of a bare trust can be summarised as:

  • certainty over who can benefit
  • efficient Inheritance Tax (IHT) treatment of the initial gift – a Potentially Exempt Transfer
  • No ongoing IHT charges on the trust
  • for Income Tax and Captial Gains Tax purposes the trust is transparent, with the liability falling on the beneficiary (or beneficiaries) at their own rates of tax and with access to their own personal allowances and reliefs

 The last benefit above is restricted though by an anti avoidance rule known as the ‘Parental Settlement Rules’.

 

Parental settlements

One area often overlooked is the source of the money in relation to income tax. Where assets are placed under trust from parents for minor unmarried children, if gross income exceeds £100 per annum all of the income will be taxed as if it was the parents’. This is per parent (settlor), per child. For collective investments (unit trusts and OEICs), this applies to income that is distributed as well as income that is re-invested into accumulation units. Income below the £100 limit will continue to be assessed as the child’s income and taxed accordingly.

This has applied to bare trusts since 9 March 1999 and applies whether the income is paid to the child or not. For trusts created before this date which have not had any additional funds added, the £100 rule does not apply. Where the trust is a discretionary trust, the £100 rule will only apply where income is actually distributed from the trustees to the minor beneficiary.

Example

Paul puts £5,000 into a bare trust for his son John and invests in a high yielding bank account. After one year the bank account pays interest of £500 gross and the bank deducts 20% (£100) at source. Paul is a higher-rate taxpayer and John a non-taxpayer. Despite the capital being in trust for John, Paul has an additional 20% to pay, ie another £100. As the income is only being rolled up inside the bank account, holding a cash investment through another structure, may well avoid this tax complication. Once John reaches 18, he will be absolutely entitled to the capital and income and it will be taxed as his own.

If, in the above example, the interest is distributed to John when it arises, Paul will still be liable to income tax.

However, if Paul had invested in growth assets then the trustees would be able to utilise John’s own capital gains annual exempt amount, year on year, on any capital gain made inside the trust.

Using a bare trust provides a number of benefits covered above, but when used by parents of minor children this can remove some of the tax efficiency. There other options for saving for children though.
