Passing on Wealth Tax-Free: Making the Most of Surplus Income

With frozen IHT thresholds and rising asset values, more estates are edging into taxable territory. A useful starting point is to look at whether your estate is increasing each year. If it is, this may be a sign that unused income is quietly accumulating and turning into capital — and once it becomes capital, it risks forming part of your taxable estate.

One of the most effective ways to avoid this “crystallisation” and reduce your estate during lifetime is the exemption for regular gifts made from surplus income.

Using income you have already paid tax on

If your income comfortably exceeds your day-to-day expenditure, the excess often sits untouched in your account. This is income that you have already paid income tax on, so passing some of it on can be a very efficient way to support family while reducing your future IHT liability.

There is no maximum limit to what you can give under this rule, and gifts that qualify are immediately exempt from IHT — there is no need to survive seven years.

Creating a clear pattern of gifting

To rely on the exemption, the payments must follow a recognisable pattern. HMRC usually looks for consistency in both the timing and the general value of the gifts.

A standing order, annual transfer, or a written note explaining the intention to make regular gifts can provide helpful evidence, especially if the donor dies before the pattern becomes long established.

The key is regularity and predictability — it should look like part of someone’s usual financial arrangements rather than an isolated or ad hoc payment.

Income must remain income

To qualify, the gift must come from genuine income received in that tax year — such as salary, pension income, rental income, dividends, or interest. Withdrawals from savings or investments will not meet the criteria.

It is also important that you can maintain your normal standard of living without dipping into capital. If your income stops covering your spending, HMRC may argue that the gift did not truly come from surplus income.

Keeping simple annual records of income and outgoings can make this easy to demonstrate later on.

A valuable but underused relief

Despite its potential, this rule is not widely used, often because individuals are unaware of it or assume it will be administratively difficult. In practice, once the pattern is set and the paperwork maintained, the exemption can be a straightforward and highly effective part of an estate planning strategy.

For clients with consistent income and a wish to support family during their lifetime, this relief can reduce the estate significantly over time while allowing loved ones to benefit when it matters most.
