The 10 year anniversary charge, sometimes called the principal or periodic charge, is an inheritance tax charge that applies to most trusts holding relevant property once every ten years. It is charged on the net value of the relevant property in the trust, up to a maximum of 6% of the value above the tax-free threshold (gov.uk, as at July 2026, subject to change).
Trusts sit in their own inheritance tax regime, so a discretionary trust can face charges during its life rather than only on death. This guide explains what the anniversary charge is, which trusts it affects, how it is calculated, the related exit charge when assets leave, and the reporting deadlines. It forms part of our wider guide to inheritance tax on trusts. Figures are current as at July 2026 and are subject to change.
What is the trust 10 year anniversary charge?
It is a periodic inheritance tax charge on the value held in a relevant property trust. Inheritance tax is charged at each 10-year anniversary of the date the trust was set up, on the net value of any relevant property in the trust on the day before that anniversary. The rate can reach a maximum of 6% of the value above the available threshold (gov.uk, trusts and inheritance tax, as at July 2026, subject to change).
Which trusts face the charge?
The charge applies to trusts holding what the rules call relevant property, which covers most discretionary trusts and many other trusts set up in a settlor's lifetime. Assets such as money, shares, land and buildings held in these trusts are generally relevant property, so they can be caught by both the anniversary charge and the exit charge (gov.uk, trusts and inheritance tax, as at July 2026, subject to change). Some trusts, such as certain bare trusts and some trusts for disabled or bereaved young people, are treated differently.
| Trust type | Relevant property regime? |
|---|---|
| Discretionary trust | Generally yes |
| Most lifetime trusts holding assets for a class of beneficiaries | Often yes |
| Bare trust (assets held for a named person absolutely) | Generally no |
| Some trusts for disabled or bereaved young people | Treated differently |
