Assigning a bond: when it triggers a chargeable event (and when it doesn’t)
A gift assignment moves the bond with no tax now; an assignment for value is a chargeable event. And once trustees hold the bond, the gain is taxed at the trust rate with no top-slicing relief.
Based on ITTOIA 2005 ss.484, 465–467 and HMRC’s Insurance Policyholder Taxation Manual (IPTM7360, IPTM3250).

Assigning a bond — moving its legal ownership — sometimes triggers a tax charge and sometimes doesn't, and the line is whether it was done for money or money's worth. The same act can be a chargeable event or a tax-neutral transfer depending on the consideration, and once a trust holds the bond, who is taxed (and whether top-slicing relief survives) changes again.
The rule
A whole assignment of a bond for money or money's worthis a chargeable event (ITTOIA 2005 s.484; IPTM7360) — and “money's worth” is wider than cash: a transfer in exchange for a valuable asset counts. A whole assignment notfor money's worth — a gift — is nota chargeable event, and a part assignment by way of gift (for insurance years from 6 April 2001) cannot be a chargeable event or an excess event either. A gift assignment doesn't wipe the slate clean, though: the new owner takes the policy at its existing base cost and inherits the entire premium and withdrawal history, so the whole gain — including the growth before the gift — falls on them when they eventually surrender.
Trustees change who is taxed
Holding a bond in trust doesn't avoid the gain; it relocates it. Where UK trustees of a discretionary (non-bare) trust are the persons liable, the gain is taxed at the trust rate and there is no top-slicing relief — the relief is given only to individuals (ITTOIA 2005 ss.465–467; IPTM3250). A bare trust is different: the beneficiary is treated as the individual liable and can claim relief on their own position. So assigning a bond out of a discretionary trust to an individual beneficiary before the surrender can change both the rate and the availability of relief. The full eligibility map is in Can trustees claim top-slicing relief?
- Assignment by gift
- No chargeable event now — the gain passes with the bond
- Assignment for money’s worth
- Chargeable event on the assignor now
- Surrender by discretionary trustees
- Trust rate, no top-slicing relief
- Assigned to an individual beneficiary first, then surrendered
- Beneficiary’s marginal rate, top-slicing available
Those routes are illustrative — they show where the gain lands and at what rate, not a computed figure; the amount itself is worked on the calculator below.
The common error
The frequent mistake is assuming a giftassignment triggers an income-tax charge — it doesn't, but it also doesn't reset the gain, so the recipient should know they are inheriting the whole history. The mirror error is assuming an assignment for valueis tax-neutral “because no money left the bond” — the consideration itself makes it a chargeable event. Work the resulting gain on the chargeable event gain calculator and, where relief is in point, the top-slicing relief calculator.

Common questions
- Is assigning an investment bond a chargeable event?
- Only if it is for money or money’s worth. A whole assignment for value (cash, or a valuable asset) is a chargeable event; a whole assignment by way of gift is not, and a part assignment by gift cannot be a chargeable event either (ITTOIA 2005 s.484; IPTM7360).
- Does gifting a bond to my children trigger tax?
- Not as a chargeable event. A gift assignment carries no income-tax charge at the point of transfer — but the new owner takes on the bond’s whole history, so the full gain (including pre-gift growth) is taxed on them when they later surrender it.
- How is a bond taxed once it is in a discretionary trust?
- Where the trustees are the persons liable, the gain is taxed at the trust rate and top-slicing relief — an individual’s relief — is not available. Under a bare trust the beneficiary is treated as the individual and can claim relief. Assigning the bond out to a beneficiary before surrender can change who is taxed.
