How to read a chargeable event certificate

A chargeable event certificate states the gain a bond has thrown off; it does not work out the tax. The insurer must issue one when an event produces a gain — a full surrender, a death claim, a maturity, or an excess event on a part surrender — normally within three months of the event (ICTA 1988 s.552(6); for a death or an assignment, within three months of being told of it). HMRC receives its own copy only where the gain, with any connected gains, exceeds half the basic rate limit, or the event is an assignment of the whole policy for value (s.552(2); IPTM7145). Your client’s self-assessment keys off it. For a part surrender the event is dated to the end of the insurance year, so the certificate can arrive after the tax year in which the cash was paid. Reading it well, and knowing what it leaves for you to do, is most of the job.

What it is, and when it turns up

The insurer has a statutory duty to issue one whenever a chargeable event produces a gain (ICTA 1988 s.552). On a full surrender, death or maturity it’s automatic. On part surrenders it follows the periodic calculation at the end of the insurance year, where cumulative withdrawals exceed the cumulative 5% allowance (IPTM3560). Hold onto what it does not do: it reports the event and the gain, but it does not apply top-slicing relief, and it doesn’t know your client’s other income — so it can’t tell you the tax due.

The four fields that actually matter

Most of the certificate is reference detail. Four fields do the real work. Take a certificate for Helen’s onshore bond — a full surrender after six complete years:

Worked-example basis: No time-apportioned reduction is due for any gain or policy shown. TAR is not calculated or applied. Raw gains are shown before any TAR.

The gain before any TAR (£50,000) is the surrender value plus any past withdrawals, minus premiums and any gains already taxed on earlier excess events. It’s the headline number, but it’s the whole gain, not the taxable amount after relief. The complete years (6) drive top-slicing; the certificate states them, but check them against the policy. For a full surrender, death, maturity or whole assignment, N is the number of complete 12-month periods from the start of the policy (or the earliest related policy) to the event — not insurance years, and never with a +1 for the tax year the last anniversary falls in (IPTM7560). A part-surrender (excess event) certificate uses a different clock: from the end of the insurance year of the previous excess event, or from the start if there was none, to the end of the insurance year of this one (ITTOIA 2005 s.536(2); IPTM7560) — though an offshore policy issued before 6 April 2013 counts from commencement (IPTM3830), unless on or after that date it was varied to increase its benefits (exercising a right counts), assigned to the client or into or out of a trust (HMRC IPTM3731 counts both), or used as security for the client’s debt (FA 2013 Sch 8 para 7(2)-(3)), when it counts from the previous excess event as above. A period of non-UK residence can reduce N (s.536(7)). The slice (£8,333.33) is the gain divided by the years — the figure top-slicing relief actually works on. The certificate often doesn’t print it, so you derive it. And the tax treated as paid (£10,000) is the onshore basic-rate credit — the field people get wrong, so it earns its own section.

The “tax treated as paid” field — the one that’s misread

On an onshore bond the life fund has already borne tax inside the fund, so your client is treated as having paid basic-rate tax on the gain. The certificate prints that as a flat 20% of the gain before any TAR — £10,000 on Helen’s £50,000 (for events in 2026/27; 22% for events from 6 April 2027, when the savings basic rate rises under Finance Act 2026 s.5) — because the insurer cannot know the client’s wider tax position. Carry it into the computation with one qualification: the credit is restricted under ITTOIA 2005 s.530(3)–(5) to the gain less the deductions made from it at Step 2 or Step 3 of the ITA 2007 s.23 calculation — reliefs as well as the personal allowance — so where unused allowance, or a Step 2 relief, covers part of the gain, the usable credit is smaller than the printed figure. Either way it is a credit against the liability, not a cheque. A non-taxpayer can’t reclaim it, and it only ever reduces tax, never turns it negative. An offshore certificate shows nothing in this box: the fund rolled up gross and the whole gain is untaxed at source. Read an offshore certificate as if it carried the onshore credit and you’ll understate the bill; do the reverse and you’ll overstate it. The credit is a fact about the bond type printed on the certificate, not a choice you make.

What the certificate doesn’t tell you

Three things it leaves for you. It states the gain, not the tax — top-slicing relief still has to be run, on your client’s actual income, before you know the liability. It can’t tell you whether the same cash would have been cheaper taken as whole segments rather than a part surrender — that route is chosen before the money moves, not on the certificate after. And because it lands after the money has moved, it’s a record of a decision already made, not a lever you can still pull.

The common error

There are two, really. The first is taking the certificate’s gain straight to a tax figure without top-slicing, which throws away the relief the whole regime is built around. The second is treating the certificate as the start of the planning when it is the end of it. Run the gain through the chargeable event gain calculator to confirm the figure and the slice, then take both to the top-slicing relief calculator for the five-step computation on your client’s income. If the certificate is for a part surrender, the route that should have been weighed first is in part surrender vs segment surrender.
