How to read a chargeable event certificate

When a bond pays out — a full surrender, a death claim, a maturity, or a withdrawal over the 5% allowance — the insurer sends a chargeable event certificate. It’s the document your client’s self-assessment keys off, and HMRC gets its own copy. The catch: it usually turns up months after the event, often after the tax year has already closed, and it states the gain without working out a penny of the tax. 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 (ITTOIA 2005 s.552). On a full surrender, death or maturity it’s automatic; on part surrenders it’s triggered once a withdrawal breaches the cumulative 5% allowance. The important thing to hold onto is 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, and doesn’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:

The gain (£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, because the final-year rule can change the count. The slice (£8,333.33) is the gain divided by the years — the figure top-slicing relief actually works on, and one the certificate often doesn’t print, 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’s worth 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 20% on the gain — £10,000 on Helen’s £50,000. That’s 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, because 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 tax year, it’s a record of a decision already made: the planning — the route, the timing, whether to assign the bond first — has to happen up front.

The common error

Two, really. Taking the certificate’s gain straight to a tax figure without top-slicing, which throws away the relief the whole regime is built around. And treating the certificate as the start of the planning when it’s 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.
