Chargeable Event Gain Calculator

A chargeable event gain arises when you surrender, mature, or assign a life insurance bond or endowment policy for more than the total premiums paid. The gain is treated as income for income tax purposes (ITTOIA 2005 Part 4 Ch 9).

Onshore (UK) bonds receive a 20% basic rate tax credit because the insurance company has already paid tax within the fund. Offshore bonds have no such credit — the full gain is taxable at your marginal rate. Offshore bonds are useful for higher-rate taxpayers planning to cash in after retirement.

Top-slicing divides the total gain by the number of complete years the bond was held. This 'slice' is added to your income to determine the effective tax rate, which is then applied to the full gain. It prevents the entire gain from being pushed into higher-rate bands in a single year.

Yes — if you are a higher-rate taxpayer, or become one after adding the gain to your income, you must declare it on Self Assessment. The insurer should provide a chargeable event certificate (form R185(CERTA)).

Assigning a bond to a spouse can be tax-efficient if they are a basic-rate taxpayer. The gain is assessed on the assignee (recipient), not the original owner, subject to anti-avoidance rules.

You can withdraw up to 5% of the premiums paid each year without an immediate tax charge (cumulative allowance). Withdrawals above this trigger a chargeable event. Unused allowances carry forward indefinitely.

No — chargeable event gains are not subject to National Insurance contributions. They are taxed purely as income tax.

Death is a chargeable event. The gain up to the date of death is assessed on the deceased's estate in the final tax year. Executors need to report this on the deceased's final Self Assessment return.
