Multiple chargeable events reporting

For tax year 23/24 I have 2 chargeable gains from cashing in investment bonds to report. I usually do a self assessment return. One gain is on a joint policy and the two gains have different lifespans . There only appears to be space to report one gain on the on-line form,so how can I report the other? Total gain from the two policies is £7,374.

Hi,
Where there are multiple chargeable event gains in a tax year, then they cannot be declared using the online tax return.  
You must submit a paper tax return.
If you have gains from different, multiple policies, you must put the following information in box 19 on page TR 7 of your tax return:
 • details of each individual policy
 • the amount of gain for each policy
 • the number of years you’ve held the policy
 • the tax paid on each gain
If your multiple policies had tax taken off, add them together and put the total amount of gain in box 4. If your multiple policies did not have tax taken off, put the total amount of gain in box 6. Do not put any figures in box 5 or box 7.
