Chargeable gain on joint investment bond

Is there a requirement to complete self-assessment if a £18,000 chargeable gain is realised on a joint investment bond? I assume not, as the gain would be less than £10,000 for each. Please could you confirm?

Hi,

You can find guidance on Self Assessment criteria here:

Self Assessment tax returns

If under £10,000 then you will not be required to complete a return.

Thank you.
