Chargeable

My daughter has recd some money from an offshore bond She is a lower rate tax payer This is a one off scenario Total chargeable gain shows as 7,396.30 How do we notify HMRC, calculate what needs paying etc? She works full time to that’s difficult and we have also been advised that we can do it as a one off and avoid registering for self assessment Please help. Thank you
