Hi,
Gifting the bonds to your mother, may mean that you have a capital gains liability arising from their disposal. You would need to obtain their market value at the time of gifting them to your mother and deducting your allowable costs (eg. acquisition costs, brokers fees for acquistion and disposal). This gain can be further reduced by deducting the annual exempt allowance.
Any remaining gain is subject to tax and should either be declared using the capital gains realtime transaction service below or in a self assessment tax return.
Report and pay your Capital Gains Tax
Your mother would be liable to declare the dividneds arising from these share, as she is now their benficial owner.
You could write to belowadvising the shares belong to your mother, who should declare them to HMRC.
Thank you.
