In the UK, inheritance tax is charged at 40% on any value that takes your estate over the threshold of £325,000.
Your estate is made up of any property, possessions and savings you own, therefore your estate could easily go over this threshold.
Your life insurance policy will also form part of your estate after your passing, unless it’s written in trust.
Writing your life insurance policy in trust could detach the pay out from your estate. Instead, a trustee (of your choosing) will be placed in charge of the pay out and will distribute the funds as per your wishes (similar to the executor of a Will).
This helps to minimise/avoid inheritance tax on the pay out.
Often, life insurance policies are written in trust with the aim of the funds covering any inheritance tax bills that are required on your estate.
