Thanks for your question
No, as these fall under the category of savings - as its the investment (saving) which generates the dividend and interest position.
HMRC word it as follows
Regular gifts or payments that are part of your normal expenditure
Any regular gifts you make out of your after-tax income, not including your
capital, are exempt from Inheritance Tax. These gifts will only qualify if you
have enough income left after making them to maintain your normal lifestyle.
monthly or other regular payments to someone
- regular gifts for Christmas and birthdays, or wedding/civil partnership
- regular premiums on a life insurance policy - for you or someone else
You can also make exempt maintenance payments to:
- your husband, wife or civil partner
- your ex-spouse or former civil partner
- relatives who are dependent on you because of old age or infirmity
- your children, including adopted children and step-children, who are under
18 or in full-time education
So as the gift would in essence be made from your capital investment any regular gifts made from this would be exempt from Inheritance tax consideration.
And even if you used these investments to live on (and had no other income) these are deemed to be after tax (although the ISA should be tax free)
If this related to anything other than regular gifts, then please advise further. It would be appreciated if you would rate the level of service I have provided, so your payment is passed to me by Just Answer.
