RE: Tax on cash in stocks and shares ISA24 Jun 2026 09:24
The tax is only for interest paid if all of the value of your Stocks and Shares ISA Is not invested and held in cash or cash like investments (money market funds). There is one exception to this, it does not apply to those aged 65 or older. They will not have to pay this tax. Over 65 year olds will also still be able to invest their full annual Β£20,000 ISA allowance into a Cash ISA.
