My English friend is worrying about a section in her tax return. She is a widow with an 18 year old son going off to university in Sept. She had an small endowment that matured last year £20,000 and she spent some of it on a new car and put the rest in ISA. The Pru says it was not taxed. There is a "windfall section" in the tax return. Must she declare the matured endowment? She is only working part time on low salary. She is really worrying over this, if you can help please do, or suggest someone who can - who can tell her in plain English! Many thanks.
