I have a related question. I am a UK citizen and using stock trading platforms registered in UK. With the general trading accounts (not ISA) , the idle cash produce very small amount of interest - say less than £20 a year . I understand that these interest are covered by income tax personal allowance but my personal allowance are normally used up before any additional income. Assuming the stock trading platforms would inform HMRC about these interest, would HMRC adjust the tax code yearly to manage these very small amount of money? Regards
