I've been self-employed for 25 years, done various jobs, bought and sold properties affected by capital gains tax, had tenants, so lots of tax and VAT issues during that time. I tend to keep everything, just in case Inland Revenue or VAT ever want to query my returns.
But how far back should I go? Do I really need all my bank statements since 1990? What about tax receipts - is there a cut-off after which my declarations can't be challenged?
all help gratefully received
