How much non-business information must a self-employed taxpayer provide to HMRC in response to an information notice, and when is the taxman legitimately allowed to go on ‘fishing expeditions’ to gain info when they think there is a disparity in a tax return?

And that can include studying personal bank accounts. https://bit.ly/2U7mKyD
