I am a non-tax payer and a pensioner and my only income is an occupational pension and interest from two joint accounts belonging to myself and my husband At the end of the tax year I contact hmrc by phone and let them know how much interest is mine, as I understand it the interest is split 50/50. Is it necessary for me to inform hmrc of how much interest I have earned each year or will the banks and or building societies do that. Thank you.
