DH received a letter today from HMRC saying that they have registered him for self assessment. He is PAYE and earns £80,000 per year with an annual bonus. Does anyone know what we should do next please? I'm guessing this means they want him to complete a self assessment for the tax year ending April 2015? He pays tax PAYE but has bank accounts so perhaps need to pay extra tax on the small amount of interest he earns from his current accounts? We have only lived in the UK for 2 years so not really sure about the tax system works. Thanks for any advice.
