Personal tax – form

Self Assessment: register for Self Assessment and get a tax return (SA1)

Use form SA1 if you need to register for Self Assessment for a reason other than self employment.



How you register for Self Assessment depends on your circumstances. Use form SA1 if you need to register but aren’t self employed. For example, if you:

  • become a company director
  • receive income from land and property in the UK
  • have taxable foreign income of more than £300 a year
  • receive yearly income from a trust or settlement
  • sell shares, property or other assets liable to Capital Gains
  • have yearly income over £100,000
  • get untaxed income that can’t be collected through your PAYE tax code
  • have income over £50,000 and you or your partner carry on receiving Child Benefit payments
  • have Capital Gains Tax to pay
