- 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
