Use the qualifying income for the selected reference return: personal self-employment and property income before expenses. Do not include PAYE salary, dividends, pensions, savings interest or your individual share of partnership profit. If a special calculation or exemption may apply, choose it below rather than guessing.

If you are an individual partner with separate sole-trade or property income, choose that personal source and leave partnership profit out of the income figure.
