    Description, as the server wrote it
    Free estimate for UK sole traders. Maps each expense to an HMRC Self Assessment self-employment (SA103F) expense category using simple keyword rules (no AI), with a confidence level, and flags items that are usually not allowable or need care (entertaining, everyday clothing, fines, private use, depreciation, capital items, mixed-use phone/car/home). Totals per category when amounts are given.

    Description, as the server wrote it
    Free estimate for UK sole traders. Checks annual turnover against the VAT registration threshold (flags "near" within 10%), explains the rolling 12-month and 30-day forward-look rules, and says whether and from when Making Tax Digital for Income Tax applies. Give the optional qualifying income for each tax year for a definite answer; with only turnover it gives an estimate.
