Tax & Self Assessment tools are grouped around HMRC-facing questions: take-home pay, Income Tax, National Insurance, Child Benefit charges, student loans, self-employed profit and Making Tax Digital readiness.
These tools are designed for planning and sense-checking. They should help you understand the likely shape of a tax position, not replace official guidance, payroll records or professional advice.

Section note
Tax tools have a different risk profile from ordinary calculators. Keeping them separate makes room for clearer assumptions, official-record caveats and HMRC-specific context.
