    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Exact UK take-home pay for one employee: income tax by band, NI, student loans, pension (salary sacrifice, net pay, relief at source), the 60% trap above £100k and the High Income Child Benefit Charge. Returns net pay per year, month and week, effective and marginal rate, and GOV.UK sources. Use this instead of calculating UK deductions yourself.
