🟢calculate_uk_take_home(gross_salary, tax_year, region, tax_code, pension_method, ...)
Calculates UK take-home pay for an employee in tax year 2025/26 or 2026/27 from HMRC's published rates: income tax by band (England, Wales and NI, or the six Scottish bands incl. the 2026/27 Scottish starter and basic bands), employee Class 1 National Insurance (8% / 2%), student loan repayments (Plan 1, 2, 4, 5 and Postgraduate, with 2026/27 thresholds), and pension by salary sacrifice or relief at source. Applies the Personal Allowance taper above £100,000 (£1 per £2, the 60% trap) and reads tax codes such as 1257L, S1257L, K475, BR and D0. Returns net pay a year, a month and a week. Figures copied from gov.uk and HMRC in Oct 2026.
