Core Mathematical FormulaStatutory 2026-27
Net Take-Home = Gross Salary − Income Tax (20%/40%/45%) − National Insurance (8%/2%) − Pension Contribution − Student Loan Repayment

Statutory Allowances & Deductions

Basic Personal Allowance / Exemption

Standard £12,570 Personal Allowance provides 100% tax-free income on foundational earnings before the 20% basic rate applies.

Reliefs & Allowable Deductions

Workplace pension salary sacrifice reduces both Income Tax (20%/40%) and Class 1 National Insurance (8%), maximizing take-home efficiency.
