Employee and employer National Insurance, explained with your numbers

National Insurance is charged separately on the employee and employer side, at different rates and different thresholds, and it's easy to see only the employee deduction on a payslip without realising how much the employer side actually costs to employ someone. For 2026/27, employee Class 1 NI is 8% between £12,570 and £50,270 and 2% above that, while employer Class 1 NI is 15% on everything above a £5,000 secondary threshold — a much lower starting point than the employee side, which is why employer NI adds up quickly even for modest salaries.
