How National Insurance (Isle of Man) works in Isle of Man
Isle of Man National Insurance is administered by the Department of Health and Social Care (DHSC) in the Isle of Man. It funds the Manx National Insurance Fund, which pays contributory benefits including state pension, maternity allowance, sickness benefit, and unemployment benefit.

The Manx NIC system broadly mirrors the UK but the rates, limits, and thresholds are set independently by the Isle of Man Tynwald rather than by Westminster. This means they can diverge over time from UK rates. The Manx employer rate of 12.8% is slightly lower than the UK employer rate of 13.8% (2025/26).
