Primary earnings threshold meaning

The pay level at which an employee starts to incur Class 1 primary National Insurance contributions (NICs) under PAYE. Below the primary earnings threshold (often called the “primary threshold” or PT), no employee NICs are payable. Where earnings fall between the Lower Earnings Limit (LEL) and the PT, the employee pays no NICs but accrues entitlement for certain state benefits. Employer NICs are not determined by this threshold; they arise separately once earnings exceed the Secondary Threshold (ST). The PT is set by statute and updated for each tax year, with figures specified by pay period (weekly, monthly, etc.). Usage and effect are consistent across England & Wales, Scotland and Northern Ireland, with parallel provisions in the Northern Ireland social security legislation. It is a core concept in payroll compliance, employment documentation (e.g. gross-up clauses), salary sacrifice assessments and HMRC reporting. In Ireland, the term is not used. The nearest analogue is the employee PRSI thresholds and credits regime, which determine when PRSI becomes payable and at what rate, but these operate under different rules and terminology.
