National Insurance Contributions (Secondary Class 1 Contributions) Act

Summary

This bill modifies how secondary Class 1 National Insurance contributions work—the taxes that employers pay on employee wages above a certain threshold. The legislation adjusts the rates, thresholds, or application of these contributions, which directly affects how much employers must pay in National Insurance for their workforce. Changes to secondary contributions influence employer costs, wage-setting decisions, and potentially employment levels across the economy.

A vote to support means

  • Reducing employer National Insurance contributions lowers business operating costs, allowing companies to invest more in wages, hiring, and expansion, particularly benefiting small and medium-sized enterprises
  • Lower employer contributions can stimulate job creation and economic growth by making employment more affordable for businesses across all sectors
  • Simplified or reformed contribution rules reduce administrative complexity and compliance costs for employers managing payroll
  • Relief from National Insurance can help UK businesses remain competitive internationally and with lower-taxed economies when recruiting and retaining talent

A vote to oppose means

  • Lower employer National Insurance contributions reduce government revenue needed to fund public services like the NHS, social care, and welfare programmes without compensating tax increases elsewhere
  • Reducing employer contributions may primarily benefit larger corporations and high-margin businesses rather than improving wages or conditions for low-paid workers
  • Changes risk widening inequality if savings are not reinvested in employee wages or public services, instead going to shareholder profits or executive pay
  • The long-term economic impact is uncertain—savings may not translate to genuine job creation or wage growth if businesses use reduced costs for other purposes
