How April 2025 Employer NIC Increase Impacts Your Take-Home Pay

O n 6 April 2025, the Employers’ National Insurance Contribution (NIC) rate will increase from 13.8% to 15% for all PAYE employers, including umbrella companies that process contractor wages. This change stems from the government’s efforts to raise revenue to fund public services, but it may reduce contractors’ net take-home pay if umbrella fees and calculations aren’t adjusted appropriately.

What the NIC Increase Means

Employers’ NICs are payable on earnings above the secondary threshold (£9,100 per annum).

The 1.2 percentage point rise means employers must budget more for contributions, potentially passing costs onto contractors through reduced net pay or higher umbrella fees.

Impact on Umbrella Payroll

Many umbrella companies factor the NIC rate into their payroll calculations. Without proactive adjustments, contractors could see a drop in net earnings of up to 1%–2% of gross pay, depending on contract rates and fee structures. Contractors should review their pay calculations to understand the precise impact.
