Key Updates from the 2024 Autumn Budget
The 2024 Autumn Budget introduced several significant changes that directly affect contractors, particularly in the areas of National Insurance Contributions (NICs), wages, and employment regulations.
Employer National Insurance Contributions (NICs)
Starting in April 2025, the rate for employer NICs will rise from 13.8% to 15%. This change will impact umbrella companies and recruitment agencies that employ contractors. If you’re working through an umbrella company, it’s essential to consider how this increase could affect your take-home pay.
National Minimum Wage
From April 1, 2025, the National Living Wage will increase to £12.21 per hour. Contractors should ensure that their rates meet or exceed the new minimum standards to comply with the updated wage regulations.
Umbrella Company Regulation Changes
The Autumn Budget proposed shifting the Pay As You Earn (PAYE) responsibilities from umbrella companies to recruitment agencies. This change aims to improve compliance and better protect workers’ rights. It’s essential to stay informed about these changes to understand how it might impact your role.
Increased Employment Allowance
The Employment Allowance, which helps small employers reduce their NICs liability, will rise from £5,000 to £10,500. This change could benefit contractors operating through limited companies with employees, providing some relief in their NICs obligations.
