Changes to National Insurance Contributions (NIC) in 2024 and Beyond
The recent Autumn Budget 2024 outlined several significant changes to National Insurance Contributions (NIC), impacting both employees and employers starting next year. These changes reflect both tax cuts for individuals and increased contributions for employers, with broader implications for employment structures. Here’s a breakdown of the major NIC updates and what they mean for businesses and workers alike.
Reduced Rates for Employees’ Class 1 NIC
In a move to reduce the tax burden on employees, the government has cut the main rate of Employees’ Class 1 NIC from 12% to 8%, effective April 6, 2024. These substantial reductions are part of a broader commitment to avoid tax increases for working people. As laid out in the Labour manifesto.
What This Means: Employees will see a smaller NIC deduction on their payslips starting in April, potentially increasing take-home pay. The government aims to alleviate cost-of-living pressures while ensuring that no additional tax burdens are placed on income for employees.
Significant Increase in Employers’ NIC (ERNIC)
On the other side, employers will see an increase in their NIC obligations starting April 6, 2025. Employers’ NIC rates will rise from 13.8% to 15%, and the Secondary Threshold (the level of pay above which Employers’ NIC applies) will drop from £9,100 to £5,000. This change is expected to generate an additional £23.7–£25.7 billion in tax revenue per year from 2025/26 to 2029/30.
Impact on Businesses: While these contributions won’t appear on employee payslips, they indirectly influence hiring costs. Businesses may feel pressured to explore alternative staffing models, such as hiring self-employed contractors, to manage these increased costs. However, the rise in employers’ NIC will also add approximately £5 billion each year to the government’s own employment expenses, particularly for civil service roles.
Employment Allowance (EA) Doubled for Small Businesses
The Employment Allowance, which allows eligible businesses to reduce their Employers’ NIC bill, will increase from £5,000 to £10,500 starting April 6, 2025. Furthermore, the £100,000 cap on Class 1 ERNIC from the previous tax year. Which determined eligibility, will be removed, opening this allowance to more businesses.
Good News for SMEs: For small and medium-sized enterprises, this boost in Employment Allowance offers significant relief. Allowing them to offset some of the additional NIC costs. By widening eligibility, the government hopes to support job creation and retention within the SME sector.
Changes to Class 2 NIC for the Self-Employed
The Autumn Budget also brings changes for self-employed individuals, who have traditionally paid a flat-rate Class 2 NIC to secure state pension eligibility. From April 6, 2024, self-employed individuals earning above the small profits threshold will no longer need to pay Class 2 NIC to maintain state benefits. This threshold is set to rise from £6,725 to £6,845 in 2025/26. Those below this threshold can still choose to pay voluntarily (£182 in 2025/26) to keep a full contribution record.
Planning Tip: Self-employed individuals with variable earnings should consider making voluntary contributions if income falls below the threshold. Ensuring uninterrupted state pension eligibility.
Potential Rise in Self-Employment and IR35 Implications
With rising Employers’ NIC, some businesses may consider contracting with self-employed individuals to avoid higher payroll costs. This approach, however, brings potential complications under the IR35 rules, which aim to prevent “disguised employment.” The increase in Employers’ NIC could lead to heightened scrutiny of self-employed contracts by HMRC.
Advice for Businesses: If considering a shift to self-employed contractors, businesses should carefully assess the employment status of these individuals to ensure compliance with IR35. Misclassifying employees as contractors could lead to investigations, penalties, and unexpected tax liabilities.
