The Implications of Raising Employer National Insurance: A Closer Look

In recent discussions surrounding the UK’s fiscal policy, the potential increase in employer national insurance (NI) contributions has sparked significant debate. Paul Johnson, the director of the Institute for Fiscal Studies (IFS), has raised concerns about the consistency of such a move with Labour’s manifesto, suggesting it could have detrimental effects on employment and wages in the long term. This article delves into the implications of raising employer NI, the political context, and the economic theories that underpin these concerns.

The Political Context

As the UK government prepares for the upcoming autumn budget, Chancellor Rachel Reeves is tasked with addressing a staggering £22 billion "black hole" in the nation’s finances. Amidst this backdrop, Sir Keir Starmer, the leader of the Labour Party, has not ruled out the possibility of increasing employer NI contributions. This has raised eyebrows, particularly since Labour’s 2024 manifesto explicitly states that the party will not raise national insurance, income tax, or VAT.

The Prime Minister has interpreted this manifesto pledge as a commitment not to increase taxes on working individuals, leaving the door ajar for potential hikes in employer NI. This interpretation has led to a growing concern among economists and political analysts about the implications of such a decision.

The Economic Theory Behind National Insurance Contributions

Paul Johnson’s insights into the economic ramifications of increasing employer NI contributions are grounded in established economic theory. He argues that any hike in employer NI ultimately impacts employees, as the costs are likely to be passed down in the form of lower wages or reduced job opportunities.

The Burden of Taxation

Johnson emphasizes that all taxes are ultimately borne by individuals—whether they are shareholders, customers, or employees. In the case of employer NI, the burden is expected to fall primarily on employees. Historical data and economic theory suggest that increases in employer taxes often lead to stagnated wage growth and, in some instances, job losses.

He states, "Most of the theory and the evidence suggests that most of the increase will be felt by employees in lower wages, probably, but possibly in the longer term, fewer jobs than there otherwise would have been." This perspective aligns with the broader economic understanding that businesses may respond to increased costs by reducing their workforce or limiting pay raises.

The Current Structure of National Insurance

Currently, employers pay NI at a rate of 13.8% on all employee earnings exceeding £175 per week. Notably, pension contributions made by employers are exempt from this levy, a point that experts suggest could be targeted for reform. Employees and the self-employed also contribute to NI, which is deducted directly from their earnings.

The government has assured that the employee component of NI will not increase in the upcoming budget, but the potential for changes to employer contributions remains a contentious issue.

The Potential Consequences of Increasing Employer NI

The implications of raising employer NI contributions are multifaceted. While the government may view this as a necessary step to address fiscal shortfalls, the long-term consequences could be counterproductive.

Impact on Wages

As Johnson points out, increasing employer NI could lead to "less pay rises" for employees. This stagnation in wage growth can have a ripple effect on the economy, as lower disposable income may reduce consumer spending, ultimately hindering economic growth.

Job Losses

In the longer term, the potential for job losses cannot be overlooked. Businesses facing higher operational costs may resort to downsizing or freezing hiring to maintain profitability. This could exacerbate unemployment rates and create a more precarious job market.

Conclusion

The debate surrounding the potential increase in employer national insurance contributions is emblematic of the broader challenges facing the UK government as it navigates fiscal constraints. While the immediate goal may be to fill a financial gap, the long-term implications for employees, wages, and job security warrant careful consideration. As Paul Johnson aptly notes, the economic theory and empirical evidence suggest that the burden of such tax increases will ultimately fall on the workers, potentially leading to a less favorable economic landscape for all.

As the Chancellor prepares to unveil the budget, the decisions made will not only reflect the government’s fiscal strategy but also shape the future of employment and economic stability in the UK. The balance between addressing financial shortfalls and ensuring a thriving workforce will be crucial in the coming months.
