National Insurance: The Backbone of UK's Social Security

National Insurance (NI) is a cornerstone of the UK's social security system. This mandatory contribution, affecting most workers and employers, funds various state benefits. Unlike conventional insurance, NI operates on a national scale, covering over 68 million people. Its rich history dates back to 1911, evolving to meet changing societal needs. As we examine NI's past and present, we'll also explore its future in light of Labour's 2024 Autumn Budget. Understanding NI is key to grasping the UK's approach to social welfare and financial planning.

The history of National Insurance

The National Insurance system initially involved employers purchasing stamps for employee contribution cards. This manual process has since evolved into a sophisticated electronic system. A significant transformation occurred in 1948 with the introduction of the 'welfare state', which consolidated various benefit schemes into a more streamlined system.

In 1975, the flat-rate stamp system was replaced by earnings-based contributions collected alongside income tax through PAYE. This meant that individuals and employers began contributing a proportion of their income.

Unlike private insurance, National Insurance is a tax-based system. Employees, employers, and self-employed individuals all pay National Insurance Contributions (NICs), which fund state benefits and the National Health Service (NHS). This collective approach ensures a wide-ranging social safety net for UK residents.

There are different classes of NICs, with specific purposes:

• Class 1: Paid by employees and employers
• Class 2 and 4: Paid by self-employed individuals
• Class 3: Voluntary contributions to fill gaps in NI records

The amount a person pays depends on their earnings and their employment status. For the 2024/25 tax year, employees are paying 12% on earnings between £242 and £967 per week and 2% on earnings above £967 per week.

The National Insurance Fund (NIF) serves as a repository for National Insurance Contributions (NICs), operating on a current-need basis. This system is structured to manage variations in inflows and outflows, maintaining sufficient reserves to address periods of heightened demand, such as during economic downturns with increased unemployment claims.

Throughout its history, National Insurance has been subject to numerous reform proposals. Notable changes were implemented by former Chancellor Nigel Lawson and ex-Prime Minister Gordon Brown, with a primary focus on alleviating the financial burden on lower-income workers and their employers. These reforms have shaped the evolving landscape of the UK's social security system, adapting it to meet changing economic and social needs.

NI in the 2024 budget

Rain Newton-Smith, CEO of the Confederation of British Industry (CBI), said that a rise in National Insurance would be seen by employers as a "challenging decision", as it would "raise the expenses of hiring new staff".

Alex Veitch, Policy Director at the British Chambers of Commerce, voiced concern that increasing employer National Insurance contributions would "stifle growth and reduce the funds available for businesses to invest in their workforce."

Many people see that the taxes will be important for reinvigorating much of the UK's underfunded public services. 

In a statement issued alongside the Autumn budget, the UK Government shared that the taxes "will go directly towards fixing the foundations and funding public services such as the NHS and education."

Labour Chancellor Rachel Reeves acknowledged the impact of the changes.

"I mentioned that there will be consequences. Businesses will need to absorb some of this through their profits, which likely means that wage increases may be slightly less than they would have been otherwise.

"We are asking businesses to contribute more and I know that there will be impacts of this measure felt beyond businesses. But in the circumstances that I have inherited, it is the right choice to make.
