National Insurance Contributions in the U.K.

Changes to National Insurance Contributions (NICs) in the U.K.

In the dynamic landscape of payroll and tax regulations, staying abreast of changes is crucial for employers and payroll service providers. One recent development in the United Kingdom’s National Insurance Contributions (NICs) has significant implications for both employees and employers. This blog post will delve into the modifications made between April 2023 and January 2024, shedding light on the alterations to NICs rates and thresholds.

Changes to Employee NICs Rates:

Between April 6, 2023, and January 5, 2024, employees faced a 12% NICs rate on earnings between the primary threshold and the upper earnings limit. However, a notable shift occurred on January 6, 2024, when the main rate was reduced to 10%. Earnings surpassing the upper earnings limit became subject to a 2% rate.

It’s crucial to note that these adjustments were announced in Chancellor Jeremy Hunt’s Autumn Statement 2023, signaling a proactive approach to ease the burden on employees and stimulate economic growth.

Employer NICs Rates:

For employers, the NICs rate remained unchanged at 13.8% on earnings above the secondary threshold. This stability ensures consistency for employers, allowing them to plan their payroll obligations effectively.

Thresholds for 2023/24:

Several key thresholds remained unchanged from the previous fiscal year (2022/23). The primary threshold stood at £242 per week, the secondary threshold at £175 per week, and the upper earnings limit at £967 per week. This alignment with the income tax higher rate threshold underscores the government’s commitment to maintaining a balanced fiscal policy.

Historical Context:

Understanding the recent changes requires a brief look at the historical context. In the Spring Statement 2022, Chancellor Rishi Sunak announced an increase in the primary threshold from £190 to £242. This adjustment aimed to mitigate the impact of the 1.25 percentage point rise in NICs rates for 2022/23, part of the introduction of the Health and Social Care Levy.

However, a subsequent reversal was announced on September 22, 2022, by Chancellor Kwasi Kwarteng. The 1.25 percentage point rise in NICs rates was reversed from November 6, 2022, and the Health and Social Care Levy was canceled.


In summary, the recent changes to National Insurance Contributions in the U.K. signify a nuanced response to economic and fiscal challenges. The reduction in employee NICs rates and the stability of employer rates provide relief and predictability. Employers and payroll service providers, like Paycheck Plus, should stay vigilant to ensure compliance and effective payroll management in light of these evolving regulations.
