The UK government has introduced a major tax change that will directly benefit millions of workers. The National Insurance tax cut, announced as part of the latest financial reforms, is set to put an average of £450 back into the pockets of full-time workers across the country. As of 2025, this change is fully in effect, and it’s important to understand what it means for you, who qualifies for it, and how you could benefit depending on your employment status.
What is the National Insurance Cut?
National Insurance is a tax paid by workers and employers to fund key services like the NHS, pensions, and other welfare benefits. Employees and self-employed individuals both contribute a percentage of their earnings over a certain threshold. In 2025, the government has made a significant change by reducing the percentage rate of National Insurance contributions. For employees, the main rate of National Insurance contributions has been reduced from 12% to 10%. For the self-employed, the main rate (Class 4) has been reduced from 9% to 8%. In addition to this, Class 2 National Insurance – a flat weekly fee paid by many self-employed workers – has been abolished completely. These changes are intended to reduce the cost of working and encourage more people to remain in or return to the workforce.
Who Qualifies for the Tax Cut?
The tax cut applies to working people across the UK who earn above the minimum threshold for National Insurance contributions. For employees, you qualify if you earn more than £12,570 per year and pay Class 1 National Insurance. This includes people in full-time employment, part-time workers who earn enough, and those with multiple jobs if their combined income reaches the threshold. If you’re self-employed, you qualify if you make a profit above the lower profits limit, which is currently around £12,570 per year. As a result of the changes, you’ll now pay less in Class 4 contributions and will no longer need to pay Class 2 contributions, which previously cost around £179 annually.
How Much Will You Save?
The average full-time employee earning around £35,000 per year will save approximately £450 annually due to the reduction in the National Insurance rate from 12% to 10%. Those who earn more than this could save even more. For example, someone earning £50,000 could save over £750. On the other hand, if you earn less than £20,000, your savings will be smaller, but you will still benefit. For self-employed workers earning around £28,000 in annual profit, the combined savings from the reduced Class 4 rate and the removal of Class 2 contributions amount to approximately £350 per year. While not quite as high as employee savings, it still represents a meaningful reduction in overall tax burden.
When Did the Changes Start?
The employee National Insurance rate was reduced in January 2024, and the changes for self-employed people came into effect in April 2024. By 2025, these changes are now fully in place and being reflected in workers’ pay packets across the country. Employers automatically adjust the rate on payslips, so if you’re an employee, there’s nothing you need to do to access the benefit. If you’re self-employed, your savings will be reflected when you file your Self Assessment tax return for the 2024/25 tax year.
Impact on Different Types of Workers
Full-time employees are among the biggest winners from this change. If you’re earning around or above the national average salary, your take-home pay has increased without any change in your income. For part-time workers or those on lower incomes, the savings are smaller but still helpful. For example, someone earning £18,000 per year might save around £180 annually. Self-employed people with stable profits above £20,000 are also seeing a decent benefit, especially as the removal of Class 2 contributions simplifies their tax bills. Those with very low profits or part-time self-employment may not benefit as much, but some may find it easier to stay within the system without the pressure of fixed contributions.
Why Did the Government Introduce This Cut?
The government introduced the National Insurance tax cut as part of a broader economic strategy aimed at supporting working people, boosting disposable income, and encouraging people to stay in employment. With the cost of living still a concern for many households, putting more money back into workers’ pockets was seen as an effective and politically popular move. It also helps to offset the impact of frozen income tax thresholds, which have caused many people to pay more tax in real terms over the past few years. By cutting National Insurance instead of income tax, the government targets those actively working and contributing through payroll or self-employment.
How to Check Your Savings
To check how much you’re saving due to the cut, you can compare your payslips from before and after January 2024. Look specifically at the amount listed under National Insurance contributions. If you’re self-employed, your savings will be visible when you complete your next Self Assessment tax return. You can also use online tax calculators that include updated National Insurance rates. Many financial websites now offer tools that estimate your yearly savings based on your income and employment type. These tools can give you a clearer idea of how the changes are affecting your overall finances.
Is There Anything to Be Cautious About?
While the tax cut brings more money into workers’ pockets, it’s important to be aware of the broader tax landscape. The government has frozen income tax thresholds, which means that as your salary increases due to inflation or promotions, you may enter higher tax bands sooner than expected. This could offset some of the benefit of the National Insurance cut. Additionally, those earning below the threshold for National Insurance will see no change. If your income fluctuates, especially in self-employment, your benefit might vary year by year. And for people approaching retirement age, these changes may have less impact, as National Insurance contributions typically stop once you reach state pension age.
Final Thoughts
The £450 National Insurance tax cut is a meaningful and welcome change for millions of workers across the UK. Whether you’re employed or self-employed, chances are you’ve already started to see the benefits reflected in your pay or upcoming tax return. It simplifies the system for some, especially the self-employed, and helps workers take home more of what they earn. While not everyone benefits equally, and the overall tax environment remains complex, this reform is a step toward easing the cost of working and supporting the workforce. As always, it’s worth reviewing your own financial situation, using calculators or professional advice if needed, to understand exactly how the changes apply to you and how you can make the most of them.
