What Is Class 4 National Insurance? | The Ultimate Class 4 NIC Guide

Updated: Jan 11

Class 4 National Insurance is a type of National Insurance contribution that is paid by self-employed individuals in the United Kingdom. It is one of several types of National Insurance contributions, which are a tax levied by the government on earned income and used to fund various social security programs in the UK.


What Is Class 4 National Insurance


How is Class 4 National Insurance Calculated?

Class 4 National Insurance Contributions (NICs) are a crucial aspect of the UK tax system, primarily impacting self-employed individuals. Understanding how these contributions are calculated, including the latest thresholds and facts, is essential for self-employed professionals to manage their finances effectively.


Understanding Class 4 NICs

Class 4 NICs are paid by self-employed individuals earning a profit above a certain threshold. These contributions are calculated as a percentage of annual taxable profits and are included in the Self Assessment tax return.


Calculation Method

The calculation of Class 4 NICs involves two main thresholds:

  1. Lower Profits Limit (LPL): This is the minimum level of profits at which Class 4 NICs start to be paid. For the tax year 2024-25, the LPL is set at £12,570 annually. Below this threshold, no Class 4 NICs are due.

  2. Upper Profits Limit (UPL): This is the level of profits above which the rate of Class 4 NICs drops. The UPL for 2024-25 is set at £50,270. Profits above this limit are charged at a lower rate.

The calculation of Class 4 NICs for 2024-25 involves two rates:

  • Main Rate: This is charged on profits between the LPL and the UPL. For 2024-25, the main rate has been reduced to 8% (down from 9% in previous years).

  • Additional Rate: Profits above the UPL are subject to the additional rate of 2%.


Example of Calculation

To illustrate, consider a self-employed individual with an annual profit of £55,000 in the tax year 2024-25. The Class 4 NICs would be calculated as follows:

  • On the first £12,570 (up to the LPL), no NICs are due.

  • On the next £37,700 (£50,270 - £12,570), the main rate of 8% applies, resulting in NICs of £3,016 (£37,700 * 8%).

  • On the remaining £4,730 (£55,000 - £50,270), the additional rate of 2% applies, resulting in NICs of £94.60 (£4,730 * 2%).


Therefore, the total Class 4 NICs payable would be £3,110.60 (£3,016 + £94.60).


Other Relevant Facts for 2024-25

  • Class 2 NICs: From 6 April 2024, self-employed individuals with profits above £12,570 will no longer be required to pay Class 2 NICs. However, they will continue to receive access to contributory benefits like the State Pension.

  • Small Profits Threshold (SPT): The SPT, the point at which the self-employed start to receive National Insurance credits, is frozen at £6,725 for 2024-25. This threshold is significant for those with lower profits, as it allows them to maintain access to contributory benefits without having to pay NICs.

  • Voluntary Contributions: Those with profits under £6,725, and others who pay Class 2 NICs voluntarily to get access to contributory benefits, will continue to be able to do so. The weekly rate they pay will be frozen at £3.45 for 2024-25.

  • Tax Simplification: The reduction in the Class 4 NICs rate and the abolishment of the requirement to pay Class 2 NICs are measures aimed at simplifying the tax system for the self-employed.


Impact of Class 4 NICs Changes

These changes, particularly the reduction in the Class 4 NICs rate and the removal of Class 2 NICs for those above the profit threshold, represent a significant shift in the tax landscape for self-employed individuals in the UK. It not only simplifies the tax system but also provides tax relief, potentially improving cash flow and financial stability for the self-employed.


Understanding how Class 4 NICs are calculated is vital for self-employed individuals in the UK. The latest changes in the tax year 2024-25, including the reduced rates and adjusted thresholds, are designed to simplify the tax system and provide some relief to self-employed professionals. Staying informed about these changes is crucial for effective financial planning and compliance.

What are National Insurance Contributions in the UK?

National Insurance Contributions (NICs) are a type of tax levied by the UK government on earned income. The purpose of NICs is to fund various social security programs in the UK, including the state pension, unemployment benefits, and health benefits such as the National Health Service.


In addition to funding social security programs, NICs are also used to build up an individual's National Insurance record, which is used to determine their eligibility for certain benefits, such as the state pension. To be eligible for the state pension, individuals must have paid or been credited with enough National Insurance contributions over the course of their working life.


It is important for individuals to make sure they are paying the correct amount of NICs, as failure to do so can result in fines and penalties. Employers are responsible for deducting NICs from their employees' pay and paying them to HM Revenue & Customs, while self-employed individuals are responsible for paying their Class 2 and Class 4 National Insurance Contributions through their Self Assessment tax return.


Where is Money Raised through Class 4 NICs Used?

The money raised through Class 4 National Insurance contributions is used to fund various social security programs in the UK, including the state pension, the National Health Service, and other benefits such as Jobseeker's Allowance and Employment and Support Allowance. These programs provide support to individuals who are unable to work due to illness or disability, as well as to those who are out of work and looking for employment.


Where are the Benefits of Class 4 NICs?

One of the key benefits of paying Class 4 National Insurance contributions is that it helps individuals build up their National Insurance record, which is used to determine eligibility for the state pension. The state pension is a weekly payment made to individuals who have reached the state pension age and have contributed enough National Insurance over the course of their working life. By paying Class 4 National Insurance contributions, self-employed individuals can help ensure that they are eligible for the state pension when they reach retirement age.


Another important benefit of paying Class 4 National Insurance is access to certain benefits and support programs. For example, self-employed individuals who have paid Class 4 National Insurance contributions for at least 26 weeks may be eligible for Jobseeker's Allowance if they become unemployed. Additionally, individuals who have paid Class 4 National Insurance contributions for at least 39 weeks may be eligible for Employment and Support Allowance if they become ill or disabled.


It is important for self-employed individuals to accurately calculate their Class 4 National Insurance contributions and pay them on time, as failure to do so can result in fines and penalties. Self-employed individuals can calculate their Class 4 National Insurance contributions using HM Revenue & Customs' online calculators and can pay their contributions through their Self Assessment tax return.



How to Register for Class 4 National Insurance Contributions in the UK?

Registering for Class 4 National Insurance Contributions (NICs) is a critical step for self-employed individuals in the UK. This process ensures compliance with tax obligations and contributes towards eligibility for certain state benefits. Below is a comprehensive guide on how to register for Class 4 NICs, including key steps and important considerations.


Step-by-Step Guide to Register for Class 4 NICs


Determine Eligibility

  • Upon registering as self-employed, HMRC will issue a Unique Taxpayer Reference (UTR). This number is crucial for filing your Self Assessment tax return.

Enroll for Self Assessment

  • You must enroll for Self Assessment, which is the system HMRC uses to collect Income Tax. Class 4 NICs are calculated and paid through this system based on your annual Self Assessment tax return.

Keep Accurate Financial Records

  • Maintain detailed records of your income and expenses. These records are essential for accurately calculating your taxable profit and, consequently, your Class 4 NICs.

Complete Your Self Assessment Tax Return

  • Annually, you'll need to complete a Self Assessment tax return. This return will detail your earnings and expenses for the year, and HMRC will use this information to calculate your Class 4 NICs due.

Understand Payment Deadlines

  • Be aware of the deadlines for filing your tax return and paying your Class 4 NICs. The deadline for online tax returns is 31 January following the end of the tax year, and this is also the deadline for paying any NICs owed.


Additional Considerations


  • Voluntary Payments: If your profits are below the LPL, you can choose to make Class 2 NICs voluntarily to maintain access to certain benefits.

  • National Insurance Credits: In some situations, such as low earnings or certain types of work like caregiving, you might be eligible for National Insurance Credits, which can help fill gaps in your NIC record.

  • Seek Professional Advice: If you're unsure about any part of the process or your obligations, consult a tax professional. They can provide tailored advice and assistance.

  • HMRC Penalties: Late registration, non-compliance, or late payments can result in penalties and interest charges from HMRC.

  • Digital Tools and Apps: Utilize digital tools and accounting software to keep track of your earnings and expenses. These can simplify the process of filing your tax return.


Online Registration Process

Who Is Exempt from Paying Class 4 National Insurance in The UK?

Class 4 National Insurance Contributions (NICs) form a key part of the UK’s tax system, specifically targeting the earnings of self-employed individuals. However, not all self-employed individuals are required to pay these contributions. Understanding who is exempt is crucial for compliance and financial planning. This comprehensive guide covers the criteria for exemption from Class 4 NICs.


Categories of Individuals Exempt from Class 4 NICs


  1. Earnings Below the Lower Profits Limit

  • If your annual profits are below the LPL (£12,570 for the tax year 2024-25), you are exempt from paying Class 4 NICs.

  1. State Pension Age

  • Individuals who have reached State Pension age are exempt from Class 4 NICs. This age is currently 66 for both men and women and is scheduled to rise in the future.

  1. Non-Profit Earning Activities

  • If your activities do not generate a profit, such as hobbyist activities or non-commercial ventures, you might be exempt as these are not considered ‘trade’ for NIC purposes.

  1. Certain Religious Groups

  • Members of certain religious groups who have ethical objections to insurance, including State Insurance, might be exempt if they have been granted a Certificate of Exception by HMRC.

  1. Special Cases

  • In rare cases, such as certain types of trust income, or in specific roles like examiners or visiting lecturers, exemptions might apply.


Understanding Exemptions


  1. Income Level

  • It's important to accurately calculate your annual profits to determine if they fall below the LPL. This includes accounting for all allowable business expenses and reliefs.

  1. Age Consideration

  • Keep track of your age in relation to the State Pension age. Once you reach this age, you should inform HMRC to ensure you are no longer charged Class 4 NICs.

  1. Nature of Activities

  • Evaluate the nature of your activities. If they are not profit-driven or fall into a special category, you may be exempt.

  1. Religious Exemptions

  • For religious exemptions, rigorous criteria must be met, and official recognition from HMRC is required.

  1. Checking for Special Cases

  • Review your specific circumstances against HMRC guidelines to ascertain if any special cases apply to you.


Impact of Exemption


  1. State Benefits

  • Being exempt from Class 4 NICs means you might not accumulate qualifying years towards the State Pension or certain other state benefits. This could affect your entitlements later.

  1. Financial Planning

  • If you're exempt, consider alternative ways to prepare for retirement or ill health, such as personal pensions or savings.

  1. Record-Keeping

  • Maintain accurate financial records, regardless of your exemption status. This can be crucial if your circumstances change or if HMRC requires evidence of your exemption status.


Seeking Professional Advice


  • Complex Cases: If your situation is complex, or if you are unsure whether you qualify for an exemption, consult a tax professional.

  • HMRC Queries: For any doubts or to confirm your exemption status, you can directly contact HMRC.


Exemption from Class 4 National Insurance in the UK is primarily based on income level, age, nature of your activities, or special cases like religious objections. Understanding these criteria is crucial for self-employed individuals to ensure they are compliant with their NIC obligations. Regularly reviewing your circumstances and seeking professional advice when needed are key to effectively managing your tax and NIC responsibilities.


It is important to note that exemptions from Class 4 NICs do not affect your eligibility for benefits such as the state pension. To maintain your National Insurance record and ensure that you are eligible for benefits in the future, you should still pay Class 2 NICs if you are self-employed and earning above the Lower Earnings Limit, which is currently £184 per week.


Individuals who are self-employed in the UK may be exempt from paying Class 4 NICs under certain circumstances, such as low earnings, reaching state pension age, or receiving certain benefits. However, it is important to check your eligibility and pay Class 2 NICs if you are self-employed and earning above the Lower Earnings Limit to maintain your National Insurance record and ensure that you are eligible for benefits such as the state pension in the future.



Do You Have to Pay Both Class 2 and 4 National Insurance?

In the UK, self-employed individuals may need to pay both Class 2 and Class 4 National Insurance Contributions (NICs), depending on their earnings. Understanding when each class applies and how they are calculated is essential for managing tax obligations effectively.


Understanding Class 2 and Class 4 NICs

  • Class 2 NICs: These are a flat-rate weekly charge paid by self-employed individuals. Class 2 NICs contribute towards entitlements such as the State Pension and other benefits.

  • Class 4 NICs: These are earnings-related and are paid on profits from self-employment. Class 4 NICs do not count towards State Pension or benefits.


Who Pays Class 2 and Class 4 NICs?

  • For Profits above the Lower Profits Limit (LPL): If your profits are above the LPL (£12,570 for the tax year 2024-25), you are required to pay both Class 2 and Class 4 NICs. However, from April 2024, self-employed individuals with profits above this threshold will no longer be required to pay Class 2 NICs.

  • For Profits between the Small Profits Threshold (SPT) and LPL: If your profits fall between the SPT (£6,725 for 2024-25) and the LPL, you are not liable for Class 4 NICs but may still have to pay Class 2 NICs to maintain benefits entitlement.

  • For Profits below the SPT: If your profits are below the SPT, you are not required to pay Class 2 NICs but can choose to pay them voluntarily to keep up your entitlements to certain benefits, including the State Pension.


Different Scenarios


Scenario 1: High Earnings (Above £12,570)

  • Prior to April 2024: Pay both Class 2 and Class 4 NICs.

  • From April 2024: Pay only Class 4 NICs (8% between £12,570 and £50,270, and 2% on profits above £50,270).

Scenario 2: Moderate Earnings (Between £6,725 and £12,570)

  • Obligated to pay Class 2 NICs to retain benefits access.

  • Exempt from Class 4 NICs.

Scenario 3: Low Earnings (Below £6,725)

  • Not required to pay Class 2 NICs, but may opt to do so voluntarily.

  • Exempt from Class 4 NICs.


Impact of the Changes in 2024

  • The removal of the obligation to pay Class 2 NICs for those with profits above £12,570 simplifies the tax system and reduces the financial burden on self-employed individuals.

  • Those with profits between the SPT and LPL can continue to pay Class 2 NICs voluntarily, ensuring their access to contributory benefits like the State Pension.

  • The freezing of the weekly Class 2 NICs rate at £3.45 for the tax year 2024-25, rather than an increase in line with CPI, provides financial relief, particularly for those with lower profits.


Calculating Your NICs

Here's how you can calculate your NICs based on the 2024-25 thresholds:


Earnings above £12,570:

  • Calculate 8% of the profits between £12,570 and £50,270 for Class 4 NICs.

  • Calculate 2% of any profits above £50,270 for Class 4 NICs.

Earnings between £6,725 and £12,570:

  • Pay the flat rate of £3.45 per week for Class 2 NICs (if opted).

Earnings below £6,725:

  • Consider paying £3.45 per week voluntarily for Class 2 NICs to maintain benefit entitlements.


The decision to pay Class 2 NICs, especially for those with lower earnings, should be based on individual circumstances and future benefit requirements. With the changes in 2024, self-employed individuals with higher earnings will benefit from a simplified tax system and reduced NICs burden, while those with lower earnings continue to have options to maintain their benefits entitlement. Understanding these nuances is crucial for effective financial and tax planning for self-employed individuals in the UK.


Do You Have to Pay Both Class 2 and 4 National Insurance?


Individuals who are self-employed in the UK may be required to pay both Class 2 and Class 4 NICs, depending on their earnings. Class 2 NICs are used to build up your National Insurance record, while Class 4 NICs are used to fund the NHS and other benefits in the UK. To ensure that you are paying the correct amount of NICs and maintaining your National Insurance record, it is important to keep accurate records of your self-employed earnings and calculate your Class 4 NICs each year.


What Happens If We Don’t Pay Class 4 National Insurance in the UK?

Class 4 National Insurance Contributions (NICs) are a vital part of the UK tax system, particularly for self-employed individuals. These contributions are crucial for maintaining eligibility for certain state benefits, including the State Pension. Failing to pay Class 4 NICs can have several implications.


Overview of Class 4 NICs


  • Target Group: Class 4 NICs are paid by self-employed individuals earning above a certain profit threshold.

  • Contribution Rates: As of the 2024-25 tax year, the rates are 8% on profits between the Lower Profits Limit (£12,570) and Upper Profits Limit (£50,270), and 2% on profits above this upper threshold.


Consequences of Non-Payment


Loss of State Benefits

  • Non-payment can impact your entitlement to certain state benefits. While Class 4 NICs do not count towards the State Pension or other contributory benefits directly, they are often indicative of your self-employment status and income levels, which can affect your overall National Insurance record.

Reduced State Pension

  • A full State Pension requires 35 years of qualifying National Insurance contributions. Failure to pay Class 4 NICs could result in gaps in your NI record, potentially reducing the amount you're entitled to upon retirement.

Interest and Penalties

  • HM Revenue & Customs (HMRC) may charge interest on late payments and impose penalties for non-payment. These penalties can increase over time, adding a significant financial burden.

Increased Scrutiny from HMRC

  • Consistent non-payment or late payment can attract increased scrutiny from HMRC, potentially leading to audits or investigations. This scrutiny can be time-consuming and stressful.

Impact on Credit Ratings

  • Unpaid taxes, including NICs, may affect your credit rating. This can have long-term consequences, such as difficulty obtaining loans or mortgages.

Difficulty in Accessing Loans or Mortgages

  • Lenders often require proof of income, which includes a record of NIC payments for self-employed individuals. Non-payment could hinder your ability to secure financial products.

Legal Proceedings

  • In extreme cases, consistent non-payment of Class 4 NICs could lead to legal action by HMRC, including court proceedings.


Mitigating the Risk


Understanding Your Obligations

  • Stay informed about your NIC obligations, including the thresholds and rates for Class 4 NICs. This awareness is crucial for effective financial planning.

Maintaining Accurate Records

  • Keep accurate records of your earnings and expenses. This helps in calculating your correct NICs and reduces the likelihood of errors.

Seek Professional Advice

  • If you’re uncertain about your NICs payments, consult a tax professional. They can provide tailored advice based on your specific circumstances.

Making Voluntary Contributions

  • If you have low earnings or take a career break, consider making voluntary Class 2 or Class 3 NICs to avoid gaps in your NI record.

Engage with HMRC

  • If you’re struggling to pay your NICs, contact HMRC. They can provide guidance and may offer payment plans to help manage your tax liabilities.

Regular Review of Finances

  • Regularly review your financial situation to ensure you’re setting aside enough to cover your tax obligations, including Class 4 NICs.


Non-payment of Class 4 National Insurance Contributions can have significant and long-lasting effects on an individual's financial health and entitlement to state benefits in the UK. It's crucial for self-employed individuals to understand their NIC obligations and take proactive steps to ensure compliance. This approach not only safeguards against potential penalties and legal issues but also ensures a more stable financial future, particularly regarding entitlements like the State Pension.


At What Age Do You Stop Paying Class 4 National Insurance?

The age at which you stop paying Class 4 National Insurance Contributions (NICs) in the UK depends on your current state pension age and the number of NICs you have paid in the past.


In the UK, the state pension age is currently 67 years old and is due to increase to 68 years old between 2037 and 2039. If you reach state pension age, you will no longer be required to pay Class 4 NICs, even if you continue to work as a self-employed individual.


It is important to note that even if you reach state pension age, you may still be required to pay Class 2 NICs if you continue to work as a self-employed individual and earn above the Lower Earnings Limit, which is currently £184 per week.


Can We Claim Back Class 4 National Insurance?

Class 4 NICs are not refundable once they have been paid. It is not possible to claim back Class 4 National Insurance Contributions (NICs) once they have been paid in the UK. Class 4 NICs are a form of tax that is payable by self-employed individuals and are used to fund the state pension and other benefits, as well as the National Health Service (NHS) and other public services.


However, it is important to make sure that you only pay the correct amount of Class 4 NICs each year, based on your self-employed earnings and allowable expenses. If you overpay Class 4 NICs, you may be able to claim a refund by contacting HM Revenue and Customs (HMRC).


How Can a Tax Accountant Help You With Class 4 National Insurance in the UK?

In the complex landscape of UK tax regulations, a tax accountant plays a pivotal role, especially when it comes to understanding and managing Class 4 National Insurance Contributions (NICs) for self-employed individuals. Engaging a tax accountant can provide numerous benefits, ensuring compliance, optimizing tax liabilities, and offering peace of mind.

The Latest Updates on Class 4 National Insurance in the UK

The UK government has recently announced significant changes to the National Insurance system, which will come into effect in 2024. These changes are part of a broader effort to simplify the tax system and provide tax relief to working individuals. Here's a detailed overview of the latest updates:


Reduction in Class 1 and Class 4 National Insurance Contributions (NICs)

  • Class 1 NICs: The main rate of Employee National Insurance (Class 1 NICs) will be cut by 2 percentage points, from 12% to 10%, starting from 6 January 2024. This reduction is expected to benefit 27 million workers, decreasing the combined tax rate for employees paying the basic rate of tax from 32% to 30%​.

  • Class 4 NICs: For the self-employed, the main rate of Class 4 NICs will be reduced by 1 percentage point, from 9% to 8%, effective from 6 April 2024. This measure aims to simplify the tax system for self-employed individuals and provide them with tax relief​​​​​.


Abolishment of Class 2 National Insurance Contributions

  • From 6 April 2024, self-employed people with profits above £12,570 will no longer be required to pay Class 2 NICs. However, they will continue to have access to contributory benefits, including the State Pension​​​.

  • Those with profits between £6,725 and £12,570 will continue to receive access to contributory benefits through a National Insurance credit without paying NICs, as they do currently​.

  • Individuals with profits under £6,725, and others who pay Class 2 NICs voluntarily to access contributory benefits including the State Pension, will still be able to do so. The weekly rate they pay will be frozen at £3.45 for the tax year 2024-25, rather than rising by CPI to £3.70​​​.


Impact on Different Income Groups

  • The reduction in NICs rates is expected to benefit a wide range of workers, from nurses and teachers to police officers and self-employed individuals such as plumbers. For example, an average full-time nurse on £38,900 will receive an annual gain of over £520, and a typical self-employed plumber on £34,400 will be £410 better off as a result of these cuts​.

  • A family with two earners on average earnings of £35,404 will be £900 better off due to these changes​.


Additional Considerations

  • Employers need to update their payroll systems to reflect these changes. If they cannot amend their systems in time for the January change, they will be able to reimburse any overpayment of NICs to employees in subsequent months​.

  • The Lower Earnings Limit, which is the point at which employees start to receive NI credits, has been frozen at £6,396. This move supports low-income working individuals by maintaining their access to NICs credits without having to pay NICs​.
