National Insurance (NI) is a system of taxes paid by workers and employers in the UK to fund various state benefits, including the State Pension, Jobseeker’s Allowance, and other welfare programs. The contributions are categorized into different classes, each with specific rules regarding who pays them and how much. Understanding these classes is crucial for both employees and self-employed individuals as it affects their eligibility for benefits and the amount they need to contribute.
The classes of National Insurance contributions are primarily determined by an individual’s employment status and earnings. There are six main classes: Class 1, Class 1A, Class 1B, Class 2, Class 3, and Class 4. Each class has distinct characteristics that dictate how contributions are calculated and who is responsible for paying them.
| Class | Description |
|---|---|
| Class 1 | Paid by employees on earnings over £242 per week; employers also contribute. |
| Class 1A | Paid by employers on benefits provided to employees. |
| Class 1B | Paid by employers on expenses covered under a PAYE settlement agreement. |
| Class 2 | Flat rate contributions paid by self-employed individuals earning above £6,725 per year. |
| Class 3 | Voluntary contributions to fill gaps in NI records. |
| Class 4 | Paid by self-employed individuals on profits over £12,570 per year. |
Class 1 National Insurance Contributions
Class 1 contributions are the most common type of National Insurance paid by employees. These contributions are automatically deducted from an employee’s wages by their employer under the Pay As You Earn (PAYE) system.
- Eligibility: Employees under the State Pension age earning more than £242 per week must pay Class 1 contributions.
- Rates: Employees pay 8% on earnings between £242.01 and £967 per week and 2% on earnings above £967. If an employee earns less than £242, they do not pay any contributions but may still qualify for certain benefits.
Employers also contribute to Class 1 at a rate of 13.8% on employee earnings above £175 per week. This dual contribution system helps fund various state benefits that employees may access in the future.
Class 1A and Class 1B National Insurance Contributions
Classes 1A and 1B are specific to employers and relate to benefits provided to employees rather than direct salary payments.
- Class 1A: This class applies to benefits in kind provided to employees, such as company cars or health insurance. Employers pay Class 1A contributions at a rate of 13.8% on the value of these benefits.
- Class 1B: This class is relevant for employers who have a PAYE settlement agreement that covers employee expenses like travel or relocation costs. Similar to Class 1A, the rate is also 13.8%, but it simplifies reporting as these expenses do not need to be included in annual P11D forms.
Both classes ensure that employers contribute towards the social security system based on non-salary benefits provided to their employees.
Class 2 National Insurance Contributions
Class 2 contributions are specifically for self-employed individuals.
- Eligibility: Self-employed individuals must pay Class 2 if their profits exceed £6,725 per year.
- Rate: The contribution is a flat rate of £3.45 per week (or approximately £179 per year). This contribution counts towards entitlement for various state benefits like the State Pension.
From April 2024, changes in legislation will mean that most self-employed individuals will no longer be required to pay Class 2 NICs unless they choose to do so voluntarily to maintain their NI record.
Class 3 National Insurance Contributions
Class 3 contributions are voluntary payments made by individuals who wish to fill gaps in their National Insurance record.
- Purpose: These gaps may arise from periods of low income or unemployment.
- Rate: The current rate for Class 3 contributions is £17.45 per week for the tax year starting April 2024. Making these voluntary payments can help ensure eligibility for full State Pension benefits in retirement.
Individuals who are not working or have low earnings can opt for this class to enhance their future benefit entitlements.
Class 4 National Insurance Contributions
Class 4 contributions apply only to self-employed individuals with higher profits.
- Eligibility: Self-employed individuals must pay Class 4 if their profits exceed £12,570 annually.
- Rates: For profits between £12,570 and £50,270, the rate is 9%, while profits over £50,270 are taxed at a reduced rate of 2%.
Unlike Class 2 contributions, Class 4 does not count towards entitlement for certain state benefits but is still a crucial part of the overall NI framework for self-employed individuals.
