Employers must pay Class 1A NICs for 2024–25 benefits by 19 July (post) or 22 July (electronic). These apply to perks like company cars and private health cover—late payment risks penalties from HMRC.

Class 1A NICs are payable by employers on the value of most taxable benefits offered to employees and directors, including company cars and private medical insurance. They are also due on any portion of termination payments exceeding £30,000, provided that Class 1 NICs have not already been applied.

To ensure the payment is correctly allocated, employers should use their Accounts Office reference number as the payment reference and clearly indicate the relevant tax year and month. It is important to note that Class 1A NICs paid in July always relate to the previous tax year.

There are three key dates employers must remember for the 2024–25 Class 1A NICs. Forms P11D and P11D(b) must be submitted by 6 July 2025. Postal cheque payments must reach HMRC by 19 July 2025, and electronic payments must clear into HMRC’s bank account by 22 July 2025.

These contributions generally apply to benefits provided to company directors, employees, individuals in controlling positions, and their family or household members.

Employers must pay Class 1A NICs on 2024–25 benefits by 19 July (22 July if paying electronically). Avoid penalties by meeting deadlines and using correct references.

Employers are reminded of the upcoming Class 1A National Insurance contributions (NICs) deadline, which applies to most benefits in kind provided to employees during the 2024–25 tax year. These contributions must be paid by 19 July 2025 (or 22 July 2025 if paying electronically) to avoid penalties.

Class 1A NICs are payable by employers on the value of most taxable benefits provided to employees and directors, such as company cars and private medical insurance. They are also due on the portion of termination payments exceeding £30,000, where Class 1 NICs haven’t already been applied.

To ensure payment is correctly allocated, employers must use their Accounts Office reference number as the payment reference and indicate clearly which tax year and month the payment relates to. Note that Class 1A NICs paid in July will always relate to the previous tax year.

There are three key dates to keep in mind for 2024–25 Class 1A NICs:

• 6 July 2025 – Submission deadline for forms P11D and P11D(b) (‘Return of Class 1A National Insurance contributions due’)
• 19 July 2025 – Deadline for postal cheque payments to be received by HMRC
• 22 July 2025 – Deadline for electronic payments to clear into HMRC’s bank account

These contributions are typically due on benefits provided to:

• Company directors and those in controlling positions
• Employees
• Family members or household members of the above

A reminder that increases to the rate of National Insurance contributions (NICs) that are paid by employers came into effect on 6 April 2025. The main rate of secondary Class 1 NICs has increased to 15% (from 13.8%). This applies to earnings above the secondary threshold for employees. In addition, both Class 1A and Class 1B employer NIC rates—typically applied to benefits-in-kind and PAYE settlement agreements—have also increased in line with the main secondary rate.

The Class 1 NICs secondary threshold, the level at which employers start to pay NICs, has been reduced to £5,000 (from £9,100) per year. This change took effect on 6 April 2025 and will last until 5 April 2028. After that, the threshold will be adjusted annually based on the Consumer Price Index (CPI).

To help mitigate the impact of these increases—particularly for smaller employers—the government has expanded the Employment Allowance. From April 2025, the allowance has risen from £5,000 to £10,500. The previous eligibility restriction, which limited the allowance to businesses with less than £100,000 in annual employer NIC liabilities, has now been removed. This change means more employers will now qualify for the allowance.

Self-employed individuals earning £12,570 or more annually must pay Class 4 National Insurance Contributions (NICs). For 2024-25, rates are 6% on profits up to £50,270 and 2% above this. Certain groups are exempt, and voluntary Class 2 NICs may be beneficial.

Class 4 NIC rates for the tax year 2024-25 are 6% for chargeable profits between £12,570 and £50,270 plus 2% on any profits over £50,270. There are no changes to these rates for 2025-26.

A number of categories of people are exempt from paying Class 4 NICs, these include:

• People under the age of 16 at the beginning of the year of assessment.
• People over State pension age at the beginning of the year of assessment. A person who attains State pension age during the course of the year of assessment remains liable for Class 4 NICs for the whole of that year.
• People receiving profits in their capacity as a trustee, executor or administrator of a person liable to tax under ITTOIA2005/S8.

The mandatory payment of Class 2 National Insurance Contributions (NICs) for the self-employed was abolished effective from 6 April 2024. It can be beneficial for some self-employed people who do not pay NICs through self-assessment to make voluntarily Class 2 NICs. This can help them to access certain contributory benefits including the State Pension. It is important to confirm that this would be beneficial before making any voluntary payment. The current weekly rate for making voluntary Class 2 NICs is £3.45 and is increasing to £3.50 in 2025-26.

Most self-employed individuals pay Class 2 and Class 4 NICs through self-assessment. Certain self-employed roles, such as examiners, moderators, invigilators, and ministers of religion without a salary do not pay National Insurance through self-assessment but may want to pay voluntary contributions.

Even if you have never been employed, you might have been eligible for NI credits without realising it. For example, if you have been a carer for a sick or disabled person for more than 20 hours a week, you could have claimed Carer's Credit. Similarly, if you have been receiving certain benefits, such as Jobseeker's Allowance or Employment and Support Allowance, you might have automatically received NI credits.

It's a good idea to review your personal history to see if there are any periods where you might have been eligible for NI credits. If you identify such periods, you can contact the HM Revenue and Customs (HMRC) to see if your NI record can be updated accordingly.

Paying Voluntary Contributions

If you are below the State Pension age and have gaps in your NI record, you can choose to pay voluntary contributions to boost your State Pension entitlement. This can be particularly beneficial if you have some qualifying years but not enough to reach the 10-year minimum.

Before deciding to pay voluntary contributions, it's important to:

• Check Your National Insurance Record: This will show you any gaps in your contributions and how they affect your State Pension forecast.
• Evaluate the Cost: Voluntary contributions come at a cost, so you'll need to assess whether the potential increase in your State Pension is worth the expense.
• Consider Your Health and Life Expectancy: If you're in poor health, it might not be financially beneficial to make voluntary contributions.

You can find more information on paying voluntary NI contributions on the GOV.UK website.
