Working or claiming benefits in the UK? You may need to apply for a National Insurance number first. If you do not already have one, your NI number is essential for tracking tax, National Insurance contributions and accessing certain government services. While most UK residents receive their number at age 16, newcomers or those starting work later in life may need to apply. It takes around four weeks to process after proving your identity, but you can still start work or claim some benefits while you wait.

According to HMRC guidance, you can apply for a National Insurance number if you:

• live in the UK,
• have the legal right to work in the UK, and
• are working, looking for work, or have a job offer.

You can still start work without an NI number, as long as you can prove your right to work in the UK. Similarly, you can apply for benefits or a student loan without an NI number, though you may be asked to provide one later if required.

Most teenagers living in the UK receive a letter shortly before their 16th birthday confirming their NI number. This letter is important and should be kept safe. Your NI number is unique and stays the same for life, even if your name, address or nationality changes. If you lose your NI number, you can find it on official documents like payslips, P60s or via your personal tax account.

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.

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.

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.
