What is CF83 Form?

Updated: Dec 29, 2023

The CF83 form is a form provided by HMRC that is used to request a Certificate of Residence for individuals. The Certificate of Residence is a document that confirms an individual's residency status in the UK for tax purposes. The Certificate of Residence is often required by foreign tax authorities when an individual has income or assets in the UK.


In other words, the form that you can use to pay the voluntary national insurance contributions of Class 2 and Class 3 (NICs) while working in another country is called the CF83 Form. The CF83 form is a vital document for UK nationals residing abroad, particularly concerning their National Insurance contributions. This form plays a key role in managing financial responsibilities and entitlements tied to the UK's social security system, including the State Pension. Understanding the CF83 form is crucial for UK expatriates and non-residents to ensure they remain compliant with UK regulations and secure their future financial benefits.

Understanding National Insurance Classes and Their Impact


Overview of National Insurance Classes

Understanding the various classes of National Insurance (NI) contributions is essential for UK taxpayers, especially those using the CF83 form to maintain their eligibility for UK benefits while living abroad. The class of NI contribution an individual makes depends largely on their employment status and income level.


Class 1 National Insurance

  • Who Pays: This class is for employees under the State Pension age earning more than £242 a week from one job. These contributions are automatically deducted by employers.

  • Rates: The rates vary based on the employee’s earnings and National Insurance category letter. For instance, category A earners pay nothing on the first £242, 12% on earnings between £242.01 and £967, and 2% on earnings above £967 weekly.


Class 1A and 1B National Insurance

  • Who Pays: These classes are paid by employers directly on their employees' expenses or benefits.

  • Rates: The rate for expenses and benefits is 13.8% from 6 April 2023 to 5 April 2024. Employers also pay Class 1A on some lump sum payments, such as redundancy payments.


Class 2 National Insurance

  • Who Pays: This class is for self-employed individuals earning profits of £12,570 or more a year.

  • Purpose: This class is particularly relevant for self-employed individuals who need to maintain their National Insurance record for future benefit entitlements.


Class 3 National Insurance (Voluntary Contributions)

  • Who Pays: Voluntary contributions can be made by anyone looking to fill or avoid gaps in their National Insurance record.

  • Relevance to CF83 Form: This class is especially significant for UK expatriates using the CF83 form. By making Class 3 contributions, they can maintain their NI record, ensuring eligibility for the State Pension and other benefits.


Class 4 National Insurance

  • Who Pays: This class applies to self-employed individuals earning profits of £12,570 or more a year.

  • Difference from Class 2: While similar to Class 2, Class 4 contributions are calculated differently and also play a part in maintaining a complete NI record for self-employed individuals.


Impact of National Insurance Contributions on UK Benefits

The contributions made to these different classes of National Insurance have a direct impact on an individual's entitlement to various UK social security benefits. Here's how:


  • State Pension: The State Pension is significantly affected by NI contributions. To qualify for the full State Pension, an individual must have a certain number of qualifying years on their NI record. Paying Class 2 or Class 3 NI contributions, especially through the CF83 form for those abroad, helps maintain this record.

  • Other Benefits: National Insurance contributions also affect eligibility for other benefits like Jobseeker's Allowance, Employment and Support Allowance, and Maternity Allowance. Each of these benefits has specific NI contribution criteria that must be met for eligibility.


Practical Implications for UK Expatriates

For UK nationals living abroad, the understanding of NI contribution classes and their practical implications is crucial. By correctly using the CF83 form to make voluntary Class 3 contributions, they can safeguard their entitlement to UK benefits. It's essential to:

  1. Determine Eligibility: Assess whether making voluntary contributions is beneficial based on your current NI record and future benefit needs.

  2. Understand the Rates: Familiarize yourself with the contribution rates and categories that apply to your situation.

  3. Timely Submission: Ensure that the CF83 form, along with any necessary documentation, is submitted to HMRC within the stipulated deadlines.
