Apply for a certificate confirming an employee pays UK National Insurance when working abroad (CA3822)

You can use this form if you’re an employer, employee or an agent acting on behalf of an employer or employee.

Use this form for employees working temporarily in only one of the following:

• an EU country
• Gibraltar
• Iceland
• Liechtenstein
• Norway
• Switzerland

You cannot apply more than 12 months in advance.

Before you start

You must have confirmation from HMRC that your business is eligible to apply for a certificate. You need to make this check every 2 years.

You can ask HMRC to confirm your eligibility using form CA3821.

What you’ll need

You’ll need to know the following employee information:

• their country and place of birth
• if they’ve changed their name, you’ll need their previous one
• which nationalities they hold
• if they’ve previously been self-employed in the UK in the last 5 years, you’ll need the end-date of their self-employment

If you do not have this information, you may be unable to complete and submit form CA3822. Even if you are able to submit the form without the information, it may take us longer to process your application.

You might also need to check if the employee:

• has a husband, wife or partner who has an EU Settlement Scheme status
• holds a non-UK nationality they got before 1 January 2021
• holds a right to work in the UK — if they do, you’ll need to know what type of right to work they hold and if they held this right before 1 January 2021
• has a current right to reside in an EU country, Gibraltar, Iceland, Liechtenstein, Norway or Switzerland, if they do, you’ll need to know if they held this right before 1 January 2021
• has lived or worked in an EU country, Gibraltar, Iceland, Liechtenstein, Norway or Switzerland before 1 January 2021
• will be resident in an EU country, Gibraltar, Iceland, Liechtenstein, Norway or Switzerland, and if they have dependants living with them who also need healthcare cover — if so, you’ll need the following details for each dependant:
  • name
  • date of birth
  • their working status (if they are over 16 years old)

If you’re applying for a certificate for a period longer than allowed, you’ll need a statement signed by the employee. The signed statement should cover why the employee wants to continue paying UK National Insurance while working abroad and how it’s in their best interest.

If you’re an agent

If you’re an agent working on behalf of your client, your client needs to fill in an authorising your agent (64-8) form. Attach the completed form to your CA3822 application form.

If you’re applying for an extension to an existing certificate

You’ll need to know the date the existing certificate expires and any changes in the employee’s circumstances since the previous application. If the total time period for the existing certificate and the extension is longer than allowed, you’ll need a statement signed by the employee. The signed statement should cover why the employee wants to continue paying UK National Insurance while working abroad and how it’s in their best interest.
