What is CF83 Form?

Updated: Apr 4

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.

What are National Insurance Contributions (NICS)?

Your NICs contribute to that pot allocated to state pensions and a few Social Security benefits. The amount of the state pension, as well as bereavement and disability benefits as well as certain social security benefits, is contingent on the amount you've paid during your career. There are six different types of NICs and your type of employment determines the amount you have to pay.

National Insurance If you Travel Abroad

It is possible for UK National Insurance while you work abroad, based on the location you work and how long. You'll ensure your State Pension as well as the right to other allowances and benefits if you continue to pay National Insurance while you are away.

Working within the EEA

If you're employed in a country that is part of the EU or EEA or Switzerland the requirements to do it are based on the circumstances.

If You Work for an Employer in the EEA

The norm is that you contribute to social security for your EEA the country that you work in, rather than National Insurance. This is the case for:

you'll be covered by the social security laws of that country and could be eligible for benefits in the country.

the benefits you are entitled to in the UK (for example, the State Pension) could be affected since there could be gaps in your National Insurance contributions

There is a chance that you can still get low or free medical care within the nation if you are employed.

You may be Entitled to Some Kind of National Insurance Reimbursement

If you're a worker outside of the UK and you pay Class 1 NICs, then you might be entitled to an insurance rebate for national coverage. Find out more information about this in our guide on Form the CA307 request for national insurance.

Why Should I Choose a Payment of NICs Within the UK Even Though I don't Reside There?

Many people opt to continue paying NICs while working overseas to secure their entitlement to the full state pension, Social Security, and Bereavement advantages.

Do these Rules Apply to Every UK Taxpayer Working in other Countries?

It depends on the length of time your job abroad, the country you're moving to, and the kind of work you are employed in. There are different regulations for those who are in the Armed Services and their families when they are stationed abroad, mariners, and civil aviation crews.

If you plan to work on the Isle of Man or Northern Ireland or Northern Ireland, the social security payments are connected and you do not have to sign up to contribute on your own. Also, if you're moving to a nation that has a social safety agreement in place with the UK or a European Economic Area country.

What Kind of NICs Must I Pay for?

The first two weeks you work abroad then you are required to make payments for Class I NICs if you were already a UK resident prior to the day the time you began your work abroad or you are deemed to be a 'normal resident in the UK or if the employer has office space in Britain. If you choose to contribute your money in a voluntary manner you are able to pay Class 2 or Class 3 NICs.

Class 2 NICs

This amount in National Insurance is for those who work for themselves or are self-employed in another country and who have paid NICs of Class 1 for the first 52 weeks of employment. The criteria for eligibility are that you are a UK taxpayer before you started your work in another country, that you have paid NICs to a certain amount during the 3 years preceding your leaving the UK, or had a job in the UK prior to making the move for 3 consecutive years. Class 2 NICs are part of state pensions bereavement benefits, state pensions, and other benefits of the state (such as Employment and Support Allowance).

Class 3 NICs

The contribution amount you pay is the costs that you receive from your government pension as well as your spouse's right to bereavement benefits (civil and married). The NICs are payable to you regardless of where you reside. You are eligible to be able to pay Class 3 National NICs only if you satisfy the following requirements you have been paying Class I NICs during the initial 52 weeks of overseas work, you've paid a certain amount in NICs during the 3 years prior to your move abroad or lived for the UK for three consecutive years prior to working in another country. (Time that you spent working in Turkey or another EEA country is counted toward this time frame.)
