Social security benefits provide exactly that – security in social situations where you can’t work, for example due to illness or injury.
If you’re paid by a Guernsey-based employer you will be entitled to claim social security benefits (in the unlikely event that you need them) because you will pay social security contributions out of your wages (check out the article on taxes to find out how and how much).
However, if you’re paid by a UK-based umbrella company you do not need to pay Social Security contributions as you’ll more than likely be paying National Insurance to HMRC.
To apply for a social security number, all you need to do is head to the gov.gg website, download the Registration Form, complete your details and deliver it either by post or in person to the States of Guernsey.
