Details

If you normally work in 2 or more countries in the European Economic Area (EEA) you, or your agent can:

  • use the online service
  • fill in form on-screen, print and post it to HMRC

To enquire online, you need a Government Gateway user ID and password. If you do not have a user ID, you can create one when you enquire.

This allows HMRC to determine which country’s social security legislation will apply.

If you use the online form, you’ll get a reference number to use to track the progress of your form.

Email HMRC to ask for this form in Welsh (Cymraeg).

Before you start using the postal form

If you’re using an older browser, for example Internet Explorer 8, you’ll need to update it or use a different browser. Find out more about browsers.

You’ll need to fill in the postal form fully before you can print it. You cannot save a partly completed form so gather all your information together before you start to fill it in.
