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 (sign in to or set up a Government gateway account)
  • fill in form on-screen, print and post it to HM Revenue and Customs (HMRC)

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.

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 can’t save a partly completed form so gather all your information together before you start to fill it in.
