The rule in plain words

A non-EEA branch can't write business via FPS

What to do if your return fails it

  1. 01Open the tables below and find the cells the rule reads.
  2. 02The check applies only when its first part holds in your return. When it does, the second part must hold too: fix the second part, or correct the first.
  3. 03It runs only when your filing indicators mark S.04.03 and S.04.04 as reported.
  4. 04This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.
