CTSA: group relief: simplified arrangements: authorising company

Regulation 5 SI1999/2975

The companies, which enter into the simplified arrangements along with the authorised company (CTM97660), are called the ‘authorising companies’. A company can be an authorising company if it is:

  • a member of the group (CTM97680), or
  • a company owned by a consortium of which a group company is a member (CTM80555).

The authorising company must:

  • be named in the application to set up the simplified arrangement (CTM97690), or
  • be treated as having joined the arrangement (CTM97700).

Companies with accounting periods which overlap, but do not correspond may enter into a simplified arrangement.

The authorising companies remain liable in respect of any incorrect claims or amended returns made under the arrangements, even though the authorised company makes them on their behalf.
