CTSA: penalties for late returns: concessionary period: operation of

The application of the ESC/B46 set out at CTM94030 is an ‘all or nothing’ matter.

If you receive the return within the concessionary period, there is no question of charging a penalty, no matter what the reason for the delay.

When you receive the return after the end of the concessionary period, charge a penalty unless the company satisfies you that it:

  • has a reasonable excuse for not having delivered the return by the statutory filing date,


  • delivered it as soon thereafter as it reasonably could.

Equally, when you allow further time under TMA70/S118 (2) do not add the concessionary period to the further time.
