SolvedCH112500 | Offshore matters: failure to file on time penalties: information falls into more than one category
From HM Revenue & Customs · Compliance Handbook
Amount of penalties involving an offshore matter
If the information falls into more than one category
the person’s failure to make the return is treated as if it were separate failures for each category of information, and
for each category, the liability to tax which would have been shown in the return is taken to be such share of the liability to tax which would have been shown in the return as is just and reasonable.
For example, if the information involves an income source or an asset that is present in territory A and territory B but territory A is in category 1 while territory B is in category 3, you should
treat the information as if it were two separate failures, one for territory A, the other for territory B,
place the failure for territory A in category 1 and the failure for territory B in category 3, and
share the total tax liability from the return between each of the two failures. You will need to look at the facts of the situation to do this in a just and reasonable way.
