“(1) For the purposes of a penalty under paragraph 1, inaccuracy in a document given by P to HMRC is— … (b) “deliberate but not concealed” if the inaccuracy is deliberate on P's part but P does not make arrangements to conceal it…”
“(1) Where a penalty under paragraph 1 is payable by a company for a deliberate inaccuracy which was attributable to an officer of the company, the officer is liable to pay such portion of the penalty (which may be 100%) as HMRC may specify by written notice to the officer. (2) Sub-paragraph (1) does not allow HMRC to recover more than 100% of a penalty.
“In our view, a deliberate inaccuracy occurs when a taxpayer knowingly provides HMRC with a document that contains an error with the intention that HMRC should rely upon it as an accurate document. This is a subjective test. The question is not whether a reasonable taxpayer might have made the same error or even whether this taxpayer failed to take all reasonable steps to ensure that the return was accurate. It is a question of the knowledge and intention of the particular taxpayer at the time.”
