“(1) A penalty is payable by a person (P) where– (a) P gives HMRC a document of a kind listed in the Table below, and (b) Conditions 1 and 2 are satisfied. (2) Condition 1 is that the document contains an inaccuracy which amounts to, or leads to– (a) an understatement of a liability to tax, (b) a false or inflated statement of a loss, or (c) a false or inflated claim to repayment of tax. (3) Condition 2 is that the inaccuracy was careless (within the meaning of paragraph 3 ) or deliberate on P's part. (4) Where a document contains more than one inaccuracy, a penalty is payable for each inaccuracy.”
“(1) For the purposes of a penalty under paragraph 1 , inaccuracy in a document given by P to HMRC is– ‘careless’ if the inaccuracy is due to failure by P to take reasonable care, ‘deliberate but not concealed’ if the inaccuracy is deliberate on P’s part but P does not make arrangements to conceal it, and ‘deliberate and concealed’ if the inaccuracy is deliberate on P’s part and P makes arrangements to conceal it (for example, by submitting false evidence in support of an inaccurate figure)”
“The potential lost revenue” in respect of an inaccuracy in a document (including an inaccuracy attributable to a supply of false information or withholding of information) or a failure to notify an under-assessment is the additional amount due or payable in respect of tax as a result of correcting the inaccuracy or assessment.”
“18(1) P is liable under paragraph 1(1)(a) where a document which contains a careless inaccuracy (within the meaning of paragraph 3) is given to HMRC on P's behalf. 18(2) In paragraph 2(1)(b) and (2)(a) a reference to P includes a reference to a person who acts on P's behalf in relation to tax. 18(3) Despite sub-paragraphs (1) and (2), P is not liable to a penalty under paragraph 1 or 2 in respect of anything done or omitted by P's agent where P satisfies HMRC that P took reasonable care to avoid the inaccuracy (in relation to paragraph 1) or unreasonable failure (in relation to paragraph 2).”
“ 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. The test of deliberate inaccuracy should be contrasted with that of careless inaccuracy. A careless inaccuracy occurs due to the failure by the taxpayer to take reasonable care (see paragraph 3(1)(a) of Schedule 24Finance Act 2007 and Harding v HMRC[2013] UKUT 575 (TCC) at [37]).”
“we consider that the term “deliberate inaccuracy on a person’s part can extend beyond this. Our view is that, depending on the precise circumstances, an inaccuracy may also be held to be deliberate where it is found that the person consciously or intentionally chose not to find out the correct position, in particular, where the circumstances are such that the person knew that he should do so. A person cannot simply escape liability by claiming complete ignorance where the person clearly knew that he should have taken steps to ascertain the position. We view the case where a person makes such a conscious choice not to take such steps with the result that an inaccuracy occurs, as no less of a “deliberate inaccuracy” on that person’s part than making the inaccuracy with full knowledge of the inaccuracy.”
