“The test is one of reasonableness. No higher (or lower) standard should be applied. The mere fact that something could have been done that has not been done does not of itself necessarily mean that individual’s conduct in failing to act in a particular way is to be regarded as unreasonable. It is a question of degree having regard to all the circumstances, including the particular circumstances of the individual taxpayer. There can be no universal rule; what might be considered a reasonable failure on the part of one taxpayer and one set of circumstances might be regarded as not unreasonable in the case of another whose circumstances are different.”
“85. The fact is that HMRC did publish guidance, which if followed, would have avoided the appellant making errors in CIS deductions. It is reasonable to have expected the appellant, given its size and frequency of CIS processing, to have read the guidance, have systems in place to monitor and respond to any change in guidance and to apply the rules based on this understanding. 86. Whether or not there are common misunderstandings within the industry as to the CIS Regulations, it would not be taking reasonable care simply to adopt the same and continued practice without first checking whether it was compliant. Where there is uncertainty a reasonable person can be expected to seek guidance from an appropriate source. The appellant engaged at least one member of staff to deal with the CIS aspect of the business and it should be expected that a reasonable and proportionate care would be taken to read, understand, and apply the requirements within the CIS Regulations. 87. In our view a prudent and reasonable business the size of the appellant with experience in engaging subcontractors would have been aware of the responsibilities and put into place adequate procedures to ensure compliance with CIS Regulations to avoid the errors the appellant made. 88. Therefore, we are not satisfied that the appellant has met Condition A under regulation 9(3). We are not satisfied it took reasonable care to comply with section 61 of the Act and the Regulations. We are not satisfied its failures to make the excess deductions for the purposes of the CIS Regulations were as a result of it taking reasonable care.”
