“According to the Default Surcharge-Review Conclusion Letter sent by HMRC “we will only cancel a default surcharge assessment if certain conditions apply … the conditions are that … there is a reasonable excuse for the payment and/or return being late”
“The test of whether or not there is reasonable excuse is an objective one. In my judgement it is an objective test in this sense. One must ask oneself: was what the taxpayer did a reasonable thing for a responsible taxpayer conscious of and intending to comply with his obligations regarding tax, but having the experience and other relevant attributes of the taxpayer and placed in the situation that the taxpayer found himself at the relevant time, a reasonable thing to do?”
