“(1) P is liable to a penalty, in relation to each tax, of an amount determined by reference to- (a) the number of defaults that P has made during the tax year (see sub-paragraphs (2) and (3)), and (b) the amount of that tax comprised in the total of those defaults (see sub-paragraphs (4) to (7)). (2) For the purposes of this paragraph, P makes a default when P fails to make one of the following payments (or to pay an amount comprising two or more of those payments) in full on or before the date on which it becomes due and payable- (a) a payment under PAYE regulations; (b) a payment of earnings-related contributions within the meaning of theSocial Security (Contributions) Regulations 2001 (SI 2001/1004); … (3) But the first failure during a tax year to make one of those payments (or to pay an amount comprising two or more of those payments) does not count as a default for that tax year. (4) … (5) If P makes 4, 5 or 6 defaults during the tax year, the amount of the penalty is 2% of the amount of the tax comprised in the total of those defaults. (6) If P makes 7, 8 or 9 defaults during the tax year, the amount of the penalty is 3% of the amount of the tax comprised in the total of those defaults. … (8) For the purposes of this paragraph- (a) the amount of a tax comprised in a default is the amount of that tax comprised in the payment which P fails to make; (b) a default counts for the purposes of sub-paragraphs (4) to (7) even if it is remedied before the end of the tax year. …”
“If any amount of tax is unpaid after the end of the period of 6 months beginning with the penalty date, P is liable to a penalty of 5% of that amount”
“(1) If P satisfies HMRC or (on appeal) the First-tier Tribunal or Upper Tribunal that there is a reasonable excuse for a failure to make a payment- (a) liability to a penalty under any paragraph of this Schedule does not arise in relation to that failure, and (b) the failure does not count as a default for the purposes of paragraphs 6… (2) For the purposes of sub-paragraph (1)- (a) an insufficiency of funds is not a reasonable excuse unless attributable to events outside P's control, (b) where P relies on any other person to do anything, that is not a reasonable excuse unless P took reasonable care to avoid the failure, and (c) where P had a reasonable excuse for the failure but the excuse has ceased, P is to be treated as having continued to have the excuse if the failure is remedied without unreasonable delay after the excuse ceased.”
“(1) If HMRC think it right because of special circumstances, they may reduce a penalty under any paragraph of this Schedule. (2) In sub-paragraph (1) "special circumstances" does not include- (a) ability to pay, or (b) the fact that a potential loss of revenue from one taxpayer is balanced by a potential over-payment by another. (3) In sub-paragraph (1) the reference to reducing a penalty includes a reference to- (a) staying a penalty, and (b) agreeing a compromise in relation to proceedings for a penalty.”
“(1) On an appeal under paragraph 13(1) that is notified to the tribunal, the tribunal may affirm or cancel HMRC's decision. (2) On an appeal under paragraph 13(2) that is notified to the tribunal, the tribunal may- (a) affirm HMRC's decision, or (b) substitute for HMRC's decision another decision that HMRC had power to make. (3) If the tribunal substitutes its decision for HMRC's, the tribunal may rely on paragraph 9- (a) to the same extent as HMRC (which may mean applying the same percentage reduction as HMRC to a different starting point), or (b) to a different extent, but only if the tribunal thinks that HMRC's decision in respect of the application of paragraph 9 was flawed. (4) In sub-paragraph (3)(b) "flawed" means flawed when considered in the light of the principles applicable in proceedings for judicial review. (5) In this paragraph "tribunal" means the First-tier Tribunal...”
“…if the exercise of reasonable foresight and of due diligence and a proper regard for the fact that the tax would become due on a particular date would not have avoided the insufficiency of funds which led to the default, then the taxpayer may well have a reasonable excuse for non-payment, but that excuse will be exhausted by the date on which such foresight, diligence and regard would have overcome the insufficiency of funds.”
“The test of whether or not there is a reasonable excuse is an objective one. In my judgment it is an objective test in this sense. One must ask oneself:- was what the taxpayer did a reasonable thing for a responsible trader 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?”
