"Suspension” (1) HMRC may suspend all or part of a penalty for a careless inaccuracy under paragraph 1 by notice in writing to P. (2) A notice must specify (a) what part of the penalty is to be suspended, (b) a period of suspension not exceeding two years, and (c) conditions of suspension to be complied with by P. (3) HMRC may suspend all or part of a penalty only if compliance with a condition of suspension would help P to avoid becoming liable to further penalties under paragraph 1 for careless inaccuracy. (4) A condition of suspension may specify (a) action to be taken, and (b) a period within which it must be taken. (5) On the expiry of the period of suspension (a) if P satisfies HMRC that the conditions of suspension have been complied with, the suspended penalty or part is cancelled, and (b) otherwise, the suspended penalty or part becomes payable. (6) If, during the period of suspension of all or part of a penalty under paragraph 1, P becomes liable for another penalty under that paragraph, the suspended penalty or part becomes payable. The relevant extracts from the HMRC Compliance Handbook ("
"In certain circumstances it will not be possible to set suspension conditions to avoid future penalties. This may be because of the nature of the tax that the penalties related to, or because of the capacity in which the person has incurred the penalties. For example - 1. Penalties for a careless inaccuracy in an IHT account for a deceased person will not be suitable for suspension in most cases because of the one-off nature of the tax. 2. Jesse incurred a penalty for careless inaccuracy in his return of business profits. However, he retired from business during the course of the compliance check. Suspending the penalty will not help Jesse avoid a similar penalty in the future and so the penalty will be chargeable in full."
"Penalties will not be suspended where the circumstances mean that the inaccuracy is a one off. For instance an inaccuracy in an Inheritance Tax account for a deceased person, see CH 83130. However, certain types of settlement may have a continuing requirement to make returns. This means that it may be possible to set suspension conditions."
"Penalties for inaccuracies that are not likely to recur, whether because of the nature of the tax or the nature of the understatement, are generally not suitable for suspension because it is not usually possible to set conditions that will avoid careless inaccuracies in the future, or during a period of suspension. For example - A tennis club sells its land to the Local Authority for a road widening scheme. The authority provides land elsewhere to rent to enable the club to continue its activities. The capital gain was omitted from the return and it is accepted that a penalty is due for a careless inaccuracy. As the club is unlikely to have any capital gains in the future there is no condition that could be set to avoid a similar inaccuracy arising in the future. The nature of the tax in question may mean that suspension conditions cannot be set. For instance, Inheritance Tax penalties are not suitable for suspension because of the one-off nature of the tax, see CH 83150. The conditions you set must help the future compliance of the person acting in the same capacity. For instance, if the Administrator of an estate only ever needed to make a single return there would be no condition that you could set to avoid a future inaccuracy. However, if the estate needed to make annual returns the Administrator would have an ongoing role in the same capacity. You would then be able to consider whether suspension conditions could be set."
