Suspending careless inaccuracy penalties can result in a Schedule 24 penalty ultimately falling away, but suspension is not available merely because the taxpayer asks for leniency or promises to be more careful. The purpose of suspension is to correct an identifiable weakness in records, systems or procedures that could otherwise cause a further careless inaccuracy.
The first issue is therefore not the amount of the penalty. It is whether a practical and measurable condition can be imposed that addresses the underlying reason the error occurred.
When suspending careless inaccuracy penalties is possible
Only penalties for careless inaccuracies can be considered for suspension. Deliberate inaccuracies cannot be suspended, nor can certain other penalty categories such as failures to take reasonable steps following an under-assessment.
The current rules governing suspension of careless penalties require suspension to be considered for every qualifying careless inaccuracy, but it is only appropriate where at least one specific condition can be set that would help prevent a further careless inaccuracy.
An isolated arithmetical mistake may therefore be difficult to suspend if there is no system weakness capable of correction. By contrast, recurring failure to reconcile bank transactions, maintain mileage records or identify private expenditure may lend itself to clear preventative conditions.
Suspending careless inaccuracy penalties requires SMART conditions
The conditions should be Specific, Measurable, Achievable, Realistic and Time bound.
It is not sufficient to require a taxpayer simply to “take more care” or “submit correct returns”. A useful condition addresses the actual process that failed.
If a company repeatedly failed to reconcile director loan transactions, a condition might require a documented quarterly reconciliation of the director’s loan account, supported by the relevant bank and expense records, with a year-end review before the Corporation Tax return is filed.
If a landlord omitted rental receipts because several bank accounts were being used, a condition might require all rental income to be recorded in one central schedule and reconciled quarterly to each letting statement and bank account.
The requirements for specific suspension conditions focus on improving the underlying system rather than repeating a legal requirement that already exists.
A generic condition requiring all relevant returns to be filed on time during the suspension period will normally apply in addition to the specific condition.
Not every careless error is suitable for suspension
Suspension is most effective where HMRC can identify how the same underlying weakness could generate another inaccurate return.
If an unusual one-off transaction was misunderstood but is unlikely ever to recur, there may be no meaningful preventative condition to impose. Conversely, an accounting-system weakness can remain suitable for suspension even where the precise transaction that exposed it was unusual.
HMRC must also consider likely future compliance. Previous behaviour, the quality of the taxpayer’s disclosure and whether deliberate inaccuracies were identified elsewhere in the same check can influence the decision.
The request for suspension should therefore explain what caused the error, what process is being changed and how that change will be evidenced.
The monitoring period should not automatically be two years
The maximum suspension period is normally 24 months, but the period should be no longer than necessary for the taxpayer to implement and demonstrate the required improvement.
The rules for setting the suspension period emphasise that 24 months should not be treated as a standard period and that shorter periods are appropriate where the corrective process can be implemented and tested sooner.
For a VAT error, several quarterly return cycles may provide evidence that a new control is functioning. For an annual Self Assessment problem, a longer period may be necessary to demonstrate that the revised process has worked through another return cycle.
Evidence should be retained throughout the suspension period
The taxpayer should preserve reconciliations, control sheets, internal procedures, software reports and correspondence showing that the conditions have actually been followed.
If the conditions are satisfied and no disqualifying further careless inaccuracy occurs, the suspended penalty can ultimately be cancelled. Failure to satisfy the conditions can cause the suspended amount to become payable.
Where a penalty arises during an HMRC compliance check, the suspension argument should be developed alongside the underlying behaviour analysis rather than raised as an afterthought. For broader penalty disputes, HMRC tax investigation advice should examine whether the conduct was genuinely careless before accepting that a penalty is due at all.
