SolvedCH154200 | Penalties for Failure to Pay on Time: Rules for specific taxes: Registered Pension Scheme (RPS): Penalties: Assessments in absence of a return, amendments and corrections
From HM Revenue & Customs · Compliance Handbook
A person is liable to a penalty where they pay late an amount of income tax under the Registered Pension Scheme (RPS) that results from
HMRC issuing an assessment in the absence of a return, or
the person amending their return to correct an inaccuracy.
See below for what the penalty date is for each of these.
Assessment made in the absence of a return
Where we have issued an assessment in the absence of a return for a period, the penalty date is 31 days after the due date that would have applied if the income tax had been shown on a timely return for that period.
Assessment, other than in absence of a return, and amendment or correction of a return
Where further tax is due and payable resulting from an assessment, amendment or correction of a return, the penalty date is 31 days after the due date for this further tax. The person is liable to an initial penalty of 5% of the amount unpaid at the penalty date.
Note that if a person makes an amendment or correction to a return, this may indicate that the original return was incorrect and that they may be liable to an inaccuracy penalty under Schedule 24 FA07.
