SAOG21600 | Assessing a penalty: what a notice of a penalty assessment must include
From HM Revenue & Customs · Senior Accounting Officer Guidance
The notice of a penalty assessment issued to a Senior Accounting Officer (SAO) or company must be by letter and include
the unique tax reference (UTR) of the SAO or company (as appropriate)
the name of the company (for notification failure penalties)
the name of the SAO and company (for SAO personal penalties)
the address of the SAO or company (as appropriate). (For the SAO usually the private address. For the company the assessment letter should be addressed to the Company Secretary)
the date of the assessment
the amount of the penalty
the financial year to which the penalty relates
the legislation under which the penalty is assessed
the due date for payment, and
payment instructions, including HMRC’s accounting reference number - usually provided on a Proforma Payslip (PS2), see SAOG21500.
If there is no UTR for the SAO for example, where they are not a registered UK taxpayer, the pseudo reference number should be included in the penalty assessment to identify the person with the charge, see SAOG21500.
The notice of the penalty assessment must also explain the appeal and review rights available to the person, see ARTG2100+.
