CH29860 | Data gathering: Penalties: Other penalty issues: Overview
From HM Revenue & Customs · Compliance Handbook
A penalty assessment for failing to comply with a data-holder notice is enforced as if it were an assessment of income tax.
The Treasury has the power to change the amount of the
initial fixed penalty
daily default penalty
increased daily default penalty, and
penalty for inaccurate information or documents.
Any changes to these amounts will be made by regulations.
We cannot charge a penalty for failing to comply with a data-holder notice if the data-holder has been convicted of an offence connected to the failure.
