Failure to furnish information triggers penal fines for omission or wilful falsification, with additional daily penalties for continuing defaults. Failure to furnish required information or returns without reasonable cause, or wilfully furnishing information or returns known to be false, is a punishable offence carrying a monetary fine and, where the offence continues, additional daily penalties capped by an overall limit; the provision treats continued non-compliance as a continuing offence attracting daily liability after the first day.
