Regulation 11 Non-standard accounting periods
Where a bookmaker’s accounting periods are specified under regulation 9 or 10 above and he—
is convicted of an offence under paragraph 13(3) of Schedule 1 to the Act,
fails to furnish a return by the due date in accordance with regulation 5 above, or
fails to pay duty due from him in accordance with regulation 6 above, each calendar month following the accounting period in which he was convicted or in respect of which that failure occurred is an accounting period.
If—
a bookmaker’s accounting periods are specified under regulation 10 above, and
in the twelve months immediately preceding the end of any three-month accounting period the aggregate of the amounts that were due to that bookmaker in respect of bets of any class exceeded £750,000,
his accounting periods in respect of bets other than financial spread bets cease to be those specified under regulation 10 above; and each calendar month following the end of that three-month accounting period is an accounting period.
For the purposes of—
regulations 9(3)(c) and 10(3)(c) above, and
paragraph (1)(c) of this regulation,
if the Commissioners have agreed to accept late payment of any duty that duty is not to be treated as outstanding from a bookmaker unless he fails to pay it by the time for payment agreed with the Commissioners.
