“103Time limits for penalties
(1)Subject to subsection (2) below, where the amount of a penalty is to be ascertained by reference to tax payable by a person for any period, the penalty may be determined by an officer of the Board, or proceedings for the penalty may be commenced before the Commissioners or a court—
