This section is supplementary to the provisions of sections 73 and 74. It permits the Treasury by order to modify enactments to take account of the Scottish Parliament’s tax-varying power. In particular, such an order may exclude the effect of any tax-varying resolution in relation to certain enactments, or postpone the effect of such a resolution in relation to the operation of the PAYE system. Further provision about the making of subordinate legislation is to be found in sections 112 to 115 and Schedule 7.
