Scotland Bill

The hon. Gentleman makes a very fair point. Let me reassure him, first, that we have given a lot of attention to the technical issues of implementation, both in a high-level implementation group and, now, technical groups led by Her Majesty's Revenue and Customs, which are looking at all the different issues. The good news is that the software systems that were created for employees paying the Scottish variable rate under the original legislation were future-proofed and can identify Scottish taxpayers on the payrolls, wherever the company's head office is, ensuring that the identification of taxpayers is made as painless a process as possible and that the right amounts of tax are taken.
