An efficient tax system is not just about lower rates. To be competitive we must also look at how we tax, how that affects our businesses, and what has been holding them back in the past. The Bill legislates for reform of the taxation of foreign branches, as well as making interim changes to the outdated controlled foreign companies rules—a process started and consulted on under the previous Government. This will stem the tide of businesses leaving our shores for more favourable climes, and will ensure that the UK is an attractive place to locate and headquarter. This shows that Britain is once again open for business.
