Ms Anne Gunnell:

Any tax, because of its very definition in legislation, is complicated. We must evaluate what the impact will be. The design of a tax is very important. Often we see something introduced that is well intended from a policy point of view but when conditions, exemptions and the various rules that underpin a piece of tax legislation are layered on, it can have an unintended impact on a particular cohort of taxpayer, a type of transaction, or whatever. That is why we say everything should be properly evaluated and why we encourage proper stakeholder consultation so those things can be considered in advance of introducing any kind of new tax.
