Hon DAVID PARKER: No, well, it's not related to that at all; in fact, this was one of the projects that I made clear to the Prime Minister, when I sought the revenue portfolio, that I wanted to do some work around, because I do think that there is a big gap in the understanding that we have in this Parliament and in our society as to what the effective tax rate is paid by different sectors of society. We know that very well for wage and salary earners, for people that earn their income through interest in the bank. We know the distribution of that across society. We know that low- and middle-income people spend about, roughly, two-thirds of their income on GST-inclusive goods and services, and the bottom eight to nine deciles—the mix of the third that is not on GST-inclusive goods and services changes within those deciles for lower-income people. They're spending about a third of their income on rent, which doesn't attract GST. For middle-income people, it's on their mortgage, and higher-income people it's phasing out of mortgages and going into savings. But, generally, in those bottom 80 percent or 90 percent, roughly two-thirds of people's income is spent on GST-inclusive goods and services, which means that the effective GST rate for all those people is roughly about 9 percent of their income, in addition to their income tax. Why I'm sure Chlöe Swarbrick is interested in those issues is that you have to have an understanding of the distribution of GST payments across society in order to have a real understanding as to what is the distribution of overall taxes by decile. So that's one of the reasons we're giving that information.
