Yes. For example, Budget 2008 says there are going to be 700,000 more people taken off the tax rolls between the time the budget was tabled and 2009. That's because the threshold keeps going up. We already have 7 million people not paying taxes.
But there have been changes, such as the escalating of that threshold. Every time you escalate the threshold, as was done in previous budgets under a previous government, you actually take more people off the tax rolls, which means that when you do income tax changes, those people aren't affected because there's nothing to pay. You only get the benefit as a taxpayer.
