In Maclean’s, Stephen Gordon explains why the only kind of tax hikes that seem in any way “popular” are particularly bad if implemented:
Magical thinking might be smart politics, but it’s not very good economics. Here are the two most popular themes:
- Higher corporate income taxes. From a political marketing point of view, the appeal of increasing corporate income tax (CIT) rates is obvious: “Hey, I’m not a corporation, so it’s no skin off my nose.” But the economics of CIT rates are very dodgy indeed: higher CIT rates are the most costly way of generating revenue and are most harmful to economic growth. It also turns out that workers and consumers are the ones who ultimately bear the burden of higher CIT rates. (If you start taxing corporate profits, shareholders will eventually move their money to jurisdictions with more competitive rates, reducing the availability of investment capital. In the long-run, that results in lower output and weaker labour demand. More on that here.) But even if you were willing to pay these costs, higher CIT rates don’t generate much in the way of new revenues.
- Increased taxes on high earners. While there may be good reasons for wanting to use the personal income tax system to counter recent trends in the concentration of income, policymakers should be under no illusions about how much new revenue taxing the rich will bring in. There simply aren’t that many high earners to tax, and they have access to expert tax planning advice: there is overwhelming evidence showing that those with high incomes can and will respond to higher tax rates by reporting lower taxable income.
