Misunderstandings about capital gains taxes
Late last year we released a study showing how a province, specifically Alberta, could eliminate the provincial portion of the capital gains tax to lower the overall capital gains tax rate an entrepreneur, business owner or investor faces. The paper outlined the many benefits of a lower capital gains tax.
Two common criticisms of that study are worth responding to and clarifying. Both criticisms are rooted in the belief that a change in the capital gains tax overwhelmingly benefits high-income Canadians.
If one simply examines the incidence of capital gains taxes by income group (see table above), it’s easy to believe that reducing the capital gains tax would disproportionately benefit high-income Canadians. There are two problems with the data presented in in the table that lead to this conclusion — it shows that 58.4 per cent of capital gains taxes (net) were paid by those earning more than $250,000 in 2017. Thus the concern that a reduction in capital gains taxes would disproportionately benefit the top earners in Canada seems reasonable at first glance.
One of the better, more thorough examinations of capital gains taxes was completed by Prof. Herbert Grubel. His 2000 book, Unlocking Canadian Capital: The Case for Capital Gains Tax Reform, tackled this issue (along with many others) by examining the incidence of capital gains taxes by income group when the underlying capital gain is included in income versus when it’s excluded. Remember that half of a person’s capital gains are included in their taxable income.
The data presented in the table above updates and confirms Prof. Grubel’s original 2000 analysis. His insight in 2000 was that including one-time capital gains income in a person’s total income were skewing the results of which income groups and thus which Canadians were actually incurring capital gains taxes by boosting their taxable income. Consider a business owner who after many years of owning and running a business and sells it. Alternatively, consider a person who gains inheritance. These examples of one-time income are included in the underlying income determining that 58.4 per cent of capital gains taxes paid by those earning more than $250,000 per year or perhaps even more striking that 81.3 per cent of capital gains taxes in 2017 were paid by those earning more than $100,000.
The results are distinctly different when capital gains are removed from income. The chart below shows the distribution of capital gains taxes by four different income groups when capital gains are included and excluded from income. Such a change in the definition of income means that the share of capital gains taxes paid by those earning more than $250,000 falls from 58.4 per cent to 31.9 per cent.
