In the old days when the marginal income tax rate was up to over 90%, the tax rate on cap gains was “only” 25%. I think it’s now something like 40% - Obama got a big increase passed, without pretending that he would get more revenue from it, but just for “you didn’t build that" spite.
Marginal tax of 90%? WOW!
I believe that the highest in Canada, was in Quebec, at 60%. The highest in Alberta is now 39%, I believe. Don’t know, because the days of income like that for me never existed. Of course, we also have the GST, a consumption tax on most goods and it is a flat 5%. Other than Alberta, all other jurisdictions have an addition Provincial sales tax.
