Revenue from personal income tax is not that much. More like about 20%. Corporate is about a third of that.
More like a quarter …
Here are some stats (2009 latest)
Total revenues $585,799 (million)
Personal Income Tax: $189,222
Social insurance taxes: $35,404
Corporate Income Tax: $50,277
I'll bet the proportion for succeeding years is even more skewed towards citizens and away from business (or so economists have been warning us).
Income tax is over 30% but add on social insurance, health premiums and taxes that are business deductions and/or are passed directly onto consumers like GST, gasoline, import duties, liquor, and you are easily over 50% for personal taxes.
I do understand that businesses do contribute in other ways, but not when people start becoming a profit center and nothing else.
