You guys realize Canada operates on a marginal taxation rate, correct? Like, you don't actually pay 33% taxes on your total income.
For each of the above brackets, you pay the associated tax rate on each *PORTION* of your income. Your effective tax rate is most likely much lower than 33% of your total income.
An example (from this site:
The person making $50,000 per year would not pay $15,250 in tax ($50,000 x 30.5%). Instead, his/her tax would be calculated like this:
$12,298 at 0% = $0
($19,369 minus $12,298) at 15.0% = $1,061.50
($48,535 minus $19,369) at 25.0% = $7,291.25
($50,000 minus $48,535) at 30.5% = $446.52
Total tax = $8,798.27
I sincerely doubt you would be further ahead in the US with a private health insurance plan, even if you lived in a state without state income tax.
