Okay - so - roughly speaking, our family income (wife + I) is projected to be ~$140k in taxable income (we actually earn more - but this our US "taxable" amount after retirement 401k contributions and such). Anyhow, in the states I will pay roughly $16,000 in federal income tax on that amount based on the standard deduction and 1 child tax credit.
Based on Canada's income taxes, I would pay $26,000+ in FEDERAL income tax alone (with the $11k standard deduction equivalent"). On top of that, I would have to pay province income taxes on that $140k as well - which obviously depends on your province, but let me just estimate it at an additional 10% flat - which would be an additional $14,000 on top of that $26,000. We're already talking paying $40k total in income taxes, which is $24k more than what I pay now. This isn't even getting into GST/HST/PST - which is more than my sales tax rate (8.25%) and property tax rates.
So tell me again, how is this cheaper?
