My situation:
-I am a Dual US/Canadian Citizen
-I work for a Canadian company, pay Canadian income taxes
-I live in the US (at least I am in the US 80% of the year, heading back to Canada once a quarter)
-I am married to a US Citizen who has no ties to Canada, and has US Income
-we file jointly in the US

My question: I have been told by my tax person that I will only get about 77% of my foreign tax credits from the IRS against my paid Canadian taxes. They are estimating I owe about $500/quarter in US taxes from my Canadian income. How is this not double-taxation? Is there any program under the Canada Revenue Agency that would allow me not to pay Canadian taxes on my income if I'm paying US taxes on it? Help!
