I've posted on this general subject before.
Assume I am am American citizen married to a Canadian citizen who lives and works in Canada but chooses to be treated as a US Resident. My understanding is that we can file married joint, and we would get a credit against our US taxes for the amount she pays to Canada, subject to certain limits.
Here are my questions:
1) Can we take the same deductions in computing taxable income for her expenses as for mine. For example, can her provincial income tax be deducted, as my state income taxes can? Same for deductions to her retirement plan (the Retirement Savings Plan in Canada is similar to US IRA's)?2) I know the tax credit is limited, in some form it is something like:
Joint taxes * Her Income/Total Income
In this formula, is "her income" and "total income" the total income from all sources or taxable income? Would my income be after payments into my 401(k)?
3) Assuming we own a home together in Canada, can we take deductions for mortgage interest and property taxes on our joint return? I assume we can, since this would either be her "primary" home or at least my "secondary" home.Thanks in advance.
