The actions you need to take depend on whether or not your wife is eligible for a social security number (SSN). If she is eligible and you and your spouse tend to file a joint return, claiming her personal exemption and she has not received a card by the time your return is due, you may obtain an extension of time to file by using Form 4868 (PDF), Application for Automatic Extension of Time to File U.S. Individual Income Tax Return. If you wish to file a joint return with your spouse, claiming her personal exemption and she is not eligible to obtain a social security number at the time you are required to file, your spouse must obtain an Individual Taxpayer Identification Number (ITIN) from the IRS, by completing Form W-7 (PDF), Application for IRS Individual Taxpayer Identification Number. If she is unable to obtain an ITIN by the time your return is due, you may obtain an extension of time to file by using Form 4868, Application for Automatic Extension of Time to File U.S. Individual Income Tax Return. Refer to Tax Topic 304 , Extensions of Time to File Your Tax Return, for more information.

. Otherwise, you will have to file as married filing separately without claiming her personal exemption. If you do file as married filing separately, you may later amend your return to the filing status married filing jointly and claim her personal exemption when your wife obtains a (SSN or ITIN). This is done using Form 1040X (PDF), Amended U.S. Individual Income Tax Return. Generally, Form 1040X must be filed within three years after the date you filed the original return or two years after the date you paid the tax, whichever is later. Refer to Tax Topic 308, Amended Returns for more information.

By provision of the income tax treaty between the U.S. and Canada, benefits paid under the Canada Pension Plan (CPP), Quebec Pension Plan (QPP), and Old Age Security (OAS) program to a U.S. resident are taxable, if at all, only in the United States. These Canadian benefits are treated as U.S. social security benefits for U.S. tax purposes. Thus, under section 86 of the Internal Revenue Code, the portion of the benefits that is taxable will depend on your total income. If your total income is above certain limits, a maximum of 85% of your benefits will be subject to U.S. tax.

Canadian benefits that are treated as U.S. social security benefits are reported on line 20a and 20b of Form 1040 or line 14a and 14b of Form 1040A.

Under the 1997 protocol to the Canada - U.S. tax treaty, the Canadian and US governments agreed to return to a residence-based system under which social security benefits are taxable exclusively in the country where the recipient resides. As a result, the entry for line 14b would be $0.00.

United States citizens living abroad are required to file annual U.S. income tax returns and report their worldwide income if they meet the minimum income filing requirements for their filing status and age. You must contact the Canadian Government to determine whether you must file a Canadian tax return and pay Canadian taxes. For the United States income tax return, you will have several options available to you regarding claiming a foreign tax credit or excluding some or all of your foreign earned income.

You must comply with both U.S. and Canadian filing requirements. In the United States, you generally are required to file a return if you have income from the performance of personal services within the United States. However, under certain circumstances, that income may be exempt from payment of U.S. tax pursuant to the U.S.-Canada income tax treaty. You need to determine what type of visa you have, and how that impacts your residency status in the United States. If, based on the tax code and your visa status you are treated as a U.S. resident, then your entitlement to treaty benefits will be impacted.

In the United States, you generally are required to file a return if you have income from the performance of personal services within the US. The type of return to file would depend upon whether you are a resident of the U.S. for purposes of U.S. tax law. There are several tests to determine residency, including the substantial presence test, which is based on how many days you are present in the U.S. over a period of three years. Refer to Tax Topic 851 for information about which return to file. If you are simultaneously a U.S. resident under U.S. law and a Canadian resident under Canadian law, you should consult the U.S.-Canada income tax treaty for rules that would treat you as a resident of only one country. It is also possible that you may have to file a dual-status return in the U.S. if you qualify as a U.S. resident for only part of the year. Refer to Tax Topic 852 for dual-status information.

Benefits paid under the Canada Pension Plan (CPP), Quebec Pension Plan (QPP), and Old Age Security (OAS) program to a U.S. resident are taxable, if at all, only in the United States. According to the U.S. - Canada income tax treaty, taxation of these benefits is based on residence. U.S. citizens or green card holders who reside in Canada are not subject to U.S. tax on this income.

These Canadian benefits are treated as U.S. social security benefits for U.S. tax purposes. Thus, under section 86 of the Internal Revenue Code, the portion of the benefits that is taxable will depend on your income and filing status. If your modified adjusted gross income is above certain limits, a maximum of 85% of your benefits will be subject to U.S. tax. Refer to Tax Topic 423 for information about determining the taxable amount of your benefits. Any benefit under the social security legislation of Canada that would not be subject to Canadian tax if paid to a resident of Canada is not subject to U.S. tax.

Canadian benefits that are treated as U.S. social security benefits are reported on line 20a and 20b of Form 1040, U. S. Individual Income Tax Return or line 14a and 14b of Form 1040A.

Although Canadian registered retirement savings plans are similar to individual retirement accounts (IRAs), they do not meet the requirements for qualification as IRAs under section 408(a) of the Internal Revenue Code. As a result, the earnings of such a plan are includable currently in the gross income of the beneficiary of the plan for United States income tax purposes. Whether or not the earnings are distributed. However, a beneficiary of certain Canadian retirement plans may elect for a tax year (the current year) to defer United States income tax on certain current-year earnings of the plan that are not distributed to the beneficiary. An election to defer is made by the beneficiary attaching to the beneficiary's United States federal income tax return, a statement that contains for each plan the information specified in Revenue Procedure 2002-23 , 2002-15 I.R.B. 744, or in any future Revenue Procedure that supersedes Rev. Proc. 2002-23. Additional filing requirements are detailed in Notice 2003-25, 2003-18 I.R.B. 855 and Notice 2003-57, 2003-34 I.R.B. 397.

Foreign currency needs to be translated into U.S. dollars to determine the amount of income (such as income from the sale of goods or services, dividends or interest) to report on a taxpayer's U.S. return and to determine gain or loss when foreign currency is disposed of. The proper translation rate depends on the item of income and whether the taxpayer is a cash or accrual method taxpayer.

. Dividends . Dividends are translated at the spot rate on the date received.

. Interest . Interest income that is not required to be accrued (because, for example, the taxpayer is an individual holding a debt instrument that does not have original issue discount) is translated at the spot rate on the date received. Interest income that is required to be accrued is translated at the average rate for each accrual period. When such interest is received the taxpayer will realize foreign currency gain or loss based on the difference in exchange rates used to accrue the interest and the spot rate on the date such interest is received. (A taxpayer may also realize foreign currency gain or loss on the principal when the instrument is sold or matures.)

. Payable and receivables . An accrual basis taxpayer may also realize foreign currency gain or loss with respect to a foreign currency denominated payable or receivable. Generally, foreign currency gain or loss is computed by reference to the change in exchange rates between the time the payable or receivable arises and when it is paid or received. For example, if an accrual basis taxpayer sells a product for L100 when L1= $1 with payment to occur in 90 days and receives payment of L100 when L1 = $1.20, the taxpayer will realize $20 ($120 - $100) of foreign currency gain. It should be noted that in certain circumstances, taxpayers may use spot rate conventions if consistent with the taxpayer method of financial accounting.

You can generally get the exchange rates from banks and U.S. Embassies. Other possible sources of exchange rate would be publications, such as the Wall Street Journal. If there is more than one exchange rate, use the one that most properly reflects your income.

Generally, you must file a tax return after the end of the tax year to claim a refund of withholding. Gambling winnings by nonresidents of the U.S. are generally taxed at a flat 30% tax rate. However, under the U.S./Canada Tax Treaty, residents of Canada may claim gambling losses, but only to the extent of gambling winnings. You should report both your total gambling winnings and your total gambling losses on page 4 of Form 1040NR (PDF), U.S. Nonresident Alien Income Tax Return, on the dotted portion of line 83. If you have net gambling winnings (after offsetting your total losses against your total winnings), you should include this net amount on line 83, column (d) of the Form 1040NR. You should also attach a copy of the Form 1042-S, Foreign Person's U.S. Source Income Subject to Withholding, showing the taxes withheld to your Form 1040NR.

A diary of your losses should be kept for your records.

To file a Form 1040NR you must have a valid identification number. Refer to Tax Topic 857 if you have not already been issued one.
