I am a U.S. citizen. If I move to Canada to live and work there as a Canadian permanent resident, do I pay both U.S. and Canadian Taxes?

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.

I am a Canadian citizen living and working in the U.S. for a U.S. employer on a visa. Do I need to file both a U.S. tax return and a Canadian tax return?

You must comply with both U.S. and Canadian filing requirements, if any. 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. You must contact the Canadian government to determine whether you must file a Candian tax return and pay Canadian taxes.

Are the Canada Pension Plan and Canadian Old Age Security Benefits taxable? If they are, please tell me where they should be entered on Form 1040.

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.

Is there an Internet site with the exchange rates to convert foreign currencies to American dollars?

What is foreign earned income? Is it income from a foreign source or income paid by a U.S. company while living abroad?

Earned income is pay for personal services performed, such as wages, salaries, or professional fees. Foreign earned income is income you receive for services you perform in a foreign country during a period when your tax home is in a foreign country and during which you meet either the bona fide residence test or the physical presence test. It does not matter whether earned income is paid by a U.S. employer or a foreign employer. Foreign earned income does not include the following amounts.

Do I have to meet the 330-day presence test or have a valid working resident visa to meet the requirement for foreign income exclusion?

To claim the foreign earned income exclusion, the foreign housing exclusion, or the foreign housing deduction, you must have foreign earned income, your tax home must be in a foreign country, and you must be one of the following:

U.S. tax law does not specifically require a foreign resident visa or work visa for this purpose, but you (must/should) comply with the other country's laws.

I am a nonresident alien. Can I take the foreign earned income exclusion if I meet the bona fide resident test or physical presence test? If yes, what is the tax form used for nonresident taxpayer?

No, nonresident aliens do not qualify for the foreign earned income exclusion. Only if you are a U.S. citizen or a resident alien of the United States and live abroad, may you qualify to exclude up to $80,000 of your foreign earned income for 2004. But, if you are the nonresident alien spouse of a U.S. citizen or resident alien, you can elect to be treated as a U.S. resident in order to file a joint return. In this case, you can take the foreign earned income exclusion if otherwise qualified. Refer to Publication 519, U.S. Tax Guide for Aliens, for detailed instructions on how to make this election.

However, nonresident aliens would be able to exclude their foreign earned income under the dual-status rules. Refer to Tax Topic 852 for dual-status information. A nonresident alien is generally not subject to U.S. tax on compensation for services performed outside the U.S.

I live in a foreign country. How do I get a social security number for my dependent who qualifies for a social security card?

Under my visa as a temporary nonresident alien, I'm not subject to social security and Medicare withholding. My employer withheld the taxes from my pay. What should I do to get a refund of my social security and Medicare?

If social security tax and Medicare were withheld in error from pay received which was not subject to the taxes, you must first contact the employer who withheld the taxes for reimbursement. If you are unable to get a refund from the employer, file a claim for refund with the Internal Revenue Service on Form 843 (PDF), Claim for Refund and Request for Abatement.

Are nonresident alien students, with F-1 or J-1 visas and employed by a U.S. company during the summer, required to have federal income taxes withheld from their paychecks?

The following discussion generally applies only to nonresident aliens. Wages and other compensation paid to a nonresident alien for services performed as an employee are usually subject to graduated withholding at the same rates as resident aliens and U.S. citizens. Therefore, your compensation, unless it is specifically excluded from the term "wages" by law, or is exempt from tax by treaty, is subject to graduated withholding. Nonresident aliens must follow modified instructions when completing Form W-4. Please refer to Publication 519, U.S. Tax Guide for Aliens, for directions on completing Form W-4 (PDF), Employee's Withholding Allowance Certificate.

I worked out of the country for one year. Do I have to pay U.S. income tax?

As a U.S. citizen, your worldwide income generally is subject to U.S. income tax, regardless of where you are living. However, you may qualify for the foreign earned income exclusion, foreign housing exclusion or foreign housing deduction, or the foreign tax credit. These tax benefits can reduce or eliminate the U.S. tax you would otherwise have to pay on your foreign income.

I am a U.S. citizen working for a U.S. firm in a foreign country. Is any part of my wages or expenses tax deductible?

U.S. citizens are taxed on their worldwide income, no matter where they work. Some taxpayers may qualify for the foreign earned income exclusion, foreign housing exclusion, or foreign housing deduction, if their tax home is in a foreign country and they were either a bona fide resident of a foreign country or countries for an uninterrupted period that includes an entire tax year, or were physically present in a foreign country or countries for at least 330 full days during any period of 12 consecutive months. If the taxpayer is temporarily away from his or her tax home in the United States on business (less than a year), the taxpayer may qualify to deduct away from home expenses (for travel, meals, and lodging ) but would not qualify for the foreign earned income exclusion.

I am a U.S. citizen living and working overseas. Can I have a tax credit on my U.S. taxes for the taxes I pay to the foreign country?

The foreign tax credit is intended to relieve U.S. taxpayers of the double tax burden when their foreign source income is taxed by both the United States and the foreign country from which the income is derived.

Generally, only income taxes paid or accrued to a foreign country or a U.S. possession qualify for the foreign tax credit. You can choose to take the amount of any qualified foreign taxes paid or accrued during the year as a foreign tax credit or as an itemized deduction.

To choose the foreign tax credit you must generally complete Form 1116 (PDF), Foreign Tax Credit and attach it to your Form 1040. You may claim credit without attaching Form 1116 if all of your foreign source income is passive income (such as interest and dividends) reported to you on a payee statement and the total amount of qualifying foreign taxes you paid or accrued is not more than $300 ($600 in the case of a joint return) and is also reported to you on a payee statement. To choose the deduction, you must itemize deductions on Schedule A, Form 1040.

You may not take either a credit or a deduction for taxes paid or accrued on income you exclude under the foreign earned income exclusion or the foreign housing exclusion. There is no double taxation in this situation because the income is not subject to U.S. tax.

How do I know if the U.S. has an income tax treaty with another country?
