> In the case of canada (and other countries with a tax treaty with the US), this is a non-issue because you either pay 0% withholding or can deduct the tax from your country's tax return (presumably the tax treaty also contains provisions for your country to net out the difference with the US). This is what Intuit says for that type of income: > If taxes were deducted from your income, you can claim those taxes as if you paid them to the CRA. Because you have a duty to report all your U.S. income on your Canadian return, the income is deemed taxable as Canadian income. The usually lower U.S. income tax rate could leave you with an amount owing for the difference between the United States and Canadian income tax rates. So, just for the sake of an example, say I make $100, US income taxes are 15%, and Canadian income taxes are 25%. The way I understand it, I pay $15 in US tax. That's calculated as if I paid it to the CRA, so now I only owe them $10 to make up the difference. The HUGE issue with that is that my country (Canada) only gets $10 for things like healthcare and social programs while the US gets $15 for doing exactly nothing. So it might not make a difference in terms of the money in my bank account, but it's detrimental to me in terms of a lack of funding for government services.
