As a Canadian citizen, you are required to pay tax on your income from all sources worldwide, regardless of its origin. Therefore, you must report all domestic and foreign income on your tax return. However, under the Canada/US tax treaty, you will receive a foreign tax credit, which means that you won't be taxed twice.

Thank you for choosing TurboTax.

Thanks for the reply. Is there a tax credit form in turbotax ? How can I add it ?
