Failing to claim the credit results in double taxation on your foreign income. You may lose the ability to carry forward unused credits if you miss the filing deadline.
Overview
Form 1116 is the primary mechanism for US taxpayers to claim a credit for income taxes paid or accrued to foreign countries or US possessions. This form is essential for preventing double taxation on the same income by allowing you to offset your US tax liability by the amount of tax you paid to a foreign government. The foreign tax credit is available to US citizens, resident aliens, and nonresident aliens who meet certain conditions. For US expats living in Canada, this form is particularly important because Canada has relatively high income tax rates, and the credit can significantly reduce or eliminate US tax on Canadian-source income. The credit is calculated on a per-category basis, with separate categories for passive income, general income, and other specific types. The credit is limited to the lesser of the actual foreign tax paid or the amount of US tax attributable to foreign-source income. Excess credits can be carried back one year or forward up to ten years. When used together with Form 2555, the foreign tax credit can only be applied to income that was not excluded under the foreign earned income exclusion.
