The US is the only developed country in the world that taxes foreign-sourced income of non-residents. This means that US citizens (including so-called 'Accidental Americans') who meet certain minimum income thresholds still have to file a US federal income tax return to declare their worldwide income if they live or earn abroad.
What is it?
The Foreign Tax Credit gives Americans who pay income tax abroad a tax credit worth one dollar for every dollar of tax that they have paid to a foreign government.
The credit can be claimed against income taxes paid on all types of foreign-sourced income (e.g. wages, dividends, rents, royalties, and interest). It can only be claimed against income taxes though, and not for other types of taxes such as sales taxes, VAT, luxury taxes, or property related taxes.
“If you choose to take the foreign tax credit, and the taxes paid or accrued exceed the credit limit for the tax year, you may be able to carry over or carry back the excess to another tax year.” - the IRS
When should I use the Foreign Tax Credit?
The Foreign Tax Credit is a good option for Americans who are paying income tax to a foreign government at a higher rate than the US rate. So for example, if a US expat was living in a European country that was taxing their (foreign-earned) income of $100,000 at a rate of 35%, they could claim $35,000 of US tax credits. The US federal income tax due on the same income would however just be $21,037 (in 2016), so that in this case the expat would have $13,963 (35,000 – 21,037) of excess tax credits that they could carry forward and use in future years. In this way, if an expat lived and worked in a foreign country that has higher income tax rates than the US for 5 years before returning home again for example, they could build up a good amount of tax credits and so make a significant saving on their future tax liability after returning to live in the US.
If on the other hand you live in a country with lower income tax rates than in the US, and particularly if your foreign-earned income is less than $100,000, it may be more advantageous to claim the Foreign Earned Income Exclusion rather than the Foreign Tax Credit.
How do I claim the Foreign Tax Credit?
The Foreign Tax Credit is normally claimed using form 1116, which should be attached to your federal return. A separate form 1116 Is required for every foreign-sourced income stream.
In some cases, such as if your only foreign earned income is 'passive' (e.g. from interest and dividends), you can claim the Foreign Tax Credit using form 1040. However if you do you can't carry excess credits forward for future use.
Yes. If your income is more than the Foreign Earned Income Exclusion limit (around $100,000), and your income is sourced in a country with lower income tax rates than the US, it may be in your best interest to use the two in conjunction. Bear in mind though that you can only claim the Foreign Tax Credit on income over the Foreign Earned Income Exclusion threshold.
If you are living abroad but haven't been filing US taxes, don't worry, but we strongly recommend that you consider catching up using the Streamlined Procedure amnesty program before the IRS comes to you.
