Taxes for US Expats – Filing Form 1040 From Abroad
If you’re an American citizen or green card holder, you’re required to file US taxes wherever in the world you live, reporting your worldwide income.
The US is almost the only country in the world that requires all of its citizens to file even if they live abroad. This means that US expats often have to file taxes twice, once to the IRS, and also in the country where they live (depending on the tax rules there).
This means that expats typically have to file extra forms along with form 1040 compared with Americans living stateside.
Differences for expats filing form 1040
Expats are required to file form 1040 just the same as Americans living stateside, reporting their worldwide income, including all their worldwide income sources and their deductions if necessary just as if they were living in the US. There are some differences however for expats filling form 1040 from abroad.
“If you are a U.S. citizen or resident alien, the rules for filing income, estate, and gift tax returns and paying estimated tax are generally the same whether you are in the United States or abroad.” – the IRS
The IRS doesn’t have an official currency exchange rate, and so accepts any officially posted rate, so long as the same rate is used consistently.
This gives expats some room for manoeuvre when filing, in terms of using a rate that is advantageous to them, so long as they are consistent in the rate that they use.
Expats claiming exemptions such as the Foreign Earned Income Exclusion also have to include them on form 1040, in field 21.
Expats with a foreign spouse should also seek advice before checking ‘married filing jointly’, as this can be either advantageous or disadvantageous depending on each expat’s particular circumstances.
Foreign account reporting
Many expats are behind with their US tax filing as they weren’t aware that they had to file form 1040 from abroad.
Expats who are three or more years behind can catch up without facing any penalties though using an IRS amnesty program called the Streamlined Procedure.
The Streamlined Procedure requires that expats file their last three federal tax returns (including back claiming the most beneficial exemptions), their last 6 FBARs (if necessary), and self-certify that their previous non-compliance was non-willful (i.e. unintentional).
