The IRS reminded U.S. citizens and resident aliens, including those with dual citizenship who have lived or worked abroad during all or part of the year, that they may have a U.S. tax liability and a filing requirement.

Most People Abroad Need to File

A filing requirement generally applies even if a taxpayer qualifies for tax benefits, such as the foreign earned income exclusion or the foreign tax credit , that substantially reduce or eliminate their U.S. tax liability. These tax benefits are not automatic and are only available if an eligible taxpayer files a U.S. income tax return.

The filing deadline is  June 15 for U.S. citizens and resident aliens whose tax home and abode are outside the United States and Puerto Rico, and for those serving in the military outside the U.S. and Puerto Rico, on the regular due date of their tax return. To use this automatic two-month extension, taxpayers must attach a statement to their return explaining which of these two situations applies. See U.S. Citizens and Resident Aliens Abroad for details.

Nonresident aliens who received income from U.S. sources also must determine whether they have a U.S. tax obligation. The filing deadline for nonresident aliens can be April 15 or June 15 depending on sources of income. See Taxation of Nonresident Aliens on IRS.gov.

Special Reporting for Foreign Accounts and Assets

Federal law requires U.S. citizens and resident aliens to report any worldwide income, including income from foreign trusts and foreign bank and securities accounts. In most cases, affected taxpayers need to complete and attach Schedule B to their tax return. Part III of Schedule B asks about the existence of foreign accounts, such as bank and securities accounts, and usually requires U.S. citizens to report the country in which each account is located.

Taxpayers with an interest in, or signature or other authority over, foreign financial accounts whose aggregate value exceeded $10,000 at any time during the year must file with the Treasury Department a Financial Crimes Enforcement Network (FinCEN) Form 114, Report of Foreign Bank and Financial Accounts (FBAR). It is due to the Treasury Department by April 15, must be filed electronically and is only available online through the BSA E-Filing System website. For details regarding the FBAR requirements, see Report of Foreign Bank and Financial Accounts (FBAR).

In addition, certain taxpayers may also have to complete and attach to their return Form 8938, Statement of Foreign Financial Assets.  Generally, U.S. citizens, resident aliens and certain nonresident aliens must report specified foreign financial assets on this form if the aggregate value of those assets exceeds certain thresholds. See the instructions for this form for details.

IRS Simplifies Reporting for Canadian Retirement Accounts

The IRS has eliminated a special annual reporting requirement that has long applied to taxpayers who hold interests in either of two popular Canadian retirement plans. This is part of an IRS change announced in October making it easier for taxpayers with these plans to get favorable U.S. tax treatment. As a result, many Americans and Canadians with registered retirement savings plans (RRSPs) and registered retirement income funds (RRIFs) no longer need to file Form 8891 each year reporting details on these plans. This change does not affect any other reporting requirements that may apply, such as FinCEN Form 114 and Form 8938.

Report in U.S. Dollars

Any income received or deductible expenses paid in foreign currency must be reported on a U.S. return in U.S. dollars. Likewise, any tax payments must be made in U.S. dollars.

Both Form 114 and Form 8938 require the use of a Dec. 31 exchange rate for all transactions, regardless of the actual exchange rate on the date of the transaction.  Generally, the IRS accepts any posted exchange rate that is used consistently.
