U.S. citizens and resident aliens — including those with dual citizenship — with a foreign bank or financial account face an April 15 deadline to file their annual Report of Foreign Bank and Financial Accounts (FBAR). They should also check to see if they have a U.S. tax liability and a federal tax return filing requirement.

Here is a rundown of key points to keep in mind:

Deadline for reporting foreign accounts

The deadline for filing the FBAR is the same as for a federal income tax return. This means that the 2018 FBAR, Form 114, must be filed electronically with the Financial Crimes Enforcement Network (FinCEN) by April 15. FinCEN grants filers missing the April 15 deadline an automatic extension until Oct. 15, to file the FBAR. Taxpayers don’t file the FBAR with individual, business, trust or estate tax returns. Taxpayers who want to paper-file their FBAR must call the Financial Crimes Enforcement Network’s Regulatory Helpline to request an exemption from e-filing.

In general, the filing requirement applies to anyone who had an interest in, or signature or other authority, over foreign financial accounts whose aggregate value exceeded $10,000 at any time during 2018. Because of this threshold, the IRS encourages taxpayers with foreign assets, even relatively small ones, to check if this filing requirement applies to them. The form is only available through the BSA E-Filing System website.

Taxpayers with foreign financial accounts that report their accounts to the U.S Treasury Department should also visit the FBAR Fact Sheet posted on IRS.gov.

IRS ends Offshore Voluntary Disclosure Program (OVDP)

The IRS will continue to use tools besides voluntary disclosure to combat offshore tax avoidance, including taxpayer education, whistleblower leads, civil examination and criminal prosecution. The IRS continues to use streamlined filing compliance procedures that will remain in place and be available to eligible taxpayers. But, as with OVDP, the IRS said it may end the streamlined filing compliance procedures at some point. Full details of the OVDP and streamlined procedures are available at Options Available for U.S. Taxpayers with Undisclosed Foreign Financial Assets.

Most people abroad need to file

An income tax filing requirement generally applies even if a taxpayer qualifies for tax benefits, such as the Foreign Earned Income exclusion or the Foreign Tax credit, which substantially reduce or eliminate U.S. tax liability. These tax benefits are only available if an eligible taxpayer files a U.S. income tax return.

A special extended filing and payment deadline applies to U.S. citizens and resident aliens who live and work abroad. For U.S. citizens and resident aliens whose tax home and abode are outside the United States and Puerto Rico, the income tax filing and payment deadline is June 17. Taxpayers have two extra days because the normal extended deadline — June 15 — falls on a Saturday this year.  The same applies for those serving in the military outside the U.S. and Puerto Rico on the regular due date of their tax return.

Interest, currently at the rate of 6% per year, compounded daily, will apply to any payment received after the regular April 15 deadline. See U.S. Citizens and Resident Aliens Abroad for details.

Nonresident aliens who received income from U.S. sources in 2018 also must determine whether they have a U.S. tax obligation. The filing deadline for nonresident aliens is April 15. See Taxation of Nonresident Aliens on IRS.gov.

Special income tax return reporting for foreign accounts and assets

In addition to the annual FBAR requirements outlined above, 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 these items for the country in which each account is located.

Also, separate from the foreign accounts reporting requirements above, certain taxpayers may also have to complete and attach to their return Form 8938, Statement of Specified 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.

Specified domestic entity reporting

Certain domestic corporations, partnerships and trusts that are considered formed for the purpose of holding (directly or indirectly) specified foreign financial assets must file Form 8938 if the total value of those assets exceeds $50,000 on the last day of the tax year or $75,000 at any time during the tax year.

For more information on specified domestic entity reporting, as well as the types of specified foreign financial assets that must be reported, see Do I need to file Form 8938, Statement of Specified Foreign Financial Assets? and its instructions.

Report in U.S. dollars

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

Both FinCen Form 114 and IRS 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. For more information on exchange rates, see Foreign Currency and Currency Exchange Rates.

Expatriate reporting

Taxpayers who relinquished their U.S. citizenship or ceased to be lawful permanent residents of the United States during 2018 must file a dual-status alien tax return, attaching Form 8854, Initial and Annual Expatriation Statement. A copy of the Form 8854 must also be filed with Internal Revenue Service, Philadelphia, PA 19255-0049, by the due date of the tax return (including extensions). See the instructions for this form and Notice 2009-85, Guidance for Expatriates Under Section 877A, for further details.
