The IRS provides a automatic 2-month filing extension for qualified US expat filers. However, this extension does not apply to tax obligations – interest starts accruingÂ on any tax due after the regular April deadline (ie, 18 Apr 2016 for Tax Year 2015). Please see below for other dates/deadlines for the 2015 tax year:
April 18 – Original tax day for non-expat filers (for Federal Income Tax Returns)
June 15* – Filing deadline for U.S. citizens or resident aliens residing overseas
*Does not apply to any tax due – interest starts accruing on any tax due after the regular April deadline (ie, 18 Apr 2016 for Tax Year 2015).
October 15 – Expat tax filers not able to file on time (within the 2-month auto-extension period) can request an additional extension to October 15 by filing Form 4868.
December 15 – Expat filers who are not able to file by the extended due date of October 15, can request an additional 2-month extension (to Dec 15) by sending a letter of request to the IRS along with explanation for the request. The letter must be sent by the extended due date of Oct 15 (see above), and the sender will not normally receive a reply unless the request is denied.
