Individual Expats who have been living overseas during a tax year get an automatic extension to file until June 15 of the following year.
This is in addition to the right to request an extension until October.
Although the June 15 extension does not require an advance request, the taxpayer should assert the right to it in his or her filing in accordance with IRS regulations.
Expats filing based on the June extension are liable for any interest accruing after April 15.
As always, the April and June dates are subject to slight adjustment if they fall on a weekend or holiday.
