In general, expat tax returns are due June 15th of the year following the close of the prior calendar year. Two months later because you live outside of America.
Also, an automatic extension is available by requesting it for an additional six months from the normal April deadline date.
Please note! If you owe any tax, you need to pay this tax before April 15th to avoid interest. There is no two-month grace period for paying the tax, only for filing if you live and/or work outside of America.
