Filing U.S. Taxes
U.S. income tax returns for a tax year are generally due on April 15. Taxpayers resident overseas are given an automatic two-month extension to file; however any tax due though must be paid by April 15 to avoid being charged penalties and interest. Applicants may request a further extension by completing and submitting Form 4868 to the IRS before the return due date.
