The information I provided is for any taxpayer that moves out of the US . US citizens and green card holders have to file a full year resident US return no matter where they live. TurboTax is only for full year resident returns. US residents filing a full year resident return must include their worldwide income. If you filed in TurboTax and did not include your worldwide income, you will need to amend your return. Please see Publication 519 page 9 on last year of residency. You can either use December 31, 2018 as your ending date or you have to file a dual status return (part year resident and part year nonresident). Please see page 33 for the restrictions for dual status taxpayers. <a rel="nofollow" target="_blank" href="
