For U.S. citizens or resident aliens, the rules for filing income tax returns and paying estimated tax are generally the same whether taxpayers are in the U.S. or abroad. All worldwide income is potentially subject to U.S. income tax. For U.S. citizens living oversea, there are additional filing requirements/deadlines that need to be addressed. Please see below for a summary of the most important tax deadlines.
