Start with your U.S. filing responsibilities
U.S. citizens and resident aliens generally remain subject to U.S. tax on worldwide income while living abroad. Whether a return is required depends on the applicable filing rules. Having no U.S. tax due after an exclusion or credit does not automatically remove the filing obligation.
List wages, self-employment, investments, pensions, and other income wherever received. Tell your preparer about a move, a change in residency status, and foreign business or account interests.
Keep filing and payment dates separate
Qualifying taxpayers abroad may receive an automatic two-month extension to file and pay. Interest generally runs on unpaid tax from the regular payment deadline. Further filing extensions do not necessarily extend payment time.
Check the current-year dates and eligibility rather than assuming every overseas taxpayer has the same deadline. Keep a calendar for U.S. returns, foreign returns, estimated payments, and information reports.
Check relief and account reporting separately
A foreign earned income exclusion or foreign tax credit may reduce double taxation when requirements are met. These are different provisions with different limits and interactions; neither should be applied simply because you have a foreign address.
Foreign bank and asset reporting can apply separately from income tax. Ask your preparer to assess FBAR and Form 8938 obligations, including their different thresholds, definitions, and filing systems. Filing one does not automatically satisfy the other.
Prepare a useful overseas tax packet
Collect travel dates, addresses, employment contracts, foreign tax returns, tax payment evidence, account statements, and prior U.S. returns. Identify the currencies used and preserve the exchange-rate method applied.
If prior returns or account reports are missing, seek advice before making corrections. The right process depends on the facts. Contact Jacobwise early so the team can review your U.S. filing needs and coordinate any specialist assistance.
