US Expat Tax Guide: Plan, Qualify and File
Start with where you actually live and work, then determine filing obligations, compare available relief and organize the records. A mailing address, immigration visa and tax residence answer different questions.
Sources checked September 17, 2026. General guidance; apply the rules to your circumstances.
1. Identify the jurisdictions and income
US citizens and resident aliens generally remain subject to US worldwide-income filing rules while abroad. The country where you live or work may also tax you, and a former US state may retain a residence or source-income claim. List your citizenship or status, homes, work locations and each type of income before choosing an exclusion.
2. Review your former-state departure
Moving abroad does not automatically end state residence, but there is no universal requirement to acquire another US domicile first. Apply the former state’s law to the actual move. New York has domicile, statutory-residence and exception rules; California has a facts-based analysis and a conditional employment-abroad safe harbor. Nonresident source-income obligations can remain after a genuine departure.
3. Check FEIE eligibility before using its limit
For 2026 income, the maximum foreign earned income exclusion is $132,900 per qualifying person; the 2025 maximum is $130,000. A foreign tax home and a qualifying residence or presence test are required. The physical presence test generally needs 330 full days in foreign countries during a consecutive 12-month period, not merely days outside the United States. Investment income is not foreign earned income, and FEIE does not itself eliminate self-employment tax.
4. Compare the foreign tax credit
The foreign tax credit can reduce US tax on eligible foreign-source income taxed abroad, subject to creditability and limitation rules. Income categories, timing and carryovers matter. Taxes attributable to FEIE-excluded income cannot also generate a credit. Compare complete scenarios using the same income and tax year before making or revoking an election.
5. Separate tax returns from information reporting
A zero income-tax balance does not automatically eliminate filing. Foreign accounts, assets, companies, trusts and gifts can trigger separate reports. FBAR and Form 8938 have different conditions and are not substitutes for each other. Assemble account maximums, ownership details and prior filings before selecting forms. Confirm filing extensions separately from payment and interest rules.
6. Keep your home and correspondence records accurate
If Florida is genuinely your established domicile, records should support that position. A declaration can document an established home; a commercial mailbox can manage correspondence. Neither alone guarantees another state will accept nonresidence. Banks and licensing agencies may require residential information distinct from the mailing address. If your actual permanent home changes abroad, reassess statements and registrations accordingly.
7. Resolve the destination and transfer details
Foreign residence, incentive programs and work permission have their own conditions. A digital-nomad visa does not necessarily grant a tax exemption. For money transfers, the 2026 federal remittance tax depends on the transaction and funding method; it is not a tax on every overseas bank transfer. Review the relevant destination authority and the provider’s disclosure.
Put the plan into practice
Use the state wage comparison for its stated assumptions, or the Help Center for document and mail tasks. For Florida mail and documentation services, review what Your Tax Base provides. Tax filing and legal conclusions depend on the underlying facts.

Common questions
Must every expat establish Florida domicile?
No. The actual move and the former state’s law determine residence. A foreign domicile can be relevant; there is no universal requirement to choose another US state.
Does FEIE eliminate all US taxes?
No. It applies to qualifying foreign earned income within its limits. Other income, self-employment tax and state obligations can remain.
Can a virtual mailbox satisfy every bank and licensing rule?
No. A mailing service does not automatically satisfy residential-address or identity requirements.
What should I prepare before meeting a tax adviser?
A travel and work calendar, home records, worldwide income, foreign tax payments, account and entity information, and prior returns and elections.
