Moving Abroad as an American: What Changes on Your Taxes and What Does Not

Your move abroad can leave you with a new home, new accounts and the same US filing obligations. As a US citizen, your worldwide income generally remains subject to US income tax wherever you live. ¹

This is general information. Your CPA and counsel confirm the details for your case.

Start by separating the questions you need answered. Must you file? Which income belongs on the return? Which exclusion or credit applies? Which accounts or structures need separate reporting? Work through those questions before you treat your new country's tax position as your complete tax position.

What stays with you after departure

Under IRS filing rules, living abroad generally leaves you subject to the same income, estate and gift return requirements, and estimated-tax obligations, as people living in the United States. That doesn't mean everyone files every form. It means departure alone doesn't remove the obligation to check. ²

A particularly easy mistake is comparing only your taxable income after exclusions with a filing threshold. The IRS says gross income used to decide whether you must file includes income excluded as foreign earned income or a foreign housing amount. A calculation showing little or no tax due therefore isn't enough to establish that you have no return to submit. ²

For your filing threshold, confirm the current figure for your filing status and tax year. Put your complete income records beside that threshold, including income you intend to exclude. Someone else's filing status or last year's number isn't a reliable basis for your return.

What may change in your income-tax calculation

The maximum foreign earned income exclusion is $132,900 for tax year 2026, compared with $130,000 for 2025. These are year-specific maximums, not an automatic allowance created by buying a plane ticket. Review the eligibility tests and the credit alternative before selecting a treatment for your income. ³

The IRS requires amounts on a US return to be expressed in USD. If you're receiving income or paying expenses in another currency, keep the original records and document the USD translation used for the return. A bank statement in the local currency is useful evidence, but your return still needs dollar amounts. ²

Keep the year attached to every figure in your planning notes. Publication 54 became a continuous-use publication starting with tax year 2025; annual inflation-adjusted amounts were removed and must be taken from the annual Revenue Procedure. That is a practical reason to question an old saved checklist even when its general explanation still sounds right. ¹

Your filing extension and payment calendar are different

Publication 54 explains an automatic filing extension to June 15 for calendar-year filers whose tax home and abode are both outside the US and Puerto Rico on the regular due date. Interest on tax due still runs from April 15. The extra filing time is therefore something to plan around, not a reason to postpone estimating what you owe. ¹

A further extension to October 15 can generally be requested by June 15. For people qualifying for the automatic two-month extension, late-payment penalties are assessed from June 15. Establish the dates that apply to you and record filing, payment and extension actions separately. ¹

Your new bank account creates another reporting question

The IRS says an FBAR is required when you have a financial interest in, or signature authority over, foreign financial accounts whose aggregate value exceeded $10,000 at any point in the calendar year. It is filed electronically through FinCEN, separately from your tax return. Review the combined position instead of judging each new account on its own. ²

Form 8938 has a different framework. The IRS comparison gives abroad thresholds for unmarried or separately filing individuals of more than $200,000 at year-end or $300,000 at any time. For joint filers abroad, the figures are more than $400,000 and $600,000 respectively. Identify the category that applies to your filing status. ⁴

What this means for you

Your move creates a second set of records without automatically removing the first. Establish the US return, account-reporting and payment tasks before you choose another account or entity. You can then evaluate the new arrangement with its ongoing obligations visible.

What to do this month

• Gather your US and foreign income records for the same tax year, retaining the original currencies and dates. Flag any missing documents before preparation starts.
• Build one foreign-account inventory, including ownership and signature authority. Record which filing will cover each account and who will submit it.
• Separate the filing calendar from payment dates. Add the extension request as its own action instead of assuming the later date applies to everything.
• Write down the banking or residency change you are considering and the compliance question it raises. Resolve that question before signing the next application.

Common mistakes to avoid

• Treating a new address as proof that US filing stops.
• Assuming excluded income disappears from the filing-threshold calculation.
• Using a filing extension as a payment holiday.
• Looking at foreign accounts separately instead of checking the aggregate reporting rule.

The FNC angle

Your banking and residency decisions should be reviewed alongside your US compliance position. An FNC discussion can start with the account access, ownership or relocation problem you want to solve, while your CPA evaluates the tax treatment. Bring the unresolved questions to the same planning conversation before committing to a structure. You need a setup that makes sense for your circumstances, with the reporting work understood from the start.
