Divorcing Abroad? Filing Status, Residency, and the Tax Year That Changes Everything

Divorce is a legal event with a tax date attached. Abroad, it also becomes a residency event—sometimes for two countries at once.

The calls I take usually arrive in the same shape: someone separated during the year, the decree is not final, the foreign spouse has an ITIN or does not, there are children, there is a house, and there are accounts in both countries. Every one of those facts changes an answer.

This guide is general information, not individualized tax or legal advice. Family law, treaty rules, and state residency are fact-specific and often need an attorney's involvement.

The date that decides your filing status

For U.S. federal purposes, your filing status is generally determined by your marital status on December 31 of the tax year.

• Divorce final on or before December 31: you are unmarried for that year. Single or head of household may be available.
• Divorce not final by December 31: you are still married for that year. Married filing jointly or married filing separately are the options—even if you lived apart the whole year.

There is a middle path: if you are still married but lived apart for the last six months of the year, paid more than half the cost of keeping up a home for a qualifying child, you may qualify as head of household under the "considered unmarried" rules. The requirements are strict. (IRS Publication 501)

The practical consequence: a decree that slips from December to January changes the entire return—rates, standard deduction, credits, and whether the foreign spouse's income is on your return.

The foreign spouse questions

If you were married to a nonresident alien during the year, three issues surface:

1. ITIN and reporting. A joint return generally requires the spouse to have an ITIN or SSN. If the spouse does not have one, the joint return may be filed with a W-7 or the return may need to be filed separately. (IRS: ITIN)
2. The 6013(g)/(h) election. A U.S. citizen or resident married to a nonresident alien can elect to treat the spouse as a U.S. resident for tax purposes, which allows a joint return. The election has ongoing consequences and termination rules—it is not a one-year switch. (FileAbroad: the 6013(g) election)
3. Revoking or terminating the election after divorce. If the election was in place, the divorce and the election's termination rules interact. This is a specialist conversation, not a checkbox.

If you filed jointly in prior years and are now separated, the prior returns are not automatically wrong—but the current year's facts decide the current year's treatment.

Dependents and credits

Children are usually the hardest part:

• The custodial parent generally claims the child, but the other parent can claim the child if the custodial parent signs a release (Form 8332).
• Head of household and the child tax credit follow different rules and can point to different parents.
• Foreign-born children may need an ITIN or a Social Security number, and the documents to prove the relationship.
• Support records matter—especially when one parent lives abroad and support moves across borders and currencies.

If a foreign court order allocates custody or support, remember that it does not bind the IRS. The U.S. tests still apply.

The residency split

This is where expat divorces differ from domestic ones. Two overlapping questions:

U.S. state residency. If one spouse moved abroad and the other stayed, the former state may continue to treat one or both as residents. Domicile, days, and the documentation of the move decide it. The guide on state tax residency and domicile covers the analysis.

Foreign residency. Where each spouse actually lives now changes treaty positions, the FEIE, and the foreign tax credit. A separation that moves one spouse to a new country mid-year changes that spouse's filing facts for the year.

The two analyses share evidence: the date of the move, the address trail, the driver's license, the lease, and where the children go to school.

Accounts, property, and the reporting that follows

Asset transfers in a divorce are generally tax-neutral between spouses (or former spouses) if they happen within the rules for incident-to-divorce transfers. What is not neutral is the reporting:

• FBAR and Form 8938: if you still have signature authority or an interest in a foreign account after separation, the reporting generally continues until the interest or authority ends. Removing yourself from an account is a bank process—do it and keep proof.
• Transfers of foreign property: the transfer may be tax-neutral but still has currency and basis consequences for the eventual sale.
• Withdrawals and retirements: dividing retirement accounts has specific rules; a foreign pension or retirement arrangement adds reporting questions.
• The house: if the marital home is sold, the Section 121 exclusion and ownership/use tests change when one spouse has moved out or abroad.

What to prepare before the conversation

• The decree, separation agreement, or filing dates—and the exact date the marriage ended (or has not).
• Prior three years of returns, including how you filed and any 6013 elections.
• Children's documents: SSN/ITIN, custody terms, support records.
• Account ownership and signature authority changes, with dates.
• Residency evidence for each spouse: visas, leases, days present, state filings.

Two sentences in this area cost more than they save: "We're basically divorced" and "We'll handle it next year." The first is not a filing status, and the second decides it.

The year of a divorce or separation usually forces three decisions at once: filing status, who claims the dependents, and where each spouse is a tax resident. Share the broad facts in the intake—the decree or separation date, where each of you lives now, and whether there are children or foreign accounts—and I'll tell you what this year's return can and cannot do.

Start your intake and say DIVORCE.
