US citizen abroad with a nonresident alien spouse

The choice in plain terms

A married couple where one spouse is a U.S. citizen or resident alien and the other is a nonresident alien faces an awkward default. Without any action, the nonresident spouse is outside the U.S. tax system and the couple does not file jointly. The publication offers an alternative. If, at the end of your tax year, you are married and one spouse is a citizen or resident alien and the other a nonresident alien, you can choose to treat the nonresident spouse as a U.S. resident. The election also covers the case of a spouse who was a nonresident at the start of the year and a resident alien at the end, with the other a nonresident alien at year end.

Two rules follow. You and your spouse are treated as U.S. residents, for income tax and wage withholding purposes, for the year of the choice and all future years until it is terminated for one of the reasons in the publication's Table 1-1 or suspended because neither of you is a citizen or resident. And you must file a joint return for the year you make the choice, with a statement attached. It also means neither spouse can claim under a tax treaty not to be a U.S. resident for any year the choice is in effect.

What it means in practice

The publication's first example is Pat Smith, a U.S. citizen, and Norman, a nonresident alien. They attach a statement to their joint return, report worldwide income for the year and all later years unless the choice ends or is suspended, and must file jointly the first year but may file jointly or separately in later years. A second example covers two nonresident aliens, Bob and Sharon, where Bob becomes a resident alien in June and both choose resident treatment on a joint return for that year.

Worldwide income is the heart of the decision. A nonresident spouse who would otherwise owe nothing to the United States on foreign earnings now reports them. The publication notes that it may be advantageous to choose and file jointly, but once made, the choice requires worldwide reporting for each year unless it is suspended or terminated. A couple abroad should weigh that against the filing-status benefits and against any foreign tax credit or exclusion available to the citizen spouse.

The alternative: head of household

If you do not make the choice, the publication says you may be able to use head of household status. To do so you must pay more than half the cost of maintaining a household for certain dependents or relatives other than your nonresident spouse. Your nonresident alien spouse cannot be the person who qualifies you; the publication's question-and-answer section says that if you do not choose resident treatment you are treated as unmarried for head of household purposes, and you must have another qualifying person and meet the other tests.

How to make the choice

Attach a statement signed by both spouses to the joint return for the first tax year the choice applies. It must declare that one spouse was a nonresident alien and the other a citizen or resident alien on the last day of the tax year and that you choose to be treated as U.S. residents for the entire tax year, and it must give each spouse's name, address and SSN or ITIN. If one spouse died, include the name and address of the person making the choice for the deceased spouse.

Your spouse needs a Social Security number or an individual taxpayer identification number. If your spouse cannot get an SSN, they can apply for an ITIN on Form W-7 filed with the joint return on which you make the choice, and an ITIN used on an earlier return may need renewal.

You generally make the choice when you file, but you can also do it on a joint amended return on Form 1040-X, and if you do, you must also amend any returns filed after that year. The amended return must be filed within 3 years of the date you filed your original return or 2 years of the date you paid the tax, whichever is later. The calculator above applies that rule to the dates you enter.

How the choice ends

Once made, the choice applies to all later years unless suspended or ended in one of the ways in Table 1-1, and if it ends for one of those reasons neither spouse can make the choice in a later year. Either spouse can revoke it for any tax year, by the due date for filing that year's return, with a signed statement giving each spouse's name, address and SSN or TIN, the name and address of anyone revoking for a deceased spouse, and a list of any community property states, foreign countries and territories where either spouse is domiciled or has income-producing real property. Death ends it starting with the first tax year after the year of death, though a qualifying surviving spouse keeps it until the end of the last year joint rates may be used. Divorce or legal separation ends it as of the beginning of the tax year in which the separation occurs. The IRS can end it for any year in which either spouse failed to keep adequate records or to give access to them.

Suspension is different from ending. The choice does not apply to a later year in which neither of you is a citizen or resident at any time, and it comes back if one of you becomes a resident again. The calculator's drop-down summarizes each case.

If the citizen spouse lives and works abroad, the question of whether the income is excludable is separate. See the pages on the bona fide residence test and the 330-day physical presence calculator.
