Most members of the Armed Forces are U.S. citizens or resident aliens. However, if you have questions about your alien status or the alien status of your dependents or spouse, you should read the information in the following paragraphs and get Publication 519.
Under peacetime enlistment rules, you generally cannot enlist in the Armed Forces unless you are a citizen or have been legally admitted to the United States for permanent residence. If you are an alien enlistee in the Armed Forces, you are probably a resident alien. If, under an income tax treaty, you are considered a resident of a foreign country, see your base legal officer. Other aliens who are in the United States only because of military assignments and who have a home outside the United States are nonresident aliens. Guam and Puerto Rico have special rules.
Residents of those areas should contact their taxing authority with their questions.
Resident Aliens
You are considered a U.S. resident alien for tax purposes if you meet either the green card test or the substantial presence test for the calendar year (January 1 – December 31). These tests are explained in Publication 519. Generally, resident aliens are taxed on their worldwide income and file the same tax forms as U.S. citizens.
Treating nonresident alien spouse as resident alien. A nonresident alien spouse can be treated as a resident alien if all the following conditions are met.
- One spouse is a U.S. citizen or resident alien at the end of the tax year.
- That spouse is married to the nonresident alien at the end of the tax year.
- You both choose to treat the nonresident alien spouse as a resident alien.
- A declaration that one spouse was a nonresident alien and the other was a U.S. citizen or resident alien on the last day of the year,
- A declaration that both spouses choose to be treated as U.S. residents for the entire tax year, and
- The name, address, and taxpayer identification number (social security number or individual taxpayer identification number) of each spouse. If the nonresident alien spouse is not eligible to get a social security number, he or she should file Form W–7, Application for IRS Individual Taxpayer Identification Number (ITIN). ITINs may be available through the nearest overseas base legal office or U.S. consulate.
Ending the choice. Once you make this choice, it applies to all later years unless one of the following situations occurs.
- You or your spouse revokes the choice.
- You or your spouse dies.
- You and your spouse become legally separated under a decree of divorce or separate maintenance.
- The Internal Revenue Service ends the choice because of inadequate records.
If the choice is ended for any of these reasons, neither spouse can make the choice for any later year. This applies to a divorced individual who previously made the choice and later remarries.
Choice not made. If you and your nonresident alien spouse do not make this choice:
- You cannot file a joint return. You can file as married filing separately, or head of household if you qualify.
- You can claim an exemption for your nonresident alien spouse if he or she has no gross income for U.S. tax purposes and is not another taxpayer’s de-pendent (see Exemptions, later).
- The nonresident alien spouse generally does not have to file a federal income tax return if he or she had no income from sources in the United States. If a return has to be filed, see the next discussion.
- The nonresident alien spouse is not eligible for the earned income credit if he or she has to file a return.
