Quick Answer
Yes — you can file jointly with a spouse who has an ITIN. A noncitizen, nonresident spouse needs an SSN or ITIN to be listed on the return. To file married filing jointly, both spouses sign an IRC §6013(g) election treating the nonresident spouse as a U.S. resident, which means reporting worldwide income for the year. This is tax information, not advice.
Can I File Jointly With a Spouse Who Has an ITIN?
Yes. A spouse who is not a U.S. citizen or resident needs an SSN or ITIN to appear on a joint or separate return. If your spouse already has an ITIN, you can list that number and file married filing jointly, provided you make the election to treat the nonresident spouse as a U.S. resident for the tax year.
The ITIN is the spouse's identifier on the Form 1040 — it does not by itself decide whether you file jointly or separately. That choice depends on the §6013(g) election covered below. If you are new to the process, our guide to filing taxes with an ITIN walks through the basics of using the number on a return.
Does My Nonresident Spouse Need an SSN or an ITIN?
Your spouse needs whichever number they are eligible for. A spouse who can get a Social Security number must use the SSN. A spouse who is not SSN-eligible files Form W-7 to get an ITIN instead. Either number is required to list the spouse on a joint or separate return — there is no third option.
The catch with the ITIN: you cannot e-file the year you apply. The W-7 must travel on paper with the tax return, so that first filing is mailed. To understand the difference between the two numbers and which applies to your spouse, see ITIN vs. SSN.
How Do I Treat a Nonresident Spouse as a U.S. Resident for Taxes?
You make the IRC §6013(g) election. Attach a signed statement to your joint return declaring the choice to treat your nonresident spouse as a U.S. resident for the entire tax year. Both spouses must sign it. Once made, the election applies for that year and all later years until it is ended or suspended.
The election is what unlocks married filing jointly with a nonresident spouse. The signed statement should include both names, addresses, and identifying numbers (the SSN or ITIN), plus a declaration that you are choosing to be treated as U.S. residents for the year. The IRS explains the requirements on its Nonresident Spouse page; more detail is in IRS Publication 519.
- Confirm your spouse is not SSN-eligible and complete Form W-7 to request an ITIN.
- Prepare your Form 1040 as married filing jointly.
- Write the §6013(g) election statement, signed by both spouses, declaring the choice to treat the nonresident spouse as a U.S. resident for the year.
- Attach the W-7 (with required identity documents) and the signed election statement to the paper return.
- Mail the package to the IRS — you cannot e-file the year you apply for the ITIN.
What Income Do We Report if We File Jointly?
Worldwide income for both spouses. Once you make the §6013(g) election, the joint return must include all income earned anywhere in the world by either spouse, including the nonresident spouse's foreign wages, interest, and other earnings. This obligation continues for every later year the election stays in effect.
Reporting foreign income does not always mean paying U.S. tax twice. The Foreign Tax Credit can offset tax already paid to another country, and the Foreign Earned Income Exclusion may exclude a portion of foreign wages. These mechanics can be involved, so many couples with foreign income work with a preparer experienced in cross-border returns.
Is Married Filing Jointly or Separately Better With an ITIN Spouse?
It depends on your numbers, but the tradeoff is clear. Married filing jointly gives a larger standard deduction and joint brackets but requires reporting both spouses' worldwide income. Married filing separately avoids reporting the spouse's foreign income, needs no election, but uses higher rates and loses some credits. The spouse still needs an ITIN either way.
| Factor | Married Filing Jointly | Married Filing Separately |
|---|---|---|
| §6013(g) election required | Yes | No |
| Standard deduction | Larger (joint) | Smaller |
| Report spouse's foreign income | Yes | No |
| Tax rates | Joint brackets | Higher rates |
| Spouse needs an ITIN | Yes | Yes |
The larger standard deduction often makes MFJ attractive when the nonresident spouse has little or no foreign income. When the spouse earns substantial income abroad, the worldwide-income obligation can outweigh the deduction. Compare the year-specific figures in our standard deduction with an ITIN guide before deciding.
How Do I Apply for My Spouse's ITIN When Filing Jointly?
File Form W-7 with the joint paper return. The W-7, the required identity documents, the §6013(g) election statement, and your Form 1040 are mailed together to the IRS. You cannot e-file the year you apply. After the IRS assigns the ITIN, it is printed on the processed return and used on future filings.
Plan for paper processing time, which can run several weeks. Once the number is issued, future joint returns can usually be e-filed. For a full walkthrough of the W-7, accepted documents, and where to mail it, see how to apply for an ITIN. The Taxes & Insurance hub collects related filing guides.
Can the §6013(g) Election Be Revoked?
Yes, but think carefully first. The §6013(g) election can be ended or suspended, and it also stops automatically in certain situations such as the death of a spouse. The important catch: once the election is revoked, it generally cannot be made again with the same spouse, so a one-time switch is effectively permanent.
Because revocation usually closes the door on filing jointly with that spouse later, couples typically revisit the decision only when foreign income or circumstances change significantly. This page covers the general rules; for your specific situation, a tax professional can confirm how revocation would apply to your returns.
Frequently Asked Questions
Do I have to report my spouse's foreign income?
If you make the §6013(g) election to file married filing jointly, yes — both spouses must report worldwide income, including your nonresident spouse's foreign earnings, for that year and later years until the election ends. The Foreign Tax Credit or Foreign Earned Income Exclusion may offset tax already paid abroad.
Can I claim the standard deduction if my spouse is a nonresident?
Yes, if you file married filing jointly using the §6013(g) election. Treating your nonresident spouse as a U.S. resident for the year lets you claim the larger joint standard deduction and use joint tax brackets. Married filing separately does not give the same standard deduction and uses higher rates.
What if my spouse never lived in the U.S.?
You can still file jointly. The §6013(g) election lets you treat a spouse who has never lived in the U.S. as a resident for tax purposes for the whole year. Your spouse still needs an ITIN, so attach Form W-7 and the signed election statement to a paper return — you cannot e-file the year you apply.
Can I switch from married filing separately to jointly in a later year?
Yes. You can make the §6013(g) election in a later year to start filing jointly, treating your nonresident spouse as a U.S. resident from that point. Be careful: once the election is revoked, it generally cannot be made again, so weigh the worldwide-income tradeoff before changing.
Does filing jointly affect my spouse's immigration status?
Filing taxes is an IRS matter that is separate from immigration status, and a tax return does not by itself change a spouse's immigration status. For any question about how filing might relate to a visa, green card, or other status, consult a qualified immigration attorney rather than relying on tax guidance.
Can we e-file once the spouse has an ITIN?
Generally yes. You cannot e-file the year you apply for the ITIN because Form W-7 and the signed election statement must be mailed with a paper return. Once the IRS assigns the ITIN, future joint returns can usually be e-filed using that number, just like a return with an SSN.
