First year on H-1B with a spouse in India or abroad: how to file a joint 2026 return, step by step

The two routes to a joint 2026 Form 1040 in your first H-1B year, set by your start date, then each step in order: Form 4868 if you need it, your spouse's ITIN, the statements, signing from two countries and mailing.

$32,200 standard deduction on a joint 2026 Form 1040, once you both choose to treat your spouse abroad as a US resident

By F1TaxReturn Tax Team. Published . Facts checked against the sources below on . 10 minute read.

In short

  1. If you are a US resident on December 31, 2026 and your spouse lived abroad all year as a nonresident alien, you can both choose to treat your spouse as a US resident and file one joint 2026 Form 1040.
  2. If your earlier US days were all exempt F-1 days, an H-1B start on or before July 2, 2026, followed by staying in the US, makes you a resident, and the joint return is due Thursday, April 15, 2027.
  3. After a later start, such as October 1, 2026, you need the first-year choice: file Form 4868 and pay the tax figured as a nonresident by Thursday, April 15, 2027, then mail the joint return after you meet the 2027 test and by Friday, October 15, 2027.
  4. Your spouse applies for an ITIN on Form W-7, box e, generally signs it themselves, and the W-7 goes on the front of the paper return, mailed to the IRS ITIN Operation in Austin.
  5. In our example, $90,000 of 2026 pay costs $14,512 of federal income tax on Form 1040-NR and $6,440 on a joint Form 1040, which is $8,072 less.

You can file a joint 2026 Form 1040 in your first H-1B year with a spouse in India or elsewhere abroad. You must be a US resident on December 31, 2026. You and your spouse then both choose to treat your spouse as a US resident for the year (Publication 519).

You then file one ordinary joint return, not a dual-status one. On H-1B since 2025 or earlier? Follow the steps for H-1B workers since 2025.

Spouse moved to the US in 2026? Read F-1 to H-1B and married.

Note

These steps use the 2025 Publication 519 and Form 1040 instructions (the 2026 editions are not out) and the 2026 draft form.

Which route makes you a resident on December 31, 2026?

With 183 counted days in 2026, you are a resident under the substantial presence test (route 1). With fewer, you need the first-year choice and the 2027 test (route 2).

Timeline of the two routes to a joint 2026 return and their dates.A timeline from July 2026 to October 2027 for an H-1B worker whose spouse lived outside the US all of 2026. Route 1, 183 counted days in 2026: with no earlier counted days, your H-1B status starts (or you arrive) by July 2, 2026 and you stay in the US, and your residency generally starts on your first counted day; you mail the joint Form 1040 with Form W-7 by April 15, 2027. Route 2, the first-year choice, for example an H-1B start on October 1, 2026 after F-1: residency starts October 1, 2026; by April 15, 2027 you file Form 4868 and pay the tax figured as if you were a nonresident all year; on June 2, 2027 you meet the 2027 test if you were in the US every day from October 1, 2026 and from January 1, 2027; October 15, 2027 is the last day to mail the joint Form 1040 with Form W-7, so the green bar from June 2 to October 15, 2027 is the window to mail it.

On both routes you are a US resident on December 31, 2026 and your spouse is not.
  1. Find your H-1B status start date on your Form I-797, not the approval date (F-1 to H-1B guide).
  2. Count your 2026 days plus a third of 2025's and a sixth of 2024's, leaving out exempt F-1 days (IRS).
  3. Route 1 needs 183. With no earlier counted days, that means an H-1B start (after exempt F-1 days) or an arrival by July 2, 2026, then staying here. Residency generally starts on your first counted day (IRS).
  4. Route 2, for fewer days (92 after an October 1 start), uses the first-year choice. It needs no US residency in 2025, 31 days in a row, and presence on at least 75% of the days from the first of them to December 31. Up to 5 days abroad count toward the 75%, and exempt F-1 days count for neither condition. From October 1: all of October and at least 69 of the 92 days; residency starts October 1.
  5. Route 2 also needs the 2027 test: 183 minus 30.67 (a third of 92) = 152.33, so 153 days. If you are here every day from January 1, you meet it on Wednesday, June 2, 2027.

Will a joint return lower your tax?

If your spouse has no income, a joint return usually costs much less. Form 1040-NR generally allows no standard deduction; a joint return has $32,200 and brackets twice as wide (Revenue Procedure 2025-32).

Worked example: Noor, H-1B from October 1, 2026, spouse in India

Noor, an illustrative F-1 student since August 2022, earned $60,000 on OPT in Texas from January 1 to September 30, 2026, then $30,000 on H-1B. Noor was here all year, claims no treaty benefit, and has a spouse in India with no income.

A: Form 1040-NR, married filing separately B: joint Form 1040 (both choices)
Standard deduction $0 $32,200
Taxable income $90,000 $57,800
Federal income tax $14,512 $6,440

A: $5,800 + 22% of ($90,000 minus $50,400) = $5,800 + $8,712 = $14,512. B: $90,000 minus $32,200 = $57,800, then $2,480 + 12% of ($57,800 minus $24,800) = $2,480 + $3,960 = $6,440. The joint return costs $14,512 minus $6,440 = $8,072 less; the IRS Tax Table can differ by a few dollars. Same figures as F-1 to H-1B and married, whose spouse lives in the US.

  1. Work out your own figures; a student treaty benefit, such as India's Article 21(2), could change column A.
  2. If your spouse earns abroad, that pay goes on the joint return too (Publication 54); read the decision guide first.
  3. Weigh the cost: while the choice lasts, neither of you can generally claim treaty benefits as a resident of another country. Once it ends, neither of you can ever make it again (IRS).

What do you collect before you start?

A joint return covers both spouses' worldwide income for all of 2026, including your months before the H-1B (Publication 519).

  1. Your 2026 W-2s (due by Monday, February 1, 2027) and any 1099s.
  2. Either spouse's 2026 income abroad and the tax paid on it there.
  3. The highest 2026 balance and the December 31 balance of each account or other financial asset either of you holds abroad, for the FBAR and Form 8938.
  4. Your spouse's passport, birth details, address abroad and any foreign tax number.

Convert each amount to dollars at the rate on the day it was received or paid (IRS). The IRS generally "accepts any posted exchange rate that is used consistently" (IRS).

On route 2, what do you file by April 15, 2027?

File Form 4868 by Thursday, April 15, 2027, because you cannot file the joint return until you meet the 2027 test. Pay with it the tax "figured as if you were a nonresident alien the entire year" (Publication 519).

  1. Figure that tax on a married-filing-separately Form 1040-NR, as Publication 519 allows: $14,512 for Noor.
  2. List both names in joint-return order, your SSN on line 2 and "ITIN TO BE REQUESTED" on line 3 (2025 Form 4868).
  3. Enter the tax on line 4, your withholding on line 5 and your payment on line 7 (2025 form).
  4. Mail it, without Form W-7, to the address in its "Where To File a Paper Form 4868" table (Form W-7 instructions). The 2025 table has rows by state and for Form 2555, dual-status and Form 1040-NR filers; ask a preparer which fits you, and check the 2026 form.
  5. On the joint return, report the payment on Schedule 3, line 10 (2025 form).

If you will not meet the 2027 test, file Form 1040-NR by the extended date instead (Form 4868 guide).

How does your spouse apply for an ITIN on Form W-7?

A spouse who cannot get an SSN applies on Form W-7, box e, "Spouse of U.S. citizen/resident alien", sent with the joint return (Form W-7 instructions, Rev. December 2024).

  1. Check "Apply for a new ITIN" and box e; on its dotted line, enter your name and SSN.
  2. Line 1a: your spouse's name as on the passport and the return.
  3. Line 2: where the IRS mails documents back; line 3: the street address abroad.
  4. Lines 4 to 6b: birth information, citizenship, any foreign tax number.
  5. Line 6c: any US visa in your spouse's passport (type, number, expiry date), with the passport pages showing it, or "N/A" if none. Line 6g: "N/A". Leave no section blank.
  6. Line 6d: check "Passport" and enter its issuer, number and expiry date, and "Never entered the United States" as the entry date if true.
  7. Line 6e: "No/Don't know" unless your spouse ever had an ITIN or IRSN.
  8. Your spouse signs in original; you may sign only with Form 2848 attached and the power of attorney box checked.

Send the original passport (not expired) or a copy certified by its issuer or a US embassy or consulate (services vary; ask first); notarized copies are refused (ITIN FAQs). A Certifying Acceptance Agent in the US or abroad can check the passport, return it and mail the package, for a fee (IRS, ITIN guide).

Watch out

The W-7 instructions limit the passport "date of entry" rule to dependents, but the IRS page on ITINs from abroad says a passport without one "is no longer accepted". If your spouse has never entered the US, ask an acceptance agent first.

How do you fill in the joint Form 1040?

File one 2026 Form 1040 as "Married filing jointly", leaving your spouse's SSN space blank (Form W-7 instructions).

  1. Under "Other Information" on the 2026 draft Form 1040, check the box for treating a nonresident spouse "as a U.S. resident for the entire tax year" and enter their name. Ask a preparer about the draft's new work-authorization question.
  2. Report both spouses' worldwide income and take the $32,200 standard deduction. Leave line 12c (2025 form and 2026 draft), "You were a dual-status alien", unchecked (Publication 519).
  3. With any account abroad, attach Schedule B and answer Part III, line 7a (2025 form), even if no FBAR is due (2025 Schedule B instructions). Ask a preparer about accounts only your spouse holds.
  4. For your spouse's pay abroad, add Form 2555 (an electing spouse "can qualify" for its physical presence test) or Form 1116 (Form 2555 instructions).
  5. Add Form 8938 if your joint specified foreign assets passed $100,000 on December 31 or $150,000 at any time ($400,000 and $600,000 if either of you qualifies as living abroad) (Treas. Reg. 1.6038D-2). Ask a preparer which apply.
  6. If you leave out exempt F-1 or OPT days in 2026, attach Form 8843, unsigned (it is signed only when filed alone), as Publication 519 requires.

What goes in the two statements?

The joint choice needs a statement signed by both spouses; route 2 adds a first-year choice statement. Attach both to the joint return; the IRS texts do not say where in it (Publication 519, 2025 Form 1040 instructions).

  1. Build statement 1 from the items in Publication 519. Build statement 2 from the IRS first-year choice page, which asks for your 2026 days; add your 2027 days, which Publication 519's list asks for.
  2. For a pending ITIN, ask your preparer what to write.

Worked example: Example wording, from the IRS items

Statement 1: "On December 31, 2026, [resident spouse's name] was a U.S. resident alien and [nonresident spouse's name] was a nonresident alien. We choose to be treated as U.S. residents for the entire 2026 tax year." Then each spouse's name, address and SSN or ITIN.

Statement 2, route 2 only: "[Name and address.] I make the first-year choice for 2026. I was not a U.S. resident in 2025. I am a U.S. resident under the substantial presence test in 2027. Days of presence: [number] in 2026; [number] in 2027. 31-day period: October 1 to 31, 2026. Continuous presence: October 1 to December 31, 2026. Days of absence treated as presence: none."

How do you sign, assemble and mail the return from two countries?

Both spouses sign by hand, or one signs under the other's power of attorney. With Form W-7 attached, the package goes on paper to the IRS ITIN Operation in Austin (Form W-7 instructions).

  1. Sign the return and the joint-choice statement, then send them with Form W-7 for your spouse to sign by hand (Publication 501). Typed or digital signatures are not valid on paper (2025 Form 1040 instructions).
  2. Or your spouse signs a Form 2848 that lets you sign, and you attach it to the return. This needs at least 60 days' continuous absence from the US before the due date. Its instructions for an agent require lines 1 to 3, the line 4 box and the line 5a "Sign a return" box. On line 5a, write their statement, giving "continuous absence from the United States" as the reason.
  3. Put Form W-7 on the front, attach the W-2s, order forms by Attachment Sequence number and include the passport or certified copy.
  4. Mail to Internal Revenue Service, ITIN Operation, P.O. Box 149342, Austin, TX 78714-9342. By private delivery: Internal Revenue Service, ITIN Operation, Mail Stop 6090-AUSC, 3651 S. Interregional, Hwy 35, Austin, TX 78741-0000.

Watch out

Do not use the Form 1040 mailing address.

With US certified mail, the clerk's postmark on your receipt counts as the mailing date (Treas. Reg. 301.7502-1).

What happens after you mail it?

The IRS processes Form W-7 first, then the return. Allow 7 weeks, or 9 to 11 weeks from January 15 to April 30 or if you applied from overseas (IRS).

  1. Notice CP565 gives your spouse the ITIN; check the name and date of birth on it (IRS).
  2. Mailed documents come back to the line 2 address within 60 days.
  3. If Noor paid $14,512 through withholding and Form 4868, $8,072 comes back once the joint return is processed.

What else is due, and what happens in 2027?

As a US resident, you may also have to file a 2026 FBAR if your accounts abroad together passed $10,000; ask a preparer whether your months before residency count. The choice also continues into 2027 until suspended or ended (IRS).

  1. File the FBAR online with FinCEN by April 15, 2027, or by October 15, 2027 with the automatic extension (IRS).
  2. Your residency, by the 2026 test or the first-year choice, makes you a US person for the FBAR. The joint choice does not make your spouse one (IRM 4.26.16, FBAR guide).
  3. A state that taxes wages (state income tax guide) can have its own rule for a spouse abroad; ask your preparer.

What to do next

  1. Find your route and arrange your spouse's passport or a Certifying Acceptance Agent.
  2. Ask a preparer who works with nonresident spouses to compare joint and separate returns. F1TaxReturn prepares Form 1040-NR, Form 8843 and four state returns only for students who were nonresidents all year, not Form 1040 (joint or separate), Form 4868 or Form W-7.
  3. Route 1: mail the joint return by Thursday, April 15, 2027.
  4. Route 2: Form 4868 and payment by April 15, 2027, then the joint return after the 2027 test, by Friday, October 15, 2027.

Questions students ask

Does my spouse have to come to the US to get an ITIN?

No. Your spouse can mail their original, unexpired passport with the return, or a copy certified by its issuer or a US embassy or consulate (services vary, so ask first). A Certifying Acceptance Agent abroad is another way. On Form W-7, line 6d, a spouse who has never been to the US writes "Never entered the United States" as the date of entry. The IRS page on ITINs from abroad says a passport without a US entry date "is no longer accepted". The W-7 instructions apply that rule to dependents, so ask an acceptance agent first.

My H-1B started October 1, 2026. Why must I wait to file the joint return?

The first-year choice that makes you a resident on December 31, 2026 depends on meeting the 2027 substantial presence test. The IRS says you cannot file the return or the choice statement until you meet it, which with 92 counted days in 2026 means 153 days in 2027. File Form 4868 and pay by Thursday, April 15, 2027 in the meantime.

Can I sign the joint return for my spouse?

For a spouse abroad, only with a power of attorney attached to the return. The Form 2848 instructions allow another person to sign for someone continuously absent from the US for at least 60 days before the due date. That Form 2848 must have the line 5a "Sign a return" box checked and the statement the instructions set out, naming that absence as the reason. Publication 501's advice for a spouse who is away is simpler: send the prepared return to your spouse to sign. Form W-7 also needs your spouse's own signature unless a Form 2848 is attached to it.

Do we have to file jointly again for 2027?

No. The choice to treat a nonresident spouse as a resident continues into 2027 and later years, but you may file joint or separate returns in those years. Either way, both of you report worldwide income until the choice is suspended or ended.
