The First-Year Choice for New H-1B Arrivals: How a Late-Year Start Can Make You a US Tax Resident Early

Started H-1B work this fall? An IRS election can make you a tax resident from the start of your H-1B stay, and for married couples it can unlock a full-year joint return.

Part of our guide to US taxes on F-1, OPT and H-1B.

If your H-1B job started late in 2026, the first-year choice election lets you be taxed as a US resident from the first day of a 31-day run of countable US presence, instead of as a nonresident for the whole year. It comes from Internal Revenue Code section 7701(b)(4), it is in effect and unchanged as of November 1, 2026, and it has one catch: you can make it only after you pass the substantial presence test for 2027, so most people file a Form 4868 extension by April 15, 2027 and elect later. For a single filer it often changes little. For a married couple it can open a full-year joint return.

Status as of 2026-11-01. In effect: the election and the 2026 standard deduction ($16,100 single, $32,200 married filing jointly, per the IRS 2026 inflation adjustments). Not yet published: the 2026 Publication 519 and 2026 Form 1040-NR instructions, so the 2026-27 dates below are our arithmetic from the 2025 edition. Draft only: a work-authorization question on the 2026 Form 1040.

What is the first-year choice election?

The first-year choice is an election under IRC 7701(b)(4) for someone who fails the substantial presence test in their arrival year but will pass it the next year. You are treated as a US resident from the first day of a qualifying 31-day stretch, and as a nonresident before it, so that year becomes a dual-status year.

Without it, a late-year starter is a nonresident for all of 2026 and files Form 1040-NR. The rules are in IRS Publication 519 (chapter 1), on the IRS page Tax residency status: first-year choice, in the statute, 26 U.S.C. 7701(b)(4), and in 26 CFR 301.7701(b)-4.

Common misconception, then correction. Many online summaries say the first-year choice makes you a resident "for the entire year." It does not. The IRS says you choose residency for part of the year "and be taxed as a dual-status individual for the current year," and Pub 519 says of dual-status returns: "You cannot use the standard deduction allowed on Form 1040 or 1040-SR." Only a married couple can make the whole year resident, through a separate spouse election.

Our guide to the dual-status tax return in your first US year shows how the two halves of that return are built.

Who qualifies for the first-year choice for 2026?

You qualify if you were not a US resident in 2025, are not one for 2026 under the green card or substantial presence test, will meet the substantial presence test for 2027, and pass two presence tests in 2026. Pub 519 states them for 2025; moved forward a year:

• 31 days in a row in 2026, physically present every day.
• 75% presence from the first day of that run through December 31, 2026. Up to 5 absence days count as presence for this test only, not for the 31-day run (26 CFR 301.7701(b)-4(c)(3)(iv)).
• The 2027 substantial presence test: 183 weighted days (every 2027 day, one-third of countable 2026 days, one-sixth of countable 2025 days), at least 31 of them in 2027, per the IRS substantial presence test page.
• No first-year choice made for 2025.

Your residency starting date is the first day of the earliest 31-day run that satisfies the 75% test. And, as Pub 519 puts it, "You do not have to be married to make this choice."

Do my F-1 or OPT days count toward the 31 days?

No. Days as an exempt individual, including an F-1 student on OPT or STEM OPT who complies with the visa, are excluded from all three counts. For a cap-gap student whose change of status to H-1B took effect on October 1, 2026, the count starts October 1.

Three cautions. File Form 8843: without it on time, the IRS says, "you cannot exclude the days" (see our Form 8843 guide). Check the 5-year limit: after more than 5 calendar years as an exempt student your days may already count, which can make you a 2026 resident with no election needed (see how the substantial presence test works). Read your approval date: if your petition was pending on October 1, you stayed in F-1 under cap-gap until the change took effect, as your I-797A and I-94 show.

I arrived on H-1B in December. Can I still elect?

Only if you were in the US by December 1, 2026 and present every day through December 31, because December 1 to 31 is exactly 31 days and the run allows no absence. Arrive December 2 or later and the 2026 election is closed: you are a nonresident for 2026, and a 2027 pass generally makes you a resident from your first day present in 2027 (Pub 519). A December paycheck with withholding still means a 2026 Form 1040-NR, due April 15, 2027 (June 15, 2027 without withheld wages; our arithmetic).

Which 2026 return fits your start date?

As of 2026-11; assumes no countable days before 2026 and a 2027 pass (our reading of Pub 519, 2025 edition). Anyone counting from July 2, 2026 or earlier reaches 183 days in 2026 and needs no election (our arithmetic).

Do you need an extension to make the first-year choice?

Almost always, because you cannot elect until you pass the 2027 test. The regulation says the alien "may not make this election until such time as he has satisfied the substantial presence test for the year following the election year."

Take the October 1 starter: 92 countable days in 2026 add about 30.7 weighted days, so 153 days in 2027 are needed, reached around June 2, 2027 with no trips. In our arithmetic, no one who qualifies for the 2026 election can pass the 2027 test by April 15, 2027, so the extension is the normal route.

Pub 519's route: file Form 4868 by April 15, 2027, which extends filing to October 15, 2027, and pay with it the tax you expect to owe "figured as if you were a nonresident alien the entire year," using Form 1040-NR to figure it. That payment is more than a way to limit interest. The regulation makes it a condition of the extension, and an election that skips the procedure leaves you a nonresident for 2026 unless you can show "clear and convincing evidence" of reasonable actions and "significant affirmative steps" to comply. Paying at least 90 percent of the nonresident-basis tax you actually owe counts as such a step (26 CFR 301.7701(b)-4(c)(3)(vi)).

If the 2027 test never arrives (you leave or fall short), there is no election: you file the 2026 Form 1040-NR, which Form 4868 also extends (Pub 519, chapter 7). Days in the US after an H-1B job ends still count, including the worker grace period of up to 60 days that applies today. DHS has proposed eliminating it (RIN 1615-AD22, Federal Register notice); comments close 2026-11-10, and it stays a proposal until a final rule is published.

Worked example: one October 1 start, filed three ways

Meera was on STEM OPT until September 30, 2026; her H-1B change of status took effect October 1 and she stays put. Her husband Arjun entered on H-4 on October 5 with no US income, after earning a salary abroad from January to September. Neither was a resident in 2025; both will pass the 2027 test.

As of 2026-11, from Pub 519 (2025 edition), chapters 1 and 6; dates are our arithmetic.

A versus B. For Meera alone, the election mostly relabels the year: her OPT wages are taxed under nonresident rules either way, the standard deduction stays barred, and B adds her foreign income from October 1. B can help with credits, since Pub 519 says "As a dual-status alien, you can generally claim tax credits using the same rules that apply to resident aliens," and it is the doorway to C. (A proposed rule, REG-119882-25, would bar the refunded part of the child tax credit and several other credits to non-"qualified aliens," including H-1B, H-4 and F-1 holders; comments closed 2026-10-05, and no final rule exists as of 2026-11-01.)

C. Because Meera is a resident on December 31, the couple can choose full-year residency and file jointly: Pub 519's "Nonresident Spouse Treated as a Resident" (IRC 6013(g)) if Arjun is still a nonresident at year end, or "Choosing Resident Alien Status" (IRC 6013(h)) if he makes his own first-year choice (his 88 countable days qualify the same way). The dual-status limits fall away: if all $32,200 of the deduction would otherwise be taxed at 22%, it saves $7,084 before counting the tax on Arjun's foreign salary (our arithmetic). The price: Arjun's foreign salary goes on a US return (a Form 1116 foreign tax credit may offset some), and under 6013(g) neither spouse can claim under a treaty not to be a US resident.

The 6013(g) choice carries into later years until ended or suspended; the 6013(h) choice covers one year and cannot be made again. For Social Security and Medicare withholding, the IRS says a spouse treated as a resident "may still be treated as a nonresident" (IRS nonresident spouse page). Joint-return and ITIN mechanics are in our guide to filing jointly with an H-4 spouse.

Meera's calendar: 31-day run complete 2026-10-31; her 75% test needs 69 of 92 days (any trip abroad after the change of status is a visa question for her employer's immigration attorney); Form 4868 and payment 2027-04-15; 2027 test passed around 2027-06-02; joint return by 2027-10-15.

If you are from India

An Indian student eligible under Article 21(2) of the US-India treaty may claim the standard deduction on Form 1040-NR ($16,100 for 2026, single), per IRS Publication 901; the treaty has no $5,000 wage exemption (that is China's Article 20). Whether Article 21(2) reaches your switch year depends on your facts. A dual-status return bars the standard deduction, so for a single filer the election alone can cost that benefit (our reading of Pub 519, chapter 6).

Is the first-year choice better than a dual-status return or a 1040-NR?

The first-year choice is a dual-status return, so compare three outcomes: a full-year 1040-NR, a dual-status return, or a joint full-year resident return. Single filers with only US wages often see little change; for married filers in a late-start year it is usually the only path to a joint return.

Questions for a tax professional who prepares nonresident and dual-status returns:

• Will you be married on December 31, 2026, and did either of you have foreign income before your start date?
• Do your foreign accounts exceed $10,000 in aggregate, which can mean an FBAR once you are a resident?
• Might you leave the US before passing the 2027 test, or were you an Indian student eligible for the Article 21(2) deduction?
• Does your spouse need an ITIN? It takes about 7 weeks, 9 to 11 in peak season (IRS ITIN page).

How to make the first-year choice, step by step

1. Pull your travel history from the CBP I-94 website and your I-797A, and note your first countable day in 2026.
2. Count your 2026 days against the 31-day run and the 75% test, listing any absence days you treat as presence.
3. Figure your 2026 tax on Form 1040-NR as if you were a nonresident all year.
4. File Form 4868 with the IRS by April 15, 2027 and pay that amount.
5. Log your 2027 days until you reach 183 weighted days.
6. Prepare your 2026 Form 1040: a dual-status return with a 1040-NR statement (labeled as in the worked example), or a joint return with the Filing Status checkbox ticked and your spouse's name entered.
7. Attach the first-year choice statement, with what the regulation calls "a signed declaration" of the election: name and address; that you make the choice for 2026; that you were not a resident in 2025; that you are a resident under the substantial presence test for 2027; your days present in 2027 (the IRS web page says 2026 instead, so ask your preparer about giving both); the dates of your 31-day run and continuous presence in 2026; any absence days treated as presence.
8. Attach Form 8843 for your 2026 F-1 days, the spouse statement signed by both of you if filing jointly, and Form W-7 if your spouse needs an ITIN.
9. Mail a dual-status return to the dual-status address on the back of the Form 1040 instructions by October 15, 2027. Pub 519 says dual-status taxpayers "cannot e-file" for tax year 2025; for a joint return carrying the statement, ask your preparer how it must be filed for 2026.

A qualifying parent can also elect for a qualifying dependent child who need not file (26 CFR 301.7701(b)-4(c)(3)(v)(B)). Keep copies: "Once you make the first-year choice, you may not revoke it without the approval of the IRS."

What changes once you are a resident

• Worldwide income. Foreign income you receive from your residency starting date is taxable in the US.
• Treaties. Benefits generally cover only the nonresident part of the year, with saving-clause exceptions; Pub 519 shows China's Article 20 student benefit surviving.
• FICA. H-1B wages carry Social Security and Medicare regardless of the election; nonresident F-1 OPT wages before your start date fall under the student exemption. See how H-1B status affects your taxes.
• Foreign accounts. The FBAR applies to US persons, including resident aliens, above $10,000 in aggregate; it is due April 15 with an automatic extension to October 15. See FBAR and FATCA for visa holders.
• The draft 2026 Form 1040. The draft (posted 2026-09-17) asks whether the filer and a joint-filing spouse are each a US citizen, US national or "an alien lawfully authorized to work in the U.S." It has no instructions yet; an H-4 spouse without an EAD should raise it with the preparer.

Common mistakes

• Treating the election as full-year residency. Only the spouse choice makes the whole year resident.
• Counting F-1 days, or skipping Form 8843. Exempt student days do not count, but without a timely Form 8843 they can; for a cap-gap switcher, the clock starts when the change of status takes effect.
• Filing in February 2027. Pub 519 says you cannot file the return or the statement until you pass the 2027 test; it describes the Form 4868 extension as the route.
• Skipping the extension payment. The regulation ties the extension to paying nonresident-basis tax by April 15, 2027, and a missed step can leave you a nonresident for 2026.
• Applying the 5-day allowance to the 31-day run. It helps only with the 75% test.
• Leaving the ITIN to the last week. The W-7 travels with the return and takes weeks.

Frequently asked questions

What is the first-year choice for tax residency?

It is an election under IRC 7701(b)(4) for someone who fails the substantial presence test in their arrival year but passes it the next year. You are treated as a US resident from the first day of a qualifying 31-day period and as a nonresident before it, so the year becomes a dual-status year, not a full-year resident year. It remains in effect as of November 2026.

Who qualifies for the first-year choice?

For 2026, you must not have been a US resident in 2025 or made this choice for 2025, must not be a resident for 2026 under either test, and must meet the substantial presence test for 2027. In 2026 you need 31 consecutive days of countable presence and presence on 75% of the days from the start of that run through December 31, with up to 5 absence days allowed for the 75% test only. Exempt F-1 student days do not count, and a December arrival must be in the US by December 1, 2026.

Do I need to file an extension to make the election?

Almost always. You cannot make the election until you meet the 2027 substantial presence test, which a late-2026 starter who stays in the US usually reaches in May or June 2027, after the April 15, 2027 due date. Pub 519 describes filing Form 4868 by that date, extending filing to October 15, 2027 (our arithmetic), and paying the tax figured as if you were a nonresident all year.

Can I file jointly with my spouse using the first-year choice?

Not with the election alone, because dual-status filers cannot file jointly. Once it makes you a resident on December 31, 2026, you and your spouse can choose to be treated as residents for all of 2026 under IRC 6013(g) if your spouse is still a nonresident on December 31, or 6013(h) if your spouse is also a resident then (for example, through their own first-year choice), and file a joint Form 1040 with the $32,200 standard deduction. Both of you are then taxed on worldwide income for the year, and a spouse without an SSN needs an ITIN.

Is the first-year choice better than a dual-status return?

The first-year choice produces a dual-status return, so the real comparison is a full-year Form 1040-NR, a dual-status return, or a joint full-year resident return. For a single filer with only US wages it often changes little, because dual-status filers cannot take the standard deduction. For a married couple it is usually what makes the joint return possible, at the cost of reporting both spouses' worldwide income.
