Arrived mid-year on H-1B? Your tax residency depends on the substantial presence test, not your visa. Here's how dual-status filing, the MFJ election, and FBAR rules work in year one.
You landed in the US on an H-1B, started your job, and now tax season is coming. The first thing to understand: your visa does not decide how you're taxed — your days in the country do. The IRS sorts everyone into resident or nonresident for tax purposes using the substantial presence test, and most people who arrive mid-year on H-1B end up as neither for the full year. They're dual-status: nonresident for the months before arrival, resident after.
That one fact drives everything else in your first-year return — which form you file, whether you get the standard deduction, whether your Indian salary from January matters, and whether your Indian bank accounts suddenly become reportable. This post walks through each piece. For the full cross-border picture, start with The NRI's Complete Guide to US Taxes and come back here for the first-year specifics.
The substantial presence test counts your days: all days this year, one-third of last year's days, one-sixth of the year before, with a minimum of 31 days in the current year. Hit a weighted 183 and you're a resident for tax purposes. We break down the formula with worked examples in our guide to the substantial presence test, but here's what it means for typical H-1B arrivals:
If you pass the test mid-year, you file as a dual-status alien: a resident return (Form 1040) for the resident portion, with a statement covering the nonresident portion. Dual-status filing comes with two painful restrictions — no standard deduction, and no married-filing-jointly. Your US wages get taxed without the deduction that shelters the first $16,100 of income for a single filer in 2026. The mechanics, and why they sting, are covered in our dual-status filing guide.
The upside of dual-status: your Indian income from before you arrived — salary, interest, anything — stays off the US return. The US only taxes your worldwide income for the resident portion of the year.
If you're married, there's usually a better path than dual-status. Under §6013, a couple can elect to treat both spouses as full-year US residents and file jointly. That unlocks the full married-filing-jointly standard deduction — $32,200 for 2026 — and the friendlier joint tax brackets.
The trade-off is real: electing full-year residency means reporting worldwide income for the entire year, including the Indian salary you earned before moving. But taxes you paid in India on that income are generally creditable on Form 1116, which often wipes out most of the double-tax exposure. For many couples, the math favors the election comfortably; for a spouse with high pre-move Indian income and low Indian tax paid, it can go the other way. Run both versions before choosing.
One practical requirement: your spouse needs a taxpayer ID to file jointly. If they aren't eligible for an SSN, you'll attach a W-7 to the return — our ITIN guide for spouses and dependents walks through the certified-passport-copy route so you don't mail original documents.
The moment you're a US tax resident, two things follow that surprise almost every new H-1B arrival:
Also flag any Indian mutual funds you hold: for a US tax resident they're PFICs, a genuinely punitive regime that deserves its own attention before you file.
Your first-year H-1B return comes down to three decisions: when your residency started under the substantial presence test, whether dual-status or a full-year election gives the better result, and getting your Indian accounts onto the right disclosure forms from day one. Get those right and every later year is straightforward. Taxagon's CPAs and EAs prepare first-year and dual-status returns for new arrivals every season — if you'd rather not navigate the elections alone, our NRI tax team can take it from here.
