Move to the US mid-year and you're likely a dual-status alien: nonresident, then resident. Here's how the split return works, its restrictions, and the MFJ election that often beats it.
Move to the US partway through the year and you'll probably file the strangest return of your life: a dual-status return — nonresident for the months before your residency started, resident for the months after. One tax year, two sets of rules, stitched together on a Form 1040 with a statement attached.
Dual-status filing works, but it carries two harsh restrictions — no standard deduction and no joint filing — which is why the §6013 full-year election is often the better route for married couples. This post covers the mechanics, the restrictions, the election math, and the First-Year Choice. It's part of the arrival-year picture in The NRI's Complete Guide to US Taxes.
You're dual-status in any year your residency starts or ends mid-year. For new arrivals, residency typically starts on your first day of presence once you satisfy the substantial presence test — 31 days minimum and 183 weighted days, a formula we work through in our substantial presence test guide. Arrive July 1 and cross the threshold, and you're a nonresident January through June, a resident July through December.
Arrive late in the year — say October — and you may not reach 183 days at all, leaving you a nonresident for the entire year by default. That's where the First-Year Choice comes in, below.
The two halves of the year are taxed on different bases:
Mechanically, a new arrival who ends the year as a resident files Form 1040 marked "Dual-Status Return," with a statement — usually a Form 1040-NR — attached to report the nonresident-period income. (Someone leaving the US permanently files the mirror image: 1040-NR with a 1040 statement.)
For a single filer with modest pre-move income, these restrictions may cost little — dual-status can genuinely be the right answer. For married couples, they're usually the reason to elect out.
If you're married and at least one spouse is a resident at year-end, §6013(g)/(h) lets you both elect to be treated as full-year US residents and file a joint return. The gains are immediate:
The price: both spouses report worldwide income for the entire year — including everything earned in India before the move. The usual counterweight is the foreign tax credit on Form 1116 for Indian tax paid on that income. When Indian tax on the pre-move income was substantial, the credit absorbs most of the added US tax and the election wins comfortably. When the pre-move income was lightly taxed — NRE interest, income under India's exemption limits — the election adds real US tax, and you have to run the numbers both ways. There's no universal answer; there is always a computable one.
Practical note: a joint return needs a taxpayer ID for both spouses. A spouse without an SSN applies for an ITIN by attaching Form W-7 to the return — the process, documents, and timing are in our ITIN guide for spouses and dependents.
Arrive too late to pass the substantial presence test — say, an October arrival with roughly 92 days — and you're a nonresident for the whole arrival year by default. The First-Year Choice election lets you start residency from your arrival date anyway, provided you meet presence requirements in the arrival year and go on to satisfy the substantial presence test in the following year.
The catch is timing: you can't make the election until you've actually qualified in year two, which often means filing an extension for the arrival-year return and filing it later. Why bother? Because First-Year Choice makes you dual-status for the arrival year — and for a married couple, dual-status is the doorway to the full-year §6013 joint election. The two elections stacked together are the standard play for late-year H-1B arrivals with a spouse, a pattern we cover from the visa side in our first-year H-1B tax guide.
Whichever route you take, becoming a resident brings reporting obligations along with it: FBAR (FinCEN 114) once foreign accounts exceed $10,000 in aggregate, and Form 8938 at its higher thresholds. If you make the full-year election, treat the disclosure question with the same full-year seriousness. These forms are informational — but the penalties for skipping them dwarf most people's actual tax.
The year you move, you'll land in one of three filings: a default dual-status return, a full-year joint return via the §6013 election, or a nonresident year bridged by the First-Year Choice. The right one depends on your arrival date, marital status, and how heavily India taxed your pre-move income — and it's worth computing all viable options before filing. Taxagon's CPAs and EAs prepare dual-status and election-year returns every season — if this is your arrival year, our NRI tax team can run the comparison for you.
