You landed in the US this year, found an apartment, and started a job. Now April is coming. Your first year tax filing status isn’t automatic. It depends on a specific counting formula. It has nothing to do with your visa type or how long you plan to stay. Get the status wrong and you could lose the standard deduction. You could also file a return the IRS flags for review. This guide walks through how that status actually gets decided.
Two arrivals with identical visas can land in different tax categories. A nurse who lands in February files differently than one who lands in November. The difference comes down to days physically present in the US, counted a specific way.
First Year Tax Filing Status: Resident or Nonresident Alien?
Every noncitizen who spends time in the US falls into one of two federal tax categories. You’re either a resident alien or a nonresident alien. The category determines which forms you file and what deductions you can claim.

Resident aliens generally file like US citizens, on Form 1040. They keep access to the standard deduction. Nonresident aliens file Form 1040-NR instead. They report only US-source income in most cases. They also lose the standard deduction entirely under current law.
Your green card, visa category, or job offer letter don’t decide this. The test is almost entirely about physical presence. It’s called the Substantial Presence Test, and it’s the backbone of first year tax filing decisions for nearly every new arrival.
How the Substantial Presence Test Actually Works
The Substantial Presence Test adds up days you were physically in the US, using a weighted formula. Current year days count in full. Days from the prior year count at one-third. Days from two years prior count at one-sixth. If that weighted total reaches 183, you meet the test.
For someone in their very first year, there are no prior-year days to add. So the entire calculation rests on days accumulated in the arrival year itself.
Someone who lands in February and stays through December could rack up 300-plus days easily. That clears 183 with room to spare. Someone who lands in late October has maybe 60 to 90 days left. That alone never reaches 183, so that person doesn’t meet the test for that year.
The IRS lays out the exact mechanics in Publication 519, including exempt individuals and excluded days. Don’t rely on rounded estimates from a blog post, including this one, to count your own days.
Why Arrival Timing Changes Your Filing Status
This is where first year tax filing gets confusing for new arrivals. Two people with the same visa can land in opposite tax categories. Timing, not paperwork, is the deciding factor.
Arrive in January through roughly June, and the math usually favors you. You likely accumulate enough days to meet the Substantial Presence Test that same year. You’d typically file as a resident alien for the full year, or something close to it.
Arrive in October, November, or December, and the math usually works against you. There simply aren’t enough days left to reach 183. Absent an election, that often makes you a nonresident alien for that partial year, with no standard deduction.
Neither outcome is wrong. Each is just the default result of the day-counting formula. What most late-year arrivals don’t realize is that the default isn’t the only option.
The First-Year Choice Election Most Newcomers Never Hear About
Buried in the tax code is a provision, IRC Section 7701(b)(4), commonly called the First-Year Choice election. It lets someone who misses the Substantial Presence Test in their arrival year elect resident treatment anyway, for part of that year.
The mechanics are specific. You generally need a minimum period of consecutive presence, at least 31 days in a row, within the arrival year. You then need to meet the Substantial Presence Test the following year. That happens once the following year’s days combine with the qualifying days from your arrival year.
Why bother? Resident treatment often opens the door to the standard deduction. It also brings different filing mechanics than a nonresident return allows. For someone who arrived in October with a modest salary, that difference can be worth real money.
This is not a box you check on a whim. The election requires specific statements attached to your return. Deadlines are tied to when you actually file, and interactions with treaty provisions vary by circumstance. Publication 519 covers the mechanical requirements, but the judgment calls around your specific dates are where people get it wrong.
Dual-Status Returns and First Year Tax Filing in Practice
Some new arrivals end up filing a dual-status return instead of a plain resident or nonresident return. This happens when your status genuinely changes partway through a calendar year.
A common pattern looks like this. You don’t meet the Substantial Presence Test in your arrival year, so that year defaults to nonresident. The following year, your days accumulate further and you meet the test partway through. That combination can produce a dual-status filing, splitting the year into a nonresident period and a resident period.
Dual-status returns carry their own quirks. Certain deductions get prorated. The standard deduction generally isn’t available for the nonresident portion. Filing deadlines and required statements also differ from an ordinary return.
None of this is intuitive from a standard tax software walkthrough. That’s why first year tax filing so often needs a human reviewing the actual dates involved. A program guessing your status from a few questions won’t catch every wrinkle.
Common First Year Tax Filing Mistakes to Avoid
The most frequent mistake is assuming there are only two options. People think it’s full resident or full nonresident, with nothing in between. Many new arrivals never learn the First-Year Choice election exists. So they default to whatever their tax software assumes from a few basic questions.
A second mistake is guessing at the day count instead of counting it. Overstating or understating days present changes which category you fall into. Sometimes you won’t even realize it happened.
A third mistake is confusing the Philippines-US tax treaty benefits available to green card holders with the residency test itself. Treaty provisions and residency status interact. But they answer different questions, and mixing them up leads to filing errors.
The last mistake worth naming is waiting until the deadline to sort any of this out. First-Year Choice carries timing requirements tied to when you file. Figuring out your status early gives you options a rushed filing doesn’t.
Given how easily a wrong assumption compounds, most new arrivals are better off with help. A CPA experienced with nonresident and first-year returns should review your specific dates. Treat this as a project worth paying for, not a do-it-yourself task.
FAQ
What determines first year tax filing status for new arrivals?
The Substantial Presence Test, a weighted count of physical-presence days across the current and two prior years. For a first-year arrival, only days in the arrival year count, since there’s no prior US presence yet.
Do I automatically become a resident alien after living in the US for a year?
Not automatically. Status depends on the day count reaching 183 under the weighted formula. It has nothing to do with the calendar anniversary of your arrival.
What is the First-Year Choice election?
A provision under IRC Section 7701(b)(4). It lets someone who misses the Substantial Presence Test in their arrival year elect resident treatment for part of it, given specific consecutive-presence and following-year conditions.
Can nonresident aliens claim the standard deduction?
Generally no. Nonresident alien returns filed on Form 1040-NR typically lose access to the standard deduction under current law. That’s one reason the First-Year Choice election matters for late-year arrivals.
Why does arrival month matter so much for tax status?
Because the Substantial Presence Test counts actual days present. Arriving early in the year leaves more months to accumulate the needed days. Arriving in October, November, or December often leaves too few days remaining.
Should I hire a professional for a first-year US tax return?
Given the day-counting mechanics and the election’s specific requirements, most new arrivals benefit from professional help. A CPA experienced with nonresident and first-year returns is worth the cost.
Quick Summary
- Your first year tax filing status depends on the Substantial Presence Test’s day count, not your visa type or how long you intend to stay.
- Late-year arrivals often default to nonresident status and lose the standard deduction, unless the First-Year Choice election under IRC Section 7701(b)(4) applies.
- Because the election and dual-status rules involve specific dates and conditions, a CPA experienced with first-year returns is worth the cost for most new arrivals.
