Holding a work permit does not, by itself, make you a resident alien for tax purposes. The Employment Authorization Document gives you permission to work; it says nothing about how the IRS classifies you at tax time. That classification is decided by two specific tests, and your EAD is not one of them. Depending on your visa category and how long you have been in the United States, you may be a resident alien, a nonresident alien, or something in between.
How the IRS Decides Your Tax Residency
If you are not a U.S. citizen, the IRS starts with the assumption that you are a nonresident alien. You become a resident alien for a given calendar year only if you pass one of two tests.1Internal Revenue Service. Determining an Individuals Tax Residency Status
The Green Card Test
You pass this test if you were a lawful permanent resident at any point during the year. The IRS looks for a green card, not an EAD.2Internal Revenue Service. U.S. Tax Residency – Green Card Test If your work permit is bridging you to a green card you have not yet received, this test does not apply to you.
The Substantial Presence Test
This is the test that most often decides an EAD holder’s status. You pass it if you were physically in the United States for at least 31 days during the current year and at least 183 days across a three-year window, counted on a weighted formula:3Internal Revenue Service. Substantial Presence Test
- every day of presence in the current year counts in full
- each day in the previous year counts as one-third of a day
- each day two years prior counts as one-sixth of a day
Someone who has been living and working in the U.S. for a couple of years will almost certainly cross 183 days under this formula. A full calendar year of presence alone puts you well over the threshold before the prior years even factor in. So an EAD holder who has been here a while is, by default, headed toward resident alien status for tax purposes, regardless of what their immigration status looks like.
The Exceptions That Change the Answer for Many EAD Holders
The substantial presence test has carve-outs that matter enormously depending on which visa your EAD is attached to.
Exempt Individuals
Certain visa holders do not count their days of U.S. presence at all. The IRS calls them “exempt individuals,” which refers to the day-counting rule, not to tax-exempt income. The categories include foreign government personnel on A or G visas (except A-3 and G-5), teachers and trainees on J or Q visas, students on F, J, M, or Q visas, and professional athletes temporarily present for a charitable sports event.3Internal Revenue Service. Substantial Presence Test
This is the carve-out that catches most F-1 students on Optional Practical Training. Even though you are working full-time with your EAD and physically here every day, your days do not count toward the substantial presence test during your first five calendar years of U.S. presence. After five years, your days start counting normally and you will likely become a resident alien soon after.4Internal Revenue Service. Publication 519 (2025), U.S. Tax Guide for Aliens If you qualify as an exempt individual, you file Form 8843 with your return to document it.
Closer Connection to a Foreign Country
If you cross the 183-day line on the weighted formula but were in the U.S. fewer than 183 days during the current year itself, you may still be treated as a nonresident alien by showing a closer connection to a foreign country where you kept a tax home all year. To use it, you must have maintained a tax home abroad for the full year, have a closer connection to that country than to the U.S., and not have applied for or taken steps toward lawful permanent resident status.5Internal Revenue Service. Closer Connection Exception to the Substantial Presence Test
That last condition rules out a lot of EAD holders. If you filed Form I-485 to adjust status, you have taken a step toward permanent residency and cannot use this exception. The election is claimed on Form 8840, and missing the deadline can forfeit it unless you can show reasonable steps to learn about the requirement.
Tax Treaty Tie-Breaker
If you are a resident of both the U.S. and another country under each country’s domestic rules, a tax treaty between the two may contain a tie-breaker that assigns you to one country. If the treaty assigns you to the foreign country, the IRS treats you as a nonresident alien for income tax purposes even if you otherwise passed the green card or substantial presence test.4Internal Revenue Service. Publication 519 (2025), U.S. Tax Guide for Aliens You file Form 1040-NR with Form 8833 attached to disclose the treaty position.6Internal Revenue Service. Claiming Tax Treaty Benefits Failing to file Form 8833 when required carries a $1,000 penalty per failure.
What This Looks Like for Common EAD Situations
Because the EAD rides on top of an underlying visa or pending application, EAD holders in different situations land in very different places.
An F-1 student working on post-completion OPT with an EAD is typically still a nonresident alien during the first five calendar years of U.S. presence. The student exemption keeps those days from counting. Once year six begins, days start counting and the move to resident alien status happens quickly.
A worker with a pending Form I-485 who is using an EAD while waiting on a green card has usually been here long enough to pass the substantial presence test. That person is a resident alien for tax purposes, even though no green card has been issued yet, and the closer connection exception is off the table because the I-485 counts as a step toward permanent residency.
An asylum applicant who recently arrived and received an EAD may not yet have enough days of presence to pass the substantial presence test. That person remains a nonresident alien and is taxed only on U.S.-source income, even while working legally under the EAD.
What Changes When You Are a Resident Alien
Which side of the line you fall on controls almost everything about your filing.
Resident aliens file Form 1040, the same return a U.S. citizen uses, and report worldwide income. That includes foreign wages, interest on overseas bank accounts, rental income from property abroad, and investment gains in foreign markets.7Internal Revenue Service. Alien Taxation – Certain Essential Concepts This is the obligation that blindsides EAD holders who crossed into resident alien status through the substantial presence test without realizing it.
Nonresident aliens file Form 1040-NR and are taxed only on U.S.-source income or income connected to a U.S. trade or business.8Internal Revenue Service. About Form 1040-NR, U.S. Nonresident Alien Income Tax Return Income earned abroad generally stays outside the IRS’s reach.
Foreign Account Reporting
Resident alien status also switches on two foreign account reporting rules that do not apply to nonresidents.
FinCEN Form 114, the FBAR, is required if the combined value of your foreign financial accounts exceeded $10,000 at any point during the year. It is filed with the Financial Crimes Enforcement Network, not the IRS.9Internal Revenue Service. Comparison of Form 8938 and FBAR Requirements
Form 8938 is filed with your tax return. For an unmarried person living in the U.S., the threshold is foreign financial assets above $50,000 on the last day of the year or $75,000 at any point during the year. For a married couple filing jointly, those thresholds double to $100,000 and $150,000.9Internal Revenue Service. Comparison of Form 8938 and FBAR Requirements
If you have held foreign accounts for years with no U.S. reporting obligation, becoming a resident alien is the moment that changes.
FICA Withholding
Social Security and Medicare taxes are normally withheld from every paycheck, but nonresident aliens on F, J, and M visas whose work is authorized by USCIS and connected to the purpose of the visa are exempt.10Internal Revenue Service. Alien Liability for Social Security and Medicare Taxes of Foreign Teachers, Foreign Researchers and Other Foreign Professionals An F-1 student on OPT who is still a nonresident alien should not have FICA withheld. Once that student becomes a resident alien, FICA applies like it does for everyone else.
Employers sometimes withhold FICA from exempt workers in error. Ask the employer for a refund first; if the employer will not fix it, file a claim with the IRS using Form 843 and Form 8316.
What Happens If You File Under the Wrong Status
This is not just a paperwork question. Getting the classification wrong creates problems on both the tax and immigration sides.
Filing as a nonresident alien when you actually qualify as a resident alien usually means you have underreported income by leaving off foreign earnings. The IRS can assess a 20% accuracy-related penalty on the underpayment, plus interest from the original due date.11Internal Revenue Service. Accuracy-Related Penalty You would also have missed any FBAR and Form 8938 deadlines that applied, each with its own penalty regime.
On the immigration side, USCIS reviews tax returns during naturalization and asks on Form N-400 whether you have ever claimed to be a nonresident on a U.S. tax return. An incorrect nonresident filing can draw additional scrutiny or lead to denial. For green card holders, tax filings suggesting you were not residing in the U.S. can be treated as evidence that you abandoned permanent resident status.
Filing as a resident alien when you are actually a nonresident is less dangerous but still costly. You may have paid tax on income that was not taxable, or missed treaty benefits that would have reduced your withholding. Fixing it requires amended returns, and the window to reclaim FICA withheld in error is limited.
One practical point on identification: if your EAD authorizes you to work, you qualify to apply for a Social Security number.12Social Security Administration. Social Security Numbers for Noncitizens If you need to file a return but are not authorized to work, you apply for an ITIN on Form W-7. Having the right taxpayer identification number from the start avoids delays in processing your return and any refund you are owed.
