ITIN for International Students and Scholars
The honest answer is that most students on F-1, J-1 and M-1 do not need an ITIN — they need a Social Security number and do not realise they are eligible. Here is how to tell which one you are, before you spend three months on the wrong application.
Every rule on this page is cited to an IRS source, linked where it is used. Last read against those sources September 8, 2026.
If your F-1, J-1 or M-1 status lets you work — on-campus employment, a teaching or research assistantship, CPT or OPT — you are eligible for a Social Security number, and that is your number. The IRS will not issue an ITIN to anyone eligible for an SSN. An ITIN is right only when you have taxable U.S. money and no route to an SSN: typically a scholarship or fellowship above tuition and required fees, or treaty-exempt income a payer must report. Tick box f on Form W-7.
Key takeaways
- Employment beats everything. Any authorised campus job usually makes you SSN-eligible, which closes off the ITIN route entirely.
- The classic ITIN student is unfunded by work but funded by scholarship. The taxable part of that scholarship is the reason for the number.
- Form 8843 alone does not need a number. No income, no ITIN.
- Education credits closed to ITIN holders in 2026. Both the American Opportunity Credit and the Lifetime Learning Credit now require an SSN.
- Talk to your DSO or responsible officer first. They see this every semester and it costs nothing.
The answer for most students
This page exists partly because the search results for student ITIN questions skew toward pages that would rather sell you an application than tell you not to file one. Nothing here is for sale.
Which branch are you on?
| Your situation | SSN or ITIN? | Why |
|---|---|---|
| You have an on-campus job | Social Security number | On-campus employment is generally permitted incident to F-1 status, and permitted employment makes you SSN-eligible. Your international office can confirm and usually helps with the application. |
| You have a teaching or research assistantship | Social Security number | An assistantship is employment. The stipend is wages, reported on a Form W-2, and it needs an SSN. |
| You are on CPT or OPT | Social Security number | Both are authorised employment. If you do not already have an SSN, this is the moment to get one. |
| You have a J-1 programme that authorises employment | Social Security number | Same logic. The authorisation is what matters, not the visa letter. |
| Scholarship or fellowship above tuition and required fees, no job | ITIN | The excess over tuition and required fees is taxable, and the university has to report it. With no employment there is no SSN route, so this is a genuine ITIN case. |
| Treaty-exempt income a payer must report, no job | ITIN | The payer needs a number to apply the treaty rate and report the payment. This is one of the exception cases. |
| No U.S. income at all | Neither, usually | You may still need to file Form 8843 as a statement of your presence. That form does not require a taxpayer number. |

When an ITIN genuinely is the right number
Two cases dominate, and both are exception cases under Form W-7.
The taxable scholarship
A scholarship that covers tuition and required fees is generally not taxable. Amounts beyond that — room, board, travel, a living stipend — generally are. When a university pays a nonresident student taxable scholarship money it must report the payment and withhold, and it needs a taxpayer number to do so. If you have no employment and therefore no SSN route, that is your ITIN.
Treaty-exempt income
Many countries have tax treaties with the United States that reduce or eliminate U.S. tax on particular kinds of student and researcher income. To apply a treaty rate, the payer has to identify you — which means a number. This is the other main student exception.
The five exceptions, for reference
| # | Exception | Relevance to students |
|---|---|---|
| 1 | Passive income with third-party withholding or a treaty benefit | Applies if you hold U.S. investments that pay interest or dividends. |
| 2 | Wages, salary, scholarships, fellowships and grants | This is the student one — wages, scholarships, fellowships and grants, including cases where the Social Security Administration has declined to issue an SSN. |
| 3 | Third-party reporting of mortgage interest | Rarely relevant to a student. |
| 4 | Disposition of U.S. real property by a foreign person | Rarely relevant to a student. |
| 5 | Reporting obligations under Treasury Decision 9363 | Rarely relevant to a student. |

When it is a Social Security number instead
If you are eligible for an SSN, the ITIN route is closed — and that is good news, because an SSN does more.
- It is free, and your international office will usually walk you through it.
- It does not expire. An ITIN lapses after three consecutive years off a return.
- It reaches credits an ITIN cannot, including both education credits — which, since tax years beginning after 31 December 2025, require a Social Security number valid for work.
- It builds a record with the Social Security Administration, which matters if you stay and work in the U.S. later.
How a student applies
- Talk to your DSO or responsible officerBefore anything else. They will know whether your funding is employment (SSN) or a taxable scholarship (ITIN), and they see the distinction every semester. It costs nothing and it is the highest-value ten minutes in this process.
- Complete Form W-7, box fNonresident alien student, professor or researcher filing a U.S. tax return, or claiming an exception.
- Gather the documentsYour passport covers identity and foreign status on its own. Your current U.S. visa and your I-20 or DS-2019 will normally be part of the file too — check the current instructions for exactly what your reason code requires.
- Add either the tax return or the exception letterA return if you are filing one. If you are claiming the scholarship exception, the university's letter goes in instead.
- Submit — and use the campus route if there is oneMany universities have an arrangement with a Certifying Acceptance Agent, or run document-certification sessions in filing season. If yours does, that is usually the best route: your passport stays with you and someone who does this all day checks the form.
Full detail on the form, the documents and the routes is on the Form W-7 walkthrough, and the eligibility checker will build your document list.
Form 1040 or Form 1040-NR, and where Form 8843 fits
Which return you file is a separate question from which number you hold, and students routinely conflate them.
| Form 1040-NR | Form 1040 | |
|---|---|---|
| Who files it | Nonresidents for tax purposes — which most F and J students are during their exempt period | Residents for tax purposes, including students whose exempt period has ended and who then meet the day-count test |
| Standard deduction | Generally not available; a narrower set of itemised deductions applies instead | Available |
| Worldwide income | No — U.S.-source income only | Yes |
| Form 8843 | Filed alongside, as a statement of your days of presence | Not applicable once you are a resident |
What a student with an ITIN can and cannot claim
| Credit or deduction | Available to an ITIN filer? | Amount | Why |
|---|---|---|---|
| Child Tax CreditCHANGED | Up to $2,200 per child | You — or your spouse if you file jointly — must have a Social Security number valid for employment, and so must each qualifying child, issued before the return's due date. | |
| Credit for Other Dependents | $500 per dependent | This is the one that still works. The dependent may hold an SSN, an ITIN or an ATIN. It starts to phase out above $200,000 of adjusted gross income. | |
| Earned Income Tax Credit | — | The IRS states plainly that an ITIN does not qualify you for the Earned Income Tax Credit. Everyone on the return needs an SSN valid for employment. | |
| American Opportunity CreditCHANGED | — | New for tax years beginning after December 31, 2025: the person claiming the credit needs a Social Security number valid for work, and where the student is someone else, the student needs one too. | |
| Lifetime Learning CreditCHANGED | — | Same change, same date. An ITIN no longer supports either education credit. | |
| Child and Dependent Care Credit | Varies with expenses and income | This credit does not carry the SSN-valid-for-employment test that the Child Tax Credit does, so an ITIN filer can generally claim it if the ordinary rules are met. | |
| Itemized deductions and the standard deduction | Varies | A resident-alien ITIN filer takes the standard deduction like anyone else. A nonresident filing Form 1040-NR generally cannot, and itemizes a narrower list instead. | |
| The 2025-2028 deductions for tips, overtime, car loan interest and seniorsCHANGED | — | Each of these carries its own valid-Social-Security-number condition, so an ITIN filer cannot take them. |

Note also that nonresidents filing Form 1040-NR generally cannot take the standard deduction, which changes the arithmetic more than most students expect. Run it on the 2026 federal tax calculator.
After graduation: OPT, an SSN, and the switch
For most students, the ITIN is temporary. OPT is authorised employment, so it makes you eligible for a Social Security number — and the day that number is issued, the ITIN stops being your number.
- Stop using the ITIN immediatelyEvery form from that day forward carries the SSN. Never file with both.
- Write to the IRS to merge the recordsYour name, mailing address, ITIN, a copy of your Social Security card, and a copy of your CP565 notice. The IRS voids the ITIN and associates everything filed under it with the new number.
- Tell your employer and your universitySo the W-2 and the 1042-S for the year carry the right number. A form issued against the old number after the merge is how withholding goes missing.
The full procedure, the address, and what happens to your student-year filing history are on from ITIN to SSN.

Frequently asked questions
Do international students need an ITIN?
Most do not. If your F-1, J-1 or M-1 status permits you to work — on-campus employment, an assistantship, CPT or OPT — you are eligible for a Social Security number, and the IRS will not issue an ITIN to someone eligible for an SSN. An ITIN is the right number only when you have taxable U.S. money and no route to an SSN.
When does an F-1 student actually need an ITIN?
Chiefly when you have a scholarship or fellowship that exceeds tuition and required fees, so part of it is taxable, and you have no employment that would make you eligible for a Social Security number. Treaty-exempt income that a payer must report is the other common case. Both fall under the Form W-7 exceptions.
Do I need an ITIN to file Form 8843?
No. Form 8843 is a statement of your days of presence, not a tax return, and it can be filed without a taxpayer identification number if you have no U.S. income and no other reason for one. If you have no income at all, filing Form 8843 alone does not create a need for an ITIN.
Can I claim education credits with an ITIN?
No, not for tax years beginning after December 31, 2025. Both the American Opportunity Credit and the Lifetime Learning Credit now require a Social Security number valid for work, and where the student is claimed by someone else, the student needs one too. This changed under Public Law 119-21 and a lot of older guidance has not caught up.
My university asked for my ITIN. Should I apply?
Ask them first whether you are eligible for a Social Security number through your on-campus employment — many students are and do not realise it. If you genuinely are not eligible and the university must report a taxable scholarship to you, that is an exception case, and the university's letter is what goes in place of a tax return.
Does having an ITIN affect my student visa status?
The IRS states that an ITIN neither provides nor changes immigration status. It is a tax number. That said, anything touching your status is a question for your Designated School Official, your J-1 responsible officer, or an immigration attorney — not for a tax website, and not for a service selling ITIN applications.
As a student, do I file Form 1040 or Form 1040-NR?
Most F and J students are exempt individuals for a period of years, meaning their days do not count toward the substantial-presence test, so they file Form 1040-NR as nonresidents. After that exempt period, the ordinary day-count test applies and you may become a resident for tax purposes and file Form 1040. The two returns have different rules on deductions and credits.
When I get an SSN after graduating, what happens to my ITIN?
You stop using it immediately, and you write to the IRS asking it to void the ITIN and associate everything filed under it with your new Social Security number. Skip that step and the wages and withholding from your student years stay attached to a number the IRS no longer connects to you.
