An ITIN renewal is generally needed only when an expired Individual Taxpayer Identification Number will be included on a U.S. federal tax return. For nonresidents, this often connects to Form 1040-NR, a treaty-based tax position, a refund claim, or another federal tax filing reason. An expired ITIN does not always need to be renewed right away. The main question is whether the number will be used on a federal return for a given tax year.
What an ITIN Is
An Individual Taxpayer Identification Number, or ITIN, is a tax processing number issued by the IRS. It is used by people who need a U.S. taxpayer identification number for federal tax purposes but do not have, and are not eligible to get, a Social Security number. The IRS explains this in its Form W-7 information page.
An ITIN is not a work permit. It does not give immigration status, Social Security benefits, or permission to work in the United States. It is mainly a federal tax identification number.
Nonresident aliens may see ITIN rules when they are connected to U.S.-source income, Form 1040-NR, treaty claims, withholding documents, or other tax reporting situations. Some international students, scholars, researchers, spouses, or dependents may also come across ITIN rules, depending on the facts.
When an ITIN Expires
The IRS states that an ITIN expires if it is not used on at least one U.S. federal tax return for three consecutive tax years. The number expires on December 31 after the third consecutive year of non-use. The IRS explains this rule on its ITIN renewal page.
The current Form W-7 instructions also state that an ITIN assigned before 2013 and never renewed must be renewed before it is used again on a U.S. federal tax return. Readers should check the current Instructions for Form W-7 for the filing year involved.
| Situation | General federal tax treatment |
|---|---|
| The ITIN will be used on a U.S. federal tax return | The ITIN may need to be renewed if it has expired. |
| The ITIN appears only on information returns, such as some Forms 1099 | The IRS says renewal is generally not required only for third-party information reporting. |
| The person is eligible for an SSN | Form W-7 should generally not be used. An ITIN is for people who are not eligible for an SSN. |
| The person previously had an ITIN but later received an SSN | The SSN should generally be used for future federal tax returns. |
| A spouse or dependent is connected to an allowable tax benefit | Renewal may depend on whether the person is listed on a federal return and the rules for that benefit. |
When a Nonresident May Need to Renew an ITIN
A nonresident may need to renew an ITIN when the expired number will be included on a U.S. federal tax return. This can include a Form 1040-NR filed to report U.S.-source income, claim a refund, or report income connected with a U.S. trade or business.
Some nonresident aliens may also need an ITIN for certain treaty-related tax positions. For example, Form W-7 includes a reason category for a nonresident alien who needs an ITIN to claim a tax treaty benefit. Treaty eligibility is fact-specific and should be checked against the relevant treaty article, IRS instructions, and the person’s documents.
International students and scholars may see ITIN renewal rules in limited situations. For example, an F-1 or J-1 student who is not eligible for an SSN may need an ITIN if a federal tax return or treaty-related tax process requires one. A student who is eligible for an SSN, such as through authorized employment, usually needs to follow SSN rules instead of applying for or renewing an ITIN.
When Renewal May Not Be Needed Yet
An expired ITIN does not always need immediate renewal. The IRS says that if an ITIN is used only on information returns filed by third parties, such as certain Forms 1099, renewal is not required only for that reporting use. If the person later files a federal income tax return using the ITIN, renewal may be needed at that time.
The IRS also states that an ITIN is not needed to request an extension or pay estimated tax. This matters for nonresidents who may make estimated payments with Form 1040-ES (NR) or request more time to file. The details should be checked in the relevant IRS form instructions for the filing year.
Form W-7 and the Renewal Process
Form W-7 is used both to apply for a new ITIN and to renew an existing ITIN. For renewal, the person generally checks the box for Renew an existing ITIN and completes the reason section that applies to the tax situation.
The IRS renewal instructions say that lines 6e and 6f should be completed when the applicant knows the existing ITIN. These lines ask whether the applicant previously received an ITIN and, if known, the number and the name under which it was issued.
- Use the current version of Form W-7 for the year of filing.
- Check the renewal box rather than the new application box.
- Select the reason that matches the federal tax purpose.
- Attach required supporting documents.
- Attach a federal tax return unless an IRS exception applies.
- Use the mailing or in-person process described by the IRS, not the regular tax return mailing address unless the instructions say so.
For most ITIN applications and renewals, the applicant must include a federal income tax return unless an exception applies. The IRS describes this process on its ITIN application page.
Documents Usually Involved
ITIN renewal requires documents that prove identity and foreign status. The IRS says supporting documents must generally be original documents or certified copies from the issuing agency, and they must be current when submitted. The IRS provides a list of acceptable documents on its ITIN supporting documents page.
A passport is often the only stand-alone document for identity and foreign status. If a valid passport is not used, the applicant may need to provide two documents, with at least one generally showing a photo, subject to IRS exceptions for certain dependents.
Some dependents have extra documentation rules, including proof of U.S. residency in certain cases. These rules can be narrow, so applicants should not assume that one document is enough without checking the current Form W-7 instructions.
Ways to Submit an ITIN Renewal
The IRS generally describes three routes for ITIN applications and renewals: by mail, through certain IRS in-person services, or with help from an IRS-authorized acceptance agent. Availability can vary by location and appointment schedule.
| Method | What it may involve | What to check |
|---|---|---|
| Form W-7, required documents, and any required federal tax return are mailed to the IRS address listed in the current instructions. | Use the address in the W-7 instructions, not a general tax return address. | |
| IRS Taxpayer Assistance Center | Certain locations may review or authenticate some documents by appointment. | Check available services and appointment rules before visiting. |
| Certifying Acceptance Agent | A CAA may help complete Form W-7 and authenticate many supporting documents. | Fees and services can vary. Confirm that the agent is IRS-authorized. |
| VITA site with ITIN services | Some VITA sites may have CAAs and may help with eligible tax return preparation. | ITIN services are not available at every VITA location. |
The IRS provides information about authorized help through its ITIN acceptance agents page. A Certifying Acceptance Agent may be able to authenticate many documents so that originals do not need to be mailed, but not every document or situation can be handled the same way.
Nonresident Examples
These examples are general and do not decide anyone’s filing duty. They show how ITIN renewal questions may arise for nonresidents.
Example 1: Expired ITIN and Form 1040-NR
A nonresident alien has an expired ITIN and expects to file Form 1040-NR for a tax year. If the ITIN will be included on that federal tax return, renewal may be needed before the return can be processed normally.
Example 2: ITIN Used Only on an Information Return
A person receives a third-party information return that includes an expired ITIN, but the person is not using the number on a federal income tax return for that year. The IRS says an ITIN used only on information returns does not need to be renewed for that purpose alone.
Example 3: International Student Not Eligible for an SSN
An international student who is not eligible for an SSN may need an ITIN if a federal tax filing or treaty-related process requires one. If the student already has an expired ITIN and will use it on a federal return, renewal may be part of the filing process.
Example 4: Student or Worker Eligible for an SSN
A person who is eligible for an SSN generally should not apply for or renew an ITIN. The IRS says Form W-7 should not be completed by someone who has an SSN or is eligible to get one. Once an SSN has been issued, the SSN should generally be used for future federal tax returns.
Common Mistakes and Misunderstandings
ITIN renewal mistakes often come from treating an ITIN like a general identity number. It is not. It is tied to federal tax administration.
- Renewing when no federal tax use exists: Renewal is generally tied to use on a federal tax return, not simply to having an expired number.
- Using Form W-7 despite SSN eligibility: People who have or are eligible for an SSN should review SSN rules instead.
- Sending regular copies of documents: The IRS generally requires original documents or certified copies from the issuing agency.
- Using the wrong mailing address: ITIN packages should follow the Form W-7 instructions.
- Forgetting the reason box: Form W-7 requires a reason for applying or renewing.
- Assuming all treaty claims work the same way: Treaty positions can depend on country, article, income type, form, and filing year.
How ITIN Renewal Connects to Other Nonresident Tax Terms
ITIN renewal is often connected to other nonresident tax terms. These terms can help readers understand why the number may be needed.
| Term | Plain English meaning |
|---|---|
| Nonresident alien | A person who is not treated as a U.S. resident alien for federal income tax purposes for the period involved. |
| Resident alien | A person treated as a U.S. tax resident under rules such as the green card test or substantial presence test. |
| Substantial presence test | A day-counting test used for federal tax residency. Some students and teachers may have special rules for certain years. |
| Form 1040-NR | The federal income tax return generally used by nonresident aliens who must file a U.S. nonresident return. |
| Form 8843 | A form often associated with certain exempt individuals, including some F, J, M, or Q visa holders, for federal tax residency reporting. |
| Form 1042-S | An information return often used to report certain U.S.-source payments to foreign persons, including treaty-related or scholarship payments. |
| FDAP income | Fixed or determinable annual or periodical income, such as certain interest, dividends, rents, royalties, or scholarships. |
| ECI | Effectively connected income, generally income connected with a U.S. trade or business. |
| Tax treaty | An agreement between the United States and another country that may affect how certain income is taxed. |
| Withholding | Tax held back by a payer before income is paid or credited. |
ITIN Renewal and State Tax
ITIN rules are federal IRS rules. State income tax rules are separate. A state may ask for identifying information on a state return, but state residency, state-source income, part-year resident rules, and filing duties are controlled by that state’s law.
A nonresident for federal tax purposes is not automatically a nonresident for every state tax purpose. Some states use different residency tests, domicile rules, or part-year resident rules. If an ITIN renewal affects a federal return, the person may still need to check the state tax agency instructions separately.
A Careful Pre-Filing Checklist
This checklist is educational and should not replace IRS instructions or professional review.
- Check whether the ITIN has expired under the three-year non-use rule or another IRS renewal rule.
- Confirm whether the ITIN will be included on a U.S. federal tax return for the year involved.
- Check whether the person has, or is eligible for, an SSN.
- Use the current Form W-7 and current instructions.
- Choose the correct reason for submitting Form W-7.
- Prepare required identity and foreign status documents.
- Attach the required federal return unless a specific IRS exception applies.
- Review any treaty, student, scholar, spouse, or dependent rule that affects the reason for the ITIN.
- Check whether state filing rules are separate from the federal ITIN process.

FAQ
Do nonresidents always need to renew an expired ITIN?
No. An expired ITIN generally needs renewal when it will be included on a U.S. federal tax return. If it is used only on third-party information returns, renewal may not be needed for that use alone.
Can a person renew an ITIN if they are eligible for an SSN?
Generally, no. The IRS says Form W-7 should not be used by someone who has an SSN or is eligible to get one. SSN eligibility should be checked with the Social Security Administration rules and the person’s status documents.
Does an ITIN allow a nonresident to work in the United States?
No. An ITIN is for federal tax purposes. It does not authorize work, provide immigration status, or create Social Security benefit eligibility.
Does Form W-7 always need a federal tax return attached?
In many cases, yes. The IRS generally requires a federal tax return with Form W-7 unless a listed exception applies. The current Form W-7 instructions should be reviewed before filing.
Can a nonresident renew an ITIN from outside the United States?
It may be possible to submit an ITIN renewal from outside the United States by following IRS procedures. The available method can depend on documents, mailing rules, and whether an IRS-authorized acceptance agent is available.
What happens if a federal return is filed with an expired ITIN?
The IRS says processing may be delayed, and some credits or refund-related items may be affected unless the ITIN is renewed. The result can depend on the return and the tax year.
