If you are a nonresident alien preparing Form 1040-NR, one of the most important details is the taxpayer identification number. If you do not have a Social Security number and are not eligible for one, you may need an Individual Taxpayer Identification Number, also called an ITIN. This guide explains what may happen when Form 1040-NR is filed without an ITIN, how Form W-7 fits into the process, and how in-person help from a Certified Acceptance Agent in Pittsburgh may help you avoid common filing issues.
What Happens If a Nonresident Alien Files Form 1040-NR Without an ITIN?
If a nonresident alien files Form 1040-NR without an ITIN and does not properly include Form W-7 when an ITIN is needed, the return may be delayed or require IRS follow-up. Form 1040-NR is used by nonresident alien individuals, estates, and trusts to file a U.S. income tax return. The IRS also states that Form W-7 is used to apply for or renew an ITIN when someone needs a taxpayer identification number for federal tax purposes but does not have and is not eligible for an SSN.
A Form 1040-NR without an ITIN is not automatically handled the same way in every case. The key question is whether the filer properly requested an ITIN with the return. If an ITIN is needed, the IRS instructions say applicants must include a U.S. federal tax return unless they meet an exception, along with the required documentation.

Can the IRS Process a Return While an ITIN Is Being Requested?
Yes, the IRS can receive an ITIN application package that includes both Form W-7 and the federal tax return connected to the ITIN request. The IRS explains that an ITIN application package generally includes Form W-7, a U.S. federal income tax return, and documents proving identity and foreign status, unless an exception applies.
This is why many first-time ITIN applicants do not wait to receive an ITIN before preparing the tax return. Instead, the return and Form W-7 are submitted together so the IRS can review the ITIN request and the tax filing package in the same process.
However, IRS processing return while ITIN is requested does not mean the applicant can ignore the taxpayer ID issue. The Form W-7 package must still be complete. If the W-7 is missing, the identity documents are unacceptable, or the return is not attached when required, the IRS may request more information or reject the ITIN application.

What Problems Can Happen If the Taxpayer ID Section Is Wrong?
A wrong taxpayer ID on Form 1040-NR can create processing problems because the IRS needs to connect the return to the correct taxpayer record. If the filer has an SSN, that number is usually used. If the filer is not eligible for an SSN but has a federal tax purpose, an ITIN may be needed instead. The IRS states that ITINs are issued for federal tax purposes and do not authorize work in the United States, provide Social Security benefits, or change immigration status.
Common taxpayer ID problems include:
- Leaving the taxpayer identification area unresolved
- Using an incorrect or expired ITIN
- Applying for an ITIN even though the person is eligible for an SSN
- Filing Form 1040-NR without attaching Form W-7 when a new ITIN is needed
- Using a different name on Form W-7, Form 1040-NR, and identity documents
- Sending copies that are not original documents or certified copies from the issuing agency
These issues can slow down the filing and create avoidable back-and-forth with the IRS. If you are unsure whether you need an ITIN or SSN, see Can a nonresident alien file U.S. taxes without a Social Security number?
How Can Nonresident Aliens Reduce ITIN Filing Delays?
Nonresident aliens can reduce ITIN filing delays by reviewing the full package before submission. The IRS says ITIN applicants must provide documentation that proves identity and foreign status. Applicants can submit Form W-7 by mail with original documents or certified copies, schedule an appointment at certain IRS Taxpayer Assistance Centers while in the United States, or use a Certifying Acceptance Agent.
Before submitting Form W-7 with Form 1040-NR, review:
- Whether you are eligible for an SSN
- Whether Form 1040-NR is the correct return
- Whether Form W-7 is complete and signed
- Whether the tax return is attached unless an exception applies
- Whether identity and foreign status documents meet IRS rules
- Whether your name, date of birth, and citizenship match across all documents
- Whether you are applying for a new ITIN or renewing an existing one
A Certified Acceptance Agent may help reduce confusion during this review. The IRS says Certifying Acceptance Agents can help complete Form W-7, authenticate most supporting documents, return authenticated documents, mail the ITIN package, and work with the IRS on application issues.
