Yes, a person holding a valid Power of Attorney (POA) can apply for an Individual Taxpayer Identification Number (ITIN) on behalf of another individual, but the process is strictly governed by IRS rules and requires specific documentation beyond a standard POA document. The IRS does not accept a general POA for this purpose; the authorization must be explicitly for ITIN application purposes and meet the agency’s exacting standards for certification and notarization.
The core of the process revolves around submitting a complete and correct Form W-7, “Application for IRS Individual Taxpayer Identification Number.” For a POA to act, the submission must be accompanied by a certified POA document that is either:
- IRS Form 2848, Power of Attorney and Declaration of Representative.
- A foreign-sourced POA that has been certified by the issuing agency (like a consulate) and translated into English if necessary.
The critical point is that the POA document itself must grant the specific authority to apply for an ITIN. A generic POA used for managing bank accounts or property will almost certainly be rejected by the IRS. The table below outlines the key differences between a general POA and one acceptable for an ITIN application.
| Feature | General Power of Attorney | POA for IRS ITIN Application |
|---|---|---|
| Primary Purpose | Broad legal and financial management | Specifically authorizes applying for a tax ID with the IRS |
| IRS Acceptance | Typically rejected | Accepted if properly executed (e.g., Form 2848) |
| Documentation Required with W-7 | Not applicable | Original or certified copy of the POA, proof of foreign status, and identity documents for the applicant. |
| Certification Standard | Varies by jurisdiction | Must be certified by the issuing agency (e.g., U.S. consulate, foreign notary with apostille). |
Beyond the POA, the agent (the person holding the POA) must also ensure that all the standard ITIN application requirements are met for the principal (the person needing the ITIN). This includes providing original identification documents or certified copies from the issuing agency to prove identity and foreign status. The IRS is notoriously strict about documentation; photocopies or notarized copies of the original documents are not acceptable unless they are certified by the issuing agency. Common documents include a passport (which is the only standalone document accepted), national ID cards, and birth certificates.
The role of the Certifying Acceptance Agent (CAA) is crucial here. A CAA is an entity (like a bank, accounting firm, or other organization) authorized by the IRS to review original documents, certify that the copies are authentic, and submit the W-7 application package. For individuals residing outside the U.S., using a CAA can be a significant advantage, as it often avoids the need to mail precious original documents like passports to the IRS, which can be risky and time-consuming. The CAA can certify the copies and return the originals to the applicant. However, the POA agent must still ensure the CAA is provided with the certified POA and all other necessary paperwork. The entire process, from document gathering to mailing the application to the IRS Austin Service Center, can take several weeks, and processing times at the IRS can add another 7 to 11 weeks, according to recent data.
Let’s break down the typical data flow and responsibility in a POA-led ITIN application:
| Step | Action | Responsible Party | Key Documentation |
|---|---|---|---|
| 1. Preparation | Draft and execute a valid, IRS-acceptable POA. | Principal (with legal assistance) | Form 2848 or foreign POA certified by consulate. |
| 2. Document Collection | Gather original proof of identity and foreign status for the principal. | Agent (POA Holder) | Passport, national ID, birth certificate, etc. |
| 3. Certification (Optional but recommended) | Engage a Certifying Acceptance Agent (CAA) to verify original documents. | Agent (POA Holder) | All originals, certified POA, completed Form W-7. |
| 4. Submission | Mail the complete application package to the IRS. | Agent or CAA | Form W-7, certified POA, CAA certification (if applicable), tax return (if required). |
| 5. IRS Processing | Review, approve, and issue the ITIN via mail. | IRS | N/A |
It’s also vital to understand the “reason for applying” on the W-7 form. The most common reason for someone applying through a POA is that they have a filing requirement for a U.S. tax return but are not eligible for a Social Security Number (SSN). For example, a non-resident alien who needs to file a U.S. tax return to claim a treaty benefit or report income from U.S. sources would fall into this category. In such cases, the ITIN application (W-7) must often be submitted along with a completed U.S. tax return. The agent, acting under POA, would be responsible for ensuring the tax return is accurately prepared and filed with the application.
Potential pitfalls are numerous. Using an incorrectly drafted POA is the most common reason for rejection. Another major issue is submitting non-certified copies of identification documents. The IRS receives millions of ITIN applications and related documents annually; any deviation from their strict guidelines can result in a rejection letter, setting the process back by months. Furthermore, the agent must have a U.S. mailing address to which the IRS can send the ITIN and any correspondence. For principals living abroad, this often means the agent’s address becomes the address of record with the IRS, which has implications for future tax correspondence. Given these complexities, many individuals and agents seek professional assistance to navigate the labyrinth of requirements.

The legal authority granted by a POA in this context is specific and finite. It typically covers the act of applying for the ITIN and may include filing an associated tax return. It does not, unless explicitly stated, grant the agent the authority to use the ITIN for other purposes, such as opening bank accounts or conducting other business on behalf of the principal. The separation of these authorities is a critical safeguard. The IRS also has the right to revoke a POA’s authority if it finds the representative is not in compliance with tax laws or regulations. Data from tax practitioners suggests that applications involving a POA have a slightly higher scrutiny rate, underscoring the need for meticulous accuracy in the submission.
Finally, consider the scenario of a non-resident alien investor who owns rental property in the U.S. but lives in another country. This individual has a U.S. tax filing obligation to report rental income. They cannot get an SSN, so they need an ITIN. Since they cannot easily travel to a U.S. consulate or IRS office, they grant a POA to a trusted U.S.-based property manager or attorney. That agent then gathers the owner’s passport, has the POA certified by the local U.S. consulate, works with a CAA to avoid sending the original passport overseas, and submits the W-7 with the owner’s first tax return. This real-world example illustrates the practical necessity and complexity of the POA process for ITIN acquisition, a process that intertwines international law, U.S. tax policy, and practical logistics.
