Why is ITIN processing a serious problem?

< Back to Q&A

The processing of IRS Individual Taxpayer Identification Numbers (ITINs) is a significant challenge for both taxpayers and tax professionals, and the reasons are rooted in the complexity of the rules, the documentation requirements, and the consequences of errors or delays. Understanding these issues is crucial for anyone who needs to know what an ITIN is, how to obtain an ITIN number, and the implications for tax compliance.

1. Complex Eligibility and Application Rules

The ITIN is a nine-digit tax processing number issued by the IRS to individuals who are required to have a U.S. taxpayer identification number but are not eligible for a Social Security Number (SSN). The ITIN number’s meaning is strictly for federal tax purposes; it does not authorize work in the U.S., provide eligibility for Social Security benefits, or serve as identification outside the tax system.

Eligibility for an ITIN is limited to individuals who have a federal tax filing requirement or are listed on a U.S. federal tax return for a valid tax purpose. For tax years 2018 through 2025, spouses and dependents are not eligible for an ITIN or to renew an ITIN unless they are claimed for an allowable tax benefit (such as the child and dependent care credit, credit for other dependents, or premium tax credit) or file their tax return.

2. Stringent Documentation Requirements

One of the most significant hurdles in ITIN processing is the documentation required to prove both identity and foreign status. Applicants must submit original documents or certified copies from the issuing agency. There are only 13 acceptable documents, and at least one must contain a recent photograph (unless the applicant is a young dependent). For dependents, a birth certificate is required unless a valid passport is submitted. If a passport is used, it must include a date of entry into the U.S. for certain dependents, or additional documentation to prove U.S. residency is required.

The requirement to submit original documents or certified copies can be a significant issue, particularly for applicants who need their documents for other purposes or are concerned about the risk of loss in transit. While in-person verification at IRS Taxpayer Assistance Centers or through Certifying Acceptance Agents is available, these options may not be accessible to all applicants, particularly those outside the U.S.

3. Delays and Processing Times

ITIN processing times are often lengthy. The IRS advises applicants to allow at least 7 weeks for notification of application status, and up to 11 weeks during peak periods or for applications from abroad. Delays can be even longer if the application is incomplete, if the documentation is unclear, or if additional information is requested. These delays can have serious consequences, such as missed tax filing deadlines, delayed refunds, or the inability to claim certain tax credits.

4. Strict Renewal and Expiration Rules

ITINs expire if they are not used on a U.S. federal tax return for three consecutive years. ITINs assigned before 2013 that have never been renewed are also considered expired. Using an expired ITIN on a tax return can result in processing delays and the denial of certain tax benefits until the ITIN is renewed. Renewal applications must also include a tax return unless an exception applies, adding another layer of complexity.

5. Impact on Tax Benefits and Compliance

A critical issue is the relationship between ITIN and EIC (Earned Income Credit). Taxpayers filing with an ITIN are not eligible for the EIC, and children with ITINs cannot be claimed as qualifying children for the EIC or, for tax years 2018–2025, for the Child Tax Credit or Additional Child Tax Credit. This can be confusing for taxpayers who may not understand why they are ineligible for these credits, leading to errors and potential audits.

6. Frequent Rejections and Resubmissions

Applications are often rejected due to incomplete forms, missing or incorrect documentation, or failure to meet eligibility criteria. Each rejection requires the applicant to resubmit the application, further delaying the process and increasing frustration. The IRS will not issue an ITIN if the applicant is eligible for an SSN, and a denial letter from the Social Security Administration is required in many cases.

7. Security and Fraud Concerns

The IRS has strict rules in place to prevent fraud, including revoking ITINs that were obtained or used fraudulently in connection with fraudulent refund claims. However, the process for revocation and reapplication can be complex and may impact individuals who need to comply with tax laws.

8. Administrative Burden for Taxpayers and Practitioners

The cumulative effect of these issues is a significant administrative burden. Taxpayers must navigate complex rules, gather and submit sensitive documents, and frequently encounter long wait times and repeated communications with the IRS. Tax professionals must stay current with evolving requirements and guide clients through a process that is prone to error and delay.

In summary:

ITIN processing is a significant issue due to the complex eligibility rules, strict documentation requirements, lengthy processing times, frequent rejections, and the substantial impact on tax compliance and access to tax benefits. For those seeking how to obtain an ITIN number, it is essential to carefully follow all instructions, provide complete and accurate documentation, and plan for potential delays. Understanding the meaning of the ITIN number and its limitations, particularly regarding credits such as the EIC, is crucial for compliance and avoiding unnecessary frustration or penalties.
