You cannot directly "look up" an existing ITIN number online. The IRS does not provide a public lookup tool for ITINs. An ITIN is assigned to an individual taxpayer and is confidential information. If you have lost your ITIN or need to confirm it, you must request it directly from the IRS. This article explains the methods available to retrieve or confirm your ITIN, and outlines the process for obtaining a new one if necessary.
Confirming Your Existing ITIN
If you have previously been issued an ITIN and need to confirm it, the IRS offers a few methods. These are the only official ways to verify your ITIN. The process involves proving your identity and providing specific information related to your previous tax filings.
Requesting Your ITIN from the IRS
To confirm your ITIN, you must contact the IRS directly. You can do this by mail or by phone. The IRS will not provide this information via email or through third-party websites. Be prepared to provide personal identifying information to verify your identity.
By Mail: You can send a written request to the IRS service center where you filed your most recent tax return. Your request must include your full name, current address, and your Social Security number (if you have one). You must also include a copy of a government-issued identification document. The IRS recommends sending this request via certified mail to track its delivery.
By Phone: You can call the IRS toll-free at 800-829-1040. This line is for individual taxpayers. You will need to answer security questions to verify your identity. These questions are typically related to information from your previous tax returns, such as filing status, adjusted gross income, or dependents. This is often the fastest way to confirm your ITIN if you can pass the identity verification.
IRS Notice CP565: If you were issued an ITIN, the IRS sends a notice called CP565 which contains your ITIN. If you still have this notice, it serves as official confirmation. If you cannot find it, you will need to use the methods above to request confirmation.
What if You Never Received Your ITIN?
If you applied for an ITIN and believe you never received it, or if you cannot locate the CP565 notice, you must follow the procedures for confirming an existing ITIN. It is important to note that the IRS does not typically send out duplicate CP565 notices. Therefore, contacting the IRS by phone or mail is your primary recourse.
What Information is Needed for Confirmation?
When you contact the IRS to inquire about your ITIN, you will need to provide several pieces of information to facilitate the lookup. This ensures that your identity is verified and that the IRS can locate your record.
- Full Legal Name: As it appears on your identification and previous tax filings.
- Current Mailing Address: The address where the IRS can send you correspondence.
- Date of Birth: To confirm your identity.
- Previous Tax Return Information: If you have filed taxes before, information such as the tax year, filing status, and adjusted gross income can be helpful.
- Government-Issued Identification: A copy of your valid passport, driver's license, or national identity card may be required if you are requesting information by mail.
It is important to have as much of this information readily available as possible. The more details you can provide, the easier it will be for the IRS representative to locate your taxpayer identification record.
How to Obtain a New ITIN
If you discover that you have never been issued an ITIN, or if your previous ITIN has expired and you need a new one for tax filing purposes, you must apply for one. The process for obtaining a new ITIN is different from simply looking up or confirming an existing one. This involves submitting a Form W-7, Application for IRS Individual Taxpayer Identification Number.
The ITIN Application Process (Form W-7)
The Form W-7 is used by individuals who are not eligible for a Social Security Number (SSN) but need a U.S. taxpayer identification number. This includes non-resident aliens who must file a U.S. tax return or claim a tax treaty benefit. The application requires supporting documentation to verify identity and foreign status.
Steps to Apply for a New ITIN:
- Complete Form W-7: Fill out the Form W-7 accurately and completely. Ensure all required fields are addressed. You will need to provide your full name, address, date of birth, and information about your U.S. tax filing requirement.
- Gather Supporting Documentation: You must submit original documentation or certified copies from the issuing agency that prove your identity and foreign status. Common documents include a valid passport, national identity card, or driver's license.
- Choose an Application Method: There are three primary ways to submit your Form W-7 and supporting documents:
- Mail to the IRS: Send your completed Form W-7, original or certified documents, and your U.S. federal income tax return to the IRS address listed on the Form W-7 instructions. This is the most common method but can have the longest processing times.
- Through a Certified Acceptance Agent (CAA): You can apply through a CAA, which is an individual or business authorized by the IRS to help taxpayers apply for ITINs. CAAs can verify your original identification documents and forward your application to the IRS. This service, offered by companies like itin.net, can expedite the process by reducing the need to mail original documents. The CAA reviews your application and documents, then sends them to the IRS for processing.
- At an IRS Taxpayer Assistance Center (TAC): Some IRS TACs offer ITIN application services by appointment. You must call the IRS to schedule an appointment and bring your original documentation. Availability can be limited.
Processing Times for New ITIN Applications
Processing times for a new ITIN application can vary significantly. The IRS typically states that it can take up to 11 weeks from the date of submission to receive your ITIN. However, during peak tax seasons or periods of high application volume, these times can extend. Applying through a CAA may offer a slightly faster turnaround for the initial verification step, but the final assignment of the ITIN is still handled by the IRS.
Common Reasons for ITIN Application Rejection
Understanding common pitfalls can help ensure your application is processed without delay. A rejected Form W-7 means you will have to reapply, causing further delays in obtaining your ITIN.
- Incomplete Application: Missing information on the Form W-7 is a frequent cause of rejection. Ensure all required fields are filled out accurately.
- Insufficient Documentation: Not providing valid, original, or certified copies of identification and foreign status documents is a major reason for rejection. If you mail original documents, they will be returned to you. If you use a CAA, they verify your documents and send copies. Always check the IRS guidelines for acceptable documentation.
- Incorrect Tax Filing Requirement: You must demonstrate a valid tax reason for needing an ITIN. This is usually by attaching a U.S. federal income tax return (e.g., Form 1040-NR for non-residents) to your Form W-7. If the tax return is not filed correctly or is missing, the ITIN application will be denied.
- Expired Identification: Ensure all identification documents submitted are valid and have not expired.
ITIN Renewal Requirements
While not all ITINs expire, some do. An ITIN that has not been used on a federal tax return for three consecutive tax years will expire. Additionally, ITINs with middle digits between 70-88 and 89 were set to expire starting in 2022. If your ITIN falls into these categories or has not been used, you will need to renew it by submitting a Form W-7 and a tax return. The renewal process is the same as applying for a new ITIN.
When to Consider Professional Assistance
Navigating U.S. tax laws and application processes can be complex, especially for non-residents. If you are unsure about your eligibility, the required documentation, or how to complete the forms, seeking professional assistance is highly recommended. This is where services like itin.net can be invaluable. A Certified Acceptance Agent can guide you through the application, verify your documents, and help ensure your submission is complete and accurate, significantly reducing the risk of delays or rejections. This is particularly helpful when you need to understand how to look up itin number, as professionals can help you access IRS resources or reapply efficiently.
For more complex situations, such as those involving U.S. business formation, obtaining an Employer Identification Number (EIN) for your company, or opening a U.S. bank account, consulting with a tax professional or legal advisor is advisable. These services are often intertwined, and establishing a U.S. presence may require multiple steps, including obtaining an EIN via Form SS-4 if you are forming a U.S. LLC, or securing a U.S. bank account. For readers planning to start a U.S. business, understanding the need for an EIN is a crucial next step after considering an ITIN.
If you are an international individual or entity planning U.S. operations, understanding the ITIN process is fundamental. Whether you need to confirm an existing number or apply for a new one, following the IRS procedures is key. For those who find the process daunting, utilizing services that specialize in ITIN applications can simplify the journey. Remember, the IRS does not offer an online lookup tool for ITINs; direct contact or application through authorized agents are the only avenues available.
