An Individual Taxpayer Identification Number (ITIN) is a tax processing number issued by the U.S. Internal Revenue Service (IRS). It is for certain non-resident and resident aliens, their spouses, and dependents who cannot get a Social Security Number (SSN). The IRS issues ITINs to individuals who need a U.S. taxpayer identification number but do not have, and are not eligible to obtain, an SSN. The term "California ITIN number" is a misnomer, as there is no such thing. The IRS is the only entity that issues ITINs, regardless of where the applicant resides in the United States or abroad.
If you searched for "what is california itin number," you are likely looking to understand how to obtain this number for tax purposes, especially if you have U.S. tax obligations. This guide will clarify what an ITIN is, who needs one, and the process for obtaining it through the IRS, dispelling the notion of a state-specific ITIN.
What Exactly is an ITIN?
An ITIN is a nine-digit number that begins with the number '9', has a '7' or '8' in the fourth digit, and ends with '4' (e.g., 9XX-7X-XXXX or 9XX-8X-XXXX). It is assigned to individuals who are required to have a U.S. taxpayer identification number for tax purposes but are not eligible for an SSN. This includes many foreign nationals who earn income in the U.S., are involved in a U.S. business, or need to file U.S. tax returns for other reasons. The ITIN is used solely for federal tax purposes and does not authorize employment in the U.S., provide eligibility for Social Security benefits, or grant any other immigration benefits.
Who Needs an ITIN?
Individuals who need an ITIN typically fall into several categories:
- Non-resident aliens filing a U.S. tax return: If you are a non-resident alien and have U.S. source income that requires you to file a federal tax return (such as a Form 1040-NR, U.S. Nonresident Alien Income Tax Return), you will need an ITIN to file. This can include income from investments, real estate, or business activities in the U.S.
- Resident aliens filing a U.S. tax return: While most resident aliens are eligible for an SSN, some may not be able to obtain one due to specific circumstances. In such cases, they may need an ITIN to file their U.S. tax returns.
- Dependents and beneficiaries: U.S. citizens or resident aliens who are married to or have a dependent who is not eligible for an SSN may need to obtain an ITIN for that individual if they are claimed on a tax return.
- Individuals with U.S. business interests: If you are involved in a U.S. business, such as owning a U.S. LLC, you might need an ITIN. For example, if your LLC is owned by foreign individuals who are not eligible for an SSN, they may need ITINs to report certain information, such as with Form 5472, Information Return of a 21% Foreign-Owned U.S. Corporation or a Foreign Corporation Engaged in a U.S. Trade or Business. Owning a U.S. LLC often necessitates obtaining an EIN (Employer Identification Number) for the business itself, which is a separate process from obtaining an ITIN for the individual owners. You can learn more about applying for an EIN on our /ein page.
- Individuals opening a U.S. bank account: While not all banks require an ITIN to open an account, some may ask for one, especially if you are a non-resident alien without an SSN. Having an ITIN can sometimes facilitate opening a U.S. bank account, which can be essential for managing business or personal finances in the U.S. Services like Mercury, Relay, or Brex are popular choices for non-residents needing business banking, and they often have specific requirements. Our /bank-account page provides more details.
The ITIN Application Process: Form W-7
The process for obtaining an ITIN involves completing and submitting Form W-7, Application for IRS Individual Taxpayer Identification Number. You cannot apply for an ITIN online or by phone. The application requires specific documentation to verify your identity and foreign status.
Required Documentation for Form W-7
To successfully apply for an ITIN, you must provide original or certified copies of documents that prove your identity and foreign status. The IRS accepts a variety of documents, but typically, applicants submit:
- Proof of Identity: A passport is the most commonly used and preferred document as it proves both identity and nationality. If a passport is not available, other documents like a national identity card, driver's license, birth certificate (for dependents under 18), or foreign military identification card may be accepted, often in combination with other forms of ID.
- Proof of Foreign Status: This is to confirm that you are a non-resident alien or meet other criteria for ITIN eligibility. Again, a passport is the primary document for this. If you are applying as a dependent, you may need to provide the applicant's birth certificate and the applicant's or your own passport.
The IRS has specific rules about which documents are acceptable and whether they must be originals or certified copies. If you submit original documents, the IRS will return them to you, but this can add significant time to the processing. Certified copies from the issuing agency or an authorized third party are generally preferred.
Submission Methods for Form W-7
There are three primary ways to submit your Form W-7 application to the IRS:
- Mail: You can mail your completed Form W-7, along with your original or certified supporting documents, directly to the IRS at the address specified in the Form W-7 instructions. Be aware that mailing original documents carries a risk of loss, and the IRS can take several weeks or even months to process your application and return your documents.
- IRS Taxpayer Assistance Centers (TACs): Some IRS TACs offer in-person assistance for ITIN applications. You can make an appointment at a TAC to have your documents verified. However, not all TACs provide this service, and you must check with the specific center beforehand. You will need to bring your original documents for verification.
- Through a Certified Acceptance Agent (CAA): This is often the most convenient and secure method. A Certified Acceptance Agent (CAA) is an individual or entity (like itin.net) authorized by the IRS to help taxpayers apply for ITINs. CAAs can verify your original documentation and forward your application to the IRS. The advantage of using a CAA is that they can certify your identification documents, meaning you do not have to send your originals to the IRS, reducing the risk of loss and often speeding up the process. This path is highly recommended for most applicants. You can find a CAA through the IRS website or by using services like ours, which offers a streamlined application process.
What to Expect After Submission
Once the IRS receives your completed Form W-7 and supporting documentation, they will review your application. If approved, the IRS will mail your ITIN to you on a Form CP-565, ITIN Assignment Letter. The processing time can vary significantly depending on the volume of applications the IRS is receiving. Currently, it can take anywhere from 7 to 11 weeks for the IRS to process a standard ITIN application submitted via mail or through a TAC. Applications submitted through a CAA may sometimes be processed more quickly.
If there are any issues with your application or documentation, the IRS will send you a notice explaining what needs to be corrected. It is crucial to respond to these notices promptly to avoid further delays or denial of your application.
Cost and Timeline Considerations
There is no fee charged by the IRS to apply for an ITIN. The Form W-7 application is free. However, if you choose to use the services of a Certified Acceptance Agent (CAA), they may charge a fee for their assistance in verifying your documents and processing your application. These fees vary by provider.
The timeline for receiving your ITIN is primarily dependent on the IRS processing times. As mentioned, this can range from 7 to 11 weeks or more. If you need an ITIN for a tax return that has a filing deadline, it is advisable to apply well in advance to account for potential delays. For example, if you are filing your U.S. tax return for the current year, you should aim to submit your ITIN application early in the following year.
Common Mistakes to Avoid
When applying for an ITIN, several common mistakes can lead to delays or rejection:
- Incomplete Application: Failing to fill out all sections of Form W-7 accurately and completely is a frequent issue. Ensure all required fields are addressed.
- Incorrect or Missing Documentation: Submitting documents that are not acceptable to the IRS, are expired, or are not properly certified can cause problems. Always refer to the latest Form W-7 instructions for the most up-to-date list of acceptable documents.
- Not Proving Identity and Foreign Status: Applicants must provide documentation that clearly establishes both their identity and their status as a non-resident alien (or other qualifying category). A single document may not suffice for both.
- Sending Copies Instead of Originals or Certified Copies: Unless you are using a CAA to certify your documents, you must send original identification documents or certified copies from the issuing agency. Photocopies are generally not accepted.
- Not Including a Tax Return (when required): In many cases, you must be filing a U.S. tax return to obtain an ITIN. If you are applying based on a tax return that is not included or is incomplete, your application may be denied. There are exceptions, such as for certain treaty benefits or third-party tax reporting, but a tax return is the most common basis for application.
What Happens After You Get Your ITIN?
Once you receive your ITIN on Form CP-565, you can use it for all your U.S. federal tax filing purposes. This includes filing your annual U.S. income tax return (Form 1040-NR for non-residents). If you are using your ITIN for business purposes, such as reporting income or filing informational returns like Form 5472 for a U.S. LLC, you will need to include it on those forms. Remember, an ITIN is not a substitute for an SSN and does not grant work authorization.
ITINs are generally valid for seven years from the date of issuance. However, if you do not use your ITIN on a federal tax return for three consecutive tax years, the IRS may begin to deactivate it. If your ITIN is deactivated, you will need to reapply using Form W-7 if you need it again. The IRS will notify you if your ITIN is scheduled for deactivation. Some ITINs assigned before January 1, 2013, have also expired and need to be renewed if they are still in use. You can check the IRS website for the latest ITIN renewal and expiration information.
