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 ITIN is a nine-digit number that always begins with the number 9 and has a 7 or 8 in the fourth digit (e.g., 9XX-7X-XXXX or 9XX-8X-XXXX). The IRS issues ITINs solely for tax purposes. It does not provide any benefit or authorization for work, nor does it confer eligibility for Social Security benefits. Many individuals who search "what us itin" are seeking to understand their U.S. tax obligations when they do not qualify for an SSN. This is common for foreign nationals who have U.S. tax reporting requirements, such as filing U.S. income tax returns or reporting certain business activities, but are not eligible for an SSN.
Who Needs an ITIN?
You need an ITIN if you are a non-resident alien or a resident alien who does not have and is not eligible to obtain an SSN, and you have a U.S. tax filing requirement or are claiming a tax treaty benefit. Common scenarios include:
- Non-resident aliens with U.S. source income: If you earn income from U.S. sources (like rent from U.S. property, or certain business income) and are not a U.S. citizen or eligible for an SSN, you likely need an ITIN to file your U.S. tax return (Form 1040-NR).
- Dependents and spouses of U.S. citizens or resident aliens: If you are a dependent or spouse of a U.S. citizen or resident alien and do not qualify for an SSN, you may need an ITIN for the U.S. citizen or resident alien to claim certain tax benefits, such as the child tax credit or education credits.
- Individuals filing U.S. tax returns for other reasons: This can include individuals who need to file a U.S. tax return to claim a refund or to satisfy other U.S. tax law requirements.
- Individuals establishing U.S. business entities: Foreign nationals who form a U.S. LLC or other business entity may require an ITIN for themselves if they have personal U.S. tax obligations related to that business. While the business itself might need an EIN (Employer Identification Number), the individual owner's tax status and obligations are separate and may necessitate an ITIN. Forming a U.S. LLC is a common step for foreign entrepreneurs, and understanding the associated tax identification requirements is essential. This often involves obtaining both an EIN for the business and potentially an ITIN for the individual owners if they are not U.S. residents eligible for an SSN.
- Individuals opening a U.S. bank account: While not always strictly required by banks, some financial institutions may request an ITIN from non-residents who do not have an SSN when opening a U.S. bank account. This is particularly true for accounts that might have U.S. tax reporting implications. Some banks and fintech services, like Mercury, Relay, or Brex, have specific requirements for non-residents without SSNs, and an ITIN can facilitate the process.
Eligibility for an ITIN is based on your need to comply with U.S. tax laws, not on your immigration status or ability to work in the United States.
What is the Purpose of an ITIN?
The primary purpose of an ITIN is to facilitate the proper identification of taxpayers who are required to have or choose to obtain a U.S. taxpayer identification number but are not eligible for an SSN. It allows the IRS to track tax filings and payments efficiently.
Key functions and implications of an ITIN include:
- Tax Filing: It is essential for filing federal income tax returns (Form 1040-NR for non-residents, or Form 1040 for resident aliens). Without it, you cannot accurately report your U.S. income or claim any deductions or credits you may be entitled to.
- Tax Treaty Benefits: If you are a citizen of a country with a tax treaty with the United States, you may need an ITIN to claim reduced withholding tax rates on certain types of U.S. income, such as dividends or royalties.
- Reporting Requirements: It is used for various other IRS reporting requirements, such as filing Form 5472 for certain foreign-owned U.S. corporations or U.S. LLCs that have a single foreign owner. This form is crucial for reporting transactions between the U.S. entity and its foreign owner and carries significant penalties for non-filing.
- Refund Claims: If you have overpaid U.S. taxes and are due a refund, you will need an ITIN to file a return to claim it.
- Not for Employment: An ITIN does not authorize you to work in the United States. A separate work authorization document and an SSN are required for employment.
- Not for Social Security Benefits: An ITIN does not qualify you for Social Security benefits. Eligibility for Social Security benefits is tied to earning sufficient credits through U.S. employment, which requires an SSN.
Understanding these distinctions is vital for anyone asking "what us itin" and considering their U.S. tax obligations.
How Do You Apply for an ITIN?
Applying for an ITIN involves submitting Form W-7, Application for IRS Individual Taxpayer Identification Number, along with original or certified copies of identification documents and a valid U.S. federal income tax return. You cannot apply for an ITIN without filing a tax return, unless you qualify for a specific exception.
The general process is as follows:
- Complete Form W-7: Fill out the form accurately and completely. You will need to provide your name, address, foreign tax identification number (if applicable), and information about your tax return.
- Attach a Valid U.S. Federal Income Tax Return: This is the most common requirement. You must attach a tax return for which the ITIN is needed. For example, if you need an ITIN for the current tax year, you attach the current year's tax return. If you need it for a prior year's return, you attach that prior year's return. There are exceptions, such as for certain treaty benefits or when applying on behalf of a dependent, where a tax return may not be required.
- Provide Proof of Identity and Foreign Status: You must submit original or certified copies of your identification documents. The most commonly accepted documents are a passport or a national identity card. Other documents may include a birth certificate, a foreign driver's license, or a foreign military identification card. Each document must contain your name, photograph, current address, and date of birth. If you cannot provide a passport, you will need to submit a combination of other documents to meet these requirements.
- Choose an Application Method: You have several options for submitting your Form W-7 application:
- Mail: You can mail your completed Form W-7, along with your tax return and original or certified identification 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 will keep them until your ITIN is assigned, which can take several weeks or months.
- IRS Taxpayer Assistance Center (TAC): You can make an appointment at certain IRS TACs to have your identity and foreign documents verified in person. You must bring your original documents or certified copies. Not all TACs offer this service, so you should check with the specific location.
- Certified Acceptance Agent (CAA): This is often the most convenient and secure method. CAAs are individuals or entities (like itin.net) authorized by the IRS to assist applicants in obtaining ITINs. CAAs can authenticate your identification documents, meaning you can submit copies to the IRS without sending your originals. This significantly reduces the risk of losing valuable personal documents. Using a CAA streamlines the process and can help ensure your application is complete and accurate from the start. If you are considering forming a U.S. LLC or need an EIN for your business, a CAA can often assist with those processes as well, providing a comprehensive solution for your U.S. business needs.
What Identification Documents Are Required?
To apply for an ITIN, you must provide documentation that proves both your identity and your foreign status. The IRS requires a combination of documents, with a valid, unexpired passport being the preferred and most straightforward option. If a passport is not available or does not meet all requirements, a combination of other documents may be used.
Each document submitted must contain:
- Your name
- Your photograph
- Your current address
- Your date of birth
Here are the acceptable documents, categorized by the IRS:
- Primary Identification Document (must include photograph):
- Passport (U.S. or foreign)
- National Identity Card (must contain name, photograph, address, DOB, and expiration date)
- U.S. Driver's License
- Foreign Driver's License
- U.S. Military Identification Card
- Foreign Military Identification Card
- U.S. Permanent Resident Card (Green Card)
- Foreign Voter's Registration Card
- Secondary Identification Documents (used in combination if a primary document does not meet all requirements):
- Original or certified copy of a Birth Certificate (if you do not have a passport)
- Foreign national identification card (without photo)
- National identification card from your country of citizenship
- State identification card (U.S.)
- Civilan I.D. card (U.S.)
- Health insurance card
- Homeowners insurance policy
- Voter registration card (foreign)
- School records (foreign)
- Bank statements (foreign)
- Utility bills (foreign)
- Consular identification card
The IRS has specific rules about which documents can be combined if you are not submitting a passport. For example, if you are using a birth certificate to prove identity and foreign status, you must also submit a secondary document that includes your photograph and confirms your identity. When using a Certified Acceptance Agent (CAA), they can help you determine the correct documentation and verify it without you needing to send your original documents to the IRS.
What is the Processing Time and Cost?
There is no fee to apply for an ITIN directly with the IRS. The Form W-7 application is free. However, if you use a Certified Acceptance Agent (CAA), they may charge a fee for their services. These fees vary by agent but are generally reasonable for the convenience and security they provide, such as authenticating your documents to avoid mailing originals.
Processing times can vary significantly and are subject to change based on IRS workload. Generally:
- By Mail or TAC: When applying by mail or at an IRS Taxpayer Assistance Center (TAC), the IRS estimates processing can take up to 11 weeks from the date they receive your application. This timeframe does not include the time it takes for your tax return to be processed.
- Via CAA: Applications submitted through a CAA often have a slightly faster turnaround for initial verification by the CAA, but the ultimate processing time by the IRS remains the same. The benefit of using a CAA is primarily in the accuracy of the application and the security of your original documents.
It is crucial to apply well in advance of any tax deadlines, especially if you are filing your tax return at the same time. Missing a tax deadline due to ITIN processing delays can result in penalties and interest. If you are seeking an ITIN to open a U.S. bank account or establish a U.S. LLC, it is advisable to plan for these processing times. Similarly, if you require an EIN for your business, the application process for that is separate and has its own timeline, though it can often be obtained more quickly than an ITIN.
Common Mistakes When Applying for an ITIN
Many applicants make common errors that can delay or result in the rejection of their Form W-7 application. Being aware of these pitfalls can help ensure a smoother process.
- Missing or Incorrect Tax Return: The most frequent mistake is not attaching a complete and accurate U.S. federal income tax return, or attaching the wrong year's return. Remember, you generally need to file a tax return to get an ITIN, unless you qualify for an exception. Ensure the tax return is signed and dated.
- Incomplete Form W-7: Errors or omissions on the Form W-7 itself are common. This includes missing information in required fields, incorrect names (especially if they differ from your identification documents), or incorrect addresses. Double-check all details against your supporting documents.
- Invalid Identification Documents: Submitting documents that do not meet the IRS criteria for identity and foreign status is a frequent issue. This could be providing expired documents, documents without a photograph when one is required, or documents missing essential information like your address or date of birth. Ensure your documents meet the strict requirements outlined by the IRS.
- Not Sending Original or Certified Copies: If you are mailing your application directly to the IRS, you must send original identification documents or certified copies from the issuing agency. Copies certified by a notary public are generally not accepted. This is why using a Certified Acceptance Agent (CAA) is highly recommended, as they can verify your documents without you having to mail them.
- Incorrect Application Method: Some applicants try to apply for an ITIN without filing a tax return, or they attempt to use a method not supported by the IRS for their specific situation.
- Incorrect Social Security Number Field: Applicants may mistakenly enter an SSN they believe they are eligible for, or leave the SSN field blank when they should indicate they are not eligible. The W-7 specifically asks about SSN application history.
Carefully reviewing the instructions for Form W-7 and considering assistance from a CAA can help prevent these errors.
What Happens After You Get Your ITIN?
Once your ITIN application is approved, the IRS will mail you an official notification letter, Letter CP-565, which contains your ITIN. This letter is important documentation, so keep it in a safe place. You will then use this ITIN for all your U.S. tax-related activities.
- Tax Filing: Use your ITIN on all future federal tax returns. If you filed your initial return with your application, you will receive any refund due after that return is processed.
- Business Filings: If you are involved in a U.S. LLC or other business that requires an EIN, you will use the EIN for business tax filings, but your ITIN will be used for any personal tax reporting related to that business income.
- Banking: If you obtained an ITIN to open a U.S. bank account, you can now finalize that process or use your ITIN for any other financial services that require it.
- ITIN Renewal: ITINs that have not been used on a federal tax return for three consecutive tax years expire. Additionally, the IRS has a program to renew ITINs that begin with the digits 70, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, or 98. If your ITIN falls into one of these categories and has not been renewed, it will not be accepted for tax filing. You must renew your ITIN by submitting a valid tax return with your application. The renewal process is similar to the initial application, requiring Form W-7 and proof of identity and foreign status. The IRS typically announces renewal periods and instructions on its website.
- Other IRS Notices: You may receive other IRS notices related to your tax filings, such as CP-48 (Notice to Applicant for ITIN) if there are issues with your application, or CP-575 (Notice of SSN Assignment) if you are later issued an SSN (in which case your ITIN is no longer valid for tax purposes).
It is essential to keep your ITIN information current with the IRS. If your name changes, you will need to submit documentation to update it with the IRS. Failure to do so can complicate your tax filings. For individuals who are uncertain about these processes, seeking assistance from a tax professional or a CAA is a wise step.
