An ITIN, or Individual Taxpayer Identification Number, is a tax processing number issued by the Internal Revenue Service (IRS) for certain U.S. taxpayers who are not eligible for a Social Security number (SSN). It 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 ITIN is used for federal tax purposes, including filing tax returns and claiming tax benefits. You might need an ITIN if you are a non-resident alien, a resident alien, or a U.S. citizen who cannot obtain an SSN.
Who Needs an ITIN?
The IRS issues ITINs to individuals who have U.S. tax obligations but cannot get an SSN. This typically includes:
- Non-resident aliens who need to file a U.S. tax return, claim a treaty benefit, or meet other tax requirements. For example, if you receive U.S. source income and are required to file a tax return (like Form 1040-NR), you will likely need an ITIN. This is a common reason someone searches for "itin que significa?" – they have a U.S. tax filing requirement.
- Resident aliens (based on the substantial presence test) who are not eligible for an SSN. This might include individuals living in the U.S. who are on certain visas but do not qualify for an SSN.
- Dependents or spouses of U.S. citizens or resident aliens who cannot get an SSN.
- Dependents or spouses of non-resident alien visa holders.
- Individuals who are claimed as a dependent on a U.S. federal tax return.
An ITIN is not a work authorization document. It does not grant any employment privileges or benefits. It solely serves as a tax processing number.
How to Apply for an ITIN
Applying for an ITIN involves submitting Form W-7, Application for IRS Individual Taxpayer Identification Number. You must submit this form along with original or certified copies of your identification documents and a supporting U.S. federal income tax return. There are three primary ways to apply:
- Mail your application to the IRS: You can mail your completed Form W-7, your original or certified copies of identification documents, and your federal income tax return to the IRS address listed in the Form W-7 instructions. The IRS will review your application and supporting documents. They will then mail your original documents back to you and issue your ITIN. This process can take several weeks, and the IRS will keep your documents until processing is complete.
- Apply through a Certified Acceptance Agent (CAA): A CAA is an individual or business designated by the IRS to help taxpayers apply for ITINs. CAAs can verify your original identification documents and forward your Form W-7 application directly to the IRS. This is often a faster and more convenient method because you do not have to mail your original documents to the IRS. The itin.net ITIN application service, for instance, acts as a CAA, assisting applicants through this streamlined process.
- Schedule an appointment at an IRS Taxpayer Assistance Center (TAC): Some IRS TACs offer ITIN application services by appointment. You will need to bring your Form W-7, your identification documents, and your tax return to the appointment. You can find a list of participating TACs on the IRS website.
Regardless of the method chosen, you must submit a valid federal income tax return with your Form W-7 application. If you are applying for an ITIN to file a tax return for the current year, you will attach the Form W-7 to that return. If you are applying for an ITIN to claim a benefit under a tax treaty or for other reasons not related to filing a current tax return, you will need to include an "as if" tax return with your Form W-7.
Required Documentation for an ITIN Application
To apply for an ITIN, you must provide proof of your identity and foreign status. You need to submit original or certified copies of your identification documents. The most commonly accepted documents are:
- Passport: This is the preferred document as it establishes both identity and foreign status. If your passport does not show your current U.S. address, you will need to provide a separate document for address verification.
- National Identity Card: Must contain your name, photograph, address, date of birth, and expiration date.
- U.S. Driver’s License: Must contain your name, photograph, address, date of birth, and expiration date.
If you cannot provide a passport, you can use a combination of other documents to prove both identity and foreign status. For example, you might use a birth certificate (to prove identity) along with a foreign driver's license (to prove foreign status). A complete list of acceptable documents can be found in the Form W-7 instructions.
Crucially, the documents must be valid (not expired) and must include all the required information. If you submit certified copies, they must be certified by the issuing agency of the document (e.g., the Department of State or the agency that issued your passport).
Processing Time and Fees
The IRS does not charge a fee to apply for an ITIN. However, if you choose to use a Certified Acceptance Agent (CAA) like itin.net, they may charge a service fee for their assistance. This fee covers the agent's time and expertise in helping you prepare and submit your application correctly.
The IRS processing time for Form W-7 applications can vary. Generally, it takes the IRS between 7 to 11 weeks to process an ITIN application when submitted with a tax return. During peak tax seasons, processing times can be longer. If you submit your Form W-7 without a tax return (e.g., for treaty benefits), the processing time might be similar, but it's essential to follow the specific instructions for that scenario.
Using a CAA can sometimes expedite the process, as they can ensure the application is complete and accurate before submitting it to the IRS, potentially reducing the chance of delays due to errors. The IRS aims to issue ITINs within 11 weeks of receiving a complete application.
Renewing an ITIN
ITINs do not expire automatically. However, the IRS may require ITIN renewals for certain numbers. If your ITIN has not been used on a federal tax return for three consecutive tax years, it may expire. Additionally, the IRS has periodically issued notices requiring taxpayers with ITINs starting with specific middle digits to renew their ITINs. For example, in past years, ITINs starting with 70, 71, 72, 73, 74, 75, 76, 77, 81, 82, 83, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, or 95 have been subject to renewal.
If your ITIN has expired and you need it for tax purposes, you must renew it by submitting a renewed Form W-7 along with the required identification documents and a valid federal income tax return. The renewal process is similar to the initial application process. You can apply by mail, through a CAA, or at an IRS TAC.
It is important to keep your ITIN information updated with the IRS if your name or address changes. You will need to file Form W-7/N to report such changes.
Common Mistakes When Applying for an ITIN
Several common mistakes can lead to delays or rejections of your Form W-7 application. Being aware of these can help ensure a smoother process:
- Incomplete Tax Return: The most frequent error is submitting Form W-7 without a complete and accurate U.S. federal income tax return. Remember, an ITIN is primarily for tax processing, so a tax return is almost always required.
- Incorrect Personal Information: Ensure all names, addresses, and dates of birth on Form W-7 match exactly with your identification documents and tax return.
- Missing or Unacceptable Identification Documents: Not providing original or certified copies of required documents, or submitting documents that do not meet IRS criteria (e.g., expired IDs, documents missing required information).
- Not Using the Correct Form Version: Always use the latest version of Form W-7 and its accompanying instructions, available on the IRS website.
- Errors in the Tax Return: Mistakes in the attached tax return itself can also cause issues. Ensure your tax return is accurate and complete.
- Not Attaching Required Proof of Foreign Status: For certain applications, like those claiming tax treaty benefits, specific documentation proving foreign status and eligibility for the benefit must be included.
These mistakes can add weeks or even months to the process. Careful attention to detail and understanding the requirements are key.
ITIN vs. EIN: What's the Difference?
It is important to distinguish an ITIN from an Employer Identification Number (EIN), also known as a Federal Tax Identification Number. While both are issued by the IRS, they serve different purposes. An ITIN is for individuals who need a taxpayer identification number for tax purposes but cannot obtain an SSN. An EIN is a nine-digit number assigned to business entities operating in the U.S., such as corporations, partnerships, and LLCs. If you are forming a U.S. LLC or establishing a business presence in the United States, you will likely need an EIN, which is obtained by filing Form SS-4. You cannot use an ITIN to conduct business or open a U.S. bank account for a business; an EIN is required for these activities.
Next Steps After Obtaining an ITIN
Once you receive your ITIN, you can use it to file your U.S. federal income tax return. If your ITIN was issued for the purpose of opening a U.S. bank account as a non-resident, you can now proceed with that process. Many banks require an ITIN or EIN to open an account for non-residents. If you are establishing a business in the U.S., having an ITIN might be a preliminary step before obtaining an EIN for your business, or it may be required for certain personal tax filings related to that business. For individuals forming a U.S. LLC, obtaining an ITIN for personal tax filings related to the business might be necessary, alongside securing an EIN for the LLC itself.
Remember that an ITIN is specific to you as an individual. If you form a business entity like a U.S. LLC, that entity will need its own tax identification number, typically an EIN. You can learn more about obtaining an ITIN and related services on the itin.net ITIN application service. Understanding the purpose of an ITIN is the first step in complying with U.S. tax laws as a non-resident or foreign national.
