An Individual Taxpayer Identification Number (ITIN) is a tax processing number issued by the U.S. Internal Revenue Service (IRS) for certain non-resident and resident aliens, their spouses, and dependents who cannot get a Social Security number (SSN). The term "Indiana ITIN" is a misnomer; there is no such thing as a state-specific ITIN. An ITIN is a federal designation and is not tied to any particular state in the United States, including Indiana. If you are searching "what is indiana itin," you are likely looking for information on how to obtain an ITIN as a non-resident or foreign national who has U.S. tax obligations, regardless of your physical location or the location of your U.S. business interests.

What an ITIN Is and Is Not

An ITIN is a nine-digit number that always begins with the number "9" and has a "7" or "8" as the fourth digit (e.g., 9XX-7X-XXXX or 9XX-8X-XXXX). It is used solely for federal tax purposes. The IRS issues ITINs to individuals who are not eligible for an SSN but are required to have a U.S. taxpayer identification number. This includes individuals who:

Are non-resident aliens filing a U.S. federal tax return.
Are resident aliens (based on days present in the U.S.) filing a U.S. federal tax return.
Are dependents or spouses of U.S. citizens/resident aliens filing a U.S. federal tax return.
Are dependents or spouses of non-resident alien visa holders filing a U.S. federal tax return.
Are applying for an EIN (Employer Identification Number) for an entity they own or control, and the EIN application requires them to have an ITIN.

An ITIN is not a form of identification for employment or general identification purposes. It does not grant authorization to work in the United States, nor does it provide eligibility for Social Security benefits. It is purely for tax reporting and processing.

Why You Might Need an ITIN Without an SSN

Many non-residents and foreign nationals encounter situations requiring a U.S. taxpayer identification number even if they do not live or work in the U.S. full-time. Common scenarios include:

U.S. Source Income: Receiving income from U.S. sources, such as rental income from U.S. property, royalties, or dividends from U.S. companies. This income is often subject to U.S. tax withholding, and you may need to file a tax return (like Form 1040-NR) to claim treaty benefits or a refund, which requires an ITIN.
Filing U.S. Tax Returns: Even if you are a non-resident alien, if you have U.S. tax obligations, you will need to file a U.S. tax return. For example, if you sold U.S. real estate and had a gain, or if you were engaged in a U.S. trade or business, you must file. The Form 1040-NR (U.S. Nonresident Alien Income Tax Return) is the primary form for non-residents.
Opening a U.S. Bank Account: While some U.S. banks may allow non-residents to open accounts with just a foreign passport and an ITIN, others may require an SSN. If a bank requires a U.S. taxpayer identification number and you don't have an SSN, an ITIN can sometimes fulfill this requirement. This can be particularly useful for individuals or businesses planning to establish a U.S. bank account for operations or investments.
Form 5472 Filings for U.S. LLCs: Foreign individuals or entities who own a U.S. business, such as a U.S. LLC, are often required to file Form 5472 (Information Return of a 25% Foreign-Owned U.S. Corporation or a Foreign Corporation Engaged in a U.S. Trade or Business) along with a pro-forma Form 1120. This form reports transactions between the U.S. entity and its foreign owner. To file Form 5472, the foreign owner must have an ITIN or an SSN. Without an ITIN, you cannot properly report these transactions, which can lead to significant penalties.
Claiming Tax Treaty Benefits: If you are a resident of a country with a tax treaty with the United States, you might be eligible for reduced withholding rates on certain types of U.S. income. To claim these benefits, you typically need to file a U.S. tax return using an ITIN.

Who Issues an ITIN?

The IRS is the sole issuer of ITINs. You cannot obtain an ITIN from any other government agency or private entity. The IRS uses Form W-7 (Application for IRS Individual Taxpayer Identification Number) to process ITIN applications.

How to Apply for an ITIN

Applying for an ITIN involves completing Form W-7 and submitting it with original documentation or certified copies of your identification and foreign status. There are several ways to submit your application:

By Mail: You can mail your completed Form W-7, along with original or certified copies of your identification documents, directly to the IRS at the address specified in the Form W-7 instructions. This is the most common method but can have the longest processing times.
Through a Certified Acceptance Agent (CAA): This is often the preferred method as it simplifies the process. CAAs are individuals or entities (like itin.net) authorized by the IRS to help applicants. They can review your identification documents and forward your application to the IRS. A significant benefit of using a CAA is that they can certify your original identification documents (such as passports or birth certificates), meaning you do not have to mail your originals to the IRS. Instead, you submit copies to the CAA, who verifies them against the originals and forwards the certified copies with your W-7. This eliminates the risk of losing your original documents during mailing. itin.net is a service that provides assistance with the ITIN application process through its network of CAAs.
At an IRS Taxpayer Assistance Center (TAC): Some IRS TACs offer in-person ITIN application services by appointment. You must bring your original identification documents or certified copies. Appointments can be difficult to secure, and not all TACs provide this service.

Required Documentation for Form W-7

You must provide original or certified copies of documents proving your identity and foreign status. The most commonly accepted documents are:

Passport: This is the preferred document as it proves both identity and nationality.
National Identity Card: Must show name, photograph, address, date of birth, and expiration date.
U.S. Driver's License.
Foreign Driver's License.
U.S. State Identification Card.
Foreign Military Identification Card.
U.S. Military Identification Card.
Foreign Voters Registration Card.
Civil Birth Certificate (for dependents under 18).
Medical Records (dependents under 6).
School Records (dependents under 18).

If you cannot provide a passport, you must submit at least two other documents from the list to establish both identity and foreign status. The IRS provides specific rules for acceptable combinations of documents.

ITIN Processing Times and Costs

The IRS does not charge a fee to apply for an ITIN. However, if you use a service like itin.net to assist you through a Certified Acceptance Agent, there will be a fee for their services. This fee covers the agent's time, expertise, and the assurance of document handling.

The IRS processing times for ITIN applications can vary significantly. Currently, the IRS estimates the following processing times, though these are subject to change:

Mail-in applications: 7 to 11 weeks.
Applications submitted through a CAA: Typically faster, often processed within 4 to 6 weeks, as CAAs streamline the submission and initial review process.
Applications at IRS TACs: Can also be faster, but availability and appointment scheduling are significant factors.

These times are approximate and do not include mailing time to and from the IRS or potential delays if your application is incomplete or requires further review.

Common Mistakes to Avoid When Applying for an ITIN

Several common errors can lead to delays or rejections of your ITIN application:

Incomplete Form W-7: Ensure all fields are filled out accurately and completely. Missing information is a primary cause of delays.
Incorrect or Missing Identification Documents: Submitting documents that are expired, not certified, or not on the IRS's list of acceptable documents will cause your application to be rejected. Remember, if you are not using a CAA to certify your documents, you must mail original documents, which carry the risk of loss.
Not Linking to a Tax Return: If you are applying for an ITIN solely to file a tax return, your Form W-7 must be submitted with that tax return (or a statement explaining why you cannot attach it). If you are applying for other reasons (e.g., to open a bank account, for LLC reporting), you must state the specific exception category on Form W-7. Failing to do so will result in rejection.
Incorrectly Certified Documents: If using a CAA, ensure they are properly certifying your documents. If mailing originals, ensure they are indeed originals or certified copies from the issuing agency.
Not Renewing an Expired ITIN: ITINs that have not been used on a federal tax return for three consecutive tax years have been deactivated by the IRS. Additionally, ITINs starting with the digits 83 and 84, and 90, 91, and 92 have expired and must be renewed. If you need to use your ITIN for tax purposes, you must renew it by submitting Form W-7 with your tax return.

What Happens After You Get Your ITIN?

Once your ITIN application is approved, the IRS will mail you an official ITIN Assignment Letter (document number CP-565). This letter contains your unique ITIN. Keep this letter in a safe place, as you will need it for future tax filings and other official purposes.

If your ITIN was issued to allow you to open a U.S. bank account, you can now proceed with that process. If it was for U.S. LLC reporting (Form 5472), ensure you file the required forms by their deadlines. Remember that having an ITIN does not exempt you from U.S. tax obligations.

ITIN Renewal

As mentioned, the IRS has a policy of deactivating ITINs that are not used on a federal tax return for three consecutive years. Furthermore, ITINs issued before 2013 may expire based on their digits. If your ITIN has been deactivated or expired, you must renew it using Form W-7 and submitting it with a valid tax return. The renewal process is the same as the initial application, requiring proof of identity and foreign status. You can check your ITIN status on the IRS website or by contacting them directly.
