In the age of global business and cross-border opportunities, more and more non-U.S. residents—especially from India—are engaging with the U.S. economy. Whether you're investing in U.S. real estate, earning from U.S. platforms, or running a business incorporated in the United States, you may need one essential number to stay compliant with U.S. tax laws: the ITIN number.
If you're new to the U.S. tax system, this guide will help you understand what an ITIN is, who needs one, how to apply for it, and how a reliable partner like USAIndiaCFO can help simplify the ITIN application process from India.
What Is an ITIN Number?
An ITIN (Individual Taxpayer Identification Number) is a nine-digit tax processing number issued by the Internal Revenue Service (IRS). It’s designed for individuals who need to file or report taxes in the U.S. but are not eligible for a Social Security Number (SSN).
The format of an ITIN is similar to an SSN (e.g., 9XX-XX-XXXX), but it clearly indicates that the holder is a non-resident or foreign national.
Who Needs an ITIN Number?
You should apply for an ITIN if:
You are a non-resident alien required to file a U.S. tax return.
You are a U.S. company owner (LLC or C-Corp) who is not eligible for an SSN.
You are an Indian freelancer or consultant earning income from U.S. clients.
You are a spouse or dependent of a U.S. taxpayer (under certain conditions).
You are investing in U.S. real estate or stock markets and need to report gains/losses.
If any of these situations apply to you, then applying for an ITIN number is a crucial step for staying tax-compliant in the U.S.
Why Is an ITIN Important?
An ITIN allows you to:
File your U.S. federal income tax return.
Claim tax treaty benefits (e.g., lower withholding rates for Indian residents).
Receive refunds from the IRS if you’ve overpaid taxes.
Open a U.S. business bank account in some cases.
Fulfill IRS requirements as the owner of a U.S. LLC or C-Corp.
Without an ITIN, you may be subject to higher tax withholdings or even face penalties for non-compliance.
Difference Between EIN and ITIN
It’s common to confuse EIN and ITIN, but they serve different purposes:
EIN (Employer Identification Number): For businesses and entities. Used to file business taxes and open business bank accounts.
ITIN (Individual Taxpayer Identification Number): For individuals. Used to file personal taxes if you are not eligible for an SSN.
If you are a non-resident Indian who owns a U.S. business, you may need both an EIN (for the company) and an ITIN (for yourself as the individual member or director).
How to Apply for an ITIN Number from India
The ITIN application process is not available online. It must be done by submitting a paper application to the IRS. Here's a simplified breakdown of the process:
Step 1: Fill Out IRS Form W-7
You’ll need to complete Form W-7, which asks for:
Your personal details (name, address, date of birth, etc.)
Your U.S. tax filing reason (most applicants use “Non-resident alien required to get an ITIN to claim tax treaty benefits”)
Supporting documentation, such as your passport
Step 2: Provide Supporting Documents
Along with Form W-7, you must submit original documents or certified copies of your passport by the issuing agency. The IRS accepts:
Passport (most common)
National ID (with photo)
U.S. visa (if applicable)
It’s important that these documents are either originals or certified by the government agency that issued them—not just notarized copies.
Step 3: Submit Your Tax Return or IRS Letter
Most ITIN applications must be attached to a valid U.S. tax return (Form 1040-NR). In some cases, you may also be eligible to apply using an IRS notice or withholding document if you’re claiming treaty benefits.
This part often confuses first-time applicants. Thankfully, USAIndiaCFO can assist with this and ensure your submission is IRS-compliant.
Step 4: Mail Everything to the IRS
Send your W-7 form, documents, and tax return (if required) to:
Internal Revenue Service
ITIN Operation
P.O. Box 149342
Austin, TX 78714-9342
USA
You can also apply through a Certified Acceptance Agent (CAA) or U.S. Tax Professional, which is often faster and more secure—especially when working from India.
How Long Does It Take to Get an ITIN?
The IRS typically takes 6–12 weeks to process an ITIN application. However, delays are common if:
The form is incomplete or incorrect
The documents aren’t properly certified
The reason for ITIN isn’t clearly justified
Using a trusted service like USAIndiaCFO ensures that your application is submitted correctly, increasing your chances of quick approval.
