Unlock Financial Success with Numbers Made Simple

An Individual Taxpayer Identification Number (ITIN) is a unique nine-digit tax identification number issued by the Internal Revenue Service (IRS) to individuals who are required to file U.S. tax returns but cannot obtain a Social Security Number (SSN). Whether you're an international student earning income, a foreign worker on a specialized visa, a non-resident investor, or a dependent with U.S. tax obligations, obtaining an ITIN is essential for legal tax compliance. Without an ITIN, you cannot file tax returns, report income to the IRS, or establish tax compliance history which can lead to penalties, compliance issues, and complications with future visa applications or immigration status. The IRS ITIN application requires precise documentation, proper form completion, and IRS submission through an approved Acceptance Agent.

NSKT Global steps in to simplify the process and ensure your application is approved on the first submission. Unlike generic online services that may miss critical documentation requirements, our team of certified tax professionals handles every aspect of your ITIN application. from initial eligibility assessment through final IRS submission and status tracking.

I have been working with Nikhil for ~a year now, and he has been immensely helpful. I came to him after another CPA firm made multiple errors in my tax submissions. After sorting that out he has further helped me to transition from a W-2 to a K-1, and helped me to discover additional areas of savings that I didn't realize I should have been receiving. He's also always prompt and professional.

Frequently Asked Questions About ITIN Applications

What is the difference between an ITIN and a Social Security Number (SSN)?

An ITIN is a tax identification number for individuals without SSNs who have U.S. tax obligations. An SSN is issued by the Social Security Administration to U.S. citizens, permanent residents, and authorized workers. ITINs are strictly for tax purposes and don't grant work authorization.

Can I apply for an ITIN without filing a tax return?

Yes, but it's uncommon. You can apply using Form W-7 alone if you have a specific tax reporting requirement. However, most people apply when filing their first U.S. tax return. Our team can assess your situation.

What if my ITIN expires? How do I renew it?

ITINs expire if not used on a tax return for three consecutive years. You can renew it using Form W-7. We help ensure timely renewal to avoid compliance issues.

How long does ITIN approval typically take?

The IRS generally processes ITIN applications within 4–6 weeks if everything is complete and correct. Properly prepared applications rarely face delays.

Do I need original documents or certified copies?

The IRS requires either original documents or certified copies with an apostille. Photocopies alone are not accepted. We guide you through proper documentation.

What if the IRS requests additional documentation?

If the IRS requests more information, we handle the response immediately. Our proactive process ensures such cases are rare.

Can I use my ITIN to open a bank account?

Yes. Many U.S. banks accept ITINs for opening accounts. You can also use it for credit cards and leasing. We can assist with required documentation.

Do I need an ITIN if I'm on an F-1 student visa?

If you earn income through employment, CPT/OPT, or scholarships, you need an ITIN to file taxes. We help students stay compliant.

Can I apply for an ITIN online?

No, ITIN applications cannot be filed online. They must be submitted in person or via an IRS-approved Acceptance Agent. We handle the full process for you.

Is there a fee for ITIN applications?

Yes, we charge a professional service fee depending on the service tier. This includes preparation, document review, submission, tracking, and follow-up support. The IRS does not charge an application fee.
