How to Get an ITIN: Everything You Need to Know

What Is an ITIN?

If you earn money in the United States but don’t qualify for a Social Security Number, you’ll need an ITIN — an Individual Taxpayer Identification Number. This number helps non-U.S. residents stay compliant with U.S. tax rules, file returns, and receive refunds. At Nolly.com, we make ITIN applications simple, secure, and accurate. Here’s how to get an ITIN step by step.

An ITIN is issued by the IRS for people who must file a U.S. tax return but aren’t eligible for a Social Security Number. It’s used for tax purposes only — not for work authorization or immigration.
You may need an ITIN if you:

  • Receive income from U.S. property or investments
  • Sell U.S. real estate and need a FIRPTA refund
  • File a 1040NR tax return as a non-resident
  • Are a dependent or spouse of a U.S. taxpayer
  • Operate a business that receives U.S. income

Step 1: Complete IRS Form W-7

The first step is filling out Form W-7, the official IRS application for an ITIN. This form asks for your name, address, country of citizenship, and the reason you need the number. Make sure every section is complete, and check the correct reason box — for example, “Non-resident alien filing a U.S. tax return.”

Step 2: Gather Identification Documents

You must prove your identity and foreign status. The easiest way is with a valid passport. If you don’t have one, the IRS accepts other documents, such as a national ID card, driver’s license, or birth certificate. All documents must be current and clearly legible.

Step 3: Include a Tax Document

The IRS requires proof of why you need an ITIN. This is usually a tax form such as:

  • 1040NR (U.S. Non-Resident Tax Return)
  • 8288-B (FIRPTA withholding certificate)
  • A letter from a U.S. withholding agent

Including this supporting document is crucial. Many ITIN applications are rejected because this step was missed.

Step 4: Verify Your Identity

You can verify your identity in two ways.
If you apply directly with the IRS, you must mail your original passport or visit a tax office in person. This can be risky or inconvenient.
With a Certified Acceptance Agent (CAA) like Nolly.com, your identity is verified securely online. You keep your passport, and we handle the verification process directly with the IRS.

Step 5: Submit Your Application

Once verified, your application is sent to the IRS for review. Processing usually takes six to ten weeks. At Nolly.com, we monitor every submission and notify you when your ITIN is approved.

Step 6: Receive and Use Your ITIN

Your ITIN will arrive by mail from the IRS. You can now use it to file taxes, claim refunds, and handle any U.S. income reporting. Keep your ITIN in a safe place. If you don’t use it for three years, it will expire and must be renewed.
