Five steps, and who does what
- Step 1 · You
Tell us about you
A short online form: who you are, where you live and why you need a U.S. tax number.
You'll need a valid passport and your U.S. tax reason.

- Step 2 · You and an agent
Video verification
On a video call, you show your documents to a Certifying Acceptance Agent. The agent verifies them and certifies copies for your application.
You'll need a phone or laptop with a camera, and your documents in hand.

- Step 3 · Nolly.com
We prepare and check your W-7
We fill in Form W-7 from your answers, and your U.S. tax return if you need one. Then we review everything before it goes anywhere.

- Step 4 · Nolly.com
We file with the IRS
We submit your application and tell you what to expect while the IRS reviews it.
- Step 5 · The IRS
The IRS mails your ITIN
The IRS reviews your application and mails you a letter with your ITIN. Timing is the IRS's: about 7 weeks, or 9–11 weeks in some cases (see below).

Four things to have ready
It's usually the only ID the IRS asks for. Spouses and dependants may need more.
For example U.S. rental income, selling U.S. property, income from U.S. platforms, or being a spouse or dependant on a U.S. return.
A phone or laptop for the video call with a Certifying Acceptance Agent.
Most applications go in with a federal return. Some qualify for an exception, and we'll tell you which applies.
How long the IRS takes
The IRS asks you to allow about 7 weeks. Applying from overseas, or between January 15 and April 30, takes 9 to 11.

Applying to the IRS is free. Here's what our fee covers.
If you're comfortable with the forms and can get your documents to the IRS, applying yourself is a good choice. If you'd rather have someone do it with you, that's what we're for.
