What Is an ITIN?
An ITIN — Individual Taxpayer Identification Number — is a nine-digit number issued by the IRS to people who need to file a U.S. tax return but are not eligible for a Social Security Number. For Canadian casino winners, it is the key that unlocks a refund of the 30% withheld from their gambling winnings. Without a valid ITIN, the IRS cannot process your non-resident return or issue a refund.
At U.S. Tax Recovery, we handle the ITIN application on behalf of our clients as part of the complete refund process — so you never have to navigate IRS paperwork alone.
KEY TAKEAWAYS
- An ITIN is required to file a U.S. non-resident tax return and claim a gambling tax refund.
- You apply for an ITIN using IRS Form W-7, supported by certified identity documents.
- A Certified Acceptance Agent can verify your passport in-house — no mailing originals to the IRS.
- An existing ITIN may have expired if unused for three consecutive tax years.
Why Do Canadian Casino Winners Need an ITIN?
Canadian casino winners need an ITIN because the IRS requires a taxpayer identification number on every return it processes.
When a U.S. casino withholds 30% of your gambling winnings, that money goes directly to the IRS. To get it back, you must file IRS Form 1040-NR — the U.S. Non-Resident Alien Income Tax Return. That return cannot be submitted without a taxpayer identification number, and Canadians do not have a Social Security Number. The ITIN fills that gap.
If you have already received a Form 1042-S from the casino documenting the withholding, the next step before filing is confirming you have an active ITIN — or applying for one.
How Do You Apply for an ITIN?
You apply for an ITIN by completing IRS Form W-7 and submitting it with proof of foreign status and identity.
The application asks for basic personal information — your name, mailing address, country of citizenship, and the reason you need an ITIN. For Canadian casino winners, the reason is filing a U.S. non-resident return to claim a refund of withheld gambling tax.
Documents Required With Form W-7
The IRS requires documentation that proves both your identity and your foreign status. For most Canadians, a passport satisfies both requirements in a single document. The IRS accepts the following as standalone proof:
- Canadian passport (covers both identity and foreign status)
- Canadian driver’s licence combined with a national identity document
- Canadian provincial birth certificate combined with a foreign voter registration card
A passport is by far the simplest option. The critical issue is that the IRS requires either original documents or certified copies — not photocopies you certify yourself.
The Problem With Mailing Your Passport
If you apply for an ITIN on your own, you must mail your original passport to the IRS — and wait weeks or months to get it back. For most people, that is not practical. A lost or delayed passport can affect travel plans, border crossings, and any other identification needs during that period.
This is one of the most common reasons Canadian casino winners choose to work with a specialist rather than file alone.
What Is a Certified Acceptance Agent?
A Certified Acceptance Agent (CAA) is an individual or organization authorized by the IRS to verify identity documents on its behalf.
When you use a CAA, you bring your passport to them in person. The CAA examines the original document, completes a certification form, and submits it to the IRS alongside your W-7 application. Your original passport stays with you. You never mail it anywhere.
U.S. Tax Recovery is an IRS Certified Acceptance Agent. That authorization is not something every tax preparer holds — it requires a formal application, training, and ongoing compliance with IRS standards. It means our clients can complete the ITIN process without surrendering their travel documents.
ITIN Application: What to Expect
| Stage | What Happens | Typical Timeframe |
|---|---|---|
| Document review | CAA verifies your passport and completes certification | Same appointment |
| W-7 submission | Application mailed to IRS with your 1040-NR or standalone | Within days of appointment |
| IRS processing | IRS reviews and assigns ITIN | 7 to 11 weeks |
| ITIN issued | IRS mails ITIN letter to address on file | After processing completes |
Processing times can be longer during peak filing periods, typically January through April. Starting the process early reduces the chance of delays affecting your refund timeline.
Does Your Existing ITIN Still Work?
ITINs issued before 2013, or any ITIN that has not appeared on a U.S. federal tax return in three consecutive years, may have expired.
The IRS has been systematically expiring unused ITINs in batches. If your ITIN was issued several years ago and you have not filed a U.S. return since, there is a real possibility it is no longer active. Using an expired ITIN on a return causes the IRS to reject or delay processing. A renewal application — also filed on Form W-7 — is required before your refund claim can proceed.
If you are unsure whether your ITIN is still valid, a tax recovery specialist can confirm its status before you file and handle the renewal if needed.
Why Filing the ITIN Application Alone Is Harder Than It Looks
The W-7 form itself is not long, but the supporting documentation requirements are strict. A name that does not exactly match your passport, a document that does not meet IRS standards, or a missing certification can result in rejection and weeks of additional processing time.
Working with a Certified Acceptance Agent who handles these applications regularly means your W-7 is prepared correctly the first time. Combined with the ability to verify your identity documents in-house, it is the most efficient path to getting your ITIN and your refund without unnecessary delays or the risk of your passport being lost in the mail.
Frequently Asked Questions
Can I file for a gambling tax refund without an ITIN?
No. The IRS requires a valid taxpayer identification number to process any return, including a non-resident gambling refund claim. You can submit your W-7 application at the same time as your 1040-NR, but the IRS will not issue your refund until the ITIN has been assigned and verified.
How long does it take to get an ITIN?
The IRS typically processes ITIN applications in seven to eleven weeks when submitted with all required documentation. Applications filed during peak tax season may take longer. A complete, error-free submission through a Certified Acceptance Agent generally moves through the process faster than an incomplete or self-prepared application.
Does my ITIN expire if I stop visiting U.S. casinos for a few years?
Yes, potentially. An ITIN expires if it is not used on a U.S. federal tax return for three consecutive tax years. If you took a break from U.S. casino visits and did not file returns during that time, your ITIN may need to be renewed before you can submit a new gambling tax refund claim.
