ITIN for Non-Residents — Complete 2026 IRS Form W-7 Application Guide
Obtain your Individual Taxpayer Identification Number securely from anywhere in the world. Unlock US markets, comply with tax laws, and scale your business without a Social Security Number.
Quick Answer
Non-US residents can obtain an Individual Taxpayer Identification Number (ITIN) from the IRS without an SSN or US visit. An ITIN is only needed for a personal US tax filing obligation — such as filing Form 1040-NR, claiming tax treaty benefits, or resolving backup withholding. HynoGo prepares Form W-7 with verified passport documentation through an IRS-authorized Certified Acceptance Agent (CAA), so you never have to mail your original passport to the IRS.
Common Myth: “I need an ITIN to form an LLC or open a US bank account”
This is false. Non-residents do NOT need an ITIN to form a US LLC or open a US business bank account. An EIN (Employer Identification Number) for your LLC, combined with your foreign passport, is sufficient for Mercury, Wise Business, Relay, and Stripe. An ITIN is a separate, personal tax ID only needed if you have an individual US tax filing requirement — see the ITIN vs EIN comparison below.
Why Non-Residents Need an ITIN
IRS Form 1040-NR Filing
Foreign owners of a US Single-Member LLC must file Form 1120 and Form 5472. Additionally, if your LLC has US effectively connected income (ECI), you'll need an ITIN to file a personal tax return (Form 1040-NR) and report your earnings to the IRS.
Amazon Seller Account Verification
To sell on Amazon US, you need a tax identity. Providing an ITIN completes the mandatory tax interview and ensures your income is correctly documented, preventing arbitrary withholdings on your payouts.
Stripe Identity Verification
When setting up a robust US payment gateway like Stripe, an ITIN verifies your personal identity as the business owner, facilitating KYC (Know Your Customer) compliance and unlocking payout features for Stripe for non-residents.
US Real Estate Tax Withholding
Foreign investors in US real estate need an ITIN to claim tax treaty benefits or process exemptions under FIRPTA when selling property, ensuring you aren't subject to the standard 15% withholding on gross sales.

The 6-Step ITIN Application Walkthrough
1. Tax Reason Determination
We analyze your situation to determine the exact IRS exception category for your application, ensuring the IRS accepts your W-7 filing reason.
2. Document Preparation
HynoGo prepares the official IRS Form W-7 on your behalf, ensuring all foreign address formats and legal names match precisely.
3. Passport Certification via CAA
HynoGo works with an IRS-authorized Certified Acceptance Agent (CAA) who verifies your original passport in person or remotely and certifies the copy submitted to the IRS — the alternative is mailing your original physical passport to the IRS Austin, TX processing center and going without it for weeks.
4. Application Review & Signature
You review the final documents and provide your physical signature on the W-7 form, ready for submission to the tax authorities.
5. IRS Submission
HynoGo packages your signed Form W-7, certified passport copy, and supporting exception documents, mailing them directly to the specialized IRS ITIN Operations unit in Austin, Texas.
6. Wait for IRS Processing
The IRS processes the application. Upon approval, you receive a physical ITIN assignment letter (Notice CP565) issued by the US government.
Processing Timeline & Delays
The standard IRS processing timeline for an ITIN application is 7 to 11 weeks.
It is crucial to understand that unlike an EIN, an ITIN cannot be expedited. Processing times may extend up to 14 weeks during peak tax season (January through April). Missing documents, incorrect formatting, or improper passport certification are the leading causes of application rejection or extensive delays.
