Introduction

The Individual Taxpayer Identification Number (ITIN) is a tax identification number issued by the IRS to individuals who need to interact with the U.S. tax or financial system but are not eligible for a Social Security Number. For non-residents, the ITIN is far more than a technical formality. It serves as a gateway to banking, credit, and compliance capabilities that are otherwise inaccessible.

The application process is simple and involves no tax obligations. Obtaining an ITIN does not require you to pay U.S. taxes, does not create any form of tax residency, and does not trigger any reporting requirements. It can be initiated from abroad, and a properly assembled file is usually approved within a few weeks.

Access to U.S. Banking

An ITIN is one of the most effective ways for non-residents to access U.S. personal banking. It is the key that enables you to open accounts at major institutions such as Bank of America or Chase and to access the full range of U.S. banking services.

U.S. banks offer the strongest cashback and reward programs in the world. Cardholders gain access to products with high benefits, including cashback rates that can reach 5% in specific categories, airport lounge access, travel credits, and a wide range of premium perks rarely available outside the United States.

Building a U.S. Credit Score

An ITIN also allows you to build a U.S. credit profile. Over time, this leads to a stronger credit score, which unlocks access to financial advantages such as:

• Access to premium credit cards with higher limits.
• Stronger cashback and reward programs.
• Preferential financing terms.
• Better treatment during financial verification processes.

Obtaining an ITIN

The easiest way to obtain an ITIN is to use an IRS-authorized service provider. These accredited agents verify your passport themselves, prepare the full application, and submit it directly to the IRS. This avoids sending your original passport and ensures the file is compliant. The cost generally ranges from 250 to 500 euros, depending on the provider.

You can also apply on your own by submitting Form W-7 together with a certified copy of your passport. The certification must be issued by a U.S. embassy or consulate, as the IRS does not accept standard notarizations or local certifications. Once submitted, an application processed without assistance usually takes several weeks.

Conclusion

If you want access to the best credit cards and reliable U.S. banking infrastructure, an ITIN is essential. It unlocks advanced banking features, enables the creation of a U.S. credit score, simplifies tax compliance, and strengthens your financial credibility within the U.S. ecosystem.
