什麼是ITIN？如何申請與使用由美國國稅局（IRS）所發 ITIN（個人納稅人識別號碼）
What is an ITIN (Individual Taxpayer Identification Number)?
An ITIN is issued by the Internal Revenue Service (IRS) to people who aren't eligible for a Social Security number (SSN), typically foreign nationals, or individuals who can't provide qualifying identity documentation. It's a nine-digit number and, like an SSN, it's used for filing taxes and other tax purposes.
What an ITIN is for
- Filing taxes
This is its primary purpose. If you work in the US and can't get an SSN, you file using an ITIN. - Opening a bank account
In some cases banks will accept an ITIN to open an account, particularly for non-citizens without an SSN. - Building credit
Some lenders or credit card companies may also allow you to use an ITIN to build a credit history, helping you establish credit in the US.
Who can apply
- People ineligible for an SSN: foreign nationals, and their spouses or children.
- People with a US tax obligation: lawful resident aliens, and foreign nationals working in the US.
How to apply
- Complete Form W-7
Start with the IRS's Form W-7, downloadable from the IRS website (IRS Form W-7 download）。 - Provide identity documentation
You'll need valid identity documentation, such as a passport. The IRS requires the original or a certified copy. - Submit the application
Mail the completed W-7, your identity documents, and any other required materials to the designated IRS address. You can also file through an IRS-authorized Acceptance Agent. - Wait for processing
Usually, the processing time for an ITIN application is 6 to 8 weeks, and your ITIN will be sent to you by mail.
ITIN vs SSN
- SSN (Social Security number): for US citizens and lawful residents, covering Social Security benefits, tax filing, and employment.
- ITIN: for tax filing only. It confers no Social Security benefits and no work authorization.
Common misconceptions
- An ITIN is not work authorization
Having one doesn't let you work in the US. You still need proper work authorization. The ITIN is purely a tax identifier. - An ITIN is not immigration status
It says nothing about your legal status. It's an identification number for tax filing, nothing more.
Why it matters
- An ITIN is your key tool for filing taxes legally in the US. If you don't have an SSN, having an ITIN ensures you can file taxes legally and participate in other financial or credit-building matters.
In short
ITIN is an alternative for foreigners who cannot get an SSN or those without legal status yet. With it, you can file taxes in the US, open a bank account, or build part of your credit history. If you are eligible, it is best to apply early, as it makes handling taxes and finances much easier later on.
Hi, I'm C from Taiwan, and I'm currently running a business in Los Angeles, USA. When I first arrived, it really wasn't easy. Whether it was the language or cultural differences, I spent a lot of time figuring out every little detail. But all those mistakes I made along the way helped me master the rhythm of adapting to life here quickly. I've gathered all my experience over the past few years on this website, hoping to help fellow Chinese speakers settle into American life sooner. Here, I share how to move over, find a job, and handle various daily tasks, saving you plenty of time and helping you avoid unnecessary detours. I hope my experience helps you start your new life in the US smoothly!
