Form W-7: A Complete Guide to Applying for an ITIN

Many people discover, while preparing their US federal income tax return, that they have no Individual Taxpayer Identification Number (ITIN). Here is how Form W-7 solves that — simply and clearly.

When Do You Need Form W-7?

Filing taxes: individuals who must file a federal income tax return but have no SSN — for example, international students and scholars on F, J, M or Q visas.
Claiming tax benefits: ITIN holders can claim certain tax benefits, such as the foreign tax credit and dependent deductions.
Bank accounts: some financial institutions require an ITIN to open an account.

What Information Is on Form W-7?

Name, mailing address and foreign address
Date and place of birth
Nationality
US visa number (if applicable)
Other details that verify your identity

What Else Do You Need to Provide?

Your passport (required)
A second identity document with an address — for example, a national ID, driver's licence, US visa, or voter registration card.

Can I file Form W-7 online? No. Form W-7 cannot be submitted electronically — it must be sent to the IRS, with original documents in most cases.
