What is an ITIN?
Who needs an ITIN?
An Individual Taxpayer Identification Number (ITIN) is a 9-digit tax ID issued by the IRS to individuals who do not qualify for a Social Security Number but need to meet US tax obligations — including filing US tax returns, opening US bank accounts, or satisfying IRS withholding requirements.
- Foreign nationals owning a US LLC or Corporation
- Non-residents earning income from US real estate or investments
- Individuals opening a US personal bank account
- Anyone subject to IRS tax withholding requirements
- Spouses and dependents of US visa holders
Our CAA advantage
Why use an IRS Certified Acceptance Agent?
Certified Acceptance Agents are authorized by the IRS to verify identity documents for ITIN applications.
- No passport mailing. We certify your ID documents on our end — you never ship originals internationally.
- Fewer rejections. CAA-submitted W-7 applications have significantly lower rejection rates than self-filed ones.
- Completely done-for-you. We prepare your W-7, gather supporting docs, and submit directly to the IRS on your behalf.
