# Business Rep/Owner Tax ID requirements for US Companies

This information is required as part of Stripe’s mandatory identity verification requirement: Stripe must collect, verify, and maintain information on the individuals associated with every US Stripe account, as required by our regulators and financial partners. This is intended to promote transparency and prevent individuals from using complex company structures to hide terrorist financing, money laundering, tax evasion, and other financial crimes.

## Tax ID Guidelines
### If the business representative on the Stripe account is a US individual
* We expect you to list your Social Security Number (SSN) as issued by the Social Security Administration and what you would list on your US tax return.
* If you don't have a SSN, please list your Individual Taxpayer Identification Number (ITIN). ITINs are issued by the Internal Revenue Service and are given to those qualifying individuals that are unable to get a SSN.
### If the business representative on the Stripe account is not a US individual
* Without a SSN or ITIN, we expect you to provide your local non-US tax ID and respective documentation to confirm you aren't a US taxpayer. For more information on acceptable documentation, visit our [Stripe Docs](https://docs.stripe.com/acceptable-verification-documents?country=US&document-type=identity).
### Why does Stripe ask for the owner's last 4 digits of SSN/ITIN at $500K of lifetime payment volume for the account?
At onboarding, business representatives provide the last 4 digits of their SSN/ITIN. At $500K of lifetime payment volume:
* All listed owners of the Stripe account must provide the last 4 digits of their SSN/ITIN to confirm we have the correct information on file.
* If we can't programmatically obtain the full nine digit SSN for an owner using information already provided, the user must provide the full nine digits.
