Supporting Documentation

Understand the IRS-issued documents Chariot may request to verify your organization during setup.

When your organization is setting up a Chariot Deposit Account, we may request additional IRS documentation to confirm your affiliation and validate your EIN. These documents help us complete the required compliance steps with our banking partner. If Additional Compliance Verification is needed, we’ll reach out and request one of the following documents from the IRS.

📄 What Is an EIN Issuance Letter (CP-575)?

An EIN Issuance Letter (CP-575) is NOT an IRS Determination Letter. Please do not submit an IRS Determination Letter, which typically begins with the phrase "We're pleased to tell you we determined you're exempt from federal income tax under Internal Revenue Code (IRC) Section 501(c)(3)." These letters will not be accepted in place of the CP-575.

The CP-575 is the official notice sent by the IRS when your organization first applied for an Employer Identification Number (EIN). This letter confirms your EIN assignment and is typically mailed shortly after registration.
