You may have received this email because your Venn USD account is a local U.S.-based chequing account, and Stripe detected a U.S.-domiciled account or individual linked to your profile.
This is a standard process for anyone who connects a U.S. account to Stripe. When you open the form in the email, there will be an option to indicate that you are not a U.S. tax resident — once selected, the form should end there.
If you are a U.S. tax resident, you’ll need to complete the form as instructed.
