How do I deliver documentation to an auditor?

You can deliver the documentation to the auditor by regular mail or email. When possible, we recommend submitting all documentation electronically. If preferred, or for amounts of documentation that exceed email capacity, a secure portal is available for uploading the documentation directly to the auditor. You can contact the auditor to request a secure portal. (Answer revised June 24,2024)
