Audit enquiries for businesses

  • The Audit enquiries feature allows businesses with an audit case number to submit questions about their audit and get answers electronically using My Business Account.
  • The feature allows businesses to see all their audit-related questions and answers at a glance and to review previous messages using the “View audit enquiry history” function.
  • On average, the Canada Revenue Agency (CRA) will respond to questions within 10 business days.
