Known issues
Callers often experience long wait times, particularly during peak hours and near tax deadlines. To avoid delays, try calling early in the morning between 08:30 and 11:00. Some users report difficulties with the speech recognition system, especially if there is background noise or strong accents. Speaking clearly and using simple phrases can help. If problems persist, request to speak directly to an adviser. Additionally, ensure your business tax account details and address are current to pass security verification, as failure to do so may result in call termination.
