As previously communicated by Avalara, to provide customers with the highest levels of security, Avalara will no longer support TLS 1.0 and 1.1 after February 16, 2023. Learn more here.
If Sage Sales Tax stops working after February 16, 2023, please work with your IT team to determine if you are using TLS 1.0 or 1.1. You can refer to TLS Update Transport Layer Security to TLS 1.2 for information on how to ensure you are using the latest TLS 1.2 version and upgrade recommendations. Once you are sure you are running TLS 1.2, please follow Sage Knowledgebase article 118696 for information about how to get Sage Sales Tax to start calculating with Sage 300 again.
If you experience issues or need help with your Sales Tax solution, contact Avalara.
