Streamlined Sales Tax (SST)
You may be familiar with and/or registered for Streamlined Sales Tax (SST). Despite the benefits of SST, it may have a negative impact on your implementation of AvaTax. If you have situations where a customer may be exempt for some items they purchase and pay tax for others, you should NOT register for SST. For more information on SST, contact your Avalara representative or visit:

If, for example, you have agricultural-exempt customers who purchase farm equipment parts and service, who are primarily exempt but must pay tax for item such as toys and jackets, you should not register for SST. If you are already registered, you can unregister by contacting your designated SST provider.
