My TaxJar reports are expecting my exempt Magento transactions to have been taxed

Magento 1 is no longer supported. New Magento 1 account connections will no longer be supported, please use the Magento 2 integration. Learn more about this here

Update: This has been resolved starting with version 3.0.0 of our plugin.  If you are using an early version, see below:

Regrettably, we do not yet have the ability to pull the product tax codes on your transactions in from the Magento SOAP/XML API. To get around this, you'll need to upgrade to the latest version of our Magento plugin. This will bypass the SOAP/XML API in Magento and when an order is marked as 'complete' or 'closed', your site will automatically push the data to TaxJar for reports and it will immediately become available inside of your TaxJar account for reporting purposes.

To enable this new syncing feature, once the plugin is installed, you'll want to go to System -> Configuration -> Sales -> Tax and enable the transaction sync feature.  Then you'll need to follow these instructions once your data is in TaxJar.
