You are using "Plans" in Stripe and expecting tax code "SW054000" to be passed on transaction to the Admin Console but it is not. The tax code shown in the Admin Console is "P0000000".
Ensure you pass TaxCode and ItemCode in Metadata of either 'invoice line item', 'invoice' or 'customer'.
The AvaTax connector for Stripe cannot read 'Plan' metadata.
