Hello Eric,

We don't provide technical support on Sales Taxes on the Forum due to the numerous ways a company may choose to implement item and customer tax statuses, and the regional differences in tax rules.

However, the normal method of dealing with sales taxes that need to be split multiple ways is to send the combined amount across to Ledger and then generate a reallocation batch there to separate the figures.

Your Adagio Consultant should be able to assist you with this.
