Each time the transaction is saved from or to a status of New, the tax line will be recalculated.
When a transaction with taxes is posted, each tax detail's posting account will be credited if the tax amount is positive or will be debited if the tax amount is negative. Therefore, if a transaction is saved from a status of 'Approved' to 'Ready to Post', the taxes will NOT be recalculated.
Note: Because Customer and Employee Sales share the same initial transaction record view, if the preference to 'Enable Sales Tax' is set to 'No' for either of these transactions, the Tax Class header field will be disabled on the New Sale window until the transaction is saved and it can be determined whether the transaction is a Customer or Employee Sale and has sales tax enabled.
