If this option is selected, the sales tax direction for the selected journal line is controlled by the setup of the Sales tax direction field in the Main accounts - chart of accounts: %1 page for the ledger account that is selected in the Account field on the journal line. If customer payments are recorded on a voucher together with a fee from the bank, the sales tax direction on the sales tax posting of the fee is outgoing (Sales tax payable). This is because a customer account is part of the voucher posting. However, if the Sales tax direction field is selected on the line with the fee, the sales tax direction is instead taken from the main account. The sales tax direction changes to Sales tax receivable if the sales tax direction on the main account is set to Purchase. To view the sales tax direction for the journal line, click Sales tax.
