Edit Sale -> Sales Types (assigned to customer), and uncheck Tax Included.

I'm setting up a new company (US) on the same accounting server that already has configured other companies (Canadian).   The Canadian company exhibits correct tax behaviour - Under Sales -> Direct Invoice item price is _before_ tax.   On the US company Direct Invoice item price is _after_ tax.   I unable to find where to change this.   The US company should also be configured for before tax item pricing.   How can I change this?
