I have an invoice from before our company set up AvaTax that I'm trying to credit back. When I generate the credit memo no tax calculates.
- When you generate a credit memo from within an invoice that was already created in NetSuite, it overrides the tax calculation date to be that of the original invoice.
- In AvaTax, check the start date for where you collect in the region listed in the invoice and make sure the start date is before the date on the invoice. If the start date is after, AvaTax doesn't calculate tax on the invoice or the credit memo.
