How do I resolve "Tax Liable filed is Un-checked. Please mark it to calculate tax for this document" in Microsoft Dynamics NAV

Overview

When trying to calculate tax on an invoice it results in the error message, "Tax Liable filed is Un-checked. Please mark it to calculate tax for this document".

Environment

Dynamics NAV

Resolution

  • Sales & Marketing >  Sales > Customers -> Invoicing
  • Check off "tax liable" for Core Services
  • If tax doesn't calculate then the invoice will need to be re-created.
