Question 280
After resolving this Dynamics 365 Finance case: A tax-exempt customer is charged standard tax because the exemption status was never assigned. What preventive control belongs in the operating procedure?
Explanation
Correct Answer
Require supporting exemption documentation before modifying customer tax setup. This prevents recurrence of the identified mechanism: A tax exemption changes eligibility for specified tax treatment, not the global tax rate for all customers. Validate the control by checking: A qualifying invoice excludes tax while an ordinary customer still incurs tax.
Incorrect Answers
Validate tax group inheritance on each invoice source type. That safeguard is aimed at a different risk: A tax code applies to a customer but a free-text invoice does not inherit the expected item tax group. It does not most directly prevent recurrence of: A tax exemption changes eligibility for specified tax treatment, not the global tax rate for all customers.
Review supplier withholding classification before payment approvals. That safeguard is aimed at a different risk: A vendor invoice should withhold a statutory portion, but its withholding tax group is absent. It does not most directly prevent recurrence of: A tax exemption changes eligibility for specified tax treatment, not the global tax rate for all customers.
Regression-test boundary dates for every statutory tax change. That safeguard is aimed at a different risk: A jurisdiction increases tax from 8% to 9% midyear, but prior invoices must remain at historical rates. It does not most directly prevent recurrence of: A tax exemption changes eligibility for specified tax treatment, not the global tax rate for all customers.
