The correct configuration is to create sales tax codes, sales tax groups, and item sales tax groups, then assign tax exemption certificates to customers as needed. This setup works because Dynamics 365 Finance uses a three-tier structure: sales tax codes define the actual rate and calculation method, sales tax groups apply to customers or vendors based on their location or status, and item sales tax groups apply to products based on their taxable nature—together they automatically determine the correct tax on invoices. Handling exemptions is then a matter of attaching a tax exemption certificate to a customer record, which overrides the standard group calculation for that customer. On the MB-920 exam, this question tests your understanding of the core tax configuration workflow, often appearing as a scenario where you must distinguish between setting up groups versus individual codes. A common trap is confusing item sales tax groups with sales tax groups; remember that items get one group, customers get another. A useful memory tip: “Codes hold the rate, groups hold the logic, certificates hold the pass.”
