Key terms for configuring sales tax in D365 F&O

Understanding sales tax terminology helps clarify configuration options in D365 F&O.

Goods and services tax (GST) is a federal sales tax. In some provinces, the GST is combined with the provincial sales tax to form a single harmonized sales tax (HST).

Provincial sales tax (PST) and retail sales tax (RST) are often used interchangeably.

GST/HST use an invoice-credit method of value-added tax (VAT). For registrants who sell taxable supplies (including zero-rated items), tracking GST/HST on purchases is very important.

Configuring sales tax codes and groups in D365 F&O

In this section, we outline key Microsoft Dynamics F&O sales tax configurations using functionality in the tax module.

This diagram outlines the relationship between the sales tax components:

Follow this navigation path to reach the sales tax authorities: 

Tax > Indirect taxes > Sales tax > Sales tax authorities 

  • The sales tax authorities depend on the type and location of your business. Common sales tax authorities and the sales taxes they administer are:
    • Canada Revenue Agency – GST/HST
    • Manitoba Finance – MB RST
    • British Columbia Ministry of Finance – BC PST
    • Revenu Québec – QST
    • Saskatchewan Ministry of Finance – SK PST
  • When configuring the sales tax authority, add the vendor associated with the authority to remit sales tax through a vendor using standard payment routines.

Follow this navigation path to reach the sales tax settlement periods:

Tax > Indirect taxes > Sales tax > Sales tax settlement periods

Depending on various factors, including tax authority, and amount collectable, the reporting and payment of sales taxes may be monthly, quarterly, or annually. 

Follow this navigation path to reach the ledger posting groups:

Tax > Setup > Sales tax > Ledger posting groups

Define which general ledger accounts (main accounts) are used for tax transactions.

Follow this navigation path to reach the sales tax codes:

Tax > Indirect taxes > Sales tax > Sales tax codes

  • Sales tax values are connected to the sales tax codes.

  • Current values for common sales tax codes include: 
    • GST – 5%
    • British Columbia – PST 7%
    • Manitoba – RST 7%
    • Quebec sales tax – QST 9.975%
    • Saskatchewan – PST 6%
    • New Brunswick – HST 15%
    • Newfoundland and Labrador – HST 15%
    • Ontario – HST 13%
    • Prince Edward Island – HST 15%
    • Nova Scotia – HST 15%

Follow this navigation path to reach the sales tax groups window:

Tax > Indirect taxes > Sales tax > Sales tax groups

Sales tax groups can be added to vendor and customer records. The tax applied to a transaction is determined by the intersection between the sales tax groups and item sales tax groups. See scenario A for an example and further explanation about how sales tax is determined.

Follow this navigation path to reach the item sales tax groups:

Tax > Indirect taxes > Sales tax > Item sales tax groups

Item sales tax groups default from the items. It is common to have a group that includes all sales tax codes, an exempt group, and various combinations based on the requirements of the business. The tax applied to a transaction is related to the intersection between the sales tax groups and item sales tax groups. See scenario A for an example and further explanation about how sales tax is determined.

Three scenarios of Dynamics 365 sales tax implementation

We’ve mapped out three real-world scenarios to show D365 F&O sales tax configurations in action. These step-by-step examples will help you understand the practical application of the configurations and how they can benefit your business.

Scenario A

Application of sales tax on a customer invoice

An accounts receivable clerk at a manufacturer is creating a $200 free text invoice for a customer. A free text invoice is a customer invoicing method in D365 F&O where no item numbers are specified. The sales tax group on the customer record has 7% Manitoba RST and 5% GST. The clerk enters the item sales tax group of ‘ALL’, which includes all the sales tax codes mentioned earlier in the sales tax codes section.

Tip: If defaulting the sales tax group from the customer isn’t specific enough, the sales tax group can be changed manually when entering the invoice. Reach out to discuss other configuration options that fit your needs.

The intersection between the sales tax and item sales tax groups determines what tax is applied in D365. You can think of this in the form of a Venn diagram:

Before posting, the clerk can see the sales tax calculations by selecting ‘Sales tax transactions’ from the action pane.

A screenshot of a table in Microsoft Dynamics 365 F&O depicting that the customer balance is calculated by adding the total and calculated sales tax.

After posting from the action pane, the clerk selects ‘View accounting’, which shows them that the customer balance is the total plus the calculated sales tax. The GST of $10 and Manitoba RST of $14 are posted to the ledger accounts configured in the ledger posting groups defined on the sales tax codes.

Scenario B

GST receivable (input tax credits)

An accounts receivable clerk at a manufacturer that tracks GST for ITC purposes enters a vendor invoice for a $100 item. With 5% GST, the invoice total is $105.

Configuration note: In the ‘General ledger parameters’ window, the field ‘Apply sales tax taxation rules’ changes the fields available in the ‘Ledger posting groups’ window.

Screenshots of the ‘General ledger parameters’ and ‘Ledger posting groups’ windows. ‘Yes’ is selected for the ‘Apply sales tax taxation rules’ field.

For this scenario, the field is set to ‘No’ and the sales tax receivable is configured for GST.

Screenshots of the ‘General ledger parameters’ and ‘Ledger posting groups’ windows. ‘No’ is selected for the ‘Apply sales tax taxation rules’ field, showing that this option changes the fields available in the ‘Ledger posting groups’ window.

The result is that the $5 GST goes to the GST receivable account.

A screenshot of the ‘My view’ window depicting that if ‘No’ is selected in the ‘Apply sales tax taxation rules’ field, then the GST entered in the ‘Sales tax receivable’ field in the ‘Ledger posting groups’ window is configured for GST.

Scenario C

Per-unit tax

If you need to charge a per-unit tax—for example, a fuel tax of 10 cents per litre—a sales tax code can be configured using the following fields. Adding this code to sales tax groups and item sales tax groups based on the client’s specific needs will allow for the per-unit calculations.

A screenshot of the ‘Sales tax codes’ window with a red box outlining the ‘Amount per unit’ and ‘Unit’ fields, showing that any per-unit tax will be reflected in the ‘Values’ column in the ‘Sales tax code values’ window.
