Tax plugin

Current version: 9.3

The Sitecore.Commerce.Plugin.Tax plugin is a sample tax calculator that implements pipeline blocks and policies to apply tax adjustments both at the cart level and at the line item level.

Note

The Sitecore.Commerce.Plugin.Tax plugin is provided as a sample only and not intended for production. You can use the sample tax plugin as a starting point to develop a custom tax plugin that meets specific tax calculation requirements.

Pipeline blocks

The Sitecore.Commerce.Plugin.Tax plugin defines the following pipeline blocks used to calculate how taxes apply to an order:

  • The CalculateCartLinesTaxBlock pipeline block

  • The CalculateCartTaxBlock pipeline block

  • The RegisteredPluginBlock block

The CalculateCartLinesTaxBlock block

In the ICalculateCartLinesPipeline pipeline, the CalculateCartLinesTaxBlock block is a sample pipeline block that calculates the tax totals applicable at the cart line level. It adds the CartLineLevelAwardedAdjustment to all cart lines that contain taxable sellable items. The tax rate used to calculate this adjustment is configurable in the GlobalTaxPolicy policy.

Note

The CalculateCartLinesTaxBlock block is intended as a sample only. In a typical Commerce deployment, you replace this block with a call out to the appropriate third-party tax provider for your deployment.

The CalculateCartTaxBlock block

In the ICalculateCartPipeline pipeline, the CalculateCartTaxBlock block is a sample pipeline block that calculates cart level tax adjustments that represent the total taxable tax amount applicable to the entire order. The tax rate used to calculate this adjustment is configurable in the GlobalTaxPolicy policy.

Note

When a cart contains a SplitFulfillmentComponent component, the CalculateCartTaxBlock block takes no action, and tax adjustments are calculated at the item level only.

The RegisteredPluginBlock block

In the IRunningPluginsPipeline pipeline, the RegisteredPluginBlock block is used to register the tax plugin with the Commerce Engine.

Policies

The sample Sitecore.Commerce.Plugin.Tax plugin defines tax policies that allow you to configure how the CalculateCartLinesTaxBlock and the CalculateCartTaxBlock blocks apply tax adjustments.

GlobalTaxPolicy policy

You can configure the GlobalTaxPolicy policies in the following default Commerce environment configuration files:

  • PlugIn.Habitat.CommerceAuthoring-1.0.0.json
