# Do More with VAT Calculation Method for Taxation

B2C Commerce now supports tax calculation and rounding based on tax groups. You can now calculate tax and use rounding based on tax groups. The calculation method uses a new Tax Rounding Level site preference called Group. The tax groups are exposed via OCAPI and Script API to support customization.

The update includes:

- A new tax rounding level site preference called Group.
- The tax groups are exposed via OCAPI and Script API to support customization.
- If an order was created with price rounding `Policy = Group`, the grouped taxation shows on the Business Manager order details page.

How: To enable rounding per grouped tax rate, in Business Manager Site Preferences, set the Order Item Price Rounding Policy to GROUP.

To ensure a tax rate of zero for promotion line items, in Business Manager select **Merchant Tools** | **Site Preferences** | **Pricing and Promotions** and set the Discount Taxation to Tax Products and Shipping Only Based on Adjusted Price.
