Service Charge Tax Calculation
Introduction
This article provides advanced information about tax calculation on orders that include service charges. See Service Charges and Tips for basic information on service charges.
Important Details
Service charge is calculated on top of tax-inclusive item price for tax-inclusive markets, and on top of tax-exclusive price for tax-exclusive markets.
When the service charge tax type is Apportioned, the base item price is increased by the service charge amount (after tax for tax-inclusive markets, before tax for tax-exclusive markets) in order to inherit the tax of the items in the account proportionally.
The calculation of the total follows the following formula regardless of whether the calculation is for a tax-exclusive or tax-inclusive environment:
Untaxed service charge: Item prices with tax + service charge
Tax-apportioned service charge: Sum of item prices with tax (because item price already includes service charge)
