Concept Definition
What is a discount on an invoice?
A discount on an invoice is a reduction in the invoice amount, applied either at line item level (trade discount) or at invoice level. Discounts reduce the taxable base before VAT is calculated. Early payment discounts (prompt payment discounts) may be conditional and are handled differently depending on the jurisdiction.
How are discounts expressed in UBL?
UBL 2.1 uses AllowanceCharge elements for both discounts (allowances) and surcharges (charges):
- ChargeIndicator: false = allowance (discount), true = charge (surcharge).
- Amount: Monetary discount amount.
- BaseAmount: The base from which the percentage discount is calculated.
- MultiplierFactorNumeric: Percentage discount rate.
- AllowanceChargeReason: Text description of the discount reason.
Frequently Asked Questions
- Does a discount reduce the VAT base?
- Yes. Trade discounts applied before VAT is calculated reduce the taxable amount (net amount). VAT is calculated on the discounted net amount. Early payment discounts are treated differently: VAT may be charged on the full amount or on the discounted amount depending on jurisdiction rules.
- What is the difference between a discount and a credit note?
- A discount is applied on the original invoice to reduce its value. A credit note is issued after an invoice is finalized to reduce the amount already invoiced. Both reduce the buyer's liability, but discounts are on the original invoice while credit notes reference a prior invoice.
