Tax

A Tax entry defines a specific tax rate used in the system — for example 20% standard VAT, 10% reduced VAT, or 0% for tax-exempt goods. Each Tax belongs to a tax group (TaxGrp) which collects all applicable rates for a given fiscal regime, and the combination of group and rate determines exactly which percentage is applied to a given transaction. Tax entries are referenced on contract positions, shopping cart positions, and invoices to calculate the correct tax amount for each line item.

Tax configuration is a foundational element of fiscal correctness: applying the wrong rate to a commodity or a customer type can result in incorrect VAT filings and legal liability. The system resolves the applicable tax automatically based on the article's tax group assignment and the customer's tax status (private individual vs. registered business), but the underlying Tax master data must accurately reflect the current legal rates for every jurisdiction in which the platform operates. When tax rates change — as they periodically do by legislative action — only the Tax master data needs to be updated, without touching any contract templates or pricing logic.
