In Spain, IRPF (Impuesto sobre la Renta de las Personas Físicas) withholding may apply to certain sales documents. This operation returns the organization’s configured withholding rate, including its identifier, label, and percentage used when calculating withholding amounts on sales invoices and related documents.
This setup is used together with useWithholdingForSales at organization level and the IRPF-related fields on sales documents, document lines, and products.
