Factura B a consumidor final no identificado

Para emitir una Factura B a un consumidor final sin identificar, omite receiver_tax_id_type y receiver_tax_id_code (o envía receiver_tax_id_type = AR-XXX) y usa receiver_vat_condition_id = 5. El comprobante se informa a ARCA con tipo de documento 99 y número 0.

Según la RG 5700/2025 de ARCA, el consumidor final debe identificarse cuando la operación alcanza ARS 10.000.000, aunque se facture en varios comprobantes. La API rechaza el documento sin receptor identificado cuando su total alcanza ese monto; si la operación completa lo alcanza, informa el receptor aunque cada comprobante sea menor.

Además, si el consumidor final pide la factura para deducir el gasto en el Impuesto a las Ganancias (por ejemplo, gastos médicos), debe identificarse con su CUIT (AR-CUIT), sin importar el monto (RG 5866/2026).
