ARCA: CUIT e inscripción en impuestos
Inscripción de personas humanas en Argentina: CUIT, clave fiscal, domicilio fiscal electrónico y alta de impuestos.
CUIT, clave fiscal y domicilio fiscal electrónico
Para inscribirse ante ARCA, una persona humana necesita obtener CUIT y clave fiscal y habilitar su domicilio fiscal electrónico. Tener CUIT no demuestra por sí solo el alta en un impuesto ni el cumplimiento de las obligaciones.
Alta en impuestos y regímenes
El alta se realiza con clave fiscal en Sistema Registral, desde Registro Tributario o Registro Único Tributario, según corresponda. En Alta de impuestos se eligen impuesto o régimen y mes y año de inicio. Al confirmar, el sistema permite consultar e imprimir el formulario 420/T.
Antes de orientar un alta hay que conocer la actividad, el tipo de persona, el régimen y el período. El nombre comercial o los datos guardados en Bigu no acreditan la situación registral ante ARCA.
