01 · Regime

What Convenio Multilateral is

Convenio Multilateral is the framework used to allocate Ingresos Brutos when activity spans more than one Argentine jurisdiction. It is not a Monotributo category.

02 · Signals

When to review multi-jurisdiction activity

Premises, staff, expenses, sales or recurring services outside the main jurisdiction can be signals. No single answer proves an obligation.

03 · Registry

What Padrón Federal does

COMARB describes Registro Único Tributario — Padrón Federal as a shared channel for IIBB registration and data changes.

04 · 2026

All 24 jurisdictions completed the rollout

COMARB says CABA joined the ninth and final stage from 1 August 2026, completing all 24 jurisdictions in Padrón Federal.

05 · Activity codes

NAES is a supporting classification

COMARB publishes the current NAES nomenclator under RG CA 19/2025 and an activity/equivalence annex. A code does not by itself decide territorial treatment.
