Who this affects

Argentine e-invoice issuers using CAEA. Until 1 August the regime is looser, not tighter: no prior adhesion request is needed to use CAEA as a contingency mode, and no new adhesions to CAEA as a primary mode are accepted.

The change

ARCA General Resolution 5852/2026 postponed the entry into force of RG 5782/2025 and RG 5785/2025 (CAEA-as-contingency-only electronic invoicing regime) from 1 June 2026 to 1 August 2026; from 1 June 2026 no prior adhesion request is needed to use CAEA as a contingency mode and no new adhesions to CAEA as a primary mode are accepted.

What changed in detail

ARCA General Resolution 5852/2026 postponed the entry into force of RG 5782/2025 and RG 5785/2025 — the regime that limits the CAEA (Código de Autorización Electrónico Anticipado) to use as a contingency-only mode of electronic invoicing — from 1 June 2026 to 1 August 2026. In the interim, from 1 June 2026 no prior adhesion request is needed to use CAEA as a contingency mode, and no new adhesions to CAEA as a primary mode are accepted.

What it means

The substance of the reform is unchanged — CAEA is being narrowed to a fallback for when the CAE real-time authorisation service is unavailable — but the clock moves to 1 August 2026. Argentine taxpayers who rely on CAEA as a primary issuing mode have two extra months to migrate to CAE, and during the bridge period they can still invoke CAEA contingency without a prior adhesion request.
