The norm, in detail
Invoicing: voucher regimes are unified and monthly electronic settlement arrives
ARCA GR 5866/2026 (Official Gazette June 29, 2026)
in forceNATIONAL
Market deregulation
RG ARCA 5866/2026 repeals three receipt regimes and adds monthly settlement for banks, insurers, card issuers and private schools.
What changed and who it applies to
What changed
ARCA reorganizes and simplifies the electronic-voucher issuance regime. It amends GR 1.415 and 4.291 (and amendments) and repeals GR 2.668, 2.719 and 5.824 (plus art. 27 of GR 4.291). It introduces the 'Monthly electronic settlement' as an option for certain taxpayers (financial institutions, insurers, credit/debit card issuers, private educational institutions and virtual-asset service providers, PSAV): they may invoice their operations individually or on a monthly basis, keeping the supporting documentation of the underlying operations. It merges specific web services into one general service (e.g., surety insurance). It does not lower the underlying standard: it consolidates and cuts red tape in invoicing operations. verif Jun 29, 2026 ↗
In force
Jul 1, 2026, with a STAGGERED entry into force: that is the date from which the regime applies, and the resolution itself defers some obligations, with exceptions running through March 2027. ⚠️ It is not a single date: anyone adapting their invoicing reads the exceptions calendar, not just this day. verif Jul 1, 2026 ↗
Are you in or out?
Financial institutions, insurers, credit/debit card issuers, private educational institutions and virtual-asset service providers (PSAV), which can now settle their vouchers on a monthly basis instead of operation by operation. It reduces the administrative burden and the number of reporting regimes/web services to maintain. verif Jun 29, 2026 ↗

Our reading
ARCA administrative simplification (R-desregulación): it unifies scattered electronic-voucher regimes and creates the monthly settlement, lowering the compliance cost without reducing the underlying control. It belongs to the family of ARCA administrative prunings that runs through the program (together with GR 5842 and 5845). A cross-cutting impact confined to fiscal-administrative operations. thesis
