Overview
- Three news outlets reported on Monday that ARCA has stepped up automated checks that compare declared data with electronic invoices, bank movements, card payments and platform reports to find inconsistencies.
- When ARCA detects mismatches it can issue a recategorización de oficio that takes effect immediately for billing and can raise the monthly amount owed while any appeal is reviewed.
- In serious cases ARCA can exclude a monotributista from the simplified regime and require registration in the general tax system, which brings IVA and Ganancias rules and new formal obligations.
- ARCA notifies decisions through the Domicilio Fiscal Electrónico and taxpayers can submit a digital descargo with bank statements, receipts and other documents but the provisional category remains in force during review.
- One outlet reported the semestral recategorización window will run from July 15 to August 5, 2026, and advisers urge monotributistas to check the Portal Monotributo and gather documentation before and during that period.
