## Background Argentina's **Resolución General N° 5866/2026**, in effect since **1 July 2026**, changes invoicing obligations for many small and medium-sized entities, especially with respect to electronic invoices (“comprobantes electrónicos”) and identifying buyers in certain transactions.

More taxpayers must issue electronic invoices for qualifying operations. ([biblioteca.afip.gob.ar](https://biblioteca.afip.gob.ar/search/query/norma.aspx?p=t%3ARAG%7Cn%3A5866%7Co%3A9%7Ca%3A2026%7Cf%3A26%2F06%2F2026&utm_source=openai)) - For certain transactions, new **“campos adicionales por RG”** are required: e.g. **Póliza (policy)**, **Endoso (endorsement)**, etc. Buyer or lessee identification may also be required for operations that represent deductible expenses. ([biblioteca.afip.gob.ar](https://biblioteca.afip.gob.ar/search/query/norma.aspx?p=t%3ARAG%7Cn%3A5866%7Co%3A9%7Ca%3A2026%7Cf%3A26%2F06%2F2026&utm_source=openai)) - Non-compliant transactions (e.g. those lacking proper buyer info) may lose deductibility or be disallowed in claims for input credits. For expense recognition and deductions, proper invoice structure is crucial. ## Impacts on Small & Medium Businesses - **Increased compliance burden**: updating invoice‐generation systems to include new fields, training sales staff. - **IT/integration requirement**: using AFIP's electronic systems or sending invoices via authorized providers that support the new data fields. - **Audit risk**: operations without correct invoices or buyer identification may be challenged. ## Opportunity & Strategic Responses - Use the shift to demonstrate professionalism: businesses that comply with full electronic invoicing can attract larger clients who need compliant suppliers. - Implement or upgrade invoicing software in advance, test generation of invoices after **1 July 2026** to ensure compliance. ([biblioteca.afip.gob.ar](https://biblioteca.afip.gob.ar/search/query/norma.aspx?p=t%3ARAG%7Cn%3A5866%7Co%3A9%7Ca%3A2026%7Cf%3A26%2F06%2F2026&utm_source=openai)) - For clients or customers: negotiate that buying entities provide their identification in contracts; this helps avoid friction when companies ask for proper invoice fields. ## Practical Example Suppose you run a café in Buenos Aires and your customer asks for an invoice as a business expense. After 1 July, your invoice must include, for example, the “Póliza” or “Endoso” codes if applicable, especially when the customer expects tax deductibility. If missing, the customer may refuse or AFIP may disallow the expense. ## Conclusion Argentina’s 2026 rule sharpens invoice requirements. Small businesses should respond proactively—update systems, capture client identity appropriately and ensure invoices meet new data field rules. Turn the compliance shift into a business strength.
