The Argentine Federal Administration of Public Revenue (AFIP) has released the critical filing and payment calendar for March 2026, signaling a period of intense administrative activity for the nation’s businesses. These deadlines are strictly tied to each taxpayer’s unique identification code (CUIT), a system designed to manage the high volume of submissions expected as the government seeks to stabilize revenue collection.
For those managing Argentina Tax Deadlines, the window is narrow. Employers are required to submit their sworn affidavits (form F. 931) and settle social security contributions between March 9 and March 11. This immediate deadline puts pressure on payroll departments to finalize complex calculations involving social security, health insurance, and labor risk insurance (ART) within the first two weeks of the month.
The second half of March shifts focus toward consumption taxes. Businesses registered for Value Added Tax (VAT) must navigate a filing window ranging from March 18 to March 26. Under the new fiscal transparency regime, companies are increasingly required to provide detailed, itemized invoices, making accurate digital reporting more vital than ever. For multinational firms and local SMEs alike, missing these Argentina Tax Deadlines is not just a logistical hurdle; it carries the risk of significant administrative penalties and interest charges. As Argentina continues to modernize its electronic settlement systems, staying ahead of these CUIT-based requirements is the only way to maintain a clean compliance record.
