Guatemala's SAT mandates shift to Virtual Agency for tax declarations

Guatemala's tax authority, the Superintendencia de Administración Tributaria (SAT), is mandating a shift to its Virtual Agency (AV) platform for tax declarations. Beginning June 2, 2026, special taxpayers, regardless of their classification, must use the AV to submit their returns. Consequently, the traditional Declaraguate system will cease to be an option for these forms. This change will extend to general VAT taxpayers starting September 1, 2026, impacting declarations for the monthly period of May 2026 and subsequent periods.

The Virtual Agency promises some streamlining benefits. It will automatically pre-fill taxpayer information, including NIT, name, declaration period, and tax credits for VAT. However, a significant new feature is the introduction of 'suggested declarations,' also known as proformas or shadow declarations. For VAT, SAT will propose amounts for sales and services rendered, along with the corresponding tax liability. By 2027, the system is expected to incorporate purchase information, enabling automatic preliminary tax assessments or credit balance calculations.

Despite these automated suggestions, SAT emphasizes that these declarations are not binding. Taxpayers retain the right to submit different figures, provided they have legitimate legal grounds and adequate documentation. Reasons for discrepancies can include the flexibility to register purchase invoices within two months of issuance, or specific tax-exempt operations like donations or capital contributions. Taxpayers must meticulously document any differences, maintaining these records as part of their internal fiscal control to address potential future inquiries from SAT.
