Peru: Peru SUNAT Launches Electronic Claims Filing System for Tax Disputes

On 6 October 2026, Peru’s National Superintendency of Customs and Tax Administration (SUNAT) officially launched the Electronic Claims File (Expediente Electrónico de Reclamación – EER), a new digital platform allowing taxpayers to file claims appeals virtually through the SUNAT Operaciones en Línea (SOL) portal. This measure aims to modernize tax dispute resolution, reduce paper-based processing, and accelerate administrative responses. The EER applies to challenges against administrative acts issued by SUNAT, providing a fully digital workflow from submission to notification.

Key Takeaways

  • Fully Digital Claims Process: Taxpayers can now submit reclamation appeals entirely online via the SOL portal, eliminating the need for physical paperwork and in-person visits to SUNAT offices.
  • Streamlined Administrative Review: The electronic file integrates with SUNAT’s internal systems, enabling faster case assignment, tracking, and resolution, with automated notifications at each procedural stage.
  • Legal Validity and Accessibility: The EER has the same legal standing as traditional paper filings, and the platform is accessible 24/7, improving access to justice for taxpayers across Peru.
