Context

SOFIA (Servicio de Orientación e Información Facilitadora Automatizada) is an AI-powered virtual assistant launched by SUNAT, Peru's National Customs and Tax Administration, in June 2018. Based in Lima, it was one of the first AI virtual assistants deployed by a Latin American tax authority at national scale, operating 24/7 via SUNAT's official website on desktop and mobile.

Objectives

SOFIA aims to provide round-the-clock self-service support to taxpayers — covering RUC registration, SOL password management, income tax procedures, VAT obligations, customs import documentation, and coercive debt collection — reducing the need for queries to be escalated to human staff.

Activities

During an initial pilot (February–April 2018), SOFIA answered taxpayer queries via SUNAT's web channels; it was then rolled out as a permanent national service, handling registration, tax, VAT, customs, and debt-collection questions around the clock.

Results

During the pilot phase SOFIA processed more than 1,400 queries per day and resolved approximately 80% of them without human escalation. By July 2022 it had accumulated 424,000 completed conversations, with SUNAT projecting more than 640,000 interactions for the full year.

Conclusions

SOFIA has sustained more than six years of continuous national operation with no announced discontinuation, showing durable institutional commitment, though no independent evaluation of its accuracy or impact has been published.

Implementation
Indicative cost
Medium (€50k–€500k) — No budget figures are disclosed; classified as medium cost, reflecting integration with SUNAT's existing digital channels and backend tax/customs systems rather than new physical infrastructure.
Time to results
Long (> 3 years) — Operating continuously since June 2018 (over six years as of 2024), moving from a short pilot (Feb-Apr 2018) into permanent national service; classified as long.
Staffing & skills
SUNAT (Superintendencia Nacional de Aduanas y de Administración Tributaria) — sole publicly identified operator

Conditions for success

  • 24/7 availability via SUNAT's existing web channels (desktop and mobile)

Common failure modes

  • No public documentation of the assistant's decision logic or error-handling procedures
  • No independent or controlled evaluation of accuracy has been published; all figures come from SUNAT's own reporting
