RITA — Guatemala's AI Tax and Customs Virtual Assistant

Guatemala's national tax and customs authority, the Superintendencia de Administración Tributaria (SAT), launched a virtual assistant called RITA — Respuesta Inteligente Tributaria y Aduanera ("Intelligent Tax and Customs Response") — in April 2019. Built on Google's Dialogflow platform, RITA answers taxpayer questions in colloquial Guatemalan Spanish, including slang terms. It was designed to relieve pressure on SAT's Contact Center, where an estimated 34.94% of incoming calls historically went unanswered. SAT staff have noted that many users do not realize they are conversing with a bot rather than a human agent.

RITA's stated purpose was to relieve pressure on SAT's traditional phone-based Contact Center, where a large share of calls historically went unanswered. It was also intended to provide a channel available continuously, unconstrained by call-center staffing, business hours or queueing, unlike the phone line it complements.

RITA operates continuously, 365 days a year, and is continually updated with new topics identified from real user conversations. It complements, rather than replaces, SAT's traditional Contact Center phone line.

RITA served 335,000 taxpayers between April and December 2019, its first partial year of operation. By the last quarter of 2023 alone, it was handling more than 1.1 million queries, with a reported 92.35% satisfaction rating in user surveys. This represents substantial, sustained growth in usage over multiple years of continuous operation.

Public reporting located for this practice covers usage volume and satisfaction scores but does not document RITA's error rate, its escalation-to-human-agent rate, or a published data-protection policy. As a result, this practice is best supported by evidence of demonstrated adoption and continuity rather than by transparency or governance documentation.
