Rio Lawmakers Approve ICMS Educacional, Linking City Tax Shares to School Results

Overview

• Rio’s state assembly, which passed the measure Tuesday, created the ICMS Educacional and an index called Ipaerj to redistribute part of the state sales tax to the 92 municipalities based on education outcomes.
• The index will use official data from national exams (Saeb), the School Census, and state assessments to track on-time literacy, learning progress, more creche seats, and growth in full‑time schooling, with no credit for automatic student promotion.
• Implementation will be gradual through 2029, and results from the 2027 evaluations will set how much cities receive in 2030 and 2031 if they meet every condition in the law.
• The delay in passing the rules already cost municipal education budgets about R$117 million in 2026, and lawmakers cited projections of losses reaching roughly R$700 million by 2027 if approval had slipped further.
• The law cleared the chamber after months of debate and 42 amendments reviewed by the Constitution and Justice Committee with technical input from the state Education Secretariat and the Public Ministry, closing a gap that left Rio as Brazil’s last state to regulate a 2020 mandate.
