[1] On June 23, 2022, Supplementary Law no. 194 was enacted, with immediate effectiveness, which changed the National Tax Code (CTN) and Supplementary Law no. 87/96 (Kandir Law), classifying electric power, among other goods, as essential, prohibiting the establishment of ICMS rates for transactions with these goods at a higher level than for transactions in general, and applying the non-levy of this tax on transmission and distribution services and sectorial charges related to electric power transactions.
