The Brazilian Supreme Federal Court (STF) has postponed a key judgment on the Funrural rural social contribution tax, delaying a decision on the tax liability for buyers of agricultural production and maintaining a legal uncertainty estimated to be worth R$20.9 billion for public accounts and the **Brazil agribusiness** sector. The judgment on *sub-rogação*—the mechanism that assigns tax collection responsibility to the buyer, such as frigoríficos (meatpackers) and cooperatives—was expected this week but is now likely to be rescheduled for the near future, according to court sources. The continued delay keeps a massive, uncapped tax liability hanging over some of **Brazil’s largest publicly traded companies**, including food giants JBS (JBSS3), Marfrig (MRFG3), and Minerva (BEEF3), as well as other major buyers of rural output like Suzano (SUZB3).
