Tax treatment of prediction market gains varies enormously across Latin American jurisdictions. There is no automated reporting from foreign platforms — every Latam user is responsible for self-reporting under their local rules.
Mexico (ISR — Impuesto Sobre la Renta)
Mexican residents pay ISR on global income, including gains from prediction markets. Crypto gains are treated as gains on movable property under SAT guidelines. Caliente.mx winnings are subject to a special lottery/gambling withholding.
Brazil (IRPF)
Brazilian residents pay IRPF (Imposto de Renda Pessoa Física) on prediction market gains. Crypto held on Brazilian exchanges follows the older regime (monthly gains up to BRL 35,000 exempt, then 15%–22.5%), but crypto and assets held on foreign platforms — the relevant case for Polymarket — are taxed under Law 14.754/2023 at a flat 15% with no monthly exemption, assessed annually. Foreign-source capital gains are reported on the annual return (GCAP/DARF), not via Carnê-Leão.
Argentina (Bienes Personales and Ganancias)
Argentine residents face complex reporting: Impuesto a las Ganancias on income, Bienes Personales on wealth, plus inflation-adjustment provisions. Crypto holdings are in scope. In practice, enforcement varies and many Argentines operate in a self-reporting environment.
Colombia (DIAN)
Colombian residents pay personal income tax on global income via DIAN. Crypto gains are taxable as occasional gains (15% since the 2022 tax reform, Ley 2277, up from the earlier 10%) or as ordinary income depending on classification. Coljuegos-licensed gambling has its own withholding regime.
Practical considerations
Across Latam, no foreign prediction market platform issues local tax forms. Users must export trade history, convert to local currency at the official daily rate, and self-report. Record-keeping requirements vary by country (5 years in most jurisdictions).
