In Brazil, certain demographics—including citizens aged 16 to 17, those over 70, and illiterate individuals—possess the right to vote optionally rather than under the constitutional mandate required for most citizens. For literate citizens between 18 and 70, voting is mandatory. Failure to vote or provide a valid justification, such as health issues or travel, requires a fine of 3.51 reais. Unresolved absences can lead to administrative restrictions, including the inability to obtain a passport, hold public office, or participate in civil service exams.

Recent research by the Avaaz platform and Datafolha, titled ‘Termômetro do Bem Viver’, suggests that voter abstention is being driven by broader social and psychological factors, linking low turnout to an ‘epidemic of loneliness’ and mental exhaustion. Approximately 30 million voters—nearly one-third of the electorate—have failed to participate in recent elections.

During the first round of the 2026 general elections, the Superior Electoral Court (TSE) recorded a national abstention rate of 21.08%, the highest level since 1998. Regarding the Brazilian diaspora, the TSE reported record-high abstention during this first round, with approximately 62.69% of eligible voters living abroad failing to cast a ballot. The largest concentrations of non-voters were identified in Lisbon, Boston, and New York. Analysts have suggested that logistical confusion regarding polling locations and digital information access may have contributed to voters leaving polling stations without casting ballots.

Voters who failed to participate in the first round have until December 3 to justify their absence via the e-Título app or official forms to avoid fines and potential cancellation of voter registration.
