Overview
- On October 26, voters nationwide will use the Boleta Única de Papel for the first time to renew 127 seats in the Chamber of Deputies and 24 in the Senate.
- Poll workers will hand each voter the official ballot and an indelible pen; voters mark the chosen casillero(s), fold the paper, and deposit it directly in the urn, and they may request a new ballot if they make a mistake before casting.
- Ballot rules differ by district: 16 jurisdictions allow one mark (deputies only) and eight allow two (deputies and senators); multiple marks in a category or adding objects or images can nullify the vote, and photographing in the booth is prohibited, with Salta warning of fines up to ARS 77,000.
- Voting is mandatory for citizens aged 18–70, with fines for unjustified absences and possible listing in the Registry of Infractores that can limit some official procedures; amounts vary by jurisdiction and prior omissions.
- Operational updates include fines of up to ARS 80,000 for designated polling authorities who fail to serve, free public buses in Salta from 08:00 to 18:30, and eligibility for registered permanent-resident foreigners to vote in legislative races.
