Removes provisions for acceptance of mail-in ballots received after election day; increases penalties for violation of ballot messenger and bearer limits and candidate prohibition.

New Jersey's A4846 bill changes mail-in ballot rules by requiring all ballots to be received by county election offices by the time polls close on election day, removing current allowances for ballots received up to 144 hours after polls close (if postmarked by election day) or within 48 hours without a postmark. It also increases penalties for violating ballot messenger and bearer rules: currently a third-degree crime, these violations become a second-degree crime, with the same disenfranchisement penalty for convicted individuals. This directly affects voters who mail ballots, individuals acting as ballot messengers or bearers (who must not serve more than three voters per election), and candidates prohibited from serving in these roles. The bill takes effect immediately upon enactment.
