THE VERIFIED BREAKDOWN

  • Taxpayers who received a filing extension and plan to mail their return can generally meet the Oct. 15 deadline as long as the postmark is applied on or by that date.
  • Thirty-five states require mailed absentee ballots to be received by election officials on or before Election Day, according to the National Conference of State Legislatures.
  • In California, mail-in ballots postmarked by Election Day can arrive as many as seven days afterward and still be counted, while Colorado requires receipt by 7 p.m. on Election Day.
