Mail-in ballots that arrive after Election Day should be rejected even when they were postmarked by the deadline

What's this about?

People disagree about whether mail-in ballots should count when they arrive after Election Day.

The voter may have mailed the ballot on time, but the mail may have moved slowly.

What supporters say

• A receipt deadline gives election staff one clear rule: count only ballots they get by the set date.
• This rule helps staff keep ballots safe and know when they took control of each ballot.

What critics say

• Some states already count ballots with a postmark (a mark showing when the mail was sent).
• Mail delays can hurt voters who sent their ballots before the deadline.

How to read this

The number of points on each side does not show which side is right; strong proof matters more.

The bottom line

We are not sure yet that one rule works best everywhere. Receipt deadlines make ballot work simpler, but they can punish voters for delays they cannot control.

The claim that all mail-in ballots arriving after Election Day should be rejected—even if they were postmarked on time—rests on a trade-off between simple administration and protecting voters from postal delays. The available evidence does not show that one rule is best everywhere.

The case for

A receipt deadline gives election officials a clear legal endpoint: the ballot must be physically in their possession by the cutoff. That can make counting and custody easier to manage, because officials do not need to decide whether a postmark is genuine, readable or timely. They can focus on one question—when did the ballot arrive? 1

This approach also treats mailing and delivery as separate events. Postal guidance warns that delivery times vary, so a postmark does not guarantee that a ballot will arrive quickly. Requiring receipt by a fixed date ensures that officials have custody of the ballot before counting begins, rather than treating proof of mailing as enough. 2

Several states use receipt deadlines, showing that this system is legally workable. But that fact supports feasibility, not necessarily the conclusion that receipt deadlines are fairer or more secure. The strongest argument for rejecting late-arriving ballots is therefore administrative clarity and a straightforward custody rule, not evidence that accepting them creates proven harm.

The case against

An absolute receipt deadline can penalize voters who followed the instructions and mailed their ballots on time. Postal disruptions can delay ballots that were sent before the legal deadline, meaning the voter’s action was timely even though the ballot was not. A peer-reviewed study on postal disruptions provides direct support for this concern. 3

The risk is especially important where the law defines postmarking as the voter’s operative deadline. In that situation, rejecting a ballot because it arrived late shifts the consequences of transportation problems from the postal system to the voter.

State practice also shows that rejecting every late-arriving ballot is not the only workable option. The National Conference of State Legislatures lists jurisdictions that accept some ballots after Election Day when they carry a timely postmark and meet other legal requirements. Those safeguards can include rules about postmarks, verification and custody. 4 This does not prove that postmark-based acceptance is better nationwide, but it weakens the argument that such ballots must be rejected simply because acceptance is impractical.

At the same time, the available evidence does not provide a reliable national count of ballots postmarked by Election Day but received later. It also does not offer a dependable comparison of fraud, security risks, administrative costs or voter exclusion under the two systems. Government surveys collect information about mail-ballot timing and rejection, but they do not isolate the precise group at issue here.

The bottom line

The evidence does not support the categorical claim that all ballots arriving after Election Day should be rejected when they were postmarked on time. But it also does not establish that every jurisdiction should accept them.

The overall policy question is best described as even, with low confidence. The evidence more strongly shows that both receipt-based and postmark-based systems are legally workable than it shows that either is universally superior. Receipt rules offer clearer administration and custody; postmark rules better protect voters from postal delays. Because states differ in their deadlines, verification systems and postal conditions, the choice should depend on carefully written local rules and evidence about how each system affects voter inclusion, administration and election security.
