A ballot only counts if it gets there on time and filled out correctly. Most rejected ballots fail on simple, fixable mistakes. The voters who fix them in time are the ones who voted early.

1. Good intentions don’t count. Accepted ballots do.

Montana sets aside ballots every election for reasons that have nothing to do with the votes on them:

• Late arrival. Your ballot must be received by 8 pm on Election Day, Tuesday, November 3. A postmark does not count.
• Missing signature, or a signature that doesn’t match the one on file.
• Missing birth year. A 2025 state law added four orange boxes under the signature line on the return envelope. Leave them blank and your ballot gets flagged.

The birth year rule is new, and it is catching people. In Yellowstone County’s spring school election this year, 960 mail ballots were flagged for a missing birth year alone.

2. Vote early and you have time to fix it

When the county flags a problem with your ballot, it isn’t thrown out on the spot. You get a chance to fix it, which election officials call “curing” your ballot. That chance only helps if you have time to use it.

You don’t have to wait for a letter to find out. You can track your ballot online:

1. Go to app.mt.gov/voterinfo (Montana’s voter portal).
2. Look up your record and check your ballot’s status.
3. If there’s a problem, the county also contacts you by mail, and by phone or email if they have them.

Fixing it takes a short form: confirm your identity, sign and date it, add your birth year, and include a copy of acceptable ID. Return it to the election office by mail, fax, email, or in person. The deadline is 8 pm on Election Day. Miss it and your ballot becomes provisional, meaning it is set aside until you finish the fix by 5 pm on Wednesday, November 4.

Return your ballot in mid-October and you have weeks to catch and fix a mistake. Return it on November 2 and you might have hours.

3. Election Day leaves no room for error

Voting at your polling place on November 3 is still a real option. It just has no margin. If your registration has a problem, you’re at the wrong location, or something comes up at work or home, you have one day and one shot.

An early ballot is already in, with time to spare if anything needs fixing.

Two ways to vote early

By mail (absentee). Ballots go out Friday, October 9 to everyone on the absentee list. Fill it out, sign it, add your birth year, and return it. Mail it no later than Tuesday, October 27, or drop it off at the county election office.

In person, early. Go to the county election office at Cedar Hall at MetraPark, get your ballot, vote, and turn it in on the spot. In-person early voting runs through Monday, November 2. Not registered yet? You can register and vote on the same trip. Bring acceptable ID: a Montana driver’s license or state ID, tribal ID, military ID, passport, or Montana University System student ID.

Need a ride?

Volunteers with Northern Plains Resource Council and Yellowstone Valley Citizens Council give rides to the county election office, to vote early or to drop off a ballot. They can also pick up your completed ballot and return it for you. These groups are still organizing volunteers, so let us know you need support and we’ll connect you with a resource!

What’s on the line

Every seat in the Montana House is on this ballot, all 100 of them. The Legislature meets only in odd-numbered years, so the lawmakers we elect in November write Montana’s laws starting in January. County races, judges, and ballot measures sit below them on the same ballot.

Make your plan today

1. Check your registration and track your ballot at app.mt.gov/voterinfo.
2. Pick your method: mail it back by October 27, or vote early in person at Cedar Hall.
3. Pick your day, and make it early.
4. Check the portal a few days after you return your ballot. If it shows a problem, or still isn’t received, call the elections office at 406-256-2740 the same day.
