2026 Election Dates: Primary, Runoff, and General Election Calendar

Elections in 2026 don't just happen on one day. Between primaries, runoffs, early voting, and mail ballot deadlines, the election season spans most of the year. Here's your complete calendar of critical dates so you don't miss any deadlines.

The Most Important Date: November 3, 2026

Election Day for the 2026 midterm elections is Tuesday, November 3, 2026.

Federal law requires that general elections for Congress occur on "the Tuesday next after the first Monday in November" of even-numbered years. This system, dating back to 1845, was designed to accommodate agricultural schedules and travel times — considerations that no longer apply but the tradition persists.

On November 3, voters will decide:

• All 435 U.S. House seats
• 34 U.S. Senate seats
• 36 gubernatorial races
• Thousands of state and local offices
• Hundreds of ballot measures

But November 3 is just one point in a months-long process. Here's everything else you need to know.

Primary Elections: March through September 2026

Primary elections determine which candidates will represent each party in the general election. Timing varies dramatically by state — some vote as early as March, others wait until September.

Early Primaries (March-May)

March 2026:

• Texas (March 3) — First major primary state, often sets narratives for the rest of the year
• North Carolina, Alabama (March 3)

April 2026:

• Illinois (April 7)
• Wisconsin (April 7)

May 2026:

• Indiana, Ohio (May 5)
• Nebraska, West Virginia (May 12)
• Pennsylvania, Kentucky, Oregon, Idaho (May 19)
• Georgia (May 19) — Major battleground state

Summer Primaries (June-August)

June 2026:

• Montana, New Jersey, New Mexico, South Dakota (June 2)
• Virginia (June 9)

Louisiana and California have unique primary systems (jungle primaries/top-two) where all candidates regardless of party compete, and the top two advance to the general — even if they're from the same party.

Voter Registration Deadlines

Most states require you to register 15-30 days before Election Day, though some offer same-day registration.

States with Same-Day Registration

These states let you register and vote on the same day during early voting or on Election Day:

• Alaska, California (conditional), Colorado, Connecticut, Hawaii, Idaho, Illinois, Iowa, Maine, Maryland, Michigan, Minnesota, Montana, Nevada, New Hampshire, New Mexico, Utah, Vermont, Virginia, Washington, Wisconsin, Wyoming, Washington D.C.

Typical Registration Deadlines (Non-Same-Day States)

• 30 days before Election Day (October 4, 2026) — Arizona, Arkansas, Florida, Georgia, Kentucky, Louisiana, Mississippi, Ohio, South Carolina, Tennessee, Texas
• 25 days before (October 9, 2026) — Alabama
• 21 days before (October 13, 2026) — Indiana, Kansas, Missouri
• 15 days before (October 19, 2026) — Delaware, Massachusetts, Nebraska, New York, North Carolina, Oregon, Pennsylvania, Rhode Island, South Dakota

Check your specific state deadline on our voter registration guide.

Early Voting Periods

Early in-person voting typically begins 2-4 weeks before Election Day, though some states start earlier.

When Early Voting Starts (Approximate)

• 45 days before (September 19) — Minnesota, South Dakota, Virginia, Wyoming
• 29 days before (October 5) — Illinois
• 22-20 days before (October 12-14) — Arizona, Georgia, Nevada, North Carolina, Ohio, Texas
• 15-10 days before (October 19-24) — California, Colorado, Florida, Tennessee, Wisconsin

States like Oregon, Washington, and Colorado conduct elections almost entirely by mail, so "early voting" means the period when ballots are mailed out and can be returned.

Mail-In Ballot Deadlines

If you're voting by mail, you need to:

1. Request your ballot (if your state requires a request)
2. Return it on time

Request Deadlines

Deadlines to request a mail ballot vary:

• 7-11 days before Election Day — Most common (October 23-27)
• 4 days before (October 30) — Some states with more flexible systems

Some states automatically mail ballots to all registered voters (universal vote-by-mail): California, Colorado, Hawaii, Nevada, Oregon, Utah, Vermont, Washington.

Return Deadlines

This is critical: your ballot must be RECEIVED by the deadline, not just postmarked in many states.

• Received by Election Day (Nov 3, 7-8 PM) — Most states
• Postmarked by Election Day, received within 3-10 days after — Some states (California, Illinois, Maryland, Nevada, New York, North Carolina, Ohio, Pennsylvania, Utah, Virginia, Washington)

Best practice: Mail your ballot at least one week before Election Day, or drop it at an official drop box if your state offers them.

See our complete mail-in voting guide for state-specific rules.

Runoff Elections

Some states require runoff elections if no candidate wins a majority in the primary or general election.

States with Runoff Requirements

• Georgia — If no candidate receives 50%+1, the top two advance to a runoff (typically held 4 weeks after the general)
• Louisiana — Uses a "jungle primary" where all candidates compete in November; if no one gets 50%, a runoff occurs in December
• Alabama, Arkansas, Mississippi, North Carolina, South Carolina, Oklahoma, South Dakota, Texas, Vermont — Runoffs for primary elections only (not general)

If Georgia's Senate or gubernatorial races require a runoff, expect a December 1, 2026 runoff election.

Key Dates Summary

Don't Miss Your Deadlines

The single biggest reason eligible voters don't vote is missing a deadline — registration, ballot request, or ballot return.

Here's how to stay on track:

1. Check your registration status now — Many states have online lookup tools
2. Register or update your registration if you've moved or changed your name
3. Mark your calendar with your state's specific deadlines
4. Decide how you'll vote — in person on Election Day, early, or by mail
5. If voting by mail, request your ballot early and return it at least a week before Election Day
6. If voting in person, find your polling location and check hours

Use our ballot lookup tool to see what will be on your ballot and plan your votes ahead of time. Check your state page for specific deadlines and voting rules.

Why Primary Dates Matter

You might wonder why you should care about primary dates if you plan to vote in November. Here's why primaries matter:

• Primaries often determine the winner in safe districts — In heavily Democratic or Republican areas, the primary effectively decides the race
• Lower turnout means your vote counts more — Primary participation is typically 20-30%, so engaged voters have outsized influence
• You shape the choices for November — Don't complain about the general election candidates if you didn't vote in the primary
• Some states allow crossover voting — Open primary states let you vote in either party's primary regardless of your registration

Check whether your state has open or closed primaries, and whether you can participate in both primary and general elections for maximum impact.

Final Thoughts

The 2026 midterm elections span nearly a full year from the first primaries to potential runoffs. Staying informed about deadlines ensures you don't lose your voice due to a missed date.

Key takeaways:

• November 3, 2026 is Election Day for the general election
• Primary dates range from March through September
• Register to vote by your state's deadline (typically October 4-19)
• Early voting begins in most states in mid-October
• Mail ballots must be requested by late October and returned by November 3 (or earlier in many states)

Mark your calendar, make your plan to vote, and participate in every stage of the democratic process.
