The short version.
Washington uses a top-two primary: every candidate for an office runs on the same August ballot regardless of party, and the two with the most votes advance to November. To get on the ballot you file a declaration of candidacy during the state's May filing week and pay a filing fee (or file a petition instead). Washington votes entirely by mail.
This page covers how that works for Walla Walla County. It is not legal advice; for the official rules, your county elections office and the Washington Secretary of State are the sources of truth.

How to get on the ballot in Washington.
The campaigns that win the field are the ones who start building their list of supporters and volunteers before qualifying even opens, not after. The Walla Walla County voter file is already loaded in Motion51, so you can start finding your people now.
Washington has no party primaries. Every candidate for an office appears on the same August ballot (you may state a party preference, but it isn't a party nomination), and the two candidates with the most votes advance to the November general election, even if they prefer the same party.
File your declaration of candidacy.
You file a Declaration of Candidacy during the state's filing week (a set week in May) and pay a filing fee equal to 1% of the office's annual salary (RCW 29A.24.091). If the office pays $1,000 a year or less, there is no fee.
Can't afford the fee? File a petition instead.
In place of the fee, you may submit a filing-fee petition signed by registered voters: one signature for each dollar of the filing fee. So a $500 fee means 500 valid signatures. It's a real option for candidates for whom the fee is a hardship.
You file with your county elections office (the County Auditor, or an elections department like Walla Walla County Auditor — Elections) for county, local, and legislative offices, or with the Washington Secretary of State for federal and statewide offices.
Key Washington dates.
Still open for the November 3, 2026 ballot
Filing week closed on May 8 and the top-two primary was held on August 4, so the ordinary route onto this year's ballot is shut. One route is not: a registered write-in candidacy, and in a low-turnout local race it is a real one.
- Thu Oct 15, 2026 CLOSED. Last day to file a write-in candidacy for the general election WITHOUT paying a filing fee. This is the live 2026 date.
- Tue Nov 3, 2026, 8:00 p.m. STILL OPEN. GENERAL ELECTION. A write-in declaration can be filed right up to 8:00 p.m. on election day (RCW 29A.24.311), but from October 16 the filing fee applies.
- May 4 to May 8, 2026 CLOSED. Filing Week -- CLOSED. Declarations of candidacy were filed with the fee paid or a filing-fee petition submitted.
- Tue Aug 4, 2026 CLOSED. Top-two primary -- HELD.
Two things to know before you plan a write-in campaign. RCW 29A.24.311(3)(a) bars you from filing as a general-election write-in if your name was printed on the primary ballot for that same office, or if you were already a write-in candidate for it at the primary. And registering is not optional: no votes are counted at all for a write-in candidate who has not filed a declaration.

2028 -- computed from statute, not yet published
The Secretary of State has not released a 2028 calendar. The three dates below follow directly from statute, so treat them as the shape of the year and confirm each one before you rely on it.
- Mon May 1 to Fri May 5, 2028 FILING WEEK -- COMPUTED. RCW 29A.24.050 fixes it as the first Monday in May and the following Friday.
- Tue Aug 1, 2028 Top-two primary -- COMPUTED. RCW 29A.04.311 puts the primary on the first Tuesday of the preceding August.
- Tue Nov 7, 2028 GENERAL ELECTION -- COMPUTED. The first Tuesday after the first Monday in November. U.S. Senate and the statewide executive offices return to the ballot this year.
Status as of October 19, 2026: dates that have passed are greyed out and marked CLOSED.
The 2026 and 2027 dates come from the Washington Secretary of State elections calendar (sos.wa.gov/elections/calendar) and were checked on 2026-08-20. The 2028 dates are arithmetic from statute rather than a published calendar. Confirm anything you plan to rely on with your county elections office or the Secretary of State candidate page.

Offices on the ballot.
Up in 2026 (primary August 4, general November 3):
- U.S. House — all 10 Washington seats
- Washington Legislature — all 98 state House seats and about half of the 49 state Senate seats
- County & local — county council or commission, assessor, sheriff, prosecutor, etc. (varies by county)
- Judicial — Supreme Court, Court of Appeals, and Superior Court seats up this cycle
No U.S. Senate or statewide executive offices are on Washington's 2026 ballot; those were on the ballot in 2024 and return in 2028. Note also what is not in the list above: city and town councils, mayors, school boards and the fire, port, water and library districts are elected in ODD years, so their next ballot is November 2, 2027. For the official list of Walla Walla County seats up this cycle, check your county elections office.

After you file: building a field operation.
Filing is the paperwork. What starts then is the actual campaign: reaching voters, recruiting volunteers, and identifying the people who'll return a ballot for you in August and November.
That's what Motion51 is built for. The Walla Walla County voter file is already loaded: no chasing a CSV or paying a vendor. You scope your district, recruit volunteers, cut turf, and start knocking. The app works offline for neighborhoods with bad cell coverage, and every door is logged with a timestamp, a strong complement to Washington's all-mail ballots.
If filing is settled and you're thinking about the field operation, our For Candidates page walks through the next steps.
