Washington voters face final deadlines before Aug. 4 primary

Washington’s Aug. 4 primary is four days away, and voters still have limited options to cast a ballot, update registration or correct address information before the 8 p.m. deadline.

The online and mail registration deadline passed July 27. But eligible voters who missed that deadline can still register or update their information in person at a county voting center through 8 p.m. Tuesday, Aug. 4.

Voters with ballots should sign and return them as soon as possible. Ballots may be placed in an official drop box, delivered to a county elections office or voting center, or mailed with an Aug. 4 postmark. The Secretary of State’s voting-by-mail guidance advises voters mailing close to Election Day to be mindful of collection times or use an official ballot drop box.

What deadlines remain

• July 27: Deadline for online and mail voter registration or registration changes. That deadline has passed.
• Aug. 4: Primary Election Day and deadline for in-person registration, address updates and ballot return.
• 8 p.m. Aug. 4: Ballots must be deposited in an official drop box or delivered to a county elections office or voting center by this time.
• Aug. 4 postmark: Mailed ballots must carry an Aug. 4 postmark to be counted under Washington’s ballot-return rules.

The Washington Secretary of State’s 2026 election calendar says registrations or changes made after the online and mail deadline take effect for the next election unless voters complete the process in person before the primary deadline.

How to return a ballot

Official drop boxes are open during the voting period and close at 8 p.m. on Election Day. Ballots may also be hand-delivered to a county elections office or voting center.

Voters who mail a ballot should not assume it must arrive by Aug. 4. The state’s rule is based on the postmark, not the delivery date. Because postal collection and postmark timing can vary, voters mailing near the deadline should consider taking the ballot to a post office for a postmark or using an official drop box instead.

The return envelope must be signed. County election officials review signatures as part of the ballot-processing process and will contact voters if there is a problem with a signature.

Check registration and find an official location

Voters can use VoteWA to verify registration, check whether a ballot has been issued or returned, and review the contests on their ballot. The Secretary of State’s VoteWA voter portal also provides personalized election information.

The Secretary of State’s official drop-box and voting-center locator lists locations across Washington. Voters who need same-day registration or an address update should confirm the location and hours of their county voting center before traveling.

Ballots vary by address. A voter’s ballot may include local offices and measures in addition to state and federal contests, so voters should review the specific ballot shown through VoteWA or in the materials mailed by the county.

What is at stake statewide

The 2026 primary includes 688 races and 1,334 candidates statewide, according to the Washington State Standard’s voter guide, which cited Secretary of State election data.

The ballot includes all 98 seats in the state House, 24 of the 49 state Senate seats and five of the nine Washington Supreme Court positions. The broader primary also includes congressional, county, city and other local contests and measures.

Washington uses a top-two primary rather than a party-nominating primary. All candidates for an office appear on the same primary ballot, and the two candidates receiving the most votes advance to the November general election regardless of party. Two candidates from the same party can advance, or the November contest can include candidates from different parties.

Campaign-finance records are also due

The final primary week includes several campaign-finance disclosure deadlines overseen by the Washington Public Disclosure Commission.

Candidates appearing on the primary ballot and participating political committees had to file seven-day pre-primary C-4 reports on July 28, covering activity from July 14 through July 27. From July 28 through Aug. 3, special reports are due when a candidate or committee receives contributions of $1,500 or more from a single source, or when a political committee makes a contribution of at least $1,500.

Campaign books are open for public inspection from July 25 through Aug. 3. Those records allow residents and reporters to review campaign financial activity during the final days before voting. The filings are disclosure requirements and do not, by themselves, establish wrongdoing.

What happens next

According to the Secretary of State’s 2026 elections calendar, county canvassing boards are scheduled to certify and transmit primary results by Aug. 18. The Secretary of State’s deadline to certify statewide results is Aug. 21.

For voters, the immediate deadlines are simpler: check VoteWA, review the ballot, sign it and return it through an official channel by the Aug. 4 deadline. If registration or address information needs to be changed after July 27, the remaining option is in-person service at a county voting center before 8 p.m. on Election Day.
