How to Dissolve an LLC in Washington State (2026 Guide)

Dissolving an LLC in Washington State is one of the cheapest closures in the country: the state charges a $0 filing fee for the Certificate of Dissolution. The catch is the Business & Occupation (B&O) tax account, which you must formally close with the Washington Department of Revenue or the liability keeps accruing.

Is It Really Free to Dissolve a Washington LLC?

Yes. Washington is one of a small handful of states that charges nothing to file a Certificate of Dissolution through the Secretary of State's online Corporations and Charities Filing System (CCFS). Most states charge between $35 and $200 for the same filing, so Washington genuinely stands out here.

Washington charges a $0 state filing fee to dissolve an LLC online through CCFS. Compared to California's $0 dissolution but $800 annual tax, or Delaware's $200 fee, Washington is among the cheapest states to formally close an LLC.

That said, "free" only describes the Secretary of State step. We've helped 15,000+ clients close US businesses, and the real cost in Washington always comes from the tax side: the final B&O return, any unpaid B&O tax, sales tax reconciliation if you made retail sales, and the $60 annual renewal fee that keeps hitting your LLC every year you stay registered. Ignore those and the $0 filing fee becomes meaningless.

What Are the Steps to Dissolve a Washington LLC?

In our experience, Washington dissolutions move faster when you treat the process as two parallel tracks: the Secretary of State track and the Department of Revenue track. Skipping either one leaves your LLC technically alive for tax purposes.

Here is the full sequence we walk clients through:

1. Hold a member vote and document it. Review your operating agreement for the dissolution vote threshold. If the agreement is silent, Washington's default rule requires unanimous member consent. Record the decision in a written resolution and keep it in your company records.
2. Wind up the business. Stop accepting new work, notify clients and vendors, collect outstanding receivables, pay creditors, and distribute any remaining assets to members according to ownership percentages.
3. File your final federal tax return. Check the "final return" box on Form 1065, 1120, or Schedule C depending on how your LLC is taxed. Issue final K-1s to members if applicable.
4. File a final Washington B&O tax return. Log in to My DOR at dor.wa.gov and submit the final excise tax return covering activity through your dissolution date.
5. Close your B&O tax account. Use the "Close Account" option in My DOR. This also closes any sales tax, use tax, or other DOR accounts tied to your UBI.
6. File the Certificate of Dissolution with the Secretary of State. Log in to CCFS at ccfs.sos.wa.gov, select your entity, and file the Certificate of Dissolution. No fee.
7. Cancel licenses, permits, and registered agent service. Close your city business license, any professional licenses, and terminate your registered agent contract so it does not auto-renew.
8. Keep records for at least 7 years. The IRS and Washington DOR can audit closed entities. Keep tax returns, resolutions, and financial records in a safe place.

What Is the Washington B&O Tax and How Do You Close It?

The Business & Occupation tax is Washington's version of a gross receipts tax. Instead of taxing profit like most states, Washington taxes your gross revenue at rates that vary by classification (retailing is 0.471%, service and other activities is 1.5%, wholesaling is 0.484%, and so on). Every active Washington LLC has a B&O account whether it owed tax that year or not.

Washington's Business & Occupation tax is a gross receipts tax, not a profit tax. Rates range from 0.471% for retailing to 1.5% for service businesses. You must file a final B&O return and formally close the account with the Department of Revenue when dissolving.

The most common mistake we see with Washington dissolutions is filing the Certificate of Dissolution with the Secretary of State and assuming the tax account closes automatically. It does not. The DOR treats your Unified Business Identifier (UBI) as its own open file, and if you leave it open, you will keep receiving filing reminders, estimated assessments, and eventually collections notices even after the entity is dissolved on paper.

To close the B&O account properly:

• Log in to My DOR through dor.wa.gov with your SAW (SecureAccess Washington) credentials.
• File the final excise tax return for the period that includes your dissolution date, even if the amount due is zero.
• Pay any outstanding B&O tax, sales tax, or use tax balances.
• Use "Close Account" inside My DOR and enter the effective close date.
• Wait for the DOR confirmation letter. Keep it with your dissolution records.

How Do You File a Certificate of Dissolution in Washington?

Washington calls the dissolution filing a "Certificate of Dissolution," not "Articles of Dissolution" like most states. The form itself is short, and the entire filing happens inside CCFS, the Secretary of State's online portal at ccfs.sos.wa.gov.

You will need:

• Your UBI number (the 9-digit Unified Business Identifier).
• Your CCFS account login linked to the entity.
• The effective date of dissolution (can be the filing date or a future date within 90 days).
• An authorized signer (member or manager).

Washington's Certificate of Dissolution is filed online through the Corporations and Charities Filing System at ccfs.sos.wa.gov. The filing fee is $0, and processing typically takes 1 to 2 weeks. No paper filing is required, and there is no expedited option because the default is already fast.

Once submitted, the Secretary of State reviews the filing and, assuming no issues, updates your entity status to "Dissolved" in the public records. You will receive a stamped confirmation in CCFS, which is the document banks, the IRS, and your state of foreign registration (if any) will ask for as proof.

What Happens to Your Washington Annual Renewal if You Don't Dissolve?

Every Washington LLC owes a $60 annual renewal fee to the Secretary of State, due during the LLC's anniversary month. If you stop operating but never file the Certificate of Dissolution, the $60 keeps coming due every year, and the B&O filing obligations keep running in parallel.

What happens if you ignore it:

• Miss the renewal and the LLC falls into "delinquent" status.
• After roughly 2 years of non-filing, the Secretary of State administratively dissolves the entity. This is not a clean closure. The B&O tax account stays open at DOR.
• Unpaid renewal fees, late penalties, and any unfiled B&O tax returns can be assessed personally against members if the LLC is treated as non-compliant.
• Reinstating an administratively dissolved LLC later costs more than filing a proper dissolution would have.

In our experience, the "just let it die" approach is almost always more expensive than a clean $0 dissolution plus a final B&O return. The Secretary of State side looks resolved from the outside, but the DOR side quietly accumulates problems that show up when you try to open a new business, apply for a loan, or pass an IRS cross-check.

How Long Does Washington LLC Dissolution Take?

Standard processing for a Washington Certificate of Dissolution filed through CCFS is 1 to 2 weeks from submission. Washington does not publish an expedited option for dissolutions because the online default is already quick compared to states that still process paper filings.

Washington Certificate of Dissolution processing takes 1 to 2 weeks when filed online through CCFS. There is no expedited fee option because online filings are the standard path. Closing the B&O tax account through My DOR typically takes an additional 2 to 4 weeks for the confirmation letter.

Realistic end-to-end timeline for a fully closed Washington LLC:

• Week 1: Member vote, wind-up activities, final invoices and collections.
• Week 2: File final B&O return and close DOR account.
• Week 3: File Certificate of Dissolution in CCFS.
• Week 4 to 5: Secretary of State confirmation posts, DOR closure letter arrives.
• Week 6: Cancel registered agent, close business bank account, file any final federal returns.

What Happens After Your Washington LLC Is Dissolved?

Once the Secretary of State marks the entity dissolved and the DOR confirms the B&O account is closed, the LLC no longer owes annual renewals, no longer accrues B&O filing obligations, and no longer appears as "Active" in Washington public records. The UBI number is retired.

A few things you still need to handle:

• Federal obligations. File the final federal return and any final employment tax forms (941, 940, W-2s, 1099s) if you had employees or contractors.
• EIN. The IRS does not cancel EINs, but you can send a letter to the IRS closing the business account associated with the EIN.
• Foreign registrations. If your Washington LLC was registered to do business in any other state, file a withdrawal or cancellation in each of those states separately. Washington dissolution does not cascade.
• Bank accounts and credit lines. Close them. Leaving a business checking account open attached to a dissolved LLC creates fraud and tax reporting headaches.
• Records retention. Keep dissolution paperwork, final tax returns, member resolutions, and financial records for at least 7 years.

Washington's $0 filing fee makes it tempting to DIY, and for a clean LLC with no B&O balance, no employees, and no foreign registrations, that is reasonable. Where clients call us is when the B&O account has unfiled returns, when there is a multi-state footprint, or when the LLC has been sitting dormant long enough that renewal penalties have stacked up. We've helped 15,000+ clients close US businesses cleanly across all 50 states, and Washington is one of the faster ones when the tax side is handled correctly. If you want us to file your Certificate of Dissolution, close your B&O account, and handle any final returns together, start a dissolution at dissolvemyllc.com and we will take it from here.
