How to File a Washington LLC Certificate of Dissolution

To close your Washington LLC, you file a Washington LLC Certificate of Dissolution with the Secretary of State, and there is no filing fee.¹ The certificate is one document in a longer shutdown that also includes authorizing the dissolution internally, notifying creditors, settling debts, and closing your state and federal tax accounts. Skip any of those pieces and you can stay personally exposed to tax bills or creditor claims long after you think the business is done.

Authorize the Dissolution First

Before anything gets filed, the members have to approve closing the LLC. Your operating agreement is the first place to look, since it usually sets the required vote. If the agreement says nothing on the point, Washington law requires written consent from all members.²

Write the decision down. The Secretary of State’s form asks you to confirm the dissolution was properly authorized, and a signed record of the vote or consent protects you if a member later disputes it. For a single-member LLC, a short written resolution with the date is enough.

Filing the Certificate With the Secretary of State

You can file the Certificate of Dissolution online or by mail using the state’s official form.³ Standard filing is free. Expedited service adds $100 and is generally processed within three business days.¹ Online filings tend to move faster than mailed ones even without the expedite fee.

The form asks for your LLC’s registered name, the effective date of dissolution, and confirmation that the dissolution was authorized under your operating agreement or state law. If you’ve already distributed assets, you indicate that on the form as well.

Filing the certificate puts the world on notice that the LLC is dissolved and starts the clock on certain creditor deadlines. It does not, by itself, close the business. The next steps below are where the real protection comes from.

Notify Creditors and Settle Debts

This is the step most owners underdo, and it is the one most likely to come back later. Under RCW 25.15.301, once you’ve filed your certificate, you can send written notice to every known creditor that permanently bars any claim they fail to submit on time. The notice has to describe what information the creditor must include, give a mailing address for claims, and set a deadline at least 120 days out from when the creditor receives it. Any known claim not submitted by the deadline is barred.⁴

If a claim comes in on time and you reject it, the creditor has 90 days after receiving your rejection to sue. Miss that window and their claim is also barred.⁴ The procedure only works for creditors you actually know about, so go through the records carefully: outstanding loans, vendor invoices, lease obligations, and any pending disputes all belong on the list.

Secured debts need to be handled directly. Check for UCC filings against the LLC and confirm whether any tax or judgment liens remain. Members who personally guaranteed loans or leases stay on the hook regardless of what happens to the LLC.

Close Your Washington Tax Accounts

Washington requires a business that quits operating to file a final tax return and pay any outstanding taxes within ten days.⁵ Close your account with the Department of Revenue online or by mail.⁶ If your LLC collected sales tax or owed business and occupation tax, file a final combined excise tax return covering any period not yet reported.

Take the ten-day rule seriously. If you sell or dispose of the business and don’t pay the tax within ten days, anyone who acquires the business or its assets can become personally liable for the full amount owed.⁵ The Department of Revenue can issue a tax clearance letter confirming no state taxes remain due, and it is worth requesting for your own records.

Had employees? File final reports with the Employment Security Department for unemployment insurance and with the Department of Labor and Industries for workers’ compensation. Any city or local business license endorsements attached to your state Master Business License have to be closed separately, or renewal obligations will keep running.

Close Out Federal Taxes

What you file with the IRS depends on how the LLC was classified for federal tax purposes. A multi-member LLC taxed as a partnership files a final Form 1065 with the “final return” box checked at the top and the “final K-1” box checked on each member’s Schedule K-1. A single-member LLC reports its final activity on Schedule C of the owner’s individual return. An LLC that elected S corporation status files a final Form 1120-S with the same “final return” and “final K-1” boxes checked.⁷

An LLC that elected C corporation status has an added step: file Form 966, Corporate Dissolution or Liquidation, along with the final Form 1120.⁷ Report any capital gains or losses from liquidating assets on the appropriate Schedule D.

If you had employees, keep employment tax records for at least four years after the tax becomes due or is paid, whichever is later.⁸ Final W-2s still have to go to employees and the Social Security Administration by the standard deadline; for tax year 2026, that date is February 1, 2027.

Deactivating Your EIN

The IRS won’t cancel an Employer Identification Number, because once assigned it belongs permanently to that entity. You can, however, ask the IRS to deactivate it and close the associated tax account. Send a letter that includes the LLC’s EIN, legal name, address, the EIN assignment notice if you still have it, and the reason for closing the account. Mail it to Internal Revenue Service, MS 6055, Kansas City, MO 64108, or Internal Revenue Service, MS 6273, Ogden, UT 84201. All outstanding returns must be filed and all taxes paid before the IRS will process the deactivation.⁹

Wind Up and Distribute What’s Left

A dissolved LLC doesn’t disappear the day you file. Washington keeps it alive in a limited form for the purpose of winding up its affairs.² During wind-up the LLC can collect debts owed to it, sell property, defend or pursue lawsuits, and settle disputes. It cannot start new business or take on new contracts unrelated to closing down.

The statute requires the LLC to discharge its liabilities before distributing anything to members.² Creditors and tax obligations come first, and only what remains goes to members according to their ownership interests or the distribution rules in the operating agreement. Distributing to members while debts are still outstanding is one of the fastest ways to create personal liability for everyone involved.

If the LLC can’t cover everything it owes, you can try to negotiate settlements with creditors, who often prefer a reduced payment to the cost of litigation. Members who personally guaranteed obligations still owe whatever the LLC can’t pay.

How Long to Keep Records

Record-keeping doesn’t end when the business does. The Department of Revenue requires businesses to keep complete and adequate records for at least five years.¹⁰ The IRS has its own schedule: three years for most income tax returns, seven years if you claimed a deduction for bad debt or worthless securities, and indefinitely if a return was never filed.⁸ Holding all tax records for at least seven years covers the longest standard IRS lookback.

Keep contracts, leases, and settlement agreements at least through their statute of limitations. In Washington, claims on a written contract run for six years.¹¹ Store the records somewhere accessible and make sure at least one former member knows where they are.

If Your LLC Was Already Dissolved by the State

The voluntary process above assumes your LLC is in good standing. If the Secretary of State has already administratively dissolved it for missed annual reports or a lapsed registered agent, filing a voluntary Certificate of Dissolution won’t work; you have to reinstate the LLC first by curing what caused the administrative dissolution, and then wind it up properly.¹² A separate judicial path exists when members are in serious dispute, but that runs through superior court rather than the Secretary of State.¹³
