How to Dissolve an LLC or Corporation in Washington: $0 SOS Fee and the DOR, ESD and L&I Closing Steps

Closing a Washington LLC or corporation looks simple on paper. The Secretary of State (SOS) dissolution filing carries no filing fee, and you file it online through the Corporations and Charities Filing System (CCFS). The hard part is everything around that filing. The state keeps your tax, payroll and workers’ compensation accounts open until you close them, and those accounts generate final reports, final returns and deadlines that the SOS filing does not handle for you.

This guide walks through how to dissolve an LLC in Washington, and how to close a corporation, in the order that tends to avoid problems. It covers the Department of Revenue (DOR), Employment Security Department (ESD) and Department of Labor and Industries (L&I) closing steps. This is informational content, not legal or tax advice. Dissolving an entity can affect contracts, personal liability, loans and tax positions. Talk to a qualified attorney and a CPA before you file.

Dissolve or Simply Stop Operating? Know the Difference

Before you file anything, understand what dissolution does and does not do. A voluntary dissolution ends the entity’s existence. Stopping operations, letting the annual report lapse or waiting for the state to close the entity administratively does not end your obligations. Administrative dissolution is not a substitute for a proper closing because tax and contract obligations remain.

Understand the one-way door too. The SOS dissolution is not reversible after 120 days from its effective date. Once voluntary closure is complete, the Unified Business Identifier (UBI) and the filing history cannot be reactivated. If you might want the name, number or history later, do not close the entity yet.

What You Need Before You Start

• Your 9-digit UBI number, issued by the Business Licensing Service (BLS) inside DOR.
• Your CCFS login and the exact legal name of the entity as it appears on record.
• Your operating agreement (LLC) or bylaws (corporation). These set the vote threshold and the approval you need to dissolve.
• Login information for your DOR, ESD and L&I accounts, plus your L&I workers’ compensation account number.
• Your workers’ compensation policy details and premium payment history.
• A list of every license and permit you hold, and the agency that issued each one.
• A list of assets, including inventory on hand, and a list of creditors and the amounts owed.
• Final bank statements and a plan to pay debts before any money goes to owners.
• Your registered agent’s contact details. Washington requires every business to keep a registered agent with a physical street address in the state.

Step 1: Confirm Your Entity Type and Approvals

Start with the governing documents. An LLC’s operating agreement usually spells out how members vote to dissolve. A corporation’s bylaws and board resolution do the same job. Get the approval in writing, make sure it covers dissolution, and name the person who will sign the SOS filing. Keep the signed approval with your records.

Your entity type also decides whether you have one major extra step. Corporations, both profit and nonprofit, must obtain a Revenue Clearance Certificate from DOR before voluntary dissolution. LLCs do not need this certificate under the rules covered here. If you have a corporation, request the clearance first, because you cannot complete the voluntary dissolution without it. Check the current request process on the DOR website at dor.wa.gov.

Step 2: Wind Up Your Affairs and Notify Regulators

Winding up means finishing current work, collecting receivables, paying creditors and deciding what happens to remaining assets. Do this before you distribute anything to owners. Owners who take assets while debts remain unpaid can create personal exposure, so discuss the order of payments with your attorney.

If your business holds a license in a regulated industry, notify the issuing agency and follow its closing process. Washington agencies that license businesses include the Department of Licensing (DOL), Department of Health (DOH), Washington State Department of Agriculture (WSDA), Liquor and Cannabis Board (LCB), Department of Children, Youth, and Families (DCYF), Department of Social and Health Services (DSHS), Utilities and Transportation Commission (UTC) and the Gambling Commission. Check with each agency about its requirements before you close.

Nonprofit corporations and charities need extra care. If you operate in a regulated area such as charitable solicitation, notify the Attorney General’s office at atg.wa.gov. Charitable assets need Attorney General approval of your distribution plan before they are distributed, so get that approval in writing.

Step 3: Close Your DOR Account and File the Final Excise Return

Washington has no corporate income tax and no individual income tax today. Its main business tax is the business and occupation (B&O) tax, a gross receipts tax with more than 50 activity classifications and no deduction for labor, materials or other costs. Many cities also levy a local B&O tax that DOR does not administer. About 54 cities add their own B&O, so your DOR account is only part of the picture.

In your DOR account, work through these items:

1. File the final excise return. It is due by the 25th of the following month. If you close in March, for example, the final return is due April 25.
2. Pay use tax on inventory taken for personal use. If you or an owner keep business inventory, use tax generally applies to it.
3. Close the DOR account and save written confirmation of the closure.
4. Close any trade name (doing business as) registered through the BLS. Trade names are not registered with the SOS or the county, so they will not close through the SOS filing.
5. Check local licenses. Washington has 39 counties and 281 incorporated cities and towns. Confirm with each city or county whether it issued a separate license, endorsement or local B&O account that needs closing.

Keep your DOR records for five years after closing. That covers returns, invoices, payroll records and the inventory list you used for use tax.

Step 4: Close Your ESD Accounts

ESD covers unemployment insurance and Paid Family and Medical Leave (PFML). Even a small business with a few employees has final reporting duties. The ESD closing process has three parts:

• Submit a Business Change Form to report the closure.
• File your final quarterly unemployment tax and wage reports within 10 days of closure.
• File a final PFML report.

The 10-day window is the one people most often miss. It runs from the date you close your business tax account, so plan your final reports ahead of time. Check esd.wa.gov for the current forms and filing methods.

Step 5: Close Your L&I Accounts

L&I handles workers’ compensation insurance and also registers contractors and licenses electrical and plumbing work. Close the following items:

• Cancel your workers’ compensation policy and confirm the cancellation date with L&I.
• Pay all outstanding premiums before you close the account. Do not assume a balance will be forgiven because the business is ending.
• Notify L&I if you are a registered contractor or hold permits through L&I, such as electrical or plumbing permits.

Step 6: File the Dissolution With the Secretary of State

File this last. Once your DOR, ESD, L&I and regulator steps are finished or nearly finished, file the dissolution through CCFS at ccfs.sos.wa.gov. The filing carries no filing fee. Because the UBI and filing history cannot be reactivated after voluntary closure, an early SOS filing can close off options you may still need.

Before you file, check whether an annual report is still owed. The annual report is $70, and it is due by the last day of the month in which the entity was originally formed or registered. It may be filed up to 180 days early. A late filing carries a delinquency fee, for a total of $95. Confirm with the SOS whether an annual report falls due before your dissolution takes effect.

Expedited service is available for an additional $100 per business entity, generally processed within three business days. It is offered online at checkout or by mail with the envelope marked EXPEDITE. The SOS does not publish a standard turnaround for online business filings. Filings are worked in the order received, and expedited orders go into a separate priority queue.

Step 7: Confirm the Closing and Keep Your Records

After the SOS filing, search the entity in the CCFS Business Search and confirm the status has changed. Save copies of the approval resolution, the SOS filing confirmation, DOR closure confirmation, ESD and L&I confirmations, final returns and final bank statements. Store them for five years.

Closing at a Glance

Common Mistakes to Avoid

• Filing with the SOS first. The UBI and filing history cannot be reactivated after voluntary closure, so an early filing can cost you records you still need.
• Assuming administrative dissolution ends your debts. It does not end tax or contract obligations.
• Skipping the corporate Revenue Clearance Certificate. Corporations need it before voluntary dissolution.
• Missing the 10-day ESD window. Final quarterly reports are due within 10 days of closure.
• Missing the final excise return. It is due the 25th of the following month.
• Forgetting use tax on inventory you took home. Personal use of business inventory triggers use tax.
• Canceling the workers’ comp policy with premiums unpaid. Pay the balance first.
• Overlooking city B&O accounts and endorsements. The state closure does not necessarily close local accounts. Confirm with each city and county.
• Ignoring an annual report that falls due before closing. A late filing carries a $95 total.
• Leaving a trade name open. Close any doing business as registration through the BLS.
• Distributing charitable assets without Attorney General approval. Get the approval in writing first.

What to Expect When You Finish

Owners who work through these steps in order should generally find the closing manageable, though the total time depends on how many accounts you hold, whether you need a DOR clearance, and how quickly each agency responds. Plan for variation rather than a fixed timeline. When the process is complete, the entity may show as dissolved in the SOS Business Search, and your agency accounts should show as closed. Keep the confirmations, since they are your proof if an agency or creditor later asks questions.

Some situations are more involved than the steps above. These include businesses with multiple owners, outstanding debts, pending audits, regulated licenses, or charitable assets. For those, consult a qualified attorney and a CPA before you file. Washington’s Small Business Development Center network at wsbdc.org can also point you toward free business advising.
