How to Start a Seafood or Shellfish Business in Washington: WDFW Fish Dealer $400, Buyer Endorsement $50 and DOH Shellfish Certificates

Learning how to start a seafood business in Washington takes more planning than most food startups because the licensing is split across several agencies. The Washington Department of Fish and Wildlife (WDFW) licenses fish dealers and buyers, the Department of Health (DOH) certifies shellfish operations, and general business paperwork runs through the Secretary of State and the Department of Revenue. Census figures from 2023 count about 400 fishing establishments with employees and 3,398 nonemployer firms in the sector, so the market is active. That tells you the field is real. It does not tell you what you will earn.

Materials and information to gather first

Collect these items before you open any application. Most delays come from missing details, not from the agencies.

• A business name, and a decision on whether you will operate under your full legal name or a trade name
• A Washington registered agent with a physical street address in Washington. PO Boxes and private mailbox addresses are not accepted.
• An email address for the registered agent, which the agent must supply
• Your entity choice, plus the $180 filing fee and the $70 annual report fee if you form an LLC or corporation
• A list of every species you plan to buy, process, sell or harvest, and where each comes from
• Your planned hiring dates, since hiring employees within 90 days affects when you need a state business license
• A budget for WDFW licenses and endorsements, including a $105 application fee for each application
• Contact information for your local health district and your city and county offices
• A business bank account and a system for keeping sales receipts and purchase records

Step 1: Match your activity to the right WDFW license

Washington does not issue one general seafood license. The license you need depends on what you do with the fish, so settle this question first because it drives your costs and timeline. Under RCW 77.65.280, you need a fish dealer license to prepare, process or preserve raw or frozen fish or shellfish, or to wholesale or broker it. Retail businesses that buy only from licensed Washington buyers or limited fish sellers do not need a dealer license.

Your activity	License or endorsement	Published cost
Prepare, process, preserve or wholesale raw or frozen fish or shellfish	WDFW fish dealer license (RCW 77.65.280)	$400 resident or $785 nonresident, plus $105 application fee
Licensed fish dealer taking first possession of fish landed in Washington by commercial fishers, or of raw or frozen fish from interstate or foreign commerce, with one fish buyer	Wholesale fish buyer endorsement (RCW 77.65.340)	$50, plus $105 application fee
Same activities, business operations with two or more employees	Wholesale fish buyer endorsement (RCW 77.65.340)	$245, plus $105 application fee
Commercial fisher selling your own catch at retail	Limited fish seller endorsement (RCW 77.65.510)	$70 resident, plus $105 application fee
Retail store buying only from licensed Washington buyers or limited fish sellers	No dealer license needed	None
Growing, shucking or packing shellfish	DOH shellfish certification (chapter 69.30 RCW)	Check with DOH
Geoduck diving	WDFW diver license and DNR safety program (RCW 77.65.410)	Check with WDFW and DNR

Two points on the table. First, the wholesale buyer endorsement is an addition to the dealer license and applies only to the activities described in RCW 77.65.340, so confirm with WDFW which combination your operation needs. Second, the limited fish seller endorsement is narrow. It lets a commercial fisher sell their own catch at retail without a health-district food permit, but only if the fish is fresh, iced and sold with a receipt. It covers only the fisher's own catch.

Step 2: Choose your entity and file with the right office

Your structure determines whether you file anything with the state before you start. Sole proprietors and general partnerships do not file with the Secretary of State. If you operate that way, your first state filing is the Business License Application in Step 3.

For an LLC, file a Certificate of Formation with Initial Report through the Corporations and Charities Filing System (CCFS) at ccfs.sos.wa.gov. The filing fee is $180. Corporations file Articles of Incorporation with Initial Report for the same $180. Under RCW 23.95.305, an LLC name must include Limited Liability Company, Limited Liability Co., L.L.C. or LLC, and it must be distinguishable from every other business name on record. The name also cannot include bank, banking, banker, trust or cooperative, or certain combinations of building, savings, loan, home, association and society. You can reserve a name for 180 days for $30.

Every LLC or corporation needs a registered agent in Washington under RCW 23.95.405. The agent can be commercial or noncommercial, must consent to serve, must supply an email address, and needs a physical street address in Washington State. There is no fee to change the registered agent or the registered office.

The Secretary of State does not publish a standard turnaround for online filings, and filings are worked in the order received. Expedited service costs $100 per entity and is generally processed within three business days. The fee schedule lists $150 same-day service, but the Corporations Division currently charges $100 for front-counter same-day transactions received before 3:30 p.m. and says it will post 30 days notice before applying the $150 fee. Check the current schedule at sos.wa.gov/corporations-charities before you plan a rush filing.

Step 3: Apply for your state business license through the Business Licensing Service

Washington's general business license is the Business License Application, filed with the Department of Revenue's Business Licensing Service (BLS). It issues your nine-digit Unified Business Identifier (UBI) and handles trade names and state and city endorsements in one application. Corporations, LLCs, LLPs and partnerships must file with the Secretary of State before they submit the BLS application, so Step 2 comes first for those entities.

A state business license is required if any of the following apply: you need city, county or state endorsements; you operate under a name other than your full legal name; you plan to hire employees within 90 days; you sell anything subject to sales tax; your gross income is $12,000 or more per year; you owe any tax or fee to the Department of Revenue; you buy or process specialty wood products; or you meet nexus thresholds. Most seafood businesses meet at least one of these tests, so plan to apply.

The processing fee is $50 to open a business, plus separate endorsement fees. Online applications take about 10 business days, and 2 to 3 weeks longer when city or state endorsements need approval. Mailed applications can take up to six weeks. Apply at dor.wa.gov/open-business/apply-business-license.

If you plan to operate under a name like a brand or a boat name, register it as a trade name. The fee is $5 for each trade name, plus the processing fee: $50 to open or reopen a business, or $10 when the filing is for another purpose, such as adding a trade name to an existing business. Trade names are filed with the Department of Revenue through the BLS, not with the Secretary of State or your county. Details are at dor.wa.gov/manage-business/grow-business/register-trade-names.

Washington has no corporate income tax and no personal income tax on wages. Instead, most businesses pay the state 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. About 54 cities levy their own B&O tax, which the Department of Revenue does not administer, so check your city. The state sales tax rate is 6.5%. Whether a particular seafood sale is taxable depends on what you sell, to whom and in what form. Ask the Department of Revenue before you write sales tax into your price list.

Step 4: Secure city, county and health district approvals

Washington has 39 counties and 281 incorporated cities and towns. Your location controls which city or county endorsements you need and which local B&O rules apply. Request those endorsements through the BLS application in Step 3, and expect extra weeks if approval is required.

Retail food operations generally need a health-district food permit. The limited fish seller exception in Step 1 is the main exception, and it applies only to a commercial fisher selling their own fresh, iced catch with a receipt. Contact your local health district before you sign a lease or buy processing equipment, because its requirements may affect your layout, equipment and sanitation plan. This article does not list health district fees, so confirm them locally.

Step 5: Apply for your WDFW dealer license and endorsements

Start at wdfw.wa.gov and apply for the license and endorsements that match your table in Step 1. Budget for the license fee, the endorsement fee and the $105 application fee for each application. The $400 resident dealer license is the main cost for a processor or wholesaler, and the nonresident fee is $785. Confirm with WDFW whether one application covers the dealer license and endorsements or whether each needs its own, because that changes your total. WDFW's current processing time is not confirmed in this article, so ask the agency directly. Do not buy product for processing until your license is in hand.

Step 6: Certify shellfish operations with DOH and check diving rules

If you grow, shuck or pack shellfish, you need DOH certification under chapter 69.30 RCW. Shellfish is not handled by the Washington State Department of Agriculture (WSDA), so do not start there. Fees for shellfish certification are not confirmed in this article, so check the current fee schedule with DOH at doh.wa.gov. Ask DOH what it reviews before it issues a certificate, what records it expects you to keep, and whether it inspects your facility before you begin operating.

If you dive for geoduck, you need a WDFW geoduck diver license, which is capped at 77 licenses a year, and you must complete the geoduck diver safety program before it is issued (RCW 77.65.410). Check with the Department of Natural Resources at dnr.wa.gov about harvest agreements before you count geoduck revenue in your plan.

Step 7: Register as an employer if you will hire

The BLS application covers your state business license, but hiring requires separate employer accounts. Register with Labor and Industries (L&I) for workers' compensation and with the Employment Security Department (ESD) for unemployment insurance. This article does not list those fees, so confirm current requirements and costs with each agency. Because a plan to hire within 90 days triggers the BLS license, time these registrations with your application.

Step 8: Set up recordkeeping and recurring filings

Build a calendar for every recurring obligation. If you formed an LLC or corporation, the annual report is $70 and is due by the last day of the month in which the business was originally formed or registered, every year. You may file it up to 180 days early. A late filing carries a delinquency fee, for a total of $95. Your B&O returns follow the reporting schedule the Department of Revenue assigns to your account. Keep a sales receipt for every limited fish seller sale and purchase records showing where each species came from. WDFW and DOH may ask to see them.

Common mistakes to avoid

• Filing an LLC and skipping the BLS application. The Secretary of State filing does not replace the state business license.
• Registering a trade name with the Secretary of State or your county. Trade names go through the BLS.
• Using a PO Box or mailbox service as your registered agent address.
• Buying fish from unlicensed sources. Retail buyers should confirm that each supplier holds a Washington buyer license or limited fish seller endorsement.
• Selling your own catch at retail without the limited fish seller endorsement, or selling fish that is not fresh, iced and sold with a receipt.
• Budgeting only for the $400 dealer license. Add the $105 application fee and any endorsement costs.
• Treating shellfish like other food products. Shellfish certification runs through DOH, not WSDA.
• Planning your launch date from the online estimate alone. The 10 business day figure applies to online applications without endorsements.
• Missing the annual report. A late filing costs $95 in total.
• Starting geoduck diving before confirming your WDFW diver license and DNR harvest agreements.

Tips for a faster, cleaner launch

• Work in this order: entity, registered agent, state business license, WDFW licenses, DOH certification, then local health and endorsements. That sequence avoids most rework.
• If timing is tight, pay for Secretary of State expedited service at $100 per entity. Standard filings are worked in the order received.
• Before you pay application fees, have a Washington Small Business Development Center adviser at wsbdc.org check your sequence and your product list.
• Finalize your species list before you apply. Each species and activity can change which endorsement you need.
• For federal small business resources, the SBA's Seattle district office page is at sba.gov/district/seattle.

Expected results

Completing these steps may put you in a position to buy, process, sell or harvest seafood under Washington's license structure. Results depend on your product, your suppliers, your buyers, your location and your operating costs. Licensing does not guarantee sales, profit or a particular launch date. Treat this process as a way to reduce compliance risk and avoid costly rework, not as a promise of any outcome.

Next steps

Start with the activity table in Step 1, then file the entity or business license that applies to you. Confirm each fee and timeline with WDFW, DOH, DNR, the Department of Revenue and your local health district before you sign a lease or buy equipment. For complex ownership, licensing or tax questions, talk to a qualified attorney or CPA.
