A Washington cannabis processor license lets you process, dry, cure, package, and label usable cannabis, concentrates, and cannabis-infused products for wholesale to other processors and retailers, and you apply for it through the Department of Revenue Business Licensing Service using a Business License Application with the LCB Cannabis Addendum. The privileges, fees, and rules for this license live in WAC 314-55-077, which the state updates each quarter, so always confirm you are reading the most recent version before you file.
Here is the part that surprises most people: the general application window for new cannabis processor licenses is closed right now, so the realistic paths into this license are buying or assuming an existing license, adding a processor endorsement to a producer license, or applying through the Social Equity Program. With nearly 1,400 active processor licenses already in the market and a $250 non-refundable application fee on the line for every filing, a single wrong answer on the addendum can stall your file for months or trigger a denial.
In this guide, you will learn:
- 🌿 What the cannabis processor license is, who must file, and which legal route fits your situation
- 📋 The exact documents and ID numbers to gather before you open the application
- ✍️ A line-by-line walkthrough of the Business License Application and the LCB Cannabis Addendum
- 🧾 Three full filled-out examples using real-world scenarios from start to finish
- ⚠️ The field-level mistakes that cause holds, denials, and wasted $250 fees
What the Cannabis Processor License Is and Who Must File It
A cannabis processor license is the state permit that allows a business to turn raw cannabis into finished products. Under WAC 314-55-077, the holder may process, dry, cure, package, and label usable cannabis, cannabis concentrates, and cannabis-infused products, then sell those products at wholesale to other processors and to retailers. The license does not let you sell to the public, and it does not let you grow plants unless you also hold a producer license.
The agency that issues and oversees this license is the Washington State Liquor and Cannabis Board, often called the WSLCB or just the LCB. The board works hand in hand with the Department of Revenue, which runs the Business Licensing Service that actually receives your paperwork. The Washington State Department of Agriculture also enters the picture if you plan to make edibles, because edibles need a separate endorsement under chapter 15.125 RCW.
You must file for this license if your business will process cannabis for sale at wholesale. That includes companies making concentrates, vape cartridges, pre-rolls, infused gummies, and packaged flower. The statute that authorizes the whole system is RCW 69.50, the Uniform Controlled Substances Act, which gives the board the power to license and regulate the cannabis market.
The deadline that governs you depends on your route. If you are renewing, the annual fee is due before your expiration date, and a late renewal can force you to stop operating. The penalty for skipping the license entirely is severe: processing cannabis without a license is a criminal act under state and federal law, and the board will seize and destroy any product it finds. Each of these pieces connects, because the board cross-checks your application, your funding, and your location against the statute before it ever issues the permit.
Before You Start: Documents and Information You Need
Gathering your paperwork first is the single best way to keep your file moving. The LCB licensing specialist will request many of these items by email through DocuSign after your application reaches the board, so having them ready saves weeks. Below is the pre-filing checklist every applicant should complete before opening the Business License Application.
- Unified Business Identifier (UBI) number. This nine-digit state number ties your business to its tax and licensing records, and without it the addendum cannot link to the right entity.
- Federal Employer Identification Number (EIN). The state and IRS use this to track your business taxes, and a missing EIN delays your tax setup.
- Entity formation documents. Articles of incorporation, LLC certificates, or partnership agreements prove who legally owns and controls the business, and gaps here trigger hidden-ownership reviews.
- True party of interest details for every owner and financier. Under WAC 314-55-035, each person with ownership or a financial stake must be disclosed, and an undisclosed party is grounds for denial.
- Proof of six-month Washington residency. State-issued ID, voter records, or tax records show you meet the residency rule, and weak proof stalls the background phase.
- Source-of-funds records. Bank statements, tax returns, loan papers, and gift letters trace every dollar, and unexplained money is one of the top denial reasons.
- Lease or property documents for the proposed location. A signed lease or deed proves you control a compliant site, because the board will not license a location you cannot use.
- Floor plan and operating plan drafts. Scale drawings of your processing, waste, and camera layout meet WAC 314-55-020 security rules, and a vague plan delays your final inspection.
- Certificate of insurance. Commercial general and product liability coverage of at least $1,000,000 is required under WAC 314-55-082 before any license is issued.
- Personal and criminal history statements with fingerprints. Every true party of interest completes these, and old or incomplete prints reset the background clock.
Collecting these items early matters because the application itself is short, but the documentation phase that follows is where files live or die. If any item is missing when your licensing specialist asks for it, your file sits in a holding pattern until you supply it.
Where to Get the Form and How to Access It
The cannabis processor application is not a single PDF you download and mail by itself. Instead, you start with the Business License Application through the Department of Revenue, then attach the LCB Cannabis Addendum that matches your situation. The board lists every current addendum and form on its Cannabis Forms and Applications page, and the fee figures appear on the License Fee and Description Sheet.
Because the general window is closed, the form you choose depends on your route. The board accepts processor-related filings through the Apply for a Cannabis License page for an Assumption, a Change in Governing People or Percentage, a Change of Location, and Social Equity Program applications. Each of these uses a Business License Application sent to Business Licensing Service with the correct addendum stapled to it.
You can access and submit your filing through three channels. The fastest is the online LCB Portal, which the board now treats as the preferred method for changes to existing licenses. You may also file the Business License Application by mail to the Department of Revenue, or in person at a Business Licensing Service location. Whichever channel you pick, keep a dated copy of everything you send, because that copy is your proof of filing if a document is later lost.
Confirm the revision date printed on each addendum before you file. The board reissues forms when rules change, and the January 1, 2026 compliance updates touched several processor requirements. Filing on an outdated form is a common reason a specialist sends your packet back, costing you days you did not plan to lose.
Step-by-Step: How to Fill Out the Cannabis Processor Application Line by Line
This section is the heart of the article. The walkthrough follows the Business License Application first, then the LCB Cannabis Addendum, field by field. Use the exact box labels printed on the current forms, and italicized text shows you what a real entry looks like.
Business Name and Trade Name (Doing Business As)
This field asks for the legal name of your business and any trade name the public will see. To answer it, write your full legal entity name exactly as it appears on your formation documents, then enter your trade name, or DBA, in the second box. Type both in clear print or all caps so the reader cannot misread a letter.
For example, GREEN SUMMIT PROCESSING LLC goes in the legal name box, and EVERGREEN EXTRACTS goes in the trade name box. A nuance many filers miss is that a sole owner with no formal entity uses their own legal name in the first box. What if you have not registered a trade name yet? You can leave the DBA box blank and add it later through a Change Entity Name request.
A common mistake here is entering the trade name in the legal name box, which breaks the link between your application and your registered entity and forces a correction. A misconception filers carry is that the trade name is the official name; it is not, because the state tracks your business by its legal entity name and UBI number.
Unified Business Identifier (UBI) Number
This field asks for your nine-digit state UBI number. To answer it, copy the number exactly from your existing business registration, with no spaces or dashes added. If you are forming a brand-new entity at the same time, you leave it blank and the state assigns one.
For example, 603 123 456 is entered as 603123456 in the UBI box. A nuance to watch is that an existing producer adding a processor endorsement already has a UBI and must reuse it, not request a new one. What if you operate more than one business? Use only the UBI tied to the entity that will hold this license.
A common mistake is transposing two digits, which routes your file to the wrong account and creates a mismatch the board must untangle. A misconception is that the UBI and the EIN are the same number; they are not, because the UBI is a state identifier and the EIN is federal.
Federal Employer Identification Number (EIN)
This field asks for the nine-digit EIN the IRS assigned to your business. To answer it, enter the number in the standard format with the dash after the first two digits. Confirm it against your IRS confirmation letter so it matches federal records.
For example, 91-1234567 is the correct format for the EIN box. A nuance is that a single-member LLC may use the owner’s Social Security number if it has no EIN, though most cannabis businesses obtain an EIN for banking. What if you applied for an EIN but have not received it? Wait for the IRS confirmation before filing, because a placeholder number causes a tax-setup error.
A common mistake is using a number from a prior, dissolved business, which links your cannabis license to a dead entity. A misconception is that the EIN is optional for small operators; in practice, you need it to open the banking and tax accounts the license requires.
Business Physical Location and Mailing Address
This field asks for the street address of your processing site and a separate mailing address if it differs. To answer it, enter the full physical address, including suite or unit, then the mailing address below. Spell out the city and use the correct ZIP code.
For example, 1420 Industrial Way, Suite B, Spokane, WA 99201 goes in the physical location box. A nuance is that the physical location must be a real, compliant site, not a home, because a processing premises cannot be combined with a residence. What if you use a P.O. Box for mail? You may enter it in the mailing box only, never in the physical location box.
A common mistake is listing a location within 1,000 feet of a school or other restricted entity, which triggers an automatic denial under WAC 314-55-050. A misconception is that you can pick the address later; the board reviews your exact site, so the address must be locked in when you file.
License Type and Endorsement Selection
This field asks which cannabis license and endorsements you are requesting. To answer it, mark the box for Cannabis Processor and check any endorsement you need, such as the cannabis-infused edibles endorsement. Select only what your business model actually requires.
For example, a concentrate maker checks Cannabis Processor alone, while a gummy maker also checks the Cannabis-Infused Edibles endorsement. A nuance is that the edibles endorsement carries extra Department of Agriculture rules under chapter 16-131 WAC, including recipe approval. What if you are a producer adding processing? You select the processor privilege as an addition to your existing producer license.
A common mistake is forgetting the edibles endorsement, which means you cannot legally make ingestible products and must refile later. A misconception is that one processor license covers every product type; it does not, because edibles require the separate agriculture endorsement.
True Party of Interest Disclosure
This field asks you to name every person and entity with ownership or a financial interest in the business. To answer it, list each true party of interest with their full legal name, percentage of ownership, and role, following WAC 314-55-035. Include spouses, because Washington is a community property state.
For example, Maria Delgado, 60% member; James Park, 40% member lists both owners with their stakes. A nuance is that anyone who lends money or shares in profits may count as a financier and must be disclosed even without equity. What if a family member gifted you startup cash? You disclose the gift and provide a gift letter to trace it.
A common mistake is leaving off a silent investor, which the board reads as hidden ownership and treats as a denial reason. A misconception is that only majority owners must be listed; in reality, every interested party, large or small, belongs on this form.
Six-Month Residency Attestation
This field asks each true party of interest to confirm Washington residency for at least six months before applying. To answer it, check the residency box for each person and prepare proof such as a state ID, lease, or tax record. Make sure the dates clearly cover the six-month period.
For example, David Nguyen attests residency and attaches a Washington driver’s license issued more than six months earlier. A nuance is that all true parties of interest must meet the residency rule, not just the lead applicant. What if you recently moved to Washington? You must wait until you reach the six-month mark before you qualify.
A common mistake is submitting an ID dated only a month before filing, which fails the residency test and stalls the file. A misconception is that out-of-state investors can hold an interest; under the residency rule, every interested party must be a qualifying Washington resident.
Source of Funds Statement
This field asks where the money to start and run the business comes from. To answer it, list each funding source, the amount, and supporting records such as bank statements, loan documents, or tax returns. Trace every dollar back to a clean, documented origin.
For example, $150,000 personal savings; $100,000 SBA-style private loan from Cascade Capital LLC shows two clear sources with backup. A nuance is that cash deposits with no paper trail draw extra scrutiny and must be explained. What if a portion is a gift? Provide a signed gift letter naming the giver and the amount.
A common mistake is vague entries like “investor funds,” which the board flags as a questionable source and a denial risk. A misconception is that the board only cares about the total; it actually traces each source, because untraceable money signals possible hidden ownership.
Floor Plan and Operating Plan Attestation
This field asks you to confirm you will submit a compliant floor plan and operating plan. To answer it, check the attestation box and prepare a scale drawing showing your processing area, waste area, cameras, alarms, and controlled-access zones. Use the LCB operating plan form your specialist sends rather than writing your own.
For example, Green Summit Processing attaches a to-scale drawing with a key marking every camera and alarmed door. A nuance is that architectural plans are not required, but the drawing must be to scale and show camera coverage with no blind spots. What if your layout changes after filing? You must submit an updated plan, because the final inspection checks the site against the plan on file.
A common mistake is leaving gaps in camera coverage, which the inspector will fail and require you to fix before licensing. A misconception is that you must hire an architect; you do not, because a clear scale drawing meets the WAC 314-55-020 standard.
Signature, Date, and Attestation Block
This field asks for the signature of an authorized person who certifies that everything in the application is true. To answer it, sign your full legal name, print it below, and enter the date in MM/DD/YYYY format. Only a true party of interest or an authorized officer may sign.
For example, Maria Delgado signs, prints Maria Delgado, and dates it 05/29/2026. A nuance is that an electronic signature through DocuSign is valid when the board sends forms that way. What if more than one owner exists? The form may require each true party of interest to sign their own statements.
A common mistake is leaving the date blank or signing with a nickname, which makes the certification invalid and forces a re-sign. A misconception is that a signature is a formality; in fact, it is a legal attestation, and a false statement is grounds for denial for misrepresentation of fact.

How to File the Completed Form
Once your Business License Application and addendum are complete, you submit them through one of three channels. Pick the channel that fits your route, and keep proof of filing no matter which you choose.
- Online portal. Use the LCB Portal for changes to existing licenses, such as an Assumption or Change in Governing People. The $250 application fee is non-refundable, payment is by card or electronic check in the portal, processing often takes several months, and your proof is the confirmation screen and email.
- By mail. Mail the Business License Application with the addendum to the Department of Revenue Business Licensing Service, P.O. Box 9034, Olympia, WA 98507-9034. Include a check for the fee, expect added mailing and data-entry time, and keep your certified-mail receipt as proof.
- In person. Bring the packet to a Business Licensing Service office. You may pay by card, check, or cash on site, processing still routes through the board, and your stamped copy is your proof of filing.
After Business Licensing Service forwards your file to the LCB, a licensing specialist contacts you for a phone interview and sends the rest of the forms through DocuSign. The annual license fee of $1,381 under WAC 314-55-077 is billed only after Licensing approves your file, and the edibles endorsement adds its own cost. You also pay the approved vendor’s fingerprint evaluation fees separately.
Hold on to every receipt and confirmation. If a document is lost or a fee is questioned, your dated proof of filing is what protects your place in line and your $250 fee.
What Happens After You File
After your application reaches the board, a licensing specialist becomes your guide for the rest of the process. They review your answers, ask about your business, and email you the operating plan, floor plan, personal history statements, fingerprint cards, and financial forms through DocuSign. This documentation phase is usually the longest part, so prompt replies keep your file moving.
Next comes the background and source-of-funds review. The board runs criminal history checks through the Washington State Patrol and the FBI under WAC 314-55-040, and it traces your funding to confirm it is clean. Certain convictions trigger a threshold review, where the board weighs the offense, the time passed, and your evidence of rehabilitation.
Before issuing the license, an Enforcement and Education officer performs a final inspection of your site. They confirm the layout matches your floor plan, the cameras have no blind spots, the surveillance system works, and the premises are secure and separate from any residence. If something fails, they tell you what to fix and return to re-inspect.
Once everything passes, Finance bills your fees, and Customer Service sends an approval letter that acts as a 30-day license until your business license with the cannabis endorsement arrives from the Department of Revenue. If the board denies your application, you may appeal by requesting an administrative hearing in writing, with details on the Board Adjudications page.
Mistakes to Avoid When Filling Out the Form
Each field is its own chance to slip, so watch for these specific errors and what they cost you.
- Entering the trade name in the legal name box breaks the link to your registered entity and forces a correction.
- Transposing UBI digits routes your file to the wrong account and creates a mismatch the board must untangle.
- Using an EIN from a dissolved business links your cannabis license to a dead entity and stalls tax setup.
- Listing a location within 1,000 feet of a school triggers an automatic denial under WAC 314-55-050.
- Skipping the edibles endorsement means you cannot make ingestible products and must refile later.
- Leaving a silent investor off the true party of interest list reads as hidden ownership and can end your application.
- Submitting weak residency proof fails the six-month test and freezes the background phase.
- Writing vague source-of-funds entries like “investor money” flags a questionable source and a denial risk.
- Filing camera-coverage gaps in your floor plan fails the final inspection and delays your license.
- Using an outdated addendum gets your whole packet returned for a re-file.
- Forgetting to sign or date the attestation block voids the certification and forces a re-sign.
- Missing your renewal date can force you to stop operating until you cure the lapse.
Do’s and Don’ts
A few habits separate smooth filings from stalled ones. Each point includes the reason behind it.
Do’s
- Do gather every document on the checklist first, because the documentation phase is where most files slow down.
- Do reuse your existing UBI when adding a processor privilege, since a new number creates a mismatch.
- Do disclose every owner and financier, because hidden ownership is a leading denial reason.
- Do trace each dollar of funding, since the board reviews sources individually, not just the total.
- Do confirm the revision date on each form, because outdated addenda get returned.
- Do keep dated proof of filing, since it protects your fee and your place in line.
Don’ts
- Don’t list a home address as your physical location, because a processing site cannot be a residence.
- Don’t pick a site near a school or restricted entity, since that triggers an automatic denial.
- Don’t leave the edibles endorsement unchecked if you plan to make ingestibles, or you must refile.
- Don’t sign with a nickname, because the attestation must carry your full legal name to be valid.
- Don’t assume the $250 fee is refundable, since every filing fee is non-refundable.
- Don’t ignore your licensing specialist’s emails, because slow replies stretch the timeline for months.
Pros and Cons of Filing on Your Own vs. With Help
Many applicants weigh handling the filing themselves against hiring a cannabis attorney or consultant. The right choice depends on your comfort with detail and the complexity of your funding and ownership.
Pros of filing on your own
- You save thousands in professional fees, which matters when capital is tight.
- You learn the rules firsthand, which helps you stay compliant after licensing.
- You control the timeline directly without waiting on a third party.
- You keep your business details private rather than sharing them broadly.
- You build a direct relationship with your licensing specialist from day one.
Cons of filing on your own
- You carry full risk for errors, and a single mistake can cost the non-refundable $250 fee.
- You may misread true party of interest or source-of-funds rules, which are common denial reasons.
- You spend significant time learning forms a professional already knows.
- You have no advocate if your file heads toward a threshold review or denial.
- You may miss recent rule changes, such as the January 1, 2026 compliance updates.
How the Processor License Compares to the Producer License
Applicants often confuse the processor license with the producer license, but they grant different privileges and sometimes pair together.

|---|---|
| Processes, packages, and labels cannabis products under WAC 314-55-077 | Grows and harvests cannabis plants under WAC 314-55-075 |
| $250 application fee, $1,381 annual fee | $250 application fee, $1,381 annual fee |
| Sells finished products at wholesale to processors and retailers | Sells harvested cannabis to processors |
| Can add an edibles endorsement for ingestible products | No edibles endorsement; growing only |
| Limited to no more than three processor licenses per entity | Limited by canopy tier rather than product type |
FAQs
Is the cannabis processor application window open in Washington right now?
No. The general window for new processor licenses is closed under WAC 314-55-077. You may still enter through assumption, a change in governing people, or the Social Equity Program.
Is the $250 application fee refundable if I am denied?
No. The $250 application fee is non-refundable, even if the board denies your file. You also pay the annual $1,381 fee only after approval.
Do I need a separate endorsement to make edible products?
Yes. Edibles require a cannabis-infused edible endorsement and recipe approval from the Department of Agriculture under chapter 16-131 WAC, in addition to your processor license.

No, not the trade name first. Enter your full legal entity name in the legal name box, and put your trade name, or DBA, in the separate trade name box.
Should I request a new UBI number if I already have a producer license?
No. Reuse your existing nine-digit UBI when adding a processor privilege, because a new number creates a mismatch the board must fix.
Do all owners need to prove six-month Washington residency?
Yes. Every true party of interest must meet the six-month residency rule, not just the lead applicant, and each must provide proof.
Is the EIN the same as the UBI number on the form?
No. The EIN is your federal IRS number, and the UBI is your state identifier. The form has separate boxes for each.
Can I list a P.O. Box as my physical business location?
No. A P.O. Box may go in the mailing address box only. The physical location must be a real, compliant processing site.
Must I disclose a silent investor who has no ownership shares?
Yes. Anyone with a financial interest, including lenders and profit-sharers, is a true party of interest under WAC 314-55-035 and must be disclosed.
Can I file the application online?
Yes. Use the LCB Portal for changes to existing licenses. You may also file by mail or in person through Business Licensing Service.
Will the board check my criminal history?
Yes. The board runs Washington State Patrol and FBI checks under WAC 314-55-040, and some convictions trigger a threshold review before a decision.
Can I appeal if my application is denied?
Yes. You may request an administrative hearing in writing under chapter 34.05 RCW, with details on the Board Adjudications page.
Do I need insurance before the license is issued?
Yes. You must provide a certificate showing at least $1,000,000 in general and product liability coverage under WAC 314-55-082 before issuance.
How many processor licenses can one entity hold?
No more than three. Any entity and its principals are limited to three cannabis processor licenses under WAC 314-55-077.
