How licensing works in Seattle (fast overview)
Start with the state, then the city. Many businesses also need county health permits, plus specialty licenses. You’ll also register for state and local taxes. Here’s the big picture:
Levels of government, who does what, and where to apply
Level | What you get or must do | Where to apply | Fees (examples) | Source |
---|---|---|---|---|
State of Washington (DOR BLS) | Washington State Business License and UBI; add city license endorsements; register for state taxes (sales tax, state B&O, etc.) | Apply or manage at DOR BLS | Processing fee 19∗∗;tradename(DBA)∗∗19**; trade name (DBA) **5; city endorsements vary | DOR fees overview |
City of Seattle (FAS) | City general business license (Business License Tax Certificate); city B&O and payroll expense tax (if applicable) filing | City licensing info hub: Seattle business licenses & taxes; File taxes at FileLocal | Annual city license fee is tiered by gross revenue (varies; verify fee) | Seattle License & Tax Administration |
County (Public Health – Seattle & King County) | Food establishment permits, mobile unit permits, plan review, etc. | Food business permits | Fees vary by operation type and complexity | King County Food Protection |
State specialty regulators | Liquor/cannabis/tobacco/vapor; childcare; professional licenses; contractors | Liquor & Cannabis Board licensing; L&I contractors | Varies by license | See agency links |
City permitting (SDCI/SDOT/SFD) | Zoning checks, building and sign permits, sidewalk/streets use, fire permits | SDCI permits; SDOT permits; Seattle Fire permits | Varies by permit | See agency links |
Reality check: You must apply in the right order. If you’re forming an LLC/corporation, do that first with the Secretary of State, then apply for the state business license (UBI), then add the Seattle city endorsement, then layer on permits.
What to do if this doesn’t work
- Use the state’s free “wizard” to confirm requirements: Washington State Business Licensing Wizard (official).
- Call DOR BLS at 360‑705‑6741 for licensing questions, and the City of Seattle License & Tax team at 206‑684‑8484 for city requirements. See Seattle contact page.
- Book a no‑cost advisor: Washington SBDC or SBA Seattle District Office.
Step 1 — Choose your structure and name (do this first)
- Decide on sole proprietor, partnership, LLC, or corporation. If you choose an LLC/corporation, form it with the Washington Secretary of State (SOS) before you apply for your state business license.
- Check name availability and reserve/register:
- Business name search: SOS Business Search (official).
- File an LLC online: fee 200∗∗;bymail:∗∗200**; by mail: **180: Form an LLC in Washington (official SOS portal).
- Corporations and other structures fees are listed here: SOS filing fees (official).
- Annual report: Due each year by the end of your anniversary month. Fee $60: SOS Annual Report (official).
- If you want a DBA/trade name: add it during your DOR BLS application. DOR charges $5 per trade name: DOR trade name info (official).
- Federal EIN: Most LLCs/corporations need one; sole proprietors often benefit too. Apply free with the IRS: Get an EIN (official IRS).
Reality check: Choosing the wrong structure can cost money later. If you’ll hire, take investment, or need liability protection, research before you click. The SOS processes filings quickly online, but errors (wrong registered agent, missing member info) can delay you.
What to do if this doesn’t work
- Call the SOS Corporations Division at 360‑725‑0377. Contact page: SOS Corporations & Charities (official).
- Get free legal basics from trusted sources: SBA — Choose a business structure (official), and consider a brief paid consult with a Washington business attorney if you’re unsure.
- If your online SOS filing is stuck, try mailing it (slower but sometimes smoother) or use a professional registered agent service (fees vary).
Step 2 — Get your Washington State Business License (UBI) via DOR BLS
This is your statewide license and the fastest way to generate your UBI number. You also attach city license endorsements here.
- Apply online (fastest): Apply for a Washington State Business License (official DOR BLS portal).
- Cost: DOR processing fee 19∗∗perinitialapplication;tradename∗∗19** per initial application; trade name **5 each; other endorsements add fees: DOR fee details (official).
- What you get: A UBI (Unified Business Identifier) and your state business license. You can also register for state taxes and add city endorsements (including Seattle).
- Processing time: Online applications are often processed within a few business days; paper takes longer. Official guidance: DOR BLS processing times and details.
- You’ll also set up your DOR account for taxes (sales tax, state B&O), and you’ll get filing frequency (monthly/quarterly/annual) based on estimated sales.
- Sales tax in Seattle varies by location; use the state’s tool to confirm the correct rate and location codes for each sale: DOR tax rate lookup (official).
- If you don’t sell taxable goods/services, you still may need to file state B&O. See classifications and rates: DOR B&O tax classifications and rates (official).
What to do if this doesn’t work
- Call DOR BLS at 360‑705‑6741. General taxpayer assistance line: 360‑705‑6705. Contact options: DOR contact us (official).
- If the online form throws errors, try a different browser or submit a paper application (slower). Download forms: BLS forms (official).
- For multilingual support, see: DOR language assistance (official).
Step 3 — Get your City of Seattle Business License (Business License Tax Certificate)
You need a Seattle city business license (a “general business license” or “business license tax certificate”) to do business in the city.
- Apply through DOR BLS by adding the “City of Seattle general business license endorsement”: Seattle city license endorsement (official DOR page).
- Who needs it:
- If your business is located in Seattle, you need the Seattle license regardless of revenue. City guidance: Seattle business licenses & taxes (official hub).
- If you are out‑of‑city but do business in Seattle under $2,000 per year, you may be exempt from the city general business license per the state city licensing threshold law; verify the current Seattle policy and threshold here: City general business license threshold rules (official DOR page).
- Fees: Seattle uses a tiered annual fee based on total worldwide gross revenue. Fee tiers change; verify the current schedule with the City: Seattle business license fee tiers (official Seattle page). The endorsement will appear in your DOR/BLS account with the correct fee.
- Renewal: City license endorsements renew annually through BLS. BLS sends renewal notices; due date is shown on your notice. City license cycles and penalties are managed by Seattle FAS: Seattle licensing — renewals and penalties (official).
- City B&O tax: Separate from the license fee. Most Seattle businesses file city B&O tax and any applicable local taxes via FileLocal: FileLocal (official). Tax classifications and rates: Seattle business license tax (B&O) classifications and rates (official).
Reality check: Seattle also collects the Payroll Expense Tax (“JumpStart”) from larger employers with significant Seattle payroll. Don’t ignore this if you’re scaling headcount and salaries. Details and thresholds are updated annually: Seattle Payroll Expense Tax (official).
What to do if this doesn’t work
- Seattle License & Tax Administration help: 206‑684‑8484; contact options here: Seattle License & Tax — Contact Us (official).
- If your DOR account doesn’t show the Seattle endorsement, remove and re‑add it or call DOR BLS at 360‑705‑6741.
- If FileLocal registration fails, use the support resources: FileLocal Support (official).
Step 4 — Register for taxes (state and city) and learn your due dates
Set this up right away so you don’t miss filings.
- State taxes (Washington DOR):
- Sales tax (if you sell taxable goods or services).
- State B&O tax (most businesses).
- File and pay in your DOR account. Monthly filers are generally due on the 25th of the following month; quarterly/annual filers have different deadlines. See: DOR due dates (official) and DOR filing frequencies (official).
- City taxes (Seattle FileLocal):
- City B&O tax and other local taxes or fees are filed via FileLocal: FileLocal (official).
- Due dates are shown in FileLocal and on the City’s tax pages; generally similar quarterly or annual cycles. City guidance: Seattle business license tax (official).
- Payroll Expense Tax (only for larger employers):
- Applies if you meet thresholds for total Seattle payroll and employee pay bands; thresholds/rates adjust annually. Check the current year specifics: Seattle Payroll Expense Tax (official).
- Federal taxes:
- Register with the IRS for an EIN if needed: Get an EIN (official IRS).
- Federal due dates vary by entity type (sole prop, partnership, S‑corp, C‑corp). See: IRS business tax due dates (official).
Taxes and filing due dates at a glance (verify in the linked sources):
Tax/return | Where to file | Typical due date | Source |
---|---|---|---|
State sales tax and state B&O | DOR (My DOR) | Monthly filers: 25th of following month; quarterly/annual differ | DOR due dates |
City of Seattle B&O | FileLocal | Quarterly/annual (see account) | Seattle business license tax |
Payroll Expense Tax (JumpStart) | FileLocal | Quarterly (see current year) | Payroll Expense Tax |
Federal payroll (if any) | EFTPS/IRS | Semi‑weekly/Monthly/Quarterly depending on deposits | IRS Employment Tax Due Dates |
What to do if this doesn’t work
- Call DOR (state tax) at 360‑705‑6705; Seattle License & Tax at 206‑684‑8484 for city tax questions.
- If you’re unsure about taxability or nexus, schedule a free consultation with DOR: Tax ruling/interpretation requests (official).
- Use FileLocal support for portal issues: FileLocal Support (official).
Step 5 — Check zoning, building, and occupancy (before you sign a lease)
- Verify your business use is allowed at the address. Seattle zoning and use lookup: SDCI Zoning & Land Use (official).
- Get required permits through the Seattle Services Portal:
- Building permits (tenant improvements), mechanical, electrical (through SDCI/SCL/SDOT as applicable).
- Sign permits.
- Change of use/occupancy when needed.
- Apply/track: Seattle Services Portal (official).
- Street/sidewalk use (outdoor dining, signage in right‑of‑way): Seattle Department of Transportation — permits (official).
- Fire permits (hazardous materials, assembly, etc.): Seattle Fire Department — permits and inspections (official).
- Timelines: Permit review times vary by scope and season. SDCI posts typical timelines and current backlogs: SDCI review times (official).
- Real‑world tip: Many new businesses find out too late that occupancy limits or ventilation requirements trigger design changes. Budget time and money for plan review and inspections.
What to do if this doesn’t work
- Talk to an SDCI permit specialist: 206‑684‑8850 or request coaching: SDCI Applicant Services (official).
- If your landlord is pushing a quick move‑in, protect yourself with a lease contingency for permits/occupancy.
- If you need design help, consult a Seattle‑experienced architect/engineer early. For accessibility questions (ADA), see: ADA small business guidance (ADA.gov).
Step 6 — Health and safety if you handle food or the public
Food and beverage operations must work with Public Health — Seattle & King County.
- Food establishment permits (restaurants, food trucks, caterers, groceries): Public Health — Food permits (official).
- Food worker cards: Required for staff who handle food; training and test are online. Statewide fee $10 (set by RCW): Washington Food Worker Card (official DOH).
- Mobile food vending: Commissary requirements, plan review, and vehicle inspections apply. Start here: King County mobile food businesses (official).
- Liquor licensing (beer/wine/spirits): Processed by the Washington State Liquor & Cannabis Board (WSLCB). Municipal recommendation, inspections, and public notices can add time. Start here: WSLCB Liquor Licensing (official).
- Smoking/vaping and age‑restricted products: See DOR/LCB licensing for tobacco/vapor products and local restrictions: Tobacco & vapor products (official DOR overview).
- Fire safety and occupancy: Assembly uses and cooking operations often require Seattle Fire permits and inspections: Seattle Fire — permits (official).
What to do if this doesn’t work
- Public Health – Seattle & King County Food Protection Program: 206‑263‑9566. Main environmental health info: Food safety program (official).
- Pre‑application consults reduce surprises: request meetings with Public Health and SDCI together if you’re building a kitchen.
- If liquor licensing stalls, ask WSLCB which step is pending (local review, floor plan, or signs). Contact: WSLCB Contact (official).
Step 7 — Specialty licenses and industry rules
Use this matrix to find common Seattle/Washington endorsements beyond the basic city license.

Alcohol service/sales | Liquor license | WSLCB | Liquor licensing (official) |
Cannabis | Producer/processor/retailer license | WSLCB | Cannabis licensing (official) |
Tobacco/vapor products | Retail/wholesale licenses | DOR and/or WSLCB | Tobacco/vapor licensing (official DOR) |
Contractors | State contractor registration + Seattle permits as needed | L&I + SDCI | Register as a contractor (official L&I) |
Personal services (salon, barber, spa) | Cosmetology/barbering shop licenses | WA Department of Licensing (DOL) | Cosmetology licensing (official DOL) |

- Call the relevant agency’s licensing helpline (linked above) for pre-application checks.
- If Seattle rules seem unclear, contact the Seattle Office of Economic Development small business team at 206‑684‑8090: OED Small Business (official).
Step 8 — If you’ll have employees: employer accounts and labor laws
Washington has three core employer registrations beyond tax registrations: Unemployment Insurance (ESD), Paid Family & Medical Leave (ESD), and Workers’ Compensation (L&I).
Employer setup checklist
Task | Agency and link | Key notes |
---|---|---|
Unemployment Insurance (UI) account | ESD Employer Taxes (official) | File quarterly wage reports and pay contributions. Employer Help: 855‑829‑9243. |
Paid Family & Medical Leave (PFML) | PFML for Employers (official) | Shared premiums (annual rate changes). Quarterly reporting. PFML Help: 833‑717‑2273. |
Workers’ Compensation account | Open an L&I account (official) | Report payroll, pay premiums. L&I Help: 360‑902‑5800. |
New Hire Reporting | Washington New Hire Reporting (official) | Report within 20 days of hire. |
Labor posters | Required workplace posters (official L&I) | Post in a visible area (free PDFs). |
City of Seattle labor standards (higher than the state in many cases)
- Minimum wage (Seattle): The City sets higher rates by employer size and benefits. 2024 example: Schedule 1 (≥500 employees) minimum wage was $19.97; small employers had different options with tips/medical. Seattle adjusts annually. Current rates and rules: Seattle Minimum Wage Ordinance (official). For Washington statewide minimum wage (outside city ordinances), see L&I: WA minimum wage (official).
- Paid Sick and Safe Time (PSST): Required for most Seattle employers; accruals vary by size. Details: Seattle PSST (official).
- Secure Scheduling (if covered): Applies to large food/retail; predictable schedules and premium pay rules: Secure Scheduling (official).
What to do if this doesn’t work
- Employer law help and complaints in Seattle: Office of Labor Standards (OLS) — contact options here: Seattle OLS (official). OLS phone: 206‑256‑5297.
- ESD UI and PFML employer help lines: 855‑829‑9243 (UI) and 833‑717‑2273 (PFML).
- L&I workers’ comp account setup: 360‑902‑5800; employer resources: L&I Employer Guide (official).
Step 9 — Home‑based businesses in Seattle
Many Seattle entrepreneurs work from home. You still need to follow city rules.
- City license: You still need the Seattle business license if your business is located in Seattle: Seattle business licenses (official).
- Home occupation rules: Seattle’s Land Use Code restricts onsite client visits, signage, noise, and other impacts in residential zones. Review “Home Occupations” in the Seattle Municipal Code: Seattle Municipal Code — Home Occupations (official). For practical guidance, see SDCI home‑based business info: SDCI — Zoning and Land Use (official).
- Improvements and permits: Even small changes (e.g., ventilation for a home bakery) can require permits. Check with SDCI: 206‑684‑8850; SDCI permits (official).
- Sales tax and B&O: State/city taxes still apply for home‑based businesses. See DOR taxes (official) and Seattle B&O (official).
What to do if this doesn’t work
- If neighbors complain or you get a notice, call SDCI early to discuss compliance options: 206‑684‑8850.
- If your home use isn’t allowed, consider a co‑working or shared kitchen with proper zoning and permits.
- Free advising to pivot your model: WSBDC (official).
Step 10 — Costs and timelines: what to budget and when to expect approvals
Numbers here are the best available from official sources. Always verify current fees in the links, as some adjust annually.
Item | Fee | Typical timeline | Source |
---|---|---|---|
WA State Business License (BLS processing) | $19 | A few business days online | DOR BLS (official) |
Trade name (DBA) | $5 per name | Same as BLS | DOR BLS (official) |
LLC formation (online/by mail) | 200∗∗/∗∗200** / **180 | Online same‑day to a few days | WA SOS fees (official) |

FileLocal registration | No fee to register | Same day | FileLocal (official) |
Food worker card | $10 | Same day online | Food Worker Card (official) |
Food establishment permits | Varies by operation | Weeks to months incl. plan review | Public Health — Food permits (official) |
Liquor license | Varies by type | Often several months | WSLCB Liquor (official) |
SDCI building permits | Varies by scope | See current review times | SDCI timelines (official) |
What to do if this doesn’t work
- Ask each agency about expedited options or pre‑application meetings.
- Sequence work to avoid idle time (e.g., start Public Health plan review while SDCI processes your building permit).
- Use a checklist and calendar reminders for renewals and due dates. DOR and FileLocal let you opt into email reminders.
Step 11 — Taxes and filings: dates you’ll actually need
Avoid late penalties by knowing the calendar.
Filing | Frequency | Deadline | Where to file | Source |
---|---|---|---|---|
State sales tax & B&O | Monthly/Quarterly/Annual | Monthly often due 25th of next month; others vary | DOR (My DOR) | DOR due dates (official) |
City of Seattle B&O | Quarterly/Annual | See FileLocal account; typically end of month after period | FileLocal | Seattle B&O tax (official) |
Payroll Expense Tax (if applicable) | Quarterly | See current year schedule | FileLocal | Payroll Expense Tax (official) |
ESD Unemployment Insurance | Quarterly | Apr 30, Jul 31, Oct 31, Jan 31 | ESD eServices | ESD Employer Taxes (official) |
PFML | Quarterly | Apr 30, Jul 31, Oct 31, Jan 31 | PFML employer portal | PFML Employers (official) |

What to do if this doesn’t work
- If you miss a deadline, file and pay as soon as possible; interest and penalties accrue. Use DOR’s penalty relief request if you had reasonable cause: DOR penalty waivers (official).
- If your FileLocal account locks, contact support via the portal: FileLocal Support (official).
Real‑world examples (Seattle scenarios)
Example 1 — Home‑based graphic designer in Ballard
- Structure: Single‑member LLC (formed online with WA SOS for $200). EIN free via IRS.
- Licensing: Applied for WA State Business License and added the City of Seattle endorsement (through BLS). No food or specialty permits.
- Taxes: Registered for state B&O (service classification) in DOR; set to quarterly filing. City B&O filed annually through FileLocal due to low revenue.
- Timeline: LLC formed in 1 day; BLS/Seattle endorsement appeared within a few days; FileLocal registration same day. No SDCI permits needed.
- Lessons: Confirmed home occupation rules to ensure occasional client visits were within limits; kept signage off the property per code. Links: SDCI Zoning & Land Use (official); Seattle B&O tax (official).
Example 2 — Coffee cart operating downtown and at events
- Structure: Sole proprietor (kept it simple initially). State license via BLS; City of Seattle endorsement added.
- Permits: Mobile food unit plan review and commissary agreement through Public Health — Seattle & King County. Food worker cards ($10 each) for staff. Temporary change of location permits for events as needed.
- City: Filed city B&O via FileLocal. No SDCI building permit (mobile), but obtained fire inspection sign‑off for propane equipment during health permit process.
- Timeline: Health plan review took several weeks; cart opening aligned with permit approval. Link: Mobile food businesses (official).
- Lessons: Commissary availability is a bottleneck. Getting on a commissary waitlist early helped avoid delays.
Example 3 — Small craft bar in Capitol Hill
- Structure: Corporation with multiple owners. Hired an attorney for lease/LLC docs and a permit runner for SDCI.
- Licensing: State (BLS), City (Seattle endorsement), plus WSLCB liquor license. SDCI tenant improvement permits for interior build‑out; Seattle Fire assembly permit; Public Health permit for limited food menu.
- Taxes: State and city B&O; later became subject to Payroll Expense Tax after headcount/salary growth — reviewed thresholds annually: Seattle Payroll Expense Tax (official).
- Timeline: Several months end‑to‑end due to construction and liquor licensing.
- Lessons: Built a 90‑day cash buffer for rent and carrying costs during permit and license waits. Sequenced inspections to avoid rework.
Common mistakes to avoid
- Applying for the Seattle city license before forming your LLC/corporation, then having to fix names and UBI links later.
- Signing a lease before SDCI confirms your use is allowed, parking minimums (if any) are met, and ventilation/grease requirements are clear.
- Missing the city’s Payroll Expense Tax thresholds when you scale — an expensive surprise for high‑salaried teams.
- Assuming your sales are non‑taxable. Washington taxes many services; verify at DOR and get a written ruling when unclear.
- Registering the wrong NAICS code, causing the wrong city or state B&O classification and mismatched rates.
- Not setting up FileLocal early; you’ll need it for city B&O and other local taxes.
- Food businesses skipping pre‑application consults with Public Health and SDCI — plan review turns up design changes that cost time and money.
- Forgetting the WA SOS Annual Report (fee $60) — late filings can lead to administrative dissolution.
- Relying on outdated fee charts in blogs — always verify with official links (DOR, Seattle FAS, SDCI, WSLCB).
- Ignoring labor ordinances (Seattle minimum wage, PSST, scheduling) — audits and penalties can stack up. Use OLS resources early.
What to do if this doesn’t work
- Book free one‑on‑one advising at WSBDC or ask OED to connect you to technical assistance: 206‑684‑8090.
- If you’re stuck between agencies (DOR vs Seattle vs Public Health), ask for a joint meeting or email thread to align requirements.

- Apply for your Washington State Business License (BLS) — fee $19 — and add your Seattle city license endorsement: DOR BLS (official).
- Set up tax accounts:
- DOR (state sales tax & B&O)
- FileLocal (Seattle B&O, payroll expense if applicable)
- If you’ll hire: set up ESD UI, PFML, and L&I workers’ comp accounts. Post required labor posters (free).
- If you sell or serve food/alcohol: start Public Health plan review and WSLCB process. Get food worker cards ($10 each).
- Before you sign a lease: confirm zoning and permit requirements with SDCI; plan for construction permits and inspections.
- Calendar your renewals and filings:
- DOR tax returns (often due 25th monthly)
- FileLocal (quarterly/annual)
- SOS Annual Report ($60) by end of anniversary month
- City license renewal (see BLS notice)
What to do if this doesn’t work
- If any step causes a chain delay (e.g., you need the UBI to add the city endorsement; you need permits before inspection), pause and resolve the blocker before moving on.
- Ask for a joint agency touchpoint (DOR + City + SDCI) if requirements seem to conflict.
Industry spotlights (Seattle realities)
Food service (brick‑and‑mortar)
- Critical path items are health plan review, SDCI permits, and WSLCB (if alcohol). Each can take weeks to months; start in parallel and engage professionals.
- Budget for make‑up air, grease management, and fire suppression — expensive surprises. Links: Public Health Food plan review (official), SDCI permits (official), Seattle Fire permits (official).
Retail shop
- Sales tax setup and location code selection are top priorities. Use DOR’s rate lookup for each POS location: DOR rate lookup (official).
- If you use sidewalk displays or sandwich boards in the right‑of‑way, you likely need SDOT permits: SDOT permits (official).
Professional services
- Don’t assume “no taxes.” State B&O applies to most service businesses. Confirm your classification and rates: DOR B&O tax (official).
- If you’re fully remote but located in Seattle, you still typically need the Seattle city license and may owe city B&O depending on gross receipts/credits: Seattle B&O (official).

- UBI (if already assigned) or entity info
- Physical/mailing addresses
- NAICS code
- Trade names ($5 each)
- City endorsements (Seattle, etc.)
- Estimated revenue (sets filing frequency)
- Payment card

What to do if this doesn’t work
- If you don’t know your NAICS, use DOR’s lookup tool in the application or the Census NAICS search: NAICS Search (official).
- If your card fails, try a different browser, card, or use mail‑in forms (slower but reliable).
Reality checks, warnings, and pro tips
- Timeline drift is real. City and county workloads vary; summer/fall often run longer for plan review.
- Build a cash buffer. Carrying rent and payroll during permitting can sink new businesses. A 60–90 day cushion for brick‑and‑mortar is common.
- Document everything. Keep PDFs of filings, approvals, and inspection reports. If questions arise, you’ll resolve them faster.
- Use official calculators and lookups. Guessing sales tax rates or B&O classifications leads to back taxes and penalties. Use DOR rate lookup (official) and DOR B&O guidance (official).
- Read Seattle’s city tax pages before you scale headcount and salaries in the city. JumpStart Payroll Expense Tax thresholds/rates update annually: Payroll Expense Tax (official).
What to do if this doesn’t work
- Ask for a written clarification from the agency (email) and keep it. If audited, a written answer helps.
- Engage a Washington CPA who knows Seattle’s city taxes for a 1–2 hour consult. It’s cheaper than a penalty letter.
