Why Choose a Washington LLC?

Washington’s Limited Liability Company Act (RCW 25.15) was rewritten to be contract-friendly, enforce operating agreements, and align with the Uniform Business Organizations Code (RCW 23.95). Combine that with online filings, built-in expedite options, and no state income tax, and a WA LLC becomes the default for founders who actually live or operate here.

🌲Best-Fit Scenarios

  • WA-based founders who need bank-ready documentation, registered agents, and B&O accounts set up fast.
  • Remote professionals relocating from CA/NY/TX who want no income tax but understand B&O filings.
  • Real-estate and short-term rental operators holding property in Seattle, Tacoma, Spokane, or the islands.
  • Professional practices (legal, medical, architecture) using PLLCs to satisfy licensing board rules.

⚠️Where WA Isn’t Magic

  • Attempting to dodge another state’s taxes while maintaining nexus there—you still foreign-qualify and pay.
  • Series LLC structures—WA rejected the Uniform Protected Series Act, so Delaware/Texas series must register as standard LLCs.
  • Anonymous filings—SOS public records list RA information and initial governors/members; CTA rules may return.
  • High revenue without margins—B&O tax hits gross receipts regardless of profitability.

❌ Myth: “No income tax = tax-free Washington LLC”

Washington’s lack of an income tax does not mean your LLC avoids state levies. The gross-receipts B&O tax still applies to almost every business, even if you lose money, and major cities stack their own B&O on top. If you live in California or Oregon, those states continue to tax your worldwide income regardless of where the LLC is formed.

✓ Reality: Form in WA when your business already lives here

Use a Washington LLC when you have office space, property, employees, or resident owners in the state. It aligns your registered agent, UBI, DOR accounts, and PLLC licensing, and avoids the double cost of “out-of-state LLC + WA foreign registration.” It also supports community-property planning for married owners.

⚖️Washington vs Other Popular LLC States

When clients ask “Should I form in Washington or somewhere more ‘famous’ like Delaware or Wyoming?” this is the comparison I actually walk them through. Numbers are approximate and change over time, but the pattern is what matters.

State Formation Cost (LLC) Annual State Cost Income Tax? Practical Notes
Washington ≈ $200 online (COF) + optional $30 name reservation $70 annual report (plus B&O filings if doing business in WA) No state income tax, but B&O on gross receipts Best when you actually live or operate in WA. B&O can bite low-margin businesses. No series LLC statute.
Wyoming ≈ $60 formation cost Low annual franchise fee; privacy + asset-protection marketing No state income tax Attractive for holding companies, but if you live in WA or CA you still owe home-state tax and must foreign-register where you really operate.
Delaware ≈ $110 formation cost Annual franchise tax + RA fees State income tax applies for in-state activity Excellent courts and investor familiarity for venture-backed companies, but overkill for a local WA consultant who never plans to raise VC.
California ≈ $70 formation cost $800 LLC tax + $20 statement of information Yes (personal and corporate) If you live and work in California, you are “doing business” there regardless of where the LLC is formed. California is the default for purely California-based businesses.

Takeaway: Washington wins for Washington-centric operations. Delaware and Wyoming have their role, but not as magic shields against your home state’s tax and jurisdiction rules.

When Washington is not your silver bullet

  • California nexus: Forming in WA doesn’t relieve you from CA’s $800 LLC tax or franchise filings if you live or operate there.
  • Low margin, high revenue: B&O taxes gross receipts even when you lose money, so plan for effective rates exceeding 10% for services.
  • No series statute: Delaware/Texas series must reorganize; WA offers only single-entity liability protection.
  • Transparency: RA info is public, and FinCEN can restart BOI reporting—don’t promise anonymity.
Primary source anchor: RCW 25.15 (LLC Act) + RCW 23.95 (UBOC). File, amend, and report through the Corporations & Charities Filing System; your nine-digit UBI also controls Department of Revenue accounts and city licensing integrations.

Statute & Certificate of Formation Essentials

RCW 25.15.071 spells out the content of every Washington Certificate of Formation. RCW 23.95 (UBOC) supplies naming standards, registered agent rules, periodic reports, and foreign-registration mechanics.

Required Contents of the Certificate of Formation (RCW 25.15.071)

RequirementRCW cite / SOS notePractice tips
NameRCW 25.15.071(1)(a); RCW 23.95.300–305Use “LLC”, “L.L.C.”, etc. Distinguish from existing names by more than punctuation; add geographic/industry modifiers if needed.
Registered agent + addressRCW 25.15.071(1)(b); RCW 23.95.415No PO boxes. Upload consent or use the online RA acceptance. Mis-typing addresses causes service failures.
Principal officeRCW 25.15.071(1)(c)Can be out of state. DOR cross-checks it against your business license application.
Duration & effective dateRCW 25.15.071(1)(d)Perpetual default. Set a delayed effective date (up to 90 days) if coordinating closings.
Organizer / executor infoRCW 25.15.071(1)(e)Organizer can be your attorney or RA. Banks often want the first member listed even if not required.
Management statementRCW 25.15.071(1)(f)Check “manager-managed” if you plan to appoint managers; failing to do so causes confusion later.
Optional provisionsRCW 25.15.071(1)(g)Use for PLLC profession language, liability limitations, or indemnity disclaimers; keep trade secrets out of the public record.

Naming rules under RCW 23.95

Names must be distinguishable on SOS records, avoid misleading professional words, and include an LLC designator. You can reserve a name for 180 days (Form NR, $30). The name rejection list includes banking words, government references, and words requiring board approval (e.g., “engineer”, “architect”).

Registered agent requirements

Every LLC must maintain a registered agent located at a physical Washington address (RCW 23.95.415). Agents must keep normal business hours. Commercial RA services typically run $120–$200/year; individuals can serve but must stay available for process servers, which is risky for remote owners.

Professional LLCs / PLLCs

PLLCs file the same certificate but must state the profession (e.g., “to practice law in Washington”) and comply with the relevant licensing board. Only licensed professionals may be members/managers, and the operating agreement must address what happens when someone loses their license. Some boards (e.g., WSBA, Department of Health) require copies of your filings or additional approvals.

Foreign LLC registration

Foreign LLCs transacting business in Washington must file a Foreign Registration Statement (RCW 23.95.505) and pay the same $200 online fee. Trigger events include having employees, inventory, or offices in WA. Failure to register bars you from maintaining lawsuits until you cure, and DOR can assess penalties for unlicensed activity. Once registered, you file the same $70 annual report and maintain a WA registered agent.

Filing options & turnaround

MethodFeeExpediteTurnaroundUse case
Online via CCFS$200Included1–2 business days (often same day)Default for most filings; initial report can be included.
Mail / in-person standard$180None3–4 weeksOnly use if you need to attach extra documentation the portal doesn’t support.
Mail / in-person expedited$180 + $100$100 surchargeSame day to 2 business daysFor unusual filings (e.g., court orders) requiring paper submission but time-sensitive results.
📄 Filing Tips & Common Mistakes
  • Mark “manager-managed” if you will use managers—fixing later requires an amendment.
  • Use the same principal office address on your DOR business license; mismatches trigger verification requests.
  • When appointing an individual RA, ensure they understand process servers may arrive at their home.
  • Keep a PDF of the stamped certificate, RA consent, and initial report; banks and investors frequently request them.
Foreign entities reminder: RCW 25.15.500–.540 outline penalties for transacting business without authority. Besides being unable to maintain a lawsuit, you may owe back B&O tax, city license fees, and a $140 reinstatement fee to cure delinquent status. Register before opening offices, hiring employees, or storing inventory in Washington.

Formation Checklist

This is the workflow I use for WA LLCs and PLLCs. Everything is handled online unless you have a special filing (e.g., recordation, court order, tribal entity, etc.).

1

Step 1 – Name & Reservation

Run name searches in CCFS and secure the matching domain/social handles. If you need extra time (fundraising, licensing), file the $30 name reservation (Form NR) to lock it for 180 days. Avoid restricted terms unless you have board approval.

2

Step 2 – Registered Agent Strategy

Choose between a commercial RA (recommended for non-residents) or a trusted individual with a WA street address. Agents must be available during business hours and willing to receive subpoenas—plan accordingly.

3

Step 3 – Certificate of Formation & Initial Report

File online via CCFS for $200; the system automatically expedites. Include the initial report in the same session (free) to avoid the $10 later filing. PLLCs insert their profession (“to practice dentistry in Washington”) in the optional clauses.

4

Step 4 – Operating Agreement & Organizational Actions

Adopt an operating agreement covering capital contributions, management, transfer restrictions, fiduciary duty modifications, and PLLC requirements. Execute resolutions admitting members, appointing managers/officers, authorizing EIN filings, and opening bank accounts.

5

Step 5 – EIN, UBI & Tax Accounts

Obtain an EIN from the IRS. Register with the WA Department of Revenue to either obtain or confirm your Unified Business Identifier (UBI) and to open B&O and sales/use tax accounts. Most cities require a local license once you receive the state master business license.

6

Step 6 – Banking, Accounting & Calendars

Provide your bank with the stamped certificate, OA, and resolutions. Set up accounting software (QuickBooks, Xero) and calendar B&O filings, annual report deadlines, and city license renewals. Document member reimbursements and loans to avoid commingling.

7

Step 7 – Foreign Registration (if needed)

If you operate in Oregon, California, Idaho, or elsewhere, foreign-qualify now while the WA documents are fresh. Each state will need a Certificate of Good Standing from WA (order via CCFS) and its own registered agent.

🩺 Folding Window – Professional LLC Checklist
  • Confirm licensing board rules (WSBA, DOH, Board of Accountancy, etc.) permit PLLCs and whether they require separate registration.
  • All equity holders and managers must hold active licenses; outline buyout/redemption if a member is disciplined or leaves the profession.
  • Some boards demand copies of the OA, insurance certificates, or surety bonds—budget extra time for board review.

Operating Agreement & Fiduciary Duties

RCW 25.15 emphasizes contractual freedom but retains non-waivable duties: the obligation of good faith and fair dealing and minimum standards of loyalty. Draft your operating agreement as if a judge will read it—because in Washington, they often do.

Default vs. customized duties

Default duties: RCW 25.15.038–.0385 codify loyalty (account to the company, refrain from competing, avoid self-dealing without consent) and care (avoid gross negligence or reckless conduct). The OA can specify safe harbors for certain transactions, reduce liability for ordinary negligence, and define conflict-of-interest procedures. The duty of good faith and fair dealing cannot be waived.

Member-managed vs manager-managed

Member-managedManager-managed
Use caseFamily rentals, professional practices where all owners are active.Startups with passive investors, multi-property portfolios needing centralized control.
AuthorityEach member can bind the LLC unless OA restricts it.Managers have authority; members vote only on major decisions.
Fiduciary dutiesAll members owe duties to each other and the LLC.Managers owe duties; non-manager members only owe limited obligations.

Capital contributionsDocuments cash, property, services, and future funding obligations.RCW 25.15.451 enforces contribution obligations; specify penalties for failure.
Vesting / sweat equityIncentivizes founders providing services over time.Use repurchase formulas tied to fair value; address payroll tax implications.
Capital callsAllows the LLC to request additional funds.Reference RCW 25.15.460–.495; define dilution or default remedies.
Distributions & tax allocationsSets cash waterfall and tax distributions.Plan for B&O and city tax reserves before member draws.

Deadlock & dispute resolutionResolves 50/50 stalemates.RCW 23.95.525 permits WA-only forum clauses; include mediation/arbitration steps.

PLLC-specific OA issues

  • Ownership limits: Only licensed professionals may own or manage; include automatic redemption if a member loses their license.
  • Professional liability: Members remain personally liable for their own malpractice—ensure OA references insurance and personal guarantees.
  • Board compliance: Some boards (e.g., WSBA, DOH) require copies of amendments; build that filing obligation into the OA.
📂 Folding Window: Additional drafting highlights
  • Include B&O tax reserves so distributions don’t outpace cash needs.
  • Use WA forum-selection and arbitration clauses to keep disputes local.
  • For S-corp elections, add compliance language (single class of stock, eligible members).
  • Consider putting CTA/BOI obligations (if reintroduced) into the OA so members must share ID promptly.

B&O Tax, Local Taxes & Annual Compliance

Washington waives income tax but imposes gross-receipts B&O taxes at both state and (often) city levels.

💼B&O Overview

ClassificationApprox. rateExamples
Retailing0.471% → 0.5%E-commerce selling to WA customers, storefront retail, restaurants.
Wholesaling / Manufacturing~0.484%Manufacturers producing goods in WA, distributors shipping product to retailers.
Service & Other1.5%–1.75%SaaS, consultants, lawyers, healthcare providers, creative agencies.
Royalties / apportionable income1.5%–1.75%Software licensing, digital content, international revenues.

Register with the Department of Revenue to receive/confirm your UBI and open excise (B&O/sales) tax accounts. Filing frequency depends on revenue: monthly for high-volume businesses, quarterly or annually for smaller ones. Even $0 returns must be filed to avoid penalties. The small business credit can reduce or eliminate B&O for startups—check current thresholds each January.

🗓️Compliance Calendar

RequirementDeadlineFee / penalty
Initial ReportWithin 120 days of formation$0 with formation / $10 if separate
Annual ReportLast day of anniversary month$70 ($25 late fee + dissolution risk)
DOR Excise/B&O ReturnMonthly/quarterly/annual based on assignmentPenalties start at 5% per month + interest
City B&O ReturnsUsually quarterly (Seattle/Tacoma/Bellevue)Varies by city
CTA MonitoringAs rules changeCurrently $0, but keep ownership records ready

Scenario: Solo consultant earning $150k

Even with all clients out-of-state, WA taxes the gross receipts under the Service & Other classification (~1.75%). Seattle-based consultants owe city B&O if revenues exceed the city threshold (moving to $2M in 2026 but with higher rates).

Scenario: Amazon seller shipping nationwide

Your WA nexus from warehousing inventory triggers both state retailing B&O and sales tax collection. Sales to other states may require marketplace facilitator compliance but do not remove WA obligations. City B&O applies if you operate within a city boundary.

Local B&O / city licenses: Seattle, Tacoma, Bellevue, Bellingham, Olympia, and dozens of other cities impose their own B&O tax and licensing regimes. Rates fluctuated upward in 2024–2025, while Seattle’s exemption threshold is slated to hit $2M in 2026. You often file these returns through the DOR city portal, but some cities require direct filing. Expect a second layer of gross-receipts tax if you operate inside those city limits.
Missed deadlines: Skipping the annual report pushes the LLC to "administratively dissolved" status, requiring a $140 reinstatement fee plus back reports—banks can freeze accounts until reinstated. Late B&O returns accrue penalties (5% → 25%) and interest rapidly; DOR can garnish accounts if multiple returns are skipped. Keep reminders synced with your accounting software.

Corporate Transparency Act / Beneficial Ownership Status

FinCEN’s March 2025 interim rule temporarily exempted all domestic entities from BOI reporting. Washington LLCs and corporations formed under state law currently have no CTA filing duty, but foreign entities formed abroad and registered here still need to pay attention.

Current rule (as of 2025): Domestic WA LLCs/corps are not “reporting companies.” Foreign entities (organized outside the U.S.) that register to do business in WA remain “foreign reporting companies,” but FinCEN no longer requires them to disclose U.S.-person beneficial owners. The Treasury can reinstate broader reporting with a new rule or after litigation, so keep owners’ data organized.

📢What to keep on file anyway

  • Copies of government ID (passport/driver license) for each member/manager.
  • Legal names, addresses, and ownership percentages for all beneficial owners.
  • Control-person info (managers, managing members, senior officers).
  • Historical records of transfers or ownership changes.

This ensures you can refile quickly if FinCEN reactivates domestic reporting.

🧭Operating agreement clauses

Add language requiring owners to deliver BOI info within a fixed number of days if reporting restarts, and authorize the manager to file on behalf of members using that information. Include penalties (fines or forced buyouts) for members who refuse to provide data—FinCEN’s civil penalties fall on the company if you cannot report.

✍ Suggested clause concepts
  • Members consent to providing personal identification within five business days of written request for CTA compliance.
  • Managers may rely on member-provided information and file BOI reports on behalf of the LLC.
  • Failure to provide information constitutes a breach allowing suspension of distributions or forced redemption.
