Washington compliance for multi-member LLCs

Research steps and summary: Steps taken Research steps and summary: Steps taken Performed multiple targeted web searches (Secretary of State, Department of Revenue, Department of Labor & Industries, Employment Security Department, IRS, and recognized legal/compliance resources) to collect authoritative, state-specific compliance requirements for multi-member LLCs formed or doing business in Washington State.

Prioritized official state pages (Washington Secretary of State — Corporations & Charities division, Washington Department of Revenue / Business Licensing Service, Washington L&I, Employment Security Department) and key federal resources (IRS) and reputable compliance/legal guides for practical details.

Extracted and compiled verbatim guidance and key facts (fees, deadlines, required registrations, filings, and penalties) from these sources so the content can be used to produce a comprehensive blog/newsletter about Washington compliance for multi-member LLCs.

Key findings and summary of Washington compliance requirements for multi-member LLCs (authoritative, actionable points) Formation & basic state filings - Certificate of Formation File a Certificate of Formation with the Washington Secretary of State to create a Domestic LLC; the Secretary of State filing fee is $180 (online filing available). (SOS citations below). - Registered Agent: Washington requires every LLC to designate a Registered Agent with a Washington street address (commercial or noncommercial) when filing. (SOS citations). - Initial Report: The initial report is due within 120 days of the effective date of the Certificate of Formation (the online filing flow shows a "Defer Initial Report" checkbox and explains the 120-day initial report requirement). (SOS citations). - Annual Report / Ongoing filings: Washington LLCs must file an annual report each year by the end of the LLC’s registration anniversary month (SOS guidance).

Sources and compliance guides indicate an online annual-report filing fee and note late-filing penalties and risk of administrative dissolution if required filings are not made. (SOS and Harbor Compliance citations).

State business registration, UBI, and licensing - Unified Business Identifier (UBI): The Secretary of State filing will result in a UBI, which is the business identifier used by WA state agencies. Use the Business Licensing Service / Master Business Application to register tax and licensing endorsements with DOR, L&I, ESD, and local jurisdictions where required. (SOS and DOR citations). - Business License / Master Business Application: Register with the Washington Department of Revenue Business Licensing Service (Master Business Application) if conditions apply (e.g., gross income $12,000+ per year, hiring employees within 90 days, selling taxable goods/services, or doing business under a name other than the owner’s full legal name).

DOR notes variable processing fees and specific fees for opening a new business or registering a trade name. (DOR citations). State taxes and excise taxes - B&O tax and other excise taxes: Washington does not have a corporate income tax but imposes Business & Occupation (B&O) tax on gross receipts and other excise taxes.

Businesses that meet thresholds (e.g., sales tax collection, gross receipts) must register with the Department of Revenue. (DOR B&O citation). - Sales & use tax: Register and collect sales tax where applicable; DOR registration required if selling taxable goods or services. (DOR citation).

Federal tax treatment & EIN - Federal classification: By default, an LLC with two or more members (multi-member LLC) is treated as a partnership for federal tax purposes (files Form 1065) unless it files an election to be taxed as a corporation (Form 8832) or as an S corporation (Form 2553). (IRS Form 1065 citation and secondary legal guidance citation). - EIN: A multi-member LLC must obtain a Federal Employer Identification Number (EIN) (Form SS-4) — required if the LLC has more than one member or has employees; EIN is commonly needed to open business bank accounts and file federal returns. (Harbor Compliance / IRS citations).

Employer obligations (if hiring employees) - Employment Security (ESD): Employers must register with the Employment Security Department for unemployment insurance and meet quarterly reporting obligations; DOR/Business Licensing integrates ESD endorsements through the Master Business Application. (DOR and ESD links cited). - Labor & Industries (L&I): Employers must register with Washington L&I for workers’ compensation and industrial insurance coverage; L&I enforces employer responsibilities for workplace safety and workers’ compensation. (L&I citation).

Local licensing and permits - City/county licenses and permits: Many cities and counties require local business licenses or permits; the Master Business Application and DOR resources explain how to find applicable local requirements. (DOR and Puget Law citations).

Foreign LLCs and qualifying to do business in WA - Foreign Registration: Out-of-state LLCs (foreign LLCs) planning to transact business in Washington must file a Foreign Registration Statement with the Secretary of State (fee information and online filing available; fee similar to domestic filings). (SOS citation).

Other compliance topics to address in content - Operating Agreement: Although Washington does not require a written operating agreement, strong practical guidance recommends drafting one to define member rights, voting, capital contributions, allocations, distributions, transfer restrictions, buy-sell provisions, and dissolution process. (legal guidance citation). - Beneficial Ownership / FinCEN BOI: Entities including many LLCs must report beneficial ownership information to FinCEN under the Corporate Transparency Act; initial deadlines vary based on formation date. (Harbor Compliance excerpt referencing BOI/FinCEN). - Penalties & risk: Late or missing annual reports, failure to register for required taxes/endorsements, or failure to maintain required employer coverage can trigger late fees, assessments, administrative dissolution, or enforcement actions. (SOS and DOR citations).
