Cheapest LLC Formation Services in Washington (2026)

For most Washington founders, ZenBusiness is the service to start with. It files your Certificate of Formation for $0 plus the state fee, includes a year of its Worry-Free Compliance service, and runs everything through a dashboard that's genuinely easy to navigate — a strong combination of low price, included tooling, and responsive support for a first LLC. It earns the top spot below on substance, not just sticker price.

Here's how the leading services compare for a Washington LLC, ranked by overall value.

ZenBusiness pairs a genuinely free base filing with the most useful compliance tooling in the category, which is exactly what a Washington owner watching the state's $200 formation fee and recurring $70 annual report wants.

Key features: $0 formation plus the state fee; Worry-Free Compliance (free the first year) that tracks deadlines and can file your Washington annual report for you; registered agent service available; EIN and operating agreement on the paid tiers; a modern dashboard and mobile app that keep documents and status in one place.

Best for: First-time founders who want the lowest realistic entry cost plus ongoing help staying compliant.

Pricing tier (as of 2026): Starter is $0 plus the state fee; the Pro tier runs roughly $199 a year and Premium around $349, both renewing annually. Registered agent service is about $199 a year and is frequently bundled with compliance at a first-year discount.

Pros: The base formation filing really is free; the compliance automation is the strongest among mainstream services; the interface is easy for non-experts; phone and chat support are responsive; and the company has formed well over 500,000 businesses.

Cons: A registered agent and EIN are paid add-ons rather than included, and the Pro and Premium tiers auto-renew — so it's worth knowing exactly what recurs before you check out.

Northwest is the value-and-privacy pick, folding a full year of registered agent service into a low flat fee.

Key features: $39 plus the state fee, with one year of registered agent service included; its "Privacy by Default" approach keeps your information off public-facing records where possible; same-day document scanning; and customer support that consistently earns praise for being knowledgeable and unscripted.

Best for: Owners who put a premium on privacy and want a registered agent in place from day one.

Pricing tier (as of 2026): $39 plus the state fee to form, with registered agent service renewing at about $125 a year — the lowest renewal among the major names here.

Pros: Registered agent included the first year; strong privacy practices; flat, predictable pricing; and notably few upsells during checkout.

Cons: It offers fewer built-in compliance-automation tools than ZenBusiness, add-ons like an EIN cost extra, and the interface is plainer than the SaaS-style dashboards of newer competitors.

Bizee leads on the lowest first-year out-of-pocket, with a free year of registered agent service attached to a $0 filing.

Key features: $0 formation plus the state fee; registered agent free for the first year; lifetime company alerts for compliance reminders; a simple formation wizard; and a long track record (more than a million businesses formed across its Incfile and Bizee history).

Best for: Bootstrappers who simply want the smallest possible bill in year one.

Pricing tier (as of 2026): $0 plus the state fee to form. Registered agent renews at roughly $119 a year, or runs about $199 if purchased separately later.

Pros: Free registered agent the first year, very low entry cost, and faster filing options on paid tiers.

Cons: Customer support can be slow to reach, the checkout flow pushes add-ons, and the ongoing compliance tooling is lighter than what ZenBusiness builds in.

Tailor Brands bundles formation with real branding tools, which sets it apart for someone launching a brand-new venture rather than just registering an entity.

Key features: A $0 Lite formation tier plus the state fee; an AI-driven logo maker; a basic website builder; design assets like business cards; and compliance alerts on the higher tiers.

Best for: Brand-new businesses that need a logo and a simple website alongside the LLC, in one place.

Pricing tier (as of 2026): Lite is $0 plus the state fee; paid plans run roughly $199 to $249 a year. Registered agent service is a $199-a-year add-on on every tier, and an EIN runs about $99.

Pros: The branding tools are genuinely useful and a real differentiator, chat support is fast, and the all-in-one bundle saves time for new brands.

Cons: Registered agent is never included, the EIN add-on is priced high relative to the market, and anyone who only needs LLC filing ends up paying for tools they may not use.

LegalZoom is the most recognized name in the space, and its draw is the breadth of legal services that sit beyond formation.

Key features: A $0 Basic formation tier plus the state fee; attorney consultations on its premium plan; trademark, contract, and estate services under the same roof; and add-on tax help.

Best for: Owners who expect to need legal services beyond the LLC itself and want them under one familiar brand.

Pricing tier (as of 2026): Basic formation is $0 plus the state fee; the Pro tier runs about $249. Registered agent service is roughly $249 a year — the highest among the major providers here.

Pros: Strong brand trust, a wide legal-services catalog, and attorney access on the top tier.

Cons: The most expensive registered agent in this comparison, a checkout known for aggressive upsells, and a general sense that you're paying a premium for the name rather than a better filing.

Rocket Lawyer is built around a legal-services membership, and its formation value really turns on whether you'll use that subscription.

Key features: A $99.99 one-time formation for non-members (free with membership); an extensive document library; on-demand attorney questions; and registered agent service for subscribers.

Best for: Owners who'll regularly draw on legal documents and advice, not just file once and move on.

Pricing tier (as of 2026): $99.99 to form as a non-member, or free with the membership at about $39.99 a month. Registered agent service runs roughly $149.99 a year, with a member discount.

Pros: Excellent document and attorney access for active members, and the first business registration is free once you subscribe.

Cons: The "free" formation depends on keeping a paid membership, and standalone formation costs more than the free-tier options above.

Once you account for Washington's own costs — the $200 online formation fee, the recurring $70 annual report, and a B&O tax that applies regardless of profit — the service that keeps your side of the ledger lowest while handling the parts that trip people up is the one worth choosing. Northwest is the strongest pure-privacy and flat-fee alternative, and Bizee wins on raw first-year price; both are credible picks. But for the typical Washington owner forming a first LLC, ZenBusiness offers the best balance of a free base filing, built-in compliance that actually files your annual report, an interface anyone can use, and support that answers when you call. Start there, add a registered agent if you'd rather keep your home address off the public record, and you'll have a properly formed Washington LLC for very close to the lowest realistic cost available in 2026.
