Forming an LLC in Washington takes nine steps, and eight of them look like every other state's process: pick a name, appoint a registered agent, file with the state, get an EIN. The ninth is the one that surprises people.
Washington State runs LLC registration through two separate state systems, not one. The Secretary of State handles your Certificate of Formation. A separate agency, the Department of Revenue, handles the business license almost every operating LLC ends up needing.
Skip the second one and your business is only half registered, even though your LLC technically exists.
That's not a compliance trap. It's a short extra step, and this guide walks through exactly when you need it, what it costs, and where it fits alongside the rest of the filing.
If you're comparing formation options before you commit to a state, our breakdowns of the cheapest way to form an LLC and the best LLC formation services cover how Washington stacks up against the rest of the country.
Key takeaways
Budget around $230 for year one: a $180 Certificate of Formation filed with the Secretary of State, plus a Washington State Business License (starting at $50) filed with the Department of Revenue.
Washington splits LLC registration across two agencies. The Secretary of State forms the entity; the Department of Revenue issues the business license most operating LLCs need to run.
Washington has no personal or corporate income tax, a real draw for founders comparing states. It does levy a Business and Occupation (B&O) tax on gross revenue, with no deduction for expenses, so it applies whether or not you're profitable.
Once you're formed, plan on a $70 Annual Report every year and keeping your registered agent and business license current.
What a Washington LLC actually is, and its real benefits
An LLC (limited liability company) is a business structure that separates your personal assets from your business's debts and liabilities, while letting profits pass through to your personal tax return instead of facing a separate entity-level tax.
Washington adds two real benefits on top of that baseline. There's no personal or corporate income tax anywhere in the state, which matters if you live and operate here.
The Secretary of State's filing itself is fast and inexpensive too: a $180 flat fee, with no tiered pricing based on how many members your LLC has.
Before you assume Washington is the cheapest state, one nuance matters. The no-income-tax benefit only helps founders who live and do business there.
Forming a Washington LLC while you live and work somewhere else doesn't exempt you from your home state's income tax. Tax nexus generally follows where the money is made and where the owner lives, not where the entity is chartered.
And Washington isn't tax-free. The state's Business and Occupation tax is a gross-receipts tax, not an income tax, so it can apply even in a year your business doesn't turn a profit. Plan for it as a real cost of doing business here, not a footnote.
LLC vs. C corp vs. S corp vs. sole proprietorship
LLC | C corp | S corp | Sole proprietorship | |
|---|---|---|---|---|
Created by | Certificate of Formation, WA Secretary of State | Certificate of Incorporation, WA Secretary of State | IRS election (Form 2553) on top of an underlying corp or LLC | No state filing required |
Washington formation fee | $180 | Filed through the same WA Secretary of State system; fee varies by entity type | Same as the underlying entity, no separate state fee for the election itself | $0 |
Owners | One or more members | Shareholders, unlimited | Up to 100 shareholders, must be US persons | One owner |
Personal liability | Limited | Limited | Limited | Unlimited, no separation from personal assets |
Default taxation | Pass-through, on the member's personal return | Entity-level tax, plus tax on dividends | Pass-through | Pass-through (Schedule C) |
Can raise VC funding | Rare; VCs generally require a C corp | Yes, the standard structure for VC-backed startups | No, shareholder restrictions rule it out | No |
Best fit | Founders who want liability protection and flexible taxation, without VC plans | Startups raising institutional or VC money | Established small businesses managing self-employment tax | Solo, low-risk businesses testing an idea |
If venture funding is part of your plan, a Delaware C corp is the structure investors expect to see. Our guide to what a C corp actually is breaks down why, and what changes if you convert later.
What you need before you start
An available, compliant name. It has to include "LLC" or "L.L.C." and be distinguishable from every other entity already registered with the Secretary of State. Search the state's business name database before you file anything.
A registered agent with a physical Washington street address. PO boxes and private mailboxes don't qualify, and the agent has to be available during normal business hours to accept service of process.
Names and addresses for your organizer and any members or managers.
A plan for the Business License trigger conditions. You'll find out during filing whether your LLC needs a Washington State Business License; it's worth checking the trigger list (below) before you start so it doesn't catch you off guard.
The 9 steps to start a Washington LLC
These nine steps run in order, start to finish.
1. Search and reserve your LLC name
Check name availability through the Secretary of State's business name search before you file anything. Your name has to include "LLC" or "L.L.C." and can't be confusingly similar to another entity already on file.
If you're not ready to file yet but want to lock in a name, Washington lets you reserve one for $30. That reservation holds for 180 days and can't be renewed, so time it close to when you'll file.
2. Appoint a registered agent
Every Washington LLC needs a registered agent with a physical street address in the state, available during normal business hours. If you or a co-founder has a Washington address, you can serve as your own registered agent at no cost.
Otherwise, commercial registered agent services are widely available, with pricing that varies by provider.
3. File your Certificate of Formation
This is the document that creates your LLC, governed by RCW 25.15. The filing fee is $180, whether you file online or by mail, plus a small additional processing fee on top for online filings that the state doesn't publish as a fixed figure.
If you need it faster than standard processing, Washington offers two paid tiers: expedited service for $100 per entity, generally turned around within 3 business days, or same-day service for $150.
4. File your Initial Report
Washington requires an Initial Report within 120 days of formation. File it at the same time as your Certificate of Formation and there's no extra charge; a checkbox on the online form lets you defer it, but if you file it separately later, it costs $10.
Filing it alongside your Certificate of Formation is the simpler path and skips a second deadline to track.
5. Apply for your Washington State Business License
This step trips people up because it runs through a different agency than the one you just filed with. The Secretary of State forms your entity. The Department of Revenue issues the business license that lets you operate.
You need this license if any of the following apply:
You're operating under a name other than your own legal name
You plan to hire employees within 90 days
You'll collect sales tax on what you sell
Your gross income is $12,000 a year or more
You owe the Department of Revenue any taxes or fees
You need city, county, or state endorsements to operate
If sales tax is what triggers this for you, Washington's state sales tax rate is 6.50%, and combined state-and-local rates run up to roughly 9.51% depending on where you operate.
The processing fee is $50 to open a new business location under a new UBI number, $10 for most other filing purposes, and $0 to add an additional location (endorsements carry their own separate, variable fees).
Processing takes roughly 10 business days online, longer if endorsements are required (add 2 to 3 weeks), or up to 6 weeks by mail.
6. Draft an operating agreement
Washington doesn't require you to file an operating agreement with the state. It's still the internal document that spells out ownership, profit splits, and decision-making, and skipping it is legal only on paper. A bank, an investor, or a future co-founder dispute will ask to see it anyway.
7. Get an EIN
An Employer Identification Number is free, issued by the IRS, and generally available the same day you apply online. You'll need it to open a business bank account and to file taxes.
Many banks and card platforms let you start the account-opening process while your EIN is still processing, running in parallel rather than one step blocking the next. Either way, no money moves in or out of that account, in either direction, until the EIN lands.
8. Open a business bank account
Once your EIN arrives, open a dedicated business account and route every business dollar through it. Mixing personal and business funds is one of the fastest ways to undercut the liability protection an LLC is supposed to give you.
9. File your Annual Report
Washington requires an Annual Report every year, due by the last day of the month your LLC was originally formed. It costs $70, and you can file it up to 180 days ahead of the deadline.
Miss it and Washington adds a $95 delinquency fee. Keep missing it, and the state can administratively dissolve your LLC.
What a Washington LLC actually costs in year one
The breakdown below covers more than just the headline filing fee.
Item | Year-one cost |
|---|---|
Certificate of Formation (state filing) | $180 |
Online processing fee | Small additional fee, not published by the state |
Initial Report | $0 if filed with your Certificate of Formation ($10 if filed later) |
Washington State Business License | $50 (new UBI location) |
Registered agent | Free if you serve as your own; commercial services vary by provider |
EIN | $0 (IRS, always free) |
Total (DIY, self as registered agent) | Around $230, plus a small online processing fee |
Search results and some "cheapest state" roundups quote Washington's $180 filing fee as the whole story. That's the Secretary of State's number alone.
It leaves out the Business License almost every operating LLC needs. A realistic year-one budget for a business that will hire, collect sales tax, or clear $12,000 in gross income lands closer to $230.

Going it alone versus paying someone else to handle the filing comes with a real tradeoff.
What it costs to form the same LLC through a formation service instead
DIY | Formation service | Rho | |
|---|---|---|---|
Starting cost | $180 (state fee only) | Many start at $0 plus state fees, with paid tiers adding registered agent service, an operating agreement template, and expedited filing | N/A |
What's included | Just the filing; you handle everything else | Varies by provider and tier | N/A |
State fees included? | You pay them directly | Usually passed through separately | N/A |
Handles Washington LLCs? | Yes | Yes, a mainstream state for most national formation services | No |
To be direct about that last column: Rho Incorporation files Delaware C corporations only. LLC support, in Washington or any other state, isn't available yet.
Common mistakes to avoid when forming a Washington LLC
Assuming "no income tax" means no state tax. Washington doesn't tax personal or corporate income, but its Business and Occupation tax applies to gross revenue regardless of profit. Budget for it before assuming Washington is automatically cheaper than a state with a small income tax.
Skipping the Business License. The Certificate of Formation only covers your Secretary of State registration. If your LLC meets any of Washington's trigger conditions, you still need a Business License through the Department of Revenue to be fully set up.
Using a PO box for your registered agent address. Washington requires a physical street address; PO boxes and private mailboxes aren't accepted, and using one can get your filing rejected.
Reserving a name too early. A name reservation expires after 180 days and can't be renewed. Time it close to your actual filing date instead of locking it in months ahead.
Letting the Annual Report lapse. Miss the deadline and Washington adds a $95 delinquency fee. Keep missing it, and the state can administratively dissolve your LLC, which then costs $140 plus every missed report to reinstate.
Washington LLC compliance checklist: what to track after you file
Two dates matter most going forward:
Annual Report: $70, due by the last day of the month you originally formed. File up to 180 days early.
Business License renewal: If your license carries a state or city endorsement, it renews annually for a $5 fee plus the endorsement fee. A late renewal adds a penalty of half the endorsement fee, up to $150.
Beyond the deadlines, run it like a real business: keep your finances separate, sign contracts in the LLC's name rather than your own, and keep your registered agent and business license current rather than letting either lapse quietly.

FAQs
Budget around $230 for year one once you count the $180 Certificate of Formation, the Washington State Business License (starting at $50), and a small online processing fee. The state filing fee alone is $180.
It's a separate registration through the Department of Revenue, on top of your Secretary of State filing. You need it if you operate under a different name than your own, plan to hire within 90 days, collect sales tax, clear $12,000 in gross income a year, owe the state taxes or fees, or need local endorsements.
No personal or corporate income tax. Washington does levy a Business and Occupation tax, a gross-receipts tax that applies to revenue regardless of profitability.
Yes. The filing itself is a straightforward online or mail submission to the Secretary of State, and nothing about the process requires a lawyer.
Washington doesn't publish a fixed turnaround for standard processing. Paid options are faster: expedited service ($100) generally turns around in 3 business days, and same-day service is available for $150.
Yes, every Washington LLC needs one. It's a person or service with a physical Washington street address, available during business hours, who can accept legal documents on your LLC's behalf.

$70 a year, due by the last day of the month your LLC was originally formed. You can file up to 180 days ahead of the deadline.
No. The $180 state filing fee always applies. "Free" formation-service offers waive that provider's own service fee, not the state's charge.
Washington adds a $95 delinquency fee. Continuing to miss it can lead to administrative dissolution, which costs $140 plus every missed report fee to reinstate.
The most common one is stopping at the Certificate of Formation and skipping the Business License that most operating LLCs still need from the Department of Revenue. Budgeting for the Business and Occupation tax up front, using a real street address for your registered agent, and keeping your Annual Report on schedule round out the list.
Washington doesn't require you to file one with the state, but it's still the document that spells out ownership and decision-making, and the one a bank or investor will likely ask to see.
Apply directly with the IRS; it's free and usually issued the same day online. You'll need it before you can open a business bank account.
No. This guide covers Washington State. Washington, D.C. is a separate jurisdiction with its own filing process and fees.
Rarely. Most VCs require a Delaware C corp structure. If fundraising is the plan, see our guide to what a C corp actually is.
The Certificate of Formation, filed with the Secretary of State, creates your LLC as a legal entity. The Business License, filed separately with the Department of Revenue, is what lets that entity actually operate, hire, or collect sales tax in Washington.
