Washington filing facts
Key numbers to know before you form or maintain a Washington business entity. These are the fees and deadlines published by the Washington Secretary of State Business Search.
How much does it cost to form an LLC in Washington?
The total cost of forming a Washington LLC depends on which extras you need. Here is the full breakdown based on the current fee schedule published by the Washington Secretary of State Business Search:
| Item | Cost | Required? |
|---|---|---|
| Articles of Organization filing fee | $200 | Yes |
| Name reservation (optional) | $30 | Optional |
| Annual report / recurring fee | $0 per year | Yes (ongoing) |

| Estimated 5-year total cost | $200 | — |
Watch for the franchise tax: No franchise tax; a B&O gross receipts tax applies to most businesses. This is separate from the filing fee and catches many new owners off guard — factor it into your real first-year cost.
These figures cover the state filing fee only. If you hire a formation service or a registered agent, add their service charge on top. For a side-by-side comparison of every state, use our LLC Cost Calculator.
How Washington compares to other states
Here is where Washington stands among all 51 jurisdictions, based on the fee schedules and processing times we track:
For context, the cheapest state to form an LLC is Kentucky at $40, while the most expensive is Massachusetts at $500. Washington's $200 filing fee puts it $71 above that national average. Founders here pay a premium, so weigh the state's business climate and market access against the higher fee. Keep the recurring $0 report in mind when comparing long-term costs.
Business entity types available in Washington
Washington recognizes several business structures, with filing fees ranging from $200 for an LLC to $180 for a corporation. Choosing the right one affects your liability protection, tax treatment, and ongoing paperwork. Here are the most common options:
LLC
Limited Liability Company — the most popular choice for small businesses. Combines liability protection with flexible, pass-through taxation. Filing fee: $200.
Corporation (C-Corp)
A separate legal entity that can issue stock. Subject to corporate income tax, but ideal for raising venture capital. Filing fee: $180.
S-Corporation
A tax election (not a separate entity type) that lets profits pass through to owners, avoiding double taxation. File Form 2553 with the IRS after forming a corp or LLC.
Partnership
General and limited partnerships for two or more owners. Simpler to form but offers less liability protection than an LLC unless structured as an LP or LLP.
Sole Proprietorship
The simplest structure — no formal filing required. However, the owner is personally liable for all business debts. Best for low-risk, single-owner operations.
Foreign Entity
Already registered in another state? Register as a foreign entity in Washington for $200 to legally operate here.
How to form an LLC in Washington
Forming a Washington LLC takes a handful of steps. Most owners complete the paperwork in a single afternoon, and the state approves filings in 1-2 business days.
Choose a compliant name
Your name must be distinguishable from existing Washington entities and include a designator like "LLC" or "Limited Liability Company". Use the search tool above to check availability first.
Appoint a registered agent
Every Washington LLC needs a registered agent with a physical address in the state. You can serve as your own agent or hire a commercial service for privacy.
File the Articles of Organization
Submit the formation document to the Washington Secretary of State Business Search and pay the $200 filing fee. Most states accept online filing, which is faster than paper.
Create an operating agreement
Not always required by the state, but an operating agreement defines ownership percentages, profit splits, and management rules. Banks and investors often ask for one.
Get an EIN from the IRS
Apply for a free Employer Identification Number at IRS.gov. You'll need it to open a business bank account, hire employees, and file taxes.
Handle state & local registrations
Register for state taxes, sales tax permits, and any local business licenses your city or county requires. Requirements vary by industry and location.
Washington business tax overview
Understanding Washington's tax landscape helps you plan cash flow and choose the right entity structure. Here are the key state-level taxes that affect Washington businesses:
Note: Washington taxes business gross receipts (B&O tax) instead of income.
LLCs are typically pass-through entities, meaning profits flow to the owners' personal tax returns rather than being taxed at the entity level. However, some states impose entity-level taxes or fees regardless of structure. Always confirm current rates with the Washington Department of Revenue or a licensed tax professional before making decisions.

Renewals and ongoing compliance in Washington

Washington annual report: fee, deadline, and penalties
LLCs file an annual report (no fee) by the end of the anniversary month.
How to file: Most Washington reports can be filed online through the Washington Secretary of State Business Search. Log in, confirm your entity information is current, and pay the fee. Keep a copy of the confirmation for your records.
What happens if you miss it: If the report is not filed on time, Washington can assess the late penalty listed above and eventually administratively dissolve or revoke your LLC. A dissolved entity loses its liability protection and its legal right to do business in the state, and you will need to file a reinstatement (which costs more than simply filing on time). Set a calendar reminder a few weeks before the due date so you never miss it.
Certificate of Good Standing in Washington
A Certificate of Good Standing — also called a certificate of existence or certificate of status — is an official document from the Washington Secretary of State Business Search confirming that your business is legally registered, active, and current on its required filings. Banks, lenders, and other states treat it as proof that your entity is legitimate.
When you need one:
- Opening a business bank account or applying for a business loan.
- Registering your Washington entity as a foreign LLC in another state.
- Renewing certain professional or industry licenses.
- Closing a real estate transaction or signing a large contract where the other party verifies your status.
How to get it: Order the certificate through the Washington Secretary of State Business Search — most states let you request it online and download a PDF instantly, or mail you a certified paper copy. There is usually a small fee, and the entity must be current on its annual report (due End of anniversary month) to qualify. If your entity is not in good standing, file any overdue reports first, then request the certificate.
LLC vs. corporation in Washington
Both structures limit personal liability, but they differ in taxation, governance, and suitability. Here's a quick comparison to help you decide:
| Factor | LLC | Corporation |
|---|---|---|
| Formation fee | $200 | $180 |
| Taxation | Pass-through by default | Corporate tax (C-Corp) or pass-through (S-Corp election) |
| Governance | Flexible — operating agreement | Formal — board, officers, bylaws, annual meetings |
| Raising capital | Harder — no stock | Easier — can issue shares |
| Paperwork | Minimal | More record-keeping required |
| Best for | Small businesses, freelancers, real estate | Startups seeking investors, larger companies |
For most small-business owners in Washington, the LLC is the simpler and more tax-efficient choice. If you plan to seek venture funding or go public, a corporation (usually a Delaware C-Corp) is the standard path.
Who uses Washington business entity search?
The official Washington entity database is not just for business owners. With 7.81M residents and 92,100 new businesses formed in 2023, a wide range of professionals and everyday users rely on it:
- Entrepreneurs and founders check whether a desired business name is available before filing formation documents.
- Attorneys and paralegals verify entity status, registered agents, and good standing during transactions, litigation, and due diligence.
- Lenders and banks confirm a borrower's legal existence and status before approving business loans or lines of credit.
- Landlords and property managers verify that a prospective commercial tenant is a real, active entity before signing a lease.

What a Washington entity record shows
When you pull up a business in the Washington Secretary of State Business Search, the record typically includes the entity's legal name and any assumed names, its entity type (LLC, corporation, limited partnership, etc.), current status, formation or registration date, the name and address of the registered agent, and the principal office address. Some states also list the names of officers or members. This is the same information banks, landlords, and courts rely on when verifying a business.
Common Washington search mistakes
- Searching the exact full name only — try a partial name or drop the "LLC"/"Inc." suffix if you get zero results.
- Assuming a name is available because it isn't an exact match — the state also rejects names that are "deceptively similar" to existing entities.
- Confusing a trade name or DBA with the legal entity name — search both if the business operates under a brand name.
- Not checking the entity status — an "Active" name may belong to a dissolved or revoked entity that still blocks your filing.
Washington business name rules
Before you file, make sure your chosen name satisfies Washington's naming rules. The Washington Secretary of State Business Search will reject your filing if the name fails any of these checks:
- Distinguishable on record. Your name must be distinguishable from every existing Washington entity name. Use the search tool above to check for exact and similar matches first.
- Required designator. LLC names must include an entity designator such as "LLC", "L.L.C.", or "Limited Liability Company". Corporations must include "Inc.", "Corp.", "Corporation", or an equivalent.
- Restricted words. Words that imply a regulated profession (bank, insurance, attorney, university) or a government affiliation may require extra approvals or be prohibited outright.
- Name reservation available. Name reservation fee is $30 and holds the name for 180 days. Reservation costs $30 and is useful when you found a good name but are not ready to file yet.
How to reserve a business name in Washington
Name reservation fee is $30 and holds the name for 180 days.
How it works: First confirm the name is available using the search tool at the top of this page. Then file a name reservation application with the Washington Secretary of State Business Search and pay the fee. The state holds the name for you so no one else can register it while you finish preparing your formation documents. When you are ready, file your Articles of Organization and use the reserved name.
Reservation is optional — if you plan to file right away, you can skip it and just form the LLC. It is most useful when you found a great name but need a few weeks to sort out your operating agreement, EIN, or funding.
Registered agent requirement in Washington
Every Washington LLC and corporation must maintain a registered agent — a person or company with a physical street address in Washington who is available during normal business hours to receive legal documents (service of process) and official state mail on behalf of the business. You can act as your own registered agent if you live in the state, but many owners use a commercial registered agent service so their home address stays off the public record and they never miss a legal delivery. The registered agent's name and address appear in the public entity record, which is one reason privacy-conscious owners hire a service.
