State facts
Washington Corporation
Formation Basics
These are the questions people ask before they've filed anything — the "how does this even work" tier.
Who can form a Washington corporation?
Almost anyone. There's no residency or citizenship requirement for incorporators, shareholders, directors, or officers. A single adult can form a corporation, be its only shareholder, serve as the entire board, and hold every officer position. The one in-state requirement is a Washington registered agent with a physical street address.
What document creates the corporation?
The Articles of Incorporation, filed with the Secretary of State's Corporations and Charities Division through the CCFS portal. It's a short public filing that records the corporate name, authorized shares, registered agent, and basic addresses. It does not disclose your shareholders, your finances, or your business plan.
How is a corporation different from an LLC?
A corporation is owned by shareholders, governed by a board of directors, run by officers, and its internal rules live in corporate bylaws. An LLC is owned by members and governed by an operating agreement. Corporations are the default for raising venture capital and issuing stock options; LLCs offer simpler, more flexible governance. Both are formed through CCFS and both provide liability protection when run properly.
Filings and Deadlines
Once the corporation exists, staying compliant is mostly about hitting a few recurring dates.
What is the Initial Report?
Washington requires a newly formed corporation to file an Initial Report within 120 days of formation. It confirms your governing people and addresses on the record. Many filers submit it alongside the Articles of Incorporation so it's handled from day one.
What is the annual report?
Every active Washington corporation files an annual report through CCFS by the anniversary of its formation each year. It updates your registered agent, addresses, and governing people. It's not a financial statement — you're not reporting revenue or profit. Letting it lapse eventually leads the state to administratively dissolve the corporation.
What happens if I miss a filing?
Missing the annual report puts the corporation out of good standing, and continued non-compliance leads to administrative dissolution. A dissolved corporation loses the legal protections that made incorporating worthwhile, though Washington generally allows reinstatement by catching up on the missed filings and fees. It's far cheaper to file on time than to reinstate.
Taxes and Money
Washington's tax setup surprises people, so this section is worth reading carefully.
Does Washington have a corporate income tax?
No. Washington has neither a corporate nor a personal income tax. Instead it imposes the Business and Occupation (B&O) tax on gross receipts, administered by the Department of Revenue separately from your Secretary of State filings. Because it's based on revenue rather than profit, the B&O tax can apply even in a year the corporation loses money.
Do I have to register with the Department of Revenue?
Generally yes. Active businesses register with the Washington Department of Revenue for a business license and B&O tax account. The state ties this to your UBI number so the agencies recognize the same corporation. Depending on your activity and city, you may also need local endorsements or industry licenses.
What's a UBI number?
The Unified Business Identifier is a nine-digit number Washington assigns when your corporation is approved. It links your Secretary of State, Department of Revenue, and Employment Security records under one identifier that you'll use across state agencies.
Structure and Governance
These questions come up once the corporation is real and you're setting it up internally.
Do I need a board of directors if it's just me?
Yes, but the board can be one person — you. Washington allows a single-director board. You'll elect that director (yourself) at the organizational meeting, appoint yourself to the officer roles, and document it in your records. The structure exists even in a one-person company; it just doesn't require additional people.
Do I have to file my bylaws with the state?
No. Corporate bylaws are internal and never filed with Washington. You adopt them at the organizational meeting and keep them in your corporate records. Only the Articles, the Initial Report, and annual reports go to the state.
What are authorized shares?
Authorized shares are the maximum number of shares the corporation may issue, set in the Articles of Incorporation. It's a ceiling, not an obligation — you can authorize a large number and issue only a fraction to founders, holding the rest for future investors or employees.
Registered Agent and Foreign Corporations
The last cluster of common questions concerns agents and out-of-state companies.
Can I be my own registered agent?
Yes, if you have a physical Washington street address and are available there during business hours. The tradeoff is that the address appears in the public CCFS record. Many owners use a commercial agent to keep a home address private and guarantee someone is always available to accept service of process.
My corporation is from another state — can it operate in Washington?
Yes, but it usually has to foreign qualify first: register with the Secretary of State for a Certificate of Authority and appoint a Washington registered agent. Operating without qualifying can bar you from Washington courts and expose you to back fees and penalties. See our foreign registration page for the full process.
Can Mainstay Filing handle all of this?
We prepare and file your Articles of Incorporation, include registered agent service, flag your Initial Report and annual report deadlines, and handle foreign qualification for out-of-state corporations. We're a filing service, not a law or accounting firm, so legal structuring and tax strategy stay with your attorney or CPA.
Frequently asked questions
How much does it cost to incorporate in Washington?
The Secretary of State charges a filing fee for the Articles of Incorporation, and there's a recurring annual report fee to keep the corporation in good standing. Online filing is cheaper than paper. Our costs page and the receipt on our formation pages break down exactly what's state fee versus service, with no hidden line items.
How long does it take to form a Washington corporation?
Online filings through CCFS are typically processed within a few business days. Paper filings by mail take substantially longer, and expedited service is available for an added fee. The corporation is legally active once the state approves the Articles and issues your confirmation and UBI number.
Do I need a lawyer to incorporate in Washington?
No. Incorporating is a procedural filing you can complete yourself or through a filing service like ours. A lawyer becomes valuable when you have multiple founders splitting equity, outside investors, complex stock arrangements, or industry-specific regulatory questions. For a straightforward formation, the filing itself doesn't require one.
Can a single person own a whole Washington corporation?
Yes. One individual can be the sole shareholder, the only director, and hold every officer role. Washington allows a single-director board, so a true one-person corporation is entirely valid. You'll still adopt bylaws, hold an organizational meeting, and keep records — the formalities apply regardless of headcount.
What ongoing filings does a Washington corporation have?
The main recurring state filing is the annual report through CCFS, due by the anniversary of formation. Separately, you file B&O tax returns with the Department of Revenue on the schedule it assigns. You also maintain a valid registered agent and keep up internal formalities like annual meetings and minutes.
What if I stop using my corporation — do I still have to file?
Yes, until you formally dissolve it. An inactive corporation that skips its annual report or B&O filings accrues compliance problems and eventually gets administratively dissolved by the state, which can leave loose ends. If you're done with the corporation, dissolve it properly rather than letting it lapse. Our dissolution page covers the steps.
