A Washington Name Change Touches Two Agencies

Documents and supporting paperwork for an articles of amendment filing.

Washington splits business administration between two agencies, and a name change is the filing where that split becomes expensive. The Corporations and Charities Division of the Washington Secretary of State holds the entity record: the articles, the name, the registered agent, the governance provisions. The Department of Revenue, through the Business Licensing Service, holds the Unified Business Identifier account, the state business licence, the endorsements a business needs to operate, and any registered trade name. Amended Articles filed with the Secretary of State do not update anything held by Revenue.

That means a Washington rebrand is two projects, not one. Amended Articles cost $30 at sos.wa.gov and change the legal name on the entity record. The business licence and any trade names have to be updated separately through the Business Licensing Service, and a licence in the old name will not support a bank account opened in the new one. Washington LLC amendments run under the Washington Limited Liability Company Act at RCW § 25.15, and the current form is on the Washington articles of amendment page.

What belongs on the Amended Articles

Entity name, registered agent and registered office, the shift between member managed and manager managed, stated purpose, duration, and for a corporation the authorised share provisions. Endorsements, licence categories, and trading names do not belong here. Neither does the officer information a corporation reports on its annual report.

Approve it and record the vote

Member or manager approval is required before the articles are signed. The operating agreement sets the threshold and RCW 25.15 supplies the default where it is silent. The Division does not verify the vote, so the written consent exists for the members and for whoever reads the file during a sale or a financing. Date it ahead of the filing and keep it with the operating agreement.

Clear the name in both systems

Check the proposed name against the Corporations and Charities index and against registered trade names, because a name free at the Secretary of State may already be in use as a trade name through the Business Licensing Service. Run a Washington business search first, and use a name reservation where the launch date is fixed.

File, then update the licence

The Amended Articles need the exact current name, the UBI number, the article being amended with its replacement text, the adoption date, and an authorised signature. File at sos.wa.gov with the $30 fee, add $50 where two business days matter. Then, and this is the step Washington filers most often miss, lodge a business licence application update with the Business Licensing Service so the licence, the endorsements, and any trade name carry the new legal name.

While you are here

File an amendment

If you would rather not do this yourself, we draft the articles of amendment and file them with the right agency the first time. Or keep reading and file it on your own. This guide covers everything you need either way.

The $10 Agent Filing

Moving the registered agent or the registered office does not require Amended Articles. Washington takes a Statement of Change of Registered Agent at $10 against a $30 amendment, a two thirds saving on the change entities make most often. The agent must maintain a Washington street address and consent to serve under RCW § 23.95.420, which is what forces the filing when a provider changes or when a member acting as agent leaves the state.

Use Amended Articles only when the articles themselves are changing. Where an agent move happens in the same month as a name change, put both on one $30 document rather than paying $40 across two. A portfolio owner switching agent provider across ten Washington entities pays $100 with the right form and $300 with the wrong one. Requirements sit on the Washington registered agent page.

The Risk Sitting Behind a Stale Washington Record

Washington charges $60 for the annual report, due at the end of the anniversary month, with a $25 penalty for late filing. That is the visible cost. The bigger exposure comes from the two agency structure, because an entity can be perfectly current with one and in default with the other without anyone noticing.

Work through a rebrand that stops at the Secretary of State. The entity record says one name; the business licence and endorsements say another. Revenue assesses excise tax against the UBI account tied to the licence, and remittances made under a name that does not match create reconciliation problems that take weeks to resolve. Cities that piggyback local licensing on the state licence issue permits in the old name. A bank asked to open an account in the new name wants the licence and the articles to agree, and will decline while they do not. Meanwhile a stale registered agent address means the $60 annual report notice never arrives, $25 in penalties attach, and continued default leads to administrative dissolution, at which point the entity cannot obtain a certificate of existence. Our Washington reinstatement guide covers the repair, and the Washington annual report guide covers the calendar that prevents it.

Against all of that, the arithmetic is $30 for the amendment, $10 for an agent change, and an hour spent on the licence update. The cost of skipping any of the three is measured in weeks rather than dollars.

Three Washington Amendments in Practice

The three below are composites drawn from filings of this type. The Washington figures are real; the business facts are illustrative.

Scenario one: a Seattle sole member rebrand

A single member design studio trading under the founder name wanted a studio identity before signing a retainer with a large client. Action taken: name checked against the entity index and against registered trade names, sole member consent signed, Amended Articles filed at standard speed, then a business licence update lodged with the Business Licensing Service the day the articles posted. Cost: $30 at the Secretary of State. Timeline: nine business days for the articles, a further week for the licence to reissue. Outcome: the client contract, the licence, and the bank account all carried the same name. Doing the licence update first would have failed, because the licence follows the legal name rather than leading it.

Scenario two: a corporation restating its articles

A Tacoma manufacturing corporation with four shareholders had amended its articles three times over twelve years and no single document showed the current position. Action taken: board adoption, shareholder vote recorded in the minute book, and a single restatement filed as Amended Articles consolidating every prior change and adding a new share class. Cost: $30 plus $50 expedited, because an investor closing was eight days out. Timeline: two business days at the Division. Outcome: one clean document that the investor counsel could read without assembling a chain of prior amendments, which removed the diligence question that had been holding the closing.

Scenario three: a Washington LLC registered in Oregon and Idaho

A regional installer formed in Washington also held registrations in Oregon and Idaho. Action taken: Amended Articles in Washington first at $30, a certificate of existence ordered once they posted, the Washington business licence updated with Revenue, then amended registrations in Oregon and Idaho with the certificate attached. Timeline: about seven weeks across three states and two Washington agencies. Outcome: five consistent records. The sequence matters: the home state amendment has to come first, and the certificate the other states want cannot be issued until it has. The Washington foreign qualification page sets out the neighbouring requirements.

Five Mistakes That Stall Washington Amendments

Mistake 1: Stopping at the Secretary of State

What it is: filing Amended Articles for a name change and leaving the business licence untouched. Why it happens: the articles feel like the authoritative record, and they are, but only for the entity. Consequence: the licence, the endorsements, and any trade name stay in the old name, excise remittances mismatch, cities issue permits to a name that no longer exists, and banks decline the account. Prevention: treat the Business Licensing Service update as part of the same job and lodge it the week the articles post.

Mistake 2: Updating the licence first

What it is: applying to change the licence name before the articles are amended. Why it happens: the licence is the document the business interacts with daily. Consequence: the application does not match the entity record and is refused, and the sequence has to be restarted. Prevention: amend the articles, wait for the stamped copy, then update the licence.

Mistake 3: Paying $30 for a $10 change

What it is: filing Amended Articles to move a registered agent. Why it happens: the amendment is the better known document. Consequence: $20 wasted per entity, which becomes real money across a portfolio. Prevention: where the agent or the agent address is the only change, file the $10 Statement of Change.

Mistake 4: A name free at one agency and taken at the other

What it is: clearing a name against the entity index alone. Why it happens: trade names live in a different system run by Revenue. Consequence: an entity name that clears, followed by a trade name application that does not, and a brand that cannot be used as intended. Prevention: check both systems before drafting. Our Washington trade name guide explains how the two interact.

Mistake 5: Leaving the agent address behind after a move

What it is: relocating and not filing the $10 change. Why it happens: nothing prompts it until something goes wrong. Consequence: the $60 annual report notice and any service of process go to an address nobody reads, $25 in penalties attach, and administrative dissolution follows. Prevention: file the statement in the week the lease changes, and lodge IRS Form 8822-B within 60 days where the responsible party or business address moved.

How File.Business Handles a Washington Amendment

We pull the live Corporations and Charities record and the Business Licensing Service record together, because in Washington the two disagree more often than either one is wrong on its own. We decide whether the change belongs on Amended Articles or on a $10 Statement of Change, draft the document, clear the name against both the entity index and registered trade names, prepare the member or manager consent, and file at sos.wa.gov with the $30 fee. We then sequence the licence update with Revenue so the endorsements and any trade name follow the new legal name. The stamped articles reach your document vault with a downstream checklist covering the licence, banking, IRS Form 8822-B, insurance, city permits, and registrations in other states, and the anniversary month report date goes into our compliance suite.

Washington amendment FAQ

How much does it cost to amend articles in Washington?

Amended Articles cost $30 at the Washington Secretary of State. Expedited two business day handling adds $50. A registered agent change on its own is a $10 Statement of Change. See our amendment service for what is included.

How long does a Washington amendment take?

Standard processing at the Corporations and Charities Division runs 5 to 10 business days. The $50 expedite fee returns the stamped articles in about 2 business days, which is worth paying when a financing or a licence application is waiting.

Does a Washington amendment update my business licence?

No. The Secretary of State holds the entity record and the Department of Revenue holds the business licence, the endorsements, and any registered trade name through the Business Licensing Service. A name change requires both a filing with the Secretary of State and a separate licence update with Revenue.

Which comes first, the articles or the licence?

The articles. The business licence follows the legal name on the entity record, so a licence name change applied for before the Amended Articles are accepted will be refused. File the articles, wait for the stamped copy, then lodge the licence update.

Do I need an amendment to change my Washington registered agent?

No. A Statement of Change of Registered Agent costs $10 against $30 for Amended Articles. Use the amendment only when the articles themselves are changing, or when an agent move can travel on the same document as another change.

What happens if a Washington record is left wrong?

The $60 annual report notice goes to the agent on file, so a stale address means a missed report, a $25 penalty, and eventually administrative dissolution. Separately, a licence in a superseded name causes excise reconciliation problems with Revenue and blocks bank account changes.

Can File.Business handle my Washington amendment?

Yes. We reconcile both the entity record and the licensing record, choose between the $30 Amended Articles and the $10 Statement of Change, clear the name in both systems, file with the Secretary of State, and sequence the Department of Revenue licence update afterwards.
