To change a corporation’s name, you file an amendment to its articles of incorporation with the Secretary of State in the state where it was formed, after getting the required board and shareholder approvals. Once the state approves the amendment, the work shifts to updating the new name everywhere the old one appears: the IRS, other states where the corporation is registered, trademark records, banks, licensing agencies, and contracts. The filing itself is usually quick. The downstream updates are where corporations lose track.
Do You Actually Need a Legal Name Change?
If you want to market a new product line, run a division under a different brand, or just use a catchier name publicly, a DBA (also called a trade name, assumed name, or fictitious business name) may be enough. A DBA lets the corporation operate under a different name without touching the articles of incorporation. It’s cheaper and simpler.
A DBA does not change the corporation’s legal identity. The articles of incorporation, tax returns, and contracts still carry the original name. A DBA also gives you no trademark protection and does not stop another business from using the same name. If you need the new name on legal documents and tax filings as the corporation’s actual name, you need the full amendment process.
Clearing the New Name
State Availability
Every state requires that a corporate name be distinguishable from other business names already on file with its Secretary of State. Search the business entity database on the Secretary of State’s website for the state of incorporation before you commit. Most states offer a free online search tool. If your proposed name is too close to one already registered, the state will reject the amendment.
“Distinguishable” is a stricter standard than it sounds. Minor variations like punctuation, abbreviations, or swapping “Inc.” for “Corp.” usually will not clear the test. Pick something clearly distinct.
Federal Trademark Clearance
State availability and trademark clearance are separate questions, and skipping the trademark step is one of the more expensive mistakes a corporation can make. A name can be free on your state’s registry and still infringe a federally registered trademark. If that happens, the trademark owner can force you to stop using the name after you have already paid for new signage, documents, and marketing.
Search the USPTO’s free Trademark Search system at tmsearch.uspto.gov before finalizing. A live registration or pending application covering a similar name for related goods or services is a serious barrier. Even dead registrations can cause problems if the owner still uses the mark in commerce and holds common law rights.
Board and Shareholder Approval
Because a name change amends the articles of incorporation, it needs formal corporate approval. The board of directors must pass a resolution adopting the new name. In most states, a shareholder vote is also required, usually a majority of outstanding voting shares, though your articles or bylaws may set a different threshold.
Many states carve out a narrow exception for purely cosmetic changes, like swapping “Corporation” for “Inc.” or “Co.” for “Company,” which the board can often approve alone. For any substantive change, plan on both board and shareholder approval.
Document whatever you do. Keep a written consent signed by directors and shareholders, or formal meeting minutes recording the vote, in your corporate records. Some states ask you to reference the approval method and date on the amendment filing, and your bank or the IRS may later ask for a copy of the resolution.
Filing the Articles of Amendment
The document that formally changes the name is usually called the Articles of Amendment, though some states call it a Certificate of Amendment. Most Secretary of State offices provide a downloadable form or an online portal.
Every state’s form asks for roughly the same information: the corporation’s current legal name exactly as filed, the entity number the state assigned at formation, the proposed new name, a statement confirming that the amendment was approved by the board and, if required, by shareholders, with the approval date, and the signature of an authorized officer or director.
Most states accept filings online, by mail, or in person. Online filing is faster and often gives immediate confirmation. Fees generally run from about $25 to $150, with some states charging more, and expedited processing costs extra where it’s offered. Standard turnaround ranges from a few business days for online filings to several weeks for mailed paper. Once the state approves the amendment, you’ll receive a file-stamped copy or a certificate confirming the change. Keep it; you’ll need it repeatedly.
Notifying the IRS
How you tell the IRS depends on timing. If you haven’t yet filed your annual income tax return for the year, check the name change box on your return. For a C corporation, that’s Form 1120, Page 1, Line E, Box 3. For an S corporation, it’s Form 1120-S, Page 1, Line H, Box 2.1Internal Revenue Service. Business Name Change
If you’ve already filed for the year, send a written notification signed by a corporate officer to the IRS address where the corporation files its returns.1Internal Revenue Service. Business Name Change
A name change by itself does not require a new EIN. Your existing EIN stays with the corporation. You would only need a new EIN if the name change accompanies a structural change, like merging into a new corporation, converting to a different entity type, or getting a new charter from the state.2Internal Revenue Service.

Updating Foreign Qualifications in Other States
If your corporation is foreign-qualified to do business in states beyond its state of incorporation, you’ll need to file an amendment or updated application in each of those states. This step gets forgotten often, especially by corporations registered in several jurisdictions. Each state has its own form and fee.
One trap worth planning around: your new name may already be taken in another state where you’re registered. When that happens, the corporation usually has to adopt an alternate name, sometimes called a fictitious or assumed name, for use in that state only. Some states handle this on the amendment form; others require a separate filing. Budget extra time and fees if you operate in many states.
Updating Trademarks and Other IP
Federally registered trademarks list the corporation as owner under its legal name, so after a name change you need to update ownership records at the USPTO through the Assignment Center. You submit a cover sheet and documents showing the name change. The USPTO typically processes these in about seven days.3United States Patent and Trademark Office. Trademark Assignments: Transferring Ownership or Changing Your Name The recording fee is $40 per trademark.4United States Patent and Trademark Office. USPTO Fee Schedule
After the assignment is recorded, check the USPTO trademark database to confirm the new name appears. If the database hasn’t updated and the trademark is still in the application stage, you may need to submit a voluntary amendment or a response to the examining attorney to correct the records.3United States Patent and Trademark Office. Trademark Assignments: Transferring Ownership or Changing Your Name
Patents, copyrights, and domain registrations should be updated the same way. Domain registrar WHOIS records in particular can create confusion when the registrant name no longer matches the corporation’s legal name.
Banks, Tax Accounts, Licenses, and Contracts
Report the name change to your state’s department of revenue and any local tax authority where you file. Most states handle this through a dedicated form or an online business portal. Don’t miss your state unemployment insurance account, usually administered by the state labor or workforce agency; it’s tied to the corporation’s legal name and updates separately from income tax registration.
Contact every bank, lender, and financial institution holding corporate accounts. You’ll typically need to provide the filed articles of amendment and a board resolution authorizing the change. Expect to update account names, order new checks, and reissue debit or credit cards. If the corporation has outstanding loans or lines of credit, the lender may amend those agreements to reflect the new name.
Notify any federal, state, or local agency that issued the corporation a professional license, business permit, or registration. That includes industry-specific regulators, local business license offices, and agencies like the SEC if the corporation files public reports. Some agencies reissue the license under the new name; others simply update their records.
Existing contracts remain valid. The corporation is the same legal entity with the same EIN, rights, and obligations. Still, letting contracts drift under the old name creates practical headaches, so notify the other party and, where you can, execute a short amendment or acknowledgment updating the name. Then work outward: website, email, letterhead, invoices, business cards, insurance carriers, customers, vendors, and any industry directory or trade organization that lists the corporation. The goal is simple. When someone searches for the corporation under its new name, they should find it.
