The core facts: Changing your LLC name requires filing Articles of Amendment (called Certificate of Amendment in some states) with the Secretary of State where your LLC was formed. State filing fees range from $20 to $150. Online filings are approved in 1 to 10 business days; paper filings take 2 to 6 weeks. No new EIN is required. The IRS processes mailed name-change notifications in approximately six weeks. The FinCEN BOI report must be updated within 30 days if your LLC is subject to reporting requirements. Contracts signed under the old name remain valid — the legal entity does not change, only its name does.

Quick Answer

To change your LLC name, file Articles of Amendment with your state Secretary of State (fee: $10 to $150), update your EIN records with the IRS, notify your bank, licenses, contracts, and domain registrars. Most states process in 1 to 3 weeks. Costs $50 to $300 all-in depending on state.

Last verified: April 2026. State filing fee data confirmed from Secretary of State sources. IRS notification guidance from IRS.gov/businesses/business-name-change.

Your LLC can have only one legal name, and that name is fixed in the Articles of Organization filed with your state when the LLC was formed. Using a different name informally — on invoices, websites, or business cards — does not legally change the name. Only a state filing does that.

The good news: changing an LLC name is one of the more straightforward state filings. It does not change the legal entity, does not require a new EIN, does not affect your tax elections or liability protections, and does not void existing contracts. What it does require is a specific sequence of steps — state filing first, then IRS notification, then a list of downstream updates that most guides handle too briefly. This guide covers all of it, including the one update most people miss: the FinCEN BOI report, which must be updated within 30 days under the Corporate Transparency Act if your LLC is subject to its requirements.

First: Legal Name Change vs. DBA — Which Do You Actually Need?

Before filing anything, answer this question honestly: do you need your LLC's legal name to change, or do you just want to operate under a different brand name?

These are different things with different costs, timelines, and downstream implications:

Factor Legal Name Change (Articles of Amendment) DBA / Fictitious Name
What it changes Official name in all state records, federal records, contracts, licenses, bank accounts Adds a trade name; legal name stays the same on all official records
Cost $20 to $150 state filing fee $10 to $100, simpler form
Member approval required Usually yes (per operating agreement) Usually no
IRS notification Required Not required
Bank account update Required Not usually required
License and permit updates Required for all licenses Usually not required
Downstream work Significant: IRS, state tax, bank, licenses, contracts, FinCEN Minimal: file DBA, update customer-facing materials
Multiple brand names One legal name only — each rebrand requires another amendment Multiple DBAs allowed simultaneously
Best for Trademark conflicts, complete rebrands, entity name causing legal problems Testing a new brand, running multiple brands, marketing name different from legal name
The DBA option is faster and cheaper — but does not solve all problems. If your current LLC name infringes on someone else's trademark, a DBA using that same name still infringes — you need to either change the name entirely or choose a non-infringing DBA. If lenders, government agencies, or major clients require your legal name to match your brand name, a DBA does not solve that either. But for most branding situations — wanting a customer-facing name different from the legal entity name — a DBA is the right tool.

Common Reasons LLCs Change Their Names

Understanding why you are changing your name helps clarify which approach to take and what additional steps may be involved:

  • Trademark conflict discovered: You formed your LLC with a name that overlaps with an existing registered trademark. The trademark owner sent a cease-and-desist. A legal name change is required — a DBA using the same name does not resolve the infringement.
  • Geographic limitation in the original name: "Denver Plumbing Services LLC" expanded to five states. The name now limits customer perception of the business's service area. A legal name change removes the geographic constraint.
  • Business pivot or rebrand: The LLC's business model shifted significantly. "Smith Photography LLC" now runs an event management company. Continuing under the original name creates confusion with customers and suppliers.
  • Merger, acquisition, or partner change: New partners joined or the company merged with another entity, and the name needs to reflect the new ownership or combined brand.
  • Name was poorly chosen at formation: Common with startups that used a placeholder name at formation and never updated it. The legal name now appears on everything — bank accounts, contracts, licenses — and a professional rebrand requires the legal name to match.
  • Eliminating a personal name from the business: "John Smith Consulting LLC" wants to create separation between the founder's personal identity and the business for succession planning or sale purposes.

Step-by-Step: How to Change Your LLC Name

1

Search name availability in your state's business registry

Your proposed new name must be distinguishable from all other entities already registered in your state. Most states offer a free online business entity search on the Secretary of State's website. Search your exact proposed name and close variations. "Distinguishable" means the state's registry system identifies it as sufficiently different — not just a capitalization change, punctuation swap, or addition of "The" or "and." Many states apply a phonetic distinctiveness test: a name that sounds the same as an existing registration will be rejected even if spelled differently.

A state business registry search is not a trademark search. A name can be available in your state's registry but still infringe on a federally registered trademark. Conduct both searches separately.

2

Search the USPTO trademark database for federal conflicts

Go to USPTO.gov and search the Trademark Electronic Search System (TESS) for your proposed name. Look for active registered trademarks in your industry category (NICE classification classes). A name that is available in your state's business registry can still infringe on a federally registered trademark — and a trademark owner can sue for infringement even if you completed the state filing. This search adds 15 to 30 minutes but can save significant legal exposure. If your search reveals a potential conflict, consult a trademark attorney before filing anything with the state.

3

Reserve your new name (optional but recommended)

Most states allow you to reserve your chosen name for 30 to 120 days for a small fee (typically $10 to $50). Name reservation prevents another entity from registering your chosen name while you prepare the amendment filing. This is most useful if you are coordinating the name change with a marketing launch, a partner agreement, or other timing-sensitive events. If your state's turnaround time is short (1 to 3 days for online filings), a reservation may not be necessary. But if you are filing by mail in a state with multi-week processing times, a reservation provides protection during the wait.

4

Get member approval per your operating agreement

For multi-member LLCs, your operating agreement specifies the voting threshold required for name changes. Common thresholds: majority vote (more than 50%), supermajority (two-thirds or 75%), or unanimous consent. Review your operating agreement's amendment provisions specifically — name changes are sometimes treated as "major" changes requiring a higher threshold than ordinary business decisions. Document the approval in written resolutions or signed consent forms. These become part of the LLC's permanent records and may be required by the state with the amendment filing. For single-member LLCs, no vote is required — the sole member can authorize the change unilaterally.

5

Complete the Articles of Amendment (Certificate of Amendment) form

Locate your state's amendment form on the Secretary of State's website. The form goes by different names in different states: Articles of Amendment, Certificate of Amendment, Statement of Amendment. Most states use a single unified form for all LLC amendments; some have separate forms for name changes only. The form typically requires: your LLC's current legal name (exactly as it appears in state records — check the registry for the precise spelling, capitalization, and punctuation); your state-assigned LLC file number or entity ID (found on your original Articles of Organization); the proposed new name; the effective date (same as filing date, or a future date in states that allow delayed effectiveness); and the signature of an authorized member or manager.

The most common rejection cause: the current LLC name on the amendment form does not exactly match the name on file with the state. Verify the precise name — including punctuation and capitalization — in the Secretary of State's database before completing the form.

6

File and pay the state fee

Submit the completed form to your state's Secretary of State (or equivalent agency) with the filing fee. Most states accept online filing through their business portal; some require mail-in submissions. Fees range from $20 (Mississippi, Wyoming biennial) to $150 (Texas, Pennsylvania). Online filing is typically faster and provides immediate confirmation of receipt. Expedited processing is available in most states for an additional fee — typically $25 to $200 for 24-hour processing, and $75 to $500 for same-day processing in states that offer it. New York offers 24-hour expedited processing for $25, same-day for $75, and 2-hour processing for $150 (plus the $60 base fee).

7

Receive and store your Certificate of Amendment

After approval, the state returns a filed, stamped copy of your amendment — often called a Certificate of Amendment or a file-stamped copy. This document is your official proof that the name change is legally effective as of the effective date stated on the form. Keep the original in your LLC's permanent records. Request certified copies if you need them for bank account updates or other institutions — many banks and government agencies require certified copies rather than simple photocopies. The fee for certified copies is typically $5 to $30 per copy depending on the state.

How to Notify the IRS After Your Name Change

Changing your LLC name does not require a new EIN. The IRS treats the name change as a modification to the same legal entity — the EIN stays. But the IRS must be notified so its records match your state filing. The method of notification depends on how your LLC is taxed:

LLC Tax Classification How to Notify the IRS When to Do It
Single-member LLC (Schedule C, disregarded entity) Send a signed letter to the IRS at the address where you file your return, stating your old LLC name, new LLC name, and EIN. Or note the name change on the Schedule C filed with your next Form 1040. Within 60 days of state approval, or on next tax filing
Multi-member LLC (Form 1065 partnership return) Check the "Name Change" box on Form 1065 when filing the annual partnership return. Or send a signed letter to the IRS address where you file. On next annual filing (Form 1065 due March 15) or by letter sooner
LLC taxed as S-Corporation (Form 1120-S) Check the "Name Change" box on Form 1120-S when filing the annual S-Corp return. Or send a signed letter to the IRS. On next annual filing (Form 1120-S due March 15) or by letter sooner
LLC taxed as C-Corporation (Form 1120) Check the "Name Change" box on Form 1120 when filing. Or send a signed letter to the IRS. On next annual filing (Form 1120 due April 15) or by letter sooner
IRS processing timeline: The IRS typically processes mailed name-change notifications in approximately six weeks. During this period, you can continue operating under your new name — the state approval is what makes the name legally effective, not the IRS update. If you need confirmation from the IRS before the six-week period (for a banking relationship or license update that requires IRS acknowledgment), request a written acknowledgment in your initial notification letter. The IRS will send a written confirmation to your address of record. Note that Form 8822-B is for reporting changes in business address or responsible party — it is not the form for a name change. Do not use Form 8822-B for this purpose.

In addition to the IRS, notify your state's Department of Revenue or Taxation of the name change. Provide the amended state registration document. State tax account updates typically happen within a few weeks; some states update automatically when you file your next state tax return under the new name.

Everything to Update After State Approval

The state filing is one step. The downstream work — updating every system, account, and document that references your LLC's name — takes most of the time. Organize updates by urgency:

FinCEN BOI Report (within 30 days) If your LLC is subject to Corporate Transparency Act BOI reporting, file an updated report at boiefiling.fincen.gov within 30 days of the name change becoming effective. Late updates: civil penalties up to $500/day. Verify current BOI reporting status at fincen.gov — domestic US entities were granted exemptions in 2025.
Business bank accounts Bring your Certificate of Amendment (certified copy) to your bank. Update the account name on checking, savings, and merchant processing accounts. Order new checks and deposit slips. Update ACH payment instructions sent to vendors and clients.
Foreign state registrations If your LLC is foreign-qualified in other states, file an amended certificate of authority in each state. Home state amendment must be complete first. Each foreign state has its own form and fee ($50 to $300 per state).
IRS notification Notify the IRS using the method appropriate for your tax classification (see table above). No new EIN required. Processing takes approximately six weeks by mail.
Business licenses and permits Contact each issuing agency to update your license to the new name. Professional licenses may require board approval or re-application. City and county business licenses require updated registration. Some licenses must be surrendered and reissued under the new name.
State tax accounts Update with your state Department of Revenue: income tax account, sales tax permit, payroll tax registrations, unemployment insurance account. Provide a copy of the Certificate of Amendment with your request.
Operating agreement Amend your LLC operating agreement to reflect the new name. This is an internal document — no state filing required for the amendment itself. All members should sign the amended or restated agreement. Keep the executed amendment with the original operating agreement.
Insurance policies Notify your general liability, professional liability, property, workers' compensation, and umbrella insurers. Request updated certificates of insurance reflecting the new LLC name. Insurance coverage continues without interruption — this is a name update, not a new policy.
Contracts and vendor agreements Notify counterparties of the name change. For ongoing contracts, add a simple written amendment or letter documenting that the legal entity operating under the new name is the same entity that signed the original agreement. Existing contracts remain valid.
Registered agent records If you use a professional registered agent, notify them of the name change. They update their records to ensure compliance notices and legal documents are matched to the correct entity. Northwest Registered Agent ($125/year) updates records automatically upon receipt of the filed amendment and handles registered agent service in all 50 states — useful if you need to update registrations in multiple states.
Digital presence Update your website (domain if applicable, business name in site content and metadata), email signatures, social media profiles and bios, Google Business Profile, Yelp and directory listings, LinkedIn company page, and any e-commerce storefronts (Amazon, Etsy, Shopify, etc.).
Physical materials Update: business cards, letterhead, envelopes, signage, vehicle wraps, product packaging, brochures, and any other physical materials that display your LLC name. Budget time and money for these updates when planning your name change timeline.
The update people most often forget: the FinCEN BOI report. Under the Corporate Transparency Act, many LLCs must file Beneficial Ownership Information with FinCEN and update that report within 30 days whenever reported information changes. An LLC name change is a reportable change. Missing this 30-day window triggers civil penalties of up to $500 per day, plus potential criminal penalties for willful non-compliance. File at boiefiling.fincen.gov. Note: as of March 2025, domestic US entities were granted exemptions from BOI requirements following court challenges to the Corporate Transparency Act — verify current status at fincen.gov before assuming you must file.

Multi-State LLCs: Amendment in Each Qualified State

If your LLC is foreign-qualified (registered to do business) in states beyond its home state, a name change in the home state does not automatically update the registration in those other states. You must file amended registrations in each state where you are foreign-qualified.

The required sequence: Complete and receive approval of the home-state Articles of Amendment first. Then use the approved, filed amendment document (and usually a new Certificate of Good Standing from the home state) to file amended certificates of authority in each foreign state. Most states call this an "Application for Amended Certificate of Authority" or "Amendment to Foreign LLC Registration." Each state has its own form, fee, and processing timeline. Some states require the amendment within a specific number of days after the home state approval — timelines vary from 30 to 90 days depending on the state.

Typical foreign state amendment costs: Filing fees range from $25 (Mississippi) to $300 (Connecticut, some others) per state. An LLC foreign-qualified in five additional states might pay $200 to $700 in amendment fees across those states, plus whatever each state's processing time requires.

Practical tip for multi-state amendments: Order multiple certified copies of your home state Certificate of Amendment — typically $5 to $30 each — at the time you receive the approved document. Many foreign states require a certified copy (not a photocopy) of the home state amendment as part of the foreign state amendment filing. Having 5 to 7 certified copies in hand from the start eliminates back-and-forth with your home state Secretary of State while you are processing each foreign state filing.

State-Specific Requirements: NY, CA, TX, FL

New York: publication requirement and paper-only for most amendments

New York requires all LLCs (domestic and foreign) to publish a notice in two local newspapers when they amend their Articles of Organization in ways that include a name change. The publication must run in the county where the LLC's principal office is located. Cost varies by county: Manhattan and Brooklyn counties can run $500 to $1,000+; upstate counties typically cost $75 to $400. After publication runs for six consecutive weeks, you file a Certificate of Publication with the Department of State ($50 fee). Online filing for name-only amendments is now permitted; all other amendments are still paper only. Base filing fee: $60.

California: straightforward but watch for Statement of Information

California LLC name changes use BizFile Online and are processed in 3 to 5 business days. Base filing fee: $30. Within 90 days of the amendment effective date, confirm that your Statement of Information (filed biennially) reflects the new name — if your next biennial Statement is due before you would naturally update it, filing an updated Statement proactively avoids having the name mismatch in public records. California's $800 annual franchise tax continues uninterrupted; no new payment is required for the name change itself.

Texas: most expensive amendment fee; county clerk filings for some counties

Texas uses Form 424 (Certificate of Amendment) submitted through SOSDirect. Filing fee: $150 — one of the highest in the country for a simple name change. Some counties in Texas require additional filings with the county clerk for DBAs or assumed names. If your LLC currently operates under an assumed name in Texas, the assumed name registration must also be updated to reflect the new legal entity name. Texas processes online amendments in 5 to 7 business days; expedited options are available.

Florida: cheapest common state, tight filing accuracy requirement

Florida uses the Sunbiz portal and charges just $25 for an LLC amendment — the lowest among large states. Processing typically takes 3 to 5 business days online. One specific Florida requirement: the amendment form must include your LLC's document number (the Florida entity ID assigned at formation) exactly as it appears in the Sunbiz database. Errors in the document number are the most common rejection cause for Florida amendments. Look up your document number in Sunbiz before completing the form.

Common Mistakes That Cause Rejections and Delays

Most amendment rejections are preventable. These are the specific failure modes that cause the most filings to be returned:

  • Current name does not exactly match state records. The amendment form requires your LLC's current legal name precisely as it appears in the state's business registry — including spelling, capitalization, punctuation, and spacing. "Smith & Jones LLC" is different from "Smith and Jones LLC." "Smith Jones L.L.C." is different from "Smith Jones LLC." Verify the exact name in the registry before completing the form.
  • Missing entity ID / file number. Most states require your LLC's state-assigned file number or entity number on the amendment form. This is not your EIN — it is the number the state assigned when your Articles of Organization were filed. Find it on your original formation documents or in the state's business registry under your LLC's listing.
  • New name not sufficiently distinguishable. The proposed new name conflicts with an existing registered entity. Always search the registry before filing — a rejected amendment typically does not receive a refund of the filing fee in most states.
  • Wrong form used. Some states have separate forms for name changes versus other amendments, for registered agent changes, and for principal office changes. Using the wrong form results in rejection. Confirm you are using the current version of the correct form for your amendment type.
  • Missing or unauthorized signature. The amendment must be signed by a member or manager who is authorized to act on behalf of the LLC. Some states specify that it must be a "manager" for manager-managed LLCs. Verify the signatory requirement for your LLC type in your state.
  • Assuming a DBA updates the legal name. Filing a DBA after getting rejected on the trademark front does not change the LLC's legal name. If the problem is the legal entity name — not just the operating name — a full amendment is required.

Frequently Asked Questions

Can I change my LLC name to something similar to a competitor's name?

Not if the competitor has a registered trademark on that name or a substantially similar name. A state business registry search only confirms availability within that state's filings — it does not tell you whether the name conflicts with federal trademarks. Before choosing your new name, search the USPTO trademark database at USPTO.gov/trademarks/search. If a competitor holds a live federal trademark in your industry category, using a similar name — even if it clears the state registry — exposes you to an infringement lawsuit regardless of where your LLC is formed. When in doubt, consult a trademark attorney before filing.

How long does the entire name change process take?

State approval is the fastest part: 1 to 10 business days for online filings in most states (up to 6 weeks for paper-only states like Wyoming). IRS notification processing: approximately 6 weeks by mail. Bank account updates: typically 1 to 5 business days. License updates: varies by agency and license type, but plan 2 to 8 weeks for professional licenses. BOI report update: file within 30 days of state approval. Full completion of all downstream updates — licenses, foreign states, bank accounts, contracts, digital presence — realistically takes 4 to 8 weeks from state filing to having everything consistent. Plan at least 6 to 8 weeks for the complete process, especially if your LLC is registered in multiple states.

Do my customers need to sign new contracts after my LLC name changes?

No. Existing contracts remain valid because the legal entity that signed them has not changed — only its name has. Courts treat the LLC after a name change as the same entity that executed the original contract. However, sending counterparties a brief written notice of the name change (with a copy of your Certificate of Amendment) is good practice. It eliminates confusion about which entity is a party to the contract, prevents payment mismatches (if a client issues a check to the old name), and creates a clear record that the counterparty was notified. For ongoing contracts, a simple letter or email from your LLC stating the name change effective date and the new legal name is sufficient.

Can I change my LLC name and EIN at the same time?

A simple name change does not require a new EIN, and you should not obtain a new EIN just because you changed your name. The IRS assigns EINs to legal entities, not to names. The EIN stays with the entity. New EINs are required only when the legal entity itself changes — converting from an LLC to a corporation, creating a new LLC through dissolution of the old one, or certain ownership restructurings. If you are unsure whether your specific situation requires a new EIN, see IRS Publication 1635 "Understanding Your EIN" or call the IRS Business & Specialty Tax Line at 1-800-829-4933.

What if I want to change my LLC name in one state but keep the old name in other states where I'm registered?

An LLC has only one legal name. Once you change the name in your home state, that becomes the legal name of the entity everywhere. You cannot maintain different legal names in different states. If you need different brand names in different markets, the solution is DBAs registered in each state — one DBA with one brand name in one market, another DBA with another brand name in a different market, all under the same legal LLC name. This is a common and legitimate structure for businesses operating multiple brands across different geographic markets.

Can I pick an LLC name that ends in "Inc." or "Corp." instead of "LLC"?

No. LLC names must include an LLC designator: "Limited Liability Company," "LLC," or "L.L.C." Using corporate designators like "Inc.," "Corp.," "Incorporated," or "Corporation" is not permitted for an LLC — those terms are reserved for corporations. If you want your business to carry a corporate name, you would need to convert the LLC to a corporation, which is a different and more complex process than a name change. Some states allow LLCs to use "Co." or "Company" without an LLC designator if no incorporation-related terms are included, but rules vary by state.
