How to Amend Your LLC or Corporation in Texas (2026 Guide)
The complete 2026 guide to filing an amendment in Texas: $150 state fee, the Certificate of Amendment, 3-7 business days processing, common amendment triggers, and how File.Business handles the entire filing + downstream updates.
What an Texas Certificate of Amendment Actually Changes
A Texas Certificate of Amendment is the formal filing used to change information on an LLC's or corporation's formation document after the entity has been formed. Common amendment triggers: changing the entity name; changing the registered agent name or address; changing the principal business address; changing from member-managed to manager-managed (or vice versa); adding or removing management provisions; changing the duration of the entity; and updating any other element of the formation document on the public record.
Texas amendments at $150 with $25 expedite, moderately priced for a major formation state. This is one of the distinguishing features of Texas's amendment process. The Certificate of Amendment is filed with the Texas Secretary of State through sos.state.tx.us at $150, processed in 3-7 business days standard turnaround. In Texas, amendments must be filed as a separate document, the annual report cannot be used to make formation-document changes.
When you need an amendment vs an annual report
Many states allow informational changes (registered agent, principal address) to flow through the annual report rather than requiring a separate amendment. Texas's rule: all formation-document changes require the Certificate of Amendment regardless of type. Structural changes (entity name, management type, member admission/removal) always require an amendment.
Why the amendment matters for downstream operations
A name change that's not properly amended creates problems immediately: banks reject deposits made to the new name, contracts signed under the new name may be challenged, the EIN-on-file at the IRS doesn't match, the registered agent address mismatch can trigger administrative actions. The amendment establishes the official, public record. Bank, customer, and counterparty paperwork can then be updated using the date-stamped Certificate of Amendment as proof of the change.
How to File a Texas Certificate of Amendment (Step-by-Step)

The Texas amendment process is six discrete steps. Following the order below prevents the most common rejection causes (name conflicts, missing approval, mismatched signers).
Step 1: Confirm member or manager approval
Before filing, the amendment must be approved by the LLC's members (or managers in a manager-managed LLC) per the Operating Agreement. If the OA is silent on amendment thresholds, Texas's default rule applies, typically requiring majority approval of members based on capital interest. Document the approval in writing (resolution or written consent) and keep it in the entity's records.
Step 2: For name changes, verify the new name is available
If the amendment is a name change, search the Texas business name database to confirm the proposed new name is available and not deceptively similar to an existing registered entity. Texas's name uniqueness rules are stricter than they look on paper, even minor variations can conflict. Run the search before drafting the amendment.
Step 3: Draft the Certificate of Amendment
The Texas Certificate of Amendment requires: the LLC's current legal name (exactly as on the public record); the state file number; the specific provisions being amended (with the old text and the new text); the effective date of the amendment; and the signature of an authorized member or manager. Save a copy of the draft for the entity's records before submitting.
Step 4: File through sos.state.tx.us
Submit the completed Certificate of Amendment along with the $150 state filing fee. Expedited processing is available for $25 with 1-2 business days turnaround.
Step 5: Update banking, contracts, and IRS records
For name changes, after the Certificate of Amendment is approved: provide the date-stamped amendment to your bank to update the account name; update vendor and customer paperwork; file IRS Form 8822-B if the principal business address or responsible party changed; update insurance policies; update domain registrations and online accounts; update DBA filings where applicable.
Step 6: Document in entity records
Store the approved Certificate of Amendment in the entity's document vault alongside the original formation document. Future filings will need to reference the most recent amendment. Lenders, acquirers, and counterparties will request the full amendment history during due diligence, having it organized saves significant time later.
Common Texas Amendment Mistakes
Four mistakes consistently cause delays or rejections for Texas amendments.
Mistake 1: Filing the amendment without member approval
The Texas Secretary of State doesn't verify member approval, but the amendment can be challenged later by a non-approving member if approval is required by the Operating Agreement or by Texas default rule. The challenge can unwind the change. Always document approval before filing.
Mistake 2: Name conflicts on name-change amendments
Texas's name database is strict, "Acme Holdings LLC" and "Acme Holding LLC" may collide. Run a thorough name availability search BEFORE submitting the amendment. A rejection on name grounds resets the timeline and any related downstream updates (banking, contracts) get delayed.
Mistake 3: Mismatched current entity name
The current entity name on the amendment must EXACTLY match the Texas record, including punctuation, capitalization, and designator. Any variation causes rejection. Pull the current state record before drafting the amendment.
Mistake 4: Forgetting downstream updates
The amendment changes the public record but doesn't automatically update your bank, your insurance, your contracts, your IRS records, your domain registrations, or your DBA filings. Each of those is a separate update using the date-stamped Certificate of Amendment as evidence. Build a checklist of downstream updates before filing the amendment.
How File.Business Handles Texas Amendments
File.Business runs Texas amendments end-to-end. We draft the Certificate of Amendment based on your proposed change, validate the current entity name against the Texas public record, run a name availability search for name changes, prepare a board/member resolution for approval, file through sos.state.tx.us, pay the $150 state fee, deliver the approved amendment to your document vault, and provide a downstream-update checklist (banking, IRS Form 8822-B, insurance, contracts, DBAs) so the change propagates correctly. For multi-entity portfolios making the same change across several entities, we coordinate the filings as a single engagement.
When to use File.Business for Texas amendments
Self-filing a simple address change costs only the $150 state fee, many founders handle that alone. File.Business is most valuable for: (1) name changes, where conflict checks and downstream banking updates matter; (2) multi-entity changes across several state registrations simultaneously; (3) M&A-adjacent amendments where the timing has to line up with closing; (4) any amendment where the current state record has drifted from the founders' understanding and reconciliation is needed before filing.
