Delaware LLC Amendment: 2026 Guide

What is a Delaware LLC amendment?

A Delaware LLC amendment is a filing that changes the public record held by the state — specifically, something written in your Certificate of Formation. When you formed the LLC, Delaware accepted a short document listing the company name and the registered agent and registered office in Delaware. An amendment is how you change one of those items after the fact. The instrument you file is called a Certificate of Amendment, authorized under the Delaware Limited Liability Company Act.

The single most important thing to understand up front is the difference between the public certificate and your internal records. The Certificate of Formation is the thin public filing. Your operating agreement is the private contract among the members that governs ownership, profit splits, management, and how decisions are made. Many things owners assume require a state amendment actually live only in the operating agreement, so they are changed internally with no state filing at all.

What changes actually require a Delaware amendment?

Because a Delaware LLC certificate contains so little, very few changes require a state amendment. The name change is the main one. Almost everything else owners want to update is either a separate dedicated filing or a purely internal record change.

This is the edge case that catches most people: Delaware LLCs do not name their members or managers on the public certificate, so you never file a state amendment to change who owns or runs the company. That is handled entirely inside your operating agreement. If you came from a state that does list members publicly, this will feel unfamiliar, but it is one of the reasons Delaware appeals to non-resident owners who value privacy.

How do you file a Delaware LLC name change amendment?

The name change is the most common amendment, so it is worth walking through in order. The Certificate of Amendment itself is short, but the sequence matters because a single mismatch causes a rejection.

• Check the new name is available. Delaware will reject a name that is not distinguishable from an existing Delaware entity. Run a name search before you draft anything, and confirm the required designator (LLC, L.L.C., or Limited Liability Company) is present.
• State the exact current name. The amendment must recite your existing LLC name precisely as it appears on the original certificate, then state the new name. A typo in the current name is a common reason for rejection.
• Get an authorized signature. An authorized person of the LLC signs. For a single-member non-resident LLC that is simply the owner, signed electronically.
• File and pay. Submit to the Delaware Division of Corporations with the $200 fee, choosing an expedited tier if you are on a deadline.

Once Delaware accepts it, you receive a stamped Certificate of Amendment. That document is your proof of the new name, and you will need it repeatedly: the IRS, your bank, Stripe, and any contracting counterparty will ask to see it.

How much does a Delaware LLC amendment cost?

The Delaware state fee to file a Certificate of Amendment for an LLC is $200. That is the core cost. If you need it processed faster than the standard queue, Delaware sells expedited tiers — same day, 24-hour, and one-hour — each at an additional state charge. Any preparation or filing-service fee is separate and quoted up front, so you always see the full number before anything is filed.

Crucially, an amendment is a one-time event, not a recurring cost. It does not raise or change your Delaware franchise tax, which for an LLC is a flat $300 a year regardless of name, members, or revenue. The authorized-shares and assumed-par-value calculation methods you may have read about apply only to Delaware corporations, never to LLCs, so an amendment never pushes you into a higher tax bracket. For the full picture, see our Delaware LLC cost breakdown.

How long does a Delaware amendment take?

Delaware processes a Certificate of Amendment in a window similar to a new formation. Standard handling runs a few business days depending on the Division of Corporations' current queue, and the expedited tiers compress that to same-day, 24-hour, or one-hour turnaround for an extra fee. There is no separate waiting period built into the law — the time is purely how long the state takes to review and stamp the document.

If you have an external deadline — a bank that needs the new name before opening an account, or a contract that must be signed under the new entity name — choose an expedited tier rather than hoping the standard queue moves quickly. We track the filing with the state and forward the stamped certificate the moment it is accepted, so you are not refreshing a status page yourself.

What does a real Delaware LLC name change look like?

Picture a non-resident founder who formed a Delaware LLC last year under a placeholder name while she finalized her brand. The trademark search comes back clean on the brand she actually wants, so she decides to rename the company. The first move is a Delaware name availability check on the new name; it is distinguishable from every existing entity, so she is clear to proceed. She does not touch her members or her operating agreement — only the name on the public certificate is changing.

The Certificate of Amendment is drafted reciting the exact current LLC name, then stating the new name, and she signs it electronically as the sole authorized person. It is filed with the Delaware Division of Corporations with the $200 fee, on an expedited tier because her bank will not update the account name without the stamped certificate and she has a supplier contract waiting. Delaware returns the accepted, stamped amendment, and from that moment the entity is legally renamed. Her EIN is untouched, her franchise tax is still the flat $300 due next June 1, and her Form 5472 obligation is unchanged. The remaining work is purely downstream: notify the IRS of the new name, send the stamped certificate to the bank and to Stripe, and update the LLC name on her invoices and contracts. Total cost was the $200 state fee plus the expedited charge — a one-time event, not a recurring one.

What happens to your EIN, bank, and Stripe after a name change?

A name change does not change your EIN. The IRS keeps the federal tax ID tied to the entity, not the name, so you never reapply for a new number — a relief, given that an EIN for a non-resident takes two to four weeks the first time. What you do need to do is notify the IRS of the new name so its records match the stamped certificate.

Downstream, the new name has to propagate to every account that carries the old one. Your bank — and remember that Mercury, Relay, and Wise are fintech platforms operating on FDIC-insured partner banks, not chartered banks themselves — will ask for the stamped Certificate of Amendment before updating the account name. The same is true for your Stripe account; updating the legal name is the provider's process, and they decide what documentation they need. Plan for a short period where the entity is legally renamed at the state but the accounts still show the old name until each provider catches up.

Does an amendment change your federal filing duties?

An amendment to the certificate does not, on its own, change your federal tax filing obligations. If you are a foreign owner of a single-member Delaware LLC, you still file Form 5472 together with a pro forma Form 1120 each year — the penalty for missing it is $25,000 under IRC 6038A, due April 15 (or with a Form 7004 extension). A name change does not pause or reset that duty. If anything, keep your filings consistent: the name on Form 5472 should match the amended certificate once the change is effective.

The same logic applies to how the US taxes a non-resident owner. The US reaches a non-resident only on income that is effectively connected to a US trade or business, plus US-source FDAP income taxed at a default 30% that a tax treaty in force can reduce. None of that turns on the LLC's name, so an amendment leaves your tax exposure untouched. For the broader picture, see our Delaware LLC taxes overview, and confirm specifics with a CPA who handles non-resident owners.

What are the most common amendment mistakes?

Amendments rarely go wrong at the concept stage — they go wrong on details that cause the state to reject the filing or that leave records out of sync afterward. These are the recurring ones.

• Filing an amendment for something that is not on the certificate. Trying to amend the certificate to change members or your address wastes a filing — those are internal or handled by a different form. Confirm the item is actually on your Certificate of Formation first.
• Choosing a name that is not distinguishable. The most frequent name-change rejection. Run a Delaware name availability check before you draft the amendment, and include the LLC designator.
• Misstating the exact current name. The amendment must recite the existing name precisely. A small discrepancy — a missing comma or the wrong designator format — stalls the filing.
• Forgetting the registered-agent change is a separate form. Switching agents is its own filing, not an amendment. Bundling it into a name-change amendment is a common error.
• Not updating downstream records. After the state accepts the new name, owners forget to notify the IRS and update the bank, Stripe, and contracts. The legal change is only half the job.

Every one of these is avoidable with a check beforehand. We confirm the change actually belongs on the certificate, run the name check, recite the current name exactly, and hand you the stamped copy plus a short list of who to notify afterward.

Amendment, restatement, or a separate filing — which do you need?

When owners say they want to "amend" the LLC, they usually mean one of three different actions. Picking the right one saves a wasted state fee.

A restatement is worth considering once your certificate has been amended more than once. Instead of a stack of separate amendments that a counterparty has to read together, a Restated Certificate produces a single clean document that already reflects every change — easier to certify and easier to hand to a bank or investor. For owners who expect to raise money later, that tidy public record matters; if a conversion to a C-Corp is on the horizon, a clean entity history is one less thing to untangle.

A note on BOI / FinCEN reporting

Beneficial ownership reporting changed significantly in 2025. A FinCEN interim final rule issued in March 2025 removed BOI reporting obligations for US-formed domestic reporting companies. Under that rule, only certain foreign reporting companies remain in scope, and US-formed entities and US persons are generally exempt. Filing an amendment does not, by itself, create a reporting obligation.

Because this area is still evolving and could shift again, treat no summary as final. Confirm the current FinCEN requirements at the source or with a professional before relying on your status. We monitor changes and flag them, but the duty to file if required ultimately rests with the owner. Whether you are forming, renaming, or restating, you can start the whole process remotely from anywhere in the world.
