Do I need a new EIN if I change my company's name?

No. According to the IRS, LLCs and corporations don't need a new EIN when they change their name or location. You do need to tell the IRS about the change, and update your bank and other records. A change in structure, such as forming a new corporation, can be different.

Do I have to file anything with the state to change my operating agreement?

Often not. An LLC operating agreement is usually an internal document, so updating it may not need a state filing. But if the change also affects something in your filed articles, such as the company name or, in some states, who manages the LLC, an amendment may be required.

How do I add a member to my LLC?

Usually you update the operating agreement and ownership records, with the approval it requires. Some states also want a filing or an updated annual report. Adding a member can change how the LLC is taxed, for example from a disregarded entity to a partnership, so speak with a qualified tax professional first.

How long does an amendment take?

It depends on the state. Each state sets its own processing times, and they change with workload. We don't promise a fixed turnaround, and any timing we mention is an estimate based on the state's own processing.

What does an amendment cost?

There are two parts: the state filing fee, which is paid by you and shown separately (see state fees), and Firmlane's fee for preparing and submitting the filing, shown in our catalog. Both appear separately before you pay. If you cancel before we file, see our refund policy.

How do I change my registered agent or registered office?

Most states use a dedicated statement or certificate of change rather than a full amendment, and a state fee may apply. Some states require the new agent's consent before you file. See registered agent for how the role works.

Amend your LLC or corporation the right way

Companies change: a new name, a new address, new members or managers, more shares. Some changes need a filing with the state; others only need your internal documents updated. Firmlane prepares and files amendments with your state, confirms which filing your change needs, and shows the Firmlane fee and the state fee separately before you pay.

The paperwork

Articles of amendment and certificates of amendment

Your company was created by a document filed with the state: articles of organization for an LLC, or articles or a certificate of incorporation for a corporation. To change something that document says, you file an amendment to it.

The name depends on the state. Delaware's Division of Corporations says the most common way to amend entity documents is to file a certificate of amendment. Many other states call it articles of amendment. Some also accept restated articles, which combine the original document and all amendments into one clean version.

Not every change goes through an amendment. Registered agent changes usually have their own form, and many states collect updated addresses and management details through the annual report instead. Internal documents, such as an LLC operating agreement or corporate bylaws, may not need any state filing at all, but they still need to be properly approved and signed.

Amendments change what your filed formation document says
Registered agent changes often use a separate form
Internal agreements may change without a state filing
A state filing fee applies to most amendment filings

Follow-up

After the filing

The follow-up updates people forget

The IRS
Form 8822-B reports a new mailing address, business location or responsible party. Changes in responsible party must be reported within 60 days.
Your EIN stays the same
Per the IRS, LLCs and corporations don't need a new EIN just because they change their name or location. You still need to tell the IRS about the change.
Banks and processors
Update your business profile and be ready to share the filed amendment as proof.
Other states
If you are registered to do business in other states, those registrations may need updating too.
Contracts and invoices
Make sure your legal name and address match on agreements, invoices and your website.
Internal records
Keep signed consents, resolutions and the updated operating agreement or bylaws with your records.

Ownership changes can change how you're taxed

Adding or removing owners isn't only a paperwork change. For example, an LLC taxed by default as a single-member disregarded entity is generally taxed as a partnership once it has two or more members, which brings different federal filings. Talk to a qualified tax professional before you change ownership. See bookkeeping and tax.
