Can you change a company name after registration?
Yes. A company can change its name at any time by passing a special resolution of its members (shareholders). A special resolution requires at least 75% of the votes cast by members entitled to vote on the resolution. The resolution can be passed at a general meeting, or in a proprietary company by a circulating resolution signed by every member entitled to vote (or recorded and signed by the sole member).
Before changing the name, you should check that the proposed new name is available using ASIC’s name availability search. The name must not be identical to an existing company name or registered business name (unless held by the same entity). Certain words require ministerial consent or may be restricted.
Once the special resolution is passed, the company must lodge the change of name notification (Form 205) with a copy of the resolution and the ASIC fee within 14 days, or a late fee applies. The new name takes effect when ASIC updates the company’s registration, and ASIC will issue an updated Certificate of Registration showing the new name. The company must then update all public-facing documents, signage, and contracts to reflect the new name.
A name change does not affect the company’s ACN, ABN, or legal obligations. Contracts entered into under the old name remain valid. However, the company should notify its bank, insurance providers, and other counterparties of the change. If the company is registered for GST, the ATO record will be updated automatically through the ABR.
CoSec Partners handles name change applications including the special resolution, Form 205 lodgement, updated certificate of registration, and an updated company register reflecting the new name.
Frequently asked questions
Does changing a company name change its ACN or ABN?
No. The ACN is issued once at registration and stays with the company for life. The ABN is also unchanged; the ABR record is updated to show the new name. Because the identifiers persist, existing contracts, leases, and registrations remain valid under the new name.
How long does an ASIC company name change take?
Once the special resolution is passed and the Form 205 is lodged (within 14 days, or a late fee applies), ASIC generally processes the change within a few business days and issues an updated certificate of registration. The practical work that follows, such as updating signage, banking, insurance, and counterparties, usually takes longer than the lodgement itself.
Can I use a business name instead of changing the company name?
Often, yes. Registering a business name lets the company trade under a different name without altering its legal name, which is cheaper and faster. A formal name change is the right answer when the legal identity itself needs to change, for example after a rebrand, a sale, or a group restructure.
