Company name rules: what ASIC allows when registering

The decision you are actually making

Registering a company involves two separate naming decisions that people routinely merge into one: the legal name recorded by ASIC, and the trading or brand name you use publicly. This article is about the first one. It is the name that appears on the register, next to your Australian Company Number, on invoices, contracts and company documents.

The practical consequence is that your first choice may not survive lodgement. ASIC applies acceptability rules to every proposed legal name, so the useful work happens before you submit anything: test your shortlist against those rules and against what is already registered, and pick something that will clear both.

One distinction worth holding onto early: a registered business name is not a company name, and registering one does not give you exclusive ownership of a word. It permits you to trade under that name; it does not create the separate legal entity that registration does. According to business.gov.au, registering a company creates a separate legal entity, distinct from a business name registration.

Your three options at registration

According to business.gov.au, when you register you can use a new name, your Australian Company Number (ACN), or a name that you have reserved with ASIC.

That gives you three workable paths:

• A new legal name. The standard route, subject to ASIC's acceptability rules and availability.
• Your ACN as the name. Available because you are issued an ACN when you register; ASIC manages ACNs. Some groups choose this deliberately, deferring a trading identity decision, though it changes how the company is identified day to day.
• A reserved name. Reservation holds a name while the surrounding decisions are finalised. This is the option worth considering if you are coordinating incorporation with a domain purchase, a business name registration or a transaction that depends on a specific name being available.

How ASIC tests a proposed legal name

ASIC publishes its acceptability rules at the "Rules for acceptable company names" page. Rather than paraphrasing them loosely, treat that page as the point of truth on the day you lodge, because it is where the current list of restricted words and their conditions lives. Two tests generally operate together:

Availability. business.gov.au directs applicants to check whether the wanted company name is available on ASIC's search. Do this against every name on your shortlist, not just your favourite, and record the results. Availability is narrower than most people expect — it is a question of what is already on the register, not of whether anyone is trading under something similar in your suburb.

Acceptability. A name can be unregistered and still unavailable to you, because it uses a word ASIC restricts or because it would mislead about the nature, scale or affiliations of the business. Check each meaningful word in your proposed name against the restricted words set out in ASIC's rules; assume that words suggesting government connection, professional standing, financial activities or large-scale enterprise attract scrutiny.

Restricted words and who has to consent

ASIC's rules organise restricted words into groups, and each group carries its own consent requirement. Two of those requirements are worth stating precisely, because they cannot be resolved after lodgement:

• Group 2 words require consent from the relevant minister before you apply to register your company with ASIC.
• Group 3 words require consent from the Australian Prudential Regulation Authority (APRA) before you apply to register your company with ASIC.

Read those carefully: the consent is a precondition, obtained before you lodge, not a formality to tidy up later. If your proposed name contains a word in either group, your registration timeline is governed by whoever issues that consent, not by ASIC's processing time. Confirm which group each word in your name falls in by reading ASIC's rules page directly, and build the consent step into your planning before you commit to an incorporation date.

The trust pathway

There is a specific route where a new company can take over an existing business name: according to the guidance reflected in the sources, the new company can use the business name if each trustee is going to be a company director or member (shareholder), and they have given ASIC a copy of the trust deed. Both limbs matter — the intended roles of the trustees, and the trust deed having been lodged with ASIC. If you are incorporating a corporate trustee for an existing trust, this is the condition set to check before you assume the name transfers cleanly.

Checklist before you lodge

1. Write down three acceptable legal names, in preference order, rather than one.
2. Check each name's availability on ASIC's search and keep a dated screenshot or note of each result.
3. Separate each name into its meaningful words and check every one against the restricted words on ASIC's rules page.
4. Identify which group any restricted word belongs to. If it is Group 2, you need ministerial consent first; if it is Group 3, you need APRA consent first.
5. Decide deliberately between a new name, your ACN and a reserved name, based on what the entity needs to do immediately after registration.
6. If incorporating a corporate trustee using an existing business name, confirm each trustee will be a director or member, and that ASIC holds a copy of the trust deed.
7. Check the licences and permits your activities may require. The Australian Business Licence and Information Service (ABLIS) is the service for this, reachable on 13 28 46, and ABN Lookup is available through the same service.
8. Remember that none of this resolves trade mark questions. Company registration is not trade mark protection, and a name ASIC accepts may still conflict with someone's registered trade mark.

After registration

ASIC issues your ACN when you register, and ASIC manages ACNs. You will receive an annual statement from ASIC after the annual review date, which is usually the date you registered the company. Practically, that review date becomes a recurring obligation: it recurs annually, it is tied to your registration date, and the company — not any individual — is the entity that holds it. Diarise it at incorporation rather than waiting for the first statement.

If you later want to trade under something different from the registered legal name, that is a business name decision, handled separately. ASIC's online services for business name holders cover logging in, cancelling or transferring a business name.

Questions you should verify yourself

These depend on your circumstances and can change, so confirm each one against the official source rather than against any summary, including this one.

Next steps

Work in this order. Run your shortlist through ASIC's availability search first, since that step is quick and will usually eliminate something. Take the survivors to ASIC's "Rules for acceptable company names" page and check every word against the restricted list. If one of those words sits in Group 2 or Group 3, stop and obtain the minister's or APRA's consent before you lodge — nothing downstream can substitute for it. Then decide, with that information in hand, whether a new name, your ACN or a reserved name suits what the company needs to do immediately after registration.

Keep your branding decisions separate throughout. The name that gets through ASIC is a compliance outcome; the name you take to market is a commercial one, and they only sometimes coincide.
