Many businesses trade under a name that is not their legal name, and that name has its own registration with its own renewal date. When the renewal is missed, the name can lapse while the business carries on trading under it.
This guide explains how business names relate to your ABN and company, what a lapse means, and who should be watching for it.
A business name is registered separately
A business name registration is not the same thing as an ABN or a company registration. A company or individual holds an ABN or ACN, and that entity can then register one or more business names to trade under.
This matters because:
- Registering a company does not register a business name for it.
- An active ABN does not mean the business name is current.
- A business name can be held by a different entity from the one you think you are dealing with.
When you check an ABN, the record may list business names, but the name's own registration status is a separate question.
Renewal cycles
Business names are registered for a fixed period, with a choice of one or three years when registering or renewing. When the period ends, the holder needs to renew. The register can send reminders to the contact details it holds, but those details are only as good as the last update. An old email address or an unmonitored inbox is a common reason renewals are missed.
Check the current renewal process, periods and fees on the official register rather than relying on a third party summary, because they can change.
What a lapse or cancellation means
If a name is not renewed by its expiry date, the registration can be cancelled. In general terms (check the register for any late-renewal options):
- The holder is no longer registered to carry on business under that name.
- The name may become available, so someone else may be able to register it.
- Other records, such as the ABN entry, may continue to show the old name for a time.
A lapse is usually an administrative failure, not a sign of wrongdoing. It can also be a sign that the business has wound down, so it is worth asking.
The risk of trading on a lapsed name
The most common failure mode is plain: a name expires, and invoices, signage, websites and contracts keep using it. Specific risks include:
- Invoices and contracts: documents issued under a name the holder is no longer registered to use can be questioned by customers, accountants and counterparties.
- Someone else registers it: once the name is available, another party can register it, which can mean disputes over a name the business has built goodwill around.
- Confusion about who you are dealing with: a customer or supplier may no longer be able to tell which entity stands behind the name.
- Compliance gaps: a regulated or licensed business may find its filings and public listings no longer match.
None of this is fear-mongering. It is the ordinary result of a date being missed and nobody being told.
Why professionals and landlords should watch names
If you act for other people or rely on a business name in a contract, you often cannot see the holder's renewal date.
- Accountants and advisers: a client's trading name lapsing is a quiet risk to the client and a professional embarrassment if it surfaces first through a customer complaint. See accountants.
- Commercial landlords: a lease and a tenant's public identity often rest on a trading name. If the name lapses, the tenant may be trading under a name it no longer holds. See the landlord due diligence guide.
- Franchisors: franchisees trading under a brand name or a related name need those registrations to stay current.
How to check a business name
- Search the official business names register for the name and confirm its status and expiry details.
- Confirm the holder matches the entity you expect, not just the name.
- Compare against the ABN record for the same entity.
- Note the renewal date and set your own reminder.
A quick checklist:
- Is the name current on the register?
- Is the holder the entity you contract with?
- Does the name match what appears on invoices and contracts?
- When is the next renewal due?
- Are the holder's contact details current?
