A business name is a trading name registered with ASIC that sits on top of an existing legal entity, while a company is a separate legal entity in its own right, incorporated under the Corporations Act 2001. Most Australian sole traders and partnerships register a business name first, but choosing between the two structures has significant legal, tax, and liability implications worth understanding before you commit.
Registering a Business Name vs Company Name: Key Differences – 2026 AU Guide
Starting or restructuring a business in Australia means confronting an early and important decision: do you register a business name, or do you incorporate a company? The two options are often confused, yet they represent fundamentally different legal arrangements. This guide breaks down what each option actually is, how they differ in practice, and what questions to ask before you decide.

What Is a Business Name Registration?
A business name, sometimes called a trading name, is simply a name under which an individual, partnership, or other legal entity trades. It does not create a new legal entity. When you register a business name through the Australian Securities and Investments Commission (ASIC), you are recording that a particular ABN holder intends to trade under that name – nothing more.
For example, if you are a sole trader with the legal name Jane Smith and you want to operate as "Sunrise Design Studio," you would register that as a business name. Legally, however, you remain Jane Smith. Any contracts, debts, or legal proceedings are in your name personally. The business name is, in essence, a label attached to you or your existing structure.
Business name registrations are managed and searchable through ASIC, and details are held on the Australian Business Register (ABR -- Australian Business Register). You will need an active ABN before you can register a business name.

What Is a Company Name Registration?
Incorporating a company is an entirely different process. A company is a distinct legal entity, separate from its directors and shareholders. It is created under the Corporations Act 2001 and regulated by ASIC (ASIC).
When you register a company, you are effectively bringing a new legal "person" into existence. That entity can enter contracts, own property, employ people, sue and be sued, and accumulate debts -- all in its own name. The most common type for small and medium businesses in Australia is a proprietary limited company, often indicated by "Pty Ltd" at the end of the name.
The company name itself is reserved at the time of incorporation and becomes part of the company's legal identity. Unlike a business name, you do not need to hold a separate business name registration if you trade under your company's actual name. If you want to trade under a different name, however, you would still need to register a business name linked to the company's ABN.

Key Legal and Liability Differences
This is where the distinction matters most in practical terms.
As a sole trader with a business name, you have unlimited personal liability. If the business incurs debts or faces a legal claim, your personal assets -- your home, savings, and vehicle -- may be at risk. There is no legal separation between you and the business. As a company director, your personal liability is generally limited to the value of your shares (in a limited liability company). Creditors of the company can ordinarily only pursue the company's assets, not yours personally. There are important exceptions, including insolvent trading provisions and personal guarantees, which is why you should speak with a qualified legal professional before relying on this protection.The implications for contracts, insurance, and dispute resolution are also significant. A company enters agreements in its own name; a sole trader signs personally. This affects how counterparties perceive your business, your eligibility for certain contracts, and your exposure to risk.

Tax and Reporting Obligations
The tax treatment of each structure differs considerably, and the right choice depends on your individual circumstances. Neither structure is universally advantageous; both have trade-offs.
Sole traders (who typically hold a business name) report business income as part of their personal income tax return. The business itself does not lodge a separate tax return.
Companies, by contrast, are separate tax entities. They lodge their own tax returns and, subject to eligibility, may be taxed at the corporate tax rate rather than at personal marginal tax rates. The Australian Taxation Office provides detailed guidance on the obligations attached to each structure (Australian Taxation Office).
The reporting burden for a company is generally higher. Directors have legal duties under the Corporations Act, and companies must maintain registered records, lodge annual statements with ASIC, and meet other ongoing compliance requirements. These carry associated costs and administrative effort that sole traders with a business name are not subject to.

Costs and Ongoing Fees
Costs for both registrations are set by ASIC and are subject to change. Rather than stating a specific fee here that may become outdated, we recommend checking the current fee schedule directly at ASIC before making any decisions. Business name registrations are available for one or three years, while company registration is a single upfront incorporation fee with an annual review fee thereafter.
Beyond the government fees, factor in the potential cost of professional assistance (accountants, solicitors, or registered agents), ongoing bookkeeping, and any compliance software you might need. Companies generally carry higher ongoing professional costs than sole trader arrangements, though this varies widely based on complexity.

Which Structure Suits Your Situation?
There is no single correct answer. The right choice depends on factors including your revenue expectations, risk tolerance, growth plans, the number of people involved, and your personal financial circumstances.
A business name registration is often appropriate if you are starting out, testing a market, or operating a low-risk service as a sole trader. It is faster, simpler, and carries lower ongoing obligations. Many successful small businesses in Australia operate this way for years.
A company structure is often considered when your business involves significant contracts, employees, or assets; when you want liability separation; when investors or co-founders are involved; or when your accountant advises it suits your tax position. It signals a degree of formality and permanence that some clients and partners look for.

How to Register: A Practical Overview
For a business name, you will need an ABN first (apply via the ABR), then register the name through the ASIC Connect portal. The process is generally completed online within minutes, subject to name availability checks.
For a company, registration is also completed online through ASIC Connect or via a registered agent. You will need to prepare details including the company's proposed name, registered office address, directors, shareholders, and share structure. business.gov.au provides plain-language guidance on the incorporation process for small business owners.
In both cases, the chosen name must not be identical or deceptively similar to an existing registered name. ASIC provides a name availability search tool on its website.

FAQ
Q: Can I have both a business name and a company at the same time? A: Yes. Many business owners incorporate a company and then register a separate business name for the company to trade under. The business name is linked to the company's ABN rather than a personal ABN. Q: Does registering a business name protect that name? A: Not in the way a trademark does. Registering a business name does not give you exclusive rights to use that name across Australia. For stronger name protection, you would need to consider trade mark registration through IP Australia. Q: If I already have a business name, can I convert to a company later? A: You cannot convert a business name into a company directly -- they are different things. You would incorporate a new company and, if you wish, register the same trading name as a business name linked to the company's ABN. Speak with an accountant or solicitor about the transfer of assets and contracts involved. Q: Do I need a lawyer to register a business name or company? A: Neither registration legally requires a solicitor, and many Australians complete both processes independently online. However, for company incorporation in particular, professional guidance is advisable to ensure the structure suits your circumstances and your obligations as a director are clearly understood.---
