Set up a private company: steps to register a Pty Ltd

How to register a proprietary limited company in Australia, from checking your name to getting an ABN and ACN through the Business Registration Service.

Checked: 2026-09-30

Registering a Pty Ltd is really one decision with two moving parts: you choose a company as your business structure, and then you put that company on the Australian companies register. The Australian Government's guidance is direct about the second part — if you choose a company as your business structure, you must register it on the Australian companies register, which is managed by ASIC. In practice you start that process through the Business Registration Service (BRS), and ASIC then processes the registration.

This guide walks through the order that works: settle the structure question, choose and check the name, collect the details the form asks for, lodge through the BRS, then handle licences and ongoing updates. Where a rule is a legal requirement rather than a process step, this article points you to ASIC instead of restating it, because those details need to be read from the current source.

What you are actually setting up

A proprietary limited company is a separate legal entity from the people who own and run it. That separation is the reason many founders choose it: the company contracts, holds assets and takes on obligations in its own right.

ASIC's registration pages separate company applications by type. One category is a private or public company that is unlimited — described as a company where the liability of shareholders is unlimited — and ASIC notes you need to apply for that type specifically. The ordinary Pty Ltd is the structure most small businesses register, and the difference between these types turns on how shareholder liability is treated. Treat that as the practical distinction and confirm the detail on ASIC's register-a-company page before you commit, since the choice is difficult and sometimes costly to unwind later.

Two consequences follow from registering a company rather than trading as a sole trader:

Choose the name, and understand what it is not

ASIC's register-a-company service covers registering your company, applying for a company name and getting an ACN. The company name is the legal name of the entity — it ends in "Pty Ltd" for a proprietary limited company.

That is different from a business name, which is the trading name the public sees. The government's own example makes the distinction cleanly: the company "Oranges Fruit Store Pty Ltd" might register the business name "Oranges Fruit Store". If you intend to trade under something shorter or different from the legal name, you are dealing with two registrations, not one.

Identifier What it is Where it comes from
Company name The legal name of the entity, registered with the company ASIC, via the BRS
ACN The number identifying the company on the Australian companies register ASIC, on registration
ABN The business number used for tax and invoicing Australian Business Register; new businesses can register through the BRS
Business name A trading name, if you trade as something other than the company name Registered separately

Availability is the usual sticking point. Have two or three name options ready rather than one, and check availability through the official channels rather than assuming a domain name or social handle means the name is free.

Prepare the details before you open the form

Registration is a form-filling exercise, and most of the time goes into having the correct information on hand. Expect to provide details such as the proposed company name, addresses for the company, and personal details for each director and shareholder, plus the share structure.

The exact fields, and who is eligible to be a director or shareholder, are set by ASIC and the BRS — read them from the current form instead of relying on any checklist, including this one. Questions worth verifying directly with ASIC before you apply include director residency and age requirements, whether a company secretary is required, and whether anyone involved is disqualified from managing a company. These are legal requirements, and they are the kind of thing that should be confirmed against the source on the day you lodge.

Lodge through the Business Registration Service

The Business Registration Service at register.business.gov.au is the Australian Government service that "combines a number of key government business and tax registration forms in one place". That matters practically: instead of registering the company and separately chasing an ABN, you can work through the combined flow. ASIC then processes the company registration.

In order:

  1. Go to the Business Registration Service and start the company registration.
  2. Apply for the company name you have checked, with alternates ready.
  3. Complete the associated tax registrations in the same flow, including the ABN if you are a new business. ASIC's partner guidance for new businesses points to registering for an ABN through this service.
  4. Submit, and keep the confirmation and issued ACN somewhere you will find them again.

Once registered, the company exists on the Australian companies register with its own ACN. Record that number — it goes on invoices, contracts, stationery and your accounting records.

Check licences and permits separately

Registration is not permission to trade. Whether you need a licence depends on the industry and the activity, not on your structure. The Australian Business Licence & Information Service (ABLIS) exists to identify which licences and permits apply to a given business activity, and is the right place to check before you start trading.

If the business will provide financial services, that is a separate regime again. ASIC publishes information and steps on how to apply for an Australian financial services (AFS) licence. Do not assume company registration covers it.

After registration: the register has to stay current

ASIC's guidance includes keeping company details up to date on the Australian companies register. That is an ongoing obligation, not a one-off. Changes to directors, addresses, shareholdings or the company name need to be dealt with through ASIC rather than only updated in your own records.

Practically, put a recurring reminder in place to review the company's registered details, and set up a habit of checking who is recorded as a director or shareholder after any internal change. Confirm current lodgement timeframes and any fees directly with ASIC.

Where applications usually go wrong

These are recurring process problems rather than legal advice:

Next steps

Work through these in order:

  1. Confirm a company is the right structure for your situation with ASIC's material and, if the decision is close, a registered accountant or lawyer.
  2. Shortlist two or three company names and check availability through the official channels.
  3. Read the current ASIC and BRS requirements for directors, shareholders and company details, and gather the information they ask for.
  4. Register the company through the Business Registration Service and complete the associated tax registrations in the same flow.
  5. Check ABLIS for licences and permits, and ASIC's AFS licence material if you are providing financial services.
  6. Store the ACN and registration confirmation, then set a recurring review of your company details on the register.

If part of your plan involves property finance for the business, treat that as a separate decision and compare options in your own time — you can start at /money/home-loans/.
