How To Register A Company In Australia

Thinking about registering a company in Australia? It’s a big milestone - and a smart way to set your business up for growth, investor confidence and clearer risk management.

If you haven’t done it before, it can feel like a maze. There are decisions to make about shares and directors, forms to lodge, and ongoing compliance to plan for.

The good news: when you break it into steps, it’s very manageable. In this guide, we’ll explain what a company is, whether it’s the right structure for you, how to register with ASIC, and the key legal documents to have in place from day one.

Is A Company The Right Structure For You?

Before you dive into registration, it’s worth confirming the structure that fits your goals, appetite for risk and budget. In Australia, your main options are:

• Sole trader: Quick and low-cost. You operate as an individual with an ABN. However, there’s no separation between your personal and business assets, so you’re personally responsible for business debts.
• Partnership: Two or more people (or entities) carry on business together. Setup is still relatively simple, but partners can be jointly liable for obligations.
• Company: A separate legal entity that can own assets, enter contracts and take on debts in its own name. Directors manage the company and shareholders own it. The biggest advantage is limited liability (your personal assets are generally protected if you comply with your directors’ duties).
• Trust: A trustee (an individual or a company) holds assets for beneficiaries. Often used for asset protection or tax planning. More complex to set up and maintain.

Many founders choose a company structure for limited liability and flexible equity - especially if they plan to bring in co‑founders, employees or investors later.

Tip: If you’re unsure whether you (or a co‑founder) meet the Australian residency rule for directors, it’s worth checking the Australian resident director requirements early.

What To Decide Before You Register

Company registration moves faster when you’ve made these key decisions up front.

1) Your Company Name

Pick a unique name and check it’s available. If your preferred name includes restricted words (for example, “bank” or “university”), you may need extra approvals. You can also register a generic company name now and later register a separate business name for trading if you want a different brand.

2) Registered Office & Principal Place Of Business

You’ll need an Australian registered office address (where official notices can be sent) and a principal place of business. If you use a third‑party address, get written consent to use it.

3) Directors, Secretaries - And Director IDs

You must appoint at least one director, and at least one director must ordinarily reside in Australia. Directors and secretaries must be 18 or older and consent in writing to their appointment.

Each director also needs a director identification number (director ID) obtained from the Australian Business Registry Services (ABRS). New directors must have their director ID before they are appointed. Plan this step early so it doesn’t delay your application.

4) Share Structure & Shareholders

Decide which shares you’ll issue (most startups begin with ordinary shares), how many shares will be on issue at registration, the price per share (often nominal at startup), and who will hold them. If you expect to scale, think about vesting, option pools and whether different classes of shares might be useful down the track.

5) Company Rules: Constitution Or Replaceable Rules

Under the Corporations Act, you can rely on replaceable rules (default rules in the legislation) or adopt a customised Company Constitution. Many founders prefer a tailored constitution so their document reflects how they actually make decisions, handle share transfers and manage director powers.

6) Consents & Personal Details

Collect written consents from directors, secretaries and shareholders, and have personal details (full legal names, service addresses, dates of birth) ready for the application.

7) Co‑Founder Alignment

If you have more than one founder, agree on roles, equity splits, decision‑making, vesting and exit scenarios. Capturing these terms in a Shareholders Agreement helps prevent disputes later and makes future investment due diligence smoother.

Step‑By‑Step:

Company registrations are handled by the Australian Securities and Investments Commission (ASIC). You can register directly with ASIC or engage professionals to set it up and prepare your foundation documents.

Step 1: Confirm Your Structure And Choose A Name

Confirm that a company is your preferred structure, pick your name, and consider whether you’ll also register a business name for trading. If you’d like help with end‑to‑end setup and documents, our team can facilitate a smooth Company Set Up for you.

Step 2: Get Director IDs And Finalise Officeholders

Each incoming director should apply for their director ID with the ABRS. At the same time, confirm your directors and any company secretary, obtain written consents, and gather their personal details.

Step 3: Lock In Your Share Structure

Confirm the number and type of shares on issue, the price per share, and the initial shareholders. If you’re planning options or vesting arrangements for founders or employees, note those for your first board meeting and cap table.

Step 4: Choose Your Company Rules

Decide whether you’ll rely on replaceable rules or adopt a tailored Company Constitution. If you choose a constitution, have it ready to adopt at registration or immediately afterwards via a board resolution.

Step 5: Complete The ASIC Application

The ASIC application will ask for your company name, registered office and principal place of business, officeholder details, and share structure. Double‑check spellings and addresses - fixing errors later can be a hassle.

Step 6: Lodge And Pay The ASIC Fee

Submit the application and pay the ASIC fee. If accepted, you’ll receive an Australian Company Number (ACN) and an ASIC Certificate of Registration. Keep this certificate on hand - banks and other providers commonly request it.

Step 7: Hold Your First Board Meeting

Once registered, hold an initial board meeting (or pass a circulating resolution) to confirm appointments, issue shares, adopt your company rules (if applicable) and authorise practical matters like opening a bank account. Using a clear Directors Resolution format will help keep your company register consistent from the start.

Step 8: Set Up Your ATO Registrations

Apply for an ABN and Tax File Number (TFN) for the company. If your annual GST turnover is or is likely to be $75,000+, register for GST. If you’ll have employees or pay directors’ fees, set up PAYG withholding and Single Touch Payroll.

Note: Tax settings are specific to your business and may change. It’s sensible to check these with your accountant or tax adviser so you’re set up correctly from day one.

What To Do After Registration

Getting your ACN is just the beginning. A few housekeeping steps now will keep you compliant and investor‑ready.

Maintain Your Company Registers

Keep statutory registers up to date (members, option holders, directors and secretaries, charges/security interests if any). Keep copies of signed consents, board minutes and resolutions in your company records.

Are share certificates required? Not necessarily. Many companies don’t issue paper certificates. What matters is that your share register accurately records the issue and ownership - share certificates are optional unless your constitution requires them or a stakeholder specifically requests them.

Appoint A Public Officer (ATO)

Companies must appoint a public officer for tax purposes and notify the ATO. This role is responsible for the company’s tax affairs and should generally be appointed within three months of the company starting to carry on business or derive income. If you’re unfamiliar with the role, our guide to appointing a public officer covers the essentials.

Open A Business Bank Account

Open a dedicated company bank account using your ACN, ABN and Certificate of Registration. Keeping personal and company finances separate is essential for clean bookkeeping and protecting your limited liability position.

Get The Right Insurance

Consider business insurance that suits your industry (for example, public liability, professional indemnity, cyber). Insurance complements your contracts and corporate structure when it comes to managing risk.

Stay On Top Of ASIC Updates

You’ll receive an annual statement and fee notice from ASIC each year. You also need to notify ASIC when details change (for example, new directors, address changes or share issues). Many of these updates are lodged via the same mechanism companies use for changes covered by Form 484 - our breakdown of ASIC change notifications explains what to expect. Set reminders so these updates don’t slip through the cracks.

Essential Legal Documents For New Companies

Good documents make decision‑making smoother, protect your IP and help manage risk. Not every business will need everything listed below from day one, but most companies will need several of them.

• Company Constitution: Your rulebook for director powers, meetings, share transfers and decision‑making. A tailored Company Constitution can reflect your ownership and growth plans.
• Shareholders Agreement: Sets out how decisions are made, what happens if a founder leaves, vesting, drag and tag rights, dispute resolution and more. A robust Shareholders Agreement is essential where there are multiple owners.
• Directors Resolutions & Minutes: Formal records of appointments, share issues, bank authorities and other key decisions. Using a consistent directors’ resolution format keeps your register tidy.
• Employment Contracts & Policies: If you’re hiring, set out roles, confidentiality, IP ownership, remuneration, leave and termination terms. This helps you meet Fair Work obligations and avoid misunderstandings. If you’re engaging non‑employees, use clear contractor agreements instead.
• Customer Terms: If you sell goods or services, put clear terms in place covering pricing, delivery, warranties, Australian Consumer Law compliance and liability caps. If you operate online, pair these with Website Terms.
• Privacy Policy: If you collect personal information (which most businesses do), you’ll need a compliant Privacy Policy explaining how you collect, use and store data.
• IP Assignment & Licences: Ensure core IP created by founders or contractors is owned by the company (or properly licensed) so your business holds its key assets.

Putting these documents in place at the start is usually easier and more cost‑effective than trying to fix gaps when problems arise.

Common Questions About Company Registration

Do I need a company secretary?

Not for a proprietary limited company - it’s optional. Many companies appoint one for governance support, but it’s not required by law.

How many directors does a proprietary company need?

At least one, and at least one director must ordinarily reside in Australia. All directors must have a director ID before they are appointed.

When should I register for GST?

Register if your annual GST turnover is, or is expected to be, $75,000 or more. Some companies register earlier to access input tax credits on setup costs. Speak with your accountant if you’re unsure - GST settings should align with your business model.

Can I trade without a business name?

Yes. You can trade under your company’s full legal name. If you want to use a different brand name, register a business name owned by the company.

What documents will banks ask for?

Typically your ACN, ABN, your ASIC Certificate of Registration, ID for signatories and a directors’ resolution authorising the account opening.

I’m a solo founder. Anything special to consider?

You can absolutely form a company with a single director/shareholder. Keep using formal resolutions and minutes for key decisions - those clean records pay off when you later bring in investors or sell the business.

Key Takeaways

• Decide your name, addresses, officeholders, share structure and whether to adopt a tailored Company Constitution before you lodge your application.
• Each director must have a director ID before appointment, and at least one director must be an Australian resident under the resident director requirements.
• After registration, set up your ABN/TFN, consider GST and PAYG, open a bank account, maintain company registers and appoint your public officer with the ATO.
• Core documents - a Shareholders Agreement, clear customer terms, employment or contractor agreements and a compliant Privacy Policy - help manage risk from day one.
• Stay on top of ASIC notifications and your annual statement. Keep clean minutes and resolutions - a consistent directors’ resolution format makes this easy.
