Is a company right for your business?

A proprietary limited company (Pty Ltd) is the most common vehicle for Australian businesses that want limited liability, clean ownership, and investor readiness. Before you incorporate, compare it with alternatives and confirm tax and governance settings.

When a company makes sense

  • You want limited liability and to separate business risk from personal assets
  • You plan to add investors, issue shares or run an ESOP
  • You need credibility for tenders, enterprise customers or export
  • You want clear ownership, sale and exit options

When to consider other options

  • Very small side business with minimal risk (sole trader)
  • Professional practice or family distribution goals (trust with corporate trustee)
  • Short-term project with simple revenue sharing (partnership, with caution)

Ask a lawyer which structure fits your goals

Important: The best structure depends on your facts, state or territory laws, tax profile and industry rules. This page is general information only.

Company setup FAQ

Do I need a company to trade in Australia?

No. You can trade as a sole trader or partnership, but a company offers limited liability, clearer ownership and is often preferred for growth and investment.

What should I decide before registering?

Directors and shareholders, share classes and percentages, company name, registered office, governance (constitution vs replaceable rules), and whether you need a shareholder agreement.

Can I use replaceable rules instead of a constitution?

Yes, but a tailored constitution can address share classes, pre-emption, drag/tag and other points that matter once investors or employees hold equity.

Will I need GST registration?

You must register if your GST turnover meets the threshold. Some industries register earlier for input credits and invoicing expectations.

How do I keep costs predictable?

Ask for a fixed-fee bundle that includes incorporation, constitution, ABN/GST, initial registers and a short shareholder agreement workshop.
