A Pty Ltd company is a private company with its own legal identity that cannot offer shares to the public and limits shareholders' liability to their share capital.

Also known as: proprietary limited company, proprietary company, Pty Ltd, private company

Key points

  • Pty stands for proprietary (private) and Ltd for limited: shareholders are liable only for their share capital and any unpaid amounts on their shares.
  • A proprietary company can have no more than 50 non-employee shareholders and cannot raise funds by offering shares to the public.
  • It is registered with ASIC under the Corporations Act 2001, receives an Australian Company Number (ACN), and usually needs an ABN to trade.
  • Directors carry statutory duties, including preventing insolvent trading, and can be personally liable for debts the company incurs while insolvent.
  • Limited liability is not absolute: personal guarantees given to lenders and breaches of director duties can put personal assets at risk.

Frequently asked questions

What does Pty Ltd stand for?

Pty is short for proprietary, meaning a private company, and Ltd stands for limited, meaning the shareholders' liability is limited to their share capital and any unpaid amounts on their shares. Together they signal a private company that cannot offer its shares to the public and is registered with ASIC under the Corporations Act.

How many directors does a Pty Ltd company need?

Typically at least one. Directors must be at least 18 years old and not disqualified from managing corporations under the Corporations Act. There are also resident director requirements to check, and each director must hold a director identification number and give written consent before the company is registered with ASIC.

What happens if a Pty Ltd company becomes insolvent?

Directors must stop the company trading once it is insolvent or likely to become insolvent. Trading on while insolvent can make directors personally liable for the debts the company incurs during that period, on top of civil penalties, compensation orders and possible disqualification. Seek specialist legal and accounting advice early if insolvency is a risk.

How quickly can I register a Pty Ltd company?

Electronic registration through ASIC can be immediate, although you should allow a few business days for processing. You need the company name, director and shareholder details, the share structure, a registered office address and each director's written consent. ASIC charges a registration fee, which changes periodically, so check the current amount on ASIC's site.

Does a Pty Ltd company need a constitution?

Not necessarily. A company can rely on the replaceable rules in the Corporations Act instead. A constitution is worth considering when you want to define shareholder rights, share classes or governance arrangements in more detail than the replaceable rules provide, particularly where there are several shareholders with different expectations.
