In Australia, approximately 20,000 new companies are registered each month. There are different types of companies, but the most common company type is a proprietary limited company (a private or Pty Ltd company). The proprietary limited company structure offers:
- growth options;
- protection from personal liability; and
- potential tax benefits.
However, registering a company does impose serious responsibility on directors. It is important to be aware of your duties as a director. This is because breaching these duties can attract fines or even criminal liability. This article explains the major advantages and disadvantages of running a proprietary limited company.
Proprietary Limited Company Structure
A company is its own legal entity. It can enter into contracts and sue other entities. Other entities can also sue it. A proprietary limited company is a private (not public) company that does not sell its shares to the general public and can have a maximum of 50 shareholders.
There is a limit to shareholders’ legal responsibility for company debts. This is the amount that shareholders have not paid for their shares (limited liability). This is usually zero, as most shareholders pay for their shares fully when they acquire them.
Shareholders own the company by owning shares in the company. Likewise, the company management consists of:
- one or more directors; and
- the company secretary (optional).
Advantages of Operating as a Company
Limited Liability
As a company is its own legal entity, it is liable for its own debts. This means that if another party makes a successful claim against the company, you can only pay back the claim using the company’s cash reserves and assets. The claim cannot come after the shareholders’ or directors’ personal assets. This is unlike being a sole trader, where your personal assets may be at risk if you need to satisfy any claims or debts. However, if a company director breaches their duties or provides a personal guarantee to a contract, their personal assets will not be at risk of exposure.
While a single company structure protects the personal assets of its shareholders, a large claim may cripple the business if it calls on the business’ assets to pay the debt. Alternatively, you could consider setting up a dual company structure if:
- there is a risk that customers or contractors will sue your business; or
- you have very valuable intellectual property that you need to protect.
A dual company structure will help protect your business assets from claims made against the company.
Attracting Investors, Customers and Suppliers
If a business has growth plans that require third-party investment, generally, investors are more likely to invest in company structures. A company is an attractive investment structure because it gives investors:
- security through limited liability;
- flexibility to sell their shares or purchase more; and
- transparency, as you must keep company information up to date on the public ASIC register.
A registered company implies that the business operates on a larger and more serious scale, assisting business owners at the negotiation table. Customers also feel more confident when dealing with companies. It can even help some businesses win contracts.
Tax Efficiency
Individuals, including sole traders, are taxed at the standard marginal rates, depending on the level of income, with the highest rate at 45% (as of July 2019). In contrast, a company’s tax rate is a flat 27.5% (or 30% for large companies), regardless of its profits. This can make a significant difference to the viability of a business.
Further benefits are that companies:
- can offset tax losses from one business against profits made by another; and
- may be able to carry tax losses forward into future more profitable years.
Avoiding Conflict
Registering a company can help avoid conflict between business owners. The number of shares a shareholder owns determines their percentage ownership of the company.
The essential document governing shareholder relationships is the shareholders agreement. You will typically create this document when registering the company. This document provides significant protection against company disputes, particularly when one shareholder departs the company. Likewise, it regulates the rights and responsibilities of shareholders and important business activities, such as how the company will:
- issue shares;
- pay dividends; and
- resolve conflicts.
Succession
As a company is its own legal entity, it will exist indefinitely until you wind it up. If a shareholder or director dies, you can take steps to replace them, and the business can continue to trade.
Difficulty can arise if a shareholder dies and there is no shareholders agreement. In this case, the shares are given to the nominated next of kin in accordance with the shareholder’s will. This might mean that in a 50/50 partnership, the remaining business partner must suddenly own the business with their former partner’s relative, who may have no business experience. To avoid this difficult situation, the shareholders agreement may stipulate that if a shareholder dies or leaves the company, you must sell the shares back to the company.

Disadvantages of Operating as a Company
Directors Duties
Before registering a company, it is essential that prospective directors fully understand their responsibilities. If a director breaches their duties, they may have to pay certain company debts personally or they may be prohibited from managing another company. A director who breaches their duties may need to pay a fine or find themselves criminally liable and face jail time.
The key directors’ duties are to:
- prevent the company from trading while insolvent;
- ensure the company complies with all legal obligations (see below);
- act in good faith in the best interests of the company and avoid conflicts with personal interests;
- be careful and diligent when running the company; and
- report on the company’s affairs to the liquidator and give them all relevant books and records if the company in the event of a wind-up.
Directors are unlikely to run into any issues if they take an active role in the business, understand their legal obligations and prioritise legal compliance. If directors are uncertain about their obligations in a situation, it is important to seek legal advice sooner rather than later.

If you are a company director, complying with directors’ duties are core to adhering to corporate governance laws.
This guide will help you understand the directors’ duties that apply to you within the Australian corporate law framework.
Complying with Obligations
Directors are responsible for ensuring the company complies with all obligations set out in corporations law.
Some of the most important responsibilities are:
- maintaining up-to-date financial records;
- ensuring good governance (e.g. ensuring proper decision making);
- notifying ASIC of certain company changes; and
- paying ASIC’s fees.
Tax
Companies must lodge an annual company tax return. Unlike tax for an individual or sole trader, there is no initial tax-free threshold for companies. Companies are taxed at the 27.5% tax rate from the first dollar earned. However, if the company distributes profits to shareholders as dividends, these profits will be taxed at each shareholder’s tax rates (less any franking credits). Companies are also not eligible for the 50% capital gains tax discount (which individuals and sole traders receive).
Notably, unlike the sole trader and partnership structures, if a company makes a loss, this loss is trapped within the company and cannot be used to offset other personal income.
If a company’s income is mostly derived from one person’s efforts, skill or expertise, the company’s income may be treated as individual income for tax purposes.
Expenses
Registering a company costs $495 in government fees, plus professional service fees if you are hiring a lawyer or accountant to set it up. An annual ASIC reporting fee of $267 applies, as well as ongoing accounting costs to maintain a proper set of company accounts.
Key Takeaways
A company structure provides the advantages of limited liability, growth potential, and certain tax efficiencies. However, setting up and operating a company is more expensive, can have certain tax disadvantages, and is highly regulated.

Frequently Asked Questions
A proprietary limited company (that is, a private or Pty Ltd company) is a type of business structure that establishes a company as its own legal entity. It can enter into contracts and legal relations. It can only have a maximum of 50 shareholders, and there is a limit to the shareholders’ responsibility for company debts.
Proprietary limited companies are advantageous for several reasons. First, a private company is its own legal entity. This means that you and your shareholders will not be held personally liable for any debts incurred by the company. Second, investors, customers and suppliers will often feel more comfortable when dealing with a registered company. Third, successful companies will benefit from a flat company tax rate of 27.5% (or 30% for larger companies). In contrast, sole traders can pay up to 45% of their income in tax. Fourth, registering a company and creating a shareholders agreement will help to avoid conflict between business owners. Finally, if a shareholder or business owner dies or leaves the business, they can be replaced within the company without needing to establish a new structure.
There are some disadvantages to establishing a proprietary limited company. First, you will need to ensure that your company directors comply with the directors’ duties. Second, you must comply with various obligations set out in corporations law, such as maintaining up-to-date financial records and notifying ASIC of certain company chances. Third, companies do not benefit from the same tax-free threshold enjoyed by individuals, nor the 50% capital gains tax discount received by sole traders. Finally, private companies have higher setup and operating expenses.
