When choosing a one or two company business structure for your startup, it is important to consider the advantages and disadvantages of each as well as how to structure your personal shareholding. Factors such as costs, the complexity of processes, protection of assets, tax and liability are critical in determining your startup structure. It is also sensible to take note of your future goals, whether or not you plan to expand your startup nationally and internationally to ensure your business structure suits your future needs and you avoid complexities and costs associated with restructuring later down the track.

One Company Structure

A one company structure is a single company that captures all the business’ responsibilities in the sense that it trades on behalf of the startup, enters into business contracts, retains ownership of all assets including intellectual property, bears liability and employs employees.

A company is a separate legal entity, and so shareholders have no legal or beneficial interests in any assets. Consequently, shareholders are not liable on behalf of the company, to the extent stated in the company constitution and the Corporations Act 2001

Although the one company structure is comparatively simpler and the shareholders have limited liability, this structure doesn’t protect assets from third parties or provide tax-free dividends. If someone sues the company, its assets are at risk to satisfy any debts. 

Two Company Structure

A two-company structure consists of an operating subsidiary company that undertakes the following: 

  • Trades on behalf of the business;
  • Enters into contracts; 
  • Incurs liabilities; and 
  • Employs employees.

The holding company owns all of the business assets including any property, and intellectual property. Having both an operating company and a holding company provides greater asset protection than the one company structure. 

As the company holding assets is distinct and separate from the operating company, your valuable assets are afforded greater protection from third parties, employees, clients, creditors and suppliers.

Another advantage of the two company structure is tax-free dividends. Under the Income Tax Assessment Act 1997, dividends paid from an operating company to a holding company are tax-free as opposed to dividends paid by a company to an owner who has to pay tax. Avoiding tax on dividends allows you to reinvest the saved money efficiently and effectively to benefit your startup.

While the two company structure offers advantages, it also has some disadvantages that are important to note. There are associated complexities with setting up the two companies separately including but not limited to costs, legalities and agreement between the companies. Furthermore, if an operating company acts on behalf of the holding company in the scope of an agent, as per the laws surrounding agency, the holding operating company will be liable for agent’s actions.

The holding company is a separate legal entity from the operating company. Although, in exceptional circumstances, the court may look past the separation of the two companies and view the holding company as the operating company’s shareholder, ‘piercing’ the corporate veil.

While setting up two companies is more complex than setting up one, a significant advantage is its ability to protect assets. While you may currently not have many assets that require protection, it is important to have a business structure that is ready to accommodate the future needs of your startup. 

Personal Holding of Shares

When choosing a company structure for your startup, it is also vital to consider the structure to hold your shares within the company. The different structures each have their respective advantages and disadvantages, but ultimately the structure best suited to holding your shares whether it be individually, through a company or a trust should be determined by your goals and needs regarding your startup.


Within a company, you can choose to hold your shares as an individual – this is comparatively less complex and costly to a company and a trust. Furthermore holding shares in a company as an individual grants you a discount on capital gains tax when you sell the shares, provided you hold the shares for over 12 months. Although owning your shares as an individual is cost-effective, it may not provide you with tax benefits or limited liability that comes with holding your shares in a company or a trust.


Holding your shares within a company has similar advantages to a company business structure, including:

  • Shareholders have limited liability; 
  • Cost-effective set-up;
  • Flexibility for shareholders to decide on their reinvestment strategies; and 
  • Deciding where to direct dividends (to themselves or the holding company). 

However, holding your shares in a company attracts the following disadvantages:

  • Lack of privacy as financial affairs are public;
  • Profits distributed to shareholders are taxable, and
  • Shareholders are not entitled to a capital gains tax discount if they do sell their shares.

Should you choose to follow the two company structure in setting up your startup, the holding company would ‘hold’ your shares.


Holding your shares in a trust may be advantageous including flexibility in distributing income, asset protection and ease in passing the trust on to another trustee. A trust, however, is liable to pay stamp duty and capital gains if the trustee sells its shares. 

Holding shares via a trust is more beneficial than holding shares as an individual or as a company in the sense that it provides asset protection.

Key Takeaways

Every business structure whether it be one company or an operating and holding company in a two-company structure has its advantages and disadvantages. When setting up your startup, perhaps the most important legal and business considerations involve asset protection and money. The structure best suited to your startup is dependent upon your business’ needs and future goals.
