Business Structures Explained

Business Structures Explained: Company, Trust, Partnership & Sole Trader


When launching or growing a business, one of the most important decisions you’ll make is choosing the right business structure. The structure you select affects your tax obligations, asset protection, risk exposure, and long-term growth potential.

At Sterling Business Advisory, we work closely with clients to help them understand the benefits and hurdles of operating as a sole trader, partnership, company, or trust, ensuring their business is structured for lasting success.

Sole Trader – Simple & Cost-Effective

A sole trader structure is the easiest and most affordable way to start a business.

Advantages:

  • Complete control over all business decisions.
  • Minimal setup costs and simple reporting.
  • Straightforward to manage.

Considerations:

  • No asset protection or legal separation – you’re personally liable for all debts.
  • Profits taxed at personal marginal rates (which may not be tax-efficient as your income grows).

Partnership – Shared Ownership & Responsibility

A partnership involves two or more people running a business together.

Advantages:

  • Easy and inexpensive to establish.
  • Shared management, skills, and financial input.
  • Income distributed among partners for tax purposes.

Considerations:

  • Partners are personally liable for debts and legal obligations.
  • Disputes can arise without a clear partnership agreement.
  • Less flexibility for growth or succession planning.

Company – Protection & Professionalism

A company structure is a separate legal entity that offers greater protection and scalability.

Advantages:

  • Limited liability for shareholders.
  • Flat corporate tax rate (25% for base rate entities).
  • Improved credibility with lenders and investors.
  • Suitable for long-term growth and reinvestment.

Considerations:

  • Higher setup and compliance costs.
  • More detailed record-keeping and ASIC reporting obligations.

Trust – Flexibility & Asset Protection

A trust allows income and assets to be held for the benefit of others (the beneficiaries).

Advantages:

  • Tax-effective distribution of profits to beneficiaries.
  • Strong asset protection when structured correctly.
  • Common for family businesses and wealth-building strategies.

Considerations:

  • Higher establishment costs than some other structures.
  • Annual trust resolutions and ongoing compliance required.

Which Structure is Right for You?

There is no one-size-fits-all solution. The right choice depends on your business size, industry, risk exposure, family circumstances, and growth ambitions. What may work at the start-up stage might not be appropriate as your business expands.
