Why your choice of entity matters
Selecting the right business structure is foundational. Your entity type affects:
- Tax rates and access to deductions (e.g. company vs individual rates).
- Liability exposure — companies and trusts often protect owners more than sole traders or partnerships.
- Access to incentives and eligibility under rules such as thin capitalisation, global minimum tax, or venture capital tax concessions.
Here are the main types in Australia:
| Entity Type | Who it suits | Key tax implications |
|---|---|---|
| Sole trader | Individuals starting small, low compliance burden | Income taxed at personal rates; limited liability protection |
| Partnership | Two or more individuals sharing risks/profits | Partners taxed individually; partnership itself not taxed |
| Company | Growing ventures, wanting limited liability | Company tax rates; dividends may carry franking credits |
| Trust | Families, wealth protection, flexible distributions | Trust has no ATO tax if properly distributed; complex record keeping |
Recent changes impacting entity setup decisions
- The implementation of Pillar Two global and domestic minimum tax means large multinational entities in Australia face a 15% minimum tax on foreign low-taxed income, effective from fiscal years starting 1 January 2024 for the Income Inclusion Rule, and 1 January 2025 for Undertaxed Profits Rule.

- New thin capitalisation and Debt Deduction Creation Rules (DDCR) impact how private groups deduct interest from related parties or restructure debt. (ato.gov.au)

Examples
Example A: Startup tech founder expecting rapid growth and foreign investment. Chosen structure: company with dual-share class. Benefit: company tax rate, ability to issue equity, limit personal liability.
