Starting a company in Australia is a significant step that comes with both benefits and responsibilities. Whether you are incorporating a new company or already managing one, understanding the key aspects of this business structure is crucial. This guide covers essential information, including legal obligations, tax implications, and financial responsibilities.
What is a Company?
A company is a separate legal entity distinct from its directors and shareholders. This means it has its own rights and obligations, including:
Separate Tax and Superannuation Obligations: The company is responsible for its own tax payments and superannuation contributions.
Ownership of Income and Assets: All income and assets generated by the company belong to the company, not the shareholders.
Director-Run, Shareholder-Owned: The company is managed by its directors and owned by its shareholders.
Key Legal and Regulatory Requirements
1. Regulation by ASIC
Companies in Australia are regulated by the Australian Securities and Investments Commission (ASIC). Compliance with ASIC rules is essential to maintain company registration.
2. Director Identification Number (Director ID)
All company directors must obtain a Director ID before their appointment. This unique identifier helps prevent fraudulent activity and ensures accountability.
3. Higher Setup and Administration Costs
Compared to sole traders and partnerships, companies typically have higher establishment and ongoing administrative costs due to additional compliance requirements.
4. Increased Reporting Obligations
Companies are subject to more stringent reporting requirements, including financial statements, tax filings, and ASIC compliance updates.
5. Director Penalties and Personal Liability
While a company provides asset protection, directors can still be held personally liable for certain debts, including:
Unpaid PAYG withholding tax and superannuation contributions (under the Director Penalty Regime)
Insolvent trading or breaches of director duties under the Corporations Act
Financial and Tax Obligations
1. Tax File Number (TFN) and Australian Business Number (ABN)
A company must obtain its own TFN and is eligible for an ABN for business operations.
2. Goods and Services Tax (GST) Registration
Companies must register for GST if:
Their annual GST turnover is $75,000 or more ($150,000 for not-for-profits)
They provide taxi, limousine, or ride-sourcing services
They intend to claim fuel tax credits
3. Business Activity Statements (BAS)
Companies registered for GST must lodge BAS, which reports:
GST collected and paid
PAYG withholding obligations for employees
PAYG instalments for income tax prepayments
4. Company Tax Return and Income Tax Obligations
All companies must:
Lodge an annual company tax return
Pay income tax at the applicable company tax rate
Pay Pay As You Go (PAYG) instalments throughout the year
5. Superannuation Guarantee (SG) Contributions
Companies must pay superannuation guarantee contributions for eligible employees, including directors who receive wages.
6. Dividend Distribution and Franking Credits
Companies can distribute profits to shareholders via dividends.
Franking credits may be attached to dividends to prevent double taxation.
Companies must issue distribution statements to shareholders receiving dividends.
7. Personal Use of Company Funds
Using company money or assets for private purposes can have tax consequences, such as fringe benefits tax (FBT) or deemed dividends (Div 7A rules).
Asset Protection and Liability
A company limits liability by being a separate legal entity, protecting personal assets from business debts.
However, directors may still be personally liable for certain obligations, including unpaid tax and superannuation under ATO rules.
Company Deregistration
Deregistering a company involves a formal process with ASIC, which includes meeting financial obligations and ensuring there are no outstanding debts. Failure to properly deregister can result in ongoing compliance responsibilities.
