If you are a sole trader, you have to use your individual tax file number when lodging your income tax return. There is no separate business tax return for sole traders. As a sole trader, you personally own your business & you are personally liable for business taxes & debts. 

A sole trader is an individual running a business. It is the simplest and cheapest business structure. If you operate your business as a sole trader, you are the only owner, and you control and manage the business. You are legally responsible for all aspects of the business. Debts and losses can’t be shared with other individuals. You can employ workers in your business, but you can’t employ yourself. As a sole trader, you are responsible for paying your worker’s super. You’re also responsible for your own super and may choose to pay it into a fund for yourself to help save for your retirement.

As a sole trader, you:

• use your individual tax file number when lodging your income tax return
• report all your income in your individual tax return, using the section for business items to show your business income and expenses (there is no separate business tax return for sole traders)
• apply for an ABN and use your ABN for all your business dealings
• register for Goods and Services Tax (GST) if your annual GST turnover is $75,000 or more
• pay tax at the same income tax rates as individual taxpayers, and you may be eligible for the small business tax offset
• put aside money to pay your income tax at the end of the financial year – usually, you will do this by paying quarterly Pay As You Go (PAYG) instalments
• claim a deduction for any personal super contributions you make after notifying your fund.

As a sole trader, you can’t claim deductions for money ‘drawn’ from the business. Amounts taken from the business are not wages for tax purposes, even if you think of them as wages.
