For tax purposes, you should keep records of all income, expenses, receipts, invoices, bank statements, and any other financial documents. These records will help you accurately report your income and claim deductions.

In Australia, small businesses are subject to various tax liabilities. Here are the key types of taxes that small businesses may need to consider:

1. Income Tax

Small businesses in Australia are required to pay income tax on their profits. The tax rate for small businesses is generally lower than for larger corporations. As of the latest updates, the company tax rate for small businesses with an aggregated turnover of less than $50 million is 25%.

2. Goods and Services Tax (GST)

If a small business has a turnover of $75,000 or more, it must register for GST. This tax is charged on most goods and services sold or consumed in Australia. Businesses must collect GST from their customers and remit it to the Australian Taxation Office (ATO).

3. Pay As You Go (PAYG) Withholding

Small businesses that have employees must withhold tax from their employees' wages under the PAYG system. This tax is then paid to the ATO on behalf of the employees.

4. Fringe Benefits Tax (FBT)

If a small business provides certain benefits to employees (such as cars or entertainment), it may be liable for Fringe Benefits Tax. This tax is separate from income tax and is calculated on the taxable value of the benefits provided.

5. Superannuation Contributions

Employers are required to make superannuation contributions for their employees. The current minimum superannuation guarantee rate is 11% of an employee's ordinary time earnings, which must be paid to a complying super fund.

6. State and Territory Taxes

In addition to federal taxes, small businesses may also be liable for various state and territory taxes, including:

• Payroll Tax (for businesses with a certain level of payroll)

• Stamp Duty (on certain transactions, such as property purchases)

• Land Tax (for property owners)

7. Other Considerations

Small businesses may also be eligible for various tax concessions and deductions, such as:

• Small Business Income Tax Offset

• Instant Asset Write-Off for eligible assets

• Small Business CGT Concessions

The frequency of lodging your BAS depends on your business's annual turnover. Generally, businesses with a turnover of less than $20 million lodge their BAS quarterly. However, some businesses may need to lodge monthly or annually based on their specific circumstances.

An Instalment Activity Statement (IAS) is a form used by taxpayers who are required to make pay-as-you-go (PAYG) instalments. It is used to report and pay PAYG instalments, PAYG withholding, and other tax obligations.
