Tax offsets help reduce your ultimate
tax liability. Some of the common offsets are explained below:
Medical Expense Tax Offset
Low Income Tax Offset
Private Health Insurance Tax Offset
Other tax offests apply to people with dependants, those living in remote areas and those who receive particular types of income or incur particular expenses.
A partnership that is carrying on
a business must show in a Partnership
Tax Return all it's income earned and deductions claimed for expenses
in the course of carrying on business.
Each partner pays tax on their share of the partnership's income, and thus must
include their individual share of the net partnership profit or loss in their
personal tax return.
Instructions are available at the ATO website www.ato.gov.au.
A company is a distinct legal entity, with it's own income tax liability, and must complete a Company Tax Return. A company's income tax is calculated as a percentage of the taxable income the company earned during the financial year. The company tax rate is 30 percent.
The amount of tax to be paid is reduced by any PAYG instalments payable during the year.

Car Benefits – Statutory Formula
For car benefits, rather than using the operating cost method (which requires a log book), taxpayers can choose to use the statutory formula which is effectively based on the number of business and private kilometers travelled in a year. The rates are as follows:
Annualised Number of Kilometres |
Rate |
Less than 15,000 |
26% |
15,000 to 24,999 |
20% |
25,000 to 40,000 |
11% |
More than 40,000 |
7% |

The rate of depreciation in most cases is determined by the assets effective life. There are generally two methods available for calculating the rate of depreciation.
The ‘Prime Cost’ method offers straight line or uniformed depreciation over the life of the asset.
The ‘Diminishing Value’ method offers greater depreciation in earlier years.
A taxpayer in most cases can self-assess the asset’s effective life. Although the preferred method, known as the ‘safe harbor’ approach is to rely on the Commissioner’s determination of effective life. These determinations are found in Taxation Ruling TR 2000/18.
