Deductions you can claim

Claiming deductions when receiving PSI
If you received personal services income (PSI) and the PSI rules apply, the rules limit the deductions you can claim against this income.
You can claim most expenses you incur in running your business as deductions to reduce your taxable income. As a general rule, you can claim your day-to-day business operating expenses in full, in the year you incur them. However, the costs of capital items (such as buildings, machinery and equipment) are generally claimed over a number of years.
Deductions you can claim
When completing your tax return, you're entitled to claim deductions for some expenses, most of which are directly related to earning your income.
Depreciating assets and capital expenses
You can claim a deduction for the decline in value, depreciation, of capital assets, such as buildings, motor vehicles, furniture, and machinery and equipment. Small businesses with an aggregated turnover of less than $10 million can use simplified calculation methods.
Home office expenses for a home-based business
If your home is also your place of business, you can claim income tax deductions for a portion of the costs of owning, maintaining and using your home for this purpose. When you sell your home you may be liable for capital gains tax.
Income and deductions for business
You can claim deductions for costs incurred in running your business, provided the expenses are not of a private or domestic nature.
If you operate a business that makes a loss, you can carry forward that loss and may be able to claim a deduction for it in a future year. The rules differ for different business structures. If you’re a sole trader or a partner in a partnership, you may be able to claim business losses by offsetting them against other income – for example, income you earn from salary or wages.
Motor vehicle expenses
The deductions you can claim for motor vehicle expenses depends on your business structure, the type of vehicle, and how the vehicle is used.
Repairs, maintenance and replacement expenses
You may be able to claim a deduction for repairs to machinery, tools or premises you use to produce business income as long as the expenses are not capital expenses.
Salary, wages and super
You can generally claim a deduction for the salaries and wages you pay to employees, and for super contributions you make for them and for certain contractors. If you’re a sole trader, you can usually claim a deduction for your own super contributions in your personal tax return.
