Tax time in Australia can be complex — especially if you’re not across the latest rules, deductions, and reporting requirements. Whether you’re an employee, small business owner, investor, or part of a dual-income household, understanding your income, entitlements, and responsibilities can lead to a better refund outcome — or a reduced tax bill.
At Bottrell Accountants, we’ve worked with thousands of individuals, couples and families across Australia to help them maximise deductions, avoid ATO red flags, and ensure their tax position supports their long-term financial goals. This page is your complete guide to understanding personal tax deductions in Australia.
A tax deduction reduces your taxable income. You don’t get the amount back in cash, but it lowers the income figure the ATO uses to calculate your tax.

To legally claim a deduction, you must:
All income must be declared in your tax return, even if it was earned overseas, paid in cash, or split across multiple jobs or accounts. The ATO receives pre-filled data from many sources, so accurate reporting is essential.
