What is a Tax Deduction?

Types of Income.

End of Year Tax Returns

 

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.

 

What Is a Tax Deduction?

 

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.

Example: If you earn $90,000 and claim $5,000 in deductions, the ATO calculates your tax on $85,000. This can reduce how much tax you owe, or increase your refund.

To legally claim a deduction, you must:

  • * Have paid for the item or service yourself
  • * Ensure it relates directly to your income
  • * Keep records to prove it (e.g. receipts, logs)
  •  

Types of Income You Must Declare

 

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.

Income categories include:

  • * Employment income: salary, wages, bonuses, commissions, allowances
  • * Government payments: Centrelink, JobSeeker, Parenting Payment, pensions
  • * Investment income: interest, dividends, distributions, trust income
  • * Rental income: including from Airbnb, short stays, and long-term tenants
  • * Business or sole trader income: freelance work, contract income, online business sales
  • * Capital gains: on assets like shares, property, or cryptocurrency
  • Foreign income: if you’re an Australian tax resident
  •  

Failure to declare all income may result in ATO penalties, interest charges, or audits.

  • * Travel logs, diaries, rosters
  • * Share trading and crypto records
