An income tax audit in Perth can feel stressful, especially if you don’t know why the Australian Taxation Office (ATO) has reached out to you or what they are asking for. Many people and businesses feel nervous simply because they don’t really understand the audit process. But once you learn how an income tax audit works, it feels way easier to deal with.
The ATO may audit individuals, sole traders, small businesses, or company directors to check if income, deductions, and tax records are correct. Being chosen for an audit doesn’t always mean you did something wrong. A lot of the time, audits are just part of the ATO’s normal checks.
At ISM Accountants, we help individuals and businesses across Perth during ATO income tax audits. We guide you through every step, talk to the ATO for you, and make sure your rights are protected. Our main goal is simple: lower risk, cut down penalties, and help you get the best result with confidence and peace of mind.
What Is an Income Tax Audit?
An income tax audit is a formal check done by the Australian Taxation Office (ATO). The ATO goes through your tax returns and money records to make sure the income you reported and the deductions you claimed are correct.
The ATO may audit:
- Individual taxpayers
- Sole traders and freelancers
- Small and medium businesses
- Companies and trusts
An audit does not always mean you did something wrong. In many cases, it is part of the ATO’s normal compliance process.

Why Does the ATO Conduct Income Tax Audits?
The Australian Taxation Office (ATO) does income tax audits to make sure the tax system is fair and works well for everyone. These audits help the ATO check that people and businesses report their income correctly, claim the right deductions, and pay the correct amount of tax under Australian tax laws.
An income tax audit does not always mean you did something wrong. In many cases, the ATO picks taxpayers as part of regular checks. The main aim is to find small mistakes, fix reporting problems, and lower tax risks before they turn into bigger issues.
By doing audits, the ATO also encourages people to follow the rules and makes sure honest taxpayers are treated fairly.
Common Triggers for an Income Tax Audit
You might be chosen for an income tax audit in Perth if the ATO sees something in your tax records that looks unusual or does not match other information they have.
Some common reasons the ATO may start an audit include:
Income that does not match bank records or other reports, such as details from your employer or payment apps
- Very high or unusual deductions, especially if they are much higher than others in the same industry
- Cash-based business activities, where income is harder to track
- Business losses reported again and again over several years
- GST or BAS figures that do not match your income tax returns
- Industry benchmarks, where your results are very different from normal ranges
The ATO uses smart systems to match data, so even small differences can get noticed. That is why keeping clear records and reporting the same information every time is so important.
Getting help early can fix small issues quickly and stop them from turning into bigger problems or penalties. It is a good idea to speak with ISM Accountants’ experts for support with your income tax audit.

Types of Income Tax Audits in Australia
Not all income tax audits are the same. The Australian Taxation Office (ATO) uses different types of audits depending on how risky the situation is, the taxpayer’s history, and how complicated the tax matters are. Some audits are simple and can be handled by email, while others are more detailed and might take several months.
Knowing what type of audit you’re facing helps you get ready properly and respond with confidence.
Desk Audit
A desk audit is the most common and simplest type of income tax audit. It’s usually done through letters, emails, or phone calls, without any in-person meetings.
The ATO may ask you to provide:
- Receipts or invoices
- Bank statements
- Proof of deductions
- Income records
Desk audits are often for individual taxpayers or simple tax matters. Even though they’re lower risk, it’s still important to respond accurately and on time.
Field Audit
A field audit is more detailed than a desk audit. In this case, an ATO officer might visit your business or your accountant’s office to check your records in person.
Field audits are usually for:
- Small and medium-sized businesses (SMEs)
- Sole traders with complex transactions
- Businesses with higher audit risk
The ATO will carefully look at your financial records, systems, and reporting practices. Having a professional represent you is highly recommended at this stage.
Comprehensive Income Tax Audit
A comprehensive income tax audit is the most detailed type of audit done by the ATO. It covers a full review of your tax affairs and often looks at multiple financial years.
This type of audit usually applies to:
- Companies and corporate groups
- Trusts and partnerships
- High-income or high-risk taxpayers
Comprehensive audits may involve several meetings, detailed document checks, and long communication with the ATO. Expert tax audit support is very important to manage risk and lower possible penalties.
Comparison of Income Tax Audit Types
Audit Type | Where It Happens | Complexity | Common For |
Desk Audit | ATO Office (remote) | Low | Individuals |
Field Audit | Business or Accountant’s Office | Medium | SMEs |
Comprehensive Audit | Multiple Locations | High | Companies & Trusts |
Each type of audit needs a different level of preparation. Knowing what to expect helps you respond properly and avoid unnecessary stress.

Who Can Be Audited in Perth?
The ATO can audit almost anyone who lodges a tax return in Australia. Audits are not only for big businesses. They can also include individuals, small businesses, and trusts.

- Sole Traders and Freelancers: Cash income, home office claims, and business expenses are often checked closely.
- Companies and Corporations: The ATO pays close attention to company income, payments made to directors, and deals between related parties.
- Trusts and Partnerships: Trust distributions and how income is reported for beneficiaries can also draw ATO attention.
Being chosen for an audit does not automatically mean you did something wrong. Being prepared and keeping accurate records helps make the process easier and less stressful.

Income Tax Audit Process in Perth, Australia
Facing an income tax audit in Perth can feel stressful, but knowing how the process works makes it much easier. The Australian Taxation Office (ATO) follows a clear process to check tax returns. Understanding each step helps individuals and businesses reply the right way, avoid errors, and save time. Whether you are a sole trader, company director, or investor, keeping accurate records is the key to a smooth audit.
- Audit Notification: The ATO contacts you by letter or phone to tell you that your tax return has been chosen for review. This is the official start of the audit.

These can include income tax returns, notices of assessment, bank statements, invoices, receipts, payroll and PAYG records, BAS and GST reports, and lists of assets or depreciation. Keeping your documents neat and ready helps the audit move faster and lowers risk.
- Review and Analysis: The ATO carefully checks your records to make sure your income, deductions, and other financial details are reported correctly.

What Happens If Errors Are Found During an Income Tax Audit in Perth?
