Taxation Disputes
For most businesses and individuals, tax issues are not generally a day-to-day focus, they become important at a critical moment.
That moment may be receipt of an Australian Taxation Office (ATO) review notice, an assessment requiring further tax to be paid, the imposition of penalties, or the point at which a transaction, investment or restructuring brings the impact of the tax position into sharp relief.
In Australia, taxation is not simply a question of “lodging returns” or “paying tax”. It is a body of law that runs through business operations, investment, income structures and cross-border transactions.
Different taxes (such as income tax, GST and capital gains tax) interact with one another, and the way tax is handled is often directly tied to profit, cash flow and long-term risk. In practice, tax issues tend to fall into two categories:
In tax matters, NS Legal focuses not only on explaining the legal rules but also on helping clients understand the impact of those rules in practice, and where necessary, developing a clear response strategy to manage risk and protect commercial interests.
Compliance and structuring: how to design tax arrangements within the legal framework in a sensible way;
Disputes and enforcement: how to respond when the ATO challenges or adjusts the tax position.
Understanding Tax Law in Australia
The Australian tax system is built on a number of legislative and regulatory frameworks, principally the Income Tax Assessment Act 1936 (Cth), the Income Tax Assessment Act 1997 (Cth), the A New Tax System (Goods and Services Tax) Act 1999 (Cth) and the regulatory framework administered by the Australian Taxation Office (ATO).
For businesses and individuals, tax obligations are not only about “whether tax is payable”. They also cover:
- How taxable income or profit is calculated;
- Which expenses are deductible;
- Whether GST or other indirect taxes apply;
- Whether returns, lodgements or disclosures are required;
- Whether there are cross-border tax issues or complex structural arrangements.
It is important to note that the ATO is concerned not only with outcomes, but also with the reasonableness of the arrangements.
That is to say, even where a structure is formally compliant, if it is considered to have a tax avoidance purpose or to lack commercial substance, it may still be challenged.
Tax issues therefore are not simply accounting matters; they also involve legal judgement and risk assessment.
Key Areas of Tax Compliance
In practice, the tax compliance areas most commonly encountered by businesses and individuals tend to be interrelated. Common core areas include:
| Income Tax | company profits, individual income and related deductions; |
|---|---|
| GST (Goods and Services Tax) | whether a transaction is subject to GST and reporting obligations; |
| Capital Gains Tax (CGT) | the tax effect of disposing of assets or restructuring; |
| Payroll-related taxes (PAYG, FBT) | employee wages and withholding; |
| International Tax | situations involving overseas income or transactions. |
For example, what looks like a routine commercial transaction may simultaneously involve income recognition, GST treatment and future CGT consequences.
Tax compliance therefore cannot generally be approached one tax at a time, the overall impact needs to be understood.
ATO Audits and Investigations
Many clients, on first receiving a notice from the ATO, will treat it as a “routine check”. In practice, an audit or investigation typically means that the ATO has already identified questions about a particular matter.
ATO reviews commonly relate to:
- Inconsistencies between return data and third-party information;
- Challenged deductions or expense claims;
- Corporate structure or transaction arrangements considered unreasonable;
- Errors or omissions in historical lodgements.
At this stage, the key questions usually include:
- What specific issues the ATO is focusing on;
- What documents or explanations are required;
- Whether there is a risk of further tax or penalties;
- How to manage the scope of the issue in the response.
For example, if a business has been claiming a deduction in a particular way over a number of years and the ATO challenges that approach, the issue is usually not limited to one year, it may affect several financial years.
The way the review is handled at this stage often directly affects the risk profile in later steps.

Tax Disputes
Tax disputes typically arise where the ATO challenges a taxpayer’s lodgements or arrangements.
Unlike ordinary commercial disputes, tax disputes turn on specialised rules and evidentiary questions, and are handled through a process that follows a defined procedure. Common types of dispute include:
- Adjustment to income or profit calculations;
- Disallowance of expense claims or deductions;
- Rejection of GST treatment;
- Tax structures characterised as unreasonable or as having a tax avoidance purpose;
- The imposition of additional penalties and interest.
For example, a business may consider that an expense is a normal business cost, while the ATO may take the view that the expense is not deductible and seek further tax together with penalties.
In such cases, the issue often turns on legal interpretation and supporting evidence, not just the accounting treatment.

Dispute Resolution Process
When a tax dispute arises, it does not generally proceed directly to court; it usually progresses through a series of stages. The general flow is:
- Initial communication and response: providing explanations and materials in answer to the ATO’s queries;
- Objection: formally challenging a tax decision;
- Review or Tribunal: re-evaluation of the decision at the administrative level, including by the Administrative Appeals Tribunal (AAT);
- Court proceedings (such as the Federal Court): moving into the judicial stage where required.
Each stage has time limits and procedural requirements. Failure to act within those time limits can affect a taxpayer’s later rights. In practice, most tax disputes are not resolved at the final court stage.
They are usually resolved earlier through legal advice, the marshalling of evidence and negotiation. Early strategy is therefore generally critical.
Penalties and Risk Exposure
The risk in tax matters is not limited to back tax. It can also extend to penalties and interest, which in some cases can be significant. Common risks include:
- Back tax (recovery of historical tax);
- Penalties, based on negligence or intentional conduct;
- Interest, accruing over time;
- In more serious cases, further legal consequences.
For example, where a tax arrangement is treated as unreasonable, the ATO may not only seek back tax but also adjust multiple years and impose penalties.
The focus of tax disputes is therefore generally not just “whether tax must be paid”, but how to manage the overall risk exposure.
Tax Planning & Risk Management
Beyond dispute resolution, an important part of tax legal services is up-front planning. Sensible tax arrangements can help a business optimise its structure within the law and reduce the likelihood of future disputes.
In practice, tax planning typically involves:
- Corporate structure design (such as companies, trusts or other arrangements);
- The way income and profit are distributed;
- Transaction arrangements (such as asset sales or restructuring);
- Cross-border business structures;
- Risk management and compliance mechanisms.
It is important to note that tax planning is not the same as “reducing tax”. The objective is to put in place reasonable arrangements within what the law permits.
Overly aggressive structures or arrangements lacking commercial substance can be challenged in the future.
Common Tax Risks
In practice, we frequently see issues of the following kinds:
- Long-standing errors in the way returns have been lodged that have not been picked up;
- Corporate structures that have not been adjusted to keep pace with the business;
- Inconsistent or incorrect GST treatment;
- Misunderstandings about deduction claims;
- Failure to consider the tax implications of transactions or investments in advance.
These issues share a common feature: the impact is not obvious in the early stages but emerges in concentrated form during reviews or disputes.
Should You Seek Advice?
Tax issues are often time-sensitive. Obtaining advice early is particularly important in the following situations:
- Receipt of an ATO review or investigation notice;
- An assessment requiring back tax or imposing penalties;
- A significant transaction or restructuring is being planned;
- There is uncertainty about whether existing tax arrangements are compliant;
- The matter involves cross-border income or complex commercial arrangements.
The earlier advice is sought, the more scope there typically is to adjust the strategy and manage the risk.

Frequently Asked Questions
If I receive an ATO notice, does that mean the company’s tax position is already in trouble?
Not necessarily, but it usually means the ATO has begun paying attention to a particular issue. Many clients, on first receiving a letter from the ATO, treat it as a routine notice. In practice, the substance of the notice is the key issue. The notice may relate to:
A request to verify information
A tax audit
Questions about historical lodgements
A request for back tax, payment of penalties or further explanation
At this stage, the question is rarely just “should I respond?”. It is how to respond, how to manage the scope of the response, and whether the matter may extend to multiple financial years or wider tax arrangements. NS Legal can review the ATO notice, assess the current level of risk and develop a more measured response strategy.
The ATO has asked the company to pay back tax, can I still object?
In some cases, yes. A request from the ATO for back tax does not necessarily mean the decision is correct or unable to be challenged. The position generally needs to be analysed further:
The basis on which the ATO has made its adjustment
Whether there is a dispute on the legal interpretation
Whether the underlying facts have been fully assessed
Whether there is scope to lodge a formal objection or to seek review
Whether the time limits in the relevant process have been preserved
Some tax disputes can be resolved by submitting further explanations or documents, or by lodging a formal objection. Others require a more systematic legal response. In tax dispute matters, NS Legal can help assess your current legal position and the practical next steps available.
Should I go to an accountant or a tax lawyer for a tax issue?
It depends on the nature of the issue. For routine return preparation, lodgement or ordinary tax record-keeping, accountants are usually an important source of support. Once an issue involves:
An ATO review or investigation
A tax dispute
Back tax or penalties
Corporate structure design
Significant transactions or restructuring
Legal risk or disputes over the interpretation of tax law
it is generally no longer purely a matter of accounting treatment, but one involving legal judgement, procedural strategy and overall risk management
Many complex tax matters in fact require lawyers and accountants to work together. NS Legal can help assess what level of support is more appropriate for your circumstances.
Should I think about tax before a restructuring, investment or sale of business?
It is generally advisable to think about tax in advance, rather than waiting until the transaction is close to completion. Many commercial clients first focus on:
Whether the deal can be done;
Whether the price is reasonable;
Whether the commercial terms have been agreed.
Tax effects, however, can directly change the outcome of the transaction, for example:
Whether GST applies;
Whether capital gains tax will arise;
Whether the current corporate structure is suited to the transaction;
Whether the income distribution arrangements give rise to long-term tax risk (including potential Division 7A issues);
Whether certain arrangements may later be challenged by the ATO.
NS Legal can take the transaction arrangements, the corporate structure and the relevant legal risks into account and help identify key tax issues earlier, so that you are not forced to make changes late in the deal.
