A Private Binding Ruling from the ATO tells you how the tax law applies to your situation. But what if you disagree with the ruling? Here is what you can do.
A Private Binding Ruling (PBR) is one of the most useful, and occasionally most frustrating, tools available under Australian tax law. Used correctly, a PBR gives you certainty about how the ATO will treat a particular transaction or arrangement before you commit to it. But when the ATO’s ruling goes against you, the consequences can be financially devastating.
This article explains what a Private Binding Ruling is, how to apply for one, and, critically, what options you have if the ATO’s ruling is unfavourable.
A Private Binding Ruling is a formal written decision by the ATO setting out how it considers the tax law applies to a specific arrangement or transaction involving a specific taxpayer. Once issued, a PBR is legally binding on the ATO, meaning the ATO must apply the tax law in accordance with the ruling if you enter into the arrangement as described.
The key word is binding. A PBR is not mere guidance or a suggestion from the ATO. It is a commitment. If the ATO’s ruling is favourable to you, you can rely on it with confidence. If the ruling is unfavourable, however, it means the ATO has formally stated that it will tax the arrangement in a way that may be costly to you.
PBRs can be applied for in advance of a transaction, which is their most common and most valuable use, or after a transaction has been completed where there is uncertainty about its tax treatment. One caveat: the protection depends on accuracy. If the arrangement you actually carry out differs materially from the one described in the ruling, the ruling ceases to protect you.
If the ATO issues a PBR that you consider to be incorrect, either because the ATO has misapplied the law or misunderstood the facts, you have the right to object to the ruling. The objection is a written document lodged with the ATO, setting out clear grounds for why the ruling is wrong. The time limit is generally the later of 60 days after the ruling is given and the standard objection period for the relevant year’s assessment, 2 years for most individuals and small businesses, or 4 years for other taxpayers. Two further points matter. Once an assessment has issued for the period covered by the ruling, any challenge must generally be directed at the assessment rather than the ruling. And if the objection is disallowed, the matter can be taken to the Administrative Review Tribunal (which replaced the AAT on 14 October 2024) or the Federal Court within 60 days of the objection decision.
This is a situation where professional representation is essential. A successful objection to a PBR requires a compelling legal argument, not simply a disagreement with the outcome, and must engage directly with the ATO’s reasoning.
In one case handled by our office, a client had applied for a PBR on the question of her Australian tax residency. The ATO ruled that she was a foreign resident for tax purposes, a determination that, when applied to the sale of her Sydney home, generated a capital gains tax liability of over $350,000.
Our office lodged an objection to the PBR, arguing that the ATO had incorrectly applied the domicile test. After three months of detailed correspondence and the exchange of further evidence, the ATO accepted our argument and allowed the objection in full. The client’s CGT liability was reduced to nil.
This case demonstrates that PBRs, while binding, are not the final word. Where the ATO has made a legal error in a ruling, a well-argued objection can succeed.
The quality of the PBR you receive from the ATO is heavily influenced by the quality of the application you submit. A well-drafted PBR application sets out the facts clearly and completely, identifies the specific questions to be ruled on, and where appropriate, sets out the applicant’s own analysis of the relevant law.
A poorly drafted application, one that leaves out relevant facts or asks the wrong question, can result in a ruling that does not provide the certainty sought, or that inadvertently addresses a less favourable version of the arrangement than you intended.
