The ATO isn't trying to catch you out. They're trying to decide whether they need to.
There's a misconception about the ATO's Justified Trust program that needs to be cleared up.
Many tax teams hear "Justified Trust" and think "audit." They brace for scrutiny. They get defensive. They treat it as an adversarial process where the ATO is looking for errors and the tax team is trying to avoid being caught.
This misses the point entirely.
Justified Trust isn't about catching mistakes. It's about the ATO determining whether it can trust that your tax outcomes are right — without needing to audit every line. It's a relationship framework, not an enforcement action.
Think of it like a statutory audit. When external auditors test your internal controls and find them reliable, they reduce their substantive testing — less sampling, less detailed inspection, less time spent verifying individual transactions. The controls give them confidence in the numbers without needing to check every line. The ATO's Justified Trust program works on the same principle. If your tax governance controls are demonstrably sound, the ATO can place greater reliance on your reported tax outcomes. The engagement becomes lighter-touch. The scrutiny reduces. The relationship shifts from verification to confidence.
And the difference between a tax function that earns that trust and one that doesn't? It's not about having the right answers. It's about having the right systems.
THE FOUR PILLARS
The ATO's Justified Trust framework focuses on four key areas for large taxpayers.
First: understanding your tax governance framework. Does your organisation have a tax risk management policy? Are there clear roles, responsibilities, and escalation paths? Is the board engaged on tax matters? The ATO wants to see that tax governance isn't just a document — it's a lived practice embedded in how you operate.
Second: understanding the tax outcomes in your income tax return. Can you reconcile your accounting profit to your taxable income, and explain the significant differences? The ATO wants to see that you understand your own numbers — not just that you've lodged a return, but that you can walk through the key judgements and positions.
Third: identifying and understanding significant and new transactions. When your group undertakes a material transaction — a restructure, an acquisition, a new financing arrangement — does your tax team identify the tax implications proactively? The ATO wants to see that you're ahead of the curve, not reacting to tax outcomes after the fact.
Fourth: understanding tax risks flagged by the ATO. When the ATO publishes guidance, taxpayer alerts, or practical compliance guidelines that affect your industry, does your tax team assess the relevance and respond? The ATO wants to see that you're engaged with the regulatory environment.
WHAT THIS MEANS IN PRACTICE
Strip away the framework language, and Justified Trust comes down to a simple question: could your tax team explain, clearly and with evidence, how every material number in your tax return was derived?
Not next week. Not after digging through spreadsheets. Now.
This requires three things: documented processes (how you do it), controlled workflows (that you actually follow the process), and complete traceability (proof that you followed it).
These three things are extraordinarily difficult to achieve when spreadsheets are your system of record. Now, it's worth being realistic: spreadsheets won't disappear entirely. Finance teams use them for their own workpapers, and that's fine. The issue isn't whether spreadsheets exist in the process — it's whether they're the system of record with no controls around them. Where spreadsheets are used, they should be properly structured so it's clear what the tax function has done to them, and they should interface cleanly with the core tax ledger via a controlled import process. That way you get the flexibility of spreadsheets where finance needs them, with the traceability and governance of a purpose-built system where it matters most.
THE ENGAGEMENT ITSELF
If you're a Top 100 or Top 1000 taxpayer — or increasingly, a Next 5000 taxpayer —you will have a Justified Trust engagement. The ATO's relationship manager willask to understand your tax governance, review your income tax reconciliation,and discuss significant transactions.
The engagement isn't a test you pass or fail. It's a conversation that determinesthe ATO's level of confidence in your tax function. Higher confidence meanslighter touch. Lower confidence means more scrutiny, more queries, more timespent responding instead of advising.
Every investment you make in your tax processes, your documentation, your systems,and your controls directly influences where you land on that spectrum.
THE STRATEGIC IMPERATIVE
Here's what the most sophisticated tax functions understand: Justified Trust isn't a compliance burden. It's a strategic opportunity.
A tax function that earns Justified Trust status operates with less ATO friction. Faster resolution of queries. More productive relationship with the ATO engagement team. Less time spent on defensive documentation and more time on proactive tax management.
And it starts with having systems and processes that make trust justified.
Not hoped for. Not assumed. Justified. With evidence, traceability, and confidence.
