The Burden of Proof in Taxation
Disputes: Does Section 170 or Part
IVA of the Income Tax Assessment
Act 1936 (Cth) Offend the Rule of
Law?
Max Bruce*
Abstract
For the purposes of assessing tax, section 170 of the Income Tax Assessment Act 1936 (Cth) permits
the Commissioner to determine that the taxpayer has committed fraud or evasion. The taxpayer
then bears the onus of showing that they have not. There is no requirement that the Commissioner
show that such determination is correct, nor to support it with evidence. The Commissioner may, if
they wish, do nothing more than put the taxpayer to proof by tendering their assessment as
evidence. This article sets out in detail how the reversal of the onus of proof in cases arising from the
Commissioner’s determination of fraud or evasion offends the principle of procedural fairness, as
well as the principles of certainty and prospectivity. This paper also extendsthat analysis to disputes
arising out of the commissioner’s determination of tax avoidance under Part IVA of the Income Tax
Assessment Act 1936 (Cth). This paper further considers whether general administrative law
principles, in particular the Briginshaw Principle, may obviate some of the concerns regarding the
reversal of the onus of proof. It is contended that the reversal of the onus of proof in cases arising
out of the Commissioner’s determination of fraud or evasion under section 170 and tax avoi dance
under Part IVA significantly offend fundamental tenets of the rule of law, namely, theprinciples of
procedural fairness, certainty and prospectivity. It is further contended that requiring the Com-
missioner to adduce evidence to support the opinion or allowing the Commissioner’s determi-
nation to be judicially examined would obviate the offence to the rule of law.

I Introduction
In October of 2021, the House of Representatives Standing Committee on Tax and Revenue re-
leased its Report on the 2018–19 Commissioner of Taxation Annual Report.
1
The Committee’s
Report recommended, inter alia, that the onus of proof should lie with the Commissioner in
establishing fraud or evasion for the purpose of assessing tax under section 170 of the Income Tax
Assessment Act 1936 (Cth); as indeed had been recommended in the Committee’s previous
2015 Report on Tax Disputes.
2
These reports argue that placing the burden of proof on the taxpayer in such circumstances significantly
undermines the application of the rule of law and, in particular, the principle of procedural fairness. While
there are a number of laws that place the onus of proof on the party defending a claim made against them,
and several justifications given for this,
3
these reports suggest that the affront to the principle of procedural
fairness is particularly severe in respect of the Commissioner’s determination of fraud or evasion. Indeed,
practitioners in the field of taxation are habituated to the inequality of power inherent in the review process.
However, as Russell notes, were a candid description of the review process given to a lawyer or public
servant in any other area of public administration, the response would range from ‘disbelief to outright horror
at the extent of the power imbalance in favour of the ATO’.

This paper expands on the arguments advanced in the Committee’s reports and sets out in detail
how the reversal of the onus of proof in cases arising from the Commissioner’s determination of
fraud or evasion offends the principle of procedural fairness, as well as the principles of certainty
and prospectivity. This paper also extends that analysis to disputes arising out of the commissioner’s
determination of tax avoidance.
This paper further considers whether general administrative law principles, in particular the Bri-
ginshaw Principle, may obviate some of the concerns regarding the reversal of the onus of proof.
It is contended that the reversal of the onus of proof in cases arising out of the Commissioner’sde-
termination of fraud or evasion under section 170 and tax avoidance under Part IVA significantly offend
fundamental tenets of the rule of law, namely, the principles of procedural fairness, certainty and pro-
spectivity. It is furthercontended that requiring the Commissioner to adduce evidence to support the opinion
or allowing the Commissioner’s determination to be judicially examined would obviate the offence to the
rule of law.
II How the Burden of Proof Applies in Taxation Law Disputes
In criminal trials, the prosecution bears the burden of proof beyond all reasonable doubts of the accused’s
guilt. Whereas, in a civil claim, while the burden of proof on the balance of probabilities will generally lie
