Note: Entry of orders is dealt with in Rule 39.32 of the Federal Court Rules 2011.
The significance of the distinction between substantiation and qualification for deduction
(a) it must qualify as a deduction under some provision of this Act outside this Division; and
(b) you need to substantiate it by getting written evidence.
Subdivision 900-E tells you about the evidence you need.
(a) it must qualify as a deduction under some provision of this Act outside this Division; and
(b) you need to substantiate it by getting written evidence.
Subdivision 900-E tells you about the evidence you need.
Each of the following sections has a set of rules for a particular way of getting written evidence to substantiate a deduction. Which ones you can use depends on the type of expense. You only need to use one set of rules to support an expense.
A work expense is a loss or outgoing you incur in producing your salary or wages.
Travel allowance expenses count as *work expenses. A travel allowance expense is a loss or outgoing you incur for travel that is covered by a *travel allowance. The loss or outgoing must:
(a) be for accommodation or for food or drink; or
(b) be incidental to the travel.
an allowance your employer pays or is to pay to you to cover losses or outgoings:
(a) that you incur for travel away from your ordinary residence that you undertake in the course of your duties as an employee; and
(b) that are losses or outgoings for accommodation or for food or drink, or are incidental to the travel.
An exception for domestic travel allowance expenses
Exception for domestic travel allowance expenses
(1) You can deduct a *travel allowance expense for travel within Australia without getting written evidence or keeping travel records if the Commissioner considers reasonable the total of the losses or outgoings you claim for travel covered by the allowance.
(2) In deciding whether the total of the losses or outgoings you claim is reasonable, the Commissioner must take into account the total of the losses or outgoings of the following kinds that it would be reasonable for you to incur for the travel:
(a) accommodation;
(b) food or drink;
(c) losses or outgoings incidental to the travel.
This Determination sets out the amounts that the Commissioner considers are reasonable (reasonable amounts) for the substantiation exception in Subdivision 900‑B of ... ITAA 1997 for the 2020-21 income year in relation to claims made by employees for:
- ...
- domestic travel expenses - for accommodation, food and drink, and incidentals when travelling away from home overnight for work (particular reasonable amounts are given for employee truck drivers, office holders covered by the Remuneration Tribunal and Federal Members of Parliament) and
- ...
- you spent the money in performing your work duties (for example, in travelling away from home overnight on a work trip)
- how you worked out your claim (for example, you kept a diary)
- you spent the money yourself (for example, using your credit card statement or other banking records) and were not reimbursed (for example, a letter from your employer), and
- you correctly declared your allowance as income in your tax return.
Not doing something necessary to follow the rules in this Division does not affect your right to a deduction if the nature and quality of the evidence you have to substantiate your claim satisfies the Commissioner:
(a) that you incurred the expense; and
(b) that you are entitled to deduct the amount you claim.
Not doing something necessary to follow the rules in this Division does not affect your right to deduct an amount if the only reason was that you had a reasonable expectation that you would not need to do it in order to be able to deduct that amount.
Effect of compliance with substantiation upon qualification for deduction
The main provisions of relevance in the present case
(1) section 8-1(1), being the qualifying provision for the deduction; and
(2) section 900-50, which provided an exception from substantiation if the Commissioner consider reasonable the total claim for travel covered by an allowance.
Findings based upon the credibility of Mr Shaw's account
(1) Mr Shaw is generally away from home for six days every week and he sleeps in his truck;
(2) Mr Shaw does spend some amounts on food at roadhouses and supermarkets during his trips;
(3) Mr Shaw uses cash to pay for that food;
(4) to ensure that he does not have to rely on food outlets given the remote areas he drives through, Mr Shaw and his wife, Ms Fisher, ensure that he has sufficient food in his truck to meet his needs;
(5) the habit is for a 'big shop' to be done on a Monday or sometimes on a Sunday to ensure his truck is fully stocked each week before he goes on the road on a Monday;
(6) generally, Mr Shaw buys the food or he transfers funds to Ms Fisher and she buys the food;
(7) sometimes, Ms Fisher acquires additional food as part of the big shop or during the week when Mr Shaw is away. This is stored in the freezer at home so Mr Shaw can load it in his truck for the next week;
(8) 'Mr Shaw candidly acknowledged ... that he does not ask, and it is possible that Ms Fisher uses some of the funds he transfers to her for herself or the household'. This acknowledgement was to his credit. Mr Shaw described this as potentially $50 here and there but he was not certain. He also said Ms Fisher knows that the funds he transfers to her are for the big shop and for his meals while on the road as he told her as much';
(9) 'Mr Shaw cannot recall specific shops from five years ago. He also thought he would not have to substantiate specifically what was purchased, as a result of [the Determination]'; and
(10) 'Mr Shaw said he spends more than $105.75 (the maximum reasonable daily amount) on food during his trips away, but only claims that capped amount. His tax agent told him that he did not need to substantiate his expenses if he claimed the lower figure in [the Determination], which was lower than his actual expenditure'.
In this case, the Commissioner accepts that food and drink expenses incurred by Mr Shaw while away from home on a work journey would be deductible. However, paragraph 8-1(2)(b) of the ITAA 1997 provides that a loss or outgoing of a private or domestic nature cannot be deducted. This is the Commissioner's complaint in this case.
... the Commissioner says that if a travel allowance is received, expenses must be incurred and if the claim is no more than the reasonable amount no substantiation is required.
The Tribunal's excursus concerning unattractive aspects of the case
Before commencing with legal analysis, the Tribunal records that both parties in this matter presented aspects of their respective cases in an unattractive manner. I comment on those features below.
(emphasis added)
The Commissioner considers issues like living expenses (including grocery expenditure) in an array of different contexts, and there is available data of average spends: for example 2 September 2024 Average Grocery Bill | Australian Living Costs - Canstar Blue . The Commissioner could have investigated and considered costs at the outlets on Mr Shaw's route in the Relevant Year.
Alongside the areas of investigation noted above, taking into account the evidence of Mr Shaw, the Commissioner could have taken the payments made to Ms Fisher on Saturdays, Sundays and Mondays as for the purchase of food for the truck, ignored the rest of the transfers made by Mr Shaw to Ms Fisher, and reduced each of those payments received by Ms Fisher by $50 to allow for potential private expenditure. That would overstate that potential private expenditure in all likelihood and understate food expenditure (particularly by ignoring all other transfers to Ms Fisher). An estimated amount of expenditure using the cash in the truck could have been considered - for example $300-$500. Then all small expenditure at service stations, roadhouses and food outlets on the bank statements added up for each trip away. When that sort of method is followed it can be seen that Mr Shaw spends above the maximum reasonable daily allowance. The Commissioner may have considered requesting (formally if necessary) a short period of full substantiation currently to cross check before determining the question.
The Tribunal believes the Commissioner could have determined a methodology from the evidence provided. The Tribunal appreciates that the difficulty for Mr Shaw is that without full substantiation, which he thought was not required, it seemed difficult to convince the Commissioner as to an apportionment methodology.
(footnotes omitted)
Each taxpayer can decide between maintaining fewer records and limiting a claim to the reasonable amount, which in some cases may be lower than the amount actually incurred or keeping written evidence and claiming the full amount of deductible expenses incurred, which may be higher than the reasonable amount.
It is what is claimed that is important when determining issues of substantiation, not what could be claimed. It is perfectly legitimate to limit the claim, to limit the paperwork.
(original emphasis, footnotes omitted)
My assessment of those submissions [by the tax agent for Mr Shaw] was that he was saying that while Mr Shaw did incur the expenditure, [the Determination] provided authorisation for the standard deduction approach that had been adopted. [The Determination] is about substantiation, and it does not provide a one-off set deduction for truck drivers and there is no statutory provision providing for that. [The Determination] also says as much.
I also comment on [the tax agent for Mr Shaw's] submission that "[i]t is not open to an officer of the Australian Tax[ation] Office to determine a reasonable amount different to the published yearly Taxation Determinations." This is a fundamental misunderstanding of what the Commissioner has done in this case. The Commissioner is assessing what it believes can be demonstrated as having been incurred; it is not changing its Taxation Determination, nor the reasonable amount set in [the Determination]. This kind of submission is reflective of an idea that there was some sort of automatic deduction available to truck drivers which is not the position.
(footnote omitted)
The Commissioner is required to do two things. The Commissioner is required to both say what a reasonable amount is and determine whether the expenditure has really been incurred. As is described below, the Commissioner tried to signal that balance in [the Determination]. I suspect the Commissioner will particularly want to consider whether the expenditure has been actually incurred by a truck driver if the maximum reasonable daily amount in [the Determination] (or the equivalent annual determination) is consistently claimed by a taxpayer. In testing that issue, the Commissioner needs to act sensibly, and consider the substantiation provided by the taxpayer taking into account what was said in [the Determination] and section 900-200 of ITAA 1997 - it is a balancing exercise for the Commissioner.
Whether Mr Shaw incurred the expenses claimed in the Relevant Year in gaining or producing his assessable income
(original emphasis)
The Commissioner is correct that amounts must be incurred in gaining or producing his assessable income before an expense can be claimed under section 8-1 of the ITAA 1997. The Commissioner's complaint is that Mr Shaw has not been able to demonstrate that his claim is for entirely work-related expenses, as opposed to food acquired for private purposes.
[The tax agent for Mr Shaw] suggested that what the Commissioner was really seeking to do was walk back [the Determination]. I agree with aspects of [the tax agent's] submissions. I do not believe the Commissioner has the balance right in this case, taking [the Determination] and section 900-200 of the ITAA 1997 into account. Mr Shaw had a reasonable expectation that [the Determination] would be applicable.
The Tribunal [in Duncan] found there was no reliable way to estimate what was private expenditure and what was not. The difference in this case is we do have a way to estimate what is private expenditure and what is not, because of Mr Shaw's sworn evidence.
The Tribunal has determined that Mr Shaw incurred the disputed expenses in gaining or producing his assessable income. The Tribunal does not agree with the Commissioner that there is an insufficient linkage between the expenditure on bank statements and Mr Shaw's work. Mr Shaw's evidence was credible and provided that link. Mr Shaw's evidence also gave a broad mechanism for apportionment and that basis could have covered many of the Commissioner's concerns. To that extent, the Tribunal agrees with [the tax agent for Mr Shaw].
I find on the balance of probabilities that Mr Shaw incurred the claimed expenditure, and I find that Mr Shaw has met his burden of proof.
(footnote omitted)
See footnotes 44 and 45 above. As an example of how the Commissioner's concerns could have been covered, monetary transfers to Ms Fisher could have been disregarded unless they were made close to the day of the 'big shop' (a Sunday or Monday).
Whether Mr Shaw is required to substantiate his expenses or is entitled to rely upon an exception from substantiation under section 900-50 of the ITAA 1997.
Even if I am wrong about any aspect of the analysis in paragraph 52, I also find that Mr Shaw had a reasonable expectation that [the Determination] would apply due to the advice received from his tax agent. I find that section 900-200 of the ITAA 1997 would have applied to relieve Mr Shaw from the obligation to substantiate his meal expenses in any event.
The issues raised by the Commissioner's grounds of appeal
(1) In concluding that Mr Shaw had incurred the claimed expenditure, how did the Tribunal approach the issue of apportionment, especially having regard to Mr Shaw's evidence about the possibility that, when Ms Fisher did the big shop, she used some of the funds Mr Shaw transferred to her for the big shop for herself or the household (and therefore not on food for Mr Shaw's meals when travelling)?
(2) In its reasoning concerning Footnotes 44 and 45, did the Tribunal, in effect, reverse the onus of proof and require the Commissioner to prove that the meal expenses were not deductible by pursuing the 'areas of investigation' in Footnotes 44 and 45 (Ground 1)?
(3) Properly construed, does the test for deductibility in s 8-1(1) of the ITAA97 involve the application of a general 'reasonableness' standard and, if not, did the Tribunal apply a general 'reasonableness' standard in reaching its conclusion that the meal expenses were deductible (Ground 2)?
(4) Did the Tribunal find that, for the purpose of apportioning private expenditure under s 8-1(2)(b) of the ITAA97, the potential private expenditure by Ms Fisher from the big shop transfers was limited to $50 per transfer and, if so, was the finding made in the absence of evidence or by drawing an inference that was not open on the facts found (Ground 3)?
(5) Did the Tribunal find that that Mr Shaw had established a broad mechanism for apportionment and, if so, was the finding made in the absence of evidence or by drawing an inference that was not open on the facts found (Ground 4)?
(6) Did the Tribunal find that a 'reasonable expectation' within the meaning of s 900-200 of the ITAA97 relieved Mr Shaw of the obligation to establish that the meal expenses were incurred within the meaning of s 8-1(1) and, if so, was that a misconstruction of s 8‑1(1) and did the Tribunal act on that misconstruction in concluding that Mr Shaw incurred the meal expenses (Ground 6)?
(7) Did the Tribunal misconstrue s 900-200 in making the alternative finding that s 900‑200 applied to relieve Mr Shaw of his obligation to substantiate his meal expenses on the basis of advice provided by his tax agent that the Tribunal found to be 'not supportable at law' (Ground 5)?
(8) Did the Tribunal incorporate its views as to s 900-200, incurred within the meaning of s 8-1(1) of the ITAA97 and, if so, were those views informed by a misconstruction of s 900-200 to the effect that there could be a 'reasonable expectation' based on the views of a tax agent that the Tribunal found to be 'not supportable at law' (Ground 7)?
Issue (1): How did the Tribunal approach the issue of apportionment?
Specifically, in concluding that Mr Shaw had incurred the claimed expenditure, how did the Tribunal approach the issue of apportionment, especially having regard to Mr Shaw's evidence about the possibility that, when Ms Fisher did the big shop, she used some of the funds Mr Shaw transferred to her for the big shop for herself or the household (and therefore not on food for Mr Shaw's meals when travelling)?
Mr Shaw's evidence also gave a broad mechanism for apportionment and that basis could have covered many of the Commissioner's concerns.
Issue (2): Did the Tribunal reverse the onus of proof?
Specifically, in its reasoning concerning Footnotes 44 and 45, did the Tribunal, in effect, reverse the onus of proof and require the Commissioner to prove that the meal expenses were not deductible by pursuing the 'areas of investigation' in Footnotes 44 and 45 (Ground 1)?
Issue (3): Did the Tribunal apply a general reasonableness standard?
Issue (4): Did the Tribunal reach a conclusion on apportionment in the absence of evidence?
Specifically, did the Tribunal find that, for the purpose of apportioning private expenditure under s 8-1(2)(b) of the ITAA97, the potential private expenditure by Ms Fisher from the big shop transfers was limited to $50 per transfer and, if so, was the finding made in the absence of evidence or by drawing an inference that was not open on the facts found (Ground 3)?
Would you agree that generally, Ms Fisher's not purchasing the food and drink only for you? The money you're transferring to her is for her use?---I don't ask to see a receipt on what she's bought me and how much she's spent. If I give her $500 to go down to Coles to buy me stuff and she's spent 320 and then bought herself something, I don't know. I don't ask her what she spends her money on. I just give her money and she just buys stuff. That's it.
No, that's fine, Mr Shaw. I was just trying to understand - you're purchasing food for your work trips yourself?---Yes.
The money that you're transferring to Ms Fisher is for her use. She can spend it on whatever; she's not only spending that money for you - for your work trips?---I'm sending it to her to buy me stuff. If she wants to buy something for herself that's $50 or whatever, then she can go and buy it.
When you get her funds - I appreciate your honesty in saying that if she wants to spend $50 here and there on herself that you would understand that. I appreciate that honesty. That's a really good, honest answer. I suppose I want to understand - she knows, does she, when you give her funds, that's for her to go and get your stuff so that you can have that stuff on the road or that's for her to go and get your stuff so it can be thawed in the freezer at home so you can take it eventually when you go on the road. Is that how you present the transfer of funds to her?
Yes. Like, on my statement, sometimes you'll see I've transferred $600. Sometimes even more. And that's because she's actually wanted something and I've given her the money to go get it. That's why some of the ones that I've got on my statements are a lot higher than $300 or $400.
Issue (5): Did the Tribunal err as to the broad mechanism for apportionment?
Specifically, did the Tribunal find that that Mr Shaw had established a broad mechanism for apportionment and, if so, was the finding made in the absence of evidence or by drawing an inference that was not open on the facts found (Ground 4)?
Issue (6): What did the Tribunal conclude concerning the application of s 900-200?
Specifically, did the Tribunal find that a 'reasonable expectation' within the meaning of s 900-200 of the ITAA97 relieved Mr Shaw of the obligation to establish that the meal expenses were incurred within the meaning of s 8-1(1) and, if so, was that a misconstruction of s 8-1(1) and did the Tribunal act on that misconstruction in concluding that Mr Shaw incurred the meal expenses (Ground 6)?
Issue (7): Does the concept of 'reasonable expectation' used in s 900-200 exclude an instance where the taxpayer acts on incorrect advice from a tax agent?
Specifically, did the Tribunal misconstrue s 900-200 in making the alternative finding that s 900-200 applied to relieve Mr Shaw of his obligation to substantiate his meal expenses on the basis of advice provided by his tax agent that the Tribunal found to be 'not supportable at law' gave rise to a 'reasonable expectation' (Ground 5)?
Specifically, did the Tribunal incorporate its views as to s 900-200, incurred within the meaning of s 8-1(1) of the ITAA97 and, if so, were those views informed by a misconstruction of s 900-200 to the effect that there could be a 'reasonable expectation' based on the views of a tax agent that the Tribunal found to be 'not supportable at law' (Ground 7)?
