A recent Tribunal decision highlights an important point for taxpayers claiming work-related computer deductions: using computer equipment for activities that benefit your employer does not automatically mean the related expenses are tax deductible.
Work-Related Computer Deductions: What Happened?
A recent Tribunal decision highlights an important issue for employees claiming work-related computer deductions: computer equipment and technology expenses are not automatically deductible simply because the activities benefit an employer.
In Hartley and Commissioner of Taxation [2026] ARTA 1590, the Tribunal considered whether a senior IT sales employee could claim substantial deductions for a home computer “lab”. Although the employee demonstrated that several projects undertaken at home were encouraged by and benefited his employer, the Tribunal ultimately denied the deductions in full.
The decision is a useful reminder that the connection between an expense and an employee’s actual income-earning duties is critical when determining whether a work-related deduction is available.
What Were the Work-Related Computer Deductions?
Mr Hartley was employed by Ericsson Australia as a Domain Sales Manager. He argued that his employment involved responsibilities beyond traditional sales activities. According to his evidence, his role also involved innovation, identifying new product opportunities and providing thought leadership within the industry.
During the 2022 income year, Mr Hartley claimed a substantial amount of work-related and capital allowance deductions associated with his home computer “lab”.
The total amount ultimately disputed before the Tribunal was $31,870. Most of the claim related to technology and computing expenses, including:
- Digital storage devices
- Computers
- Computer monitors
- Computer software
- Subscriptions to various computing services
The ATO denied the claims during its audit of Mr Hartley’s tax affairs. The taxpayer subsequently objected to the decision, but the deductions remained denied. The matter was then considered by the Tribunal.
The size and nature of the claim made the case particularly relevant for taxpayers who incur significant technology costs in connection with their employment.
The computer activities benefited the employer
Mr Hartley provided evidence of several projects undertaken using his home computer lab. These included:
- A network virtualisation project that was later developed and marketed by Ericsson;
- Cloud infrastructure work undertaken through an industry collaboration involving Ericsson; and
- Work on video interface technology that was featured in an Ericsson press release and later deployed in the business.
The Tribunal accepted that Mr Hartley had specialised expertise and that his senior role involved contributing to the development of marketable technologies.
However, this was not enough to establish that the expenses were deductible.
Why were the work-related computer deductions denied?
Despite that, the Tribunal denied the deductions in full. The reasoning turned on whose purpose the expenditure served:
- The activities weren’t required by the role. Ericsson neither mandated the work nor permitted Mr. Hartley to use company equipment to perform it.
- The taxpayer stood to keep the benefit. Evidence suggested the work was done at home partly so Mr. Hartley could retain ownership of any development if he left Ericsson.
- General professional interest isn’t enough. The Tribunal found the activities were closer to maintaining general professional standing and personal interest in IT than to discharging his actual employment duties.
Citing the High Court’s decision in Federal Commissioner of Taxation v Hatchett [1971] HCA 47, the Tribunal confirmed that employer encouragement of an activity without more does not convert it into a deductible work expense.
What Does the Hartley Case Mean for Work-Related Computer Deductions?
The ATO has repeatedly flagged work-related deductions as a compliance priority, and large or unusual claims attract particular scrutiny. Hartley is a useful reminder of where the line sits:
For businesses and taxpayers, it is not enough to demonstrate that:
- the equipment is used at home;
- the employer is aware of or encourages the activity;
- the employer benefits from the work; or
- the taxpayer uses the equipment to develop professional skills or maintain industry knowledge.
The nature of the taxpayer’s actual employment duties and the purpose for which the expenditure was incurred remain important considerations.
This is particularly relevant where an employee is claiming significant amounts for computers, monitors, storage equipment, software or online computing services.
Key takeaway for taxpayers
Before claiming a work-related computer deduction, taxpayers should consider whether the expense genuinely relates to their current income-producing duties rather than broader professional interests or personal projects.
The Hartley decision demonstrates that even substantial work that ultimately benefits an employer may not qualify for a deduction if it falls outside the employee’s actual employment responsibilities.
For significant claims, businesses and employees should retain appropriate records and carefully consider the connection between the expense, the employment duties and the income being earned.
Frequently Asked Questions
What was the outcome of Hartley and Commissioner of Taxation [2026] ARTA 1590?
The Administrative Review Tribunal upheld the ATO’s decision to deny Mr Hartley’s $31,870 claim for home computer “lab” expenses, finding the costs were not sufficiently connected to his actual employment duties.
Does employer encouragement make a work-related expense deductible?
No. The Tribunal confirmed that an employer encouraging or benefiting from an activity is not, on its own, enough to support a deduction. The expense must relate to the performance of the employee’s specific duties.
What case law did the Tribunal rely on?
The Tribunal cited Federal Commissioner of Taxation v Hatchett [1971] HCA 47, a longstanding authority on the limits of deductibility for self-education and work-related expenditure.
What should you take from this decision?
Before claiming large work-related deductions, test whether the expense was actually required to perform the client’s job not merely useful, encouraged, or professionally beneficial. Also consider who ultimately retains the benefit of any work product created.
Is the computer use directly connected to your employment duties?
A general professional interest may not be enough.
