A sales manager's attempt to deduct a home "IT lab" has failed at the Administrative Review Tribunal, with the decision providing a timely reminder about the limits of work-related deductions.

In Hartley and Commissioner of Taxation [2026] ARTA 1590, handed down on 12 August 2026, the Tribunal upheld the refusal of approximately $31,870 in disputed deductions and confirmed a $4,778 administrative penalty for recklessness.

For taxpayers preparing 2025–26 returns, the case highlights the importance of showing a clear connection between an expense and the duties that actually produce employment income.

Inside the Home IT Lab Claim

The dispute concerned the 2022 income year, when the taxpayer worked as a sales manager for a communications-technology business.

He claimed deductions connected with a home IT laboratory, computer equipment, software, subscriptions, research activities, self-education and other technology-related expenses.

The original claim was approximately $40,664.

By the time the matter reached the Tribunal, around $31,870 remained in dispute.

The largest amounts included approximately $20,437 in capital allowance claims for computers and storage equipment and around $7,068 for computer repairs and consumables.

Other disputed amounts included software, computing subscriptions and additional subscription expenses.

Why the Connection to Employment Matters

The central issue was whether the expenses had a sufficient connection with the taxpayer's income-producing employment duties.

For an employee expense to be deductible, it generally needs to be incurred in the course of earning assessable income.

An expense can be useful to a person's career without necessarily satisfying that requirement.

The Tribunal found that the taxpayer's home technology activities were more closely connected with a broader interest in information technology and maintaining or developing professional skills than with the specific duties of the sales role.

This distinction is important.

A computer, server or software subscription may improve general knowledge or future employment prospects, but that does not automatically make the cost deductible against income from a current job.

Professionally Useful Does Not Automatically Mean Deductible

The decision illustrates the difference between an expense being professionally useful and being incurred in earning current employment income.

Technology purchased for experimentation, research or skill development may have professional value.

However, where those activities are not sufficiently connected to the taxpayer's existing duties, the deduction can fail.

The same principle can apply to subscriptions, training, specialist equipment and other expenses.

The relevant question is not simply whether an expense makes a person better at their profession.

The stronger question is whether the expenditure has the required connection to the income-producing activities of the current role.

Personal Use Also Needs to Be Considered

Where equipment has both work and private use, only the work-related portion can generally be claimed.

This means taxpayers may need to apportion the cost of laptops, tablets, monitors, internet services or other technology.

For example, if a laptop is used 60% for work and 40% privately, only the work-related portion of its decline in value would generally be deductible.

Subscriptions can create similar issues.

A subscription with substantial private or entertainment content may be difficult to claim unless there is a clear and supportable work-related component.

Accurate records become particularly important where an expense has mixed use.

The $4,778 Recklessness Penalty

The Tribunal also upheld a $4,778 administrative penalty imposed on the basis of recklessness.

This is important because a denied deduction can lead to more than repayment of the resulting tax shortfall.

Under the administrative penalty framework, different penalty rates can apply depending on the taxpayer's conduct.

A failure to take reasonable care generally attracts a lower base penalty than recklessness.

Recklessness generally carries a base penalty equal to 50% of the relevant tax shortfall, compared with 25% for failing to take reasonable care.

Interest charges can also apply to unpaid tax amounts.

The penalty element of the case therefore reinforces the importance of having a reasonable basis for large or unusual claims.

What the Case Means for Work-From-Home Claims

The case was not primarily about the fixed-rate work-from-home method.

However, its reasoning is relevant to employees claiming home-office and technology costs.

The key principle remains that expenses must be connected with earning assessable income.

For 2025–26, eligible taxpayers using the fixed-rate method can claim 70 cents for each hour worked from home.

The fixed rate is designed to cover certain running costs, including electricity, internet, phone usage and stationery.

Separate deductions may still be available for the decline in value of assets such as computers, office furniture and other equipment.

However, those separate deductions generally need to be limited to the work-related use of the asset.

Record Keeping Remains Essential

Taxpayers need records supporting both the expense and its connection with work.

For work-from-home claims, that can include records of actual hours worked from home.

For equipment, records may include purchase invoices, dates of acquisition, work-use percentages and depreciation calculations.

Where an asset has private use, taxpayers should have a reasonable basis for the work-related percentage claimed.

Large technology claims may attract closer attention where the equipment appears unusual for the employee's occupation or where the connection with current duties is unclear.

A Hypothetical Work-From-Home Example

Consider Priya, an employee who works from home two days each week.

She works eight hours on each home day for 46 weeks during the year.

That produces:

736 hours × $0.70 = $515.20.

Her fixed-rate work-from-home claim would therefore be $515.20, assuming the required records are maintained.

Priya also purchases a $2,000 laptop.

Assume the laptop is used 60% for work and is held for the entire year.

Using a simplified prime-cost example with an assumed two-year effective life:

$2,000 × 50% × 60% = $600.

The work-related decline in value would therefore be $600 under those assumptions.

Now assume Priya also buys a separate home server purely to experiment with technology unrelated to her current job.

That expense would be much harder to support because its connection with earning her employment income would be weaker.

Future Rules From 2026–27

The work-related deduction framework changes from the 2026–27 income year.

Eligible workers will be able to access a standard deduction of up to $1,000 for certain work-related expenses under the new rules.

The standard deduction does not apply to 2025–26 returns currently being prepared.

The first claims under the new framework will arise in returns lodged after the end of the 2026–27 income year.

Where a taxpayer claims work-related expenses exceeding the standard amount, stronger substantiation requirements can apply.

This means taxpayers with large technology or home-office costs will still need to demonstrate the connection between those expenses and their employment.

Large Claims Need Stronger Support

The larger and less conventional a deduction becomes, the more important supporting evidence can be.

An employee claiming a normal laptop partly used for work presents a different factual situation from someone claiming a substantial home IT laboratory containing multiple servers, storage systems and specialist equipment.

The amount alone does not determine whether a deduction is valid.

However, unusual claims can make the connection with the taxpayer's income-producing duties more important to demonstrate.

Employment duties, job descriptions, usage records and evidence of how the equipment is used can all become relevant.

Key Dates for Tax Time 2026

Taxpayers lodging their own 2025–26 return generally have until 31 October 2026.

Because 31 October falls on a Saturday in 2026, the applicable weekend rules can affect the practical lodgment date.

Taxpayers using registered tax agents can have different lodgment deadlines depending on the relevant lodgment program and when they become clients.

The important point for work-related claims is to ensure supporting records are available before the return is lodged.

The new $1,000 standard deduction rules do not apply until the 2026–27 income year.

What Employees Should Take From the Decision

The decision does not mean employees cannot claim technology used at home.

The stronger lesson is that the equipment must have a sufficient connection with the taxpayer's current income-producing activities.

A laptop required for regular employment duties may satisfy that test.

A specialist server used mainly for personal experimentation, future career development or general professional interest may not.

Taxpayers should also separate private use, maintain records and avoid assuming that an expense is deductible merely because it relates broadly to their profession.
