ATO Rule Change Set to End a Popular Tax Break in 2026 — What Australians Need to Know

Quick answer: The ATO has tightened its rules around one of Australia's most commonly claimed deductions — the work-from-home fixed rate method. Millions of taxpayers who have relied on this straightforward shortcut to claim home office expenses now face stricter record-keeping requirements that, in practice, make the method far less convenient. If you're lodging a 2025–26 tax return, read this before you claim.

Tax time in Australia has long come with a certain ritual: millions of workers open their myGov accounts, click a few boxes, and claim a flat rate for working from home without keeping a single receipt. That era is quietly drawing to a close. The Australian Taxation Office has made changes that dramatically raise the evidentiary bar for the fixed rate method — the shortcut that made home office deductions almost effortless — and tax professionals are warning that many Australians will either miss out on legitimate deductions or get caught overclaiming.

Here is exactly what has changed, who is affected, and what steps you should take before lodging your return.

What Was the Popular Tax Break?

The "popular tax break" in question is the revised fixed rate method for work-from-home (WFH) deductions — sometimes still called the shortcut method by taxpayers who remember the COVID-era version.

During the pandemic, the ATO introduced a temporary 80 cents per hour shortcut rate. It was designed to be dead simple: log your hours, multiply by 80 cents, done. No need to apportion actual expenses like electricity, internet, or stationery between personal and work use.

That temporary shortcut was abolished in mid-2022. The ATO replaced it with a revised fixed rate of 67 cents per hour from 1 July 2022 onwards. The 67-cent rate covers:

Electricity and gas for heating, cooling, and lighting your workspace
Internet expenses (the work-related portion)
Mobile and home phone usage
Computer consumables such as printer ink and stationery
The decline in value of small items under $300

Under the original interpretation, many taxpayers were treating the 67-cent rate almost as loosely as the old 80-cent shortcut — minimal records, rough hour estimates, no real substantiation. The ATO has now made clear that this interpretation is incorrect, and it is actively reviewing claims.

What Has the ATO Actually Changed?

The ATO's updated guidance — which tax agents say is now being enforced more vigorously heading into the 2025–26 lodgement season — centres on two core obligations:

1. You Must Keep a Contemporaneous Record of Every Hour Worked

"Contemporaneous" is the key word here. It means records made at the time, not reconstructed later. The ATO explicitly states that a four-week representative diary is no longer acceptable as a substitute for a full-year log.

In practice, this means:

A diary, spreadsheet, or digital log showing actual hours worked from home for every day of the income year
Records saved progressively, not guessed at in June when you sit down to do your tax return
Employer documentation (such as a working-from-home arrangement letter or employment contract) confirming you are permitted to work from home

2. You Must Keep at Least One Record for Each Expense Type Covered by the Rate

Even though the 67-cent rate is meant to be a simplified method, the ATO now requires at least one representative document for each category of expense it covers — such as a utility bill, a phone bill, and an internet bill — to demonstrate that you actually incurred those costs.

This does not mean you need every bill for the year, but you do need evidence that the relevant expenses exist.

Important: If you cannot produce a contemporaneous hours log and supporting expense records, the ATO can and will disallow the entire work-from-home claim — not just reduce it.

Why Is This Change Significant?

On paper, these requirements seem reasonable. In practice, they represent a meaningful shift in the burden placed on ordinary taxpayers.

The ATO's own data has consistently shown that work-from-home deductions are among the most common claims in Australia, with millions of Australians lodging them each year. Research commissioned by industry groups has estimated that a large proportion of those claimants kept little to no contemporaneous records — they relied on the informal tolerance that existed around reconstructed logs.

That tolerance is now gone.

Tax professionals are warning clients that:

Many people who worked from home genuinely cannot prove their hours because they never kept a log at the time.
Pre-filled data from employers does not include hours — myGov will not automatically populate this field.
Audit activity around WFH claims is increasing, with the ATO using data-matching and employer payroll records to identify mismatches.

For context, consider how the numbers add up. An employee working from home three days a week for 48 weeks (allowing for holidays and leave) clocks roughly 720 hours annually. At 67 cents per hour, that is a deduction of $482.40 — which at a marginal tax rate of 32.5% (the rate that applies to income between $45,001 and $135,000 in 2025–26) saves approximately $157 in tax. Not life-changing, but meaningful — and the reason millions of Australians have bothered to claim it every year.

Without contemporaneous records, that $157 saving evaporates.

The Alternative: The Actual Cost Method

The ATO's other approved method for claiming WFH expenses is the actual cost method. This requires you to calculate the real, apportioned cost of each individual expense — electricity, internet, phone, stationery, and depreciation on equipment — and claim only the work-related percentage.

This method is more work, but it has several advantages:

It can produce a larger deduction if you work from home frequently or have high electricity costs
It is not subject to the same hours-log requirement (though you still need receipts and a reasonable apportionment basis)
It allows you to separately claim items like computer hardware, desks, and ergonomic chairs as depreciating assets — items that are excluded from the 67-cent rate

Worked Example: Actual Cost vs Fixed Rate

Assume Sarah is a project manager earning $95,000 who works from home four days a week (roughly 800 hours over the year). Her relevant annual costs are:

Expense	Annual Cost	Work-Related %	Work Deduction
Electricity (lighting, heating)	$2,400	30%	$720
Home internet	$1,200	50%	$600
Mobile phone	$900	40%	$360
Stationery and consumables	$180	100%	$180
Total — Actual Cost Method			$1,860

Under the fixed rate method: 800 hours × $0.67 = $536

The actual cost method yields $1,860 — more than three times the fixed rate result in this scenario. For higher earners or frequent home workers, the difference is even more pronounced.

Who Is Most Affected by This Change?

Employees Who Relied on Rough Hour Estimates

If you have been mentally tallying your WFH hours and entering a round number each June — say, "about 600 hours" — you are now at genuine risk. The ATO's definition of contemporaneous records does not accommodate retrospective estimates.

Sole Traders and Freelancers

Sole traders who claim a home office deduction as a business expense face similar scrutiny. The ATO is also tightening its approach to occupancy expenses (rent or mortgage interest apportioned to a dedicated home office), which have always required a more rigorous calculation and carry capital gains tax implications when you sell your home.

Taxpayers Using Tax Agents Who Relied on Client Self-Reporting

Many tax agents prepared returns based on the hours their clients told them they worked, often without questioning whether a contemporaneous log existed. Agents themselves are now at compliance risk if they lodge returns they have reason to believe are unsupported.

People Who Rarely Kept Receipts

If you have no utility bills, phone bills, or internet invoices on file, you may struggle to satisfy even the minimal documentary requirements under the fixed rate method. Most utility providers allow you to access at least 12 months of past bills through their online portals — do this now if you need to reconstruct your records.

What About the Occupancy Expenses Rule?

A separate but related concern that often surfaces in discussions about WFH tax breaks involves occupancy expenses — that is, claiming a portion of your rent or mortgage interest, rates, and insurance as a deduction because you use part of your home exclusively for work.

The ATO has long required that, to claim occupancy expenses, you must have a dedicated work area — a room or defined space used solely for income-producing activities, not the dining table that doubles as a desk.

More critically, if you own your home and claim occupancy expenses, you may lose part of your main residence CGT exemption — meaning when you eventually sell the property, a portion of the capital gain could be taxable. This is a significant and often overlooked trade-off.

Most employees working from home are advised not to claim occupancy expenses for this reason. The fixed rate and actual cost methods for running expenses (electricity, internet, phone) do not trigger the CGT issue — but occupancy expenses do.

Practical Steps to Protect Your 2025–26 Claim

If you have already been working from home this financial year and you want to claim a WFH deduction in your 2025–26 return, here is what you should do immediately:

Start a contemporaneous hours log today. Even if you cannot reconstruct every past day accurately, begin recording from now. Any portion of the year with a proper log is better than none.
Check whether your employer has issued any written WFH arrangement. A letter, email, or HR policy document confirming you are authorised to work from home is strong supporting evidence.
Retrieve your bills. Log in to your electricity, internet, and mobile provider accounts and download statements for the full financial year. Save them somewhere you will still be able to find them in three years (the ATO can audit returns up to five years after lodgement in cases of suspected fraud).
Consider whether the actual cost method gives you a better outcome. If your genuine WFH hours and household costs are high, run both calculations before deciding which method to use.
Talk to a registered tax agent. Given the increased compliance risk, a tax agent's guidance is worth paying for if you have a complex situation or high deductions.

What the ATO Has Said

The ATO has framed these changes as a matter of ensuring that deductions reflect genuine work-related costs. In public guidance, the ATO has reiterated that taxpayers are entitled to claim what they genuinely incur — but not more — and that record-keeping requirements are not optional.

The Tax Commissioner has also noted that the ATO's data-matching capability has expanded considerably, with payroll data, bank records, and third-party information now cross-referenced against lodged returns more systematically than in previous years.

The message is clear: the informal tolerance for approximate records is over.

The Bigger Picture: ATO Compliance Focus in 2026

The WFH crackdown is part of a broader ATO compliance posture heading into the 2025–26 lodgement season. Other areas receiving elevated scrutiny include:

Rental property deductions, particularly interest claims on loans where funds have been redrawn for personal use
Cryptocurrency capital gains, where the ATO has significantly expanded its data-matching with exchanges
Side hustle income from platforms like Airbnb, Uber, Airtasker, and similar gig economy providers
Inflated vehicle expense claims, particularly for work-related car use claimed under the cents-per-kilometre method

If you have deductions in any of these areas, the same advice applies: keep records, keep them contemporaneously, and ensure they match the claims you make.

Frequently Asked Questions

Can I still use the 67-cent fixed rate method for my 2025–26 return?

Yes — the 67-cent fixed rate method still exists and is still available. The change is not to the rate itself but to the record-keeping requirements needed to support the claim. You must have a contemporaneous log of actual hours worked from home and at least one document evidencing each type of expense covered by the rate.

What happens if the ATO audits my WFH claim and I can't produce records?

The ATO can disallow the entire deduction and may also apply administrative penalties for false or misleading statements. In cases of recklessness or intentional disregard of tax obligations, penalties can reach up to 75% of the tax shortfall. Interest also accrues on underpaid tax.

Does working from home one or two days a week still justify a claim?

Yes, provided you genuinely work from home and keep the required records. Even a modest number of hours adds up over a full year. The key is that the hours must be accurately recorded, not estimated after the fact.

Can I claim both the fixed rate method and depreciation on my home office equipment?

No — the 67-cent fixed rate already includes depreciation on items costing less than $300. However, for larger items (a computer, a desk, an ergonomic chair costing more than $300), you can claim the decline in value separately in addition to the fixed rate. Under the actual cost method, all equipment depreciation is claimed separately.

Is a dedicated home office room required to claim work-from-home deductions?

Not for the running expenses methods (fixed rate or actual cost). You can work from a dining table or lounge room and still claim electricity, internet, and phone costs. A dedicated room is only required if you want to also claim occupancy expenses such as rent or mortgage interest — and doing so has potential CGT consequences if you own your home.

What is the deadline for lodging my 2025–26 tax return?

If you lodge yourself through myGov, the deadline is 31 October 2026. If you use a registered tax agent, they typically have an extended lodgement schedule that can push your deadline to May 2027, provided you are on their books before 31 October 2026.
