Home Office Setup Tax Deduction Australia 2026: What You Can Actually Claim

15 June 2026 · 9 min read

Quick Answer

In 2026, you can claim home office deductions using the ATO's fixed rate method (70 cents per hour) or the actual cost method. You can also deduct the cost of office furniture and equipment outright if each item costs under $20,000 under the instant asset write-off. Keep a record of hours worked and receipts for everything.

If you work from home — whether you're a sole trader, freelancer, or small business owner — the ATO lets you claim a portion of your home expenses as a tax deduction. But the rules have changed in recent years, and claiming incorrectly is one of the most common mistakes the ATO flags at tax time.

This guide covers exactly what you can claim in 2026, which method suits your situation, and how to handle the cost of setting up your home office — from the desk and chair to the monitor and internet connection. The rules apply whether you're running a full-time business or working from home a few days a week alongside a PAYG job.

One important note before we start: home office deductions are for the business-use portion of your expenses only. If you use your home office for both work and personal use, you can only claim the work-use percentage. Getting this split right matters — the ATO uses real-time data matching and will cross-check large deduction claims against your income.

The Two ATO-Approved Methods for 2026

The ATO offers two ways to calculate your home office running costs: the revised fixed rate method and the actual cost method. You use one or the other — you cannot mix them. The method you choose should reflect your actual situation and, ideally, maximise your deduction.

The revised fixed rate method gives you 70 cents per hour for every hour you work from home. This rate covers electricity, gas, internet, phone usage, and stationery. It does not cover depreciation of furniture or equipment — those are claimed separately on top of the 70 cents rate. To use this method, you must keep a record of your actual hours worked from home for the full income year. A timesheet, calendar, or digital log all count. The ATO removed the 4-week representative diary option — you now need a full-year record.

The actual cost method lets you claim the real dollar amount of each expense based on the percentage of your home used for work and the percentage of time it is used for work. This method requires more record-keeping but can produce a higher deduction if you have a dedicated home office that takes up a meaningful portion of your home's floor area. You'll need floor plan measurements, usage logs, and itemised receipts.

ATO tip: If you're unsure which method gives you a bigger deduction, calculate both before lodging. Most sole traders with a dedicated office room benefit more from the actual cost method.

At a glance — fixed rate vs actual cost:

Fixed rate: 70 cents/hour — covers electricity, gas, phone, internet, stationery
Actual cost: claim real expenses at your work-use percentage
Fixed rate does NOT cover furniture or equipment depreciation — claim those separately
Full-year hours log required for fixed rate (no 4-week diary shortcut)
Actual cost requires floor area calculation and itemised receipts

What Home Office Setup Costs Can You Deduct?

The cost of setting up your home office — the desk, chair, shelving, monitor, keyboard, printer, and any other equipment — is deductible. The key question is whether you claim the full cost upfront or depreciate it over time. This depends on the cost of each item and the instant asset write-off threshold that applies to your business.

For the 2025–26 income year, the instant asset write-off threshold for small businesses (aggregated turnover under $10 million) is $20,000 per asset. This means if your standing desk costs $1,800 or your external monitor costs $950, you can write the full amount off in the year you buy it — as long as the asset is installed and ready for use before 30 June 2026. Assets costing $20,000 or more are depreciated through the general small business pool at 15% in the first year and 30% in subsequent years.

For non-business individuals claiming as an employee working from home (not a sole trader), the threshold is different. Items costing $300 or less are written off immediately. Items over $300 are depreciated over their effective life as set by the ATO. Sole traders using their ABN have access to the more generous small business depreciation rules, which is one of the practical advantages of operating as a sole trader.

Important: If you use your laptop or phone for both work and personal use, you can only claim the work-use percentage. For example, if you use your laptop 70% for work, you claim 70% of its cost.

Common home office setup items and their deductibility:

Desk, chair, shelving — deductible at work-use percentage
Computer, monitor, keyboard, mouse — deductible at work-use percentage
Printer, scanner, external hard drive — deductible
Phone (if used for work) — deductible at work-use percentage
Office décor, artwork — generally not deductible unless directly work-related
Repairs and maintenance of existing home office items — deductible

Occupancy Expenses: Rent, Mortgage, and Rates

This is where many people get confused — and where the ATO draws a hard line. You can only claim occupancy expenses (rent, mortgage interest, council rates, land tax, home insurance) if your home is your principal place of business and you have a dedicated area set aside exclusively for business use.

For most employees working from home and many sole traders, this test is not met. The ATO's position is that if you also carry on your business from another location — such as visiting client sites, working from a co-working space, or if your home office is a spare room that doubles as a guest room — you generally cannot claim occupancy expenses. The risk of claiming occupancy costs incorrectly is also significant: it can trigger a capital gains tax (CGT) event when you sell your home, partially removing the main residence CGT exemption.

If your home genuinely is your principal place of business — for example, you're a bookkeeper or graphic designer who sees clients at home, has a dedicated locked office room, and does not maintain any other office — then you may be able to claim a proportion of rent or mortgage interest. Calculate the floor area of your dedicated workspace as a percentage of total home floor area and apply that to your annual occupancy cost. Get advice from a registered tax agent before claiming this for the first time.

CGT warning: Claiming occupancy expenses as a home office deduction can reduce your main residence CGT exemption when you sell. The ATO has issued specific guidance on this — see ATO.gov.au/homes. If you own your home, speak to a tax agent before claiming rent or mortgage interest.

Record-Keeping the ATO Actually Accepts

The ATO's compliance focus on work-from-home claims has sharpened since 2023. In 2026, the record-keeping requirements are non-negotiable — if you cannot substantiate your claim, it will be disallowed. The fixed rate method requires a log of actual hours worked from home for the entire income year. The actual cost method requires receipts, invoices, and a method to calculate the work-use percentage of shared expenses.

For the fixed rate method, acceptable records include timesheets, rosters, a diary or calendar (digital or paper), or time-tracking app exports. The ATO does not accept estimates or reconstructed records made after the fact. Start logging now — if you haven't kept records from 1 July 2025, reconstruct what you can from calendar entries, meeting records, and project logs, but the ATO may not accept these for the full year.

For equipment and furniture, keep every purchase receipt. If you buy a desk for $1,800 and claim it under the instant asset write-off, the ATO wants to see the tax invoice showing the amount, date, supplier name, and a description of the item. Store receipts digitally — a photo in a folder organised by financial year is fine. SAB Account AI lets you attach receipts directly to expense records so they're ready at EOFY without a last-minute search.

ATO red flag: Claiming 100% work use on a laptop or phone that you clearly also use personally is one of the most commonly flagged deductions. Be realistic — 70–80% work use is more defensible than 100%.

Record-keeping checklist:

Fixed rate: log actual hours every day you work from home
Actual cost: keep receipts, floor plan measurement, usage percentage calculation
Equipment: keep tax invoices showing item, cost, date, and supplier
Phone and internet: keep one monthly bill showing the total cost, then apply your work-use percentage
Do not reconstruct records at tax time — the ATO will not accept them

Home Office Deductions for Sole Traders vs Employees in 2026

The rules differ depending on your working arrangement. If you're a sole trader running a business from home, your deductions come through your business tax return (individual tax return with a business schedule) and you apply the small business depreciation rules. If you're an employee working from home — even full-time — you claim through the 'other work-related expenses' section of your personal tax return, and the depreciation thresholds are different.

Sole traders have a significant advantage: access to the $20,000 instant asset write-off threshold means you can write off most home office equipment in full in the year of purchase. An employee buying a $1,500 desk for their home office can write it off immediately only if it costs $300 or less — anything above $300 must be depreciated over its ATO-set effective life (typically 10–13 years for furniture).

For migrant workers and international students in Australia who are sole traders — a common situation for those running freelance or digital services businesses — these same rules apply. Your residency status for tax purposes (resident, non-resident, or temporary resident) affects your overall tax liability but does not change the deductibility rules for home office expenses. If you have an ABN and you're running a genuine business, you access the same deductions as any other Australian sole trader.

July 1, 2026 reminder: Payday Super starts on 1 July 2026. If you employ anyone — even casually, even one person — super must be paid on or before each payday from that date. This is a payroll compliance change, not a tax deduction issue, but it affects your cash flow. Factor super into your costs now. See our full guide on Payday Super 2026.

Practical Steps to Maximise Your Home Office Claim Before 30 June 2026

You have until 30 June 2026 to make purchases that qualify for deduction in the 2025–26 income year. If you need a new monitor, ergonomic chair, or external hard drive, buying before EOFY means you can claim it this year rather than waiting. Under the instant asset write-off, the asset must be installed and ready for use before 30 June — ordered but not delivered does not count.

If you're using the fixed rate method, your hours log should cover 1 July 2025 to 30 June 2026. If you've been inconsistent with logging, start now and be accurate for the remaining weeks. Do not inflate hours — the ATO cross-checks claimed hours against your income and can request your log as part of an audit. If you work 40 hours a week from home, log 40 hours. If it's 20 hours, log 20.

Finally, review your internet and phone plans. If you're still on a plan that doesn't reflect your actual work use, this is a good time to switch or at least document your usage split. The fixed rate method already bundles internet into the 70 cents rate, so if you use actual cost, you'll need last year's bills and a realistic work-use percentage. A tax agent can help you make the right call for your specific situation — and the cost of that advice is itself tax deductible.

Frequently asked questions

Can I claim my home internet as a tax deduction in 2026?

Yes, but only the work-use portion. If you use the fixed rate method (70 cents/hour), internet is already included in that rate and you cannot claim it separately. If you use the actual cost method, calculate what percentage of your internet use is for work and claim that percentage of your annual internet bill.

Can I claim the cost of a new desk and chair for my home office?

Yes. As a sole trader, items costing under $20,000 can be written off in full in the year of purchase under the instant asset write-off. As an employee, items over $300 must be depreciated over their effective life. In both cases, you can only claim the work-use percentage if the item is used for both work and personal purposes.

Does claiming home office expenses affect my capital gains tax when I sell my house?

Claiming occupancy expenses (rent, mortgage interest, council rates) can reduce your main residence CGT exemption when you sell. Claiming running costs (electricity, internet) and equipment depreciation under the fixed or actual rate methods does not affect your CGT exemption. Get tax advice before claiming occupancy costs.

What records does the ATO require for home office deductions in 2026?

For the fixed rate method, you need a log of actual hours worked from home covering the full income year. For the actual cost method, you need receipts, a floor area calculation, and usage percentages. For equipment, keep the original tax invoice. The ATO does not accept reconstructed or estimated records.

I'm an international student with an ABN running a freelance business. Can I claim home office deductions?

Yes. If you have an ABN and are running a genuine business, you access the same home office deduction rules as any other sole trader in Australia. Your visa type does not affect your eligibility to claim legitimate business expenses — but your tax residency status affects your overall tax rates, so check whether you're classified as a resident or non-resident for tax purposes.
