Working from home tax deductions let you claim a slice of your household running costs against your income, but navigating the Australian Taxation Office (ATO) rules can feel complex. Staring at a pile of bills and wondering what you can actually claim is a common frustration for employees and sole traders alike, and getting it wrong carries compliance risks.

This guide provides practical, compliance-first details to help you claim correctly.

Key Takeaways on Tax Deductions Working From Home

• Two Deduction Methods: You can use the ATO’s revised 67c fixed-rate method or the more detailed actual cost method. The old shortcut method has ended.
• Records Are Non-Negotiable: The ATO requires strict substantiation. You must keep a record of all hours worked from home for the entire financial year to use the fixed-rate method or detailed receipts and a 4-week diary for the actual cost method.
• Running vs. Occupancy Expenses: You can generally claim running costs like electricity, internet, and stationery. Claiming occupancy expenses (rent, mortgage interest) is complex and can trigger Capital Gains Tax (CGT) when you sell your home.
• Equipment Rules: You can claim the full cost of equipment under $300 immediately. Assets over $300 must be depreciated over their effective life.
• Check Your Entitlement: You must incur additional running costs as a direct result of working from home to be eligible to claim.

What Counts as Working From Home for Tax Purposes?

Before calculating deductions, it’s crucial to understand what the ATO considers a legitimate work-from-home arrangement. To claim tax deductions working from home, you must be working from home to fulfil your employment duties, not just occasionally checking emails on the couch.

Crucially, you must incur additional, deductible running expenses as a direct result of your work. If you don’t pay for the bills at your home, you can’t claim a deduction.

The ATO’s rules are designed to allow you to claim the work-related portion of these additional costs. For detailed eligibility criteria, refer to the official ATO working from home deductions guide.

ATO Deduction Methods Explained

For the current financial year, the ATO provides two methods to calculate your claim: the revised fixed-rate method and the actual cost method. The “shortcut method” (80 cents per hour) is no longer available.

Choosing the right one impacts how much you can claim and the records you must keep. Neither method is universally “better”; the optimal choice depends on your expenses and willingness to handle the required administration.

The 67c Fixed-Rate Method

The revised fixed-rate method is designed for simplicity. You can claim a flat rate of 67 cents for every hour you work from home. This rate is an all-inclusive figure covering your main additional running costs.

The 67 cents per hour claim covers:

• Energy (electricity and gas) for heating, cooling, and lighting.
• Internet expenses.
• Mobile and/or home phone usage.
• Stationery and computer consumables (e.g., printer ink).

Critical Record-Keeping: To use this method, you must keep a record of the total number of hours you worked from home for the entire financial year. The ATO does not accept estimates. You can still make separate claims for the depreciation of equipment like computers and office furniture. For full details, see the ATO’s guidance on the fixed-rate method.

The Actual Cost Method

The actual cost method requires more detailed work but can result in a larger deduction if you have significant home office expenses. With this approach, you calculate the specific work-related portion of every single eligible expense.

This means you must keep:

• Receipts or bills for every expense you claim.
• A record of your hours worked from home.
• A diary or similar record for a representative four-week period to establish a pattern of use for shared costs like electricity, internet, and phone usage.

While it is a greater administrative commitment, the extra effort often pays off for those with a dedicated, high-use home office. Learn more at the ATO’s page on the actual cost method.

Eligible vs Non-Eligible Home Office Deductions

This table outlines what you generally can and can’t claim as home office expenses under the actual cost method.

Eligible Expenses (Running Costs)	Non-Eligible Expenses (Private/Capital Costs)
Electricity for heating, cooling, and lighting your workspace	Rent or mortgage interest (generally not for employees)
Work-related portion of internet bills	Council and water rates
Work-related portion of mobile and/or home phone bills	Land taxes or home insurance
Stationery and computer consumables (ink, paper)	Coffee, tea, milk, and other general household items
Cleaning costs for a dedicated work area	Items your employer provides or reimburses
Decline in value (depreciation) of home office equipment & furniture	Expenses related to your children’s education

How to Calculate Your WFH Deduction

Calculating your tax deductions working from home correctly is a four-step process.

1. Choose Your Method: First, decide whether the 67c fixed-rate method or the actual cost method is better for you. Consider your total expenses and the records you have kept. If unsure, calculate your claim using both methods and choose the one that yields a higher deduction.
2. Gather Your Records: Collect all necessary documents. For the fixed-rate method, you need your full-year log of hours. For the actual cost method, you need all receipts, bills, your home office logbook, and your work-use percentage calculations.
3. Calculate the Deduction:
   • Fixed-Rate: Multiply your total hours worked from home by $0.67. Add any separate claims for equipment depreciation.
   • Actual Cost: For each expense, calculate the work-related portion (e.g., $90 monthly internet bill x 40% work use = $36 claim per month). Sum up all individual claims for the year.
4. Lodge Your Tax Return: Enter the final calculated amount at the “Working from home expenses” section in your tax return. Ensure you keep all your records for at least five years in case the ATO requests substantiation.

Worked Example: Fixed-Rate vs Actual Cost Method

Let’s compare the methods using a practical scenario. Priya is an employee who worked 1,800 hours from home this financial year.

Priya’s Expenses:

• Total annual electricity bill: $2,400
• Total annual internet bill: $1,080
• New office desk and chair: $800 (depreciated over 10 years = $80/year)
• New laptop: $1,500 (depreciated over 2 years = $750/year)
• Her home office logbook shows 40% work use for internet and 10% work use for electricity (based on floor area).

Calculation 1: 67c Fixed-Rate Method

Under this method, the electricity and internet costs are bundled into the hourly rate.

• Running Costs: 1,800 hours × $0.67/hour = $1,206
• Depreciation (separate claim): $80 (desk/chair) + $750 (laptop) = $830
• Total Fixed-Rate Claim: $1,206 + $830 = $2,036

Calculation 2: Actual Cost Method

Here, Priya calculates the work portion of each specific cost.

• Electricity: $2,400 × 10% work use = $240
• Internet: $1,080 × 40% work use = $432
• Depreciation: $80 (desk/chair) + $750 (laptop) = $830
• Total Actual Cost Claim: $240 + $432 + $830 = $1,502

Result: In this scenario, the 67c fixed-rate method provides a significantly higher deduction ($2,036 vs $1,502). This example shows why it’s crucial to assess both methods, as high equipment costs can make the fixed-rate method more attractive.

Record-Keeping Requirements (ATO)

A tax deduction is only valid if you have the records to prove it. The ATO’s substantiation rules are strict, and estimating expenses is not permitted. Your records are your evidence. Without them, your claim can be denied during an audit.

To stay compliant, you must meticulously document your hours and expenses throughout the income year.

• Log Your Hours: You must keep a year-long record of hours worked from home (e.g., timesheets, diary, or spreadsheet). Estimates are no longer accepted by the ATO.
• Keep Receipts: Retain all invoices and receipts for expenses claimed, including utility bills, phone plans, and proof of purchase for equipment.
• Document Depreciation: For assets over $300, you must have the purchase receipt and a record of how you calculated their depreciation. Find out more about ATO equipment depreciation.

What You Need Before Lodging

Run through this checklist to ensure your claim is ATO-compliant.

Copy-Paste Checklist for ATO Compliance:

•  I have a complete log of all hours worked from home for the financial year.
•  I have kept receipts and invoices for every individual expense I am claiming under the actual cost method.
•  For shared costs (internet/phone), I have a four-week representative diary or another reasonable basis for my work-use percentage calculation.
•  For depreciating assets (over $300), I have the purchase receipt and my depreciation schedule.
•  I have a clear calculation method for my business-use percentage of shared expenses.
•  I have reviewed my claims to ensure no private expenses (like coffee or rent for employees) are included.

Special Rules You Need to Know

Shared Expenses (Internet, Phone, Electricity)

When claiming shared household utilities, you can only deduct the additional expense incurred from working at home. You must apportion the cost between private and work use on a reasonable basis. A common method is keeping a four-week home office logbook to establish a pattern of work-related use, which can then be applied across the year.

Equipment Under vs Over $300

The $300 threshold is a key rule for home office equipment.

• Items costing $300 or less: You can claim an immediate deduction for the full work-related portion in the year you buy them.
• Items costing more than $300: You cannot claim the full cost upfront. Instead, you must claim the decline in value (depreciation) over the asset’s effective life. Learn how to claim a laptop on your tax return.

Occupancy Expenses and CGT Impact

This is a critical area. Occupancy expenses are costs related to owning or renting your property, such as mortgage interest, rent, council rates, and insurance.

While sole traders running a business from home may be able to claim these, employees generally cannot. If an employee claims occupancy expenses, they are telling the ATO that a portion of their home was used to produce income. This may cause that part of the home to lose its main residence exemption, leading to a Capital Gains Tax (CGT) liability upon sale. For most employees, the risk far outweighs the benefit.

Sole Traders vs Employees

While both can claim WFH deductions, there are differences.

• Employees can claim running expenses but should avoid claiming occupancy expenses to preserve their CGT main residence exemption.
• Sole traders who run their business from a dedicated home office may be entitled to claim both running and occupancy expenses. However, claiming occupancy costs will still have CGT implications.

Common Mistakes & Quick Fixes

The ATO is closely monitoring tax deductions working from home, so avoiding common errors is crucial. Discover more about the ATO’s latest focus areas on WFH compliance to understand the audit risks.

• Mistake: Estimating the total hours worked from home.
• Quick Fix: Keep a continuous, year-long record of your actual hours. Use a diary, timesheet, or spreadsheet. The ATO’s position is clear: no logbook, no claim under the fixed-rate method.
• Mistake: Claiming 100% of phone or internet bills.
• Quick Fix: Apportion the expense. Keep a four-week representative diary to determine a reasonable work-use percentage and apply it to your bills.
• Mistake (for employees): Claiming rent or mortgage interest.
• Quick Fix: Do not claim occupancy expenses unless you have received professional tax advice. The potential CGT consequences of claiming these costs are significant and usually outweigh the small deduction.
• Mistake: Claiming general household items like coffee, tea, and milk.
• Quick Fix: These are private expenses and are not deductible. Stick to claiming costs directly related to your income-earning activities.

Frequently Asked Questions

What tax deductions can I claim working from home? You can claim additional running expenses like electricity, internet, phone usage, stationery, and the depreciation of office equipment. You can use either the 67c fixed-rate method or the actual cost method to calculate your claim.

Which working-from-home method should I use? Use the 67c fixed-rate method for simplicity if you have good hour-logs. Use the actual cost method if you have high running costs and detailed receipts, as it may result in a larger deduction. It’s wise to calculate both and choose the higher claim.

How does the 67c fixed-rate method work? You claim 67 cents for every hour you worked from home. This rate covers electricity, gas, internet, phone, and stationery. You must keep a record of all hours worked and can still claim depreciation on equipment over $300 separately.

Can I claim rent or mortgage interest? Generally, employees should not claim rent or mortgage interest. Doing so can affect your home’s main residence exemption from Capital Gains Tax (CGT). Sole traders may be able to claim a portion, but CGT will likely apply when the property is sold.

Do I need records or a logbook? Yes. Records are mandatory. For the fixed-rate method, you need a log of all hours worked. For the actual cost method, you need receipts for all expenses and a home office logbook (e.g., a 4-week diary) to prove your work-use percentage for shared costs.

What home office expenses are not deductible? You cannot claim private expenses like coffee, tea, or snacks. For employees, occupancy expenses like rent, mortgage interest, and rates are also generally not deductible due to CGT implications.

What happens if I claim occupancy expenses? Claiming occupancy expenses tells the ATO that part of your home is used for income-producing purposes. This means that portion of your home may no longer be eligible for the CGT main residence exemption, and you will likely have to pay CGT when you sell.

Does claiming WFH affect CGT? Claiming running expenses (electricity, internet) does not affect CGT. Claiming occupancy expenses (rent, mortgage interest) does affect CGT and can lead to a significant tax bill when you sell your home.
