Work From Home Tax Claims 2025: ATO Audit Risk Guide

Working from home has become the new normal for millions of Australians, but here’s the thing: the ATO’s crackdown on home office deductions means your claims could trigger an audit faster than you can say “tax refund.” The simplified COVID-19 claiming methods are gone, and the ATO now requires detailed records for every dollar claimed under either the actual cost method or fixed rate method.

We’ve helped thousands of Australians through ATO reviews over our 50+ years in the tax game, and we’re seeing more work from home audits than ever before. The key is understanding what triggers reviews and keeping bulletproof records that would make a forensic accountant weep with joy.

Quick Summary: What Puts You at Risk?

The ATO is watching for these red flags like a hawk eyeing a field mouse:

Claims without proper substantiation or record keeping
Using outdated shortcut methods from the COVID-19 period
Claiming expenses without proper work-related apportionment
Round number claims that appear estimated rather than calculated
Missing work diaries for the fixed rate method
Inadequate records for the actual cost method

Key rules for 2024-25:

Two methods available: fixed rate method (70 cents per hour) or actual cost method with detailed substantiation
Records required showing additional running expenses incurred as a direct result of working from home
Work diary documenting actual home working hours for fixed rate method
Clear separation between work and private use portions

Why the ATO is Cracking Down on Working From Home

Work from home claims must now show you’re actually working from home to fulfil employment duties, not just carrying out minimal tasks like occasionally checking emails. Think of it this way: if you’re just answering the odd phone call from your couch while watching Netflix, that doesn’t count as working from home.

“We’re seeing review letters for work from home claims that would have sailed through five years ago,” says ITP tax advisor Bruce Gannon. “The ATO now cross-checks your claims against employment records, bank data, and spending patterns like a digital detective.”

The ATO employs sophisticated data-matching technology to compare information from different sources and identify potential compliance issues. If your claims don’t match your actual work patterns, you’ll definitely hear about it.

Red Flags That Trigger Reviews

Certain claiming patterns are like sending up flares to the ATO. Here’s what gets their attention:

Maximum amount claims happen when people always claim the highest allowable amounts regardless of actual expenses. It looks suspicious because real life isn’t that neat and tidy.

Round number claims are another giveaway. Neat figures like exactly $1,000 or $500 suggest estimates rather than actual calculations.

Employment inconsistencies raise immediate red flags when you’re claiming significant home office expenses while your employer reports you as office-based. The numbers just don’t add up.

Missing records are the biggest problem of all. Claims without supporting work diaries, receipts, or calculation worksheets face automatic disallowance under substantiation rules.

“The biggest audit trigger is inadequate record keeping,” notes Bruce. “Clients who can’t produce detailed records face penalties on top of claim disallowance.”

What You Can Actually Claim (And How)

For 2024-25, you must use either the fixed rate method or actual cost method for all work from home claims. The simplified COVID-19 methods are permanently discontinued.

Fixed Rate Method (70 cents per hour)

The fixed rate for 2024-25 is 70 cents per hour worked from home. This rate covers these expenses:

Electricity and gas for heating, cooling and lighting
Internet and phone expenses
Stationery and computer consumables

What you need for this method:

A record of actual hours worked from home for the entire income year (estimates are not accepted)
Evidence you paid for the expenses covered by the rate
You can claim separate deductions for decline in value of assets like computers and office furniture

The beauty of this method is that you don’t need a dedicated home office space. Working from your kitchen table? No worries. Just make sure you’re actually working, not just scrolling through social media.

Actual Cost Method

Using the actual cost method, you calculate the actual additional expenses you incur when working from home. This method requires more detailed records but can be more beneficial if your actual costs are higher than the fixed rate.

Running expenses you can claim (work portion only):

Electricity for lighting, heating, cooling your work area
Gas for heating your workspace
Internet and phone costs for work purposes
Stationery and office supplies used for work

Equipment and furniture (work-related portion):

Computers, laptops, tablets used for work
Office furniture used primarily for work
Work-required software subscriptions
Printers and office equipment for work

What you cannot claim:

Occupancy expenses like rent, mortgage interest, house insurance, council rates unless you have a dedicated area set aside as a ‘place of business’
Entire utility bills without proper apportionment
Equipment used mainly for personal purposes

Where you incur running expenses for both private and work purposes, you need to apportion your deduction on a fair and reasonable basis. If you work from home 20% of your total work hours and use your study 50% for work purposes, you can claim 10% of relevant expenses (20% × 50% = 10%).

Record Keeping That Actually Protects You

Here’s where most people go wrong: they think they can wing it with record keeping. You can’t. The ATO requires you to keep your written evidence for 5 years from the date you lodge your tax return. Here’s what you absolutely need:

Work Diary Requirements (Fixed Rate Method):

Start a work diary today and record these details every time you work from home:

Daily record of actual hours worked from home for the entire income year
Start and finish times each time you work from home
Nature of work performed at home
Regular office attendance patterns

Expense Documentation:

Keep these records like your financial life depends on it (because it does):

Original receipts for all equipment purchases
Utility bills for apportionment calculations
Internet and phone bills with work usage identified
Evidence of what your employer provides

Calculation Worksheets:

Show your working like you’re back in maths class:

Detailed work-related percentage calculations
Apportionment methods for shared expenses
Annual summaries by expense category

“Clients who sail through ATO reviews maintain comprehensive records from day one,” explains ITP senior advisor Jennifer Harris. “It’s easier to keep good records than reconstruct them during an audit.”

Safe Claiming Strategies

Based on our experience with ATO reviews, these approaches minimise audit risk while maximising your legitimate claims:

Conservative calculations work in your favour. When uncertain about work percentages, use defensible conservative estimates rather than aggressive maximums. It’s better to claim $800 confidently than $1,200 nervously.

Focus on obvious work expenses because computer equipment and work-specific software are easier to defend than general household costs. The ATO rarely questions a genuine work laptop purchase.

Professional equipment priority helps because claims for clearly work-related items rarely face challenge compared to utility apportionments. A printer used 80% for work is easier to defend than 80% of your electricity bill.

Regular documentation updates save you headaches later. Keep records current as work arrangements change throughout the year. Don’t rely on your memory come tax time.

Professional Compliance Checklist

Before you lodge your return, tick off these essentials:

Work diary with daily hours and locations documented
Original receipts for all claimed equipment and expenses
Accurate work-related percentages calculated and documented
Employer policies on equipment provision clearly understood
Work and private use properly separated in all calculations
Digital records stored with secure backup systems
Annual review of claiming calculations when arrangements change
Professional advice for complex situations or significant claims

You can use the ATO’s home office expenses calculator to help calculate your deduction under either method.

When Professional Help Becomes Essential

Work from home compliance has become complex enough to warrant professional guidance in many situations. Don’t try to be a hero if you’re out of your depth.

You definitely need help if you have multiple work locations with varying schedules, have received any ATO correspondence about your claims, make significant work from home claims worth professional review, or find record keeping requirements overwhelming.

Our tax return specialists understand the ATO’s current focus and can structure your claims to minimise review risk while maximising legitimate deductions. Our bookkeeping services handle complex employment and contractor arrangements that affect home office claims.

The Bottom Line for 2025

The ATO’s work from home compliance focus isn’t temporary. It’s the new normal, like remote meetings and awkward video call backgrounds. Sophisticated data matching and systematic reviews mean casual record keeping and estimated claims will cost you more than a decent coffee machine.

Your protection is meticulous records, conservative claims, and professional guidance when needed. The goal isn’t maximising your refund at all costs. It’s ensuring every dollar claimed can be defended confidently if the ATO comes knocking.

Success in this environment means treating work from home claims with the same seriousness as any significant tax deduction. Done right, you’ll sleep well knowing your claims are bulletproof. Done wrong, and you might find yourself explaining your Netflix viewing habits to an ATO auditor.

Your Work From Home Claims Questions Answered

Can the ATO audit my work from home claims?

Yes, the ATO conducts audits where they consider a more in-depth examination is required, using data matching programs that cross-reference tax claims with employment records and spending patterns. They’re particularly focused on work from home claims right now.

What triggers an ATO review of home office deductions?

Common triggers include reporting discrepancies, high-risk industries or transactions, and non-compliance with record-keeping requirements. Round number estimates, inconsistent work patterns, and inadequate records also raise red flags.

How much can I claim without detailed records?

If an expense is subject to substantiation, it must be supported by written evidence. If not, your claim is not deductible. All work from home claims now require proper substantiation regardless of amount.

What happens if I can’t prove my claims?

If you don’t have evidence to support claims for a deduction during a review, your claims can be disallowed. You’ll pay back any refund received plus interest and potential penalty amounts.

Can I claim my entire internet bill as work expense?

No, where you incur running expenses for both private and work purposes, you need to apportion your deduction on a fair and reasonable basis. You can only claim the work-related portion.

What if I work from home some days and office others?

You need to keep a record of actual hours worked from home for the entire income year and only claim expenses for genuine work from home days, properly apportioned for actual work use.

How long should I keep work from home records?

You must keep your written evidence for 5 years from the date you lodge your tax return. The ATO can review claims within this period and you need comprehensive records to defend questioned claims.

Do I need records if my employer provides equipment?

Yes, you need records to prove additional work-related expenses claimed. You cannot claim employer-provided items and must prove what you personally purchased for work use.
