The Australian Taxation Office (ATO) has ramped up audit activity this financial year with nearly $1 billion in extra compliance funding — and it’s not just talk. Backed by cutting-edge data-matching tech pulling info from over 350 sources, the ATO’s reach has never been wider.

At Supertax, we’re seeing firsthand how these changes are impacting everyday taxpayers. The good news? If you’re compliant, you’ll benefit with faster returns and bigger legitimate refunds. The bad news? If you’re not — the ATO will likely know.

Here’s what every taxpayer needs to know about the ATO’s top 2025 audit targets, how to stay safe, and when to seek professional help.

🚨 ATO’s 2025 Audit Priorities: Who’s in the Firing Line?

1. Rental Property Claims – 90% Error Rate

Risk Level: High

ATO audits found errors in 90% of rental property claims reviewed. Key issues include:

• Incorrect loan interest deductions (e.g., including your home loan)
• Confusing capital improvements with repairs
• Claiming expenses on holiday homes or Airbnbs that aren’t genuinely available for rent

🔍 ATO Focus: Data from 17+ major lenders, Airbnb & short-stay platforms, and property managers.

✅ Supertax Tip: Keep:

• Loan statements showing personal vs investment use
• Advertising records to prove genuine rental availability
• Receipts for repairs vs capital works (new kitchens, extensions = capital)

2. Work-From-Home Deductions – The $8.7B Gap

Risk Level: High

Work-from-home claims are under the microscope in 2025.

• New fixed rate: 70 cents/hour (up from 67c), but stricter rules apply
• You must track every hour you WFH for the entire year — no more 4-week diaries
• You can’t separately claim phone/internet if using the fixed rate

✅ Supertax Tip: Maintain:

• Daily time logs or rosters
• Employment contracts confirming hybrid/WFH
• Utility bills and equipment receipts (for actual expense method)

3. Cryptocurrency Transactions

Risk Level: Medium-High

Think the ATO doesn’t know about your crypto wallet? Think again. Their crypto data-matching program dates back to 2014.

🚩 Common issues:

• Not declaring crypto-to-crypto trades (they’re taxable disposals)
• Treating mining/staking rewards as capital gains (they’re income)
• Poor record-keeping

✅ Supertax Tip: Keep:

• Full transaction histories
• Exchange records showing AUD values
• Wallet addresses and purposes for transfers

Mining/staking income and expense records (e.g., electricity)

4. Gig Economy Income – Side Hustle Scrutiny

Risk Level: Medium

Platforms like Uber, Airtasker, and Airbnb now report directly to the ATO.

🚨 Key rule: If you carry passengers for a fare (e.g., Uber), you MUST be registered for GST — even if you earn under $75,000.

✅ Supertax Tip: Declare:

All income from platforms

• Vehicle costs, internet/phone bills, platform fees
• Use a separate bank account to track business activity

5. Small Business – Business/Personal Expense Mixing

Risk Level: Medium

Small business owners often slip up by:

• Claiming personal costs as business expenses
• Using rounded numbers without evidence
• Not separating finances

✅ Supertax Tip:

• Use separate accounts and cards
• Keep original invoices and bank statements
• Log transactions regularly — don’t rely on memory

🛡️ How to Audit-Proof Your 2025 Tax Return

• Report all income (including crypto, Airbnb, rideshare, side hustles)
• Keep detailed records: no round numbers, no estimates
• For rental claims: show property was genuinely available
• For WFH: track actual hours and understand your method
• Separate business and personal spending
• Keep tax records for at least five years

💼 When Should You Seek Professional Help?

• Own a rental property
