New year, new tax traps. If you thought FY25 was going to be a smooth ride, think again. The ATO has rolled out some silent assassins in the form of new rates, revised thresholds, and compliance bombs — and they’re all coming for your refund, your deductions, or your super.
Here’s what’s changed, what it means, and how to play it smart.
1. ATO Debt Just Got More Expensive — and Not in a Fun “Offset It Later” Way
Starting 1 July 2025, you can no longer claim a tax deduction for interest on unpaid ATO debts. That includes your General Interest Charge (GIC).
Translation: That old habit of using the ATO as your unofficial lender? That’s now costing you 14–20% interest, after tax.
Our Advice: If you’ve got a tax bill lingering (and you’re not getting 20% ROI elsewhere), pay it off. Otherwise, consider refinancing that debt via a third-party lender while you can still deduct the interest.
2. 88 Cents Per Kilometre – But Only If You Can Prove It
The cents-per-km car claim rate just got bumped to 88¢/km for FY25. Sounds generous, right? But here’s the kicker — you still need a reliable method for calculating the kilometres, or it won’t stick in an audit.
Bonus Trap: Electric car drivers, you’re stuck at 42¢/km if you’re using actual expenses, which sounds low, but you may have options if your EV is under FBT exemption rules.
3. Super Caps Are Up — Which Means Bigger Tax Deductions (if you move now)
From 1 July 2024, your concessional super cap is now $30,000 (up from $27,500), and the non-concessional cap is $120,000. Catch-up strategies are back on the table.
Smart move: Use this year’s room + bring forward prior years = serious tax planning potential. Especially if you’re staring down a Div 293 tax bill.
4. Stage 3 Tax Cuts Are Here — But Don’t Celebrate Just Yet
Sure, marginal rates have dropped:
| Income Range | FY24 | FY25 |
| $45k–$120k | 32.5% | 30% |
| $120k–$180k | 37% | 30% |
| $180k+ | 45% | 45% |
But here’s what’s really happening:
👉 Less tax withheld each pay = smaller refund at year-end
👉 Clients will say, “Why is my refund lower?”
👉 You’ll say, “Because you already got it — just slower, and in pieces.”
5. Foreign Sellers of Aussie Property — You’re Now Withholding 15%, No Exceptions
From 1 January 2025, the foreign resident capital gains withholding:
- Rises from 12.5% → 15%
- Threshold? Gone. Now applies to all Australian property sales.
Got a foreign client selling real estate? They’ll need a clearance certificate or risk handing over a bigger chunk to the ATO at settlement.
6. HELP Indexation Refunds Are Real — But You Need to Ask
- The indexation for 2023 has been retrospectively reduced from 7.1% → 1.8%.
- If you overpaid, you might be due a refund. But guess what? It’s not automatic.
- Check your MyGov or reach out — we’ll chase it up for you (and make sure it doesn’t happen again).
7. The ATO Has Receipts — And They’re Coming
From 1 July 2025, the ATO is expanding its compliance programs:
- Personal income
- ABN matching
- Crypto gains
- International disclosures
You know that “mate” who sold shares, held crypto, and drove Uber on the side — but never told their tax agent? Yeah, the ATO knows now.
Final Thought From Your Tax Advisor
