Why $150k is the New $100k: How to Stop the ATO Taking the Difference
Hitting a six-figure salary used to be the ultimate Australian financial milestone. It meant you had made it. Today, anyone trying to pay a mortgage and buy groceries in the Sutherland Shire knows that the math has fundamentally changed. Earning $150,000 in 2026 feels a lot like earning $100,000 a decade ago, and a massive part of that frustration comes down to how the Australian Taxation Office treats your income.
Even with the recent Stage 3 tax cuts stretching the 30 percent tax bracket up to $135,000, earning a $150,000 salary pushes you firmly into the next tier. Every single dollar you earn above $135,000 is taxed at 37 percent. When you factor in the mandatory 2 percent Medicare Levy, you are losing 39 cents of every top-tier dollar straight to the government. You feel like you are earning more, but your actual take-home pay is shrinking in real terms due to inflation and bracket creep.
The secret to combating this is not just earning less, but structuring your finances so the ATO legally sees a smaller taxable income.
The most powerful and underutilised tool for high-income earners is the carry-forward concessional superannuation rule. Many professionals know the standard pre-tax super contribution cap is currently $30,000 per year. What they forget is that if their total super balance is under $500,000, the ATO allows them to access any unused cap amounts from the previous five financial years. If you had a few years where your employer only paid $10,000 into your fund, you have tens of thousands of dollars in unused caps sitting there. You can make a massive lump sum contribution right now to completely drag your taxable income back down below that brutal $135,000 threshold, saving thousands in immediate tax while boosting your retirement.
Another major blind spot for high-income earners is the Medicare Levy Surcharge. Earning $150,000 puts a massive target on your back if you do not hold appropriate private hospital cover. For singles earning over the base threshold, the ATO will slap you with an extra 1 to 1.5 percent tax penalty. Paying for a basic, compliant health policy is often mathematically cheaper than paying the surcharge penalty, yet thousands of Australians simply hand that extra cash over to the ATO every single year out of sheer laziness.
We also constantly see couples falling into the income distribution trap. If you earn $150,000 and your partner works part-time earning $40,000, any interest from high-yield savings accounts or dividend income held in joint names is heavily penalised. Shifting cash investments or shares entirely into the name of the lower-earning spouse is a fundamental structural fix. Their tax rate on that investment income might be as low as 16 percent, while you would be paying 39 percent on the exact same money.
The 2026 End of Financial Year is approaching fast, and the window to set up these structural changes closes on June 30. If you feel like you are paying too much tax, or if you are still sitting on an unlodged 2025 tax return, it is time to get it sorted.
