Australia Super Tax March 11: Greens Back Labor; Senate Set to Pass

Australia’s superannuation tax changes are set to clear the Senate after the Greens backed Labor’s bill. Earnings on super balances over $3m will face 30% tax up to $10m and 40% above $10m from July. The low-income super tax offset will rise to $810 from 1 July 2027. We explain who pays more, why the Greens Labor super deal matters, and how this could shift portfolios and property sentiment this budget season for Australian investors.

What passed and who pays

The superannuation tax changes introduce two higher tiers on earnings: 30% for balances between $3 million and $10 million, and 40% above $10 million, starting from July. This narrows concessions at the top while leaving lower balances unchanged. With Greens support, Senate passage is set, according to reports from ABC News source. We expect final detail in rules and ATO guidance ahead of commencement.

Australians with super balances over $3m will see higher taxes on earnings, especially those with self-managed funds holding illiquid assets. Most workers are untouched. For retirees, cash flow planning now matters more as earnings above thresholds face the new rates. The superannuation tax changes may shift strategies on when to retire, start a pension, or keep assets inside versus outside super.

To balance fairness, the low-income super tax offset (LISTO) rises to $810 from 1 July 2027. That helps workers whose super contributions are taxed above their income tax rate. The policy aims to lift retirement savings for lower-paid Australians, partly offsetting the stronger tilt against very large balances under the superannuation tax changes.

Budget and policy signals to watch

By narrowing concessions for very large accounts, the superannuation tax changes boost revenue across the forward estimates. That gives the budget more room to fund priorities without broad tax hikes. Markets will watch how Canberra allocates gains between cost-of-living relief, investment incentives, and debt reduction. Any mix affects consumption, corporate earnings, and listed sectors sensitive to fiscal settings.

The Greens’ support raises the chance of wider tax talks later in 2026, with the capital gains tax discount and negative gearing often cited as options. A shift here could change investor risk-reward between property, shares, and bonds. 9News reports the super passage could be paired with a push for further reforms this year source.

The Greens Labor super deal secures the Senate path by trading higher top-end super taxes for added support at the low-income end. It sets a precedent for targeted concessions rather than blanket changes. For investors, the political signal is clear: large tax shelters may face more scrutiny, while relief is targeted at workers and renters to ease cost pressures.

Portfolio implications for Australians

High-balance SMSFs may reassess asset mix and tax location. The superannuation tax changes make every dollar of earnings above $3m more expensive, especially for high-yield and capital-gain assets. We expect more attention on which assets sit inside pension versus accumulation, and whether some growth or tax-inefficient holdings shift outside super after advice.

For many investors, Australian shares with franked dividends still stack up inside super, even at higher rates, because credits reduce tax outside the fund. But at 30% and 40% tiers, the after-tax gap narrows. We may see tilts toward total-return strategies, global equities, and unlisted infrastructure funds to balance income, growth, and tax under the superannuation tax changes.

Talk of changes to the CGT discount or negative gearing could cool investor demand for leveraged property, at least short term. That may support listed real assets like REITs and infrastructure if yields look competitive. Portfolio reviews should stress test property-heavy allocations and consider liquidity, gearing costs, and cash buffers in case policy signals shift sentiment.

Practical steps before and after July

Start with a clear view of your total super balance across funds. Confirm contribution plans, pension status, and insurance. The superannuation tax changes bite only above $3m, but earlier moves can help long-term compounding. Keep records tight for asset valuations, especially unlisted holdings in SMSFs, so earnings are measured correctly against the new tiers.

Where couples have uneven balances, consider rebalancing strategies within current contribution rules after licensed advice. Review asset placement across super, personal, and trust accounts to target better after-tax outcomes. The goal is risk, liquidity, and tax working together, not a single-issue response to the superannuation tax changes.

Workers eligible for the low-income super tax offset should check payroll settings and future salary sacrifice levels. The lift to $810 from 1 July 2027 is a real benefit over time. Even small, steady contributions supported by LISTO can compound faster, helping to narrow retirement gaps while broader superannuation tax changes reshape incentives at the top.

Final Thoughts

The Greens’ backing means higher super taxes on very large balances are set to start from July, while the LISTO rises from 1 July 2027. For most Australians, day-to-day saving continues. For high-balance members, this is a tax-location and cash flow moment. Map which assets belong in pension, accumulation, or outside super, and model after-tax returns at 30% and 40% tiers. Stress test property exposure if negative gearing or the CGT discount come into play later this year. We suggest booking time with a licensed adviser before 30 June to confirm contributions, documentation, and valuation methods. Treat the superannuation tax changes as a prompt to refresh goals, risk, and liquidity, not just to trim tax.
