This hub tracks tax and superannuation changes taking effect in the 2026-27 Australian financial year. Primary source for every figure here is the Australian Taxation Office (ATO) and federal Budget papers, cited at the bottom. Figures are updated when the ATO publishes indexation numbers.

Stage 3+ second phase income tax cut

From 1 July 2026, the second marginal tax bracket rate drops from 16 percent to 15 percent, applied to taxable income between $18,201 and $45,000. This is the legislated second phase of the 2024 Stage 3+ income tax cut.

  • Every taxpayer earning above $18,200 is better off by up to $268 per year compared to 2025-26.
  • The third phase, which cuts the same bracket to 14 percent, is legislated for 1 July 2027.
  • The Medicare levy (2 percent) and Medicare levy surcharge rules are unchanged.

Superannuation Guarantee rate

The Superannuation Guarantee (SG) rate remains at 12 percent. The SG reached 12 percent on 1 July 2025 and that is now the permanent rate. No further increase is legislated.

Same-day super (Payday Super)

From 1 July 2026, Australian employers must pay SG contributions on the same day they pay wages, rather than quarterly. This closes the gap that previously let employers hold super for up to three months, reducing the risk of unpaid or lost super.

HECS / HELP repayment threshold

The 2025-26 HECS/HELP minimum repayment threshold is $67,000. The 2026-27 threshold will be indexed by the Consumer Price Index from the March 2026 quarter, with the ATO publishing the new figure in May or June 2026. Check the ATO website for the final 2026-27 figure once it is released.

What to check before 30 June

  • Concessional super contributions cap ($30,000) and non-concessional cap ($120,000) if you have capacity.
  • Work-related deductions with receipts, supported by an ATO logbook where required.
  • Capital gains events timing if you are considering selling investment assets.
  • Rental property expenses and the depreciation schedule.

Payment dates and deadlines

The 2025-26 individual tax return is due 31 October 2026 if lodging directly. Registered tax agents have extended deadlines under the ATO lodgment program. The 2026-27 financial year runs 1 July 2026 to 30 June 2027.
