Overview of the Changes
The Australian Government has legislated tax rate reductions for the 16% marginal rate bracket covering income from A$18,201 to A$45,000. Specifically:
- From 1 July 2026, the 16% rate drops to 15%.
- From 1 July 2027, that same bracket rate falls further to 14%. (ato.gov.au) These changes are part of the Treasury Laws Amendment (More Cost of Living Relief) Act 2025, passed into law in March 2025. (au.andersen.com)
Who benefits most
- Individuals earning in that bracket (A$18,201–A$45,000) see immediate rate relief.
- Middle income earners with multiple income streams may also benefit as these cuts reduce bracket creep and marginal rates at critical points.
- Pay-as-you-go (PAYG) systems may need adjustment by employers so that withholding aligns with new rates once effective dates arrive.
Planning strategies to maximise benefit
- Review withholding allowances or deductions — if you usually have PAYG adjusted through accumulation of deductions or investments, ensure you’re leveraging every allowable deduction before rates change.
- Defer income (if possible) — for small business owners or freelancers, carrying income into the 2026-27 year could result in lower overall marginal tax for income in the base bracket.
- Prepay deductible expenses in prior years where timing allows, e.g., subscriptions, repairs, or charitable donations, to use deductions while higher rate applies just before cut.
Examples for various scenarios
| Taxpayer | Current situation / Cut effect | Strategy suggestion |
|---|---|---|
| Sole trader earning A$40,000 | Moving from 16% to 15% in July 2026 -> tax cut ~A$100-150 | Delay invoicing until after 1 July so some income falls in new lower rate year |
| Part-time employee earning A$25,000 + small investments | New rate reduces PAYG withheld | Check investments with holding tax, itemise deductions in current year |
| Household with two incomes | Combined income partly triggers higher brackets | Shift deductions or assets to spouse in lower bracket where possible |
Caveats and transitional matters
- These rate reductions do not change other tax brackets — only the 16% bracket is affected.
- Remember the Medicare levy low income thresholds will also increase, helping low earners avoid or reduce the Medicare levy burden. (ashurst.com)
- Tax planning must always consider the whole fiscal year; expecting rates to change midway doesn’t permit pro-rating in many cases.
Start exploring what changes you can make now — review current withholding, organise expenses, consult with your accountant — so you receive maximum benefit once these tax cuts kick in.
