It is law — and it is the one change that hits this income year
The Treasury Laws Amendment (Tax Reform No. 1) Act 2026 (No. 49 of 2026) received Royal Assent on 26 June 2026. It is enacted law, not an announcement or a proposal — see enacted vs announced measures. Schedule 4 inserts a new section 25-130 into the Income Tax Assessment Act 1997, creating a standard deduction for work-related expenses.
Commencement is not application
Schedule 4 commenced on 1 July 2026, but item 17(1) applies the income tax amendments to assessments for the 2026-27 income year and later income years. Of the five schedules in the Act, this is the only one that reaches the income year now under way — the CGT, negative-gearing quarantining, Working Australians tax offset and SMSF borrowing measures all bite later. Nothing in Schedule 4 changes the 2025-26 return you may be lodging now.
| Part | What it changes | Commenced | First applies to |
|---|---|---|---|
| Part 1 (income tax) | New s 25-130; repeal of the $300 and $150 substantiation exceptions; depreciating-asset changes | 1 July 2026 | Assessments for the 2026-27 income year and later (item 17(1)) |
| Part 2 (FBT) | New s 24(1A) and substituted s 58X(2) of the FBTAA 1986 | 1 July 2026 | FBT years starting on or after 1 April 2027 (item 20) |
That gap is deliberate. Between 1 July 2026 and 31 March 2027 the income tax standard deduction operates while the existing FBT rules still apply — which matters for anyone reviewing salary packaging arrangements this year.
