What the Working Australians tax offset is
Schedule 3 of the Treasury Laws Amendment (Tax Reform No. 1) Act 2026 — Act No. 49 of 2026, which received Royal Assent on 26 June 2026 — inserted a new Subdivision 61-E into the Income Tax Assessment Act 1997. Subdivision 61-E creates the Working Australians tax offset: an amount applied against the income tax you would otherwise pay for the year.
A tax offset is not a deduction and not a payment. A deduction reduces your taxable income, so it is worth your marginal rate on the amount claimed. An offset is subtracted from the tax itself. This one is subtracted from your basic income tax liability — the tax worked out on your taxable income at the applicable rates, before offsets are applied.
It is law — but not yet claimable
Schedule 3 commenced on 1 July 2026. That is when the provisions entered the statute book. It is not the year the offset becomes available. The application provision (Schedule 3, item 4) is the one that governs when anyone can claim it, and it points to 2027-28.
