The CGT discount changes from 1 July 2027: what the law actually says
Schedule 1 of the Treasury Laws Amendment (Tax Reform No. 1) Act 2026 is law and commenced on 1 July 2026, but its substantive changes apply only to CGT events happening on or after 1 July 2027. This resource sets out exactly who keeps a discount, who falls to 0%, and how the replacement cost-base indexation is confined.

The standard deduction for work expenses from 2026-27: a floor, not a bonus
New section 25-130 of the ITAA 1997 applies to assessments for 2026-27 — the only measure in the Treasury Laws Amendment (Tax Reform No. 1) Act 2026 that applies to income tax assessments for the income year now under way. It gives eligible individuals a standard deduction of up to $1,000, reduced dollar for dollar by their listed work-related deductions, and it repeals the $300 and $150 substantiation exceptions.

The Working Australians tax offset: law now, claimable from 2027-28
Schedule 3 of the Treasury Laws Amendment (Tax Reform No. 1) Act 2026 inserted a new Working Australians tax offset into the income tax law. It commenced on 1 July 2026 but first applies to assessments for the 2027-28 income year — and $250 is its ceiling, not a universal entitlement.

The six-year rule: treating a former home as your main residence for CGT
How the absence choice in section 118-145 lets you keep treating a former home as your CGT-exempt main residence — the six-year limit while it earns rent, how the clock resets, the partial exemption past the limit, and the foreign resident restriction.

Reading notes
What each resource answers
- Individual income tax rates for 2026-27: what changed on 1 July
Answers “what rate applies to my income this year?” — the first read before estimating any 2026-27 position. It sits first on this shelf because nearly every other resource in the collection assumes you already know which bracket your income lands in, and the marginal-rate arithmetic here is what turns any deduction or offset into an actual dollar figure. Return to it whenever a pay rise, bonus or second job moves your taxable income near a threshold.
- The standard deduction for work expenses from 2026-27: a floor, not a bonus
Read before deciding whether to keep collecting receipts: it explains when itemising still beats the new floor. It earns its place because the measure is the most widely misread of the 2026 changes — the design is a floor beneath your work-related claims, not an amount added on top of them. Employees with modest expenses should read it once now to decide whether receipts are still worth keeping, and again before the 2026-27 return is lodged.
- Cents per kilometre or logbook? How to claim work-related car expenses
For anyone driving for work without a logbook: what each method demands, while there is still time to keep one. It belongs in a personal-tax collection rather than a business one because the choice is made by employees as much as by sole traders — and it can only be made properly with twelve weeks of records behind it. If your work driving is growing, read it before the kilometres accumulate: the method decision is far easier made in advance than reconstructed at tax time.
- The six-year rule: treating a former home as your main residence for CGT
Read the moment you move out of a home you might later rent — the choice is easiest made early. In practice this rule tends to arrive too late: by the time the question is asked, the property has been rented for years and the evidence of when it stopped being the main residence was never kept. If the home is already earning rent, read it alongside the CGT records checklist in the Property Investors collection, because the two problems are usually solved together.
- Division 293 tax explained: the extra 15% on super contributions for higher earners
For the year income first passes the trigger point: it explains the assessment that otherwise arrives as a surprise. It is shelved here rather than under superannuation because the assessment lands through the personal tax system, and the income definition it uses is broader than taxable income alone — which is how bonuses, capital gains and fringe benefits can tip a single year over the line. Worth re-reading in any year with a one-off income spike, even if salary alone sits below the trigger.
- The CGT discount changes from 1 July 2027: what the law actually says
Answers “does the timing of my sale matter?” — worth reading before settling on any disposal date. This is the resource in the collection where headlines and the enacted text diverge most sharply, and the transition date does the real work: the treatment turns on when the CGT event happens, not on when the asset was bought. Anyone holding an appreciating asset outside super should understand that timeline well before 1 July 2027 arrives.
- The Working Australians tax offset: law now, claimable from 2027-28
An expectation-setter: what the new offset is worth, and why it is absent from this year’s return. Its job on this shelf is largely preventative — heading off the assumption that a legislated offset must be claimable immediately, when the first return it can appear in is still a year away. Read it if you are budgeting around announced tax relief, and note that the figure quoted in coverage is a ceiling tied to labour income, not a universal payment.
About this collection
Personal tax, documented layer by layer
Personal tax in Australia is really several systems stacked on top of each other: marginal rates and thresholds that shift with each Budget, deduction rules with their own substantiation demands, capital gains tax with its exemptions and elections, and surcharge layers such as Division 293 that only appear once income passes a trigger point. This collection documents each layer as a standalone reference — what the rule is, which financial year it applies to, and the exact ATO or Treasury source that says so — rather than flattening everything into generic tax tips.
The audience is individuals and families rather than businesses. If you earn a salary, claim work-related expenses, own or once owned a home, contribute to super, or want to know what the legislated changes ahead will do to your return, these references are written for you. Business owners looking for GST, BAS or employer obligations should start in the Business, BAS & Payroll collection instead.
The questions answered here are the ones that actually arrive in a tax practice. Individual income tax rates for 2026-27 sets out what changed on 1 July and what a given taxable income now attracts. The standard deduction for work expenses explains why the new floor is not a bonus on top of your claims. Cents per kilometre or logbook? works through the choice between the two car-expense methods, and the six-year rule covers treating a former home as your main residence for CGT after you move out and rent it.
A second thread tracks legislated change before it bites. The CGT discount changes from 1 July 2027 and the Working Australians tax offset both explain what the Acts actually say — and, just as importantly, what they do not — so decisions made now rest on the law as passed rather than on headlines. Division 293 tax rounds out the set for higher earners whose super contributions attract the extra 15%.
Every resource in the collection is date-stamped three ways: the financial year it applies to, the date it was published or last modified, and the date its sources were last verified against the ATO, Treasury or the legislation itself. When a rate or threshold changes, the resource changes with it and superseded material moves to the archive. If you are new here, start with the current-year rates resource, then follow the related links each page suggests — and when a rule clearly touches your own position, that is the point to talk to the practice rather than keep reading.
