FAQ
How accurate are the dollar estimates?
Quantifiable estimates use central tax-year configs and enacted legislation. The $1,000 instant deduction is computed at your marginal rate. From 2027-28, WATO is the lesser of $250 and basic income tax on net labour income; this broad Budget tool treats taxable income as net labour income for work-income profiles. The Medicare levy retroactive uplift compares your 2025-26 liability under the new vs old shade-in thresholds. Fuel excise uses an 8.5 L/100km national average. Reforms that depend on asset-level inputs are listed as watch items with links to dedicated calculators rather than guessed at.
Why aren't negative gearing and CGT reform shown as dollars in the headline?
Both reforms require asset-level inputs (acquisition cost, rental loss, holding period, expected sale year) that this 60-second check doesn't ask for. Guessing a number from 7 inputs would mislead. Instead, the calculator flags these reforms as 'watch items' affecting you and routes you to the dedicated calculators (negative gearing calculator, CGT calculator) where the asset-level math is honest.
When do the measures take effect?
The core tax package is now law — passed 25 June 2026, royal assent 26 June 2026 (Treasury Laws Amendment (Tax Reform No. 1) Act 2026, Act No. 49 of 2026, with a companion Income Tax Rates Amendment Act No. 50 of 2026 imposing only the new 30% CGT minimum tax rate). The $1,000 Instant Tax Deduction applies from the 2026-27 income year. The $250 WATO applies from 2027-28 as a statutory formula. The Medicare levy threshold uplift is retroactive to 1 Jul 2025 (applies to your 2025-26 return). The fuel excise cut ran 1 Apr to 30 Jun 2026. Negative gearing reform commences 1 Jul 2027 (properties held at 12 May 2026 grandfathered). CGT discount reform commences 1 Jul 2027 (Subdiv 112-E deemed-sale split for assets held at that date, valued at 1 July 2027). The 30% trust minimum tax commences 1 Jul 2028. FBT EV transition runs 1 Apr 2027 to 1 Apr 2029, then permanent.
