Question 1

How accurate are the dollar estimates?

Accepted Answer

Quantifiable estimates use central tax-year configs (ATO + Budget 2026-27 Treasury papers). The $1,000 instant deduction is computed at your marginal rate; the $250 Working Australians Tax Offset is the flat amount from 2027-28; 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 (negative gearing reform, CGT discount reform, trust minimum tax, FBT EV reform, permanent IAWO) are listed as watch items with links to the dedicated calculators rather than guessed at.

Question 2

Why aren't negative gearing and CGT reform shown as dollars in the headline?

Accepted Answer

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.

Question 3

When do the measures take effect?

Accepted Answer

The $1,000 Instant Tax Deduction starts 1 Jul 2026. The $250 WATO starts 1 Jul 2027. The Medicare levy threshold uplift is retroactive to 1 Jul 2025 (applies to your 2025-26 return). The fuel excise cut runs 1 Apr to 30 Jun 2026. Negative gearing reform commences 1 Jul 2027 (existing properties grandfathered). CGT discount reform commences 1 Jul 2027 (split treatment for assets held at that date). The 30% trust minimum tax commences 1 Jul 2028. FBT EV transition runs 1 Apr 2027 to 1 Apr 2029, then permanent.
