Compare your annual tax under the current system with the Green Party's proposed changes. Enter your income and net wealth (excluding your family home) to see how you would fare.
Each point represents a combination of income and wealth. Green = better off under the proposal; red = worse off. Intensity reflects the magnitude of the impact. The income axis is capped at ~$200k (top 1% individual income threshold, Stats NZ / IRD); the wealth axis runs to $10.5M, just past the $10M wealth tax threshold and covering approximately 99.8% of taxpayers. Horizontal markers show where the top 10%, 1%, and 0.5% individual wealth thresholds fall. The dashed vertical line marks the income break-even (~$161k), and the dashed horizontal line marks the $10M wealth tax threshold.
* Income axis capped at ~$200k (top 1% individual income — IRD / Stats NZ). Wealth axis runs to $10.5M, just past the $10M wealth tax threshold; the narrow red band on the right edge shows its immediate impact. Wealth percentile thresholds from Stats NZ Oct 2025 (top 10%: $1.46M, top 1%: $4.74M, top 0.5%: $7.19M). The ~99.8% coverage figure is an estimate — granular data above the top 1% is not published by Stats NZ. Capital acquisitions tax (event-based) and ACC levy (unchanged under both systems) are excluded.
