Episode notes
Leverage GST To Raise Revenue
- Use New Zealand's broad GST as an anchor for revenue increases by adjusting the rate.
- Moving to European VAT levels could raise around four to five percentage points of GDP.
Incoherence In Capital Gains Treatment
- New Zealand's current capital gains treatment taxes some gains but leaves many out, breaking coherence with income tax principles.
- A consistent approach would include all gains by default and carve out specific exemptions.
Accrual Vs Realisation In CGT
- Taxing accrued (unrealised) gains aligns with comprehensive income but is rarely used due to practical difficulties.
- Realisation taxation creates hold‑on incentives and lets wealthy asset owners access lifestyles via borrowing against unrealised gains.
