Budget 2026 will materially damage efficient capital formation in Australia.
“the 2026 Budget ... will destroy efficient capital formation in Australia.”
This is a strong macroeconomic forecast rather than a source-text fact. The Budget clearly changes the taxation of post-2027 gains and therefore the after-tax attractiveness of some founder, share, and business outcomes. But whether that rises to 'destroying efficient capital formation' depends on behavioural responses, substitution into other assets, the role of small-business concessions, and whether offsetting venture-capital and startup-support measures preserve some of the investment case.
Assumptions required
- Assumes the CGT redesign is a major determinant of capital allocation decisions in the affected sectors.
- Assumes investors and founders do not substantially offset the change through concessions, structures, or other asset choices.
- Assumes the Budget's startup and venture-capital support measures do not materially cushion capital formation.
Alternative defensible framings
- The redesign may weaken some forms of productive capital formation, but the size of the effect is still uncertain.
- The policy changes after-tax incentives; whether that meaningfully impairs capital formation is a broader empirical question.
