Miners Push for CGT Exemption on Exploration
Mining executives and industry groups are lobbying the federal government to exempt mineral explorers from planned capital gains tax changes.
Updated on Nov. 8, 2026 in Remote Work
Australian mining executives and industry groups are pressing the federal government to exempt mineral explorers from planned capital gains tax reforms. The government confirmed in September that exploration companies will not receive the same treatment granted to technology start-ups.
Why it matters
Industry leaders argue the reforms would discourage investors from backing early-stage discoveries at a time when greenfields exploration in Australia is declining. The Minerals Council of Australia says the reforms fail to recognise the high risks and low success rates of mineral exploration.
The reforms replace the 50% CGT discount with cost base indexation and a 30% minimum tax on gains, effective 1 July 2027. Whether exploration companies will receive any carve-out remains unresolved as consultation continues.
The players
Jim Chalmers
Australia's Treasurer, who announced the capital gains tax reforms in the May 2026 federal budget.
Minerals Council of Australia
The national peak body representing Australia's minerals industry, which argues the reforms ignore the high risks and low success rates of exploration.
The details
The May 2026 federal budget, announced by Treasurer Jim Chalmers, set out the changes. Technology start-ups were granted exemptions, but the government confirmed in September that exploration companies would not receive the same treatment, prompting the lobbying push from industry.
Timeline
May 2026: Federal budget announces the capital gains tax reforms.
September 2026: Government confirms exploration companies will not receive the start-up exemption.
1 July 2027: Capital gains tax reforms take effect.
Market Landscape
The reforms replace the 50% capital gains tax discount, a longstanding feature of Australia's tax system, with cost base indexation and a 30% minimum tax. Exploration companies face the question of whether they will be treated like technology start-ups, which the government has so far ruled out.
For investors backing early-stage mineral exploration, the reforms could change the after-tax return on capital gains from new discoveries. Retail investors holding exploration stocks should watch the outcome of consultation, since it will shape how those gains are taxed from 1 July 2027.
The takeaway
The consultation may decide whether Australia can attract the risk capital needed to find its next generation of mines. Investors and industry should track the legislation closely as the 1 July 2027 start date approaches.
What happens next
The government has opened another round of consultation on the legislation, and its outcome will determine whether exploration companies receive any exemption before the reforms take effect on 1 July 2027.
