ChainCatcher 消息，澳大利亚正考虑对资本利得税（CGT）体系进行重大改革，计划用“通胀指数化”机制取代现行长期持有资产 50% 税收折扣政策，涵盖加密资产、股票等投资品类。现行制度允许个人持有资产超过一年后，仅对 50% 的资本利得部分计税，该政策自 1999 年实施。
若改革落地，投资者将改为依据通胀调整成本基准后再计算收益，在资产价格上涨较快时期，实际税负可能上升。根据提案逻辑，新机制将仅对“实际收益”（剔除通胀影响后的部分）征税，但在低通胀环境下，指数化抵扣幅度可能低于当前 50% 折扣，导致多数投资者税负增加。加密投资者影响尤为明显。
现行“持有即减税”机制强化长期持有（HODL）策略，而新方案将削弱时间持有优势，使高涨幅周期中的未实现收益税负显著提升。该提案仍处讨论阶段，预计将面临来自投资者群体及金融行业的强烈反对，争议焦点集中在资本形成效率与税制公平性之间的平衡。
