澳大利亚新房产税改将于2027年生效：投资者税负影响各异

澳大利亚联邦政府将从2027年7月1日起实施重大房地产税改革1。改革内容包括三项关键变化：负向租赁收入损失不再可用于抵扣非投资收入、现行50%资本利得税折扣将被基于通胀的扣除制度替代，以及引入30%最低资本利得税率1。

基于2007年7月至2025年6月期间920000项房产数据的研究模型表明，新税改对投资者的影响并不一致1。约53%的房产投资在新税制下总税负会增加，而47%的投资总税负将维持不变或降低1。资本利得税政策调整产生的影响大于负向租赁规则改变1。

税改带来的影响在不同投资者群体间存在显著差异1。资本利得排名前20%的投资，平均资本利得税增幅约为购买价格的11%，而底部60%的投资平均资本利得税反而下降3至4%1。约50%的房产投资存在负向租赁情况1。新的30%最低资本利得税率对低收入年份出售房产的投资者影响最为严重，这类投资者中退休者占比较高1。高杠杆房产投资者将受到最严重影响1。

Australia's federal government will implement significant changes to property investment taxation starting July 1, 2027, fundamentally altering how capital gains and rental losses are taxed 1. The reforms introduce three major changes: negative rental income losses will no longer be deductible against non-investment income, the 50 percent capital gains tax discount will be replaced with an inflation-adjusted deduction system, and a new 30 percent minimum capital gains tax rate will be introduced 1.

A research model based on 18 years of data covering 920,000 properties reveals that approximately 53 percent of property investments will face higher total tax burdens under the new regime, while 47 percent will experience unchanged or reduced tax liabilities 1. The impact of capital gains tax changes will significantly outweigh the effects of the negative rental loss restrictions, with about 50 percent of investments currently qualifying as negatively geared 1. For properties with the highest capital gains—the top 20 percent—investors will see average capital gains tax increases equivalent to approximately 11 percent of the original purchase price 1. Conversely, properties with the lowest capital gains in the bottom 60 percent will experience average tax reductions of 3 to 4 percent 1.

The minimum 30 percent capital gains tax rate will disproportionately affect investors who sell properties during low-income years, typically retirees, as well as those with high-leverage property portfolios 1.
