澳洲负扣税计算器

计算负扣税带来的节税:当租金支出超过租金收入时,亏损可从其他应税收入中扣除。

这是什么工具?

负扣税指投资房产的利息与运营支出超过租金收入。亏损可从未他应税收入中扣除,从而降低应纳税额。本工具仅模拟所得税影响。

运作原理

输入租金收入、租金支出与其他应税收入。

How the tax saving arises

Negative gearing only changes your income tax. If expenses exceed income, the loss is deducted from your other taxable income, so you pay tax on a smaller amount. The saving equals the loss multiplied by your marginal rate.

With gearingOther income − rental loss

What this tool does not cover

It models the income-tax effect only. It does not include capital gains tax on a future sale, land tax, state stamp duty on purchase, or the cash-flow gap (you may still pay out of pocket each year).

Not coveredWhy
Capital gains taxA separate CGT event when the property is sold
Stamp duty & land taxState-based purchase and holding taxes
Cash flowThe property may still cost you out of pocket each year

Changes from 1 July 2027

From 1 July 2027 negative gearing of residential property is limited to new builds. Properties held at 7:30pm AEST on 12 May 2026 are exempt, so existing investors are unaffected; the limitation applies to established dwellings acquired after that time, whose losses can be offset only against residential property income and residential capital gains (excess losses may be carried forward). New builds can still be negatively geared. This tool shows the rules as they stand today and does not model the post-2027 limitation.

常见问题

哪些算作租赁支出?

贷款利息、维修、管理费、市政费、保险和折旧是常见的可抵扣支出。资本性工程(capital works)和本金还款不可抵扣。

节省额就是全部亏损吗?

不是。节省额等于亏损乘以你的边际税率,因为只有那部分收入对应的税被避免。

会影响资产出售吗?

此处不直接影响。抵扣导致较低的成本基础可能抬高未来的资本利得,这属于单独的 CGT 事项。
