Bright-Line Calculator Interest Deductibility Property Sale Tax TriggersBright-Line Test
The bright-line test taxes profits on residential property sold within a defined holding period. For properties sold on or after 1 July 2024, the bright-line period is 2 years, regardless of when the property was purchased.
| Sale Date | Bright-Line Period | Notes |
|---|---|---|
| On or after 1 July 2024 | 2 years | Current rule, applies regardless of purchase date |
| 27 March 2021 to 30 June 2024 | 10 years (5 years for new builds) | Historical rule for sales before 1 July 2024 |
| 29 March 2018 to 26 March 2021 | 5 years | Historical rule |
| 1 October 2015 to 28 March 2018 | 2 years | Original rule |
| Before 1 October 2015 | Not applicable | Pre-bright-line era |
The bright-line start date is generally the settlement date (when title transfers to you). The end date is the date the sale and purchase agreement is signed. Profits are taxed at your marginal income tax rate (up to 39%).
Main Home Exclusion
The main home exclusion removes a property from the bright-line test if it was used as your main home. Rules depend on when the property was acquired:
| Acquisition Date | Test Applied |
|---|---|
| On or after 1 July 2024 | Exclusion applies if property used as main home for more than 50% of the bright-line period |
| 27 March 2021 to 30 June 2024 | Predominant use test: apportioned exclusion for periods where not used as main home |
| Before 27 March 2021 | All-or-nothing: full exclusion if used as main home for more than 50% of ownership |
More than 50% of the land area (including yard, gardens, and garage) must have been used for private residential purposes to qualify as a main home.
Interest Deductibility (Rental Property)
From 1 April 2025, 100% of interest on funds borrowed for residential rental property is deductible, ending the phased restrictions that applied from October 2021.
| Income Year | Interest Deductible (Existing Properties) | Interest Deductible (New Builds) |
|---|---|---|
| 2026/27 (1 Apr 2026 to 31 Mar 2027) | 100% | 100% |
| 2025/26 (1 Apr 2025 to 31 Mar 2026) | 100% | 100% |
| 2024/25 (1 Apr 2024 to 31 Mar 2025) | 80% | 100% |
| 2023/24 | 50% | 100% |
| 2022/23 | 75% (pre-27 Mar 2021) / 0% (post) | 100% |
| 2021/22 (from 1 Oct 2021) | 100% (pre-27 Mar 2021) / 0% (post) | 100% |
New builds: Properties with a Code Compliance Certificate (CCC) issued on or after 27 March 2020 qualify as new builds and were always exempt from the interest limitation rules.
Ring-Fencing of Rental Losses
Rental losses are "ring-fenced" and cannot be offset against other income (salary, business income, etc). This rule applies regardless of interest deductibility changes.
| Rule | Detail |
|---|---|
| Can offset against | Other residential rental income only |
| Cannot offset against | Salary, wages, business income, capital gains |
| Carry forward | Unused losses carry forward indefinitely |
| On sale | Released only if sale is taxable (e.g. under bright-line test) |
Mixed-Use Asset Rules (Holiday Homes, Baches)
The mixed-use asset rules apply when a property is used both privately and to earn income, and is unused for 62 or more days in the year.
| Test | Rule |
|---|---|
| Trigger threshold | Asset unused for 62+ days in the income year |
| Also applies to | Boats and aircraft costing $50,000+ |
| Expense apportionment | Deduction formula: income days / (income days + private days) |
| Opt-out option | Available if gross income less than $4,000 or expenses less than $0 (deemed no income) |
Chattels Depreciation
Depreciation on the residential building itself is 0% (since 2011). However, chattels (removable items not part of the building) can still be depreciated.
| Chattel Type | Typical Depreciation Rate (DV) |
|---|---|
| Carpets | 33% |
| Curtains and drapes | 25% |
| Furniture (freestanding) | 20% |
| Heat pumps | 20% |
| Whiteware (fridge, washing machine, stove) | 20% |
| Hot water cylinders | 20% |
| Light fittings | 13.5% |
| Low-value assets (under $1,000 each) | 100% in year of purchase |
Other Land Sale Rules
Even if a sale is outside the 2-year bright-line period, other land sale rules under the Income Tax Act 2007 can still tax the profit:
| Section | Rule |
|---|---|
| s CB 6 | Land acquired with purpose or intention of disposal |
| s CB 7 | Land acquired as part of a business of land dealing |
| s CB 8 | Land developed for sale (10-year rule) |
| s CB 9 | Land sold within 10 years by land dealer |
| s CB 10 | Land sold within 10 years by developer or builder |
| s CB 12 | Land developed or subdivided within 10 years of acquisition |
| s CB 13 | Land with significant development or subdivision work |
| s CB 14 | Land sold after zoning change or other public work |
GST and Residential Property
