Bright-Line Test

Will your sale trigger income tax?

Find out instantly whether your property sale falls within the bright-line period and could be subject to income tax.

What is the bright-line test?

The bright-line test is a rule that taxes profit from selling residential property if you sell within a set number of years of purchase. It applies regardless of your intention when you bought the property.

The period has changed several times: properties purchased from 1 July 2024 are subject to a 2-year bright-line period. Properties purchased between 27 March 2021 and 30 June 2024 are subject to a 10-year period (5 years for new builds). Earlier purchases have shorter periods.

If your sale falls within the bright-line period, any profit is treated as taxable income and taxed at your marginal rate. The main home exclusion may apply in some circumstances — see below.

The date you settled on the property purchase.

Defaults to today. Change to a future date to plan ahead.

New builds purchased between 27 March 2021 and 30 June 2024 have a 5-year bright-line period instead of 10 years.
