How much will mortgage interest tax limitations affect you?

Use our handy calculator to work this out.


On Tuesday March 29, 2022, the Government passed the Bill which extended the Bright Line Test to ten years and remove ability of rental property owners to claim mortgage interest as a tax deduction.

Removal of mortgage interest as a tax deduction will be of particular concern to many rental property providers.

What are the tax changes?

Unless it is a new build or social housing rental, interest cannot be claimed as an expense from 1 October 2021 for rental property purchased on or after 27 March 2021.

For property acquired before 27 March 2021, interest deductibility on existing loans is being phased out over 4 years. Interest deductions for any new loans drawn down on or after 27 March 2021 is not allowed from 1 October 2021 onwards.
