What Is Interest Limitation?
If you have a new build or another property that gets an exemption (social housing, some subdivisions, one house into two, and others), we can claim 100% of the interest as a tax deduction, reducing taxable profit and tax.
Let's take a look at some concrete examples to illustrate how this can work in practice:
New Build:
- Rent $35,000
- Other expenses (Property management, rates, insurance, accounting, repairs etc) $10,000
- Chattels depreciation $5,000
- Interest $30,000
- Net Profit (loss) $(10,000).
As a loss, there is no tax to pay.
If you purchased an existing house as a rental now and don't qualify for one of the exemptions, 0% of interest is claimable under the current Interest Limitation rules.
Existing Home:
- Rent $35,000
- Other expenses (Property management, rates, insurance, accounting, repairs etc) $13,000
- Chattels depreciation $2,500
- Interest $30,000
- Net Profit (loss) $(10,500).
However, because of the Interest Limitation in this scenario, we cannot use the interest as a deduction. As a result, we end up with a Taxable Profit of $19,500.
If your tax rate is 33%, you would owe $6,435 in taxes. Excluding depreciation since it's not a cash expense, you'd be facing a cash loss of $8,000, in addition to paying the $6,435 in taxes. So, overall, you'd be looking at a yearly loss of $14,435.
It's important to note that all these calculations are based solely on interest payments, with no part of the loan going towards repaying the principal. If you were repaying the principal, it's worth mentioning that this portion also cannot be claimed as a tax deduction.

Lifetime Book Club: Paradox of Choice by Barry Schwartz
In The Paradox of Choice, psychologist Barry Schwartz explores a curious feature of modern life: while freedom and choice are undoubtedly valuable, there can come a point where having more options makes decisions harder, increases our expectations and leaves us questioning whether we made the right choice at all.
From what to buy and where to eat to decisions about careers, relationships and money, Schwartz looks at the hidden mental cost of constantly comparing our options – and makes the case that sometimes, simplifying our choices can leave us better off.
