Usually not for your own home — it depends on the purpose

Can I claim interest deductions if I refinance to release equity for renovations?

Usually not if the renovation is on your own home — because interest deductibility follows the purpose the money is used for, not the equity you draw it from. Releasing equity to renovate your owner-occupied home is a private purpose, so that interest is generally not deductible. If the renovation is on an income-producing investment property, the interest on the released equity generally is deductible. The property the loan is secured against does not decide it — the use does.

The trap most brokers miss

The trap is assuming that because the equity came from an investment property, the interest must be deductible. It is the reverse: draw equity from your investment loan to renovate your own home, and that interest is not deductible — and it can contaminate the rest of the loan if not split. Getting this wrong quietly costs deductions every year.

How it plays out

Illustrative scenarios

Teaching examples built from typical situations to show how we approach the problem. Numbers only, never names.

Illustrative scenario

Equity release for renovations

The situation

An owner wanted to redraw $80,000 from their home loan to renovate, and asked whether the interest would be deductible.

The challenge

Interest on money redrawn for a private renovation on an owner-occupied home is generally not deductible — a common and costly misunderstanding.

Our approach

We explained that deductibility follows use, set expectations honestly, and where an investment purpose was involved structured a separate split to keep any deductible portion clean.

The illustrative outcome

The owner proceeded with a clear, honest understanding of what was and was not deductible — an illustration of avoiding a costly assumption before it happened.

Illustrative scenario

Refinance and interest deductibility

The situation

An investor wanted to refinance an investment loan and release $100,000 of equity, unsure whether it would affect the interest deductions on the existing loan.

The challenge

Deductibility follows the PURPOSE the borrowed money is used for, not the property it is secured against — mixing the equity release with the investment loan risked contaminating the deduction.

Our approach

We structured the equity release as a separate split and documented its purpose, so the deductible and non-deductible portions stayed cleanly divided.

The illustrative outcome

The refinance proceeded with the deduction trail kept clean — an illustrative example of structure protecting a tax position, discussed with your accountant.

Common questions

More on this problem

Only if the renovation is on an income-producing property. Renovating your own home with borrowed funds is a private purpose, so the interest is generally not deductible. Renovating an investment property you rent out generally makes that interest deductible — the use decides.
Australian tax law tests deductibility on what the borrowed money is used for, not which asset secures the loan. Borrowing against your home to invest can be deductible; borrowing against your investment property for a private renovation is not. This purpose test catches many borrowers by surprise.
Keeping the equity release in its own loan split with a documented purpose prevents deductible and non-deductible borrowing being mixed in one account. A mixed-purpose loan is hard to untangle and can jeopardise legitimate deductions, so the split keeps the trail clean.
