Some lenders offer an interest in advance option on investment loans, where you prepay up to 12 months of interest, usually on a fixed rate. Investors sometimes use this to bring forward a tax deduction into the current financial year. Whether it suits you depends on your tax position, so it should be confirmed with your accountant. This is general information, not tax advice.
Written by Ross McFarlane, Licensed Mortgage Broker (Credit Representative 526725). About the authorInterest in advance is a feature some property investors use to manage the timing of their tax deductions. It is a tax driven strategy as much as a lending one, so here is a general explanation of how it works. It is not tax advice, and your accountant should confirm whether it suits you.
Interest in advance is an option on some investment loans where you prepay the interest for an upcoming period, often up to 12 months, in a single payment, rather than monthly. It is usually offered on a fixed rate, since the interest amount needs to be known in advance to prepay it.
The common reason investors use it is tax timing. By prepaying up to 12 months of interest before the end of the financial year, an investor may be able to bring that deduction into the current year rather than spreading it across the next. Whether this is beneficial depends entirely on the investor tax position.
Bringing forward a deduction is not automatically beneficial. It can help where an investor expects higher income this year than next, or wants to manage their taxable income in a particular year. In other situations it makes little difference or could be counterproductive. This is exactly why it is a question for your accountant.
Because the interest for the period must be known to prepay it, interest in advance is generally tied to fixing the rate for that period. That brings the usual fixed rate considerations, including less flexibility and potential break costs, which should be weighed alongside the tax timing.
Prepaying a year of interest in one payment requires having the funds available, so there is a cash flow consideration. The benefit is a potential tax timing advantage and sometimes a small rate discount for prepaying, weighed against tying up the cash upfront.
Interest in advance is offered by some lenders but not all, and the terms vary. So if this feature matters to you, it can influence which lender and product you choose, which is part of structuring an investment loan to suit your strategy.
Because this is fundamentally about tax timing, the useful step is to have your accountant confirm whether it benefits you, and a broker find a lender that offers it on suitable terms. A broker can do the latter, usually at no cost to you. This is general information, not tax or financial advice, and the ATO rules and your circumstances should guide the decision.

No. Bringing forward a deduction only helps in certain situations, such as expecting higher income this year than next. It is usually tied to fixing the rate and requires the cash upfront, so it should be weighed carefully.
