Residential Rental Loans – Interest Deductibility, Offset & Redraw Facilities

Lewis Thomas • September 17, 2024

One of the most common incorrectly claimed deductions against rental property income is interest . If you borrow to purchase a rental property any interest you incur on that loan will generally be tax deductible. But what if that loan has a redraw facility – what happens if redraw against the loan balance?  Is the interest still tax deductible?  The answer – it depends!

In this instance every transaction needs to be considered because if the redrawn amount is used for private purposes , then the interest deduction needs to recalculated to take into account the now private portion of the loan.

Example :

Bill has borrowed $400,000 to purchase a rental property. The property is rented for the entire duration of the loan. After 10 years the loan has been paid down to $200,000. Bill then decides to redraw a further $200,000 to pay off a second loan not related to the rental property. Now, only 50% of Bill’s loan relates to the rental property. Consequently, only 50% of the interest component will now be deductible against the property’s rental income. This takes effect for remaining life of the loan or until another draw down or re financing has been made.

Every time a redraw transaction is used for a private purpose, the deductible portion of the loan interest must be adjusted.

This is important to consider when thinking about re-drawing to pay for everyday costs such as groceries and bills, as it will continue to result in a lower interest deduction.  There are 2 ways this issue can be addressed, so you can continue to maximise your loan interest deduction:

  1. Do not use your redraw facility to pay for private expenses – not always an easy option.
  2. Use an offset account rather than a redraw account.

An offset account is a completely separate account which can be used to accumulate savings and excess cash reserves.  The beauty of an offset account is it works exactly the same way as a redraw facility, as the balance of the offset account is used to reduce the loan balance when calculating interest.

The main difference though is when you withdraw money from your offset account, regardless of whether this is for a private purpose, it does not affect your ability to claim any interest deduction on the loan.  This also means you do not have to do calculations each time a private withdrawal from the offset account (as you would with a redraw facility).

It’s common to inherit land, shares or other investments and assume there won’t be any tax to think about. While inheriting an asset usually doesn’t trigger capital gains tax (CGT) straight away, CGT can become an issue later—particularly when you decide to sell. What affects the CGT outcome? · When the deceased originally acquired the asset (especially whether it was before or after 20 September 1985 ). · What the asset is (a home, an investment property, farmland, shares, a business asset, etc.). · Whether it was ever used to produce income (for example, rented out) or used in a business. · Who owned it and how (for example, owned jointly, or inherited through multiple generations). Questions we commonly ask (because the answers can change the result): · When did the deceased buy the asset? (And was it inherited from an earlier estate?) · Was the asset originally purchased with someone else (for example, a spouse or sibling)? · Was the asset used in a business (and could any small business CGT concessions apply)? As a general rule, there’s usually no CGT event when you inherit an asset . However, if you sell the inherited asset later, CGT may apply—and the calculation often depends on when the deceased acquired the asset and how it was used . If the inherited asset is a home: the main residence exemption may still apply after the owner’s death, but it can depend on things like when the deceased moved out, whether the property was rented, and who lived in the property after death. Cost base (the starting point for CGT): for many inherited assets, your cost base will depend on whether the deceased acquired the asset before or after 20 September 1985 . In broad terms, if the asset was owned by the deceased before that date, the cost base is often the market value at the date of death . If it was acquired after that date, the cost base is generally carried over based on the deceased’s position (with adjustments in some cases). Where the asset is connected to a business, small business CGT concessions may be relevant. If you’re thinking about selling something you inherited, it’s worth getting advice early—before contracts are signed—so we can confirm what records you’ll need and what the CGT position is likely to be.

It is Federal Budget night on May 12 and even though you may not be an excited accountant or tax agent counting down the days, if you are an investor, it is likely there will be changes announced which will impact you. The change which is likely to be unveiled will be the Albanese Government’s approach to capital gains tax, targeting mainly share and property investors, but will also impact business owners who sell business assets. It is likely the Albanese Government will re-introduce an inflation indexation model for calculating capital gains tax. This proposed change has gained more traction in the media over the last few weeks. Currently, individual taxpayers and trust beneficiaries are able to reduce their capital gains tax on the sale of any capital investment by 50 per cent, providing this investment has been owned for at least 12 months. Please note – superannuation funds receive only a one-third discount. For an individual, this means half the gain is tax free, the remaining half of the gain is taxed at the taxpayer’s marginal tax rate. This discount system on capital gains has been in place since 1999. Capital gains tax (CGT) was introduced in 1985 and is applied to realised gains and losses on assets acquired after 19 September 1985. If an asset was purchased prior to the introduction of CGT, then it is exempt from CGT when sold. From 1985 to 1989 an indexation system was used where inflation factors were applied to the original cost, so only the “real/after inflation” gain was taxed. At this stage there has been no indication whether the changes, if introduced, would be grandfathered, to spare existing investors from any initial pain.

Keeping a car logbook is an important part of managing your vehicle expenses, especially if you’re looking to maximise your tax deductions and GST claims or reduce your FBT liability. The Australian Taxation Office requires you to keep a logbook for a minimum continuous period of 12 weeks to establish your business-use percentage. Each trip should include the date, start and end times, kilometres travelled, and the purpose of the journey. Your logbook needs to reflect your typical vehicle use and can generally be relied on for up to five years, as long as your usage doesn’t significantly change. You’ll also need to record your vehicle’s odometer readings at the start and end of each FBT year and financial year. For many small business owners and tradies, keeping a car logbook is necessary but often pushed aside during busy workdays. Manually recording trips can be time-consuming, and it’s easy to forget details after the fact. There are now several apps available that reduce the manual effort of keeping a logbook. One we often recommend, which complies with ATO requirements, is Driversnote. Driversnote is designed to simplify the process by using GPS tracking to automatically record trips. This helps ensure journeys are logged consistently without relying on manual entry. Trips can be easily categorised as business or personal, and the app generates reports that align with ATO logbook requirements. This can make it easier to stay organised and provide accurate information at tax time. The app also stores data securely and keeps a history of trips, which can be useful if you ever need to review your records. For those who regularly use their vehicle for work, tools like Driversnote offer a practical way to maintain a logbook without the usual hassle—helping keep everything accurate, organised, and in one place. If you’re unsure whether a logbook is right for your situation, contact us— one of our team can help you work out the best way to track your vehicle use and ensure your records are accurate for FBT and tax time.

The Federal Government has once again extended the $20,000 instant asset write-off , providing continued support for small businesses looking to invest and grow. Under the latest legislation, eligible businesses can access the $20,000 threshold for assets first used or installed ready for use between 1 July 2025 and 30 June 2026 . This extension means businesses can continue to immediately deduct the full cost of qualifying assets, rather than depreciating them over several years. How the write-off works The instant asset write-off allows small businesses with an aggregated turnover of less than $10 million to claim an immediate deduction for assets costing less than $20,000 (excluding GST). The threshold applies on a per-asset basis , meaning multiple assets can be written off, provided each individual item is under the limit. Eligible assets can include tools, equipment, vehicles (subject to other limits), and office technology. Both new and second-hand assets may qualify, provided they are used for a business purpose. A critical point often missed is timing. It’s not enough to purchase an asset before 30 June— it must be installed and ready for use by that date to qualify for the deduction. What happens to assets that are above $20,000? If an asset exceeds the $20,000 threshold, it cannot be immediately written off in full. Instead, it is allocated to the small business general depreciation pool and depreciated over time. Under current rules, assets in this pool are typically depreciated at 15% in the first year and 30% in each subsequent year (on a diminishing value basis). This means the tax deduction is spread across multiple years rather than claimed upfront. Why the extension matters This measure continues to deliver meaningful cash flow benefits. By bringing forward deductions, businesses can reduce taxable income in the current year, freeing up funds for reinvestment or day-to-day operations. However, the extension is temporary. From 1 July 2026 , the threshold may revert back to just $1,000 unless further legislation is passed.  This ongoing uncertainty makes forward planning essential so talk to your accountant today to plan ahead.
