Is it your Logbook Anniversary?

Janene Atfield • August 24, 2026

If you drive your car for work or business purposes, and want to claim a tax deduction, you must complete a valid logbook every five years; or sooner, if your typical business use has varied by more than 10%.

FBT legislation also requires a logbook, to ascertain the private versus business usage for all cars and many Utes that cost more than the luxury car tax threshold, or that don’t satisfy the ‘workhorse vehicle pre-requisites’. 

What is a valid logbook?

The ATO is very specific about what constitutes a valid logbook. Many logbooks fail under audit, due to lack of trip description, missing or incorrect odometer readings and/or insufficient weeks.

A compliant logbook must record the following for every trip:

  • vehicle make, model and registration number,     
  • when the logbook begins and ends,
  • the odometer reading at the start of the trip,
  • the odometer reading at the end of the trip,
  • the number of kilometres travelled for each journey,
  • the reason for the trip (the business purpose) or ‘private/pte’

 

The logbook must be kept over a continuous 12-week period and must be ‘typical’ of your usual work patterns/travel. A logbook can be transferred between vehicles, if the business usage is similar, and the logbook only applies to one vehicle at any one time.  

 

Common errors


Error: Insufficient trip descriptions - ‘Business’; ‘client’; ‘work’; ‘Lynten’

Correct: Accepted business/work reasons – ‘to town for parts’; ‘visit client for quote’; ‘to back paddock – fencing’; ‘to other farm - pump repairs’

 

Error: Logbook period only 6, 10 or 11 weeks

Correct: Must be for continuous 12-week period

   

Error: Odometer readings don’t agree e.g. last trip’s closing odometer reading - 95120; next trip’s opening odometer reading - 89175

Correct: Ensure every trip, both business and private, are recorded during that 12-week period

   

Error: Major change in business usage – like change jobs/retire/sell business or farm and/or markedly reduce business activity; and don’t complete a new ‘typical’ 12-week logbook period.

Correct: Complete a new full 12-week continuous logbook when business usage varies by more than 10% or every five-year anniversary, whichever earlier

   

Error: Forget to record the odometer reading at the beginning of every financial or FBT year.

Correct: Mark your calendar with a recurring 12-month reminder – ‘record od. reading’

 

The ATO are getting smarter

Logbooks are on the ATO’s radar. The ATO now has extensive data matching capabilities and can access tolls and social media pictures to review your logbook against actual trip destinations. They’ve been known to use handwriting experts and forensic document experts to verify the authenticity of the logbook e.g. if a logbook has been written in one sitting. And if an App, Word document or Excel spreadsheet has been used as the sole logbook record, they can access the audit trail, to assess what dates the entries were recorded.

 

Tax deductions and/or FBT savings for vehicle claims can be substantial and a valid logbook, along with the necessary expense substantiation, are vital forms of verification. Is it your Logbook Anniversary?

Many Australians don't know how their super fund has performed or what it invests in. Are you one of them? Here's what to check and why it matters. Do you know how your super fund performed over the last two years? Many Australians don’t and are working towards their financial future without fully understanding one of their most important assets and without a clear plan for how their super may support them in retirement. That's not surprising, as many people view super as something that should run quietly in the background while they're busy with careers, families and everything else that life throws at them. But when you’re not sure what’s happening behind your balance, it’s harder to know whether you’re on track, whether your current approach reflects your goals or what opportunities might be available to help you make the most of what you’ve built so far. Your super isn't sitting in an account, it's invested Super is invested by a fund on your behalf across a mix of assets, with those investments working to grow your balance over time. Those include: Shares Ownership in Australian and international publicly listed companies. Their value can rise and fall, sometimes substantially over short periods but shares can provide capital growth over the long term. Property and infrastructure Real assets like office buildings, shopping centres, airports and energy networks. They can produce income and don't always behave in the same way as share markets, helping diversify investment holdings. Fixed interest and bonds Lending to governments and companies in return for interest. They can provide regular income and be steadier than shares, although returns and risk vary depending on the investment. Cash Generally, the most stable and lowest risk investment type. It can provide stability and faster access to money but typically offers lower longer term return potential. The investment option you choose determines the mix of assets held in your super based on your risk appetite. Most super funds offer options from conservative to high growth. If you’re young, a growth option with a higher exposure to growth assets like shares could offer higher returns over time – but it also comes with higher risk. As retirement nears, you might want to consider a more conservative approach with more defensive assets, like bonds for example to protect your savings. If you've never made a choice, you're probably in your fund's default option, which is designed to suit a broad membership. It’s worth knowing whether the mix you're in matches your circumstances and goals, including how far you are from retirement. Why performance alone is not a true comparison If you're thinking about how your super compares, returns are often where people start. The trouble is that a return figure means nothing without context: What it's being compared to Growth and conservative options invest differently and with different levels of risk. Compare like with like or the comparison may not be genuine. The comparison period A single year can be heavily influenced by short term market conditions. Super is measured in decades, so five, seven and ten year returns tell you far more about whether a fund is consistently doing its job, albeit not a predictor of future performance. Fees and tax Published returns should reflect investment fees, costs and tax but administration fees may be charged separately from your balance. Two funds quoting the same return can leave you in meaningfully different places once all fees are accounted for. Then there are the things that returns can't show you at all. For example, what insurance is attached to your account and what it's costing you, whether the fund offers guidance, tools and advice or simply sends a statement once a year. Another consideration maybe the level of support available when you need it. When comparing funds, it's worth looking at the full picture, including performance, fees, investment options, retirement support and member benefits. What today’s decisions mean tomorrow To understand how your super stacks up, start here: Find your investment option It's on your annual statement and in your online account. Look at what's in it Your fund publishes the asset allocation (shares, cash etc.) for each investment option. Check the long-term return for that option Focus on five and ten year returns, not just last year and compare them with equivalent options. Understand the total cost Add together administration fees, investment fees and insurance premiums as an annual dollar figure. Comparing super is about working out which option will perform best for you. Before you jump in, it’s worth understanding what's behind the numbers so you can make decisions based on more than a headline return. Knowing where you stand is the first step A super balance tells you where you are today. Understanding how your super is invested, how it compares and whether it's aligned with your goals helps show whether you're heading in the right direction.

More Australians are choosing to take direct control of their retirement savings by establishing a self-managed super fund (SMSF) and according to the SMSF Association, Aussies now see their super as an important part of building and managing their overall wealth.
