ATO Logbook Requirements in 2026: WhatEvery Australian Driver Needs to Know

And why choosing the right logbook app matters more than ever

If you use your car for work purposes and want to claim vehicle expenses on your
Australian tax return, keeping an ATO-compliant logbook is not optional — it is
essential. Yet every year, thousands of Australians either miss out on legitimate
deductions or face ATO scrutiny because their logbook records are incomplete,
inaccurate, or simply missing.

This guide walks you through exactly what the Australian Taxation Office requires for
a valid logbook, how the system works, common mistakes to avoid, and how modern
apps like CarSavvy make the whole process effortless — and fully ATO-compliant.

What is the ATO Logbook Method?

The ATO allows two methods for claiming car expenses: the cents-per-kilometre
method and the logbook method. The logbook method is almost always more
advantageous for anyone who drives more than 5,000 kilometres for work per year,
or who has a higher-value vehicle.

Under the logbook method, you calculate the percentage of your total car use that
was for work purposes over a continuous 12-week period. This percentage then
applies to all your actual car running costs — including fuel, insurance, registration,
servicing, depreciation, and loan interest — for the entire financial year.

Example: If your logbook shows 60% business use, and your total annual car costs
are $12,000, you can claim $7,200 as a tax deduction. The savings are significant —
and the only barrier is maintaining a proper logbook.

What Does the ATO Require in a Valid Logbook?

The ATO is very specific about what constitutes a valid logbook. Under section 900-
C of the Income Tax Assessment Act 1997, a compliant logbook must record the
following for every work-related trip:

• The date the trip was made
• The odometer reading at the start of the trip
• The odometer reading at the end of the trip
• The number of kilometres travelled
• The reason for the trip (the business purpose)

In addition, the logbook itself must meet these overall requirements:

• It must cover a continuous period of at least 12 weeks
• It must record the odometer reading at the start and end of the 12-week period
• The 12-week period must be representative of your typical work travel pattern throughout the year
• Once established, a logbook is valid for five years — provided your work travel pattern does not change significantly
• If your circumstances change (e.g., new job, different role, different travel patterns), you must start a new logbook

Important: The ATO may request your logbook during an audit. Digital logbooks are
fully accepted, provided they contain all required fields. Handwritten logs on paper
are still valid but are far more error-prone and easily lost.

The Five-Year Rule: How Long Does a Logbook Last?

One of the most misunderstood aspects of the logbook method is how long a logbook remains valid. A single 12-week logbook can be used for up to five income years — but only under specific conditions.

Your logbook stays valid across five years if:

• Your work travel pattern has not changed substantially
• You keep odometer records at the start and end of every financial year
• The vehicle is still the same (or substantially similar in use)

You must start a new logbook if:

• You change jobs or your duties change, altering how much you drive for work
• You start using a different vehicle
• Your business-use percentage is likely to have changed significantly

This makes the initial 12 weeks critically important. Accurate records during that period set your deduction percentage for up to five years — making precision during this window extremely valuable.

What Counts as a Work-Related Trip?

Not all driving to or from a workplace qualifies as work-related travel. The ATO distinguishes between ordinary home-to-work commuting (which is generally not deductible) and legitimate work-related travel.

Travel that generally qualifies as work-related includes:

• Travel between two separate workplaces (e.g., visiting a client site from your regular office)
• Travel to perform work duties away from your regular workplace
• Travel from home to an alternative workplace when you are not travelling to your regular workplace that day
• Travel carrying bulky tools or equipment that cannot be stored at the workplace
• For rideshare and delivery drivers: all trips made while carrying passengers or goods for payment

Travel that generally does not qualify:

• Daily commuting from home to a fixed regular workplace and back
• Personal errands, even if done in a work vehicle
• Travel between home and work where the only reason it is inconvenient is the distance

Pro tip: Always record the specific business purpose for each trip — not just ‘work’. The more descriptive your entries, the stronger your records are if ever queried by the ATO.

Common Logbook Mistakes That Can Cost You

Even diligent drivers make errors that can invalidate their logbook or reduce their claimable percentage. Here are the most common pitfalls:

1. Incomplete trip records. Missing even a few required fields (like the business purpose) can call your entire logbook into question.
2. Not covering the full 12-week period. If your logbook period is shorter than 12 continuous weeks, it is not valid.
3. Missing odometer readings. You need both the start-of-period and end-of-period odometer totals, plus readings for each trip.
4. Not updating after a major change. Using an old logbook after changing jobs or vehicles is a common audit risk.
5. Poor record of business purpose. Writing ‘business’ is not sufficient. Note the client, location, or task involved.
6. Forgetting odometer records each financial year. Even with a valid five-year logbook, you still need to record odometer readings at 1 July and 30 June each year to calculate your annual business use fraction.

Why a Logbook App Is Now the Smart Choice

Paper logbooks were once the only option. Today, they are also the riskiest. They can be lost, damaged, or left at home on the day you need them. Entries are easily forgotten, especially for frequent drivers.

A dedicated logbook app solves all of these problems — and adds capabilities that paper simply cannot offer:

• Automatic trip detection means you never forget to log a trip
• GPS-based distance recording is more accurate than guessing or relying on odometer checks
• Digital storage means your records are always accessible and backed up
• Instant report generation makes tax time fast and straightforward
• ATO-compliant formatting ensures nothing is missing

Not all logbook apps are created equal, however. The right app should be genuinely effortless to use, cover all ATO requirements, and ideally go beyond just trip logging to help you manage and maximise your entire vehicle-related claim.

CarSavvy vs Driversnote: Which Logbook App Is Right for Australian Drivers?

Two of the most widely used logbook apps available to Australian drivers are CarSavvy and Driversnote. Both offer automatic trip tracking and ATO-compliant records. But there are meaningful differences that matter when you look closely — particularly if you want more than just basic mileage logging.

Here is a detailed, feature-by-feature comparison:

Setup and ease of use

One of the most immediately noticeable differences is how quickly each app gets you up and running. CarSavvy follows a genuinely instant setup — download the app, enter your vehicle’s registration number, and you’re tracking. There is no waiting for hardware to arrive in the post.

Driversnote, by contrast, offers its most seamless automatic tracking through an optional Bluetooth beacon — a small physical device you attach to your car. This beacon improves trip auto-detection significantly, but it costs extra and requires you to wait for delivery before you can fully configure the app. For anyone who wants to start logging immediately, this is a meaningful friction point.

Expense tracking — a critical difference

Here is where CarSavvy meaningfully outperforms Driversnote for Australian taxpayers. The logbook method is not just about kilometres — it’s about documenting your total vehicle running costs so you can claim the right percentage. That means fuel, servicing, insurance, registration, tyres, and any other car-related expenses.

CarSavvy includes built-in expense tracking with AI-powered receipt capture. You photograph a receipt, and the app extracts and categorises the relevant details automatically. At tax time, your expense log is ready alongside your trip log — giving you a complete picture of your claim, this feature is also completely free.

Rideshare driver support

For rideshare and delivery drivers — a growing segment of the Australian workforce — CarSavvy’s dedicated ‘Shifts’ mode is a major advantage. This mode is specifically designed for drivers who pick up and drop off passengers or goods for hours on end. Making it straightforward to track work periods separately from personal driving.

Driversnote does not cater to rideshare scenarios, which can make logging more complex for drivers in the gig economy.

Vehicle management beyond the logbook

CarSavvy takes a broader view of car ownership. Beyond trip logging and expenses, it includes tools for tracking registration due dates, insurance renewals, and service intervals. There is even a fuel finder to help locate the best nearby fuel prices.

For drivers who want a single app to manage the financial and administrative side of vehicle ownership — not just their ATO logbook — CarSavvy is a considerably more complete solution.

Pricing

CarSavvy offers a free forever basic tier that provides genuine ongoing value without a time limit. Paid plans start at approximately $5–6 per month on an annual basis.

Driversnote’s free tier is capped at 15 trips per month — which is quickly exhausted by regular commuters or business drivers. The paid plan runs to approximately $17 per month, and that does not include the cost of the optional Bluetooth beacon hardware.

For drivers conscious of subscription costs, CarSavvy’s pricing structure is considerably more accessible, with more features included at every tier.

App ratings and track record

Driversnote has a long history in the market and carries a large volume of reviews — its 4.7-star iOS rating reflects years of user feedback and iteration. This is a genuine strength.

CarSavvy is a newer entrant to the market and currently has a smaller review base, though its rating is currently 4.8 stars on the Australian App Store. As with any newer platform, the review volume will grow over time. Early adopters are benefitting from a product that has been built with modern Australian drivers in mind from the ground up.

Our Verdict: CarSavvy Is the Best Logbook App for Most Australian Drivers

Both apps will help you meet your ATO logbook obligations. But if you want an app that does more than the bare minimum — one that tracks expenses, supports rideshare work, manages your vehicle, and does it all at a genuinely accessible price — CarSavvy is the clear recommendation.

The combination of instant setup, AI expense capture, full trip logging, vehicle management tools, and a competitive free tier makes CarSavvy particularly well-suited to:

• Employees who drive for work and want to maximise their tax deductions
• Rideshare and delivery drivers who need a purpose-built tracking mode
• Small business owners managing one or more vehicles
• Families or teams sharing vehicles who need multi-vehicle support
• Anyone who wants a single app to handle all aspects of vehicle cost management

Getting Started: Your ATO Logbook Checklist

Ready to start keeping a compliant logbook? Here is a quick checklist to make sure you cover all the bases:

• Download a compliant logbook app (CarSavvy is free to get started)
• Note your odometer reading on the day you start your logbook period
• Log every trip for at least 12 continuous weeks, recording the date, start/end odometer, kilometres, and business purpose for each work trip
• Record your odometer reading at the end of the 12-week period
• Calculate your business-use percentage based on the period
• Keep receipts for all car expenses throughout the year — fuel, servicing, insurance, registration
• Record your odometer at 30 June and 1 July each year to maintain your five-year logbook validity
• Review your logbook at the start of each financial year to confirm your circumstances haven’t changed

Tax deductions for vehicle expenses can be substantial. The difference between a carefully maintained logbook and a rough estimate can easily amount to hundreds or even thousands of dollars in additional refunds each year. Getting the process right — and using a tool that makes it effortless — is one of the highest-return habits any working Australian driver can adopt.
