Fringe benefits tax on motor vehicles applies whenever an employer provides a car for an employee’s private use, and it is charged at a flat 47% on the grossed-up taxable value of that benefit. The tax exists to put employees who receive non-cash perks on roughly the same footing as those paid entirely in salary. Because the rate is high and the definition of “private use” is broader than most employers expect, small choices about how you document and value the benefit can move the annual bill by thousands of dollars.
What Counts as a Car and When FBT Is Triggered
Under the Fringe Benefits Tax Assessment Act 1986, a “car” is any vehicle designed to carry fewer than nine passengers (including the driver) and a load of less than one tonne. That catches sedans, hatchbacks, station wagons, most SUVs, and smaller commercial vehicles like many utes and vans that fall under the one-tonne threshold.1Australian Taxation Office. MT 2024 – FBT Dual Cab Vehicles The test looks at design, not use: a four-wheel-drive built for suburban driving is still a “car” even if it only ever sees worksites. Vehicles above either threshold, such as a single-cab ute rated at one tonne or more, sit outside the car rules entirely and are treated as residual fringe benefits with separate valuation.2Australian Taxation Office. Residual Fringe Benefits
FBT is triggered when a car is used privately or simply made available for private use. Home-to-work travel counts as private, even if the employee makes a brief work-related stop on the way.3Australian Taxation Office. How FBT Applies to Cars Weekend trips and personal errands count too.
The garaging rule catches a lot of employers off guard. If the car is kept at or near the employee’s home overnight, the ATO treats it as available for private use regardless of whether the employee actually drove it. It doesn’t matter that private use is forbidden, or that the car sits there for security reasons. Location decides availability, and FBT accrues for every day the car is parked at that address.4Australian Taxation Office. Car Fringe Benefits Tax – Private Use and Availability
The reverse also holds. Days when the car genuinely isn’t available reduce the taxable value: time in the workshop for repairs, weeks parked back at the business premises, or periods when the employee is overseas without access. Recording these days is one of the simplest ways to lower the final assessment.
Choosing a Valuation Method
Employers can choose between two methods to work out the taxable value of a car fringe benefit. Which one you pick, and how well you support it with records, is usually the biggest lever over the final cost.
Statutory Formula Method
This is the simpler option and the default for businesses without detailed running-cost records. Take the car’s base value (the price paid, excluding registration and stamp duty but including dealer delivery, fitted non-business accessories, and any GST or luxury car tax), multiply by 20%, then pro-rata for the number of days the car was available for private use.5Australian Taxation Office. Taxable Value of a Car Fringe Benefit Subtract any employee contributions.
Example: a $50,000 car (delivery and accessories included, registration and stamp duty excluded) is available all year, and the employee makes no contribution. Taxable value: $50,000 × 20% = $10,000. That figure then gets grossed up and taxed at 47%.
Operating Cost Method
The operating cost method values the benefit based on what the car actually costs to run, reduced by the business-use percentage from a valid logbook. For cars used mostly for work, it typically produces a much lower FBT bill than the statutory formula.
Total operating costs cover fuel, insurance, registration, repairs, maintenance, and tyres. On top of the actual outgoings, you add two deemed costs: deemed depreciation at a 25% diminishing-value rate for cars acquired on or after 10 May 2006, and deemed interest on the original purchase price at the statutory benchmark rate, which is 8.62% for the FBT year ending 31 March 2026.6Australian Taxation Office. Fringe Benefits Tax – Rates and Thresholds Multiply the total by the private-use percentage from the logbook, then subtract any employee contributions.5Australian Taxation Office. Taxable Value of a Car Fringe Benefit
If a logbook shows 80% business use, only 20% of total costs feed into the taxable value. The statutory formula, by contrast, always applies 20% to the base value regardless of how the car is used.
Logbook Requirements
Using the operating cost method means keeping a logbook for a continuous period of at least 12 weeks that is representative of typical travel across the FBT year. Each car needs its own logbook, and odometer readings must be recorded at the start of the FBT year on 1 April and again at the end on 31 March.7Australian Taxation Office. Car Fringe Benefits Tax Guide for Small Business
Every entry needs the date, start and finish odometer readings, distance, and a description of the trip’s purpose specific enough to show whether it was business or private. “Business” or “miscellaneous” won’t do. Something like “drove to client site at 42 Smith Street for quarterly review meeting” is what the ATO expects. A logbook stays valid for five years, but a new one is required sooner if the pattern of use changes materially. All FBT records must be kept for five years from the date they are prepared or the transaction is completed.8Australian Taxation Office. Fringe Benefits Tax – A Guide for Employers – Section 4.1
Without an adequate logbook, the ATO will treat the car as 100% privately used, wiping out any advantage the method offered. This is the single biggest mistake small businesses make on car FBT: choosing the method that could save the most money, then failing to keep the records that make it work.
Grossing Up and What the Tax Actually Costs
Once you have the taxable value, it must be grossed up before the 47% rate applies. Grossing up converts the tax-exclusive benefit into the pre-tax salary equivalent an employee would need to earn to buy the same benefit after income tax.
There are two rates. Type 1 (2.0802) applies when the employer is entitled to a GST credit on the benefit. Type 2 (1.8868) applies when no GST credit is available.6Australian Taxation Office. Fringe Benefits Tax – Rates and Thresholds For a car, the type depends on whether GST credits were claimed on the purchase price or lease payments.
Working the earlier example through: a $10,000 taxable value on a car where GST credits were claimed grosses up to $10,000 × 2.0802 = $20,802. FBT payable is $20,802 × 47% = $9,777. That is nearly the full taxable value again in tax, which is why method choice and record-keeping matter so much.
Ways to Reduce the Bill
Employee Contributions
An employee can reduce the taxable value by making after-tax contributions toward the cost of the car or its running expenses. These “recipient’s payments” come off the taxable value directly under either method.9Australian Taxation Office. Reducing Your FBT Liability Contribute enough to cover the whole taxable value and the FBT drops to zero. Many salary-packaging arrangements are built around this mechanic.
Electric Vehicle Exemption
Since 1 July 2022, private use of certain electric cars has been completely FBT-free. The exemption covers battery electric vehicles and hydrogen fuel cell electric vehicles that meet the standard FBT car definition and on which luxury car tax was never payable on any sale. For the 2025–26 financial year, that means the vehicle’s value must sit below the fuel-efficient LCT threshold of $91,387.10Australian Taxation Office. Electric Cars Exemption The exemption extends to associated running costs like registration, insurance, repairs, maintenance, and charging.
Plug-in hybrids no longer qualify. From 1 April 2025, PHEVs are not treated as zero or low emissions vehicles under FBT law.10Australian Taxation Office. Electric Cars Exemption Note also that although the benefit is exempt from FBT, it remains a reportable fringe benefit: you still calculate a notional taxable value and report it on the employee’s income statement if it exceeds the reporting threshold.
Work-Vehicle Exemption
Some vehicles that meet the “car” definition can still be exempt if private use stays tightly limited. Taxis, panel vans, utes designed to carry less than one tonne, and other vehicles not principally designed for passengers qualify, provided the employee’s private use is limited to home-to-work travel, travel incidental to work duties, and other private use that is minor, infrequent, and irregular.11Australian Taxation Office. Fringe Benefits Tax – A Guide for Employers
Dual-cab utes are a frequent source of confusion. Whether a dual-cab qualifies turns on its load capacity and primary design purpose. Getting this classification wrong can produce an unexpected FBT bill on a vehicle the employer assumed was exempt, so it’s worth checking the ATO’s dual-cab guidance before relying on the exemption.
Lodging and Paying
The FBT year runs 1 April to 31 March, separate from the income tax year. Employers must lodge the FBT return and pay by 21 May following the end of the FBT year. If a registered tax agent lodges the return electronically, the deadline generally extends to 25 June, provided the employer was on that agent’s client list by 21 May.12Australian Taxation Office. Lodging Your FBT Return and Paying
Employers who paid $3,000 or more in FBT in the previous year pay quarterly instalments through their Business Activity Statement rather than a single annual lump sum.13Australian Taxation Office. Fringe Benefits Tax Instalment Missing the lodgment deadline attracts penalties and interest, so businesses with car fringe benefits should slot FBT into the regular compliance calendar alongside BAS and income tax.
What the Employee Sees
If the total taxable value of fringe benefits provided to one employee exceeds $2,000 in an FBT year, the employer must report the grossed-up amount on that employee’s income statement. The minimum grossed-up value that triggers reporting is $3,773.6Australian Taxation Office. Fringe Benefits Tax – Rates and Thresholds
Reportable fringe benefits don’t create additional income tax for the employee, but they feed into several income tests, including eligibility for government benefits, the Medicare levy surcharge, and Higher Education Loan Program repayments. Employees receiving significant car fringe benefits should factor the reportable amount into their broader planning.
