Fringe Benefit Tax (FBT) Rules for Company Cars or Work Vehicles in Australia

FBT trips up more Australian employers than almost any other tax obligation. The rules around company cars are detailed, the record-keeping requirements are specific, and the cost of getting it wrong, in both underpaid tax and penalties, adds up quickly. Fringe Benefits Tax is paid by the employer at a flat rate of 47%, the highest marginal rate, on the taxable value of non-cash benefits provided to employees. For any business providing vehicles to staff, understanding how FBT applies, and where it doesn’t, is a basic compliance requirement that also offers real opportunities to reduce the tax bill with the right approach.

The FBT year in Australia runs from 1 April to 31 March, which means it sits outside the standard income tax year. FBT returns are due by 21 May, giving employers roughly seven weeks after the FBT year ends to calculate their liability and lodge. Missing that deadline attracts penalties and interest, so building the FBT return into your annual compliance calendar well before the due date matters.

 

What FBT on a Car Actually Means

FBT on a company car is triggered when an employer makes the vehicle available for an employee’s private use. The key word is “available.” The ATO does not require proof that the car was actually driven privately. If it’s parked at the employee’s home overnight or on weekends, the ATO treats that availability as private use, regardless of whether it was actually driven. Businesses that think leaving a car with an employee avoids FBT unless they can prove private use are mistaken, and that misconception creates significant exposure.

FBT is separate from income tax. It’s the employer’s liability, not the employee’s, though the value of certain fringe benefits must be reported on the employee’s income statement as a Reportable Fringe Benefits Amount (RFBA). That reporting affects the employee’s adjusted taxable income, which flows through to Medicare Levy Surcharge calculations, certain government benefits, and other income tests.

The Bentleys guide to FBT for employers covers the full range of fringe benefit types and calculation methods in detail, including cars, salary sacrifice arrangements, and entertainment.

 

The Two Methods for Calculating Car FBT

Employers can choose between two methods for calculating the taxable value of a car fringe benefit, and selecting the right one for each vehicle can meaningfully reduce the FBT bill.

The statutory formula method is the simpler of the two. The taxable value is calculated as 20% of the car’s base value (essentially the purchase price including GST and luxury car tax, but excluding registration and stamp duty), multiplied by the number of days the car was available for private use during the FBT year, divided by 365. The 20% statutory fraction applies regardless of how much the car is actually used privately, which means this method can produce a high taxable value for cars that are predominantly used for business. Employee after-tax contributions to the running costs of the car reduce the taxable value calculated under the statutory formula.

The operating cost method calculates FBT based on the actual costs of running the vehicle, including fuel, registration, insurance, repairs, and lease payments, then applies the private use percentage to determine the taxable value. A car used 80% for business and 20% privately produces a taxable value based on 20% of total operating costs, which is significantly lower than the statutory formula would produce for the same car. The operating cost method requires a valid logbook and accurate business use records, but for vehicles driven mainly for work, it almost always produces a better result.

Choosing the method that results in the lower taxable value each year is permitted, and it’s worth running both calculations before lodgement.

 

Logbooks and Business Use Records

The logbook is the cornerstone of FBT record-keeping for car fringe benefits, and failing to maintain one effectively forces employers into the statutory formula method regardless of actual business use. A valid logbook must cover at least 12 consecutive weeks of vehicle use and record every trip taken during that period, including the date, purpose, destination, and kilometres driven. The logbook establishes the business use percentage, which then applies for up to five years unless there is a significant change in how the car is used.

Odometer readings at the start and end of the FBT year are also required, as they form the basis for total distance calculations. Digital logbook apps are acceptable, provided they capture all the required information. The ATO does not require a particular format, but the records must be consistent and complete enough to support the business use percentage claimed.

Employers should also keep records of any employee contributions to vehicle costs. Payments for fuel, servicing, or insurance made by the employee from after-tax income directly reduce the taxable value of the car fringe benefit and lower the FBT payable.

 

FBT Exemptions for Utes and Commercial Vehicles

The dual cab ute FBT exemption is widely misunderstood, and acting on a misconception here is one of the most common and costly mistakes in fleet management for Australian trade and construction businesses. The Bentleys November 2025 client alert on FBT and work utes sets out the position clearly: dual cab utes are not automatically exempt from FBT.

For a vehicle to qualify as an exempt work-related vehicle, it must first be a vehicle designed to carry a load of one tonne or more, or more than eight passengers, or alternatively it must not be designed principally for private use. Most dual cab utes on Australian roads satisfy that first condition. The second condition is where businesses get caught: any private use must be minor, infrequent, and irregular. All three elements must be satisfied simultaneously. Home-to-work travel is permitted, and incidental private use while on work duties is acceptable. Regular use of the vehicle on weekends, for school runs, or for recreational travel disqualifies the exemption, even if each individual trip is short.

Employers do not need to maintain a formal logbook for exempt vehicles, but they do need records demonstrating that private use genuinely meets the ATO’s criteria. Regular odometer checks comparing expected work travel against actual readings is the standard approach.

 

Electric Vehicles and the FBT Exemption

Battery electric vehicles and hydrogen fuel-cell vehicles below the luxury car tax threshold (currently around $91,387 GST-inclusive) are exempt from FBT when provided through novated leases or employer salary sacrifice arrangements. The exemption represents a genuine incentive for businesses and employees considering fleet electrification, and for employees entering novated lease arrangements, it can significantly reduce the net cost of the vehicle.

Plug-in hybrid vehicles lost eligibility for the FBT exemption from April 2025. Any plug-in hybrid vehicles already covered by a financially binding commitment entered into before 1 April 2025 may continue to access the exemption until the commitment ends, but no new arrangements involving plug-in hybrids attract the exemption from that date. The broader electric vehicle FBT exemption is currently under government review, with a statutory report due by mid-2027, and changes to the exemption’s scope remain possible. Businesses structuring fleet decisions around this concession should monitor developments closely.

 

Salary Sacrifice, Novated Leases, and the FBT Interaction

Salary sacrifice car arrangements allow employees to exchange pre-tax salary for a company car or novated lease, reducing their taxable income. However, the employer’s FBT liability does not simply disappear in these arrangements. The value of the car benefit is still subject to FBT unless an exemption applies, such as the electric vehicle exemption discussed above.

In a novated lease, the lease obligations transfer to the employer as part of the salary sacrifice arrangement. The employer makes lease payments, deducts them from the employee’s pre-tax salary, and takes on the FBT liability for any private use of the vehicle. Post-tax employee contributions can be structured to eliminate or reduce the FBT liability, which is why novated lease arrangements are typically structured with a combination of pre-tax and post-tax components. Getting the structure right requires careful calculation before the arrangement is put in place, because correcting a poorly structured novated lease mid-term is administratively difficult.

 

The Luxury Car Limit and Base Value Calculation

For FBT purposes, the base value of a car is the purchase price including GST and luxury car tax, less registration and stamp duty costs. Where a car’s value exceeds the ATO’s luxury car tax threshold (currently $80,567 for fuel-efficient vehicles and $69,674 for other vehicles in 2024-25), the excess forms part of the car cost used in FBT calculations, but only the portion up to the car limit applies for the purpose of calculating deemed depreciation under the statutory formula.

The base value reduces by a third at the start of the fourth year the car is held. This deemed depreciation reduces the taxable value under the statutory formula for older vehicles, which is a legitimate way to lower FBT costs on established fleet cars without any change to usage patterns.

 

FBT Reporting Obligations and RFBA

Employers must lodge an FBT return each year by 21 May and pay any FBT owing at the same time. Where total FBT liability for the year is nil, a return still needs to be lodged if the employer had a liability in the previous year, unless the ATO confirms otherwise.

Employees whose car fringe benefits produce a grossed-up taxable value of more than $2,000 for the FBT year must have the RFBA reported on their income statement. The RFBA is not additional taxable income for the employee, but it is included in their adjusted taxable income for a range of purposes including Medicare Levy Surcharge, certain Centrelink benefits, and private health insurance rebate calculations. Employers who miscalculate or omit the RFBA expose employees to unexpected outcomes in their personal tax returns, which creates problems that flow back to the employer.

Working with Bentleys’ tax advisory team ensures FBT returns are calculated correctly across all vehicle types, salary sacrifice arrangements, and employee contribution structures before lodgement.

 

Managing FBT Across a Vehicle Fleet

For businesses operating multiple vehicles, consistency in record-keeping and calculation methodology is the foundation of manageable FBT compliance. Each vehicle in the fleet needs its own logbook, odometer records, and contribution documentation. Businesses that treat fleet FBT as a single annual estimate rather than a vehicle-by-vehicle calculation often find, when the ATO looks closely, that the liability is materially different from what was lodged.

Fleet managers should review the calculation method for each vehicle at the start of each FBT year. A car’s usage pattern can change as employees’ roles change, and the method that produced the lowest taxable value in one year may not be optimal in the next. The Australian Taxation Office publishes annual updates to FBT rates, thresholds, and benchmark interest rates that affect calculations across the fleet.

Getting professional advice before lodgement, rather than after an ATO review has commenced, is the most cost-effective way to manage fleet FBT. The Bentleys EOFY tax planning resource is updated annually and covers FBT alongside the full range of year-end tax considerations for Australian businesses.

 

Your Next Step

FBT on company cars and work vehicles is one of the most active areas of ATO compliance activity. With the ATO increasing its focus on fringe benefits that have historically had lower audit rates, businesses that have been managing FBT on rough estimates rather than proper records face real exposure. Reviewing your vehicle fleet against the logbook requirements, double-checking exempt vehicle claims, and confirming your calculation methodology ahead of the next FBT year-end are practical steps you can take now.

Speak with a Bentleys chartered accountant to review your FBT position, confirm whether your current records support the exemptions you’re claiming, and model the tax impact of any planned changes to your fleet or vehicle arrangements.
