FBT on pool cars: statutory vs operating cost, and the EV exemption

By The IntelliTrac team · 28 May 2026 · Compliance & tax

How to value car fringe benefits on pool and company vehicles in Australia — the statutory formula, the operating cost method, and when the electric car FBT exemption applies.

Pool cars are one of the most common — and most misunderstood — sources of fringe benefits tax. The moment a vehicle is available for an employee's private use, a car fringe benefit can arise, even on the nights and weekends it sits in a depot. The good news is that Australian rules give you two ways to value that benefit, and choosing the right one can change the bill substantially.

Two methods, two very different answers

Every car fringe benefit can be valued with either the statutory formula method or the operating cost method. You can use whichever gives the lower taxable value each FBT year, provided your records support it.

The statutory formula method

This is the simpler path. The taxable value is the car's base value multiplied by a flat statutory rate of 20%, pro-rated for the days the car was available for private use, less any after-tax contributions the employee makes. The base value is the GST-inclusive cost plus delivery and non-business accessories — it excludes registration and stamp duty. After the car has been held for four full FBT years, the base value drops by one third.

The operating cost method

This method values the benefit on actual running costs — fuel, servicing, insurance, registration — plus deemed depreciation and interest for owned vehicles, multiplied by the private-use percentage. It usually wins when business use is high, but it only works if you have a valid logbook: twelve continuous weeks, valid for five years, backed by odometer records.

The method is not the hard part. The hard part is proving the days available, the private-use percentage and the contributions—and that is a data problem, not a tax problem.

The electric car exemption

Eligible battery-electric and hydrogen fuel-cell cars first held and used on or after 1 July 2022, priced under the luxury car tax fuel-efficient threshold, are exempt from FBT. The benefit is still reportable, so you still need its notional value — but the FBT itself is nil. Plug-in hybrids lost eligibility from 1 April 2025 unless they were already covered by a binding commitment.

Where the data comes from

Whichever method you choose, you need the same basic information. It should come from normal fleet use, not a spreadsheet rebuilt at year end:

• Booking and trip history showing who had the car and when it was genuinely unavailable for private use.
• Logbook and odometer data to substantiate the business-use percentage under the operating cost method.
• Garaging and after-hours use, so home-garaged cars are classified correctly.
• Employee contributions, captured against the right vehicle and period.
