Budget 2026 confirms the Government will simplify the fringe benefit tax rules that apply to private use of motor vehicles, a change aimed at reducing compliance costs for businesses that provide vehicles to staff.
The measure appears in the revenue section of the Budget delivered by Finance Minister Nicola Willis on Thursday, alongside changes to tax rules for charities and not-for-profits and a new prudential levy on banks and other financial institutions.
The Budget papers describe the change as simplifying FBT rules for private motor vehicle use to reduce compliance costs. Detailed design of the new rules is expected to follow through Inland Revenue’s tax policy process and a future tax bill.
The change follows a review of the FBT regime that Inland Revenue began in 2025. An officials’ issues paper released in April 2025 sought feedback on options for change, with submissions closing in May 2025. A major focus of that review is how FBT applies to motor vehicles provided by an employer.
Inland Revenue has identified the current motor vehicle rules as a significant source of compliance effort. Under the existing regime, employers calculate the taxable value of a vehicle benefit partly by counting the days a vehicle is available for private use, and the rules carve out separate treatment for work-related vehicles. Officials have signalled that simplifying how the benefit is measured is central to lowering the compliance burden.
The change is relevant to dealers selling into the fleet and business market, and to operators running company vehicles, where FBT treatment is a factor in total cost of ownership calculations and vehicle policy decisions.
Until the supporting documents are released, the practical effect on how vehicle benefits are valued, and any change to the treatment of work-related vehicles, remains to be confirmed.
The Budget measure is distinct from an already-legislated change taking effect from 1 April 2026, under which the 20 percent Investment Boost deduction is ignored when calculating FBT on motor vehicles. That earlier change sets a minimum tax book value for affected vehicles and was confirmed ahead of this Budge
