Overhaul of motor vehicle FBT settings

The Taxation (Annual Rates for 2026–27, FBT Simplification, Foreign Investment Funds, and Remedial Measures) Bill introduced into the House late yesterday afternoon, unveils the biggest change to New Zealand’s Fringe Benefit Tax (FBT) settings in a generation. The long-awaited motor vehicle reforms were signalled in Budget 2026 and build on proposals consulted on in 2025.

The proposals aim to reduce the uncertainty and significant compliance costs associated with the current FBT rules. They would also provide greater clarity on the FBT treatment of work-related vehicles, including double-cab utes and vans, where the application of the existing exemption has not always been straightforward. Once fully implemented we expect the reforms to reduce compliance costs for many employers, but not necessarily their FBT liability.

The proposals are intended to apply from 1 April 2027. However, with an election approaching some uncertainty remains around the final form of the rules. As a result, employers may need to begin preparing for implementation before there is complete certainty about the detail of the new regime.

So, what is changing?

At its core, the proposed reforms would replace the current day-counting and existing workplace vehicle exemptions with a category-based framework built around vehicle use permissions.

Under existing laws, FBT is levied based on the “availability for use”, requiring employers to track the days a vehicle is available for private use and apply a range of exemptions. Under the new approach, vehicles would instead be allocated to one of six vehicle-use categories, each with a fixed inclusion rate applied to determine the taxable value of the benefit.

In broad terms, the categories seek to differentiate vehicles based on what private use the employer permits:

Category	Description	Inclusion rate*
Full private use	Vehicles provided primarily as an employment benefit, with unrestricted private use.	100%
Partial private use	Vehicles used mainly for business purposes but also available for private use on non-working days. Branded vehicles only.	35%
Farm vehicles	Certain farm vehicles when used by shareholder-employees of closely held farming companies or trusts. No branding required.	35%
Commuting vehicle: single worksite	Vehicles used to travel between home and a single workplace. Branded vehicles only.	20%
Commuting vehicle: multiple worksites	Genuine tool-of-trade vehicles used by employees who travel between multiple worksites, such as tradespeople, field technicians, community nurses and infrastructure workers. Branded vehicles only.	0%
Business use only pool vehicles	Vehicles not available for private use. No branding requirement.	0%

* Subject to the legislation being enacted in its current form.

The proposed framework places greater emphasis on an employer's intended use of a vehicle than on tracking its day-to-day use. When determining the correct category, the employer is asked to consider the “expected use” of the vehicle when it is first provided, supported by evidence such as workplace policies and employment agreements. This means that limited, occasional private use may not affect a vehicle’s classification when it is unusual, short in duration or ad hoc. However, this does not mean employers can disregard clear and material changes in permissions or expected usage. The law still requires employers to take reasonable care when classifying vehicles and maintain sufficient records to support the categories selected.

Note that if no category is selected, category 1 would apply by default.

Other changes of note

In addition to the changes in vehicle classification, the Bill also proposes to:

Introducing different rates for standard vehicles, hybrids and electric vehicles.

Vehicle type	Cost method (annual)	Tax book value (Investment Boost claimed)	Tax book value (Investment Boost not claimed)
Standard petrol/diesel	20.0% (No change)	41.4% (No change)	36% (No change)
Hybrid	▼ 19.6%	▼ 40.52%	▼ 34.12%
Electric	▼ 17.0%	▼ 35.00%	▼ 29.76%

The proposals retain the tax book value method but separate rates apply depending on whether Investment Boost has been claimed.

Increasing the gross laden weight threshold from 3,500kg to 6,000kg reflects the increasing weight of modern vehicles, in particular electric vehicles, and may result in additional vehicles falling within the FBT motor vehicle rules (for example, larger vehicles, specialist vehicles and campervans)

The proposals provide a new definition for emergency vehicles which includes ambulances, police cars and fire engines amongst others.

Our views

Overall, the proposals are a welcome step towards a simpler and more practical motor vehicle FBT regime. In some cases, the compliance obligations imposed by the current rules can be disproportionate to the amount of tax ultimately collected.

However, this is more than a technical tax tweak. The changes will fundamentally alter how FBT on employer-provided vehicles is managed, affecting fleet settings, employment policies, tax processes and documentation, as well as the amount of overall FBT payable. While the reforms are intended to reduce ongoing compliance effort, implementing the new framework is likely to require a significant investment of time and resources. Employers may therefore need to start planning, well before the proposed commencement date.

While the new approach removes the need for day-counting and logbooks, it places greater emphasis on getting the classification, policy settings and supporting records right. In particular, the distinction between the single-worksite and multiple-worksite categories is likely to receive close attention. Given the difference between the 20% and 0% inclusion rates, employers will need clear guidance, robust policies and appropriate records to support their classifications and effectively differentiate commuting vehicles from genuine tool-of-trade vehicles.

What should employers do now?

Given the proposed commencement date and the scale of the changes, employers should not wait for enactment to begin implementation preparations. Our checklist sets out the practical steps to get ready, including: steps to identify impacted vehicles, confirm what private use is permitted, test the likely category for each arrangement and model the financial impact. Particular attention should be paid to vehicles currently treated as work-related vehicles, vehicles assigned to individual employees vs. pool vehicles , and to vehicle branding approaches.

We note that the new branding requirements apply prospectively from the date of introduction of this Bill (10 September 2026), meaning compliance teams should ensure branding requirements are considered for all new vehicles unless an exemption to the requirement is secured.

Just as importantly, documented policies and day-to-day practices need to align. Vehicle policies, employment agreements and private use restriction letters should clearly state the permitted use, and the people responsible for fleet management and FBT returns need adequate training and support to understand and implement the new rules.

What happens next?

The new rules are proposed to apply from 1 April 2027. However, the outcome of this year's general election adds uncertainty to the legislative process, as the next Government will need to decide whether to reinstate the Bill and whether the reforms should proceed in their current form.

Assuming post-election arrangements are finalised within a reasonable timeframe, greater clarity on the future of the Bill may emerge before the end of the year. The Select Committee process should wrap up by February 2027, providing employers with greater certainty but little time in which to act before the 1 April go-live.

While the legislative process still has some way to run, employers have an opportunity to begin assessing how the proposed changes may affect their vehicle fleet, policies and compliance processes.
