If you run a small business in New Zealand and hand an employee the keys to a company vehicle, you know the Friday-afternoon ritual: chasing logbooks, counting the days the ute was "available for private use," and arguing with yourself about whether last Saturday counts. Inland Revenue is proposing to end all of that. Under the Budget 2026 fringe benefit tax (FBT) overhaul, you would stop counting days entirely and instead pick the category that best describes each vehicle's private use, then pay FBT at that category's rate. No logbook. No day-count. Just a box to tick.
The proposal is exactly what it sounds like: "close enough is good enough." But the categories have sharp edges — branding rules, a disappearing exemption, and slightly higher valuation rates — that can move your FBT bill up or down. Here is what the changes would mean for your fleet, and what to do before they take effect for benefits provided after 1 April 2027.
Note the status: this is a Budget 2026 proposal working its way through Parliament, and details may change before enactment. Treat everything below as the plan as published, and confirm the final rules with your accountant before you restructure anything.
How FBT on Vehicles Works Today (and Why Everyone Hates It)
Right now, FBT on a motor vehicle is driven by availability, not by actual use. If a vehicle is available for an employee's private use on a given day, that day generally counts toward your FBT calculation for the quarter — whether the employee drove to the beach or left the ute parked in the driveway. You prove the split with records and logbooks, and the compliance burden lands hardest on small employers who have neither a fleet manager nor a payroll team.
There are carve-outs, but they come with their own paperwork. The work-related vehicle exemption, for example, spares qualifying vehicles from FBT, but only if the vehicle meets design conditions (no rear doors or rear seats in some configurations, permanent signage in others) and you hold the right records. Get one condition wrong and the exemption evaporates. Inland Revenue's own consultation material acknowledges that FBT compliance costs are a long-running sore point for employers, and vehicles are the worst of it.
The New System: Six Categories, One Choice Per Vehicle
The proposal replaces day-counting with a category approach. When you provide a vehicle to an employee, you select a category upfront based on the private use you expect, and you only revisit the choice if that expected use changes materially. Each category carries an inclusion rate — the percentage of the vehicle's taxable value that ends up subject to FBT.
| Category | In a nutshell | Inclusion rate | Branding required? |
|---|---|---|---|
| 1 – full private use | Perk vehicles, mainly for private use; part of the remuneration package | 100% | No |
| 2 – partial private use | Mainly business; private use allowed on rostered days off, public holidays, statutory leave, plus commuting | 35% | Yes |
| 2b – limited private use (farm vehicles) | Supports farming operations on farmland; private use allowed when not working; closely held farming company, shareholder-employee driver | 35% | No |
| 3 – minor private use | Only private use is commuting to the same worksite by the same employee | 20% | Yes |
| 4 – minor private use (multi-site) | Only private use is home-to-work commuting where work spans multiple worksites | 0% | Yes |
| 4b – no private use (pool car) | Exclusively business use, not allocated to one employee | 0% | No |
Two design points matter for every category. First, incidental private use — infrequent, ad hoc use that is not really remuneration, such as an employee borrowing the work van for one weekend to move house — would neither change the vehicle's category nor attract FBT. Second, the existing work-related vehicle exemption would be repealed, because the categories are meant to absorb the vehicles it currently covers. In exchange, certain emergency vehicles would get a new full exemption from the FBT regime.
What Each Category Means in Practice
Category 1: the perk car stays fully taxed
If the vehicle is essentially part of someone's pay — a car provided mainly for private use — nothing about the outcome changes much. The inclusion rate is 100%, and branding is irrelevant. If you provide senior staff with cars they drive as their own, budget for the same FBT treatment as today.
Category 2: the classic branded ute, at 35%
This is the category most trades and services businesses will live in. Picture a maintenance company whose technicians drive branded utes during the week and are allowed to use them on weekends and public holidays. Under the proposal that vehicle sits in Category 2 with a 35% inclusion rate — and nobody fills in a logbook.
Inland Revenue's published example makes the comparison concrete: under today's rules, a vehicle available for private use each Friday, Saturday, and Sunday racks up about 36 taxable days in a typical quarter, roughly a 40% inclusion rate. Under Category 2 the same pattern of use would attract 35%, with the logbook compliance cost gone. That is the reform's promise in one number: just under today's bill, with far less paperwork.
Watch the conditions, though. The vehicle must be branded, and private use beyond the permitted windows — rostered days off, public holidays, statutory leave, commuting, plus genuinely incidental use — risks pushing the vehicle out of the category. Commentators have already flagged that any regular private use outside the strict parameters could land a vehicle in Category 1 at 100%, so written vehicle-use policies will matter more than ever.
Category 2b: farm vehicles get their own lane
Farm utes and trucks used to support farming operations on farmland, owned by a closely held company in the farming business and driven by a shareholder-employee, get a dedicated 35% category with no branding requirement. If that describes your setup, you no longer need to defend the work-related vehicle exemption's design tests — but you do need to confirm the ownership and driver conditions are met.
Category 3: same person, same worksite, 20%
If the only private use you permit is one employee commuting to one fixed worksite, the vehicle falls into Category 3 at 20% — provided it is branded and others may still use it for business during the day. This suits office or depot-based staff with a take-home vehicle. The branding requirement is the tripwire: an unbranded vehicle that otherwise fits here does not qualify.
Category 4: multi-site workers could pay zero
This is the standout for construction, maintenance, and field-services businesses. If the only private use is commuting, and the employee's work inherently spans multiple worksites, the inclusion rate is 0% — no FBT at all — as long as the vehicle is branded. A builder whose crew drives a signwritten ute from home to whichever site is active that week is the textbook case. Document the multi-site nature of the work, keep the branding on, and police the "commuting only" boundary.
Category 4b: genuine pool cars stay out
Vehicles used exclusively for business, not allocated to any single employee, sit outside FBT entirely at 0% with no branding requirement. If your pool car discipline is real — keys on the board, no take-homes — this category costs you nothing.
The Small Print That Could Move Your Bill
The categories are only half the story. The proposal also updates the valuation rates applied to a vehicle's cost price (or tax book value), and those move upward overall — partly reflecting higher running costs since the rates were last reviewed in 2009. The headline changes:
- Cost-price base: the standard rate rises from 20% annually to 22.8% (5% to 5.7% quarterly). New lower rates appear for hybrids (19.6% annually) and electric vehicles (17.0% annually).
- Tax book value option: the standard rate rises from 41.4% to 47.25% annually, again with lower hybrid (40.50%) and EV (35%) rates.
A few qualifications: the rates include a 12.5% discount for periods the vehicle is unavailable for private use (mechanical issues and the like), and the book-value rates assume Investment Boost has been claimed on the vehicle. Major shareholder-employees keep access to the alternative calculation under section CX 17 of the Income Tax Act 2007.
The practical upshot is that the reform's winners and losers depend on your fleet mix. A branded weekend-use ute taxed at 35% instead of roughly 40% likely pays less FBT even with the higher base rate. An unbranded vehicle that loses the old work-related vehicle exemption and lands in Category 1 could pay considerably more. And if you are choosing your next fleet vehicle, the new hybrid and EV rates are a genuine incentive worth modelling.
What to Do Before 1 April 2027
The changes would apply to benefits provided after 1 April 2027, which gives you two FBT years to prepare. Work through this checklist with your accountant:
- Inventory every vehicle and its real private use. For each car, ute, and van, write down who drives it, where it sleeps at night, and what private use is actually permitted. Be honest — the gap between the written policy and reality is where FBT risk lives.
- Assign each vehicle a provisional category. Map today's use patterns onto the six boxes. Flag any vehicle whose category is ambiguous or depends on a condition you do not currently meet (usually branding).
- Check your branding. Categories 2, 3, and 4 all require it. If a vehicle needs livery to qualify for 35%, 20%, or 0%, get quotes now rather than discovering the requirement in March 2027.
- Put vehicle-use agreements in writing. The categories turn on what private use is permitted, so a signed policy saying "commuting to the depot only" or "weekends and public holidays permitted" is your primary evidence. Update agreements that still reference logbooks and day-counts.
- Model the dollar impact, including the new rates. Run each vehicle under today's rules versus its likely category at the new valuation rates. Price the hybrid and EV options for your next replacement cycle while you are at it.
- Review shareholder-employee vehicles. If you use the section CX 17 alternative calculation, confirm with your adviser that it still beats the category outcome for each vehicle.
- Watch the Bill. The proposal may change in Parliament. Do not paint the fleet or rewrite every agreement until the legislation is final — but have the plan ready so you can move fast.
