Fringe benefit tax applies to a work vehicle when it is available for an employee’s private use, whether or not they actually use it that way. The employer pays it, not the employee. Some vehicles escape it under the work-related vehicle exemption, but that exemption is narrower than most businesses assume, and signwriting alone does not earn it.
The rules are also about to change. A Bill before Parliament would replace the current availability test from 1 April 2027. Both the current position and what is coming are set out below.
What FBT is and who pays it
Fringe benefit tax is a tax on non-cash benefits an employer gives an employee. If you paid someone an extra $10,000 in salary, PAYE would catch it. Give them the use of a $60,000 vehicle instead and FBT is what stops that from being a way around the tax system.
The employer pays FBT. Not the employee. It is an employer cost, returned quarterly, annually or on an income-year basis depending on how you file.
Vehicles are far and away the most common trigger. A ute parked at a staff member’s house, a company car a director drives at weekends, a van someone takes home so they can start early. Shareholder-employees of small companies are caught just as readily as staff, which is where a lot of owner-operators are surprised.
For the 2026 year the FBT rates are a single rate of 63.93% applied to all benefits, or an alternate rate of 49.25% available in quarters one to three for quarterly filers, with a square-up in quarter four. Those are high numbers, which is why getting the vehicle question right matters more than its size suggests.
The test that decides it: available, not used
This is the single most misunderstood point in the whole regime, so it is worth stating bluntly.
FBT is payable for every day a vehicle is available for an employee’s private use. Whether they actually drive it privately is beside the point.
A ute that sits in a staff member’s driveway all weekend and never moves is available for private use on Saturday and Sunday. Unless something removes that availability, those are FBT days.
Travel between home and work counts as private use. That catches people out constantly, because it feels like work travel. It generally is not, with narrow exceptions.
There are days FBT does not apply, including days the vehicle is away for repairs, days it is used for emergency call-outs that meet the criteria, and days an employee is travelling on business and away overnight. Each has conditions, and each has to be recorded to be claimed.
The practical consequence: if you want to stop the clock, you have to actually remove availability and be able to show you did. An understanding that someone will not use the ute privately is not worth anything if it is only an understanding.
The work-related vehicle exemption
This is the exemption people mean when they say “it’s a work ute, so there’s no FBT.” It is real, but every condition has to be met. All of them, not most.
- The vehicle is drawn or propelled by mechanical power, which includes a trailer.
- Its gross laden weight is 3,500 kg or less.
- It is mainly designed to carry goods, or goods and passengers equally. A vehicle mainly designed to carry passengers does not qualify, however it is used.
- The business’s regularly used identification is permanently and prominently displayed on the exterior. Magnetic signs and removable decals do not count.
- The employee has been given written notice that the vehicle is not available for private use, and that notice sets out the actual days.
The exceptions inside condition 5 are travel between home and work where that travel is necessary and a condition of employment, and travel incidental to business travel.
Why businesses get this wrong
A signwritten double-cab ute is not automatically exempt. Condition 3 asks what the vehicle is mainly designed to carry. Some double cabs are built as goods vehicles and some are built as passenger vehicles with a tray, and the classification follows the design, not the badge or the use.
Magnetic signs fail condition 4. The requirement is permanent.
The written notice is a document, not a conversation. No notice, no exemption, no matter how the vehicle is actually used.
The exemption is day-by-day. Let an employee take an exempt vehicle away for the weekend and those days are back in the net.
If you are relying on this exemption across a fleet, it is worth having someone check the classification of each vehicle and confirm the notices exist. The cost of being wrong compounds quietly across quarters.
How FBT on a vehicle is calculated
You choose one of two valuation methods, and you stay with it for that vehicle.
Cost price method. A percentage of what the vehicle cost. Simple, and it never reduces, so an old vehicle keeps attracting the same FBT as it did when new.
Tax book value method. A percentage of the vehicle’s depreciated value, subject to a minimum. The charge falls as the vehicle ages, but there is a floor: the minimum tax book value is $8,333, or $7,317 where Investment Boost has been claimed.
The percentages
| Method | Return period | GST-inclusive | GST-exclusive |
|---|---|---|---|
| Cost price | Quarterly | 5% | 5.75% |
| Cost price | Annual or income year | 20% | 23% |
| Tax book value | Quarterly | 9% | 10.35% |
| Tax book value | Annual or income year | 36% | 41.40% |
| Tax book value, Investment Boost claimed | Quarterly | 10.35% | 11.90% |
| Tax book value, Investment Boost claimed | Annual or income year | 41.40% | 47.61% |
Working one out
For a quarterly filer the taxable value is:
\text{taxable value} = \text{cost price} \times 5\% \times \frac{\text{days available for private use}}{90}Take a $60,000 (GST-inclusive) ute available to an employee for all 90 days of a quarter, with no exemption:
- Taxable value: $60,000 × 5% × 90/90 = $3,000
- FBT at the single rate of 63.93%: $1,918 for the quarter
- Roughly $7,670 a year
On a vehicle that cost $60,000, that is close to 13% of the purchase price every year, indefinitely, under the cost price method. It is a real line item and it belongs in the numbers before you buy, not after.
Which method is better depends on the vehicle. Cost price is simpler and often cheaper for an expensive vehicle you will replace quickly. Tax book value rewards holding a vehicle a long time, until it hits the floor.
Reducing the liability, legitimately
Four things actually work.
Remove availability in writing. A restriction letter telling the employee the vehicle is not available for private use, specifying the days, is the mechanism the rules provide. It has to be genuine and it has to be enforced. A letter that everyone ignores is worse than no letter, because it documents that you knew.
Keep the vehicle on site. If it stays at the depot overnight and keys are held there, private use is not available. This is the cleanest answer and the least popular one.
Pick the right vehicle at the point of purchase. The work-related vehicle exemption turns on the design of the vehicle and permanent signwriting. Both are decided when you buy. A business that knows the rules before it chooses can often end up with a vehicle that does the same job and attracts no FBT.
Check your valuation method. Cost price and tax book value produce quite different numbers over a vehicle’s life. For a vehicle you will hold a long time, tax book value is usually cheaper.
What does not work: an informal agreement, hoping nobody asks, or assuming a ute is exempt because it is a ute.
What is changing from 1 April 2027
The vehicle FBT rules are being rewritten. The Taxation (Annual Rates for 2026–27, FBT Simplification, Foreign Investment Funds, and Remedial Measures) Bill was introduced on 10 September 2026 and is not yet enacted. As drafted, it would apply from 1 April 2027.
The headline changes:
- The availability test goes. Instead of counting days a vehicle was available, employers would classify each vehicle into a category when it is allocated to an employee, based on expected use. Reclassification would only be needed if expected use materially changes.
- The work-related vehicle exemption is repealed, replaced by a specific exemption for emergency service vehicles.
- An inclusion rate replaces day counting. Each category carries a percentage of the benefit that is subject to FBT.
| Category | Description | Proposed inclusion rate |
|---|---|---|
| 1 | Mainly private use | 100% |
| 2 | Mainly business use, partial private use | 35% |
| 3 | Mainly business use on farmland | 35% |
| 4 | Mainly business use, minor private use (commuting to the same worksite) | 20% |
| 5 | Business use only, commuting across multiple worksites or limited-duration projects | 0% |
| 6 | Pool vehicles with no private use | 0% |
Valuation percentages would also change and would vary by fuel type, with lower rates for hybrid and electric vehicles.
What to do about it now. Nothing changes for the 2026–27 year. But if you are buying a vehicle on a three or five year term, it will spend most of its life under the new rules. A vehicle bought today purely to fit the work-related vehicle exemption may be sitting in a category with a real inclusion rate by 2027. That is worth factoring into the decision, and worth a conversation with your accountant before you commit.
Five mistakes that cost real money
- Assuming a signwritten ute is exempt. The exemption has five conditions and the design classification is the one most often failed.
- No written restriction notice. Businesses that genuinely keep vehicles off private use still pay FBT because they never documented it.
- Treating home-to-work travel as business travel. It is generally private use.
- Forgetting shareholder-employees. A one-person company with a vehicle is squarely in scope.
- Leaving FBT out of the purchase decision. On a $60,000 vehicle under the cost price method it can run close to $7,700 a year. Over a five-year hold that is more than half the vehicle’s price again.
Common questions
Who pays fringe benefit tax in New Zealand?
The employer. FBT is an employer cost, not a deduction from the employee’s pay. For a small company providing a vehicle to a shareholder-employee, the company pays it.
When does FBT apply to a work vehicle?
On every day the vehicle is available for an employee’s private use, whether or not it is actually used privately. Travel between home and work generally counts as private use.
How do I calculate FBT on a company car?
For a quarterly filer, multiply the vehicle’s GST-inclusive cost price by 5%, then by the days available for private use divided by 90. That gives the taxable value. Apply the FBT rate, 63.93% at the single rate, to get the tax. The tax book value method uses 9% a quarter instead, subject to a minimum tax book value of $8,333.
Is a signwritten ute exempt from FBT?
Not automatically. The work-related vehicle exemption requires a gross laden weight of 3,500 kg or less, a design mainly for carrying goods, permanent and prominent business signwriting, and written notice to the employee that the vehicle is not available for private use. All conditions must be met, and the exemption applies day by day.
Do magnetic signs count for the work-related vehicle exemption?
No. The identification has to be permanently and prominently displayed. Magnetic or otherwise removable signage does not satisfy the requirement.
Does FBT apply to a sole trader’s vehicle?
FBT applies to benefits provided to employees, so a sole trader with no employees is generally outside it. The private-use portion is dealt with through income tax and GST apportionment instead. A company providing a vehicle to a shareholder-employee is a different situation and is in scope.
Are the FBT rules for vehicles changing?
Yes, as proposed. A Bill introduced on 10 September 2026 would replace the availability test with a category-based system from 1 April 2027 and repeal the work-related vehicle exemption. It has not been enacted, so the current rules continue to apply until then.
Count it before you buy, not after
FBT is the cost most businesses discover a quarter too late. It is not decided by how you use the vehicle so much as by what you bought and how you set it up, and both of those are settled on the day you sign.
When we are arranging finance on a ute, van or company car, the FBT position is part of the conversation. Not because we give tax advice, but because a vehicle that creates $7,000 a year of FBT and one that does not can have identical finance repayments, and the total cost of ownership is the number that matters.

Current as at November 2026. The motor vehicle FBT rules are subject to a Bill before Parliament with a proposed start date of 1 April 2027. This article will be updated when the legislation is enacted.
