Is a double cab ute exempt from FBT in NZ?

Not automatically. Inland Revenue has confirmed that a double cab ute can qualify for the Work-Related Vehicle (WRV) FBT exemption, but only if all four conditions are met: the vehicle must be designed equally for carrying people and goods (not exclusively for people), it must have permanent and prominent business identification on the exterior, the employer must issue a written letter of restriction prohibiting private use beyond home-to-work travel, and the employer must conduct quarterly compliance checks. The widespread belief that all utes are automatically FBT-exempt is incorrect and one of the most common FBT errors.

What are the four requirements for the WRV FBT exemption?

The four requirements are: (1) the vehicle must not be designed exclusively or mainly to carry people (excludes most cars; double cab utes qualify because they are dual purpose); (2) it must have permanent and prominently displayed business identification on the exterior (magnetic signs do not count); (3) the employer must provide a written letter of restriction stating the vehicle is not available for private use except home-to-work travel and incidental business travel; (4) the employer must conduct quarterly checks to ensure the restriction is being followed (logbooks, petrol receipts, GPS data).

Does a magnetic company sign count for the WRV exemption?

No. The business identification must be permanent and prominently displayed. Magnetic signs, removable decals, or signs that can be taken off when the vehicle is used privately do not satisfy the WRV exemption requirements. The signage must be permanently affixed (vinyl wraps, painted-on logos, or permanent decals) and must be on the vehicle exterior at all times.

What counts as private use for the WRV exemption?

The WRV exemption allows two types of travel: home-to-work commuting and travel that is incidental to business use (such as stopping at the supermarket on the way home from a job site). Anything else - school runs, weekend errands, taking the family out, vacation use, holiday trips - breaks the exemption for those days. The exemption applies on a daily basis, so you can pay FBT on Saturdays and Sundays only if the vehicle is allowed for private use on weekends, while keeping the exemption for weekdays.

What if the vehicle weighs more than 3,500 kg?

Vehicles with a gross laden weight (GLW) over 3,500 kg are NOT covered by the standard motor vehicle FBT rules at all. They fall outside the FBT motor vehicle definition and are treated as unclassified benefits if provided for private use. This means a private-use heavy truck would be valued differently for FBT (typically based on the actual cost of the private use rather than availability), and may be subject to the de minimis exemption.

Work-Related Vehicle FBT Exemption Checker NZ

Despite what your mates at the building site might tell you, double cab utes are NOT automatically exempt from FBT. The Work-Related Vehicle (WRV) exemption requires four specific conditions to be met every day, and IRD has confirmed it is targeting the misclassification of utes as a compliance focus. This checker walks through all four requirements (vehicle design, signwriting, written restriction, quarterly checks) and tells you whether your vehicle qualifies, plus what to fix if it doesn't.

Updated April 2026 Tests the WRV exemption per section CX 38 of the Income Tax Act 2007 and IRD's Interpretation Statement IS 17/07.

Test 1: Vehicle type and design

What type of vehicle are you checking?

Test 2: Vehicle weight

Gross Laden Weight (GLW)

Check the vehicle's compliance plate or registration. Most utes and vans are under 3,500 kg.

Test 3: Business identification (signwriting)

Does the vehicle have permanent business identification on the exterior?

Magnetic signs and removable decals do NOT qualify. The signage must be permanently affixed and prominently displayed (clearly visible from a distance).

Test 4: Written restriction

Has the employer issued a written letter of restriction to the employee?

The letter must state the vehicle is not available for private use except for home-to-work travel and incidental business travel. A signed copy should be retained.

Test 5: Compliance monitoring

Does the employer conduct quarterly compliance checks?

IRD specifically expects quarterly checks and documented evidence (logbook reviews, fuel card analysis, GPS data). This is one of the most commonly missed requirements.

Test 6: Actual private use

How is the vehicle actually used outside of business hours?

The double cab ute myth

One of the most persistent misconceptions in NZ tax is that company utes are automatically exempt from FBT. They are not. IRD Deputy Commissioner David Carrigan publicly confirmed in June 2025 that "FBT applies to any company-owned vehicle that's made available for private use, even if that use is occasional. Utes are no exception. This includes double cab utes."

The kernel of truth behind the myth is that utes (including double cabs) CAN qualify for the Work-Related Vehicle (WRV) FBT exemption because they are designed equally for carrying people and cargo, not exclusively for people. But qualifying requires meeting all four IRD conditions, and many businesses fall short on the signwriting, written restriction, or quarterly checks.

The four WRV requirements (all must be met)

1. Vehicle design

The vehicle must NOT be designed exclusively or mainly to carry people. This excludes cars, sedans, SUVs with rear seats intact, and station wagons. It includes:

Double cab utes, extra cab utes, and single cab utes (IRD has confirmed double cabs are dual-purpose)
Vans, panel vans (with no rear seats)
Station wagons, hatchbacks, and 4WDs WHERE the rear seats have been welded down or made permanently unusable (e.g. by permanent shelving)
Taxis (rear seat requirement does not apply to taxis)

2. Permanent business identification

The employer's name or branding must be prominently and permanently displayed on the exterior. Magnetic signs that can be removed do not qualify. Vinyl wraps, paint, or permanent decals are required. The branding must be visible from a normal viewing distance and must remain on the vehicle at all times.

3. Written private use restriction

The employer must provide a written letter to the employee stating the vehicle is not available for private use except for home-to-work travel and travel that is incidental to the business use of the vehicle. This is most commonly a signed letter or a specific clause in the employment agreement. A verbal agreement is not enough.

4. Quarterly compliance checks

The employer must conduct regular checks (IRD recommends at least quarterly) to confirm the restriction is being followed. Common methods:

Logbook reviews
Petrol receipt analysis (looking for purchases at unusual times or locations)
GPS tracking data
Odometer checks against expected business mileage

The checks should be documented (a brief written record of what was reviewed and the conclusion) and kept on file for at least 7 years.

Daily exemption: partial WRV use

The WRV exemption applies on a daily basis. If you allow the employee private use on Saturdays and Sundays, you can still claim the exemption for Monday through Friday and pay FBT only on the weekend days. This is documented through the days available for private use field on the IR420 (capped at 90 days per quarter).

Other vehicle FBT exemptions

Emergency call exemption: No FBT applies for the entire day if the employee uses the vehicle to attend an emergency call (essential services, plant or machinery emergencies, or health and safety emergencies).
Business travel exemption: If the employee is away from home with the vehicle for at least 24 continuous hours on business travel, those days are exempt.
Vehicle unavailable: Days when the vehicle is in the workshop for more than 24 hours are exempt because it's not available for private use.
Heavy vehicles (over 3,500 kg GLW): Outside the standard motor vehicle FBT regime entirely; treated as unclassified benefits.

If you fail the WRV exemption

You are liable for FBT on the vehicle. Use the main FBT Calculator to work out the taxable value, choose between cost price (5% per quarter) or tax book value (9% per quarter, with $8,333 floor) methods using the Method Optimiser, and include the result in your IR420 quarterly return via the Quarterly Estimator.
