Fringe Benefit Tax for NZ Tradies: Company Vehicles, Tools and IRD 2026

If you're a tradie running through a limited company — and a lot of you are — there's a tax many forget about until IRD comes knocking. Fringe Benefit Tax (FBT) applies when your company provides benefits to you as an employee, and the most common trigger is the company ute sitting in your driveway at night.

IRD has been stepping up FBT compliance activity in 2026, particularly targeting the construction and trades sector. Getting this wrong means penalties, back-tax, and use-of-money interest at 10.91% per annum. Getting it right means your company structure stays tax-efficient and bulletproof under scrutiny.

Here's what you need to know.

What Is FBT and Who Pays It?

Fringe Benefit Tax is a tax paid by employers on non-cash benefits they provide to employees. If you're a sole trader, FBT doesn't apply — but if you're a company director and shareholder who draws a wage (even $0), your company is the employer and you're the employee. That means company-provided vehicles, tools, phones, and fuel cards can all trigger FBT.

FBT is governed by the Income Tax Act 2007 and administered by Inland Revenue (ird.govt.nz). It's not a new tax, but it catches many tradies off-guard when they first move from sole trader to company structure. If you're still weighing that decision, see our sole trader vs company guide for the full breakdown.

The Company Vehicle Problem

The single biggest FBT issue for NZ tradies is the company vehicle made "available for private use." Under IRD rules, a vehicle is available for private use if:

• It's taken home overnight
• It can be used for personal errands
• No documented restriction on private use exists

For most tradie companies, the ute goes home with the owner every night — which IRD treats as private use availability, regardless of whether you actually drove it to the supermarket.

How much does FBT cost on a vehicle?

FBT on a motor vehicle is calculated on the cost price or tax value of the vehicle:

The resulting "taxable value" is then multiplied by the FBT rate to calculate tax owing. Using the standard FBT rate of 49.25%, here's what a $55,000 company ute costs in FBT:

• Taxable value per quarter: 5% × $55,000 = $2,750
• FBT payable per quarter: $2,750 × 49.25% = $1,354
• Annual FBT bill: approximately $5,415

That's over $5,000 per year in extra tax — just for taking the ute home. If you're a shareholder-employee earning over $129,681, the alternate rate applies and your FBT rate rises to 63.93%, pushing the annual bill closer to $7,000.

The Work-Related Vehicle Exemption

Here's the good news: many tradie vehicles qualify for the work-related vehicle exemption under section CX 17 of the Income Tax Act 2007. If your vehicle qualifies, no FBT applies.

A vehicle is exempt if:

1. It is a utility vehicle, van, or other vehicle not ordinarily used as a private passenger vehicle
2. It is not made available for private use — except travel between home and work
3. Your company has a documented policy restricting private use

For most tradies, a ute, van, or truck will meet criteria 1 and 2. The critical step is having a written vehicle use policy signed by yourself as both director and employee. IRD expects to see this documentation if audited. A one-page policy stating the vehicle is restricted to business use and home-to-work travel is enough — but it must exist in writing.

Note: ordinary passenger cars do not qualify for this exemption. If your company owns a Toyota Corolla used as a site runner, FBT applies.

Tools, Phones, and Other Benefits

Vehicles aren't the only FBT trigger. Other common tradie benefits include:

Work tools and equipment: Tools provided by a company are generally FBT-exempt if used mainly for work purposes. There's no FBT on a drill set or circular saw that lives in the work van. However, tools taken home regularly for personal use can attract FBT if private use is more than incidental.

Mobile phones: A single phone provided to an employee for business use is FBT-exempt. Problems arise if the company pays for a personal upgrade or the family plan. Keep it to one business phone per employee and retain records showing business use.

Fuel cards: If your company issues a fuel card, fuel used for private travel is a fringe benefit. Many tradie companies avoid this by reimbursing actual business fuel costs rather than issuing an open-ended card. See our vehicle expenses guide for how IRD expects you to split private and business costs.

Low-value benefits exemption: IRD allows a de minimis exemption — benefits under $300 per quarter per employee (up to $1,200 per year) are FBT-exempt. This covers the occasional safety gear purchase or staff shout without triggering FBT paperwork.

FBT Filing Deadlines for 2026

FBT is filed quarterly with IRD. For the 2025/26 year:

If you've been providing a vehicle to yourself as a company director and haven't filed FBT, Q4 was due 31 May 2026 — this week. Contact IRD immediately if you've missed it. Voluntary disclosure before IRD contacts you reduces shortfall penalties from 20% to 10%, and in some cases eliminates them entirely.

Annual filing is available for smaller employers with an FBT liability of $500 or less per year — worth checking with your accountant if your only FBT exposure is a single exempt ute.

What IRD Is Looking For in 2026

IRD's construction sector compliance programme focuses heavily on:

• Company vehicles where no FBT has been filed despite the vehicle clearly being taken home
• Shareholder-employee benefits not disclosed in tax returns
• Informal tool or vehicle allowances paid to workers off the books

Data matching between vehicle registration records, company returns, and FBT filings makes it straightforward for IRD to identify companies with registered vehicles but no FBT history. The risk of audit has risen meaningfully for tradie companies.

The best protection is clean documentation: a written vehicle policy, a mileage log if using the tax value method, and consistent quarterly FBT returns.

Getting Your Numbers Right

If you're unsure about your FBT exposure, start by modelling your overall tax position using the GST calculator at tradietools.nz. Then make sure your job pricing accounts for the real cost of running a company vehicle — our hourly rate calculator includes a section on vehicle running costs that you can adjust to include FBT.

Most tradie accountants can run a free FBT health check. It's worth a 30-minute call before IRD makes contact — the cost of sorting it out proactively is a fraction of the penalties and back-tax if you're caught out.
