Fringe benefit tax (FBT) is a tax your employer pays when they give you non-cash benefits like a company car, health insurance, or a subsidised loan (IRD). You don't pay FBT directly, your employer does. But it costs your employer real money, and that cost shapes what benefits they offer and how they structure your total compensation.
If your employer offers you a $15,000 company car benefit, the FBT on that could cost them an additional $9,590 at the single rate of 63.93% (IRD). That's money they can't put towards your salary. Understanding FBT helps you evaluate job offers and negotiate compensation packages that actually work in your favour.
What is fringe benefit tax?
FBT is a tax on non-cash benefits that employers provide to employees. The logic is straightforward: if your employer gives you something valuable (a car, insurance, a cheap loan), it's a form of compensation, and the government wants tax paid on it. Rather than taxing you on the benefit, NZ taxes the employer directly (IRD).
FBT was introduced in 1985. It exists because without it, employers and employees could avoid income tax by converting salary into non-cash perks. FBT closes that gap.
The important distinction: FBT is the employer's cost, not a deduction from your pay. Your salary stays the same. But the FBT cost often influences whether your employer offers certain benefits at all, and how generous those benefits are.
Who pays FBT? Your employer, but it affects you
Your employer calculates and pays FBT to IRD, either quarterly or annually (IRD). You won't see FBT on your payslip, and it doesn't reduce your take-home pay directly.
But here's the practical reality: every dollar your employer spends on FBT is a dollar they're not spending on your salary, bonus, or other benefits. When an employer evaluates the total cost of your compensation, they factor in FBT. A generous benefits package with high FBT costs means the employer is spending more on you than your salary alone suggests.
This is why some employers offer a "total remuneration" package where you choose how to split your compensation between salary and benefits. In these structures, taking a company car means your cash salary is reduced to offset the car's value and the associated FBT.
Common fringe benefits that attract FBT
Not every perk triggers FBT. The main taxable fringe benefits in NZ are (IRD):
| Benefit | FBT applies? | How it's valued |
|---|---|---|
| Company car (available for private use) | Yes | Cost price method or tax book value method |
| Employer-provided health insurance | Yes | The premium your employer pays |
| Subsidised or interest-free loans | Yes | The difference between market interest rate and what you pay |
| Free or discounted goods/services | Yes | The market value minus what you pay |
| Employer contributions to a non-KiwiSaver fund | Yes | The contribution amount |
| Employer KiwiSaver contributions | No (exempt) | N/A |
| On-premises car parking | No (generally exempt) | N/A |
| Work phones/laptops (primarily for work) | No (exempt if mainly for business) | N/A |
| Supermarket vouchers, gift cards | Yes | Face value |
The "available for private use" test for cars is critical. If a company vehicle is available for you to use privately (even if you don't use it much), FBT applies. It only escapes FBT if it's genuinely not available for personal use, for example, a work van kept at the depot that you're prohibited from driving home (IRD).
FBT rates and calculation methods
Employers can use two main methods to calculate FBT (IRD, 2025-26):
Single rate method
The employer applies a flat rate of 63.93% to the taxable value of all fringe benefits. This is simple but expensive. The 63.93% rate is designed to be equivalent to the top marginal tax rate of 49.25% (39% income tax plus 1.67% ACC, grossed up).
Example: Health insurance worth $2,500 per year.
- FBT at single rate: $2,500 x 63.93% = $1,598
- Total cost to employer: $2,500 + $1,598 = $4,098
Alternate rate method (short form)
The employer calculates FBT based on each employee's actual marginal tax rate (including ACC). This is more complex but can be cheaper when employees are on lower tax rates. The alternate rates are (IRD):
| Employee's income range | FBT alternate rate |
|---|---|
| Up to $15,600 | 11.73% |
| $15,601 to $53,500 | 21.21% |
| $53,501 to $78,100 | 42.86% |
| $78,101 to $180,000 | 49.25% |
| $180,001+ | 63.93% |
Using the alternate rate, the same $2,500 health insurance benefit for an employee earning $70,000 (in the $53,501 to $78,100 bracket):
- FBT at alternate rate: $2,500 x 42.86% = $1,072
- Total cost to employer: $2,500 + $1,072 = $3,572
That's $526 less FBT than the single rate method. Many employers use the alternate rate to reduce their FBT bill.
Company cars and FBT: the most common scenario
Company cars are the most visible fringe benefit, and often the most expensive from an FBT perspective. The taxable value of a company car is based on its cost price (or tax book value) and the number of days it's available for private use (IRD).
Cost price method
The quarterly taxable value is 5% of the car's cost price (including GST), for each quarter the car is available for private use. That works out to 20% of the cost price per year.
Example: Your employer provides a car that cost $60,000 (including GST).
| Item | Calculation | Amount |
|---|---|---|
| Annual taxable value | $60,000 x 20% | $12,000 |
| FBT at single rate (63.93%) | $12,000 x 63.93% | $7,672 |
| FBT at alternate rate (employee on $100K, 49.25%) | $12,000 x 49.25% | $5,910 |
| Total annual cost to employer | Car running costs + FBT | $7,672 to $12,000+ in FBT alone |
What this means for you as an employee
If your employer offers you a company car worth $60,000, they're paying at least $7,672 per year in FBT on top of the car's running costs. In a total remuneration model, that FBT cost comes out of your package. You might get a $100,000 total package with a car, but your cash salary could be $80,000 or less once the car's value and FBT are accounted for.
The question to ask: would you be better off with a higher salary and buying your own car? It depends on the car's value, your tax rate, and how much you'd spend on a car independently. Running the numbers on both options is worth the time.
Employer-provided health insurance and FBT
If your employer pays for your health insurance, the premium is a fringe benefit subject to FBT (IRD). The taxable value is simply the amount your employer pays.
Example: Your employer pays $3,200 per year for your health insurance (Southern Cross or similar).
| FBT method | FBT rate | FBT amount | Total cost to employer |
|---|---|---|---|
| Single rate | 63.93% | $2,046 | $5,246 |
| Alternate rate (employee on $85K) | 49.25% | $1,576 | $4,776 |
For you as the employee, employer-paid health insurance is genuinely valuable. You receive a $3,200 benefit without it being added to your taxable income. The FBT is your employer's problem, not yours. If you'd otherwise buy the same insurance yourself with after-tax dollars, employer-provided cover effectively saves you the income tax you'd pay on the money needed to buy it.
Subsidised loans and FBT
If your employer lends you money at below-market interest rates (or interest-free), the difference between the market rate and what you're charged is a fringe benefit (IRD). The prescribed market interest rate is set by IRD and updated quarterly.
Example: Your employer gives you an interest-free loan of $50,000. The IRD prescribed rate is 8.41% (IRD, as at December 2025 quarter).
| Item | Calculation | Amount |
|---|---|---|
| Annual interest at market rate | $50,000 x 8.41% | $4,205 |
| Interest you pay | $50,000 x 0% | $0 |
| Taxable fringe benefit value | $4,205 - $0 | $4,205 |
| FBT at single rate (63.93%) | $4,205 x 63.93% | $2,688 |
The employer pays $2,688 in FBT on an interest-free loan of $50,000. For you, it's a genuine benefit: you're saving $4,205 in interest per year, and the tax cost falls on your employer, not you.
Benefits exempt from FBT
Not everything your employer provides attracts FBT. Key exemptions include (IRD):
- Employer KiwiSaver contributions: The compulsory employer contribution to KiwiSaver (3%, rising to 3.5% from April 2026 and 4% from April 2028) is exempt from FBT. This was a deliberate policy choice to encourage KiwiSaver membership.
- Contributions to a registered superannuation scheme: Exempt up to certain limits.
- Business tools: Phones, laptops, and other equipment provided primarily for work use are exempt.
- On-premises car parking: Generally exempt.
- Protective clothing and uniforms: Exempt if required for work.
- Employer-provided meals: Exempt if provided in a staff cafeteria on business premises (subject to conditions).
- Certain discounts on employer products: Small discounts on goods your employer sells may be exempt.
The exemption for KiwiSaver contributions is particularly significant. It means employer KiwiSaver contributions are one of the most tax-efficient forms of compensation available in NZ.
What FBT means for your total compensation package
When evaluating a job offer with non-cash benefits, think about total cost to the employer, not just your salary. Here's a simplified comparison:
Job offer A: $100,000 salary, no benefits
| Component | Cost to employer |
|---|---|
| Salary | $100,000 |
| KiwiSaver employer contribution (4%) | $4,000 |
| Total employer cost | $104,000 |
Job offer B: $85,000 salary + company car + health insurance
| Component | Cost to employer |
|---|---|
| Salary | $85,000 |
| KiwiSaver employer contribution (4%) | $3,400 |
| Company car ($50,000, cost price method) | $10,000 taxable value |
| FBT on car (alternate rate, 49.25%) | $4,925 |
| Car running costs (fuel, insurance, rego) | $5,000 (estimate) |
| Health insurance premium | $3,000 |
| FBT on health insurance (alternate rate, 49.25%) | $1,478 |
| Total employer cost | $112,803 |
Job offer B costs the employer nearly $113,000 to deliver, even though your salary is only $85,000. The question for you is whether the car and health insurance are worth the $15,000 salary difference. (Examples use 4% employer KiwiSaver, the rate from April 2028.) If you'd spend $15,000+ per year on a car and health insurance anyway, the benefits package may be the better deal. If you'd buy a cheaper car or skip health insurance, the higher salary could leave you better off.
Common questions
Does FBT come out of my pay?
No. FBT is paid by your employer to IRD. It doesn't appear on your payslip and doesn't reduce your take-home pay. However, in total remuneration packages, the cost of benefits (including FBT) may be offset by a lower salary (IRD).
Is a company car worth it compared to a higher salary?
It depends on the car's value, your driving habits, and your tax rate. A $50,000 company car costs your employer roughly $10,000 in taxable benefit value plus $4,925 in FBT per year (at the 49.25% alternate rate), totalling around $15,000 before running costs. If you'd spend less than that on your own car, a salary increase may be more valuable. If you'd buy a similar car anyway, the company car can be a good deal because FBT is your employer's cost, not yours (IRD).
Do I pay tax on employer-provided health insurance?
You don't pay income tax on employer-provided health insurance. Your employer pays FBT on the premium instead. From your perspective, it's a tax-free benefit. If you bought the same policy with after-tax income, you'd need to earn more than the premium amount to cover it, so employer-provided insurance is effectively worth more than its face value to you (IRD).
What's the FBT rate for 2025-26?
The single FBT rate is 63.93% for the 2025-26 tax year. Employers can also use alternate rates that range from 11.73% to 63.93% depending on each employee's income bracket. Most employers use the alternate rate method to reduce their total FBT bill (IRD).
Can I opt out of a fringe benefit to get a higher salary instead?
That's between you and your employer. Some employers offer flexible packages where you can trade benefits for salary. If your employer offers a company car but you'd prefer cash, it's worth asking. The employer saves on both the benefit cost and the FBT, so there's often room to negotiate (IRD).
Are employer KiwiSaver contributions subject to FBT?
No. Employer KiwiSaver contributions are exempt from FBT. This makes KiwiSaver contributions one of the most tax-efficient forms of employer-provided compensation in NZ (IRD).
Does FBT apply to working from home allowances?
It depends on how it's structured. If your employer pays you a cash allowance for working from home expenses, it's generally treated as part of your salary (taxed through PAYE), not as a fringe benefit. If your employer provides you with equipment (desk, chair, monitor) for home use, FBT may apply depending on the value and whether the items are primarily for work purposes (IRD).
My employer gives me a fuel card. Is that subject to FBT?
If the fuel card is for a company vehicle that's subject to FBT, the fuel cost is already included in the FBT calculation on the vehicle. If it's a standalone fuel card for your personal vehicle, the value of fuel purchased is a fringe benefit subject to FBT (IRD).
