The cost of a perk the employer carries

Fringe Benefit Tax is the tax an employer pays on the non-cash extras it gives staff. The classic example is a work vehicle available for private use, but it also covers subsidised goods and services, low-interest staff loans, and contributions to certain insurance or superannuation schemes. The logic is straightforward: if an employer could dodge PAYE by paying people in cars and cheap loans instead of salary, the tax base would leak, so FBT taxes those benefits to keep things even. Importantly, FBT is the employer’s liability, not the employee’s, so the staff member enjoys the benefit without a tax bill of their own.

This calculator applies the single FBT rate to the taxable value of a benefit. You enter the GST-inclusive value of the benefits provided, and it returns the FBT payable plus the total cost of providing that benefit once the tax is added on. It is aimed at employers, bookkeepers and contractors trying to understand the true cost of putting a ute or a perk on the books.

FBT on a $12,000 work-vehicle benefit

Suppose a work vehicle’s private-use benefit is valued at $12,000 for the year, GST inclusive. The single FBT rate is 49.25 percent, so the tax is 49.25 percent of $12,000. That is $5,910. Add it to the benefit and the vehicle perk costs the business $17,910 in total.

That high rate surprises a lot of business owners. The chart shows just how much tax sits on top of the benefit itself.

Single rate versus the attribution method

The 49.25 percent single rate is the simple option, and it is what this tool uses. It is set high deliberately, because it has to work for employees on the top 39 percent income rate. For a workforce that includes lower-paid staff, the single rate over-taxes their benefits. That is where the alternate-rate, or attribution, method comes in. It lets an employer calculate FBT at a rate aligned to each employee’s actual marginal tax rate, which usually lowers the bill for a business with a spread of incomes. The trade-off is paperwork: attribution requires an end-of-year calculation per employee, so many small employers stick with the single rate for simplicity and accept the higher cost.

Exemptions and the work-related vehicle carve-out

Not every vehicle triggers FBT. A genuine work-related vehicle, typically a sign-written ute or van that the employer prohibits from private use except for travel between home and work, can be exempt on the days that test is met. Get the documentation right, including a written private-use restriction and occasional checks, because Inland Revenue can reassess if the rule is ignored in practice. There are also de minimis thresholds for minor unclassified benefits, so the occasional small gift does not necessarily attract FBT. The common mistake is assuming the company car is automatically exempt because it has the business logo on the door. Exemption depends on the private-use restriction being real and enforced, not on the paint job. If staff take the vehicle home and use it for the weekend, FBT applies.

How often is FBT paid?

Most employers file and pay FBT quarterly, though smaller employers can elect an annual or income-year basis if they qualify. Quarterly filing spreads the cost and keeps the calculation closer to when the benefit is provided. If your only benefit is a single company vehicle, the annual option can cut down on admin, but check your total benefit value stays within the eligibility limits.

Is FBT deductible for the business?

Yes. Both the cost of providing the benefit and the FBT paid on it are generally deductible business expenses, so the company gets income tax relief at 28 percent on the outlay. That softens the headline cost, but it does not eliminate it, since a deduction only returns the tax rate, not the whole amount. Factor the FBT into the true cost of any salary-packaged perk before offering it.

Frequently asked questions

What is Fringe Benefit Tax?
FBT is paid by employers on non-cash benefits given to staff, most commonly a work vehicle available for private use, subsidised goods, or low-interest loans. The single rate is 49.25% on the GST-inclusive taxable value, though employers can instead use the alternate-rate (attribution) method to align FBT with each employee marginal rate. This tool uses the single rate.
Who pays FBT and when is it due?
FBT is always the employer liability, not the employee. Most employers file quarterly returns with Inland Revenue on 20 July, 20 October, 20 January, and 20 May. Smaller employers may elect an annual or income-year basis if their total FBT liability in the previous year was $500,000 or less. Annual filers pay by 20 May following the end of the income year.
Are KiwiSaver employer contributions subject to FBT?
No. Compulsory employer contributions to KiwiSaver are not a fringe benefit. They are subject to Employer Superannuation Contribution Tax (ESCT) instead, which is deducted at source by the employer and paid to Inland Revenue. Voluntary employer contributions above the compulsory 3% minimum may also be subject to ESCT rather than FBT, depending on the arrangement.
Can a work vehicle ever be exempt from FBT?
Yes, under the work-related vehicle exemption. The vehicle must be a type listed in the Income Tax Act 2007 (such as a van, ute, or truck), it must be sign-written with the employer business name or logo, and the employer must have a written policy prohibiting private use except for travel between home and a workplace. If the restriction is genuine and enforced, days the vehicle is used solely for work are exempt. Inland Revenue can reassess where private use restrictions exist on paper but are not followed in practice.
