FBT Explained: Fringe Benefit Tax for NZ Small Business

If your business provides employees — including yourself as a shareholder-employee — with benefits beyond their salary, fringe benefit tax (FBT) may apply. It is one of the more complex areas of New Zealand tax, and one that catches many small business owners off guard.

Here is a plain-language guide to how FBT works, what triggers it, and how to manage it.

FBT is a tax paid by employers on non-cash benefits provided to employees. The idea is straightforward: if an employee receives something of value from their employer that is not cash wages, it should be taxed — otherwise it would be a way to pay people without paying income tax.

The employer pays FBT (not the employee), and it is calculated based on the value of the benefit provided.

FBT applies to benefits provided to:

• Employees (including part-time and casual employees)
• Shareholder-employees (directors who also work in the business)
• Associates of employees (e.g. a spouse who uses a company car)

This is the most common FBT trigger for small businesses. If a company vehicle is available for an employee's private use — even if they do not actually use it privately — FBT applies.

"Available for private use" is broadly interpreted. If the vehicle goes home with the employee at night, FBT applies. If it is parked at the business premises and genuinely not available for private use, FBT may not apply — but you need to be able to demonstrate this.

If your company lends money to an employee (or shareholder-employee) at below the IRD prescribed interest rate, the difference is a fringe benefit.

Providing employees with your business's products or services at a discount or for free can trigger FBT, depending on the value.

If the company pays health insurance premiums for employees, this is a fringe benefit subject to FBT.

Subsidised gym memberships, club memberships, or recreational facilities provided to employees are generally subject to FBT.

Certain share scheme benefits are subject to FBT.

Not everything an employer provides is subject to FBT. Exempt benefits include:

• Work-related vehicles used only for business purposes (with no private use)
• On-premises car parking (in most cases)
• Employer contributions to KiwiSaver (these are subject to employer superannuation contribution tax, not FBT)
• Meals provided on business premises during work hours (in limited circumstances)
• Safety equipment required for the job
• Small gifts under certain thresholds (the rules here are nuanced)

FBT is calculated on the taxable value of the benefit, using one of two methods:

A flat rate of 63.93% is applied to the taxable value of all benefits. This is simple but can result in overpayment if employees are on lower tax rates.

Benefits are attributed to specific employees and taxed at rates that correspond to their income level. More complex but potentially lower FBT liability.

Most small businesses use the single rate method for simplicity.

Example — company car: IRD uses a formula to calculate the taxable value of a motor vehicle benefit:

• 20% of the vehicle's cost price (or tax book value) per year
• Divided by the number of pay periods

For a vehicle that cost $40,000:

• Annual taxable value: $40,000 × 20% = $8,000
• FBT at 63.93%: $8,000 × 63.93% = $5,114 per year

This is a significant cost that many business owners do not factor in when deciding to provide a company vehicle.

FBT returns are filed quarterly (or annually if your FBT liability is under $500,000 per year and you elect annual filing). The due dates for quarterly returns are:

• 31 July (quarter ending 30 June)
• 31 October (quarter ending 30 September)
• 31 January (quarter ending 31 December)
• 31 May (quarter ending 31 March)

Annual FBT returns are due 31 May.

This is where FBT gets particularly relevant for small business owners. If you are a shareholder-employee — meaning you own shares in the company and also work in it — benefits you receive from the company are generally subject to FBT.

This includes the company car you drive, the health insurance the company pays, and any other non-cash benefits you receive.

Some owner-operators try to avoid FBT by treating these benefits as shareholder drawings or personal expenses. This is not correct and can create compliance issues. If the company is providing you with a benefit, FBT applies.

For some businesses, the answer is yes — the benefit to employees (or yourself) outweighs the FBT cost. For others, it is more tax-efficient to pay a higher salary and let employees purchase their own benefits.

The calculation depends on:

• The value of the benefit
• The employee's marginal tax rate
• Whether the benefit is something the employee would buy anyway

For example, if an employee is on a 33% marginal rate and the company provides a benefit worth $1,000, the FBT cost is $639. The employee would have needed $1,493 in gross salary to buy the same benefit after tax. In this case, providing the benefit directly is more efficient.

Your accountant can model this for specific benefits you are considering.

1. Identify all benefits your business provides to employees and shareholder-employees
2. Determine which are subject to FBT — not all benefits are taxable
3. Calculate the taxable value using IRD's prescribed methods
4. File and pay FBT returns on time — late filing penalties apply
5. Review annually — the FBT rules change periodically, and your benefit mix may change

If you have a company vehicle and have never filed an FBT return, it is worth reviewing your position urgently. This is one of the areas IRD audits regularly.
