Pre‑Tax Public Transport in NZ: What Employers and Payroll Teams Need to Know

Learn how IRD‑approved pre‑tax public transport works, what payroll needs to do, and how employers can stay compliant while supporting staff.

Pre‑Tax Public Transport: What NZ Employers Need to Know (and How Payroll Fits In)

With fuel prices continuing to bite and more employers looking for meaningful ways to support their teams, you may have heard talk about pre‑tax public transport benefits and platforms like Extraordinary.

So what does this actually mean for New Zealand employers and payroll teams?
Is it legit?
Is it taxable?
And does payroll need to do anything differently?

Let’s break it down.

What is the pre‑tax public transport benefit?

In New Zealand, employers can provide public transport commuting costs to employees without incurring Fringe Benefit Tax (FBT) — and, in some cases, employees can effectively pay for public transport using pre‑tax income.

This is possible because the Income Tax Act includes a specific FBT exemption for employer‑subsidised public transport, covering fares that are mainly for travel between home and work (bus, train, ferry, cable car).

Until recently, the challenge wasn’t the law — it was the practical implementation. It was difficult for employers to offer this benefit in a way that was controlled, compliant, and workable through payroll.

That changed when Inland Revenue issued a binding Product Ruling approving a specific structure and platform to make this possible.

Enter: Extraordinary

Extraordinary Pay Limited is currently the only provider with an IRD Product Ruling that specifically supports public transport benefits delivered either:

via salary sacrifice (pre‑tax), or
as an employer‑funded subsidy

…without triggering FBT when used correctly.

The ruling (BR Prd 25/03) confirms that the arrangement is compliant provided the funds are:

restricted to approved public transport only, and
set up as a valid salary‑sacrifice or compensation arrangement.

Employees can use the benefit to top up public transport cards such as:

AT HOP
Snapper
Metrocard
Bee Card

No petrol, no parking, no tolls — public transport only.

How does this work through payroll?

This is where most of the questions come from — and thankfully, the answer is reasonably straightforward.

Step 1: Employee opts in

The employee chooses a fixed amount to contribute (for example, $20 per week).

This must be:

voluntary, and
agreed in advance (usually via an employment agreement variation or salary‑sacrifice agreement).

Step 2: Payroll applies a pre‑tax salary reduction

Payroll reduces the employee’s gross pay by the agreed amount.

Important point:
PAYE, ACC, student loans, and KiwiSaver are calculated on the reduced gross, not the original amount.

The sacrificed amount is not taxable income.

Step 3: Funds are paid to the provider

The employer sends the reduced amount to Extraordinary as part of the payroll process (either via integration or payment run).

Extraordinary credits the employee’s account.

Step 4: Employee uses the funds

Funds are locked and can only be used to top up approved public transport cards.

There is no ability to withdraw cash or spend the money elsewhere.

Two ways employers can offer this benefit

1. Salary sacrifice (most common)

Employee gives up part of their gross pay
Employee gets the tax saving
Employer is generally cost‑neutral (aside from administration)

~ No PAYE on the sacrificed amount
~ No FBT
~ No ESCT
~ No ACC on the sacrificed amount

2. Employer‑funded subsidy

Employer pays the cost as part of total remuneration
Employee pay does not reduce
Still FBT‑exempt if conditions are met

~ Still no FBT
~ Employer bears the cost

What payroll teams need to do

Payroll does need to:

Set up a pre‑tax salary‑sacrifice deduction code
Ensure employment agreements or variations support the arrangement
Send the correct amounts to the provider
Keep records of employee consent

Payroll must not:

Treat the amount as taxable pay
Include it in PAYE calculations
Run it through FBT
Allow retrospective sacrifices

Important compliance points to be aware of

Minimum wage still applies

Salary sacrifice cannot reduce an employee’s pay below minimum wage.
This is especially important for:

lower‑paid employees, and
salaried staff with variable hours.

This is not fuel relief

Despite increased talk about fuel costs, this benefit:

applies to public transport only
does not apply to petrol, parking, or private vehicle costs

Any cash fuel support paid through payroll would generally be taxable.

Provider structure matters

Trying to DIY this (for example, reimbursing AT HOP top‑ups directly) can easily:

trigger PAYE or FBT, and
create compliance risk.

The Product Ruling is what makes the Extraordinary structure work.

Why we’re seeing more questions about this

With:

high fuel prices,
pressure on household budgets, and
employers looking for practical, tax‑efficient benefits,

public transport is one of the few areas where the tax system currently allows meaningful relief without increasing wage costs or triggering extra tax.

That’s why this topic is popping up more frequently in payroll and HR discussions.

The Ontrack Group takeaway

Pre‑tax public transport benefits can work well for the right employers — but only when:

the structure is compliant,
payroll is set up correctly, and
minimum wage and salary‑sacrifice rules are respected.

If you’re considering this option, it’s worth getting advice upfront to avoid unintended tax consequences.
