IR56 Payer New Zealand: What It Means for Nannies and Families

If you've been looking into how to pay a nanny in New Zealand, chances are you've stumbled across the term IR56 payer. It's not a phrase most people come across in everyday life, and Inland Revenue's own paperwork doesn't always make it easy to understand. So what does it actually mean, and is it something your family should be using?

In short, an IR56 payer, more formally known as an IR56 worker or IR56 taxpayer, is someone who earns wages without having PAYE deducted by their employer. Instead of the employer sorting out tax at the time of payment, the worker takes on that job themselves. It's a genuine option recognised by Inland Revenue, but it comes with more moving parts than most people expect.

What does being an IR56 worker actually involve?

The IR56 worker is still legally an employee. That distinction matters, because it means they're entitled to things like annual leave and public holidays, not just a wage. What sets them apart from a typical employee is that they, rather than their employer, are on the hook for working out and paying their own PAYE.

According to Inland Revenue, this means registering as an IR56 worker, calculating tax each pay period, and filing employment information within 10 working days of the end of the month the pay was earned. Payment to Inland Revenue is then due by the 20th of the following month. Anyone managing KiwiSaver contributions has to fold that into the same process. It's essentially a mini payroll run that one person has to carry out on their own, month after month, on top of their actual job.

Does IR56 apply to nannies?

It can, but only in specific circumstances. Inland Revenue treats nannies as a type of private domestic worker, a category that also covers home helpers, caregivers and gardeners working in someone's private home. To qualify, the work needs to be unrelated to the family's business, the nanny has to be paid directly by the family, and crucially, the nanny must work under 30 hours a week on average for that particular employer.

Take a nanny who splits her week between two families, working 14 hours for one and 18 for the other. Because neither arrangement crosses the 30 hour threshold, she could be classified as an IR56 worker, responsible for her own tax with each family.

Compare that to a nanny working 40 hours a week for a single family. That's full-time employment, and it takes her out of IR56 territory altogether. The family becomes the employer in the usual sense: registering with Inland Revenue, deducting PAYE, and filing payday reports as any other employer would.

Who else can be an IR56 worker?

Nannies are one of the more visible examples, but the IR56 category was built for a handful of unusual working arrangements. It also applies to home helpers, caregivers, gardeners in private homes, New Zealand based staff working for overseas employers, embassy employees, and workers on the United States Antarctic Program. Outside of these situations, most people in New Zealand will never deal with IR56 at all, since their employer handles PAYE through the standard payroll system.

The catch with managing it yourself

Being an IR56 worker is entirely legal, but it shifts a fair amount of admin onto one person's shoulders. Rather than being paid a net wage and moving on, that person has to work out PAYE correctly every month, register and file with Inland Revenue on time, manage KiwiSaver if it applies, and keep records that would hold up to scrutiny.

For someone without a background in payroll or tax, this can eat into time that would otherwise go toward, well, actually looking after children. And the margin for error isn't forgiving. A missed filing deadline or a miscalculated PAYE amount can mean unexpected interest or penalties landing on the worker, not the family.
