Running payroll seems on the surface, like a reasonably straightforward task. You pay people what they're owed, you file what you need to file and everyone moves on. In practice, it's one of the areas where small businesses in New Zealand most consistently come unstuck, and the consequences of getting it wrong go well beyond a slap on the wrist from Inland Revenue.
Here's a clear look at the most common payroll compliance mistakes Kiwi businesses make, and what's actually at stake if you get it wrong.
Payroll is a personal liability. This is not a metaphor.
Most business owners understand that owing money to IRD is not ideal. What they often don't fully grasp is that payroll obligations are in a different category to most other tax debts.
When you run payroll, you're collecting PAYE and KiwiSaver contributions from your employees on behalf of the Crown and your employees' KiwiSaver funds. That money was never yours. You're holding it in trust. Failing to pass it on is not just a compliance failure, its a matter that Inland Revenue can and does pursue as a personal criminal liability.
"Payroll is a personal liability for the employer or the company," says Shelley Dickson - Bookkeeping Team Manager at RightWay. "Failure to pay PAYE or KiwiSaver contributions can result in criminal charges from IRD. It's not your money - it's the employee's money."
That framing is worth sitting with. The contributions you're withholding from an employee's pay are meant to go somewhere: to IRD for their income tax, to their KiwiSaver fund for their retirement savings. If those payments aren't being made, your employee is missing out on money they've earned, contributions they're entitled to, and in the case of KiwiSaver, funds they might be counting on for a home deposit or retirement.
Think about an employee who's been with you for a few years, goes to buy their first home, and checks their KiwiSaver balance to find it's essentially empty because the contributions were never remitted. They have no idea why. That's a serious harm that flows directly from a payroll compliance failure.
Your obligations here should be treated as a higher priority than almost anything else in your business, including paying yourself.
Payday filing: understanding how it actually works
Payday filing was introduced by Inland Revenue to replace the old system of filing employment information once a month. Under the current rules, you're required to file employment information with IRD every single time you run a payroll, not just at the end of the month.
This trips up a lot of small business owners who are still operating as though the monthly filing approach applies, it doesn't.
The key distinction to understand is that payday filing and paying IRD are two different things. You file information with Inland Revenue every pay run, in line with your payroll frequency. But you still only make the actual payment to IRD once a month, by the 20th of the month following. It's the frequency of the reporting that's changed, not the payment timing.
Most modern payroll systems handle payday filing automatically once they're set up correctly. But if your system isn't configured properly, or if you've been managing payroll manually, there's a real chance your filing frequency isn't meeting IRD's requirements. The Inland Revenue website has clear guidance on what's required.
Common errors that create unexpected tax bills
GST does not apply to payroll
This is one of the most consistent DIY bookkeeping errors the RightWay team sees: business owners applying GST to payroll transactions in Xero when they shouldn't be.
Wages and salaries are not subject to GST. They sit outside the GST system entirely. But when you're reconciling transactions yourself and you're not entirely sure which tax code applies to what, it's easy to miscategorise things. The result is that your GST returns end up showing that you owe more GST than you actually do, or in some cases you're incorrectly claiming GST credits that don't exist.
Getting your tax codes right in Xero, particularly around payroll, PAYE, and expenses, is something a qualified bookkeeper can sort out properly once and maintain correctly ongoing.
Incorrect employee setup
When you bring on a new employee, there's a checklist of information you need to get right before you run their first pay. This includes their correct tax code, whether they have a student loan to repay, whether they're opting in or out of KiwiSaver, and whether any other deductions apply like a salary sacrifice arrangement.
Getting any of these wrong from the start means every subsequent pay run is also wrong. Correcting it later means going back through historical records and potentially filing amended returns with Inland Revenue. It's manageable, but it's time-consuming and adds up in professional fees.
Having someone set up your payroll system properly the first time is significantly cheaper than unravelling errors across multiple pay periods.
Using an intermediary payroll provider
One of the most effective ways to manage PAYE risk is to use an intermediary payroll provider.
These providers work by collecting your total payroll payment from you, including your employees' net wages and the PAYE component, then distributing net wages to your employees and remitting the PAYE directly to Inland Revenue on your behalf. Because the money moves out of your account as a single transaction, you're never in a position where PAYE has been withheld from your employees but hasn't been sent to IRD.
This approach takes the cash flow risk largely off the table. IRD is always paid on time. Your employees' KiwiSaver contributions are always being remitted. And you don't have to rely on your own memory or processes to make sure the compliance side is being handled.
It doesn't matter whether you have one employee or twenty, the protection this provides is the same either way.
ACC: don't forget about your employees
ACC levies are another obligation that often gets overlooked, particularly in the early stages of hiring.
As an employer, you're responsible for paying ACC work levies for your employees. The amount is based on the nature of the work your employees do and their liable earnings. ACC will typically contact you once you register as an employer, but if you're not proactively across this, it can catch you by surprise.
Making sure you're in touch with ACC from the outset and factoring their levies into your costs is simply good practice. More information is available at ACC's website for businesses.
Staying ahead of your obligations
The common thread through all of these issues is that payroll compliance rewards preparation and consistent process. The businesses that get into trouble are usually the ones trying to manage payroll on the fly, using systems they haven't properly set up, or relying on their own knowledge in an area that changes and has more nuance than it appears.
Getting your payroll set up correctly from the beginning, using a system that handles payday filing automatically, and having someone qualified either manage or review your payroll on an ongoing basis are the things that keep you on the right side of all of this.
The obligations that come with being an employer are significant. But they're also entirely manageable when you've got the right processes in place.
