What NZ Small Business Owners Need to Know Before Taking On Their First Employee

Taking on your first employee is a significant milestone. It's also the point where a lot of NZ business owners discover they've underestimated the compliance obligations that come with it.

Getting payroll right from day one is much easier than fixing it later.

As an employer, you're responsible for deducting income tax from your employees' wages and paying it to IRD on their behalf. This is PAYE. You need to register as an employer with IRD before you pay your first employee.

The amount you deduct depends on the employee's tax code, which they provide on an IR330 form when they start.

If your employee is eligible for KiwiSaver (most NZ residents aged 18–65 are), you're required to:

• Automatically enrol new employees unless they opt out within the first 56 days
• Deduct employee contributions from their wages (3%, 4%, 6%, 8%, or 10% — employee's choice)
• Pay employer contributions of at least 3% of their gross wages
• Pay the employer superannuation contribution tax (ESCT) on those employer contributions

Under the Holidays Act, employees are entitled to four weeks' annual leave after 12 months of employment. Holiday pay accrues from day one and needs to be calculated correctly — the Holidays Act is notoriously complex and has caught out many NZ employers.

Since 2019, all NZ employers are required to file employment information with IRD every payday — not monthly. This means submitting an Employment Information (EI) return within two working days of each payday.

Not registering as an employer before the first payday. IRD requires you to be registered before you pay anyone. Paying wages without being registered creates a compliance problem.

Getting the tax code wrong. If an employee doesn't provide a tax code, you're required to deduct at the no-notification rate (45 cents in the dollar). Make sure every new employee completes an IR330.

Miscalculating holiday pay. The Holidays Act requires holiday pay to be calculated as the greater of ordinary weekly pay or average weekly earnings. Getting this wrong can result in underpayment claims.

Missing payday filing deadlines. Late or missed EI returns attract penalties.

Payroll software like Xero Payroll or MYOB can automate most of the calculations and filing. But the setup needs to be correct — wrong tax codes, incorrect KiwiSaver rates, or misconfigured leave settings will produce wrong results automatically.
