Common payroll mistakes to avoid

6 December 2022

When you’re managing payroll, you can’t really afford to get it wrong. Best case scenario, the mistake costs you time and money. Worst case, it can result in legal issues as well. Payroll mistakes can and do happen, so here’s some mistakes to watch out for.


1. Bonuses & Annual Leave

This can be a tricky one to get right. The Holidays Act 2003, states that holiday pay is calculated based on an employees’ gross earnings – INCLUDING any productivity or incentive-based payments. An incentive-based bonus for achieving a particular outcome, should be included as part of the gross earnings. However, one-off no-obligation bonuses, not tied to productivity or incentive, are not.


2. Casual Contracts

Some businesses leave staff on casual contracts when they’re no longer a casual worker. Although there’s no legal definition for a casual worker, Employment NZ, says the term applies to an employee who “has no guaranteed work hours, no regular pattern of work, and no ongoing expectation of employment.” This means there’s no obligation for you to offer work, and there’s no obligation for them to accept work. Annual holidays and leave are managed differently for casual employees – usually they are paid an additional 8% on top of their wages/salary.

This is all well and good as long as that employee is truly a casual employee. As soon as an employee starts a regular work pattern, then he/she becomes a permanent part-timer and is entitled to annual holidays.


3. Making payroll deductions

Deducting money from an employee’s wages is protected by law. Under The Wages Protection Act 1983, you can only make deductions from an employee’s pay if it’s required by law, such as tax, student loan repayments, or child support. You can also make deductions if the employee explicitly agrees (and not under duress). If you make a payroll mistake and overpay an employee, you can’t just deduct it from the next pay. You need to consult your employee before making any specific deductions and he/she can withdraw his/her consent for you to do so, at any time. So before making any payroll deductions that aren’t for tax, student loan, or child support, make sure to get consent (ideally written) from your employee.


4. Final Pay Calculations

Final pay calculations can be a bit of a headache, especially when employees are entitled to be paid for public holidays that occur after their termination date. It applies to employees who’ve worked for you for at least 12 months and is a result of unused annual holiday entitlement.

To work out if this rule applies, imagine that your employee is taking his/her annual leave from the day after employment with you has ended. If there is a public holiday within that period (on a day when the employee would normally have worked), then you must pay for that public holiday, as you usually would.

You must also extend the period the annual holidays covers by one day for each public holiday.


5. Using Integrated Systems

Payroll mistakes are commonly made because employers get confused about employment law and employee entitlements. An integrated payroll system can help avoid payroll mistakes, especially if you’re using multiple systems to record HR info, timesheets, and payroll. Integrating a payroll system with other software can make payroll a much simpler process!

Is your business structure still the right fit?
3 July 2026
Your business structure plays an important role in how your business operates, how profits are taxed, how decisions are made, and how much personal risk you may be exposed to. For many businesses, the structure chosen at the start made sense at the time. But as your business grows or changes, it is worth asking whether that structure still supports where you are now - and where you are heading. The three most common business structures are sole trader, partnership and company. Each has different cost, administration, tax and liability considerations. Operating as a sole trader A sole trader structure is where one person owns and runs the business. The main benefit is simplicity. It is easy to set up, and from a tax perspective, business profits or losses are included in your personal tax return. Being a sole trader also does not prevent you from employing staff if your business grows. However, this structure can carry more personal risk. Sole traders generally have unlimited liability, which means if the business runs into financial or legal trouble, you may be personally liable. This makes the right insurance and risk management especially important. A sole trader structure can also become limiting if you want to bring in other owners, attract investment, or prepare the business for sale. Working within a partnership A partnership is where two or more people go into business together. Partnerships can be a practical way to combine skills, knowledge, resources and capital. They are usually relatively simple to set up and manage, although it is important to have a clear partnership agreement in place. This should document how profits are shared, how decisions are made, and what happens if one partner wants to leave or circumstances change. From a tax perspective, partnership profits are generally not taxed at the partnership level. Instead, each partner includes their share of the profits in their own personal tax return. The main risk is that partnerships do not offer the same legal separation as a company. In many cases, partners may be liable for partnership debts jointly and severally. There are ways to reduce this risk, such as using a limited partnership, but this should be considered carefully with the right professional advice. Operating as a company A company is a separate legal entity from its owners, who are known as shareholders. One of the key advantages of a company structure is limited liability. In many cases, a shareholder’s financial liability is limited to the amount they have invested in the business. A company structure can also be useful if you want to bring in investors, introduce new shareholders, or sell the business in future. However, companies usually come with higher administration and compliance requirements than a sole trader or simple partnership structure. This includes annual accounts, tax returns, Companies Office requirements and other record-keeping obligations. It is also important to remember that company funds belong to the company, not personally to the directors or shareholders. Money is usually taken out through salary, dividends, drawings or director loan accounts, depending on the circumstances. Getting this right is important from both a tax and cashflow perspective. When should you review your structure? It may be worth reviewing your business structure if: your business has grown or become more complex you have taken on staff, debt, assets or higher levels of risk you are considering bringing in another owner or investor you are planning to sell, exit or pass on the business your personal circumstances have changed you are unsure whether your current structure is still tax-effective or appropriate Is your current structure still working for you? There is no one-size-fits-all answer when it comes to business structure. The right option depends on your business, your goals, your risk profile and your future plans.
