Preventing Payroll Errors: Five Tips Every Employer Should Know

Payroll mistakes can be expensive. They not only cost your business money, but can also lead to fines or penalties. While some errors are unavoidable, many can be easily prevented with a little attention to detail. Here’s a look at 10 common payroll mistakes and how to avoid them:

1. Misclassifying employees in the payroll system

How you classify your employees in your payroll system directly impacts their tax rates and entitlements. If you get it wrong, you could end up deducting the wrong amounts or even owe your employees wages they should have been paid. For example, misclassifying an employee as exempt from overtime could mean paying them back pay for overtime they were entitled to.

To avoid this, make sure each employee’s details are set up correctly in your payroll system. Double-check that their classification matches their employment contract and that it complies with any specific rules in your industry. Also, remember that contractors have different tax rules to regular employees, so be sure they’re categorised correctly.

2. Using incorrect tax rates

One of the most common payroll errors is applying the wrong tax code or rate. Employees usually provide their tax details, but you should never just assume they’re correct. Mistakes can happen if tax codes aren’t updated, or if an employee forgets to notify you about a change.

To reduce the risk of errors, make it part of your process to confirm tax codes when employees first start and periodically check that the information is up to date.

3. Missing payroll deadlines

Payroll might seem like a simple task, but once you factor in hours worked, leave, overtime, and deductions, it can get complicated. Rushing to meet deadlines can lead to mistakes, and paying employees late can cause frustration and even legal issues.

To stay on top of it, ensure all your employee details (like name, address, tax code, bank info, etc.) are entered correctly and well in advance. Having a clear process to track hours worked and using payroll software that automates payment, and payslip generation, can also make life much easier.

4. Miscalculating or failing to pay overtime

Although there’s no official overtime legislation in New Zealand, many businesses agree to an overtime rate with their employees. If you’re paying overtime, it’s important to make sure your payroll system automatically calculates it based on the agreed rate.

For example, if an employee works over a certain number of hours in a week, the system should apply an overtime rate to those extra hours to ensure they’re paid correctly.

5. Failing to keep payroll records for 7 years

In New Zealand, businesses must keep payroll records for at least seven years. This includes details like how much you pay employees, the deductions you take out, and any contributions you make. Even if you’re a sole trader, keeping detailed records is a must. If the IRD audits your business, you’ll need to show exactly how much you’ve paid your employees, and how taxes were handled. If you don’t have complete records, you could face fines - up to $20,000 for multiple breaches over three months.

By staying on top of these common payroll mistakes, you’ll save your business time, money, and potential headaches. A little planning and organisation can go a long way in ensuring you stay compliant, and keep your employees happy.

Tax planning helps you do more with your money

Tax may be boring, but smart use of tax planning is a superb way to help your business do more with your money.

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.
