How GST works

New Zealand’s Goods and Services Tax (GST) system is often praised for being a simple broad-based tax. But this doesn’t mean mistakes don’t happen.

What is GST?

GST is a tax added to the price of most goods and services, including imports. If you carry out a taxable activity in New Zealand and your turnover is more than $60,000 in a 12-month period, you are required to register for GST. GST is charged at a rate of 15%. ‘Taxable activity’ is generally defined as an activity which is carried on continuously or regularly by any person, and involves the supply of goods and services to another person for consideration.

When do you charge GST?

In general, GST should be charged on most taxable supplies. However, some goods and services are either zero-rated or exempt. Common exempt supplies include renting a residential dwelling and providing financial services, while exported goods/services and land transactions between GST registered persons are examples of zero-rated supplies. For most other goods and services, GST should be charged on the sale. GST can be claimed on goods and services purchased for use in your taxable activity. This means there must be a connection between the taxable supply produced and the good/service a claim is being made on.

Claiming GST

A GST claim can only be made to the extent that the goods and services are used to make a taxable supply, i.e., a supply to which GST applies, including a supply that is zero-rated. As a result, GST-registered taxpayers should be mindful as to whether the good/service they are producing or purchasing is an “exempt” supply or a taxable supply. Furthermore, no GST claim can be made for personal expenditure, as personal expenditure is not connected to a taxable supply.

Take for example a company that has both a commercial investment property and a residential investment property. The supply of residential rental accommodation comprises an exempt supply. Because the company is simultaneously carrying on both a taxable and exempt activity, care needs to be taken to ensure GST is not claimed on expenses relating to the exempt activity, such as GST on the rates and insurance relating to the residential rental.

Where there is an element of both business and exempt use of an asset, the GST claimed on purchase should be apportioned based on the estimated business use. For example, where a phone is purchased in the business, an estimation should be made as how much it will be used privately, and the GST claim should be adjusted accordingly.

Examples of instances where GST is incorrectly claimed include payments for:

• Loan/mortgage principal
• Interest
• Personal drawings
• Construction of residential dwellings that will be held long-term as rentals
• Wages

A common missed opportunity is where a GST-registered person purchases a second-hand good from a non-GST-registered person for use in their taxable activity. In this scenario, a GST credit is claimable by the purchaser, even though GST was not charged by the vendor – e.g., the purchase of a business motor vehicle off TradeMe.

Even though it is called simple and broad-based, having your GST returns periodically independently reviewed is a good idea.

Becoming an employer of choice

15 October 2025

How to attract great people to your business and how to keep them. Three tips to help you rise to the challenge to become an employer of choice.

What the IRD Expects from You as an Employer

10 October 2025

As an employer, there are several obligations and expectations set by the Inland Revenue Department (IRD) that you must adhere to. Understanding these requirements is essential for maintaining compliance and avoiding any potential penalties. Let's take a closer look at what the IRD expects from you as an employer. Register as an Employer Before you hire your first employee, you are required to register as an employer with the IRD. This is a crucial first step in ensuring that you can meet all tax and payroll obligations. Accurate Record Keeping The IRD requires you to keep accurate and detailed records of all employment-related transactions. This includes: Employee personal details Wages and salary paid Payroll dates and methods PAYE deductions and remittances Details of benefits or allowances provided to employees Maintaining proper records helps ensure that you are reporting and remitting the correct amounts to the IRD. Deduct PAYE Tax You are responsible for deducting PAYE (Pay As You Earn) tax from your employees' pay. This involves calculating the correct amount of PAYE and ensuring it is deducted from each employee's salary or wages before their net pay is provided. Pay Employer Contributions In addition to PAYE, you may also be responsible for contributing to your employees' social security and retirement benefits, depending on the country you operate in. These contributions are typically paid in conjunction with PAYE tax. Issue Statements and Forms At the end of the tax year or upon employment termination, you should provide each employee with a statement showing their total earnings and PAYE deductions. Additionally, filing the appropriate end-of-year PAYE schedules with the IRD is required. File Employer Returns Employers are required to file regular returns with the IRD, which could be monthly, quarterly, or annually, depending on specific regulations. These returns should accurately report all payroll activities, including PAYE deductions. Handle Tax Codes and Changes It's crucial to apply the correct tax codes for each employee's circumstances. Any changes in employment status or tax code must be updated promptly to ensure accurate tax withholdings. Comply with Audit Requests The IRD may audit your business to ensure compliance with employer obligations. As such, being prepared to provide all requested information and records in a timely manner is vital. Adhering to these expectations from the IRD is not just about compliance; it's about fostering a transparent and trustworthy relationship with your employees and the tax authorities.
