GST stands for Goods and Service Tax in New Zealand. It’s collected by businesses on behalf of the Inland Revenue Department (IRD). Business owners should be familiar with GST, including the GST rate, how to calculate GST, how to register for GST, and more.​

GST is 15% added to the goods and/or services you sell in New Zealand. However, a rate of 0% may apply and some goods or services can be GST-exempted in some situations. You can find more use cases by reading our GST on special transactions guide.​

There are a couple of formulas you need to remember when calculating GST. ​

To calculate a GST-inclusive price, multiply the price of goods and/or services by 1.15. For example, if the net sale price of your good is $100, the GST inclusive price is $115 ($100 * 1.15).​

To calculate a GST-exclusive price, divide the price of goods and/or services by 1.15. For example, if the total gross sale price of your service is $230, the GST exclusive price is $200 ($230/1.15).​

GST may seem simple to work out, however, mistakes can easily be made - use this GST calculator to be error-free!​

It's always best to consult with a tax professional or refer to the IRD's detailed guidance if you have specific questions about whether a particular good or service is exempt from GST.​

In New Zealand, the GST registration threshold is $60,000 per year. If your business’s annual turnover or expected annual turnover exceeds $60,000 per year, you’re required to register for GST. If your business’s annual turnover doesn’t meet the GST registration threshold, becoming GST-registered is voluntary.​

There are two ways to register for GST:​

If you operate your business as a sole trader, your GST number should be the same as your personal IRD number. If you operate through a partnership or company structure, your partnership or company’s GST number will be the same as your partnership or company’s IRD number.​

Once you’ve become GST-registered, you need to meet your responsibilities, these include:​

GST rules in the sharing economy can be tricky as it depends on what services you offer.​

As of 1st April, 2024, new rules apply to those providing services like rideshares, accommodation, or food delivery through online platforms (e.g. Uber, Airbnb, DoorDash).  ​

You can opt out of the new GST rules and manage your own GST responsibilities if:​

Certain services, like cleaning or dog walking, are exempt from these new rules.​

When it comes to imported goods, GST is typically collected by New Zealand Customs. Generally, you’ll need to pay 15% GST on top of the purchase price. However, if your goods are valued below $1,000, you don’t need to pay GST to Customs. ​

To get a clearer idea of the potential GST you might owe on your imported goods, try our handy GST calculator above. Keep in mind that you might also need to pay customs fees in addition to GST. So, the total amount you pay to Customs will be the GST on your imported goods plus customs fees (if any).​

For exported goods overseas, these sales are generally zero-rated for GST. This means you don’t charge GST on your sales but still can claim back the GST proportion on related expenses, such as shipping and manufacturing costs. It’s worth noting that these zero-rated sales still need to be disclosed in your GST returns.​

Your GST return and payment due dates can be monthly, two-monthly, or annually, and it depends on your business’s annual turnover. ​

For example, businesses that have a turnover above $24 million are required to file their GST on a monthly basis. Two-monthly is for businesses that have a turnover of up to $24 million. You should always ask your accountant if you’re unsure about your filing frequently. If your business turnover is below $500,000 a year, you can choose to file GST every six months.​
