New Zealand Goods and Services Tax Overview

In New Zealand, the Goods and Services Tax (GST) is a value-added tax that applies to most goods and services. The Goods and Services Tax (GST) was created to make taxes easier to understand and ensure that everyone pays their fair share.

The GST rate in New Zealand is 15% right now, and it applies to practically all goods and services, even those that are brought in from other countries. If you’re a business owner, contractor, freelancer, or just a regular shopper, it’s important to know about GST so you can set the right prices, keep your books straight, and pay your taxes on time. In New Zealand, a GST calculator can help you speed up calculations, with fewer mistakes, and save time when you make invoices, expense reports, or GST returns.

What Is GST in New Zealand?

Goods and Services Tax (GST) is New Zealand’s consumption tax, applied to most goods and services sold domestically. Introduced in 1986, GST helps fund public services across the country. The tax is collected by businesses on behalf of the government and is ultimately paid by the end consumer.

In New Zealand, the standard GST rate is 15%. This rate applies to everyday items such as retail goods, professional services, accommodation, digital products, restaurant meals, and most business transactions. Imported goods and services can also attract GST under specific IRD rules.

Businesses add GST to their prices (GST-inclusive), then file GST returns with Inland Revenue to pay the collected amount — after deducting any GST they have paid on business expenses (GST credits). This ensures GST is only charged on the value added at each step in the supply chain. Read More About GST Tax on Wikipedia

Common examples where GST applies:

  • Retail products

  • Trades and contractor services

  • Online or digital services

  • Import duties (where applicable)

  • Business-to-business sales

Some transactions, however, are zero-rated or exempt, which changes how GST is charged and claimed. (See detailed section below.)

GST Calculation Formulas and Methods

To use the GST Calculator effectively, it’s helpful to understand the formulas:

  • Adding GST:
    GST-exclusive amount × 1.15 = GST-inclusive amount

  • Extracting GST from total:
    GST-inclusive amount × 3 ÷ 23 = GST amount

  • Removing GST:
    GST-inclusive amount ÷ 1.15 = GST-exclusive amount

These formulas provide accurate results for any transaction.

Who Must Register for GST in New Zealand?

You must register for GST in New Zealand if your taxable supplies exceed NZD $60,000 in any 12 months or if you expect they will exceed that threshold. This includes situations where future contracts or business growth clearly indicate that your turnover will surpass the requirement.

Voluntary registration is also allowed for smaller businesses, but keep in mind that once registered, you must charge GST on your sales, issue GST invoices, and file GST returns.

If you advertise GST-inclusive prices or claim GST on your business purchases, you must be registered. Operating while unregistered but charging GST is a breach of IRD rules.

Zero-rated, Exempt, and Special Supplies

Not all supplies in New Zealand are taxed in the same way. GST is divided into three main categories: standard-rated, zero-rated, and exempt supplies.

Standard-rated supplies, charged at 15%, apply to most goods and services sold within New Zealand. This includes things like buying things at a store, getting services at a hotel, doing trades, running a business, buying digital items, and many other common transactions. Companies have to charge GST on these goods and can get GST credits for costs that are related to them.

Zero-rated supplies are taxed at a rate of 0%. While businesses must record these transactions, they do not charge GST to their customers. Examples of zero-rated supply include exports of goods, certain services given to overseas consumers, sales of a going company that meet IRD rules, and some land transactions. These rules ensure that GST is not applied to consumption outside New Zealand.

Exempt supplies are transactions where no GST is levied, and firms cannot receive GST credits on connected expenses. Some common exempt supplies are rental income from homes, financial services like interest and some fees, and goods that non-profits give away and sell.

Frequently Asked Questions (FAQ)

What is the current GST rate in New Zealand?

The current Goods and Services Tax (GST) rate in New Zealand is 15%. This applies to most goods and services sold in the country, including retail products, professional services, and imported items. GST is a consumption tax, meaning it is ultimately paid by the end consumer, while registered businesses collect and remit it to the Inland Revenue Department (IRD).

Calculating GST for your business involves determining whether you need to add GST, remove it, or extract it from an inclusive total. A GST calculator simplifies this process.

  • Adding GST: Multiply the GST-exclusive amount by 1.15 to get the GST-inclusive price.

  • Removing GST: Divide the GST-inclusive amount by 1.15 to get the GST-exclusive price.

  • Extracting GST: Multiply the GST-inclusive amount by 3 and divide by 23 to calculate the GST portion.

Businesses should regularly calculate GST on invoices, purchases, and sales to maintain accurate financial records. Additionally, keeping detailed transaction logs ensures compliance during GST return submissions to the IRD.

Yes, certain goods and services are GST-exempt, meaning GST is not charged on them. Common exemptions include:

  • Financial services, like interest on loans and certain insurance policies.

  • Residential rent for private housing.

  • Donations to registered charities.

  • Certain educational services and government fees.

Understanding these exemptions is crucial for accurate invoicing and GST reporting. Charging GST on exempt items or failing to charge GST on taxable items can lead to errors and potential penalties from the IRD.

In New Zealand, GST is usually 15%. To calculate, multiply the net price by 15%. For instance, if your item costs NZ$200, GST is NZ$200 × 15% = NZ$30. The total including GST is NZ$230. You can also divide a GST-inclusive price by 1.15 to find the price before GST.

To find the GST component from a total price that already includes GST, divide the total by 1 plus the GST rate. For example, if a total price is $115 and GST is 15%, GST = $115 ÷ 1.15 × 0.15 ≈ $15. This separates the tax from the total.

The GST component refers to the amount of tax included in a price. If you know the total price, divide by 1 plus the GST rate to get the net price, then subtract it from the total. Example: Total = $115, GST rate = 15% → $115 ÷ 1.15 ≈ $100 net, GST component = $115 − $100 = $15.
