How Much Is GST in NZ? A Simple Guide to 15% GST

Quick Answer: How Much Is GST in NZ?

The standard GST rate in New Zealand is 15%. GST is a consumption tax charged on most goods and services supplied in New Zealand.

If you have a GST-exclusive price, you can calculate the GST by multiplying the price by 15%.

For example:

• $100 + GST = $115
• $500 + GST = $575
• $1,000 + GST = $1,150

If a price already includes GST, you do not simply subtract 15%. To calculate the GST component of a GST-inclusive amount, multiply the total by 3 ÷ 23.

For example, if the total price is $115 including GST, the GST component is $15 and the GST-exclusive price is $100.

The standard GST rate of 15% is confirmed by Inland Revenue. View the official Inland Revenue GST guidance.

What Is GST in New Zealand?

GST stands for Goods and Services Tax. It is a consumption tax applied to most goods and services supplied in New Zealand.

GST is generally charged by GST-registered businesses and other registered entities on taxable supplies. The standard GST rate is 15%.

For a GST-registered business, GST collected from customers is generally accounted for to Inland Revenue through GST returns. The business may also be able to claim eligible GST on business purchases and expenses.

This means GST is an important part of both business pricing and cash-flow management. Businesses need to understand whether their prices include GST and how much GST they may need to pay to Inland Revenue.

For more information, see our guide to GST Calculator NZ .

What Is the GST Rate in NZ?

The standard GST rate in NZ is 15%.

This means that if a GST-registered business sells a taxable good or service for $100 before GST, the standard GST amount is $15 and the GST-inclusive price is $115.

However, not every transaction is necessarily treated in the same way. Some supplies can be zero-rated, exempt or subject to specific GST rules.

Businesses should therefore check the GST treatment of a particular transaction rather than assuming that every sale attracts GST at 15%.

How Do You Calculate GST in NZ?

There are two common GST calculations: adding GST to a GST-exclusive amount and working out the GST component of a GST-inclusive amount.

How to Add GST to a Price

To calculate 15% GST on an amount that does not include GST:

GST = GST-exclusive price × 15%

Then:

GST-inclusive price = GST-exclusive price + GST

Example: $100 Before GST

$100 × 15% = $15 GST

$100 + $15 = $115 including GST

Example: $500 Before GST

$500 × 15% = $75 GST

$500 + $75 = $575 including GST

Example: $1,000 Before GST

$1,000 × 15% = $150 GST

$1,000 + $150 = $1,150 including GST

For detailed GST calculation guidance, see Inland Revenue’s GST calculation guidance .

How Do You Remove GST From a Price in NZ?

If you have a GST-inclusive amount and want to find the GST-exclusive amount, you should not simply subtract 15%.

The GST component of a GST-inclusive amount can be calculated using:

GST = GST-inclusive amount × 3 ÷ 23

Then:

GST-exclusive amount = GST-inclusive amount − GST

Example: Removing GST From $115

$115 × 3 ÷ 23 = $15 GST

$115 − $15 = $100 excluding GST

Example: Removing GST From $575

$575 × 3 ÷ 23 = $75 GST

$575 − $75 = $500 excluding GST

Example: Removing GST From $1,150

$1,150 × 3 ÷ 23 = $150 GST

$1,150 − $150 = $1,000 excluding GST

GST Calculation Examples in NZ

These examples assume the standard 15% GST rate applies and that the starting amount is GST-exclusive.

What Does GST Inclusive Mean?

A GST-inclusive price already contains GST.

For example, if a product is advertised at $115 including GST, the customer pays $115. The GST component is $15 and the GST-exclusive amount is $100.

Businesses should be clear about whether prices are GST-inclusive or GST-exclusive when quoting customers, preparing invoices or publishing prices online.

This is particularly important when comparing supplier prices or calculating expected business margins.

What Does GST Exclusive Mean?

A GST-exclusive price does not include GST.

For example, if a business quotes $1,000 plus GST, the GST is:

$1,000 × 15% = $150

The customer would therefore pay:

$1,150 including GST

Businesses should make their pricing clear so customers understand whether the quoted amount includes GST.

When Does a Business Need to Register for GST in NZ?

Not every business automatically has to register for GST when it starts trading.

According to Inland Revenue, you generally need to register for GST if you carry out a taxable activity and:

• Your taxable turnover was at least $60,000 in the last 12 months; or
• You expect your taxable turnover to be at least $60,000 in the next 12 months; or
• You carry out a taxable activity and add GST to your prices.

Businesses with turnover below $60,000 can also choose to register voluntarily in some circumstances.

If you are unsure whether your business needs to register for GST, it is worth getting professional advice before adding GST to your prices.

You can read more about GST registration on the Inland Revenue website .

What Are Your Responsibilities After GST Registration?

Once a business is registered for GST, there are ongoing compliance responsibilities.

These generally include:

• Charging GST on taxable supplies where required.
• Filing GST returns.
• Paying GST owed to Inland Revenue.
• Keeping appropriate GST records.
• Claiming eligible GST on business purchases and expenses.
• Keeping supporting information for GST transactions.

Good GST record-keeping is important because accurate records help businesses prepare returns and support the amounts reported to Inland Revenue.

How Does GST Work When You File a GST Return?

GST-registered businesses generally account for GST through regular GST returns.

The calculation is not simply the total GST charged to customers. You also need to consider eligible GST on purchases and expenses, along with applicable adjustments and the accounting basis used by the business.

If you collected more GST than you can claim for the relevant period, you generally pay the difference to Inland Revenue. If you paid more eligible GST than you collected, you may be entitled to a refund.

This is why understanding your GST position is important when managing business cash flow.

When Is a GST Return Due in NZ?

GST return due dates depend on the taxable period selected by the business.

For many taxable periods, Inland Revenue states that the GST return and payment are due by the 28th of the month following the end of the taxable period.

There are exceptions for taxable periods ending 31 March and 30 November.

For example, a taxable period ending 31 May normally has a GST return and payment due on 28 June.

GST-registered businesses should check their specific taxable period and due dates rather than relying on a general date.

See Inland Revenue’s GST filing guidance for current requirements.

Common GST Calculation Mistakes in NZ

Calculating GST is straightforward when the correct starting amount and GST treatment are known. However, businesses can make mistakes when preparing invoices, quotes or GST returns.

1. Adding 15% to a GST-Inclusive Price

If a price already includes GST, adding another 15% will overstate the amount.

2. Subtracting 15% From a GST-Inclusive Amount

To remove GST correctly from a GST-inclusive amount, use the 3 ÷ 23 calculation rather than simply subtracting 15%.

3. Assuming Every Transaction Has 15% GST

Some supplies have different GST treatment, including zero-rated and exempt supplies. Always check the applicable rules for the transaction.

4. Forgetting GST on Business Expenses

Eligible GST on business purchases may be claimable, subject to the relevant rules and supporting records.

5. Mixing GST-Inclusive and GST-Exclusive Figures

Keeping clear records of whether figures include GST can help reduce errors when preparing accounts and GST returns.

GST for Small Businesses and Sole Traders

GST can have a significant impact on pricing and cash flow for small businesses, sole traders and contractors.

If your business becomes GST registered, you generally need to account for GST on taxable sales, file GST returns and keep appropriate records.

This means GST should be considered when setting prices, preparing quotes and forecasting cash flow.

For example, if you quote a customer $10,000 plus GST, the invoice total at the standard rate would be $11,500. The additional $1,500 is GST collected rather than ordinary business revenue.

Understanding this distinction can help business owners avoid spending money that may later need to be paid to Inland Revenue.

How Does GST Affect Business Cash Flow?

GST can create cash-flow pressure when businesses collect GST from customers but do not set aside enough funds for their GST liability.

A business may receive a customer payment that includes GST, but the GST component is generally not business profit.

For example, if a customer pays $11,500 including GST, $1,500 represents GST at the standard 15% rate and the GST-exclusive amount is $10,000.

Businesses should therefore consider upcoming GST payments when preparing cash-flow forecasts.
