Comprehensive Guide to GST in New Zealand (2024)
Goods and Services Tax (GST) is a broad-based consumption tax applied to most goods and services in New Zealand. Introduced in 1986 at a rate of 10%, the standard GST rate increased to 12.5% in 1989 and then to its current rate of 15% in 2010. This guide provides everything you need to know about calculating GST in New Zealand, including how it works, what’s taxable, and how to manage your GST obligations.
How GST Works in New Zealand
GST is a value-added tax that applies to:
- Most goods and services sold in New Zealand
- Imports into New Zealand
- Certain services provided from overseas to New Zealand residents
The current standard GST rate is 15%, though some items qualify for reduced rates or exemptions:
| Category | GST Rate | Examples |
|---|---|---|
| Standard Rate | 15% | Most goods and services, electronics, clothing, professional services |
| Reduced Rate | 9% | Certain accommodation services (until 31 March 2025) |
| Zero-rated | 0% | Exported goods, international services, financial services |
| Exempt | N/A | Residential rent, salary/wages, interest on loans |
When to Register for GST
Businesses must register for GST when:
- Your taxable activity’s turnover exceeds (or is expected to exceed) $60,000 in any 12-month period
- You provide taxi or ride-sharing services (regardless of turnover)
- You want to claim GST on business expenses (voluntary registration)
Once registered, you must:
- Charge GST on your sales (output tax)
- Keep records of all transactions
- File GST returns (usually every 1, 2, or 6 months)
- Pay the difference between GST collected and GST paid to Inland Revenue
How to Calculate GST in New Zealand
Calculating GST depends on whether you’re adding it to a price (for sales) or removing it (for purchases). Here are the formulas:
Adding GST to a Price
When you need to calculate the total price including GST:
Total Price = Original Price × (1 + GST Rate)
Example: For a $100 product with 15% GST:
$100 × 1.15 = $115 total price
Removing GST from a Price
When you need to find the pre-GST price from a total that includes GST:
Original Price = Total Price ÷ (1 + GST Rate)
Example: For a $115 total price with 15% GST:
$115 ÷ 1.15 = $100 original price
GST Return Filing Frequencies
Businesses can choose their GST return filing frequency, though Inland Revenue may set this for new registrants:
| Frequency | Due Date | Payment Due | Best For |
|---|---|---|---|
| Monthly | 28th of the following month | Same as return due date | Businesses with high turnover or cash flow benefits |
| 2-monthly | 28th of the month following the end of the period | Same as return due date | Most common choice for small businesses |
| 6-monthly | 28th of the month following the end of the period | Same as return due date | Businesses with low turnover (under $500,000 annually) |
Common GST Mistakes to Avoid
Avoid these frequent GST errors that can lead to penalties:
- Not registering on time: Failing to register when your turnover exceeds $60,000 can result in backdated GST payments plus penalties.
- Incorrect claims: Claiming GST on expenses that don’t qualify (e.g., private expenses, entertainment).
- Late filings: Missing GST return deadlines incurs late filing penalties (currently $50 for the first late return, $250 for subsequent late returns).
- Wrong GST rate: Applying the incorrect rate to supplies (e.g., using 15% when 0% applies to exports).
- Poor record-keeping: Inland Revenue requires records to be kept for 7 years.
GST for Specific Industries
Property Transactions
GST applies to most property sales in New Zealand, but there are special rules:
- Sale of a residential property is generally exempt from GST unless sold by a registered person in the course of their taxable activity.
- Sale of commercial property is usually subject to GST at 15%.
- The “going concern” exemption may apply when selling a business that includes property.
E-commerce and Digital Services
Since 1 December 2019, overseas businesses selling digital services to New Zealand consumers must:
- Register for GST if their sales exceed NZ$60,000 per year
- Charge GST at 15% on digital services (e.g., streaming, apps, e-books)
- File GST returns (simplified process available for non-resident suppliers)
