How to Remove GST from Price NZ
If you’ve ever looked at a receipt in New Zealand and wondered what the actual price was before tax, you’re not alone. Whether you’re a small business owner reconciling accounts or simply curious about how much GST you’re paying, understanding how to remove GST from a price is surprisingly useful.
Understanding New Zealand’s GST
New Zealand’s Goods and Services Tax sits at 15% and is typically built into the prices you see on store shelves and menus. Unlike some countries where tax is added at checkout, Kiwi shoppers see the final price upfront – which is convenient but makes it trickier to work backwards. If you’re new to GST, check out our guide on what is GST in NZ for a comprehensive overview.
The Simple Formula
Removing GST isn’t as straightforward as just subtracting 15%. Since GST is calculated on top of the base price, you need to divide by 1.15 to find the original amount:
Price excluding GST = Price including GST ÷ 1.15
Real-World Examples
Example 1: Coffee Machine You purchase a coffee machine for $345 (GST-inclusive). To find the base price:
- $345 ÷ 1.15 = $300 (price before GST)
- GST amount: $345 – $300 = $45
Example 2: Consulting Services An invoice shows $1,150 for professional services. Breaking it down:
- $1,150 ÷ 1.15 = $1,000 (base fee)
- GST component: $150
Example 3: Retail Purchase That $92 shirt you bought actually breaks down to:
- $92 ÷ 1.15 = $80 (pre-GST price)
- Tax paid: $12
Quick Tips for Business Owners
If you’re GST-registered, keeping track of these calculations is essential for filing your returns. Many accounting software programs do this automatically, but knowing the manual method helps verify numbers and catch errors.

You can also quickly calculate just the GST portion by multiplying the GST-exclusive price by 0.15. For instance, on a $200 base price: $200 × 0.15 = $30 GST.
