What Is GST in New Zealand?

Goods and Services Tax (GST) is a value-added tax charged on most goods and services supplied in New Zealand. The current standard GST rate is 15%. Businesses registered for GST collect GST from customers and pay it to Inland Revenue after deducting eligible GST expenses.

The GST Calculator New Zealand helps businesses, freelancers, contractors, landlords, accountants, and consumers quickly calculate GST without performing manual calculations.


GST Calculation Formulas

Add GST (Exclusive → Inclusive)

Formula:

GST = Amount × 15%

GST Inclusive = Amount + GST

Example:

$100 + 15% GST = $115.00


Remove GST (Inclusive → Exclusive)

Formula:

GST Exclusive = GST Inclusive ÷ 1.15

GST Amount = GST Inclusive − GST Exclusive

Example:

$115 ÷ 1.15 = $100.00


GST Calculation Examples

GST Exclusive GST GST Inclusive
$50.00 $7.50 $57.50
$100.00 $15.00 $115.00
$250.00 $37.50 $287.50
