New Zealand GST Calculator (Goods and Services Tax) 2025

New Zealand charges GST (Goods and Services Tax) at a single flat rate of 15% as of 2025, applied to almost all goods and services. This calculator adds GST to a net price or extracts it from a tax-inclusive (gross) price, instantly and entirely in your browser.

How it works

The calculator works in two modes from the 15% rate:

Add tax — the amount is net, tax = net × 0.15, and gross = net + tax.
Remove tax — the amount is gross (tax-inclusive), so net = gross ÷ 1.15, and the GST is the difference. (Equivalently, the GST portion of a gross price is gross × 3 ÷ 23.)

Example

On a net price of NZ$100:

Field	Value
Net	NZ$100.00
GST (15%)	NZ$15.00
Gross	NZ$115.00

Working backwards from a NZ$115.00 gross price in Remove mode: NZ$115 ÷ 1.15 = NZ$100.00 net, leaving NZ$15.00 of GST.
