## What is GST in New Zealand?

New Zealand charges 15% GST on most goods and services, with exports zero-rated and residential rent exempt under Inland Revenue rules.

### Forward and reverse formulas

When you already know the price *excluding* tax:

When you only have the tax-inclusive price, work backward instead:

### Example at 15%

Say the price excluding GST is **NZ$1,000**. The tax comes to **NZ$150.00**, which puts the price including tax at **NZ$1,150.00**.

### New Zealand tax reference

Confirm current New Zealand rates, exemptions, and filing rules with the [Inland Revenue New Zealand](https://www.ird.govt.nz) before lodging returns. This calculator uses headline standard rates for estimation only.

### GST vs sales tax vs VAT

**Goods and services tax (GST)** and **value-added tax (VAT)** are both multi-stage consumption taxes that give registered businesses an input-tax credit along the way. **Sales tax**, more common in the United States, usually gets charged just once at retail. This calculator sticks to single-rate GST/VAT math, so double-check exemptions and filing rules with your local revenue authority before relying on it for anything official.

## Frequently Asked Questions

### How do I remove GST from a tax-inclusive price?
Enter the **price including GST** and pick the rate. The calculator divides by (1 + rate) to pull out the pre-tax amount and shows the tax portion on its own line.

### What rate does the NZ GST Calculator use?
It defaults to **15%** for New Zealand.

### Can I enter the GST amount instead of the full price?
Sure. Type in the **GST amount** plus either the inclusive or exclusive price, and the tool fills in whatever is missing based on the selected rate.

### Is this calculator official for New Zealand?
No, treat it as an **estimation tool** for shopping, invoicing, and learning the math. Confirm actual rates, exemptions, and rounding rules with your revenue authority before you file anything.
