About GST in New Zealand
Goods and Services Tax (GST) is a value-added tax of 15% applied to most goods and services in New Zealand. Businesses, freelancers, and consumers often need to calculate GST either by adding it to a GST-exclusive price or removing it from a GST-inclusive amount. For business expenses, only the business-use portion of GST can be claimed. This calculator helps you quickly determine GST amounts, GST-exclusive or inclusive totals, and the claimable GST for business use, all in line with New Zealand’s tax rules.

How to Use the GST Calculator NZ
Step One: Enter the amount you want to calculate GST for. This can be either a GST-exclusive or GST-inclusive amount, depending on whether you want to add or remove GST.
Step Two: Select the calculation type. Choose “Add GST” if your amount is GST-exclusive and you want to find the total including GST. Choose “Remove GST” if your amount already includes GST and you want to find the GST-exclusive value.
Step Three: Adjust the GST rate if needed. The default rate is 15%, which is the standard in New Zealand, but you can change it for special scenarios.
Step Four: If your expense is partly for business and partly for personal use, enter the business use percentage. This helps determine how much GST you can claim for business purposes.
Step Five: Click “Calculate GST” to instantly see the GST amount, the GST-inclusive or exclusive total, and a clear explanation of how the result was calculated. If you entered a business use percentage, the calculator will also show the claimable GST for your business records.
