What is a GST Return?
If you are a GST-registered business, you’ll need to let the government know how much you’ve collected and how much you’ve paid. You do this by filing a GST return. If you have collected more than you have paid – you will have to pay the difference to IRD. If you have paid more than you have collected – you can get a GST refund from IRD.
Depending on your business size and structure, your GST returns will be due either monthly, two monthly or six monthly and needs to be paid on or before the GST submission date (GST return date).
GST Returns: Payment
If your return says that you owe GST, you’re generally required to make that payment by the day the return is due. You can pay via credit card, debit card, internet banking, or direct debit.
With direct debit, you authorise the IRD to withdraw the GST you owe directly from your business bank account when it’s due. That way you don’t have to worry about missing a deadline.
Interest and fees may be charged on late payments.
Once your business is GST registered, you will be able to deduct GST from legitimate business expenses. Legitimate business expenses are costs required for running your business. You can deduct your business expenses from your income, resulting in less taxable income.
How to calculate GST
GST in New Zealand is 15% for most goods and services. GST rate for exports, and for land that is sold between GST-registered businesses is 0%.
To calculate how much GST should be charged on your selling price multiply the selling price by 0.15.
For example: $300 is the GST exclusive selling price
$300 x 0.15 = $45 $45 is the amount of GST for $300
The price including GST is: $45+$300=$345
To calculate how much GST is included in a price containing GST, multiply the number by 3 then divide it by 23.
For example: $345 is the price containing GST
The amount of GST that was included: $345×3÷23=$45
