Online GST (and provisional tax) return (GST101/GST103)
The following information supports the online GST return. You can find this and all our other interactive forms at "Get it done online", "Work it out" and "Forms and guides".
Panel 1 - GST registration number and DLN number
When you send your GST return to us, we use the GST registration number, DLN number and period end date to:
- allow the return to be passed directly into our computer system
- help confirm that the person sending the return is authorised to do so.
If any of this information doesn't match with our records there will be a delay in processing the return and sending the assessment or refund. We may need to phone you to ask which business and period the return was intended for.
To get the best possible service please use the DLN number printed at the top of the paper return for the GST return you are filing online. The DLN is a 14 character number - all the characters are numerals except the second to last which is a capital letter. If you don't have the DLN number, call us on 0800 377 776 and we can help.
Choosing a method to complete your return
Depending on your accounting system, you may know either:
- your total sales/income and purchases/expenses, or
- the GST content of your total sales/income and purchases/expenses.
If you choose the first option (knowing your sales/income or purchases/expenses) the GST content of these amounts will be worked out for you when you complete the return.
If you choose the second option (knowing your GST on sales/income or GST on purchases/expenses) the total sales/income or purchases/expenses will be worked out for you when you complete the return. This option is particularly useful if you use the payments basis of accounting and you complete a cashbook with a GST column.
Panel 3a - Address change
If your address is different to the preprinted address on the paper return you received from us, you'll need to change it here so we can make sure we send your returns to the correct address in the future.
If your address is a PO Box number, please show your box lobby (this is the location of your post office box, such as "Wellington Mail Centre" or "Shortland Street"). If you are unsure what your box lobby is or whether you have one, please contact NZ Post on 0800 501 501.

Ratio option for provisional tax:
If you've elected to use the ratio option to calculate your provisional tax, you can calculate your provisional tax instalment using this online service. Please refer to the GST and provisional tax return (GST103) that we send you to see which boxes you need fill in.
For more information about the ratio option, the eligibility criteria how it works and provisional tax in general, please see our Provisional tax guide (IR289).
Transfer GST sales from page 1 - Box 16
To work out your provisional tax instalment using the ratio option, transfer your total sales and income that you entered into Box 5 to Box 16.
One-monthly GST filers - Box 17
Using the ratio option, you need to make six provisional tax instalments each year. As you file GST every month, this means you need to pay previsional tax with every second GST and provisional tax return (GST103).
You can calculate your provisional tax instalment using this online service. The GST and provisional tax return (GST103) we send you will show you if a compulsory provisional tax instalment is due or not.
If there's a compulsory provisional tax instalment due, you need to include last month's sales in Box 17. Please check your records for last month's GST sales.
It's important to file your GST and provisional tax using this service or by post on your GST and provisional tax return (GST103) by the due date each month.
More than one GST registration - Box 19
If you have more than one branch/company which file GST returns every month you need to include the GST sales for the other branch(es)/company(ies) from this month's and last month's GST and provisional tax returns.
Disposal of an asset - Box 21
If you've sold an asset, you can make an adjustment for the asset's worth. This will reduce the amount of total GST taxable supplies by the amount of the asset sale for the purpose of calculating your provisional tax.
The criteria for making an asset adjustment are:
- The asset is not revenue account property.
- The value of asset is the greater of:
- an amount equal to 5% of the total taxable supplies in the last 12 months, or
- $1,000.
For customers using the payment basis, the amount claimable is limited to the amount that must be declared as an income over the two-month period for the asset.
Where do I find my ratio percentage?
Your ratio percentage will be sent to you by letter and also pre-printed on your GST and provisional tax return (GST103).
How do I calculate my provisional tax instalment? (Box 23)
Follow steps 16 to 22. Multiply the amount in Box 22 by your ratio percentage and put the answer in Box 23.
Please remember - these returns are tailored to your circumstances. Some boxes won't show on your personal return because you don't need to complete them.
Voluntary periods - Box 24
If your GST and provisional tax return shows a voluntary payment period for provisional tax, you have the opportunity to make a voluntary provisional tax payment. This will help to reduce your income tax owing at the end of the year.
It's important to remember any voluntary payments you've made, when you calculate your compulsory provisional tax instalments.
If the GST and provisional tax return we send you in the post shows a voluntary payment period, and you wish to make a voluntary payment then please put this in Box 24.
Transferring GST refunds to provisional tax - Box 25
If you've worked out that you'll receive a refund in Box 15, you can choose to transfer some or all of this credit to your provisional tax. Enter the amount you'd like to transfer to your provisional tax in Box 25.
Combined GST and provisional tax payments - Box 27 and Box 28
If you have GST to pay in Box 15 put this figure in Box 27. Add Box 26 and Box 27. The total GST and provisional tax payment due is shown in Box 28.
