Changing your GST accounting basis

Options for the GST accounting basis are invoice basis, payments basis and hybrids basis. They are explained in detail in Claiming and returning GST.

If we approve your application to change from one GST accounting basis to another, we will write to tell you the date when the changeover begins. We will also send you a calculation of the adjustments you must make for outstanding debtors and creditors. You must record these adjustments in in your GST adjustments calculation sheet (IR372) under "Change in accounting basis" before including these in the corresponding Box (9 or 13) on your GST return.

The table below explains what you need to do after you changed from one GST accounting basis to another.

Note

If you use the payments basis and your turnover goes over the $2 million limit, you must tell us in writing within 21 days. However, you may keep using the payments basis if the increased turnover is caused by either:

  • selling or replacing any plant or asset, or
  • reducing the scale of your taxable activity.

Changing the GST taxable period

You can file your GST return in one-monthly, two-monthly and six-monthly taxable periods. Taxable periods are explained in detail in GST filing frequency.

You may need to change your GST taxable period because of changed turnover, balance date changes, or because you wish to apply for a substantial refund earlier, by adopting a shorter taxable period.

If we approve your application, the change from one taxable period to another is generally effective from the end of the taxable period in which you applied.

Provisional tax and GST

Provisional tax payments are linked to GST taxable periods and your taxable periods must align with your balance date. So if you change your GST taxable period, your provisional tax payments would also change. When you change your GST taxable period you continue on the old cycle until the end of the old taxable period cycle matches up with the beginning of the new cycle.

Example

Your balance date is in March. You file your GST return on a two-monthly basis, ending January, March, May, July, September, and November. You apply during May to change to a six-monthly basis. Although you applied in May you continue to pay GST on a two-monthly basis until the end of September. Then you change to a six-monthly basis from 1 October onwards. For that tax year, you would make two provisional tax payments: on 28 August (on their two-monthly return) and again on 7 May (on their six-monthly return).

Changing the GST group representative

Only the group representative can contact us in writing to change the group representative.

Other changes the group representative can make include:

  • add another member to the group
  • remove a member from the group, or
  • cancel the group status.
