Choosing GST instalments and changing your choice
To elect to pay by GST instalments you must contact us by phone on 13 28 66. If you are eligible, we will change your reporting method to instalments.
If you contact us by 28 October, your choice will take effect from 1 July of that financial year – that is, from the beginning of the September quarter. You then pay by instalments for the entire financial year.
From 1 July 2017, your GST instalment election is generally automatically rolled over at the end of the financial year, based on your turnover.
If you want to change to another reporting method, you may have to wait until the next financial year.
If you contact us by 28 October, your election or revocation of GST instalments will generally take effect from 1 July of that financial year (or by the concessional due date, if you lodge your September quarter activity statement through a registered agent).
If you contact us after 28 October, your election or revocation of GST instalments will generally take effect from 1 July of the next financial year.
You may request in writing that your election or revocation take effect from the start of an earlier tax period. However, we will only approve your request if there are exceptional circumstances.
If you first become eligible for instalments after 28 October and you have been lodging BAS for six months or less, you can make your election after 28 October. But it must be made by the date on which you have to lodge your next BAS after you first became eligible.
To continue to be eligible for GST instalments, make sure you keep your lodgments up-to-date.
You shouldn't choose the GST instalments reporting method if you think you'll be in a net refund position – that is, if your total GST credits for the year will be more than the total GST you're liable to pay. With the instalments reporting method we only pay refunds after you lodge your annual GST return, not each quarter.
