Adjusting GST

You may need to make adjustments that change the amount of GST you're liable to pay.

You may have an adjustment if one of the following occurs:

• the price of a sale or a purchase changed - for example, you provide a discount to a customer or receive a rebate from a seller
• a taxable sale you made, or a purchase you're entitled to a GST credit for, is cancelled (for example, where goods are returned)
• you write off a bad debt or you recover a previously written-off bad debt
• your actual use of a purchase or importation for business purposes differs from your intended use.

There are also other circumstances where you may be required to make an adjustment, such as when you:

• cease registration
• sell something you used for making financial supplies.
