  • When you can claim a GST credit

    You must be registered for GST to claim GST credits.

    You can claim a credit for any GST included in the price you pay for things you use in your business. This is called an input tax credit, or a GST credit.

    You claim GST credits in your business activity statement.

    You can claim GST credits if the following conditions apply:

    • You intend to use your purchase solely or partly for your business, and the purchase does not relate to making input-taxed supplies.
    • The purchase price included GST.
    • You provide or are liable to provide payment for the item you purchased.
    • You have a tax invoice from your supplier (for purchases more than A$82.50).

    When claiming GST credits, make sure your suppliers are registered for GST. You can check the GST registration status of an entity by searching the ABN Lookup websiteExternal Link.

    A four-year time limit applies for claiming GST credits.

    GST and purchases for private use

    If you purchase goods or services for both business and private use, you can only claim a GST credit for the part of the purchase relating to your business use.

    If you later find your actual use differed from your intended use, you may need to adjust the amount of GST credits you have claimed.

    If you are a small business, you may be able to account for the private portion of your business purchases once a year, rather than each time you lodge an activity statement. To do this you need to make an annual private apportionment election.

    When you need a tax invoice

    You must have a tax invoice to claim a GST credit for purchases that cost more than A$82.50 (including GST).

    Your supplier has 28 days to provide you with a tax invoice after you request one. Wait until you receive it before you claim the GST credit, even if this is in a later reporting period.

    Tax invoice is incomplete

    An invoice containing incorrect or incomplete information is not a valid tax invoice. You may be able to treat it as a tax invoice if it is missing information that can be obtained from other documents the supplier has given you. Alternatively, you can ask your supplier to replace it with a complete and correct tax invoice. The Commissioner also has the power to treat an incomplete document as a tax invoice.

    When you don't receive a tax invoice

    If your supplier does not respond to your request for a valid tax invoice within the 28 day period and you haven't been able to find the missing information from other documents, you can seek our permission to treat a document as a valid tax invoice. To request our permission, either:

    • email us at
    • write to us at
      Australian Taxation Office
      PO Box 3524
      ALBURY  NSW  2640

    Small purchases

    To claim a GST credit for purchases that cost A$82.50 or less (including GST), you should have one of the following:

    • a tax invoice
    • a cash register docket
    • a receipt
    • an invoice.

    If you can't get one of these, keep a record of the purchase, such as a diary entry with:

    • the name and ABN of the supplier
    • the date of purchase
    • a description of the items purchased
    • the amount paid.

    When you should not be charged GST

    Under new law, GST generally applies to:

    • imported services and digital products
    • low value imported goods (from 1 July 2018).

    You should not be charged GST on these sales if you are registered for GST. You must give the supplier your ABN and state that you are registered for GST.

    The supplier is not required to provide tax invoices for these sales.

    If the supplier has wrongly charged you GST on an imported service, digital product or a low value imported good you should seek a refund from the supplier.

    Reverse charges rules

    If you have not been charged GST on a purchase because you have provided the supplier with your ABN and a statement that you are registered for GST, then, in some circumstances, ‘reverse charge’ rules require you to pay GST on the relevant purchase through your BAS.

    Broadly, under these reverse charge rules, you will need to pay GST on a purchase if you would not have been entitled to claim a full GST credit.

    How to work out a GST credit

    If your tax invoice does not specify the amount of GST included in the price of your purchase by only stating that the price includes GST, you can work out the GST amount yourself by dividing the price by 11. The answer is the amount of GST credit you can claim (provided you use the item wholly for business purposes).

    For purchases that you use both for business and private purposes, you can claim a GST credit for the portion you use for business purposes. For example, if 50% of your use of the purchased item is for business purposes, you can claim a credit of 50% of the GST you paid.

    If you account on a cash basis and have not fully paid for a purchase, you can claim a GST credit only for the GST included in the amount you have paid. (For more information, refer to Choosing an accounting method).

    When you have worked out your total GST credits, you can offset them against the amount of GST you are liable to pay to us. If your GST credits are greater than the amount you are liable to pay, you're entitled to a refund.
