If your business is registered for GST, you are entitled to claim GST credits for any GST included in the price of goods and services purchased for your business. This is known as an input tax credit. To be eligible, you must intend to use your purchase for your business and the purchase must not relate to making input-taxed supplies.
Additionally, the purchase price must include GST, you must have made or be liable to make payment for the item, and you must hold a tax invoice for purchases over A$82.50. It's important to ensure that your suppliers are registered for GST, which can be verified through the ABN Lookup website.
There is a 4-year time limit for claiming GST credits. If goods or services are used for both business and private purposes, you can only claim a GST credit for the business portion. If your actual use differs from the intended use, you may need to adjust the GST credits claimed. For more detailed information, you can refer to the Australian Taxation Office's guidelines on claiming GST credits.
