Goods and Services Tax (GST) is a tax of 10% in Australia on most goods, services, and other consumables. If you are a registered business, you need to charge GST on most goods and services you sell or supply. You must be a registered if your business turnover exceeds $75,000 per annum or $150,000 for a not-for-profit organization but you may elect for voluntary registration if you are below the threshold.
Likewise registered suppliers will include GST in the price of items you purchase from them for your business. You may be entitled to claim input tax credits from the ATO if you are registered for GST and the acquisitions are acquired for the purpose of carrying on your enterprise. Although the liability for paying GST rests with GST-registered entities, the end consumer bears the economic cost.
Some supplies will be GST free such as medical and educational services but you are still entitled to claim input tax credits for GST included in any purchases you made if you are a registered entity. For an input tax sale, such as providing residential rental accommodation, you do not charge GST on the sale of the goods or services to your customers and cannot claim input tax credits for the GST portion of your business expenses relating to the items acquired to make the supply.
The reporting periods for GST are called tax periods and can be quarterly or monthly. Quarterly tax periods are three months long, ending 30 September, 31 December, 31 March, and 30 June. Monthly tax periods end on the last day of each calendar month. Entities with an annual turnover of less than $20 million generally have quarterly tax periods, but can choose to have monthly tax periods. Entities with an annual turnover greater than $20 million are required to have monthly tax periods.
The rules for attributing GST payable and input tax credits to tax periods differ according to whether GST is accounted for on a cash or accrual basis. You can account for GST on a cash basis if you meet one of these requirements:
If you are not registered for GST, you cannot include GST on anything you sell or provide. You also cannot claim back any GST included in the price you pay for goods or services used in your business.
