Understanding GST in Australia

What is GST?

Goods and Services Tax (GST) is a 10% tax on most goods, services, and transactions in Australia. If your business has a GST turnover of $75,000 or more ($150,000 for non-profits), you must register for GST.

How GST Works

  • You collect GST from your customers when you make sales (10% of the sale price)
  • You pay GST on your business expenses and purchases
  • On your BAS (Business Activity Statement), you report the difference
  • If you collected more than you paid, you owe the ATO the difference
  • If you paid more than you collected, the ATO refunds you the difference

GST Calculation Formula

If GST is included in the price:

GST Amount = Price ÷ 11

If GST is not included:

GST Amount = Price × 10%

When to Lodge Your BAS

  • Monthly: Due 21 days after month end (for businesses with turnover over $20M or monthly instalments)
  • Quarterly: Due 28 days after quarter end (most common)
  • Annually: Due 28 February (for small businesses)

GST-Free Items

Some items are GST-free, meaning you don't charge GST on them:

  • Most basic food items
  • Health and medical services
  • Education courses
  • Exports
  • Some childcare services
