Small business’ contribution to Australian business numbers is one indicator of their contribution to the Australian economy. This can be explored by looking at the number of small businesses by employment and turnover.

Number of small businesses by employment

The Australian Bureau of Statistics (ABS) defines small businesses as those with less than 20 employees. As shown in Table 1, 97.3% of all Australian businesses were small businesses in June 2025.

As shown above in Table 2, over half (64%) of Australian businesses are self-employed/non-employing. An additional 25% of businesses employed 1-4 people and 9% employed 5-19 people. These businesses are all classified as a small business according to the ABS definition based on employment size.

As shown in the chart above, the number of self-employed businesses with no additional employees and large businesses with at least two hundred employees increased in 2024-25 by 4.3% and 2.6% respectively. The number of businesses in all other employment ranges fell in 2024-25.

These ABS statistics report businesses that are actively remitting Goods and Services Tax (GST). There were 2,729,648 businesses (active Australian Business Numbers (ABNS)) in scope in 2024-25. There were an additional 6,009,760 ABNs that were not actively remitting GST.


Number of small businesses by turnover

A common definition of small business used by the Australian Taxation Office (ATO) are those businesses with a turnover of less than $10 million.

Using this definition, 98% of Australian businesses are small businesses. The vast majority (92%) of these businesses have a turnover of less than $2 million. However, it is likely that this figure underestimates businesses with a turnover below $75,000 as it is based on businesses registered for GST. Businesses only need to register for GST if their current or projected turnover is $75,000 or more.
