Do I Need an ABN? Here's How to Actually Know

You've made a few sales on Etsy. Or someone's asked you to invoice them for a job you did on the side. And now you're sitting there wondering, am I actually running a business, or am I just messing around and about to get myself in trouble?

That question stops more people than it should. Not because the answer is complicated, but because nobody ever actually explains it properly, so people either avoid the whole thing out of nerves, or assume they're fine and find out the hard way that they weren't.

Here's the honest answer.

Hobby or business? It comes down to a few things, not a feeling

The ATO doesn't care what you call it. It looks at whether you're actually running an enterprise, are you doing it repeatedly and regularly, are you doing it to make a profit, is it run in a commercial way, is it growing in size and scale. Tick enough of those boxes and it's a business, whatever you've been calling it in your head.

It's not about how much you're earning

This is the one that trips people up most. There's no income threshold that triggers needing an ABN. People wait until they hit some number in their head, often confusing it with the $75,000 GST turnover threshold, which is a completely separate thing. The real trigger is whether you're carrying on an enterprise, not what you've made from it so far.

What actually happens if you skip it

Not having an ABN isn't illegal. But if you invoice a business more than $75 and you haven't quoted an ABN, they're required to withhold 47% of that payment and send it to the ATO instead of you. Most people find this out the way you'd expect, badly, when a payment lands in their account for less than half of what they invoiced, with no warning it was coming.

Getting it right without overthinking it

If what you're doing is genuinely a hobby, you don't need one, and you shouldn't be made to feel like you do. But the moment it looks and acts like a business, regular, intentional, growing, it's worth getting sorted properly rather than hoping nobody notices.

If you're not sure which side of that line you're on, that's a five minute conversation, not something to lose sleep over.
