Great question—and one we hear often from multi-talented business owners.
According to the Australian Business Register (ABR), you can use the same ABN for more than one business activity, as long as they all operate under the same business structure.
So, if both your calligraphy and virtual assistant businesses are set up as a sole trader under your name, you don’t need a second ABN.
But there are two important things to keep in mind:
- If the new business has a different structure (e.g. you’re setting up your VA business as a company or partnership), then yes, you’ll need to register a new ABN.
- You must update your ABN details to include any new business activities. The ATO requires you to do this within 28 days of the change. You can update your information using ABR online services.
What’s helpful is that you can now include up to four additional business activities when updating your ABN. So you don’t need a new number for every new idea—you just need to keep your records accurate.

Key Takeaways
- Same Structure: If both businesses operate under the same structure (e.g., sole trader), you can use the same ABN.
- Different Structures: If the new business has a different structure, you’ll need a separate ABN.
- Update Details: Always update your ABN details to reflect new business activities within 28 days.
