Getting an ABN and Business Basics for Australian VAs

The VA Handbook · Updated 2026-07-18

Before you send your first invoice as a virtual assistant, a small amount of business housekeeping saves a large amount of later pain. The centrepiece is the ABN.

What an ABN is and why you need one

An Australian Business Number is a unique identifier for your business used on invoices, in dealings with the Australian Taxation Office, and when registering for other services. Clients will expect an ABN on your invoices; without one, other businesses may be required to withhold tax from payments to you at the highest rate — a rule described on the ATO website. Applying is free through the Australian Business Register, and business.gov.au walks through the process and eligibility questions. Be wary of third-party websites that charge a fee to lodge the free application on your behalf.

When you apply you will confirm that you are carrying on an enterprise — which, as a VA offering services to clients for payment, you are. Most VAs start as sole traders: the simplest structure, where you and the business are legally the same entity and business income is reported in your personal tax return. Companies and trusts exist as alternatives with different costs and protections; business.gov.au compares the structures if your circumstances warrant a look.

Business name, or your own?

Trading under your personal name requires no registration. If you want a distinct brand — say, a name that signals your niche — you register the business name with ASIC for a periodic fee, after checking the name is available. A registered business name is not a trademark; it simply lets you legally trade under that name. Many successful VAs never register a name at all, and clients do not care either way. Decide based on how you want to market yourself, not on a sense of obligation.

The unglamorous foundations

Three habits set up in week one will serve you for years. First, a separate bank account for business income and expenses, so your records reconcile cleanly. Second, a record-keeping system — even a simple spreadsheet or entry-level accounting software — capturing every invoice issued and expense incurred, because the ATO requires business records to be kept and you will need them at tax time. Third, a basic terms document you attach to engagements, covering scope, rates, payment terms and confidentiality, so every client relationship starts with the same clear footing.

None of this takes more than a few hours, and all of it signals to prospective clients that you run a real business rather than a hobby. That impression matters most at the exact moment you have the least track record.

One last habit worth adopting from day one: keep a single folder — digital is fine — holding your ABN confirmation, any business name certificate, insurance documents, your terms template and copies of signed agreements. Prospective clients, insurers, banks and eventually your accountant will each ask for pieces of this paperwork at unpredictable moments, and producing the right document in two minutes rather than two days is one of those small, repeated moments that builds a reputation for having your act together.

FAQ

Does registering an ABN cost anything?

No. Applying through the official Australian Business Register is free. Third-party services that charge for lodgement are optional middlemen, not a requirement.

Do I need to register a company?

Not to start. Most Australian VAs operate as sole traders. A company structure brings extra cost and administration, and suits some situations later — business.gov.au and professional advice can guide that decision when turnover and risk justify it.
