Can I Invoice Without an ABN?

Yes, you can issue an invoice without an ABN, but if you're carrying on an enterprise in Australia and the invoice is over $75 (excluding GST), the client is required to withhold 47% of the payment under the No-ABN Withholding rule. So practically — if you're regularly invoicing for business activity, you need an ABN.

Without an ABN:

Clients must withhold 47% and remit it to the ATO
You'll find it harder to claim business deductions or register for GST later
Some clients won't engage you at all because of the admin burden

You can avoid the 47% withholding without an ABN by:

Submitting a "Statement by a Supplier" form, declaring the payment is genuinely a private or hobby transaction
Selling a one-off personal item that isn't part of a business

Applying for an ABN is free at abr.gov.au and usually takes under five minutes. Once you have it, display it on every invoice in the format "ABN: XX XXX XXX XXX". InvoiceSonic stores your ABN once and adds it to every invoice automatically.
