ABN Registration — Register Your Australian Business Number

An ABN (Australian Business Number) is a free 11-digit number from the ATO that identifies your business. You need one to work as a sole trader, contractor, or rideshare driver, to invoice clients, and to register for GST. ALITAX, a registered tax agent (No. 25287564), prepares and lodges your ABN application with the Australian Business Register — usually within 1–2 business days.

Fast ABN Registration by a Registered Tax Agent

ALITAX registers your ABN (Australian Business Number) with the ATO on your behalf. Our registered tax agent handles all the paperwork so your ABN is issued quickly — typically within 1–2 business days of submission.

Who Needs an ABN?

• Sole traders starting a business or freelance work
• Rideshare and delivery drivers (Uber, Didi, DoorDash, Uber Eats)
• Contractors and self-employed individuals
• Anyone carrying on an enterprise in Australia

What You Need to Apply

• Your TFN (Tax File Number)
• Personal details: name, date of birth, address
• Your occupation or business description
• Preferred ABN start date

Optional: Register for GST at the Same Time

If you expect your annual turnover to exceed $75,000 — or if you are a rideshare driver — you can register for GST at the same time as your ABN. ALITAX will handle both registrations together.
