Congratulations on Your ABN! 5 Essential Next Steps for 2025

Key Takeaways

• Invoice Correctly: The first step to getting paid is creating a professional and legally compliant tax invoice that includes your ABN.

• Organise Your Finances: Immediately open a separate bank account for your business and choose a bookkeeping system. Good habits start now.

• Manage Your Own Tax: As a business operator, you must set aside a portion of your income to cover your future tax bill. The ATO will not do this for you.

• Keep Your Details Updated: You are legally required to update your ABN details on the Australian Business Register (ABR) within 28 days of any changes.

• Know When to Register for GST: Keep an eye on your turnover. Once it reaches or is likely to reach $75,000 in a 12-month period, you must register for GST.

Introduction

Congratulations! Getting your Australian Business Number (ABN) is an exciting and official first step into the world of being your own boss. You are now officially registered as a business enterprise in Australia. But after the initial confirmation arrives, the big question is: what happens now?

Having an ABN is more than just having a number to put on documents; it comes with new responsibilities. Establishing good habits from day one is the key to running a smooth, compliant, and successful business.

This guide outlines the five essential things you must know and do right after you get your ABN.

To get paid for your work, you need to send an invoice. To ensure it’s professional and meets the ATO’s legal requirements, your invoices must contain specific information.

A compliant invoice must include:

• A statement that it is a “Tax Invoice”.

• Your business name and ABN.

• The date the invoice was issued.

• A brief description of the goods or services provided.

• The total amount payable.

• The words “GST included” if you are registered for GST (if not, you must not mention GST).

• The client’s name or business name.

Creating a simple template with these details will save you time and ensure you always look professional.

This is the most important habit you can build. Do not mix your business and personal finances. Good bookkeeping is not just for tax time; it helps you understand if your business is actually making a profit.

• Open a Separate Bank Account: This is non-negotiable. Have all your business income paid into this account and pay all your business expenses from it. This creates a clean financial record.

• Choose a Record-Keeping Method: This can be a simple spreadsheet for tracking income and expenses, or you can use accounting software like Xero, MYOB, or QuickBooks, which can automate many processes.

• Track Everything: Keep a record of every dollar earned and every dollar spent on the business. Keep digital copies of all receipts for business expenses (e.g., software, materials, fuel, insurance).

When you work for an employer, they withhold tax from your pay. When you work for yourself under an ABN, you are responsible for your own tax.

• Declare All Your Income: The income you earn through your ABN is part of your personal assessable income and must be declared in your annual tax return.

• Set Aside Money for Tax: This is critical. Because no tax is being withheld, you will receive a tax bill at the end of the financial year. A common rule of thumb is to set aside 25-30% of every payment you receive into a separate savings account. This ensures you have the money ready when your tax bill arrives.

• Know When to Register for GST: As your business grows, you need to monitor your turnover. Once your gross income (before expenses) reaches $75,000 in any 12-month period, you are legally required to register for GST. This is a major change in your tax obligations. The only major exception is for ride-share drivers, who must register for GST from their first dollar earned.

You are legally required to notify the Australian Business Register (ABR) of any changes to your ABN details within 28 days.

This includes updating:

• Your business or postal address.

• Your contact details.

• Your main business activity.

You can update your details online for free using your myGovID to log in to the ABR website.

Running a business, especially in the early days, can be overwhelming. Knowing when to get professional help is a sign of a smart business owner.

Consider engaging a registered accountant or tax agent when:

• You are unsure about your tax obligations.

• Your income is growing, and you need advice on tax planning.

• It’s time to lodge your first business tax return.

• You are considering registering for GST.

Their fee is a tax-deductible expense and can save you from making costly mistakes.

Conclusion

Your ABN is your key to the Australian business world. By treating it with professionalism from day one, you set the foundation for a compliant and successful enterprise.

By creating proper invoices, keeping organised records, understanding your tax duties, and keeping your details current, you are not just ticking boxes—you are building a resilient and professional business. Remember to start with these good habits now, and your future self will thank you.
