How To Legally Change a Business Name in Australia

Thinking about rebranding or updating your business name? A fresh name can signal growth, reflect a new direction, or help you stand out in a competitive market.

But there’s a right way to do it legally in Australia, and a few traps to avoid along the way. Whether you’re a sole trader, partnership or company, this guide walks you through the steps, what to update, and how to protect your new brand from day one.

Let’s break it down so you can change your business name with confidence and keep trading without disruption.

Do You Need A New Business Name Or A Company Name Change?

First, it’s important to know the difference between a “business name” and a “company name.” They’re not the same in Australian law.

• Your company name is the legal name of your company as registered with ASIC (it ends with “Pty Ltd”).
• Your business name is a trading name you register and use to conduct business under your ABN (for sole traders, partnerships and companies).

If you’re a sole trader or partnership and want to trade under a different name, you’ll typically register a new business name and cancel the old one. If you’re a company and want to change the legal name of the company itself, you’ll complete an ASIC company name change.

If you’re unsure which applies to you, it helps to revisit how a business name vs company name works in practice, and how an entity name vs business name differ in Australia. Getting this right at the start will dictate the correct process and save you time.

Step-By-Step: Changing Your Business Name (Sole Traders & Partnerships)

If you operate as a sole trader or partnership (or a company that trades under a separate business name) and you want to change your trading name, you don’t “edit” a business name. You register a new one and then cancel the old name when you’re ready to switch.

1) Check Name Availability And Risks

Search the ASIC business names register to confirm the name is available and not identical or nearly identical to an existing registered name. Also consider whether the name could infringe someone’s trade mark (we cover trade marks below).

2) Register The New Business Name

Register the new trading name against your ABN. You can manage this in one go with Sprintlaw’s Business Name service if you’d like support with the paperwork.

3) Decide When To Switch Over (And Cancel The Old Name)

Plan a short transition period so you can update your website, invoices, email footers, signage and marketing. Cancel the old business name once your new name is live and customers have been notified. It’s normal to keep both active briefly to avoid confusion.

4) Update Your ABN And Key Records

• Update your ABN details on the Australian Business Register to reflect the new trading name.
• Notify your bank, payment processors and any marketplaces you use.
• Update licences and permits, industry memberships and insurance records where required.

Tip: Keep a checklist and work through it systematically so nothing gets missed.

Step-By-Step: Changing A Company Name With ASIC

Changing a company’s legal name is a formal ASIC process. Here’s how it works in practice.

1) Choose Your New Name (And Check Availability)

Confirm the proposed company name is available and suitable (no restricted words, not identical to another company). Also consider brand conflicts and trade mark risks so you’re not forced to rebrand again later.

2) Pass A Special Resolution Of Shareholders

Company name changes require a special resolution (at least 75% of votes) of shareholders. The board typically calls a meeting, circulates the resolution, and records votes and minutes.

To document decisions properly, it’s helpful to keep clean records such as a simple Directors Resolution for the board approval alongside the shareholders’ special resolution.

3) Lodge The Name Change With ASIC And Pay The Fee

Once approved, lodge the Form 205 (Change of Company Name) with ASIC and pay the prescribed fee. ASIC will issue an updated certificate confirming your new name. If you need to reference it later, here’s an overview of the ASIC Certificate of Registration.

4) Update Company Registers, Stationery And Records

• Update the company register, share certificates (if any) and internal records with the new name.
• Refresh your letterhead, invoices, email footers, website footer and any “Pty Ltd” references.
• Notify the ATO, bank, insurers and any critical suppliers. If the company also uses a separate business name, ensure those details remain accurate too.

From here, your focus turns to brand protection and rolling updates across your contracts, policies and platforms (covered below).

Don’t Forget: Trade Marks, Domains And Contracts

A name change is a great time to protect your brand and tidy up your legal documents. The aim is simple: make sure your new name is clear, consistent and protected across the board.

Protect Your Brand With Trade Marks

Registering your brand as a trade mark gives you exclusive rights to use that name (or logo) for the classes of goods and services you specify. This is different to registering a business name or company name, which doesn’t provide brand protection by itself.

If your rebrand is important to your growth, consider filing a trade mark for the name and logo via Register Your Trade Mark. This helps prevent others from using confusingly similar branding.

Secure Domains And Social Handles

Snap up relevant domain names (including .com.au if eligible) and social media handles before you announce the rebrand. This reduces the risk of impersonators and helps customers find you easily.

Update Customer-Facing Legal Docs

• Privacy Policy: If you collect personal information from customers or website visitors, make sure your Privacy Policy shows the new name and correct entity details.
• Terms and Conditions: Your sales terms, website or app terms, and refund policies should all reflect the new name and ABN or ACN.
• Invoices and Quotes: Update templates so tax invoices meet ATO requirements and customers aren’t confused by mismatched names.

These updates are more than cosmetic-consistent information helps you meet obligations under the Australian Consumer Law when advertising, selling and handling refunds and complaints.

Update Your Legal And Regulatory Details

Once your new name is in play, work through this update list so everything stays compliant and consistent.

• ABN/ACN Details: Update your trading name (for ABN holders) and ensure ASIC records (for companies) reflect the new name.
• Licences And Permits: Some licences are tied to your trading or company name. Check each regulator’s update process and timelines.
• Banks And Payment Providers: Update bank accounts, merchant facilities, EFTPOS, and online payment gateways so settlements and statements show correctly.
• Insurers: Notify your insurer-policies typically identify the insured by name and entity details.
• ATO And Payroll: Ensure PAYG, BAS and GST records reflect the new name, and that pay slips are updated.
• Supplier And Partner Contracts: Amend schedules or issue a formal notice of name change so purchase orders and invoices match.
• PPSR Registrations: If you register or rely on security interests (or others register against you), ensure the grantor name and related details remain correct to avoid validity issues.
• Marketing And Legal Notices: Refresh email signatures, website footers and customer notices. Keeping communications clear helps avoid misleading or deceptive conduct risks.

It’s sensible to keep a central register of where your name appears (systems, contracts, listings, marketplaces) and tick them off as you update them. This keeps the process controlled and avoids gaps.

Common Mistakes To Avoid

• Skipping the trade mark check: A business or company name registration doesn’t stop someone with an earlier trade mark from objecting to your use of the name. Always do a trade mark search before you commit.
• Only changing the logo: If you’re changing the legal name of the company, you must complete the ASIC process and obtain the new certificate-branding alone isn’t enough.
• Leaving contracts and policies behind: Out-of-date terms, privacy notices and invoice details can confuse customers and create compliance issues.
• Forgetting licences and marketplaces: Food, building, professional and other licences (and platforms like Amazon, eBay or app stores) often require updates to entity and trading names.
• Announcing too early: Secure trade marks, domains and social handles first, then announce. This protects your brand and reduces the chance of copycats.
• Mixing up business name vs company name: If you’re a company, your “Pty Ltd” name is different to any business name you use. Keep both records accurate and aligned.

Key Takeaways

• Know the difference between a business name and a company name-your process depends on which one you’re changing.
• Sole traders and partnerships typically register a new business name and cancel the old one; companies change their legal name via an ASIC special resolution and filing.
• Protect your rebrand by registering trade marks, securing domains and updating customer-facing legal documents (like your Privacy Policy and terms).
• Systematically update ABN/ASIC records, licences, banks, insurers, payment providers and contracts so everything aligns with your new name.
• Avoid misleading customers during the transition by keeping communications clear and consistent across your website, invoices and marketing.
• If in doubt, get tailored help with the ASIC process, resolutions and brand protection so your changeover is smooth and compliant.
