How To Change Your Business Address In Australia (ASIC & ABN)

Moving offices, switching to a new warehouse, expanding into a bigger shopfront, or even changing from a home address to a serviced office - there are plenty of good reasons to change your business address.

But the admin side can feel surprisingly stressful. In Australia, your business address can appear across multiple registers (like ASIC and the ABR), plus your contracts, invoices, website, licences and more. If you miss an update, you can end up with important notices going to the wrong place, compliance issues, or confusion for customers and suppliers.

To make things easier, we’ve put together a practical, step-by-step guide to help you change your business address details properly - whether you run a company, a sole trader business, or you’re updating a business name.

Why Changing Your Business Address Matters (More Than You Might Think)

When you update your address, you’re not just tidying up your stationery. Your business address is often the official “point of contact” for legal notices and government correspondence.

If your details are out of date, you might miss:

• ASIC compliance notices (for companies and business names)
• ATO letters and deadlines
• banking or finance correspondence
• legal notices (like a letter of demand or court documents)
• supplier and customer communications

For companies, keeping ASIC records accurate is especially important because there are notification timeframes. If your registered office or principal place of business changes, you generally need to notify ASIC within 28 days.

From a practical perspective, having the right address listed also helps with:

• trust and credibility (especially if customers search your business online)
• deliveries and returns
• privacy compliance (your privacy documents often reference where your business is based)
• reducing disputes (contracts should clearly identify the correct business entity and address)

Which “Business Address” Do You Need To Update?

Before you jump into forms and logins, it helps to identify exactly what needs changing. In Australia, different addresses can apply depending on your business structure and how you operate.

Registered Office Address (Companies)

If you run a company, your registered office is the official address where ASIC and others can send documents. It must be a physical address in Australia (not a PO Box).

If you don’t own the premises, you’ll usually need permission from the occupier to use that address as your registered office.

Principal Place Of Business Address (Companies)

This is where the business actually operates from day-to-day (for example, your shop, office, warehouse, or primary worksite). It can be the same as the registered office, but it doesn’t have to be.

Business Name Address (Business Names Registered With ASIC)

If you operate under a business name, the address linked to that business name may also need updating. This is separate to (but often connected with) your company or ABN details.

Many business owners register and manage their details through the same system used for Business Name registration and maintenance.

ABN Address (Australian Business Register)

Your ABN details sit on the Australian Business Register (ABR). If you’re a sole trader, partnership, trust, or company, you’ll typically have ABN contact details that should be kept up to date.

Note: This guide is general information only and not tax advice. If you’re unsure how an address change affects your tax or reporting obligations, it’s a good idea to speak with an accountant or the ATO.

Trading Address Vs Postal Address

Many businesses have more than one address in play:

• Trading address: where you work from (and where customers might visit)
• Postal address: where you receive mail (this can be a PO Box)

It’s common to update one but forget the other - so it’s worth checking what each register is actually displaying.

Step-By-Step: How To Change Your Business Address

Below is a practical roadmap you can follow. The “right” process depends on whether you’re operating as a company or another structure - but the overall logic is the same: update the official registers first, then flow those changes through the rest of your business.

Step 1: Confirm What’s Changing (And When)

Write down:

• your old address (exactly as it appears on your records)
• your new address (including unit numbers, street names, and postcode)
• the date the change takes effect
• whether the new address is a physical location, postal address, or both

This sounds basic, but address mismatches happen all the time - especially if you’re moving into a building with multiple suites or using a serviced office.

Step 2: If You’re A Company, Update ASIC (Registered Office And/or Principal Place Of Business)

If you want to change your company’s address details, you’ll generally need to update ASIC. This is usually the key “legal” update for companies because it affects where official notices can be served.

When you update ASIC, you’ll typically be looking at changes to:

• the registered office
• the principal place of business

Tip: If the registered office is not owned by the company (for example, it’s your accountant’s office or a co-working space), make sure you have consent to use that address. Keeping a record of that consent can help if questions come up later.

Step 3: Update Your ABN Details (ABR)

Even if you’ve updated ASIC, you may still need to update the ABR so your ABN details match your current address.

This matters because many third parties check ABN details when deciding whether to do business with you, including suppliers and larger customers doing onboarding or compliance checks.

If you have an online presence, consistent ABN/address details can also reduce confusion when customers search for your business.

Step 4: Update Your Business Name Address (If You Use One)

If your business trades under a business name, you may need to update the address connected with that registration as well.

This is a common “gotcha” for growing businesses: you update the company details but forget the business name details. If your invoices, website, and signage use the business name, you want the public-facing records to stay accurate.

For many small businesses, this step sits alongside general housekeeping for business registrations - similar to what you would do when setting up your structure via Company set up in the first place.

Step 5: Record The Decision Internally (So Your Paper Trail Matches)

Not every business needs formal internal paperwork to change business address details, but having a clear record can save headaches later - especially if there are multiple directors, investors, or a head office and branch structure.

For companies, it can be sensible to document the change with a directors’ resolution, particularly where:

• your registered office is changing
• you’re changing where company records are kept
• the move affects operational responsibilities (like who receives legal notices)

You can capture this using a directors resolution template (tailored to your circumstances, where needed).

Step 6: Update Your Contracts, Invoices, And Business Documents

Once the official registers are updated, make sure your “real-world” documents catch up.

At a minimum, review and update:

• invoice templates (including your footer details)
• quotes and proposals
• purchase orders
• letterheads and email signatures
• your website footer and contact page
• any customer-facing “Contact Us” pages on marketplaces or directories

If you have standard terms and conditions, service agreements, or supply contracts that identify the business and its address, update these too - particularly if notices must be served to a specific address.

Don’t Forget These Other Places To Update Your Company Address

Once you’ve done the core “register” updates, the next step is to prevent loose ends. Address changes tend to ripple through your operations, and missing one update can create avoidable delays.

Banking, Finance, Insurance And Leases

Consider notifying:

• your bank and any lenders
• your merchant facilities provider
• your insurers (public liability, professional indemnity, product liability, etc.)
• your landlord (if you have a lease) or your tenants (if you sublease)

Be especially careful where your finance documents list an address for notices or where the move changes what you’re insuring (for example, stock stored at a new warehouse).

Customers, Suppliers And Service Providers

Think about all the parties who send or receive goods and documents from you:

• key customers (particularly B2B customers with onboarding systems)
• suppliers and wholesalers
• couriers and logistics providers
• your accountant and bookkeeper
• your IT provider and domain host

If you’re changing addresses to scale up operations, it’s also a good time to check whether your supplier and customer terms are still fit-for-purpose (for example, delivery responsibilities, risk of loss, or notice requirements).

Your Website Legal Documents (Including Privacy)

If your website collects customer enquiries, mailing list sign-ups, or online orders, your legal documents may reference your business location or contact address.

Make sure you review your Privacy Policy and any website terms so your contact details are accurate and customers know how to reach you.

Employment Documents And Workplace Details

If you have staff, an address change often affects your onboarding documents and workplace policies.

You should update:

• employment contracts (if they reference a specific workplace location)
• your employee handbook or policies (where relevant)
• any WHS documentation and incident reporting details

If you’re issuing new contracts or variations, it can be worth reviewing your Employment Contract templates to make sure they reflect the new arrangement (for example, if your move changes whether staff are office-based, hybrid, or working across multiple locations).

Common Mistakes When You Change Business Address (And How To Avoid Them)

Changing your business address is usually straightforward - the issues come from forgetting that the same address appears in multiple places.

1. Updating Only One Register

A very common scenario is updating ASIC but forgetting the ABR (or updating the ABR but not ASIC). Another common issue is forgetting that your business name registration has its own details to maintain.

How to avoid it: Make a quick checklist of every “identity layer” in your business:

• company details (if you have a company)
• ABN details
• business name details
• licences and permits
• contracts, website, and invoices

2. Confusing The Registered Office With The Trading Address

For companies, the registered office is an official address and must be a physical address in Australia. Your trading address might change more frequently, especially if you operate pop-ups, multiple sites, or a mobile business.

How to avoid it: Decide whether you actually need to change the registered office, or whether you only need to change your principal place of business and ABN trading address.

3. Forgetting “Notices” Clauses In Contracts

Many contracts include a “notices” clause that specifies where formal notices must be sent (and sometimes how, such as by email plus post). If you change your business address but your contracts still list the old address, you can create a dispute about whether a notice was validly served.

How to avoid it: As part of your address change, review your key contracts (especially high-value supply agreements, commercial leases, and ongoing service contracts). If needed, use a formal contract variation so the update is clear.

4. Updating Public-Facing Information Too Late

Even after you update the official registers, customers may still be relying on your website, directories, social media profiles, and Google listings (if you have them) for address details.

How to avoid it: Set an internal “go live” time where you update all public-facing address references in one sweep, ideally just before or on the day the move happens.

5. Not Updating Your Business Systems

Sometimes the “address” that causes the biggest disruption is in your internal systems - for example:

• accounting software invoice defaults
• shipping platforms and return addresses
• payroll systems
• online store settings (dispatch and returns)

How to avoid it: Assign one person (internally or externally) to own the change from start to finish, and have them confirm completion in each system.

Key Takeaways

• When you change business address details, you may need to update multiple “layers” of records - including ASIC (for companies), the ABR (for ABN details), and your business name registration.
• For companies, make sure you understand the difference between the registered office and the principal place of business, and update the right one (or both) as needed.
• After the official updates, flow the address change through your contracts, invoices, website, and customer-facing materials to avoid confusion and disputes.
• If you have employees, check whether your employment documents and workplace policies need updating for the new location.
• Keeping a clear internal record of the change (like a directors’ resolution) can help if questions come up later, especially in multi-director businesses.
