When setting up a business in Australia, you will be asked to provide several different types of address across different registration systems. "Registered office," "principal place of business," "postal address," and "service address" all sound similar but they are legally distinct, held in different government systems, and used for different purposes.
Using the wrong address type in the wrong field or assuming all your addresses need to be the same is a common mistake that creates compliance problems down the track.
This guide clarifies each address type, what it means, where it appears, and how they interact.

The Five Address Types
| Address Type | Used By | Purpose | Public? |
|---|---|---|---|
| Registered office | ASIC (companies only) | Legal documents and ASIC correspondence | Yes |
| Principal place of business | ASIC + ABR | Where business is actually conducted | Yes (ASIC) / Limited (ABR) |
| Postal / mailing address | ABR | Where mail is received | No (ABR hides residential) |
| Service address | ASIC (business names) | Legal document service for business names | Yes |
| ATO correspondence address | ATO | Tax correspondence | No |
Registered Office Address (ASIC)
What It Is
The official legal address of a company as recorded with ASIC under the Corporations Act 2001.
Who Needs It?
Every registered company:
- Pty Ltd companies
- Ltd companies
- Other registered company structures
Sole traders and partnerships do not have a registered office requirement.
Legal Requirements
- Must be a real physical street address in Australia
- Must be accessible during business hours (minimum 3 hours between 9am–5pm, Monday–Friday)
- Must be capable of receiving legal documents
- If it is third-party premises, the occupier must give written consent
What Happens There?
Courts and regulators serve legal documents at this address.
Documents served here are legally deemed served by the company.
ASIC correspondence is also sent here.
Who Can See It?
Anyone.
The ASIC register is fully public and searchable.
Can It Be Different to Where You Operate?
Yes.
The registered office and principal place of business can be and often are completely different addresses.
Principal Place of Business (ASIC + ABR)
What It Is
The address where the business mainly carries on its activities.
Who Provides It?
- Companies provide it to ASIC during company registration
- All business entities (sole traders, partnerships, companies) provide it to the ABR during ABN registration
What Should It Reflect?
Where you genuinely operate your business:
- Your home (if you work from home)
- A commercial office
- A coworking space
- Any other regular operating location
Important
This address should accurately reflect where business activities are actually conducted.
ASIC guidance suggests it should not be a virtual address that you never physically occupy.
However, the registered office (a separate field) can legitimately be a virtual address.
Who Can See It?
ASIC Register
- Publicly visible for companies
ABN Lookup
- Residential addresses are hidden from public view
- Suburb and state remain visible
Postal / Correspondence Address
What It Is
The address where you want to receive mail.
Who Uses It?
The Australian Business Register (ABR) maintains a postal address linked to your ABN.
This is separate from your principal place of business.
Can It Be a PO Box?
Yes.
The ABR accepts PO boxes for postal purposes.
Can It Be a Virtual Address?
Yes.
Many businesses use a virtual address as their ABN postal address to ensure:
- Reliable mail receipt
- Better organisation
- Professional presentation
Who Can See It?
ABR postal addresses are not prominently displayed on ABN Lookup.
The business name and ABN are the main public-facing details.
Service Address (ASIC Business Names)
What It Is
The address where legal documents can be served on a business name registrant.
Who Uses It?
ASIC holds a service address for every registered business name.
Requirements
Must be:
- A physical street address
- Located in Australia
PO boxes are not acceptable.
Who Can See It?
Anyone.
The ASIC business name register is publicly searchable.
The service address appears on the register and is visible to anyone searching your:
- Business name
- ABN
Why It Matters
This is the address most sole traders and small business owners overlook.
It is also the most common reason a home address becomes publicly visible online.
Using a Virtual Address
A Space Penguin virtual address satisfies the ASIC service address requirement while keeping your home address private.
ATO Correspondence Address
What It Is
The address where the ATO sends:
- Tax assessments
- BAS statements
- Compliance notices
- Official correspondence
Who Uses It?
The Australian Taxation Office.
Importantly, the ATO maintains this separately from both ASIC and the ABR.
Requirements
There are no specific legal requirements beyond ensuring it is current and reliable.
Can It Be a Virtual Address?
Yes.
A virtual address with mail notification and scanning can help ensure you never miss an important ATO notice.
Who Can See It?
Nobody publicly.
ATO correspondence addresses are private.
How to Update It
You can update your ATO address:
- Through MyGov
- Via your tax agent
- By calling the ATO on 13 28 66
How They All Fit Together
For a typical Australian company operating remotely, the setup often looks like this:
| Address Type | System | Address Used |
|---|---|---|
| Registered office | ASIC | Space Penguin virtual address (Sydney/Melbourne) |
| Principal place of business | ASIC | Home address (where you actually work) |
| ABN principal place of business | ABR | Home address or virtual address |
| ABN postal address | ABR | Space Penguin virtual address |
| Service address (business name) | ASIC | Space Penguin virtual address |
| ATO correspondence address | ATO | Space Penguin virtual address |
This is a completely legitimate arrangement used by thousands of Australian businesses.
The key principle is:
- Registered office = legal address
- Principal place of business = where you actually work
They serve different purposes and do not need to be the same.
Can I Use the Same Address for Everything?
Yes provided the address satisfies the requirements for each purpose.
Many businesses use a Space Penguin virtual address for:
- Registered office
- Service address
- ABN postal address
- ATO correspondence address
while using their home address as their principal place of business.
This approach keeps your home address off public registers while maintaining compliance.
Using your home address everywhere is also compliant but it means your residential address may become publicly searchable through ASIC records.
For many business owners, that is a privacy trade-off they would prefer to avoid.
Using a Virtual Address for Each Type
| Address Type | Can Use Virtual Address? | Notes |
|---|---|---|
| Registered office (ASIC) | ✅ Yes | Must meet staffing and occupier consent requirements |
| Principal place of business (ASIC/ABR) | ⚠️ Technically possible, but not recommended | Should reflect where business is genuinely conducted |
| ABN postal address (ABR) | ✅ Yes | Commonly used |
| Service address (ASIC business names) | ✅ Yes | Must be a physical street address |
| ATO correspondence address | ✅ Yes | No restrictions |
Space Penguin addresses are commonly used for all of the approved use cases above.
Frequently Asked Questions
If I Change My Registered Office, Do I Also Need to Change My ATO Address?
Not automatically.
ASIC, the ABR, and the ATO are separate systems.
When changing your address, update:
- ASIC (Form 484)
- ABR (ABR portal)
- ATO (MyGov, tax agent, or ATO directly)
Which Address Appears on the ASIC Register?
For companies:
- Registered office
- Principal place of business
For business names:
- Service address
These addresses are publicly searchable.
Is My Home Address Visible If I Register an ABN?
Not usually.
The ABR no longer displays residential addresses on public ABN Lookup.
However, if you register a business name with ASIC, your service address becomes publicly visible on the ASIC register.
Using a virtual address prevents your home address from appearing there.
What Address Goes on My Invoices?
There is no legal requirement to include an address on a tax invoice.
If you choose to include one, it should generally be consistent with your business registrations, typically your virtual business address.
Can I Have a Registered Office in Sydney but a Principal Place of Business in Melbourne?
Yes.
There is no requirement for these addresses to be in the same state.
Many businesses operate with:
- Registered office in Sydney
- Principal place of business in Melbourne
or vice versa.
This is entirely acceptable under ASIC rules.
Space Penguin virtual addresses work for registered office, ABN postal address, ATO correspondence, and ASIC service address all from $20/month.
