Owners Corporation Tax, GST & Interest: A Complete FAQ Guide for 2026
Managing an Owners Corporation (OC) comes with a surprising number of financial questions. Should your OC be earning interest on its funds? Do you need to lodge a tax return? When does GST registration kick in? Getting these answers wrong can mean unexpected tax bills, compliance headaches, and unnecessary costs for owners.
This guide breaks down the most common questions Owners Corporations ask about bank interest, tax obligations, and GST registration, so you can make informed decisions that benefit every owner.
Why Don’t Owners Corporation Bank Accounts Usually Earn Interest?
Most Owners Corporation funds sit in standard transaction bank accounts, which typically don’t earn interest. The reason is simple: these funds are primarily used for ongoing expenses such as maintenance, insurance, repairs, and day-to-day operations.
An Owners Corporation exists to manage and maintain the property, not to generate profit. Easy access to cash usually matters more than earning a small return.
That said, if owners want to earn interest on surplus funds, they can vote on it at a general meeting. If the motion is approved, funds may be placed in an interest-bearing account, such as a term deposit, provided this doesn’t compromise the OC’s ability to access money when it’s needed.
Key takeaway: Earning interest is possible, but it requires owner approval and shouldn’t restrict access to essential funds.
Does an Owners Corporation Need to Lodge a Tax Return?
An Owners Corporation must lodge a tax return if it earns more than $1 of non-mutual income. Non-mutual income can include:
- Interest earned from bank accounts or term deposits
- Income from leasing common property (for example, signage, equipment, or licences)
This income is generally taxed at 30%.
The Hidden Costs of Earning Income
Before chasing interest income, it’s worth weighing the costs involved:
- Tax agent fees typically range from $150 to $1,500 or more, depending on complexity
- Additional administration or accounting fees may also apply
Because of these tax obligations and associated costs, Owners Corporations should carefully consider whether the net benefit of earning interest actually outweighs the expenses. In some cases, a modest interest return can be eaten up entirely by compliance costs.
When Does an Owners Corporation Need to Register for GST?
The ATO usually classifies Owners Corporations as non-profit bodies. Under this classification, an OC must register for GST if its annual turnover exceeds $150,000.
Turnover can include:
- Levies and owner contributions
- Fees and charges
- Interest or other income
What GST Registration Means for Your OC
If your Owners Corporation is registered for GST, it will need to:
- Lodge Business Activity Statements (BAS), usually quarterly
- Charge and report GST where applicable
- Maintain proper financial records
GST registration also increases administrative and accounting requirements, so it’s important to factor in the added workload and cost.
How to Decide What’s Right for Your Owners Corporation
Before making decisions about investing funds or taking on new tax obligations, weigh up these three factors:
- Costs vs. financial benefits: Will the income actually exceed the cost of compliance?
- Cash flow and access to funds: Can the OC still cover expenses when needed?
- Compliance and administrative requirements: Is the OC prepared for the extra paperwork?
Get Professional Advice Before You Decide

A quick conversation with a professional can save your Owners Corporation from costly mistakes and help you choose the most financially sound path forward.
