Buying a Rent Roll: Retention, GST and Stamp Duty Explained
By James Alexander · 2026-10-02T00:00:00+10:00 · 9 min read
How retention clauses, GST and stamp duty change the cash you need to buy a rent roll in Australia, state by state, and how the finance is drawn to match.
Three terms in a rent roll contract decide how much cash you need at settlement, and none of them is the price. A retention clause holds back part of the price until the landlords have stayed. GST adds 10% to the price unless the sale qualifies as a going concern. And depending on the state, stamp duty can apply to the rent roll itself. Each one changes how the finance should be drawn, so they belong in the funding plan before the contract is signed, not after.
This article is general information about how these terms affect the funding of a purchase. It is not tax or legal advice. Confirm the GST and duty treatment of your transaction with your accountant and solicitor before you sign.
A rent roll is only worth the managements that remain after the change of agency. Retention clauses protect the buyer against the ones that leave. Part of the price is held back, usually by a third party such as the selling broker or a solicitor, for a set period after settlement. At the end of the period the portfolio is reassessed, the value of any lost managements is deducted, and the balance is released to the vendor.
Terms are negotiated deal by deal, but published industry guidance gives a sense of the range: holdbacks of roughly 10% to 20% of the price, for periods of about three to twelve months. These are market practice, not legal requirements. The longer the period and the larger the holdback, the more protection the buyer has and the longer the vendor waits to be paid.
The ATO's position is that the sale of a rent roll is subject to GST if the selling agent is registered, or required to be registered, for GST. On a $2.1 million purchase that is $210,000 on top of the price. The exception is a supply of a going concern, which is GST-free.
Under section 38-325 of the GST Act, a sale is a going concern where it is for payment, the buyer is registered or required to be registered, both parties agree in writing that it is a going concern, the vendor supplies everything necessary for the enterprise to continue, and the vendor carries on the enterprise until the day of sale.
Many agency sales are of the rent roll only, without the sales business. The ATO accepts that part of a larger enterprise can be a going concern if it is capable of operating independently: think separate management, its own staff and systems, and its own agreements with clients (GSTR 2002/5). A bare transfer of management agreements, with no staff, systems or premises going with them, is at greater risk of not qualifying. Whether a particular sale qualifies is a question for your accountant, and the contract should say clearly which treatment applies.
A registered buyer can generally claim the GST back as an input tax credit on its business activity statement, once it holds a valid tax invoice. The cost is temporary, but the cash is real: the buyer pays the GST at settlement and recovers it weeks later. That gap is why acquisitions often include a short-term facility for the GST amount, repaid when the credit is received. A share purchase is different. Selling shares in the agency company is a financial supply rather than a taxable sale of the business, so GST is not added to the price.
Most states and territories no longer charge duty on business assets sold without land. Queensland and Western Australia still do, and Western Australia's revenue office names rent rolls specifically. Where a sale includes land or a lease, duty can apply to that part in any state. The position as published by each revenue office:
Buying the shares in the agency company rather than its assets generally avoids business asset duty. Landholder duty can still apply where the company holds land above the state's threshold. Asset or share purchase is a bigger decision than duty alone, because a share purchase brings the company's history with it. It is worth weighing the two with your solicitor and accountant before terms are agreed.
The buyer needs its own licence to manage the properties. In New South Wales the Property and Stock Agents Act 2002 requires agents to be licensed. In Western Australia a licence is not transferable, so it cannot pass to the buyer with the business. Landlords' management agreements generally move to the new agency by assignment, with consent or notice depending on the state and the agreement. Bond records, trust accounts and regulator notifications also have to be updated. None of this is a finance step, but lenders will want to see that it is planned, because the income they are lending against depends on it.
For an asset purchase, the cash needed at settlement is broadly the price less any retention, plus GST if the sale is taxable, plus duty in Queensland or Western Australia, plus legal, due diligence and valuation costs. The lender funds a share of the assessed rent roll value, and the rest is the buyer's contribution. Each of those terms changes a different line, so the funding plan should be built from the contract, not from the headline price.
Usually, if the vendor is registered for GST, unless the sale qualifies as a GST-free supply of a going concern. A registered buyer can generally claim the GST back on its business activity statement, but has to fund it at settlement first.
It depends on the state. Queensland and Western Australia charge duty on business assets, and Western Australia names rent rolls expressly. New South Wales, Victoria, Tasmania, the ACT, South Australia and the Northern Territory do not charge duty on business assets sold without land.
A period after settlement, commonly three to twelve months, during which part of the price is held back. The portfolio is then reassessed, the value of any managements lost is deducted, and the balance is paid to the vendor.
