Stamp duty SA: what first home buyers need to know

Stamp duty SA is the one-off state government tax you generally pay when property changes hands in South Australia, and for most first home buyers it is one of the largest upfront costs after the deposit. The amount is set by the South Australian Government, not by your lender, and it is calculated separately from your home loan. This guide explains what stamp duty in South Australia is, when it is payable, how it is worked out at a high level, and where to find the current figures, so you can budget for it with confidence.

Because the rules and the dollar figures are set by the state and can change, this page points you to RevenueSA and a stamp duty calculator for the exact numbers rather than quoting a figure that may date. What stays steady is how the cost fits into your purchase, and that is what we cover here. If you are mapping out the bigger picture, the broader steps sit on our first home buyers hub.

What is stamp duty in South Australia

Stamp duty is a one-off state government property-transfer tax. In plain terms, when you buy a property the government charges a tax on the transfer of that property into your name. MoneySmart, the Australian Government’s money guidance service, describes stamp duty as a one-off state government property-transfer tax, and notes that it is charged by state and territory governments, so the amount and the rules vary depending on where you buy.

South Australia is its own jurisdiction, with its own rates and concessions administered by RevenueSA. So a search for stamp duty south australia, or for the SA stamp duty calculator, is really a search for the South Australian version of this same transfer tax. The principle is the same Australia-wide; the figures are specific to SA.

When do you pay stamp duty in SA

Stamp duty is an upfront cost, not something added to your loan over time. MoneySmart notes that you typically need to pay stamp duty within 30 days of settlement. In practice your conveyancer or solicitor usually arranges payment around settlement as part of completing the purchase, so the funds need to be ready alongside your deposit and other costs.

That timing matters for your budget. Stamp duty is paid close to settlement and is not usually rolled into the mortgage, so it is money you need available on top of your deposit. MoneySmart points out that you will also need to cover the other costs of buying a house, like stamp duty and legal fees, on top of your deposit.

How is stamp duty calculated in SA

The exact rate brackets and thresholds are set by RevenueSA and are best read straight from the source, because they can change and are specific to South Australia. At a high level, the amount of stamp duty generally rises with the value of the property, so a higher-priced home usually attracts more duty than a lower-priced one.

To get an accurate figure for your situation, the most reliable approach is to use the official SA stamp duty calculator and to check the current rates with RevenueSA. That gives you a number based on the actual property value and the rules in force at the time, rather than an estimate.

Work it into your overall budget

A stamp duty figure on its own does not tell you the full picture. It sits alongside your deposit, your loan amount and your other upfront costs. Knowing how much you can borrow first helps you set a realistic price range, and from there a stamp duty figure follows.

Try the borrowing power calculator to estimate your price range, then use the official SA stamp duty calculator for the duty on a property at that price.

Stamp duty and your deposit

Stamp duty changes how much cash you need before you buy, so it is worth planning around your deposit. MoneySmart suggests a common savings goal for a house deposit is 20 per cent of the purchase price, plus enough to cover buying costs, and notes that a 20 per cent deposit will avoid you needing to pay lenders mortgage insurance.

Lenders mortgage insurance (LMI) is a one-off fee that protects the lender if you cannot repay the loan; it does not protect you or your guarantor. MoneySmart notes that if your loan-to-value ratio is above 80 per cent you may need to pay LMI, and that some lenders may accept a deposit as little as 5 per cent, though a smaller deposit may mean higher costs like LMI. The point for budgeting is that stamp duty, your deposit and any LMI are separate costs that all need to be planned for together.

If a low-deposit path suits you, you can read how that works in our guide on buying with a 5 per cent deposit.

First home buyer concessions in SA

First home buyers may be able to reduce stamp duty, depending on the property and their circumstances. MoneySmart advises that if you are a first home buyer, you should check whether you are exempt from stamp duty or entitled to a rebate or concession. In South Australia, concessions and any first home owner grant are administered by RevenueSA, so the current eligibility rules and amounts should be confirmed there.

Whether a concession applies to you depends on factors such as the type of property, its value and whether you meet the eligibility criteria, which can change over time. Because the figures are set by the state, the safe step is to check your eligibility with RevenueSA before you budget on a reduced amount. We can also help you work out how a concession may affect the cash you need.

How stamp duty fits the rest of your costs

Stamp duty is one line in a larger set of upfront costs. Alongside it sit conveyancing or legal fees, building and pest inspections, and your deposit. MoneySmart advises getting help from a solicitor or conveyancer to review the contract before signing, which is a cost worth planning for in its own right. You can see how these add up in our guide to conveyancing costs for first home buyers.

Mapping these out early stops surprises at settlement. If you are buying in Adelaide or regional South Australia, a clear list of upfront costs, with stamp duty included, helps you set a deposit goal that actually gets you to settlement. Our guide to buying your first home in Adelaide and our first home buyer checklist walk through the full list.
