Long story short

1
Stamp duty in SA is a one-off payment, not an ongoing tax

Stamp duty is generally payable when the property transfers into your name.

2
Stamp duty is based on the property’s value, location, and other things

Duty rates scale with the value of your home, but things like when you purchased the property can also affect how much you pay.

3
First home buyers could score full stamp duty relief on new builds

Eligible first home buyers may be able to get full relief, depending on the property type, value and contract date.

4
Foreign buyers may need to pay a 7% foreign ownership surcharge on top of stamp duty

Non-citizens, foreign corporations, and trusts incur this surcharge on the property’s value.

What is stamp duty?

Stamp duty is basically a land transfer tax on most real estate purchases not just in South Australia, but across the country. Like other taxes, the funds contribute to state government revenue, which funds public services. 

It’s also not an ‘ongoing’ tax – just a one-off payment. You only pay stamp duty once per property at the time of settlement, when the property you have purchased or acquired transfers to your name. 

You can find out how much stamp duty might set you back by giving our calculator a whirl.

How much is stamp duty in SA?

How much stamp duty you’ll be required to pay depends on a few things:

  • the value of the land (and any improvements made to it, if any)
  • whether you’re eligible for any exemptions or concessions
  • your residency status (like whether you’re a citizen or a foreign purchaser) 
  • the date you signed the dotted lines of your contract.

But for most home buyers, the stamp duty rates are based on the value of the property.

Stamp duty rates in SA

Value of the propertyStamp duty
$12,000 or less$1.00 for every whole or part $100
$12,001–30,000$120, plus $2.00 for every whole or part $100 over $12,000
$30,001–50,000$480, plus $3.00 for every whole or part $100 over $30,000
$50,001–100,000$1,080, plus $3.50 for every whole or part $100 over $50,000
$100,001–200,000$2,830, plus $4.00 for every whole or part $100 over $100,000
$200,001–250,000$6,830, plus $4.25 for every whole or part $100 over $200,000
$250,001–300,000$8,955 plus $4.75 for every $100 or part of $100 over $250,000
$300,001–500,000$11,330 plus $5.00 for every whole or part of $100 over $300,000
$500,001 and above$21,330 plus $5.50 for every whole or part of $100 over $500,000

Let’s have a go at the calculation. Say, for instance, you’re eyeing a property valued at $500,000. Your stamp duty based on the table is $21,330.

How to calculate stamp duty for a $500,000 property

$500,000 (value of the property) – $300,000 = $200,000

Divided by 100 = $2,000

Multiplied by 5 = $10,000

Added to $11,330 = $21,330

What property types does stamp duty apply to in SA?

In South Australia, if you’re buying residential property or land for farming, you’ll need to pay stamp duty for transfers that are considered ‘dutiable’. That means for properties like:

  • house and land packages
  • apartments
  • vacant blocks that are meant to be used for residential or primary production land.

For stamp duty purposes, ‘residential land’ means land you plan to live on as your main home. ‘Primary production land’ is land used for farming – like growing crops, running livestock, or horticulture.

Do first home buyers have to pay stamp duty in SA?

Stamp duty relief could apply to first home buyers if they’re buying a new home, an off-the-plan apartment, or a vacant land to build their new home on. It can apply if you (and your spouse or domestic partner) have never obtained stamp duty relief in Australia before.

Another thing to remember is that to qualify for this stamp duty relief, you need to actually live in the home or apartment as your main residence for at least six months straight. The six months need to start within any of the following:

  • 12 months of settlement if you’re buying a new home
  • 12 months from when you’re legally allowed to move in or 36 months from settlement (whichever comes first) if you’re buying vacant land.

Unlike the First Home Owner Grant, stamp duty relief for first home buyers isn’t money in your pocket. Instead, it means that if you’re eligible, you won’t have to pay the stamp duty that normally applies. It’s a relief, but not a windfall.

There’s a lot to keep track of. But don’t stress – you can always check with your broker, solicitor, or conveyancer to confirm your eligibility and what you need to do to stay eligible.

Are there any other stamp duty exemptions or concessions in SA?

There are some situations where you may be exempt from stamp duty (subject to eligibility rules).

What other fees might I need to pay besides stamp duty in SA?

Aside from stamp duty, it’s also a good idea to budget for a few other things so you’re not caught out when it’s time to deal with all the admin and paperwork. 

  • Conveyancing and legal fees: You’ll need a conveyancer or solicitor to handle all the legal paperwork when buying a home – things like preparing contracts and lodging documents. It’s not something you want to DIY. In SA, the cost is can vary around $1,800, but it can vary depending on complexity and who you hire. 
  • Building and pest inspection: Before you sign on the dotted line, it’s smart to get the property checked for structural issues and pests like termites. This can save you a fortune down the track.  A building inspection often costs a few hundred dollars; a combined building and pest inspection commonly ranges around $350-$700+ depending on property and provider.
  • Mortgage registration fee: This is a government fee for registering your lender’s mortgage on the property title. It’s collected by Land Services and varies by state. In South Australia, Land Services SA charges $198 to register a mortgage (fees can change). 
  • Loan application fee: Banks often charge a fee to set up your home loan. Some lenders waive it, but not always. This could set you back around $600, though it varies depending on who your lender is.
