Stamp duty is a tax that state and territory governments charge on certain transactions and documents, most commonly the purchase of property and the transfer of a vehicle.

Also known as: transfer duty, land transfer duty, motor vehicle duty, duty

Key points

  • Every state sets its own rates, thresholds, concessions and names: transfer duty in NSW, land transfer duty in Victoria, motor vehicle duty on cars.
  • On property it is calculated on the purchase price or market value, whichever is higher, and must be paid by settlement.
  • Lenders will not usually lend it: stamp duty comes from your own funds on top of the deposit.
  • Vehicle duty is charged when a car is registered or transferred, and it is often rolled into the amount financed on a car loan.

Frequently asked questions

Who pays stamp duty, the buyer or the seller?

The buyer, or more precisely the person the property or vehicle is transferred to. Sellers do not pay duty on the sale, although they may have their own capital gains tax to deal with. On a new car the dealer collects the duty from the buyer and passes it to the state revenue office.

Can stamp duty be added to my home loan?

Usually not. Lenders lend against the property's value, and the duty sits outside that, so it has to come from your own funds along with the deposit and fees. The exception is where you already hold enough equity in another property to borrow against. Vehicle duty is different and is commonly included in a car loan.

Is stamp duty tax deductible?

Not as an immediate deduction, and not at all on the home you live in. On an investment property or business premises the duty is added to the cost base, which reduces the capital gain when you sell. On a business vehicle or equipment it becomes part of the asset's cost for depreciation. Ask your accountant how it applies to your purchase.

When do I have to pay stamp duty?

Each state sets a deadline measured from the contract date, and settlement cannot proceed until the duty is paid, so in practice it is paid at or just before settlement through your conveyancer. On a vehicle it is paid when the car is registered or the registration is transferred into your name.

Do I pay stamp duty on a used car?

In most states, yes. Duty is charged on the transfer of registration whether the vehicle is new or used, based on the price paid or the market value if that is higher. Some states exempt transfers between spouses or on inheritance. The exact rate and any exemptions are on your state revenue office or transport authority site.
