One calculator, six states — the exact formula each revenue office uses

Queensland's cylinder-based rates, NSW's $45,000 premium band, Victoria's whole-of-value price bands, WA's sliding rate, SA's bracket scale and the ACT's emissions categories.

In most cases this is simply what you're paying for the car, including GST and any accessories fitted before delivery. Buying used below market value? States charge duty on the market value instead. (Revenue offices call this figure the “dutiable value”.)

Estimated stamp duty — Queensland
$1,500
That's 3.00% of the vehicle's value, on top of the price.
How it's worked out
Vehicle value used $50,000
Formula applied 500 blocks of $100 × $3.00
Stamp duty $1,500
Price + duty $51,500
Queensland notes: The rate applies to the whole value — crossing $100,000 lifts every $100 block to the higher rate, so a $200 price rise at the threshold can add over $2,000 in duty. Hybrids and EVs get the cheapest tier at any cylinder count. Duty is charged per $100 or part thereof (rounded up).
General information only — not personal financial or tax advice. Rates verified 18 July 2026 against each state revenue office. SA rates verified against secondary sources (RevenueSA blocks automated access) — cross-check large purchases with RevenueSA's own calculator. Common exemptions are not modelled: transfers between spouses, deceased estates, vehicles modified for people with disability, and primary producer vehicles may pay reduced or no duty. Heavy vehicles (over 4.5t GVM) and motorcycles use different rates and are not covered. Always confirm with the relevant state revenue office before purchase.

The two price cliffs worth knowing before you negotiate

Queensland and Victoria apply the higher rate to the whole value once you cross a threshold — not just the excess. A few hundred dollars off the price can save thousands in duty.

State & vehicle Just under Duty Just over Duty Extra duty
QLD — 4-cylinder $99,900 $2,997 $100,100 $5,005 +$2,008
VIC — passenger car $80,800 $3,393.60 $80,810 $4,212 +$818.40

By contrast, NSW's $45,000 premium band and every ACT band are marginal — only the amount above the threshold is charged at the higher rate, so there is no cliff to negotiate around.

How each state calculates motor vehicle duty

All rates as at 18 July 2026. "Whole value" means the rate applies to every dollar once a threshold is crossed; "marginal" means only the excess is charged at the higher rate.

State How duty is worked out EV / hybrid treatment
QLD Per $100 (or part) of the value, by engine type: $2–$4 per $100 up to $100,000; $4–$6 over $100,000 — whole value. Cheapest tier: $2 / $4 per $100 for hybrids and EVs.
NSW 3% up to $45,000; passenger vehicles then pay $1,350 + 5% of the excess over $45,000 — marginal. No concession — the EV exemption ended 31 Dec 2023.
VIC Per $200 (or part): $8.40 to $18.00 depending on type and price band — whole value. Green passenger rate $8.40 per $200 at any price (CO2 ≤ 120 g/km incl. all EVs).
WA Flat % of the value: 2.75% up to $25,000, sliding up to 6.5% from $50,000. No concession.
SA Bracketed per-$100 scale, topping out at $60 + $4 per $100 over $3,000 (non-commercial) or $30 + $3 per $100 over $2,000 (commercial). No concession.
ACT By CO2 emissions category (AAA–D): per-$100 base rate up to $45,000, then a percentage of only the excess — marginal. AAA (EV) is the cheapest category — the full exemption ended 31 Aug 2025.

Car stamp duty FAQ

How is car stamp duty calculated in Queensland?

Queensland charges vehicle registration duty per $100 (or part of $100) of the dutiable value, with the rate set by engine type: $2 per $100 for hybrids and electric vehicles, $3 for 1–4 cylinders, $3.50 for 5–6 cylinders and $4 for 7+ cylinders. Once the dutiable value passes $100,000, each rate rises by $2 — and the higher rate applies to the whole value, not just the excess. Worked example: a $120,000 4-cylinder car is 1,200 blocks of $100 at $5 each = $6,000 duty.

How much is car stamp duty in NSW?

NSW charges 3% of the dutiable value up to $45,000. For passenger vehicles over $45,000 a premium band applies: $1,350 plus 5% of the amount over $45,000. Example: a $60,000 car pays $1,350 + 5% of $15,000 = $2,100. Motorcycles, buses seating 9 or more, and vehicles modified for people with disability are excluded from the premium band and stay on the flat 3% rate. The former NSW electric vehicle stamp duty exemption ended on 31 December 2023 — EVs now pay standard rates.

Do electric vehicles pay car stamp duty in 2026?

Yes — in every state this calculator covers. Queensland gives EVs and hybrids its lowest tier ($2 per $100, or $4 over $100,000). Victoria charges EVs the green passenger rate of $8.40 per $200 at any price. In the ACT, EVs are category AAA — the cheapest emissions category — but the ACT's full EV duty exemption ended on 31 August 2025, so AAA vehicles now pay duty (many websites still wrongly say they are exempt). NSW, WA and SA charge EVs standard rates with no concession.

Is stamp duty charged on the GST-inclusive price?

Yes. The dutiable value is the total purchase price including GST and any accessories or optional extras fitted before delivery. For used vehicles, most states use the higher of the price you paid or the vehicle's market value — so a $1 'mates rates' transfer is still charged duty on what the car is actually worth.

Is car stamp duty different for dealer vs private sales?

The duty rates are the same whether you buy from a licensed dealer or a private seller — duty is charged on the dutiable value either way. The exemptions that exist apply to the traders themselves: licensed motor dealers generally do not pay duty on trading stock or demonstrator vehicles they register in their own name. As the buyer, you pay the same duty on the same price in both channels; the practical difference is that dealers usually collect and remit it for you, while in a private sale you pay it at transfer.
