Same Car, Eight Prices: what it costs to put an identical car on the road in every state (2026)

$1,371.45 first-year gap, cheapest state to dearest

NT $2,199.25 · WA $3,570.70 — a 62.4% spread on stamp duty, registration and compulsory injury cover for one $45,000 vehicle

All 8 official schedules · current as at 17 July 2026

Every state and territory prices the same act, putting a car on the road, in its own way. One charges duty per part of the price, another a percentage of the whole price, another scales the rate to the vehicle's emissions. Registration is priced on weight in some places, on cylinders in others, on engine capacity or emissions elsewhere, and in Victoria on where the car is garaged. Compulsory injury cover is a set government charge in most of the country, a competitive insurance market in New South Wales, and a single government premium in Tasmania.

That makes most cross border comparisons close to meaningless, because the states end up being compared on different cars. This study fixes the car. One vehicle, specified once, is run through all eight jurisdictions' own published schedules, so every difference below comes from the schedule rather than from the vehicle.

Included belowNSW figures on this page include the $100 NSW private vehicle registration discount. The NSW private vehicle registration discount is a one-off $100 reduction to the annual motor vehicle tax, applied automatically to registrations with an effective renewal date from 1 September 2026 to 31 August 2027. It is not limited to renewals: it also applies when a new light vehicle or motorcycle registration is established, so the new car in this study qualifies. Every NSW figure above is net of it. Without it this car's first year in NSW would be $2,398.00–$2,582.30 rather than $2,298.00–$2,482.30, and its annual registration and injury cover $1,048.00–$1,232.30 rather than $948.00–$1,132.30 — a difference that moves NSW from 6th to 3rd of eight on the first-year table, and from 8th to 7th on the ongoing tableACT becomes the dearest place in the country to keep the car. Because the discount is one-off, NSW returns to the undiscounted figures for registrations dated after 31 August 2027. Not available on vehicles registered for business, private trailers and caravans, plant vehicles, heavy vehicles, conditionally registered vehicles such as historic and farm fire fighting vehicles, and vehicles already receiving a registration concession, discount, refund or rebate.

New mid-size SUV: 4-cylinder, 2.0-litre (1,998 cc), 1,450 kg tare, 160 g CO₂/km combined, bought new, garaged in the capital city. Ranked on the midpoint where compulsory cover is a market range (QLD, NSW, SA); every other total is a single published figure. ‡ NSW is the exception to “the same car everywhere”: every other jurisdiction's compulsory injury cover is computed for this car's own class from a published schedule, but a NSW green slip is an insurer's quote, and the range used here was priced on a 2020 Toyota Corolla sedan — a Class 1 passenger vehicle — garaged in Sydney metro, with a 37-year-old clean-record owner-driver, over 12 months. NSW green slips are priced per vehicle, garaging postcode, driver age and driving record, so wherever this range stands in for a different car it is a class-level proxy for a Sydney passenger vehicle rather than a quote for that car. The official SIRA price check returns the exact price for your own details.

What the annual bill is actually made of

No two jurisdictions itemise the same way. These are the components each authority publishes, in its own language, for this car:

‡ The NSW green slip line is a class-level proxy, not a quote for this study's car. Sydney metro, 2020 Toyota Corolla, 37-year-old clean-record driver, 12 months — quoted across all six insurers on the official SIRA price check, 17 July 2026. Your quotes will differ. NSW green slips are priced per vehicle, garaging postcode, driver age and driving record, so wherever this range stands in for a different car it is a class-level proxy for a Sydney passenger vehicle rather than a quote for that car. The official SIRA price check returns the exact price for your own details. Prices include the Fund Levy and GST (per SIRA). CTP must be in place before rego can be renewed. The spread between insurers was $184 a year for identical details — run the official SIRA price check for your exact price; regional premiums are lower.

The recurring bill tells a different story

Stamp duty is paid once. Registration and compulsory injury cover are paid every year, and they rank the jurisdictions in a different order. On the midpoint of the green slip range — the basis this table and the one above use — ACT, 4th on the first-year table, is the dearest place in the country to keep the car on the road, and TAS the cheapest at $410.23 a year less. That order holds across the whole quoted range: even on the cheapest green slip on offer, ACT is still the dearest place to keep the car, at $1,053.00 a year.

Change the car and the ranking changes

The order is not a league table. It is an artefact of the price of the car and of the way each formula bends. A state that charges a percentage of the whole value punishes an expensive car and treats a cheap one gently. A state with a flat rate per part of the value barely notices the difference. Change the car and the ranking rearranges itself, which is why a single cheapest state headline is almost always wrong.

The same car, electric

Electric vehicles are where the remaining concessions live, and they are now a duty story rather than a rebate story. The cash grants have closed across the country. What survives is written into the duty formulas themselves: a territory that waives duty below a value cap, a state that gives electric and hybrid cars their own cheaper class, and a territory that rates duty by emissions and so charges the cleanest cars the least. The strip below holds the price constant and changes only the drivetrain.

Registration is a separate question and is deliberately left out of it, because the concessions differ again and several are conditional. Each state's own electric vehicle page covers what applies there.

Methodology

The vehicleNew mid-size SUV4-cylinder, 2.0-litre (1,998 cc), 1,450 kg tare, 160 g CO₂/km combined, bought new, garaged in the capital city, priced at $45,000 as its dutiable value. Used mid-size car4-cylinder, 2.0-litre (1,998 cc), 1,400 kg tare, no recorded CO₂ rating (the usual case for a used car), garaged in the capital city, priced at $25,000. No make or model is named: these are stated specifications, chosen because every jurisdiction needs a different fact about the car (tare weight in NSW and VIC and WA, cylinders in QLD, SA, TAS, CO₂ category in the ACT, engine capacity in the NT, garaging zone in VIC) and the specification has to satisfy all of them at once.

The build is deliberately boring, which is the point. The same two engines that run the calculators on this site produce every number here: one applies each revenue office's published duty formula, the other applies each road authority's published fee schedule. Nothing is typed in by hand, nothing is averaged across states, and no figure is nudged to make a point.

Where a state leaves a genuine range rather than a single price, the range is shown and the ranking uses its midpoint. That happens in three places, all of them compulsory injury cover: New South Wales, where green slips are sold by competing insurers; Queensland, where the driver picks a licensed insurer at renewal; and South Australia, where the premium comes from a five insurer market. Everywhere else the total is a fixed published figure.

Two limits are worth stating plainly. The first is that this is a capital city car. Compulsory injury cover is priced on where the vehicle is garaged, so a country address moves the figure in several states, most sharply in Victoria, where the charge is set by risk zone.

The second is scope. The study covers the charges every buyer of the same car faces: duty, registration, compulsory injury cover and the levies attached to them. It leaves out the costs that vary by transaction rather than by state, including plates, transfer and inspection fees, dealer delivery, and anything financed or optional. Those are real, but they are not published on a comparable basis across all eight jurisdictions, and including one state's version of them would flatter or punish that state for no good reason.

Caveats worth reading before you quote a number

Worked examples

The two ends of the duty table, as each revenue office calculates them. WA applies 5.75% of the full dutiable value: rate = 5.75%; $45,000 × 5.75% = $2,587.5. The NT applies $3 per $100 (or part): 450 × $3 = $1,350. Every other cell in the tables above is produced the same way — run any of them yourself on that state's duty calculator.

Frequently asked questions

Which state is cheapest to put a new car on the road in 2026?
On this study's car, the Northern Territory is cheapest at $2,199.25 for the first year, and Western Australia is dearest at $3,570.70 — a difference of $1,371.45, or 62.4%. Both figures are stamp duty plus twelve months of registration and compulsory injury cover.
Why is WA the most expensive?
Almost entirely stamp duty. WA charges 5.75% of the full dutiable value, which is $2,587.50 on this car, against $1,350.00 in the four jurisdictions that sit at the bottom of the duty table. Its ongoing bill is unremarkable: $983.20 a year, mid field.
Is the cheapest state the same for a cheaper car?
No. On the $25,000 used car the order rearranges: TAS becomes cheapest at $1,392.77 and VIC dearest at $2,008.80, a $616.03 gap. WA, dearest on the new car, drops to 5th.
Can I register the car in a cheaper state to save the money?
No. A vehicle must be registered where it is garaged. Giving an interstate address to get a lower bill misstates the garaging address, which can void both the registration and the compulsory injury cover, and the cover is the part that matters if someone is hurt.
What is not in these numbers?
Plates, transfer and inspection fees, dealer delivery, comprehensive insurance, fuel and servicing. The study covers only the compulsory government charges on the same car: duty, registration, compulsory injury cover and the levies attached to them. Concession and pensioner rates are not applied.
