Two people bought the same electric car this year. Same model, same trim, same price tag. Five years later, one of them has saved thousands over what a petrol equivalent would have cost. The other has barely broken even, and in a couple of US states, might genuinely have come out behind.

The difference isn’t the car. It’s everything that happens after the sale: which state or country the car is registered in, whether an employer is involved in paying for it, what a tax office decides an EV owner does or doesn’t owe. Total cost of EV ownership was never really a sticker price question. Lately it’s become a different question entirely depending on where you live.

THE US: CHEAPER TO RUN, BUT STATES WANT THEIR CUT BACK

Start with the part that’s straightforward. Consumer Reports found EV drivers spend roughly 60 percent less a year on fuel than petrol drivers. Energy Innovation’s research goes further: every EV model, in every US state, costs less to charge than the equivalent car costs to fill. Maintenance is lighter too, no oil changes, no spark plugs, longer-lasting brakes thanks to regenerative braking. A 2025 lifetime-cost study run for NRDC found EVs beat comparable petrol cars in four of five vehicle categories over a typical seven-year ownership period.

Here’s the catch nobody puts on the window sticker. Petrol taxes fund most US road maintenance, and EV owners simply don’t pay them. Thirty-nine states have noticed, and now charge EV owners an annual registration fee to close the gap, anywhere from $50 to over $400. Texas charges $400 in year one.

Oklahoma scales its fee by vehicle weight, reaching past $2,000 for the heaviest EVs. In several states that annual fee now beats what an equivalent petrol driver pays at the pump over the same year, which quietly erodes the very saving that made buying electric worth it in the first place.

A handful of states are trying something more honest: Oregon and Utah are piloting charges based on miles actually driven, rather than a flat fee regardless of use. If that model spreads, it will do more to your real EV running costs than any rebate a dealership will tell you about.

THE UK: THE FREE RIDE ENDS ON SCHEDULE

The UK shows where flat fees tend to go next. EVs only lost their exemption from Vehicle Excise Duty in April 2025; before that, EV owners paid no annual road tax at all. Now something larger is arriving behind it. From 2028, UK EV drivers face a road charge of roughly 3 pence per mile, with plug-in hybrids paying half that. A government spokesperson put it bluntly to the BBC: “Fuel duty covers petrol and diesel, but there’s no equivalent for electric vehicles.”

Reaction has been mixed, though not universally negative. One electric-car leasing founder told the BBC she still expects EVs to come out ahead even with the new charge, since the fuel and maintenance savings are large enough to absorb it. The UK is still heading toward its 2030 ban on new petrol and diesel sales. The incentives aren’t vanishing so much as being rebalanced as the government tries to plug a widening hole in motoring tax revenue.

AUSTRALIA: PULLING IN THE OPPOSITE DIRECTION, FOR NOW

Australia is running the reverse experiment. Rather than winding incentives back, current policy is actively pushing EV uptake, and the numbers back it up. The Electric Vehicle Council’s State of EVs 2025 report recorded a 24 percent jump in EV and plug-in hybrid sales in the first half of the year, with EVs now over 12 percent of new car sales, up from under 10 percent twelve months earlier.

The interesting mechanism isn’t a rebate at the dealership. It’s a tax structure most buyers never think to check. Since July 2022, eligible battery electric and hydrogen fuel cell vehicles bought under the Fringe Benefits Tax exemption avoid FBT entirely when financed through a novated lease, a three-way arrangement between an employee, their employer and a lender, where lease payments and running costs come out of pre-tax salary. For a vehicle under the luxury car tax threshold (just over $91,000), that exemption alone can be worth thousands over the life of the lease, stacked on top of the fuel and maintenance savings the car already delivers.

Worth being upfront: this isn’t permanent. The exemption is under active government review, and from April 2027 EVs priced above $75,000 will only get a 25 percent discount rather than a full exemption. The settings that make an EV novated car lease this attractive today won’t necessarily hold for every future buyer. Anyone weighing one up is, in effect, locking in a snapshot of current policy. Timing matters here as much as the car does.

THE REAL QUESTION ISN’T THE PRICE ON THE WINDSCREEN

Line these three markets up and a pattern appears. The US is discovering that letting EVs skip road funding indefinitely doesn’t work, and is patching the gap state by state. The UK worked that out earlier and is already rolling out its replacement. Australia hasn’t hit that wall yet, so it’s still using tax policy to pull people toward EVs instead of pushing them away.

None of that shows up on a sticker. A buyer comparing two identical EVs, one bought outright and one salary-packaged through an employer, isn’t really comparing cars. They’re comparing which country’s, and sometimes which employer’s, financial plumbing they happen to be plugged into. The car is the easy part. The tax rules wrapped around it are what actually decide whether going electric pays off.

Start the research at the sticker price. Don’t stop there. What your state, country or employer currently allows you to structure will usually matter more than the number in the window.
