A blow below the belt for green transition believers. Electric cars face new taxes

How can a country that only yesterday handed out purchase incentives worth thousands of dollars now start squeezing the same drivers with extra taxes? The answer is pragmatic, dry and mathematically unavoidable. States need taxes to function. If transport is going through its biggest technological shift in a century, the tax system has to move with it.

The fuel duty model is fading

For decades, road building and maintenance relied on a simple but effective idea: fuel duty. The more you drove, and the heavier your vehicle was, the more fuel you used and the more tax you paid through the pump. It was the classic user pays model, and it provided a steady flow of money for keeping roads in decent shape.

Electric cars have largely slipped past that system. Their owners use street lighting, wear down asphalt, often more than comparable combustion cars because of battery weight, and sit in the same traffic queues. Yet they do not contribute through fuel duty.

Whether the car is charged at home or at a public station, the treasury gets far less from the journey than it did in the petrol and diesel era. For US states, the reaction is therefore not some ideological ambush, but a form of self defence. If the tax base disappears while road costs remain, the rules have to change before the infrastructure falls apart.

The incentive era is ending

The first generation of electric car buyers enjoyed state privileges, and there was a reasonable argument for that. New technology needed help, and early adopters took risks that wider society wanted them to take.

That phase is passing. Electric cars are no longer niche experiments. They are becoming mass market products, and in many segments they are moving closer to price parity with petrol cars. Governments cannot subsidise them forever. On the contrary, once a new technology becomes normal, it must start paying its own way.

The irritation among consumers is easy to understand, but economically short sighted. The idea that an electric car owner should remain permanently exempt from funding roads simply because the car produces no tailpipe CO2 is fantasy. Welfare systems, schools, rescue services and the smooth asphalt beneath the tyres are not financed by good intentions or green slogans.

Mileage may become the fairest measure

How should taxes be collected in this new reality? The fixed annual fees now being tried in parts of the United States, often between $100 and $300, around €90 to €275, are only a transitional tool. They are blunt. They do not care whether a car travels 2000 kilometres a year or 50,000.

The future of transport taxation will almost certainly be based on distance travelled and vehicle weight. Digital systems, GPS based positioning and annual odometer checks during roadworthiness inspections all point in the same direction. It is the only way to restore a sense of fairness: you pay according to how much shared space you actually use.

Electric cars must pay their share

The electrification of the car industry is not just a change of engines. It is a reset of the entire economic model behind transport.

Countries that begin the tax debate early, as some US states are doing now, give themselves a better chance of maintaining decent roads and stable budgets. Those that continue to rely on fuel duty forever will wake up in a decade with broken roads and empty coffers.

The world is changing, and taxes will change with it. Electric cars may be cleaner at the tailpipe, but they are not weightless, roadless or free.
