Purchase incentives 2026: Switzerland has no nationwide purchase incentive for a new electric car — the federal government pays no bonus at purchase. Support is largely cantonal and varies widely: some cantons grant a discount on, or a full waiver of, the Motorfahrzeugsteuer (cantonal motor-vehicle tax) for electric cars — in some cases over several years — and some municipalities or energy utilities help fund a wallbox installation. A uniform purchase grant, however, does not exist. Not everyone benefits equally — which is why we list these advantages separately and do not count them into the total cost above.
