Why the differences are so big
There is no federal vehicle tax. Cantons choose their own basis and rates, and several give eco-discounts for efficient or electric vehicles (sometimes temporary). Moving cantons can change your car's tax by hundreds of francs.
What to check before buying
Look up your canton's formula for the exact model: heavy SUVs and high-powered cars are penalised in weight/power cantons; EVs are often (but not always) discounted.
Plan it annually
Vehicle tax arrives once a year – put one-twelfth aside monthly so it never surprises you.

Why the same car costs different amounts
Vehicle tax is cantonal, and the basis differs fundamentally: some cantons tax by weight, others by engine displacement, others by power or emissions. The same car can therefore cost noticeably different amounts a few kilometres apart.
Several cantons grant reductions or exemptions for low-emission and electric vehicles, but the schemes are being adjusted as electric shares rise – a reduction granted this year is not a permanent entitlement.
The tax follows registration, which follows residence. Registering a vehicle in a cheaper canton without living there is not an optimisation, it is a false declaration.
What else the state charges on a car
The motorway vignette is an annual flat charge for using national motorways, valid for the calendar year with a grace period at each end. It applies to trailers separately.
The periodic technical inspection (MFK) has its own fee, and the interval depends on the vehicle age – newer cars are called less frequently. The inspection itself is modest; the repairs it triggers on older vehicles are what matter for a budget.
Fuel duty is embedded in the pump price rather than billed separately, which is why fuel feels like a variable cost even though a large share of it is tax.
Budgeting the annual charges
Vehicle tax, vignette and inspection all arrive as annual or periodic charges. Divide the expected total by twelve and provision monthly, in the same category as insurance – it turns three separate surprises into one invisible line.
Before buying, request the tax figure for the specific model from your cantonal road traffic office. On heavier vehicles in weight-based cantons, the difference between two models can exceed the fuel difference over a year.
When moving cantons, re-register within the required period and expect the tax to be recalculated pro rata – occasionally in your favour, occasionally not.
