What electric cars pay in motor vehicle tax in Graubünden (Grisons), how the tax is calculated and what is changing.
In 2026, battery-electric cars in Graubünden still get an 80% reduction on a weight-based tax: an EV with a gross weight of 2,000 kg pays CHF 90.10 a year, while combustion cars are taxed on engine capacity. From 1 January 2027, a new system based on weight and power applies, with smaller discounts for EVs that expire at the end of 2034. The final amount is not yet confirmed: the government proposed 50% and later 25%, while media report 60%.
Until end-2026: combustion passenger cars are taxed on engine capacity, electric vehicles on gross weight (separate tax table of the Road Traffic Office), capped at CHF 3,000 (capacity) or CHF 5,000 (weight) per year (Art. 10 EGzSVG). From 1 Jan 2027: passenger cars are taxed on gross weight and rated power (total revision of the EGzSVG). The government's proposal set CHF 0.201 per kg plus progressive power rates of CHF 1.10 (up to 90 kW), 1.65 (over 90 to 180 kW) and 2.20 (over 180 kW) per kW. The final adopted rates have not yet been published.
Current law (2026): the traffic tax is reduced automatically by 80% for light motor vehicles emitting at most 90 g CO2/km (WLTP) and by 60% for those emitting at most 100 g/km (Art. 15 RVzEGzSVG), so battery-electric cars get 80%. The official EV tax table already includes this discount: an EV with a gross weight of 2,000 kg pays CHF 90.10 a year. According to the government, the reduction applies in practice with no time limit, until the vehicle is deregistered. New law from 1 Jan 2027: the Grand Council passed the total revision of the EGzSVG on 22 April 2026. Reductions for zero-emission vehicles are cut sharply and end in 2034. The government had proposed 50% for 2027 to 2030 and 25% for 2031 to 2034; media reports on the parliamentary decision say the reduction will be up to 60% until 2034. The final text has not yet been published in the official collection of laws. Under the government's proposal, the existing 60 to 80% reductions lapse for all vehicles when the new law takes effect, including those already registered, with no grandfathering.
2026: plug-in hybrids get the 80% or 60% reduction if their CO2 emissions are at most 90 or 100 g/km (WLTP) (Art. 15 RVzEGzSVG). For 2027 onwards, the government proposed 25% for plug-in hybrids from 2027 to 2030 and nothing thereafter; media report that, after the parliamentary decision, hybrids get at most 30%. The final figure has not yet been officially published.
From 1 January 2027, the fully revised traffic tax applies (Grand Council decision of 22 April 2026, 90 votes to 25 according to media): taxation on gross weight and rated power instead of engine capacity, no transition period, and sharply reduced discounts for electric and plug-in vehicles that expire on 31 December 2034. After that, EVs get no reduction unless the law is amended again.

The reduction rates and tax rates from 2027 finally adopted by the Grand Council on 22 April 2026 are documented only by media reports (nau.ch, Engadiner Post, Südostschweiz); gr-lex contains no new version yet. The media report a maximum of 60% for zero-emission vehicles until 2034 and at most 30% for hybrids; the government's message proposed 50%/25% and 25% for plug-in hybrids. It is unclear whether the 60% applies for the whole 2027 to 2034 period or is staggered. Also open: whether the optional referendum was called, when the government sets the change in force, and whether the Grand Council changed the transitional provision (no grandfathering). The EV tax table starts at 2,000 kg; the tax for lighter electric cars is not documented.
