As Bloomberg explains, while the government’s original plans anticipated to phase out tax breaks from 2016 to 2020, when they would be treated in the same way as fossil fuel-powered cars, on April 18, having taken note of the drop in sales, the government decided to change the rules.
"It’s no secret electrical vehicle sales have been below what we expected a year and a half ago," Tax Minister Karsten Lauritzen said in a statement. "The agreed phase-in has turned out to be hard and that likely halted sales."
The new rules mean the transition to a post-subsidy era has been postponed until at least 5,000 new electric cars are sold over the 2016-2018 period. Tax breaks will in any case be progressively eliminated as of 2019, regardless of sales numbers. The plan envisages a 40 percent registration tax minus a 10,000 kroner ($1,500) deduction in 2019, with the tax rising to 65 percent in 2021, 90 percent in 2021 and 100 percent in 2022.
...Should the rest of the world follow in Denmark's example, the same thing would happen to Tesla's market cap, which at last check amount to just over $800,000 per car sold..."
