IL
Haven't renewed it yet but I believe for EVs its $35 and the tag lasts 2 years. But this looks too good to be true so their may be some extra fees added that I'm missing.
This is the old rate. The State of Illinois raised fees for EVs from $35 every two years to $248/year and raised non-EVs from $98/year to $148/year. This starts in 2020. The old special EV rate applied a registration expiration date of 12/31/2019 for all EVs, so I assume the new rate will apply when you go to renew in December 2019 for 2020.
