When my wife and I bought our Teslas in 2018, we took advantage of the federal, state, and private (utility) incentives made available for EVs. Finding all the available incentives for electric vehicles and home EV chargers was a chore. Here is a list of federal, state, and private incentives broken out by the state. The federal does not apply to Tesla anymore. I hope the Tesla Motor Club community finds the list useful.
