Many EV purchases in the U.S. qualify for a Federal tax credit of as much as $7,500. But home chargers also allow for some healthy tax breaks. You can use this federal website to view the breakdown of which car manufacturers and their vehicles qualify for a tax credit. You may notice Tesla and GM are back on the list; a recent bill did away with their previous credit limit. You can claim a Federal tax credit of up to 30% of the charger's cost, up to a maximum of $1000. In addition, your state and your power company might offer additional credits. To check your possible savings, try this interactive incentive checker.
