Gas tax write off vs electric tax write off

Hi, first post. I am close to acquiring a Model S.

I have a tax question. I use my ICE car for business and write off the gas. It is easy since I buy the gas, have proof of purchase, etc. Is it possible to measure and keep a record of the electric used to power the Tesla and write that off?
 
What did your CPA say?

From what little I know, it might be enough to keep a log of your charging sessions, or the kWh used from the car's trip meter. Your actual electricity usage will be a little higher, but it's difficult to record that without a separate meter and that's probably not worthwhile.

How expensive is your electricity? USA average cost is supposed to be around 10 cents/kWh, and you'll probably see something like 3 mi/kWh. That's only about 3 cents/mi, more or less according to how you buy your kWh. What about using the standard 54 cents/mile deduction for business driving? I think you'd have to keep a record of all your business miles with dates and odometer readings — but check that with your CPA.
 
We are about 19-20 cents per kWh.
keeping a log of everything is not going to happen :)
Since I don't own the car yet, didn't know if the car logged this kind of information.
Maybe some kind of meter to the outlet? Something simple. I have no idea, this is all new to me.
 
I think it would be easiest to take the standard deduction per mile rather than calculating the cost. But if you figure out your energy cost and track energy used each trip I think you can properly document the electricity cost and therefore deduct it as a vehicle expense.
considering that charging the car costs around 1/4 of the amount it would cost to fuel an ICE taking the very generous standard deduction could be the wise thing to do.
 
dominating the choice of standard mileage rate and itemizing the vehicle expenses will be depreciation, so the OP may certainly be better off with actuals over standard mileage rate depending on the percentage of personal miles to business miles.
