EV Charging Station Credit - Any Credit for 2nd Station?

[HockeyMom12]

We installed 2 EV charging stations in 2023. We entered the full amount for both into form 8911 and do not appear to get the full credit for 1 (30% up to $1000) or any credit for the second. The full cost of the 1st one is $2454 and the full cost of the 2nd is $1233. Whether we enter one or both, the full credit that is calculated is $348. It seems that the credit for purchasing an EV ($7500) is negatively impacting the credit for the charging station in the way it is calculated. Is this correct that you can't get the full credit for a charging station if you are also getting a credit for the purchase of the car in the same year?

Yes, there may be a couple of reasons why you are not getting the full credit. AnnetteB6 mentions this in her Turbo Tax post. 

"First, the credit is non-refundable and you must have a tax liability in order to take advantage of the credit.  Also, the calculation of possible Alternative Minimum Tax (AMT) is involved in the calculation of the credit and may reduce it to zero.  

There is a tentative minimum tax for AMT that is calculated in the background as your return is completed. Form 8911 compares that tentative minimum tax to the net regular tax after certain other credits have been taken into account. If the tentative minimum tax is greater than the net regular tax, then the Form 8911 credit is disallowed."

Let us know if this helps.
