My tax program just denied me the federal 30% credit for installing EV charging equipment. After getting the $7500 EV credit for my e-golf, my tax liability went below the AMT (alternative minimum tax) amount. The program called it my TMT (Tentative min. Tax) and did not trigger the AMT payment but it disallowed any of the 30% credit for my EVSE or my electrical panel upgrade. As usual, I find the IRS instructions unclear. Has anyone heard of this problem?
