I purchased a solar system for my home in 2022 and used the tax credits on my 2022 and 2023 tax payments. I am retired and normally do not have any taxes owed, but generate tax liability by doing Roth conversions on my traditional IRA in order to use the solar tax credits. I still have some solar credit remaining, but this year I purchased an EV and used the $7,500 tax credit at the time that I purchased the auto. My question is how will my solar credits be utilized, if at all in my 2024 tax return. I sent in estimated tax payment of $7,500 right after I purchased the auto. Will this amount be used to reimburse the $7,500 credit that I used when the auto was purchased, or will my solar tax credits be used first and the estimated taxes used for the balance (the remaining solar credit is less than $5,000) and the balance refunded to me?
