I'm getting solar installed on my house in a few weeks. Since I'm financing it, I will qualify for the federal solar tax credit. I typically owe on my federal taxes about $4-6k. I want to make sure I max out the $8.5k credit I'll be able to claim. I currently claim 0 on my W-4 and wonder if I should adjust it to have less taken out so that I will owe more.
