And I think its just a tax "credit", so it would be "up to" 26%, so if 26% exceeds what you would owe in taxes, at that point you would just pay 0$ tax...would not get refund of the "excess" stove/install costs. Still the best incentive I've seen yet!
It's not "just" a credit, it's a credit - which is good (as in much better than deductions)! However, it is unfortunately not a "refundable tax credit". The latter would have allowed to get the full 26% even if your tax bill was already zero.
