With the passage of the Inflation Reduction Act, new and existing national tax credits will encourage the adoption of more energy efficient building systems and constructing renewable energy facilities. The standard investment tax credit for a new qualifying solar or wind energy is six percent while the bonus tax credit for investing in low-income communities is worth 10 additional percentage points.
There is even an option, in the same areas, to gain an additional 10 points if constructing the facility on a qualifying rental residential building or if it will benefit low-income households.
Chicago Cityscape has added this geographically-based "IRA solar & wind bonus credit" to Incentives Checker. Search for it within Incentives Checker using the keywords IRA, solar, wind, or energy.
