IRS Private Letter Rulings (Wind)

Definition: A notice from the IRS that makes a ruling on how a particular portion of the tax code applies in a specific instance for an individual or business. Many community wind projects have asked the IRS for rulings on the ability of the project’s business structure to take advantage of the production tax credit (and other tax advantages) in a way that is within the law.
