On Thursday, Nov. 2, 2017, the House Republicans unveiled their long-awaited tax plan, which was introduced as a Bill (H.R. 1) entitled the “Tax Cuts and Jobs Act” (the “Act”). While the Act has yet to be passed by the House, and it is likely to change in the legislative process, it contains proposals affecting the solar and wind industries which deserve to be carefully monitored. In addition to lowering income tax rates, which would, in general, make the tax benefits from investments in solar and wind facilities less valuable, as discussed in detail below, the Act would also make changes to the primary tax incentives relative to solar and wind facilities; namely, the investment tax credit and the production tax credit. While these changes may present planning opportunities, they also create issues and uncertainties, which hopefully will be clarified as the legislation progresses.
